The Importance of Protecting SSH Keys
SSH keys provide the highest privileges for accessing servers, applications and cloud instances. If left uncontrolled, SSH keys create significant gaps in privileged security controls. A single stolen SSH private key gives a hacker rogue root access to your network, bypassing all the security controls you’ve put in place.
Why Your SSH Keys May Be at Risk
SSH keys do not expire, creating a perpetual vulnerability if not rotated. Surprisingly, most companies change their SSH keys less often than they change passwords. They rely on system administrators, not IT security teams, to self-police SSH keys. And some do not rotate SSH keys at all.
First, You Have to Know Your Exposure
Without the proper security, you won’t be able to identify how many SSH keys you have, who uses them, and what they can access. This leaves you unable to detect when rogue SSH keys are introduced into your network, let alone detect anomalies in their use.
Create a Baseline for Compliance
Venafi helps you create a comprehensive inventory of SSH keys and their corresponding configuration information. We’ll help you uncover SSH keys that do not meet internal and external compliance standards, and identify lost, orphaned, or unused keys. You can then map the trust relationships between hosts and user groups that are authorized to use the respective SSH keys.
Prepare to React Quickly to SSH Anomalies
After you have created a baseline of SSH key usage, you can detect misuse with real-time monitoring. This lets you act quickly when you see changes to authorized key lists, key additions and deletions, and other suspicious changes.
Notifications and Escalations
Proactive event notifications alert you to specific key events and actions. So you can quickly remediate any anomaly detected and remain in compliance with internal and regulatory policies. You can then change SSH key configurations that do not comply with policy and may indicate malicious activity.
Protect Your SSH Keys with Venafi
Venafi helps you secure the trust established by SSH. Our key and certificate security platform automates SSH key discovery, issuance, and rotation, in turn improving your security and speeding incident response.
