The Anti Spam Challenge – Minimizing False Positives

Posted by benz | Posted in Anti Spam Appliance Articles | Posted on 01-09-2010

Email is the quintessential business communication tool, so when it doesn’t work like it’s supposed to, business suffers. Anti spam software is designed to protect your inbox from unwanted messages, but unless your system is properly trained even the best software misses the mark and flags legitimate messages as spam. These messages are referred to as “false positives.”

While consumer and ISP anti spam products focus on blocking messages and even consider some false positives acceptable, businesses require anti spam solutions that treat their messages as very valuable. Failing to receive critical messages in a timely fashion can do irreparable damage to customer and partner relationships and cause important orders to be missed, so eliminating false positives while maintaining high anti spam accuracy is paramount to any enterprise anti spam solution.

What causes false positives?

Different anti spam solutions utilize different methods of detecting and blocking spam. Anti spam software typically uses content filtering or Bayesian Logic, an advanced content filtering method, to score each email, looking for certain tell-tale signs of spammer habits such as frequently used terms like “Viagra” or “click here.” Other anti spam solutions reference blacklists and whitelists to determine whether the sender has shown spammer tendencies in the past. A false positive can occur when a legitimate sender raises enough red flags, either by using too many “spam terms” or sending from an IP address that has been used by spammers in the past.

Minimizing False Positives

Although it takes a person only a moment to process a message and identify it as spam, it is difficult to automate that human process because no single message characteristic consistently identifies spam. In fact, there are hundreds of different message characteristics that may indicate an email is spam, and an effective anti spam solution must be capable of employing multiple spam detection techniques to effectively cover all bases.

A comprehensive anti spam approach involves examining both message content and sender history in tandem. By using a reputation system to evaluate senders based on their past behavior, a more accurate picture of their intentions and legitimacy can be discerned, and a solution’s false positive rate can be further lowered. Has the sender engaged in spamming, virus distribution or phishing attacks in the past? If not, the likelihood of their message getting past the email gateway just went up, and the chances of a false positive declined accordingly. If they have, an effective reputation system knows and flags the message.

Self-Optimization

In order to be most effective, anti spam solutions must learn based on a recipient’s preferences. While most of us prefer not to receive emails containing the term Viagra, some medical organizations might need to receive these emails in order to process patient data. In order to best learn your organizational preferences, anti spam solutions should put filtered emails into a quarantine that allows users to review and make decisions as to whether a particular message is spam. Making this quarantine available to the end-user lowers the administration costs and increases the accuracy of the anti spam system.

Each time a user makes a decision about whether a particular email is or is not spam, the system becomes more personalized and intelligent about filtering email for that individual in the future. Over time, users find that they rarely need to review their quarantines anymore because the system has learned how to identify messages that are important to that user.

Don’t throw the baby out with the bathwater

In conclusion, it is imperative that false positives be kept to an absolute minimum for business users. Although consumers may have more patience with incorrectly blocked email, businesses cannot afford these types of problems. An effective, accurate anti spam solution aggregates multiple spam detection technologies, combining the benefits of each individual technique to stop spam while minimizing false positives. It also puts suspected spam into a quarantine that is available to end-users, and learns how to better identify spam in the future.

About DNS Records

Posted by benz | Posted in Anti Spam Appliance Articles | Posted on 31-08-2010

Being a global, hierarchical and distributed host information database, the Domain Name System, or DNS, is one of the most fundamental building blocks of the Internet.

The most basic function of the DNS is to find the corresponding IP address for a domain name. This service is invaluable for users as domain names are much easier to remember than their corresponding numerical IP addresses. The DNS also makes it possible to assign domain names to groups of Internet users in a meaningful way, independent of their physical locations. Due to this, hyperlinks on the World Wide Web and contact information on the Internet can remain consistent and constant. Many other invaluable services, like routing e-mail to its proper destination, are performed by the DNS.

To understand the field of DNS management, it is very important to learn about its basic data element – the Resource Record (RR).

