I looked all over Google.com but I couldn't find any answers. I am hoping someone could help me here.
Background Info:
We use a Certificate Authority Server that signs our engineers Public/Private key and issues them a certificate. Our engineers will then use that certificate to SSH into the instances. The Certificate Authority server's public key is distrubuted on all our EC2 instances and SSHD conf is updated to trust a CA and its public key.
All our engineers' SSH as ec2-user and Linux secure logs record the following entry when an engineer SSHs into an instance
Oct 9 20:30:24 awesomelinuxserver sshd[5079]: Accepted publickey for ec2-user from 192.168.7.99 port 12118 ssh2: RSA-CERT ID john.doe (serial 6666669999985847) CA RSA SHA256:uef8+ggsgkJ6kC2Yfadfa+TbZadf28AFY
Problem:
When an engineer su to root the following log is recorded in the secure log:
Oct 9 22:28:35 awesomelinuxserver su: pam_unix(su:session): session opened for user root by ec2-user(uid=0)
Question:
How do I tailor the secure log to record the su escalation as the user's RSA-CERT ID rather than the user? So instead of saying su session opened to root by ec2-user, it should say su session opened to root by john.doe. Has anyone done this before?
