The Essential Guide to Auditing WebSphere DMGR Console Access

Hi friend!

Keeping close tabs on who is accessing the WebSphere Deployment Manager (DMGR) console and what changes they are making is incredibly important for securing your production environment. The DMGR is the central point of control for WebSphere – so protecting it should be a top priority.

In this comprehensive guide, I‘ll walk you through everything you need to know about auditing DMGR access and changes. You‘ll learn:

Why proper DMGR auditing is essential
Step-by-step how to enable logging
How to interpret and use the log files
Extra DMGR security hardening tips
How to monitor other critical points like app servers
Bonus advice for air-tight WebSphere security

Let‘s dig in!

Why DMGR Auditing Matters

Here are some key reasons why monitoring and logging all DMGR console activity is so critical:

Increased Visibility

DMGR logs provide clear visibility into who is accessing the console and what actions they are taking.
This level of visibility is invaluable in complex, large-scale WebSphere environments where many different admins may have access.

Improved Accountability

Logs give each admin accountability for their changes.
This encourages responsible behavior, especially if staffers know their actions are being recorded!

Simplified Auditing

Auditing WebSphere changes becomes easy with comprehensive DMGR logs versus piecing together data from different sources.
Logs serve as a detailed audit trail for internal compliance or external regulatory audits.

Enhanced Troubleshooting

If issues arise after changes were made, access logs make troubleshooting easy by pinpointing who made what change and when.
No more guessing games trying to unravel problems!

Quick Rollback Ability

Logging provides rollback capabilities to rapidly revert problematic changes.
This ability to "turn back time" is invaluable for production systems.

Improved Security

Logs help detect unauthorized access attempts or suspicious activity for further investigation.
This strengthens overall security posture.

Regulatory Compliance

Strict regulations like HIPAA and PCI mandate logging of all admin access for compliance.
DMGR logs help check the box on compliance requirements.

As you can see, comprehensive logging is invaluable for securely operating a production DMGR. Now let‘s look at how to set it up…

Step-by-Step Guide to Enabling DMGR Console Logging

Enabling detailed logging of all DMGR access and changes involves configuring WebSphere to use the NCSA Common Log Format. Here is what to do:

1. Start by Backing Up the DMGR Config

Since we‘ll be modifying the DMGR configuration, it‘s wise to first back up the existing config as a precaution.

Use WebSphere‘s backupConfig command to generate a full backup archive:

./backupConfig.sh -archive /backups/dmgr_config_backup.zip

Store this archive somewhere safe in case you ever need to restore the original settings.

2. Navigate to Logging and Tracing Settings

Log into the DMGR Console and go to:

System Administration > Deployment manager > Logging and tracing

Under there, select the NCSA access and HTTP error logging option.

3. Enable NCSA Logging Service

In the NCSA settings, check the box to Enable logging service at server start-up.

This activates the NCSA logging mechanisms.

4. Select Combined Log Format

For NCSA access log format, choose the Combined option from the dropdown menu.

Combined format includes the most useful fields for each access log entry.

5. Apply Changes and Bounce DMGR

Click Apply and OK to save the new settings. But they won‘t actually take effect…

Until you restart the DMGR for the changes to be applied!

Bounce the DMGR instance for NCSA logging to kick in.

6. Verify http_access.log Generation

After restart, verify that a new http_access.log file was created under dmgr/logs/.

This file will now contain detailed DMGR access activity! Time to break out the log analysis skills.

7. Interpreting and Analyzing the Logs

Here are some key fields to pay attention to when reviewing http_access.log:

Client IP – The source IP of the user who accessed DMGR.
Timestamp – Exact date and time of access.
Request – Specific DMGR API or resource that was interacted with.
Status Code – HTTP status code for the request.
User Agent – Browser or client type used.
Other – Extra info like session tokens.

For example:

172.16.179.135 - - [13/Aug/2015:04:25:16 -0700] "POST /ibm/console/j_security_check HTTP/1.1" 302 0 "https://172.16.179.135:9043/ibm/console/logon.jsp" "Mozilla/5.0 (X11; Linux x86_64; rv:24.0) Gecko/20100101 Firefox/24.0"

This shows an admin logging in from 172.16.179.135 on 8/13/15 at 04:25:16 via Firefox on Linux. Very helpful!

Now you have full visibility into all DMGR access activity for auditing.

Extra Tips for Robust DMGR Logging

Here are some bonus tips for configuring robust DMGR access logs:

Set Appropriate Rollover Settings

The default max log size is 500MB. To avoid a single huge file:

Increase the max size higher if needed
Enable rolling log files (ex: 10 x 100MB files)

Find the ideal balance for your environment.

Adjust the Log File Location

By default, http_access.log gets stored in dmgr/logs/. Change this if you want the logs in a different spot.

Mind the Performance Impact

Excessive logging levels can hurt performance. Strike a balance between logging and overhead.

Rotate Logs Regularly

Have a process to periodically archive and delete old log files to avoid filling up disk space.

Restrict Access to Log Directory

Tightly limit and monitor who has file access to the DMGR logs directory to prevent tampering.

Going Beyond Just the DMGR

While the DMGR console is critical, there are other important spots to enable enhanced logging:

App Server Access – Log app server admin console access, deployments, etc.
HTTP Access – The web containers and apps often house sensitive data.
DataSource Access – Log database connection pooling activity.
JVM Instrumentation – Low-level JVM logging provides insane detail.
Audit Logs – Cross-component logging of all security events.
FFDC Logs – Errors and exceptions via First Failure Data Capture.

Get all of these faceted logs humming for true production readiness!

Expert Recommendations

Here are my top expert recommendations for unlocking watertight WebSphere security:

Implement Centralized Logging

Forward and aggregate all the logs from across your WebSphere environment into a central SIEM or log analysis platform. This provides the full eagle-eye view you need for threat detection and compliance.

Enable Log Correlation

Correlate log data with your network flows, endpoint data, access control systems, etc. This connects the dots to see the full scope of activity.

Analyze Logs in Real-time

Real-time stream analysis of logs enables identifying issues as they occur vs. after the fact. This vastly improves response time.

Define Alert Rules

Configure intelligent rules to automatically alert on suspicious access attempts, anomalies, etc. Don‘t rely only on human review.

Back Up Logs Externally

Ensure logs get backed up to external durable storage so they can‘t be modified on the source systems. Maintain immutable evidence.

Utilize Log Review Automation

Leverage AI to automate aspects of log review for 24/7 coverage. Bring human expertise to the data via SOAR.

Conclusion

I hope this guide provided you with a very thorough understanding of locking down DMGR console access logging for security and compliance!

Enabling NCSA-format logging provides the transparency and auditability you need into administrative changes. Combined with all the other tips covered, you‘ll be well-positioned for production readiness.
