Ever tried to analyze IIS logs manually across dozens of web servers during a security incident? If so, you know the challenge: massive log files across multiple systems, cryptic log entries, and no easy way to correlate events. When running Microsoft Internet Information Services (IIS) across large infrastructures, log data accumulates quickly, increasing the risk of missing critical events. IIS log analysis software is designed to collect, parse, and analyze IIS web server logs to monitor activity, troubleshoot performance issues, detect threats, and demonstrate compliance.

Most Windows detection programs are anchored on a small set of well-known event IDs: 4624, 4625, maybe 4688 if process creation auditing is turned on. The events that actually describe an intrusion (the new service, the scheduled task, the explicit credential, the share enumeration) live elsewhere on the same host, often on channels that are not enabled by default. We have written before about why a 4625-only mindset leaves most of the attack chain in the dark; this post is the catalog that picks up where that argument ended.

The choice here is not between two interchangeable log tools. It is a choice about where you want parsing, routing, and failure handling to live. Filebeat runs close to the source and keeps collection small. Logstash sits in the middle of the flow and takes on filtering, enrichment, and fan-out. That architectural difference matters more than a feature checklist. Pick the narrower tool when your logs have one destination and your parsing rules are modest.

The default advice for any system running an unsupported operating system is simple: replace it. Upgrade to a supported platform. Move to modern hardware. Problem solved. It’s good advice in theory. As with many other things in life however, in practice it ignores everything that makes legacy infrastructure hard to deal with in the first place. For organizations running Windows XP, Server 2003, or other legacy 32-bit Windows systems, "just upgrade" is often the most expensive, disruptive, and operationally risky option on the table.

We are happy to announce the latest release of NXLog Platform, version 1.12. This release introduces full version history for agent configurations, giving you a clear audit trail and the ability to instantly restore any previous version. It also brings a redesigned Customer Portal with a streamlined onboarding experience and improved navigation. Want a quick overview? Watch a short demo showcasing configuration version history, one of the key new features in this release:

Compliance frameworks don’t have a checkbox for "we know it’s a problem, but we can’t afford to fix it right now." Yet that’s the position thousands of organizations find themselves in — bound by regulation to meet security standards that their operating systems are physically incapable of supporting. If you run Windows XP, Server 2003, or any other unsupported OS in a regulated environment, the compliance obligation doesn’t go away just because the upgrade path is blocked.