When sent over an IP network, all RRs use the common format specified in RFC 1035. The NAME field consists of the fully qualified domain name of the pertinent node. TYPE contains the type of RR in numeric form and gives a hint of its intended use. For example, the MX record specifies the mail server used to handle e-mail for a specific domain. CLASS has the class code while TTL contains the unsigned time in seconds till when the RR stays valid. RDLENGTH contains the length of the RDATA field (RDATA is data of type-specific relevance like the IP address for address records and priority and hostname for MX records).

The types of RRs are many. Let us look at some of the most common ones.

The A record is an address record most commonly used to map domain names to their respective IP addresses. CNAME creates an alias of a name and prompt the DNS to retry the lookup with a new name. Similarly, a DNAME creates an alias for a name as well as all its sub-names. LOC specifies a geographical location associated with a domain name while the MX record maps a domain name to a list of message transfer agents for that domain. TXT was originally used for arbitrary human-readable text but now carries machine-readable text more often.

The criticality of the DNS system has prompted most IT managers to scourge the market for robust DNS solutions. A DNS appliance that offers centralized domain and database management, data integrity verification, auditing and diagnostics as well as enables ease of integration with third-party software should fulfill the DNS management requirements of your enterprise.

Stop Excessive Sweating With Your Doctor’s Help

Posted by benz | Posted in Anti Spam Appliance Articles | Posted on 30-08-2010

Whatever you do…

Don’t Be Embarrassed To Talk To Your Doctor About Armpit Sweating and Hyperhidrosis!

They’ve heard it before and will hear it again. Actually, they’ve heard much worse than that (safe bet).

The main idea of this article, what we really want you know, VERY important:

It is absolutely crucial to work consistently with a medical doctor (the Doc) to help treat armpit sweating and hyperhidrosis.

Then we’ll talk about treatments that the Doc’ll probably dole out to ya’. We’ll provide an original Bye-Bye article about each of the excessive sweat treatments.

(Yea, we’re good.)

So without further ado…

Why is it Important to Work Consistently With a Good Doc?

First off, it’s always a good idea to get professional help with important issues. Second, chances are the Doc’ll give you treatments that stop (or at least reduce) excessive armpit sweating. Third, (and most importantly) if the Doc can’t give you something that works, they’ll be willing (and able) to vouch for you that nothing has worked to stop your sweating.

Why Would I Need a Doctor to Vouch For Me?

There are a few standard treatment for excessive armpit sweating that are usually covered by insurance (prescription antiperspirants and oral medications for hyperhidrosis). These work for most people to stop excessive sweating.

But if they don’t work, you’re going to want to try other things. Like possibly botox (which works really well, by the way). But the only problem is, botox is typically considered a “cosmetic” or “elective” procedure, and is rarely covered by insurance.

There’s also a bunch of other “alternative treatments” that are considered elective or not a “medical necessity” and not covered by insurance. Things like acupuncture and hypnosis for hyperhidrosis have also cured excessive armpit sweating for many. But they’re kinda expensive (and not covered by insurance).

That’s no big deal if you’re made out of money. But if you’re like most people, you’d probably like to shift some (or all) of that bill to the good-ole’ insurance company.

So if you’re working with a good Doc, and they can vouch for you that you’ve tried all the traditional treatments for hyperhidrosis to no avail, then these “alternative treatments” can become a “medical necessity.”

Once it is determined to be a medical necessity, then the insurance company will fork out some dough.

So What Type Of Doctor Should I Go To?

You don’t have to go to a dermatologist! Not unless ya’ want to… Most general physicians will have everything you need to treat excessive sweating.

Even if you have a very extreme case of armpit sweating, you’ll probably be just fine with a regular Doc.

Obviously Speed Stick, Old Spice, and Degree just don’t cut it. If you’re like most people with excessive armpit sweating, you’ve probably tried every deodorant/antiperspirant you could get your hands on.

If you haven’t tried a more powerful over-the-counter antiperspirant, now would be a good time to do that.

They have worked for many fellow-sweaters.

If those don’t work for you, there are some more powerful solutions for excessive sweating armpits.

