Top 10 Computer Security Threats

1. Malicious spam invades blogs, search engines, forums and Web sites
Websense predicts that hackers will increasingly use Web spam to post URLs to malicious sites within forums, blogs, in the commentary or 'talk-back' sections of news sites and on compromised Web sites. This activity not only drives traffic to the infected Web sites but also assists in the purveyor's site sitting higher on search engine rankings, increasing the risk that users will visit the site.

2. Attackers use Web's 'weakest links' to launch attacks
The Web is an entanglement of links and content. The advent of Web 2.0 additions such as Google Adsense, mash-ups, widgets, and social networks along with the massive amounts of Web advertisements linked to Web pages have increased the likelihood of 'weak links' -- or Web sites and content that are vulnerable to compromises.
