Security Best Practices - Stopping malware and other threats
Last Updated April 25, 2012
Symantec Endpoint Protection – Best Practices:The threat Landscape has changed and cybercrime is rampant. Companies cannot depend solely on desktop antivirus technology to protect themselves. Following the steps in the tabs below will improve the protection of desktops running Symantec Endpoint Protection and stop malware.
Use IPS (Network Threat Protection)
Threats today are web –based. The Intrusion Prevention System (IPS) in Symantec Endpoint Protection stops threats before they can infiltrate a machine. IPS stops vulnerability exploits, Drive-by-Downloads and Fake AV installation.

Keep browser plugins patched
Attacks have moved to the browser . It’s critical that attackers not be able to use Microsoft® Internet Explorer, or Adobe® Reader/Acrobat/Flash vulnerabilities to get on a system. Use each vendor’s auto update or software distribution tools to install patches as soon as they become available.
Worms love to spread via networked drives. Unless there is a strong business requirement, close mapped drives. If possible limit permissions to read-only rather than read-write.
Review mail security and gateway blocking effectiveness
Catching threats before they get to the desktop can be done with effective mail and web security scanning. Check that you have a mail security solution which updates frequently to detect the latest bad sender IPs, spam and malware threats at the mail gateway. Consider implementing a web security solution that will protect your organization against Web 2.0 threats, including malicious URLs and malware.
Review your security content distribution schedule
Antivirus signatures are released multiple times a day and IPS content roughly on a weekly basis or as needed. If possible, take advantage of these updates or at least update machines that are frequently infected.
Implement application control rules to block specific threats
Symantec Endpoint Protection’s application and device control is a power tool that can be used to stop a specific file, block peer-to-peer (P2P) network use or protect critical files and registry entries.
Most malware attacks use social engineering. Education can be highly effective in stopping them. Your users don’t need to be security experts. Today, just remembering four things can keep them protected.