So What’s My Doctor Going To Give Me?

The first arrow in the Doc’s quiver will be a prescription strength antiperspirant.

There are a bunch of different brands of these prescription antiperspirants. One of the more common ones is called Drysol. It consists of about 20% aluminum chloride as it’s active ingredient.

Click here to read about Drysol and other prescription antiperspirants

Some people respond better to over-the-counter antiperspirants for hyperhidrosis than they do to prescription antiperspirants. So a little experimentation may be in order for you.

This leads right into what we say over and over…

Everybody’s Different.

The more you experiment with different excessive sweat solutions, the sooner you’ll learn what works for YOU.

That’s our main goal: To find out what stops YOUR armpit sweat and hyperhidrosis.

This of course requires patience…An indispensable quality in your quest to stop underarm perspiration.

Whatever you do, keep following Mechanic Method (what’s this?).

Implement MM1: Body and MM2: Mind and be consistent with them for at least three weeks. I absolutely dare you to do this and see how it reduces or totally stops your excessive sweating. Mechanic Method is a natural and permanent cure for hyperhidrosis.

But the challenge is staying consistent. Are you up for the challenge?

Please be aware…

Nothing is going to change overnight. Even going through the Doc is going to take patience and consistence to stop armpit sweating.

Is There Any Light At The End Of The Tunnel?

Yes, there absolutely is.

A majority of excessive underarm sweating cases (~65%) are resolved with prescription antiperspirants.

Other Things The Doc May Try

If the prescription antiperspirants don’t stop your armpit sweat, there are also several oral medications prescribed to cure underarm sweating. Some people have success with oral meds, but most people report that the side-effects are too disruptive.

A third, newer method that your doctor can help you with is botox for armpit sweating. We never did try this personally, but it supposedly works really well. Couple things–it is kinda expensive (unless you get your insurance to cover it), and it also hurts a little.

New methods of treating hyperhidrosis are constantly being created and tested. As we research and learn more, we’ll post for you.

Remember…

Excessive armpit sweating and hyperhidrosis is cured and prevented through a systematic process. Follow the steps of this process carefully.

Take Massive Action. Be patient and consistent (can’t stress those two qualities enough).

The results you want and deserve are guaranteed to come!

Ten Easy Ways to Boost Your Computer Security

Posted by benz | Posted in Anti Spam Appliance Articles | Posted on 29-08-2010

These days it is very easy to take our computers for granted. It is almost as if they are part of our office or household furniture. However, we all have increasing amounts of sensitive data stored on our computers and it’s worth being aware of the ongoing risks so here we take a look at the best ways to maintain and improve your computer security.

Of course adding some computer security features to a pc costs a little extra money, but it is essential to do to ward off attacks from the rogues out there determined to upset home pc users as well as large scale organizations. Viruses can vary in seriousness such as harmless but annoying e-mails or spam to programs delivered to PCs that can wipe out all the data stored on the computer.

Let’s take a look at ten ways all of us can improve our computer security:

1. Password Protection – A good start to computer security is to put in a barrier to unauthorised users of your computer. Protect your login id with a password. That way you can ensure that only you can access confidential information on your computer. Never disclose your passwords to other people, don’t write them down and try and make them unique with a combination of letters, numbers and other characters.

2. Operating System – Keep your operating system updated frequently. Turning on the auto-update in Windows Update will boost your computer security. Microsoft releases frequent fixes to vulnerable areas of computer security so this is critically important.

3. Anti Virus Software – Ensure your pc has up to date anti-virus software installed. This is a key element of computer security and will help detect and remove viruses as well as block spam e-mails.

4. Firewall – At the same time your computer security should be enhanced by adding a firewall especially if you are part of a network either at work or home. The firewall setting on your router should be switched on as these could leave you exposed to hackers or indeed your neighbours might be able to view what you are doing on the internet.

5. Regular Scans – Your anti-virus software may do regular background checks, but it is a good idea to run a scan at least once a week. This will help clean up your system by deleting unwanted cookies and temporary internet files.

