Use of an insecure channel - Oracle Database

Description​

Insecure connections from servers to the database. Encryption does not address all communications with the database, including transmissions from clients and transmissions from middle tiers.

Impact​

  • Data can be modified, replayed and no longer confidential. Also, lost packets can be detected.
  • Intercept sensitive information that travels over an intranet.

Recommendation​

  • Set up encrypted communications channels. Enable Oracle Database encryption for data that is sent over a network.
  • Ensure that connections only come from a physically secure terminal, or from an application web server with a known IP address.
  • In the case of a sensitive database, ensure that connections only come from certain points in the network.

Threat​

Anonymous attacker from adjacent network.

Expected Remediation Time​

⌚ 60 minutes.
