Nessus Security Scanner (http://www.nessus.org) for example, is one of the highest rated security/vulnerability scanners as rated by a Network Computing article. It relies heavily on Nmap to perform port scanning. Nmap is Enumeration Tools (Network Scanners). Nmap and Nessus have different types of scanning philosophies and understanding how they work can help you achieve success with your network scanning efforts. The Nessus server includes its own portscanning, service fingerprinting and operating system identification techniques that are similar but independent from Nmap’s. However, you may run into a situation where Nmap was run first and you already have the output from this tool and want to apply the results to your vulnerability scan. Configuring Nessus to run batch mode scans based on Nmap results. |