6. E-Mail Attachments – Be very wary of attachments to e-mails sent to you, especially if they are from an unknown source. These could potentially carry a virus that will prove damaging to your computer. A good computer security tip is to ignore attachments from unknown sources and delete the e-mail. You can save any attachments or downloads to your desktop and scan them with the anti-virus software.

7. E-Mail Links – It is best not to visit websites by clicking links attached to an e-mail. Most links taking you to a home page asking for log-in or account details are scams. Any details entered here can be used by the hacker who set up the link.

8. Suspicious E-Mails – Ignore e-mails that look suspicious and delete them as these could breach your computer security. Ignore any e-mails purporting to be from your bank or someone else you hold an account with asks for personal details or passwords. This breach of computer security is sometimes known as phishing.

9. Websites – Be wary of websites you wish to enter. Some anti-virus programs offer warnings next to websites to indicate whether they can be trusted. Avoid clicking on a website if it is not rated as trustworthy.

10. Online Payments – If you need to make a payment online ensure that the payment screen is protected. The page will usually indicate that it is secure and may have a padlock image at the top of the page.

Anyone still not convinced may want to bear in mind some of the facts about viruses. In January 2007 a worm called Storm appeared on the scene. Nine months later it was believed that some 50 million computers had been infected by the worm. Computer security is so important to protect you and your personal data.

Batteries

Posted by benz | Posted in Anti Spam Appliance Articles | Posted on 28-08-2010

First of all let’s clear up what kind of batteries there are. According to the substances and technology used to produce the batteries – there are lead acid batteries, lithium and lithium ion batteries, nickel cadmium batteries and nickel metal hydride batteries. Certainly there plenty other battery types but the above mentioned are very prevalent and mostly used ones.

Lead acid batteries are really great. These batteries are used to power cars, computer data stations, forklifts and other products which need a high power output. These batteries are not suitable for smaller products as the battery has been designed to work in situations which require lots of energy. As most batteries have been given certain corresponding letters such as double “A” batteries, you will find that a lead acid battery is given the signature letter of A. So if you see an item that requires the use of an A battery you will know that you need to have a lead acid battery for that appliance to work. There are currently two main types of this A battery. These batteries are for instance useful in times when the power has for various reasons been cut off. At these times the lead acid battery can be used in emergency lights to provide the lighting that is needed.

Lithium and lithium ion batteries are great providers of instant power. The general use for a lithium battery can be found in the general consumer products like portable radios. These batteries are also used in powering hybrid electric cars and normal electric cars too. The items which are generally powered by lithium ion batteries include calculators, walkmans, radios, torches and even touch lamps. Even though the batteries for these appliances can vary in size there is one similarity. While you can buy a number of different batteries for your various appliances you will find it more economical to buy a battery that can be recharged to full power.

To help cope with the demands which these organizations might put the lithium ion batteries through there has been a newer version which has been developed. This new lithium ion battery is called a lithium polymer cell. To make sure that the lithium ion battery can be used by a variety of appliances you will find that the battery is made in a number of different sizes and shapes. While the usual use for lithium ion batteries is consumer electronics you will find that you can use these batteries in hybrid electric cars and normal electric cars.

You will find that when you are using a nickel cadmium battery that this popular battery is that of a rechargeable one. You can in general find that these batteries are also known as NiCd – otherwise known as Ni Cad batteries – batteries. There is however an interesting fact which is very seldom thought of. While the consumer battery is called by many of us as a NiCd battery there is yet another battery which uses this name as well. The nickel cadmium battery comes in two forms. These forms are the sealed and vented forms. The general use for a nickel cadmium battery is that of toys and electronic products like walkmans, Discmans and portable radios. There are also specialty nickel cadmium batteries which are available. These batteries are perfect for using in model airplanes, wireless phones, power tools, cordless power tools and even for camera flashes. As you see there are many devices which can use a nickel cadmium battery.

Unfortunately unlike other batteries the nickel cadmium battery is more expensive. This means that unless you are willing to pay more for this battery you may find the other battery brands to be a better buy.

