Here a few pointers to prevent your computer from getting infected.
 | Turn off and remove unneeded services. By default, many operating
systems install auxiliary services that are not critical, such as an FTP
server, telnet, and a Web server. These services are avenues of attack. If
they are removed, blended threats have less avenues of attack and you have
fewer services to maintain through patch updates.
| If a blended
threat exploits one or more network services, disable, or block
access to, those services until a patch is applied.
| Always keep your patch levels up-to-date, especially on computers that
host public services and are accessible through the firewall, such as
HTTP, FTP, mail, and DNS services.
| Enforce a password policy. Complex passwords make it difficult to crack
password files on compromised computers. This helps to prevent or limit
damage when a computer is compromised.
| Configure your email server to block or remove email that contains file
attachments that are commonly used to spread viruses, such as .vbs, .bat,
.exe, .pif and .scr files.
| Isolate infected computers quickly to prevent further compromising your
organization. Perform a forensic analysis and restore the computers using
trusted media.
| Train employees not to open attachments unless they are expecting them.
Also, do not execute software that is downloaded from the Internet unless
it has been scanned for viruses. Simply visiting a compromised Web site
can cause infection if certain browser vulnerabilities are not patched. |
