Dynamic security routines should be run on a periodic basis to ensure that these critical files have not be modified without proper approval. One contains the formatted audit report, the filename being in the format: Account Security Inform users of "good" password selection criteriaand use either a pro-active password checker or a password cracking program to verify that passwords are secure e.
For example debugging something on the system, or watching processes or users for only a day or two would give immediate output in stream mode.
Then, using sed to pull the paired records together on the same line, we would also need to produce a header for the report. Audit configuration files When you start configuring auditing, it is pretty much a case of trial and error when you initially start collecting audit events, which, no doubt, system administrators whom have audit running will verify.
For example assume the user genrep1, which is a generic user-id, and you do not require these events in your report, you could use: You can specify the following values: Obtain a listing of all user accounts and verify that each user is still an active worker on the system.
In the objects file, you specify which filename called an object should be monitored for either a read, write, or execute operation.
Audit overview AIX audit can be configured to operate in three modes: This file contains the following: If you specify false here the userid is locked for all locally attached terminals but might not be locked for remote access.
When collecting audit reports within an enterprise environment, I suggest it is best done by collating all the reports into one email for review. You should periodically "audit" your network, or install tools that will automatically monitor some aspects of system security and notify you of anything that is discovered.
User bravo has also attempted to su to root, but has failed. Stream auditing output hints 1. Audit report The auditroll script could be executed every weekday to gather a report on the previous days audit activities. AIX provides the auditselect utility to select event records from the audit log.
In the objects file, you specify which filename called an object should be monitored for either a read, write, or execute operation. Your configuration may well be different. This can be obtained by using the following command and file: AIX servers evaluate compliance checks.
Determine that the proper person or group is responsible for monitoring the network that support the file server. Because we have informed audit to print the trail part of the record, we can now see that the command options parsed to pwdadm was the 'alpha -c'.The DIY AIX System Health Checklist is for system administrators to give some pointers on things to look at and monitor on their systems; It has been developed in my many years in AIX Support with much assistance from colleagues and reading (documentation.
AIX audit can be configured to operate in three modes: stream, bin, or stream and bin. The stream mode is my personal choice, because it offers real-time viewing of audit events due to the audit log file being written to in text mode.
Using the AIX audit produces a lot of records that are triggered by the configured events on the system. These events need to be kept for an external audit reviewer. However, for day-to-day internal reports, a lot of these events can be filtered out, and the remaining records can be used to produce a more centered, daily audit report.
AIX provides the auditselect utility to extract records. Computer security training, certification and free resources. We specialize in computer/network security, digital forensics, application security and IT audit. AIX CHECKLIST By: Frank W.
