Five big security threats for 2011

Ian Paul | March 10, 2011
Online malicious activity was a major headache in 2010, and so far, 2011 is no different: We've seen scams and malware on Twitter, Facebook, and the Android Market, as well as a rise in politically motivated online attacks. But that's no surprise to security experts such as Graham Cluley, senior technology consultant for security firm Sophos. Cluley says that Sophos analyzes about 95,000 pieces of malware every day that is either brand-new or a variant of an older attack.

The hacktivist group Anonymous, for example, grabbed headlines this year for mounting attacks in defense of whistle-blower site WikiLeaks, and attacking government Websites in support of recent protests in Egypt, Tunisia, and Libya. The group also leaked a cache of e-mail messages from a security researcher who was trying to identify Anonymous members. "Whether it's WikiLeaks, Anonymous, or a Chinese or Russian attacker, theft of industrial secrets is shaping up to be one of the key issues of 2011," Jaquith says in a statement.

Protect yourself: If you are trying to safeguard your company's secrets or are worried about data leaks, monitor your company's network traffic for suspicious activity and conduct regular reviews of employee data access privileges.

The Internet may be filled with malware and potential threats, but that doesn't mean you need to panic. Keep your guard up, use common sense, and keep your software up-to-date, and you should be able to reduce your risk of falling victim to attack.
