Protecting The Internet From Virus Attacks
These days, most computer users realize they need to be using antivirus software. The trouble is, there is a lot of equipment providing services to these users on the internet. What is being done to protect them from virus infections?
Viruses can attack servers that run websites, email and other internet functions. They’re not limited to desktop PC’s.
Servers are usually substantially the same as PC’s only with more memory, disk space and processors. Web servers house web pages and programs for Internet users, e-mail servers store, send and receive e-mail, and file and ftp servers make possible storage and distribution of all manner of files for other systems. Routers are simply specialized computers, with proprietary operating systems, for routing network traffic.
Most operate much like an individual’s system and are subject to the same kinds of attacks. They can therefore be protected by many of the same means - regular use of reliable antivirus software and being firewall guarded to shut down vulnerable entry points on the Internet.
What Other Options Are There?
Because these servers provide internet services to many users (sometimes thousands at a time) they are a popular target for the people who create viruses. As an end user, you can help to keep these systems virus-free by ensuring that your computer stays that way. And the system administrators on those systems can help by limiting the type of software that gets installed on them.
When you keep your computer protect against online security threats, you’re helping to minimize the target area for hackers. It’s also necessary to keep your computer updated with the latest operating system and browser patches. You may even want to consider running a more secure web browser, such as Firefox, instead of Internet Explorer.
You should also avoid booting from CD’s, DVD’s or USB memory sticks that haven’t been scanned for viruses. If one of the files that was saved on the disk was infected, booting with the disk can cause the virus to spread even faster.
FTP servers, used to store and provide sending and receiving of files over networks, should become a thing of the past. Vanilla ftp (File Transfer Protocol) can’t be secured since passwords are passed in clear text (unencrypted) over the network where they can be picked up by sniffers. Sniffers are software and/or hardware used to spy on networks. Secure FTP versions should be used instead.
Users should take an active role in encouraging administrators to lock down systems. Most admins do a very good job with limited time and resources, but security is usually well down their list of priorities. Users who show an interest can alter that in a constructive way by showing that they care. Very few servers have a thorough check by a skilled security expert at any time in their serviceable lifetimes. That would change if users didn’t passively assume by default that everything is fine until things go sour.
