Auditing the security infrastructure
You can use the Auditing Facility to report and track auditable events to ensure the integrity of your system.
Before you begin
About this task
- Confirming the effectiveness and integrity of the existing security configuration.
- Identifying areas where improvement to the security configuration might be needed.
- Principal/Credential Mapping
- Audit policy management
These types of events can be recorded into audit log files. Each audit log has the option to be signed and encrypted to ensure data integrity. These audit log files can be analyzed to discover breaches over the existing security mechanisms and to discover potential weaknesses in the current security infrastructure. Security event audit records are also useful for providing evidence of accountability and nonrepudiation as well as vulnerability analysis. The security auditing configuration provides four default filters, a default audit service provider, and a default event factory. The default implementation write to a binary text-file based log. Use this topic to customize your security auditing subsystem.
Enable the security auditing
Security auditing will not be performed unless the audit security subsystem has been enabled. Global security must be enabled for the security audit subsystem to function, as no security auditing occurs if global security is not also enabled.
Assign the auditor role to a user
A user with the auditor role is required to enable and configure the security auditing subsystem. It is important to require strict access control for security policy management. The auditor role has been created providing granularity to allow for separation of the auditing role from the authority of the administrator. When Security Auditing is initially enabled, the cell administrator has auditor privileges. If the environment requires separation of privileges, then changes will need to be made to the default role assignments.
Create security auditing event
You can configure event type filters to only record a specific subset of auditable event types in your audit logs. Filtering the event types that are recorded makes for easier analysis of your audit records by ensuring only those records important to your environment are archived.
Configure the audit service provider.
The audit service provider is used to format the audit data object that was passed to it before outputting the data to a repository. A default audit service provider implementation is in included. See Configuring the default audit service providers for security auditing for more details on the default implementation. A third party implementation can also be coded and used. See Configuring a third party audit service providers for security auditing for more details on this implementation.
Configure audit event factories for security
The audit event factory gathers the data associated with the auditable events and creates an audit data object. The audit data object is then sent to the audit service provider to be formatted and recorded to the repository.
Protect your security audit
It is important to secure and ensure the data integrity of the recorded audit data. To ensure that access to the data is restricted and tamper proof, you can encrypt and sign your audit data.
Configure security audit subsystem failure
Notifications can be enabled to generate alerts when the security auditing subsystem experiences a failure. Notifications can be configured to record an alert in the System logs or can be configured to send an alert through email to a specified list of recipients.
