info:
|
|
name: SSH Key-Based Authentication - Disabled
|
|
author: pussycat0x
|
|
severity: low
|
|
description: |
|
|
SSH key-based authentication is disabled, allowing password-based logins, which increases the risk of brute-force attacks and unauthorized access.
|
|
remediation: |
|
|
Enable SSH key-based authentication by adding the public key to ~/.ssh/authorized_keys and disabling password authentication in /etc/ssh/sshd_config (PasswordAuthentication no).
