This policy checks whether access logging is enabled on Web Cache. To effectively manage Web Cache, it is necessary to get feedback about the activity and performance of the server, as well as any problems that may be occurring.
The server access log records all requests processed by the server. The ACCESSLOG element in $ORACLE_HOME/webcache/webcache.xml
is used to configure this.
Policy Summary
The following table lists the policy's main properties.
Severity | Category | Target Type | Versions Affected | Policy Rule EvaluationFoot 1 | Automatically Enabled? | Alert Message |
---|---|---|---|---|---|---|
Critical | Security | Web Cache | Oracle Application Server 9.0.4.x and Oracle Application Server 10.1.2.x | The underlying metric has a collection frequency of once every 24 hours. | Yes | Access logging is not enabled for Web Cache. |
Defaults
Parameters and Their Default Values
None
Objects Excluded by Default
None
Impact of Violation
Absence of an access log can severely cripple administrators' ability to monitor malicious attacks.
Action
Enable access logging for Web Cache.
This policy checks whether a Dummy Wallet is being used on Web Cache.
A dummy wallet is located in $ORACLE_HOME/webcache/wallets/default
on UNIX and ORACLE_HOME\webcache\wallets\default
on Windows. This wallet is intended for testing purposes for OracleAS Web Cache HTTPS communication to origin servers.
For a production environment, use the procedures described in the documentation to create a new wallet with Oracle Wallet Manager. By default, Oracle Wallet Manager stores wallets in directory /etc/ORACLE/WALLETS/user_name
on UNIX and %USERPROFILES%\ORACLE\WALLETS
on Windows.

This policy verifies that the webcached binary is not owned by a super user.
Binaries with suid privilege can be exploited to get extra privileges on the host. If a super user owns the webcached binary and the suid bit is set, a malicious user can exploit it to gain super user privileges on the host.
Policy Summary
The following table lists the policy's main properties.
