Securing Production Troubleshooting with yCrash Audit Logs

How yCrash’s audit trail gives enterprise teams the visibility they didn’t know they were missing.

A few months ago, one of our enterprise customers asked us a question that really surprised me. They were reviewing their internal security and their Information Security team found something. They said: “We know who logs into production. We know who deploys code. Who is using yCrash? What are they doing in there? Shouldn’t these information be kept under lock and key?”

Valid question, right? And I did not have an answer at that time. Which really bothered me.

yCrash is an on-premise enterprise application – our customers download the build and deploy it entirely within their own environment. We do not host it or don’t have visibility about how it is being used. It was planned and designed this way because many of our customers operate in environments where keeping everything within their own system is not only crucial but also essential. As a result, they are responsible for knowing who is using yCrash and what actions are being performed within the platform.

But despite all this, most of our customers had no way to answer that question, about yCrash. And that exposed a question many organizations overlook: is production troubleshooting security being treated with the same importance as production security itself?

Why Production Troubleshooting Security Matters

Let’s take a step back and see why production troubleshooting security matters. yCrash is a platform that helps engineers troubleshoot problems with the JVM and system. Engineers use it to analyze GC logs, heap dumps, thread dumps, and system metrics, the kind of deep diagnostic data you turn to when something goes wrong in production. And that data can be very sensitive. It can include things like class names, memory information and configuration details. Sometimes it even has application data that ended up in the heap. Understanding what can exist inside heap dumps is important when thinking about troubleshooting security.  

So when engineers access sensitive production data through tools that aren’t being monitored, that becomes a real security gap. That’s the problem. 

Why JVM Diagnostic Data Is Sensitive

JVM diagnostic artifacts can contain far more sensitive information than most engineers realize. Heap dumps may include in-memory objects, configuration details, and sometimes application data that happened to be present at the time the dump was taken. Thread dumps and GC logs can reveal execution paths, system behavior, and infrastructure details. Because these artifacts provide deep visibility into how an application runs, they also introduce an important consideration for production troubleshooting security.

The Hidden Risk in Production Troubleshooting Security

Most companies invest a lot of money in securing their production systems: firewalls, VPNs and multi-factor authentication (MFAs), the works. But the thing is, the internal tools used to fix problems in production, often fly under the radar. That is not negligence, but people don’t think of a log analysis tool as something that needs to be secured. But in reality, it actually is. 

Let’s quickly see what happens if we don’t keep track of who is accessing what:

• Someone downloads a heap dump report and shares it externally. Nobody knows.
• An engineer who left the company three months ago still has access and is poking around. You don’t know.
• A support ticket gets escalated and someone asks “who accessed this report and when?”. You have nothing to give them.
• Your compliance team asks for evidence of access controls during an audit. You’re scrambling.

Believe me, none of these are hypotheticals. This happens more than we care to admit and I’ve heard stories from customers as well.

How yCrash Improves Production Troubleshooting Security

We implemented an audit trail feature in yCrash that writes a dedicated log file: usage-stats.log and usage-stats-json.log, capturing every meaningful user action inside the application. Page visits, file uploads, analysis runs, report views. Everything gets timestamped and recorded.

The really useful part kicks in when the customer has SSO configured. yCrash supports SSO authentication, and once that’s in place, every log entry is tied to the authenticated username. So instead of just knowing that someone viewed a GC report, you know who viewed it, which report, and exactly when.

Here’s what the log looks like in practice:

2025-12-30 20:15:02,278 - john.smith - visited URL http://appserver:8090/gc-index.jsp
2025-12-30 20:15:19,752 - john.smith - GC log: gc.log file upload started.
2025-12-30 20:15:21,395 - john.smith - GC log: gc.log file upload completed.
2025-12-30 20:15:24,828 - john.smith - gc.log analyzed successfully.
2025-12-30 20:15:33,269 - john.smith – viewed gc.log GC report

That’s a complete trace of one engineer’s session. They navigated to the GC analysis page, uploaded a log file, waited for it to process, and then viewed the report. Five lines. The whole story.

Without SSO, the username field is empty. The activity is still logged, but you lose the “who”. So enabling SSO authentication is really what makes this feature go from “somewhat useful” to genuinely valuable from a security standpoint.

How to Enable Audit Logging in yCrash

Since yCrash is deployed entirely within the customer’s own environment, setup is straightforward. The usage-stats.log file is written automatically by the yCrash application. There’s nothing to turn on for the basic logging to work. It starts from day one.

For username tracking, the customer needs to configure SSO integration in yCrash. This involves configuring your IdP and SP(yCrash) URLs in saml.xml file. Once that’s done and engineers are authenticating through SSO, the usernames start appearing in the logs automatically.

Because yCrash runs inside the customer’s infrastructure, the log file lives on their own servers. They can feed it into whatever log management or SIEM tooling they already use: Splunk, ELK stack, Datadog, whatever.

How Audit Logs Improve Production Troubleshooting Security

I would like to go back to that customer conversation I mentioned in the start of the blog. After we made the changes and they delpoyed the new version, their Information Security team reviewed it again. This time, they could pull the usage logs, filter by username, and see exactly who had accessed the application over the past quarter, what they had uploaded, and what reports they had viewed.

A simple feature was able to bridge the gap that was causing problems to our enterprise customers. Especially for companies in regulated industries where access logging is not optional. 

It also changed something more subtle. When engineers know their actions are being recorded, they’re more deliberate. They don’t casually poke around in reports that aren’t relevant to their work.

Production Security vs Production Troubleshooting Security

Your production environment is probably well-secured. Years of effort, multiple layers, regular audits. But the tools your engineers use to troubleshoot that production environment, are they held to the same standard?

For yCrash customers, the answer is now yes. The audit trail isn’t a flashy feature. You won’t see it front and center in a product demo. But the customers who have gone through a security review or compliance audit with it in place will tell you it’s one of the more quietly important things we’ve shipped.

If you’re running yCrash in your environment and haven’t configured SSO yet, this is a good reason to. The logging is already happening. You’re just one configuration step away from knowing exactly who is doing what.
