In the vast ocean of network security, SSH (Secure Shell) stands as a towering lighthouse guarding the data traffic to and from your servers. However, how do you ensure that this lighthouse is in optimal condition? Enter ssh-audit, a tool for auditing your SSH server and client configurations.
Ssh-audit supports SSH1 and SSH2 protocol servers, diving deep into the SSH configurations to grab banners, recognize the software and operating systems involved, and even detect compression settings. It gathers information on key exchanges, host keys, encryption, and message authentication code algorithms, providing a comprehensive report on their status.
Getting started with ssh-audit is a breeze. Clone the repository from GitHub, and with a few commands in your terminal, you’re on your way to auditing your SSH configurations. The tool fetches algorithm information, outputting details such as availability, removal or disabling status, and security strength (unsafe, weak, legacy, etc). Moreover, it provides algorithm recommendations based on the recognized software version, aligning your settings with industry standards.
The icing on the cake? Ssh-audit outputs security information, including related issues and assigned CVE (Common Vulnerabilities and Exposures) list, offering you a clear picture of the security posture of your SSH setups.
With ssh-audit, not only do you get to audit your SSH configurations, but you also receive actionable insights to harden your SSH setups against potential threats. So, the next time you’re looking to bolster your network security, try ssh-audit and sail smoothly in the turbulent waters of cyber threats.