Another type of battery is that of a nickel metal hydride battery. These batteries can be used in appliances where you need long lasting power. You should however make sure that the appliance you need these nickel metal hydride batteries for can work. You will need to find out from the information that is supplied with your appliance if it has this capability. There is one item that you will need to remember about using these batteries. The abbreviated form of nickel metal hydride batteries is NiMH. This battery has the potential to last about three to four times longer than the NiCd batteries. Now in addition to being used in your usual consumer electronic products these batteries can be used for other applications. At present the use of nickel metal hydride batteries can be found in ASIMO by Honda. ASIMO is the human prototype robot. One of the better aspects to be found in using these nickel metal hydride batteries is that they are less detrimental to the environment as compared to some of the other batteries like NiCd batteries. And when it is time to dispose of these batteries you will find that there are recycling programs which can help to safely dispose of the harmful matter in the batteries before a brand new battery is made.

Now let’s talk about the various devices that use batteries to get power. All of these devices are well known, we use them almost everyday without even thinking of using the batteries too. Why don’t we start with watch batteries? The range of watches that you will find is enormous. With most of these watches the popular form of power is that of watch batteries. These watch batteries in general will not have any brand names attached to them. You will find that watch batteries come in different sizes. These sizes are generally based on the watch itself. The usual instance to get a new watch battery is when your watch is running low. At this point you will need to take your watch to a watch smith and get them to replace the watch battery. As watches come in different sizes you will find that it is possible to replace these larger sized batteries without any need for special tools. The larger sized watches can use watch batteries which are double A or triple A sized. You should however make sure that you know the battery size before you buy your replacement batteries.

In general you have two options available for powering the notebook. One option is that of the mains power and the other is that of notebook batteries. You will need to make sure that when you are planning on working with notebook batteries that you know the maximum amount of time that these batteries will power the notebook. To help you get the best power from notebook batteries you will be able to choose from a variety of different ones. These many different batteries will come in slightly different prices but on the whole you should have no problems with purchasing any of these batteries. One of the key items that you should look into when you are thinking about buying replacement notebook batteries is how long these batteries that you are looking into buying will last. In general you can expect notebook batteries to last anywhere from a few hours to half a day. The time length that these batteries last will depend mainly on the functioning of the notebook. The more you use high power consuming functions in the notebook the more power drain which is experienced by the batteries. This means that the notebook batteries will need to be chosen with the tasks that you are going to be engaged in. You will need to do some shopping to find notebook batteries which will provide you with the time limit that you need and an affordable price.

Batteries are also used in cars and motorcycles to start the motor. Those car and motorcycle batteries are really powerful ones. The fully charged new car battery will provide the power that is needed in order for your car to work in any type of weather. When the time comes to replace the car battery the best place where you will find these batteries is in car supply shops. These places will have experienced sales personnel who can help you by showing you the various types of batteries which are on sale. Among these is that of a car battery. Even though we seldom think about the performance of our new car battery we get behind the wheel of the car and expect to go on a journey without any problems. As each car is made according to different specifications you will find that these vehicles have different needs. Therefore it is only sensible that you buy a new car battery which will provide you with the power that you need. While there are many brands of car batteries available you will need to look around before you find the best car battery that you can find and afford.

Now even though motorcycles are popular forms of traveling it is best if you have fully charged up motorcycle batteries for the long distance journeys. You will find many different brands of these motorcycle batteries to buy. The one that you choose will need to be bought with an eye to the future. For instance you will notice that most of the motorcycles are ones that use a lot of power. There are also motorcycles which travel long distances. These touring bikes need to have motorcycle batteries which can be used for long distances before they give out. You will need to make sure that you are choosing a battery that you can afford. This point is important as you may need to look for reputed dealer. The knowledge and experience of well trained dealer you will find that you are getting a good deal on your choice of motorcycle batteries.

