Internal Vulnerability Assessment using Nessus
Nessus Nessus is an network vulnerability scanner that uses the Common Vulnerabilities and Exposures architecture for easy cross-linking between compliant security tools. Nessus employs the Nessus Attack Scripting Language (NASL), a simple language that describes individual threats and potential attacks. Nessus has a modular architecture consisting of centralised servers that conduct scanning, and remote clients that allow for administrator interaction. Administrators can include NASL descriptions of all suspected vulnerabilities to develop customised scans. Nessus allows scans for the following types of vulnerabilities: Vulnerabilities that allow a remote hacker to control or access sensitive data on a system. Misconfiguration (e.g. open mail relay, missing patches, etc.). Default passwords, a few common passwords, and blank/absent passwords on some system accounts.
