If you encounter an FTP server that allows anonymous read access, but read access is restricted to an FTP directory that does not contain any files that would be interesting to an attacker, then die risk associated with the anonymous read option is minimal. Though FTP is an insecure protocol and we should generally steer our clients towards using more secure options like SFTP, using FTP with anonymous read access does not by itself lead to a compromise. For example, consider FTP anonymous read access.
111 fact even a seemingly harmless misconfiguration can be the nuiiing point in a penetration test that gives up the keys to the kingdom. These may still turn out to be very interesting on a penetration test. When searching for known vulnerabilities you will find more issues that disclose sensitive information or cause a denial o f service condition than vulnerabilities that lead to remote code execution. Note that not all vulnerabilities will result in a system compromise.

You need to conduct penetration testing and list die direats and vulnerabilities found in an organization’s network and perform port scanning, netw ork scanning, and vulnerability scan n in g ro identify IP/hostname, live hosts, and vulnerabilities. Vulnerability scanning is a critical component o f any penetration testing assignment. It evaluates the organization’s systems and network for vulnerabilities such as missing patches, unnecessary services, weak authentication, and weak encryption. Vulnerability scanning determines the possibility o f network security attacks. Scanning a Target Network Scanning a network refers to a set ofproceduresfor identifying hosts, po/ts, and services running in a network.
