Protecting from Spam

Spam is flooding the Internet with many copies of the same message, in an attempt to force the message on people who would not otherwise choose to receive it. Most spam is commercial advertising, often for dubious products or get-rich-quick schemes. Spam costs the sender very little to send most of the
costs are paid for by the recipient or the carriers rather than by the sender.

Never respond to spam
Most of spammers say in their mail to unsubscribe click here but they’re lying. What they really want to do is confirm that they’ve got a live address. Also, if the user respond, they’ll sell their addresses to every other spammer meaning user soon be flooded with even more spam.

User should not post his address on his website
It seems like a good idea at the time, but posting an email address on a personal home page is just an invitation to spammers. Spammers and the people who sell spamming as a business have software that "harvests" email addresses from the Net. This software crawls through the Internet seeking text strings that
are username@domainname. When it finds one, it catalogs it on a database of other email addresses to be used to send spam. It is recommended that instead of giving e-mail in text form at the website, user should give an image of it.

Use a second email address in newsgroups
Newsgroups are the great email address gathering ground for spammers. If someone posts to a group, he is going to get spam it is just a matter of time. So how is he supposed to participate? Use a different email address for talking to friends and relatives. In other words, have a public address and a private address.
One has to deal with spam only on his public address.

Use a spam filter
While there is no such thing as a perfect filter, anti-spam software can help keep spam at manageable level. Some of it is cumbersome, some works better than others, some even requires that the user let his email messages go through another system for storage and cleaning.

Never buy anything advertised in spam
The reason that people spam is because they can make money. They make money, like all advertisers, by convincing people to buy a product. If no one buys the things advertised in spam, companies will quit paying spammers to advertise their products.

Disable scripting features in e-mail programs when possible
Since e-mail programs frequently use the same code as web browsers to display HTML formatted messages, the vulnerabilities that affect ActiveX, Java, and JavaScript are often applicable to e-mail. Apart from disabling these features, the ability to run Visual Basic Scripting (VBS) should be removed if possible.
Viruses such as I LOVE YOU contain attachments ending in .vbs which infect the host when user clicks on the attachment to open it.

Protection from Phishing Attacks

When user receives an e-mail asking him to visit his bank’s web site, it signifies the beginning of a phishing fraud. The e-mail would usually provide a link to bank’s web site and ask the user to click the link. It would ask him to provide certain confidential banking information like his account number, credit card number etc., failing which his account would be doomed. There would be a sense of urgency and panic in the e-mail. This type of attack is called as phising attack.

Here is a checklist which helps to prevent this type of attack:
Check to see if the e-mail is indeed from the user’s bank and not from just any bank. If it isn’t, stop reading further and confirm the same from the by using other means like telephone. If the e-mail is not personally addressed to the user, it is most probably a fraud. Check the language and spelling of the text contained in the e-mail. If the user find misspelled words or substandard language, conclude that it is not from his bank.
If the e-mail urges the user to act immediately without delay, failing which his account will be closed down, stop reading it. It is not from user’s bank. If there is anything that even remotely feels wrong, stop. If something feels wrong, it is most probably wrong. Never click any link given inside the e-mail message. Instead, directly type the URL of the financial institution. If the user does not know the URL of his bank’s web site, take the time to call them immediately to find out. User should never provide personal information to anybody, come what may.
 
Do not visit untrusted websites
It is always recommended that the user should not visit the untrusted websites or download software’s, screensavers or games etc from those untrusted sites. There is a possibility that these types of application software install some kind of malicious code on the user’s system, which can be used to launch attack
on other computer systems without any consent of the user.
