Online Spam: The Major Things You Should Know
Written by kiti SEO on 11.4.08Today, the Internet is reminiscent of the wildest days of the Wild, Wild, West. Your stagecoach through the World Wide Web can be hijacked at any instant if you have no knight in firewall armor to ward off any viral intruders. When your computer is connected to the internet with no firewall running, it is vulnerable to attack from spammers, hackers and phishers.
The ideal firewall will hide the ports that a hacker might use to gain access to your PC and protect your home PC from attacks, as well as track those attempted entries and prohibit unauthorized access or output from your computer. Two-way firewalls are the best as they block the threats that are incoming OR outgoing, to prevent things such s virus, Trojans or malware from being installed without you knowing it.
Spammers harm
Spammers can get unauthorized access to your mail box and aside from constantly inundating your inbox with unwanted email, spammers now pose grave threats to the health of your computer
One of these new dangerous aspects of spam are that illicit senders can now manipulate your email addresses, and make it seem to the rest of the world that the spam that is sent is coming from your personal computer or domain. This may result in your service provider blocking your Internet connection, or terminating your account. And all of it can be done without any knowledge on your part. It can easily be made to seem that you are an actor in a malicious mail campaign when in fact you are an unwitting actor at best.
The purpose of spam is to get your personal and financial information. Often it will fraudulently send you to web sites where this information regarding email, finances, bank accounts or other personal info is gathered and used in illegal ways. Very often, the spammers will combine methods, spamming their victims with virus-laden software, phishing and other schemes that take spam to a whole new level of illicit, criminal activity.
The whitelists
Whitelists are quite possibly the single most effective form of spam protection available on the market today. They are as close as you can get to totally eliminating spam from your inbox.
When an email from an unknown source is received, the system will respond automatically, sending a "challenge" back to the sender. This challenge may require the sender to answer certain questions, or decipher an image that displays a series of letters and numbers. This image can only be deciphered by a human, and not by spamming software. Once this is successfully done, the email is allowed to go through the system to the inbox. The sender is also added to the whitelist. The challenge-response methodology uses a combination of human judgment and software technology to determine which email to let through and which to block.
