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.
Because of that fact, they’re often vulnerable to the same viruses and other internet security threats that the average desktop system is. They also need to run antivirus software, firewalls and other forms of protection.
What Other Options Are There?
These servers can be servicing thousands of users at the same time in some cases so they’re a popular target for the virus writers. As a user on these systems, you can help keep them virus-free by making sure your own computer is. And their system administrators can help by limiting what kinds of programs get installed on them.
By keeping your computer protected by antivirus, firewall and other internet security software you help to minimize the target area for the attacks to hit. It can also help to keep your browser and operating system updated with the latest patches, and possibly even run an alternative browser such as Firefox instead of Internet Explorer.
Users and administrators should avoid using bootable CD’s and DVD’s that haven’t been virus scanned after being burned with desired software and files. Sometimes the process that creates them propagates viruses, just as floppy disks did some years ago.
If you use FTP, you should look into switching to a more secure system for file transfers. FTP passwords are sent “in the clear” - there is no encryption on them at all. So when you log into an FTP server, if someone is monitoring your internet traffic, they can easily get your password.
It’s up to all of us to make sure these systems remain secure - not just the system administrators. They have a lot of work on their plate and aren’t always as quick to respond to security issues as they would like.
