Detection & Prevention Virus On UNIX
Detection: Viruses can reliably be detected by using an integrity
shell instead of the normal UNIX shell. Integrity shells for UNIX
have been in use for several years, and work transparently to the
normal user.
Prevention: Viruses can not be completely prevented under
UNIX or any other modern operating system except by
eliminating sharing, or eliminating programming. This is almost
never feasible in a modern UNIX system.
Cure: Viruses are best cured with on-line backups which
automate the restoration of corrupted information under an
integrity sell. Off-line backups are also effective in many cases, as
long as good detection is in place. Without good detection,
backups are ineffective against viruses.