Most of the cell phones use cell phone batteries. These cell phone batteries in general will not have any brand names to them. You will find that these cell phone batteries have different sizes. These sizes are based on the cell phone itself. As cell phone technology advances you will find that the cell phone batteries come in different sizes to accommodate these new phone sizes. You should make sure that you know what sort of battery your cell phone takes. This will make buying replacement batteries easier. Now even though it is possible to replace your cell phone with a well working battery you should still take the time to figure out why the battery has died on you. This will allow you to make sure that you don’t make this sort of error happen again. While your cell phone may look sophisticated the battery is very delicate. For this reason you should take care when you are using your cell phone. While technology advances at a furious pace there are still some items in our world that need a helping hand from us. These items like cell phone batteries need to be treated as if they are made from glass. By looking after them in this manner you will be assured that you have a cell phone where you will not have to worry about replacing the cell phone batteries that quickly.

Listen Up! Exposure to Loud Noise May Cause Tumor & Other Health Risks

Posted by benz | Posted in Anti Spam Appliance Articles | Posted on 26-08-2010

Bob Seger, Jeff Beck, Sting, Eric Clapton, Peter Frampton and Bob Dylan all have something in common. Their years of hard rocking have left a mark on more than just their fans — after years of exposure to loud noise, they all now have hearing impairments.

But these hard rockers are not alone. Exposure to excessive noise is, in fact, the most common cause of hearing loss and the most common work-related disease.

Some 10 million Americans already have permanently damaged hearing from loud noise. Another 30 million are at risk right now in their homes, workplace and recreational settings, according to the National Institute on Deafness and Other Communication Disorders (NIDCD).

Surprisingly, though, hearing loss is only one health risk that arises from loud noise exposure. There are several other, serious, risks as well.

According to Eddie Chandler, a stress management specialist, ” … Sounds can literally make you sick. Noise pollution can increase your stress levels and create severe tension in your daily life. It can increase your heart rate, raise your blood pressure and even result in insomnia.”

Acoustic Neuroma Tumor

A study to be published in the February 2006 Journal of Epidemiology found that several years of repeated exposure to loud noise increases the risk of developing a non-cancerous tumor that could cause hearing loss.

People exposed to loud noise were 1.5 times more likely to develop the tumor, called acoustic neuroma, than people who weren’t exposed to loud noise on a regular basis.

The slow-growing tumor gradually presses the cranial nerve that senses sound and helps with balance. Symptoms, which typically become noticeable at age 50 or older, include hearing loss and ringing in the ears (tinnitus).

Noise Increases Heart Attack Risk

Prolonged exposure to high noise levels also increases the risk of a heart attack, according to a study published in the European Heart Journal.

The study involved 4,000 people who had been admitted to Berlin hospitals from 1998 to 2001. When it came to environmental noise (heavy traffic, machines like lawn mowers, yelling kids and barking dogs), it was found that:
Men who were exposed for a prolonged length of time had a 50 percent higher risk of heart attack than those not exposed. Women who had been exposed to noise had a three times higher risk.

“We feel that, if you have a higher and longer exposure to noise, either environmental or workplace noise, you are at a higher risk for a heart attack,” said lead investigator Dr. Stefan Willich.

Risk of High Blood Pressure Goes Up

Another study by University of Michigan researchers, published in the Archives of Environmental Health, found that working in a loud environment raises blood pressure levels.

They outfitted workers at a Midwest auto-assembly plant with monitors to take blood pressure readings and record noise levels throughout the day.

It was found that while blood pressure was affected by overall noise exposure, peaks in noise affected heart rate. Also, an increase of 10 decibels in average noise exposure resulted in a systolic blood pressure increase of 2 millimeters.

To put things in perspective, reducing systolic blood pressure by 6 millimeters (for the long-term) has been associated with a 35 percent to 40 percent reduction in strokes and a 20 percent to 25 percent drop in coronary disease.

Where is All This Loud Noise Coming From?

Noise from all over — work, traffic, music, TVs, industry, people and more — exists like never before. As a result, much of the population is now experiencing related hearing loss and other problems.

“There’s no question that baby boomers have been exposed to different sources of noise than any generation before them,” says Dr. James F. Battey Jr., director of NIDCD. “We’re certainly seeing people in their 40s and 50s who notice their hearing is not as good as it used to be.”

