DETECTION OVERVIEW
Risk Factors
SSH is a common target for attackers because it provides remote control access to other devices. Attackers can find weak SSH passwords through low-cost techniques such as brute force attacks or by exploiting SSH server vulnerabilities to bypass authentication. The impact to a business can be low if the connection attempt fails or if the attacker connects to a device with limited privileges. However, these activities should be examined before they facilitate critical and costly attacks.
The system might change the risk score for this detection.
Category
Disable internal services that are exposed to the internet, especially services that run over remote access protocols
Disable SSH unless required
Only allow incoming SSH connections from trusted devices, such as administrator workstations
Block outbound SSH connections unless required
Implement public-private key authentication, which is less susceptible to brute force attacks
