Top 10 Vulnerabilities

The Top 10 External and Top 10 Internal Vulnerabilities are dynamic lists of the most prevalent and critical security vulnerabilities in the real world. Based on the Laws of Vulnerabilities, this information is computed anonymously from over 1 billion IP audits per year. The Top 10 External Vulnerabilities are the most prevalent and critical vulnerabilities which have been identified on Internet facing systems. The Top 10 Internal Vulnerabilities show this information for systems and networks inside the firewall.

The two Top 10 lists exclude vulnerabilities that do not have patches, even if workarounds are available, because these lists are tools to help prioritize remediation.
