Brute-forcing authentication for SSH

Any service allowing users to authenticate via a username and password can be brute-forced. The term “brute-forcing” refers to systematically attempting all possible combinations of passwords or encryption keys until the correct one is found. This method is used to gain unauthorized access to a system, application, or encrypted data. The attacker tries every possible SSH, SCP, and SFTP username and password or key until the correct one is discovered.

SSH server access control

We can check the SSH server configuration file via the following:

Invoke-Command -ComputerName ssh.snowcapcyber.com -ScriptBlock { Get-Content /etc/ssh/sshd_config }

This command retrieves the contents of the SSH server configuration file. Analyzing this file provides insights into various security settings.

Reviewing user access

We can review the user access requirements via the following:

Invoke-Command -ComputerName ssh.snowcapcyber.com...