Younger people are also at risk of future problems, as exposure to noise via earbuds or headphones attached to MP3 players and other media devices is common.

Many people may not even realize that they are listening to music at harmful levels. An April 2005 study by National Acoustics Laboratories in Australia, published in the International Journal of Audiology, found that 25 percent of people wearing headphones who were stopped on city streets were listening at damaging volumes.

“Safe” Noise Levels

A safe average of noise for a 24-hour day is 70 dB, according to the U.S. Environmental Protection Agency. Any noise that reaches 85 dB or more can damage your hearing, but even a softer noise can harm your health if it keeps you up at night (a 45-dB noise is loud enough to keep the average person awake) or irritates you.

To put things into perspective, here’s a list of some common noise measurements:

Internet Security – How to Protect Your Computer

Posted by benz | Posted in Anti Spam Appliance Articles | Posted on 25-08-2010

There are several ways on how you can protect your computer from all the Internet viruses and worms that are continuously growing and making its way from website to website.

When we talk about Internet Security, we are basically talking about protecting your computer data-files, passwords, and all other contents-from being penetrated by outsiders through the use of the Internet.

The Internet-being a worldwide connection where anyone can access-is still a very unsecured & easily manipulated technology, that should not be taken for granted. There is an alarmingly growing number of crimes related to the World Wide Web. With that, no one is 100% assured, but with a well-built Internet Security, your worries can be largely minimized because you can be assured that you are well protected from common threats related to Internet problems.

Internet Security can pose itself in different ways; most common are those available in the market that can easily be purchased and downloaded like Anti-viruses and Anti-spywares.

Antivirus programs work by detecting & eliminating viruses that has penetrated your computer. This is very useful in protecting your computer system from malwares. Antivirus programs are programs downloadable from the Internet. There are many programs that you can choose from-some better than others-so careful selection is a must. It is also important to purchase from trusted providers due to websites that offer “protection” but instead provide otherwise.

Anti-spyware program on the other hand protect your computer from spyware’s & adware’s. Spywares being that steals data from your computer to another computer while adware’s are those that automatically displays & downloads advertisements to your computer. Anti-spyware programs are also available through different downloadable software’s found in the Internet. Like Antivirus programs, Anti-spyware’s should also be well selected; licensed and legal websites should be segregated from malicious and fraudulent sites that offer corrupted software’s.

Internet Security may also pertain to E-mail Security-E-mail being a very important part of the Internet. There are a lot of Malwares that link itself to & circulate through to E-mails. When talking about E-mail malwares, it’s important that we give a brief discussion about Spam‘s. Spam‘s are e-mails that are directly segregated from your usual e-mails, spams are those found to be linked from unsecured sources like advertisements. Not all unsecured e-mails are segregated though, that is why it’s important not to release your information & e-mail addresses to any network, because once E-mails that carries with it viruses and malwares are opened, penetration is already inevitable, and that’s how a lot of famous malwares were able to circulate itself.

Choosing browsers can also help tighten your Internet Security. As of 2009, there has been a significant drop in Internet Explorer users because of the growing security problems linked to the browser; likewise is the growing number of consumers of Firefox, Safari, & Google chrome.

Still, the most important thing to consider when securing your network from Internet Malwares is that you visit only trusted and safe websites. Protecting your network starts with you.

Winning the War On Spam

Posted by benz | Posted in Anti Spam Appliance Articles | Posted on 25-08-2010

For years I didn’t worry much about spam.

But lately it’s got out of control. Over half of my email

is now spam, and it was growing by the week – until I took

action.

This article shows you some strategies for winning the war

on spam.

————————————————

How Do They Get Your Address?

————————————————

In the old days, spammers got their addresses mainly from

Newsgroups – if you didn’t post to Newsgroups, you were

reasonably safe. But they’re now using a much more

efficient method to build their lists – email harvesters.

Email harvesters are robots that roam the Internet

collecting email addresses from web pages. Examples are

EmailSiphon, Cherry Picker, Web Weasel, Web Bandit and

Email Wolf, to name just a few.

