SSH Key-based Host Authentication Configuration in OEM

If we want to schedule or submit a centralized job/patching activity through OEM which is intended to connected to multiple hosts, this setup will help.

Since the SSH credential is set as preferred credentials for the host the agent can now run the commands through the SSH client on the host to perform the requested operations.

 Advantages of SSH Key-based Host Authentication:

  • The encryption used by SSH provides confidentiality and integrity of data over an insecure network.
  • SSH also protects the system against DNS spoofing attacks.
  • SSH was designed as a replacement for FTP, telnet and other unsecure remote shells, which send information, notably passwords in plaintext, leaving them open for interception.
  • This makes ssh a better choice in production environments over telnet/FTP and other username/password based authentications.
