Cisco's Annual Security Report found that the overall number of disclosed vulnerabilities grew by 11.5 percent this year, compared to 2007. And if that wasn't bad enough, vulnerabilities in virtualization technology nearly tripled from 35 to 103 year over year. The annual report found that attacks are becoming increasingly blended, cross-vector and targeted.
Cisco said its researchers saw a 90 percent growth during 2008 in threats originating from legitimate domains, nearly double what was seen in 2007. The Cisco report also said spam accounted for nearly 200 billion messages each day, approximately 90 percent of worldwide email.
Despite some signs of progress, this is no time to let your guard down. The Cisco report said to keep on the lookout for the following:
- Insider threats
- Data loss
- Mobility, remote working and new tools as risk factors
