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.
