![]() ![]() Here are examples of these common configuration settings that reduce security risks:ĭisabling password-based authentication - choosing this configuration makes brute-force password attacks impossible.ĭisabling root account remote login - This prevents users from logging in as the root (super user) account. ![]() In most organization system administrators can disable or change most or all SSH configurations these settings and configurations can significantly increase or reduce SSH security risks. Other common SSH vulnerabilities are exposed via configuration and settings. The bad guy gets access to server 1 and then he/she hunts and pecks until they get access to another server and then repeat until they find something interesting/useful. He can then pivot from server 1 to 2, 2 to 3, etc. Very useful right? But imagine if a bad guy gets access to one server. They can then pivot from server 2 to 3, 3 to 4, on and on to perform whatever task they needed to do. They then can pivot from one server to the next without having to logout and the login to the next server. Imagine a sys admin logs into one server and performs a task. ![]() Or what if a malicious actor got a copy of Susan’s keys? Or someone else’s keys? There would be evidence of these things in SSH logs, but only if someone at Susan’s company is monitoring those SSH logs.Īnother very useful capability of SSH and the use of keys is the ability to pivot from one machine to the next. However, if nobody removes Susan’s keys from the servers, she still has access. Susan leaves the company, which doesn’t impact the servers at all. She used SSH keygen to generate keys and she now can login to the systems via Secure Shell. So, imagine Susan is a system admin and she has access to several servers. Īlso, remember how users can use keys rather than a password to login? These SSH keys never expire. ![]() When they become vulnerable bad guys can take advantage of that to do bad stuff. These algorithms change and as they age, they become more vulnerable. Knowledge is power, so let’s look at the most common SSH vulnerabilities so you can be sure your organization is protected from them! When SSH machine identities are properly secured, this can lead to key sprawl, lost keys, lack of policy enforcement, data breach, and much more.
