There are a few steps to effectively manage SSH keys:
1. Create a strong passphrase for the private key: When creating or generating an SSH key pair, ensure that the passphrase is strong and unique to protect the private key from unauthorized access.
1. Limit access to the private key: Only authorized individuals should have access to the private key. The private key should be kept in a secure location and should not be shared without proper authorization.
1. Use different SSH keys for different purposes: It’s recommended to use different SSH keys for different purposes, such as one for personal use and one for work-related activities. This helps to prevent any potential security breaches from spreading across all your accounts.
1. Rotate SSH keys regularly: It is advisable to replace SSH keys on a regular basis, especially if the key has been compromised or if an employee leaves the organization.
1. Use a key management system: A key management system can help to centralize and automate the SSH key management process. Such a system can also help monitor key activity and identify any unauthorized access attempts.
1. Monitor SSH key activity: Regularly monitor and audit SSH key activity to detect any unusual or suspicious activity. This can help to identify and prevent potential security incidents.
