Chapter 19: Auditing and Reporting Overview of the audit process Overview of the audit process 532 Figure 220: The audit flow Monitoring, auditing, reporting, and attack and system event responses are closely related pieces of the audit process. They function together to provide information to you about the activity on your Sidewinder G2. On the Sidewinder G2, you can monitor the status of various processes in real time, view stored audit information, generate detailed reports, and have Sidewinder G2 respond to audit events by alerting administrators and ignoring hosts sending malicious packets. The diagram below demonstrates how these pieces are related in the audit flow. Monitoring Using the Admin Console, you can monitor Sidewinder G2 activity and status in real time using the dashboard. Auditing auditd reads /dev/audit and places the information into audit.raw. This is the recorded audit stream. This is now "history" and contains everything that might be worth viewing. Reporting programs kernel live audit stream aka /dev/audit..... auditd /var/log/audit.raw auditdbd auditdb auditbotd auditbotd has a threshold and can trigger a response (see Chapter 20). Using the Admin Console, you can filter and view audit information. This is an SQL database of information maintained by auditdbd. It contains all relevant audit information. Using Sidewinder G2 Security Reporter, the Admin Console, or a third-party tool, you can generate detailed, easy-to-read reports.
Auditing on the Sidewinder G2 Chapter 19: Auditing and Reporting Auditing on the Sidewinder G2 Auditing is one of the most important features on the Sidewinder G2. The Sidewinder G2 generates audit each time the Sidewinder G2 or any Sidewinder G2 service is stopped or started. Audit is also generated when any of the Sidewinder G2’s audit facilities are modified. Other relevant audit information that is captured includes identification and authentication attempts (successful and failed), network communication (including the presumed addresses of the source and destination subject), administrative connections (using srole), and modifications to your security policy or system configuration (including all administrator activity, such as changing the system time). Audit can be viewed and monitored using tools such as Sidewinder G2’s dashboard, audit viewing and reporting windows, and the off-box Sidewinder G2 Security Reporter. Sidewinder G2 can also be configured to send alerts for particular types of audit using IPS Attack Responses and System Event Responses. The Sidewinder G2’s audit facilities monitor the state of log files to minimize the risk of lost data. Log files are compressed, labeled, and stored on a daily basis, and a new “current” log file is created. Using this mechanism, no audit data is lost during the storage transition. The amount of available audit storage space is monitored very closely on the Sidewinder G2 via the rollaudit and logcheck utilities to monitor the log file size and rotate log files as needed. (For information on using rollaudit, see “Rollaudit cron jobs” on page 599. For information on using the logcheck utility, refer to the logcheck man page.) There are three main components to the Sidewinder G2 audit process: • auditd — This is the audit logging daemon. This daemon listens to the Sidewinder G2 audit device and writes the information to log files. The log files provide a complete record of audit events that can be viewed by an administrator. auditd sends all audit data to a binary file called /var/log/audit.raw. • auditbotd — The Sidewinder G2 uses a daemon called auditbotd to listen to the audit device and gather the security-relevant information it finds. The auditbot daemon tracks these events and uses its configuration to determine when the data might be indicating a problem and require a response, such as an attempted break-in. If it does detect an audit event that has a configured response, Sidewinder G2 responds accordingly. For more information on configuring IPS attack and system event responses, refer to Chapter 20. • auditdbd — This daemon maintains the audit database. auditdbd monitors the audit stream and sends reporting information to the MySQL database called auditdb. The auditdbd server is disabled by default. Important: Reporting services are not available until the auditdbd server is enabled. For information on enabling the auditdbd server, see “Enabling and disabling servers” on page 65. 533
