Top Cyber Security Risks
Source: http://www.sans.org/top-cyber-security-risks/
Priority One:
Client-side software that remains unpatched.
Priority Two:
Internet-facing web sites that are vulnerable.
Operating systems continue to have fewer remotelyexploitable vulnerabilities that lead to massive
Internet worms.
Rising numbers of zero-day vulnerabilities
