Do's & Dont's in Network Security

Things to do:

Do scan the computer regularly with virus scanning software.

Do scan all downloaded files and e-mail attachments from the Internet for viruses before opening them.

Do switch off automatic processing of e-mail attachments in the Internet e-mail software.

Do scan floppy disks, compact disks and other storage media, especially those of unknown sources, with virus scanning software before use.

Do backup your programs and data regularly. Recovery from backup is the most secure and effective way to recover the lost data.

Do change your NetPassword periodically to prevent password hacking.

Do remember to log out the system, when using computers in public places (computer labs. library, cybercafés).

Do consider using the Anti-Spam Mail System implemented by CSC and define custom filter rules available on your email software. See how to do this in:

Outlook Express Netscape Mail Web Mail
