Question

What security actions are considered to be the best defense against a virus like the Slammer Worm?

Answer 1

Answer)

The Slammer worm is the one, which performs denial of service on Internet hosts and slows down the traffic. The worm spreads rapidly and this is the result of a buffer overflow bug in the MS SQL Server and the desktop engine. The security actions, which can be taken to defend against it, are:

Administrators should block the UDP port 1434 as the Slammer work uses thus port. They should download and apply the SP3 from Microsoft for this.

Installed anti-virus and anti-malware on the system, and perform system scanning time to time.

Do not download unknown files, visit unknown links.

Use a personal firewall always to block suspicious traffic.

Perform secure browsing using https.