How can you protect yourself from email harvesters?

By ‘munging’ (mung = ‘mash until no good’) or cloaking your

email address.

There are many ways of munging your address – the easiest

technique is to use ASCII code for the punctuation in your

email address (instead of symbols).

For the colon after mailto use : and for the @ symbol

use @ and for the period use . . With this method,

your email address would become:

mailto:yourname@yourdomain.com

but it will display as:

mailto:yourname@yourdomain.com

Your email address will appear exactly as it did before,

and it will still be ‘clickable’, but email harvesters will

ignore it and move on.

There are also JavaScript’s that you can insert into your

web page that will make your email address visible to

humans but invisible to harvesting programs. Here’s one

that works very well:

How To Fight Spam

—————————–

The most important thing is never, ever, reply to spam.

Most spam contains an innocent-looking ‘remove me’ email

address. Do not use it. Here’s why:

Spammers typically buy a CD containing a million or so

email addresses, but they have no idea how many of those

addresses are active. So before beginning their marketing

campaign in earnest, they send out a ‘test message’ to the

entire list.

The test message contains an email address for removing

yourself. When you reply to that address, it confirms to

the spammer that your address is active and therefore worth

spamming.

Worse still, the spammer may be distilling from that CD a

list of confirmed active addresses that he will then sell

to another spammer.

The key to dealing with spam is to report it to a 3rd

party: (1) the affiliate program that the spammer is

advertising, (2) the spammer’s web host, or (3) the ISP the

spammer used to connect to the Internet.

When you report spam to a 3rd party, remember to be polite

- they didn’t send the spam and they’re probably just as

anti-spam as you are.

(1) Reporting to Affiliate Programs

Many spammers are affiliates advertising someone else’s

products or services. So look for a website address that

contains an affiliate link, something like this:

[http://www.affiliateprogramdomain/841526]

Then just send an email to the affiliate program

(abuse@affiliateprogramdomain.com), informing them that you

are receiving spam from one of their affiliates.

Most affiliate programs have zero tolerance for spamming

and will remove an affiliate spammer without warning.

Now, affiliate spammers don’t want you to see their

affiliate link, so many of them send their email as HTML.

All you see in the message are the words ‘Click Here and

Order Now’.

But in your browser just click on ‘View Source Code’ and

search for the letters ‘http’. That will take you to the

spammer’s affiliate link.

(2) Reporting to Web Hosts

If the spam doesn’t contain an affiliate link, it’s likely

that it is coming from the owner of the domain name. In

that case you’ll have to report it to the spammer’s web

host or their ISP.

To make a report to the spammer’s web host just go to

Whois, the directory of registered domain names:

http://www.netsol.com/cgi-bin/whois/whois

Type in the spammer’s domain (the website address that

appears in the spam) together with the extension (.com,

.org, .net etc).

The host for that domain will usually be listed as the

Technical Contact in the Whois record and there will be an

email address for contacting them.

(3) Reporting to ISPs

To report a spammer to his Internet Service Provider,

you’ll have to look at the spam‘s ‘extended headers’.

Extended headers show the servers that the message passed

through in order to get to you. The instructions for

viewing extended headers will vary depending on what email

client you are using.

=> In Pegasus Mail, open the offending message and then

right-click and choose ‘Show raw message data’.

=> In Eudora Light, click on ‘Tools’ in the top menu

bar, and then ‘Options’, and then select the

checkbox option that says ‘Show all headers (even

the ugly ones)’ and click OK.

=> In Outlook Express, open the offending message,

select ‘Properties’ from the File menu and then

click the ‘Details’ tab.

Reading and understanding extended headers is quite a

detailed subject. Here’s an excellent free tutorial on how

to decipher extended headers:

http://www.doughnut.demon.co.uk/SpamTracking101.html

As an alternative to these reporting techniques, you could

use a web-based spam reporting service such as SpamCop

(www.spamcop.net). SpamCop deciphers the spam‘s message

headers and traces the mail back to its source.

Wishing you every success in the fight against spam!
