Analyze IIS logs and monitor critical IIS server events in real-time with EventLog Analyzer

Microsoft IIS servers, both web and FTP, have become essential for businesses. However, an IT security administrator's job doesn't stop with deploying IIS servers. Post deployment, administrators have to adopt security measures to protect those servers. One proven way to monitor the security of IIS servers is by installing a log management tool that provides out-of-the-box support for IIS logs.

EventLog Analyzer is a comprehensive tool that can manage and audit your Microsoft IIS server logs and provide you with crucial insights on the activities happening in your IIS servers. This software has out-of-the-box support for both IIS web and IIS FTP server logs, and provides in-depth reports that make your auditing job a lot easier.

Learn how EventLog Analyzer serves as an effective IIS log analyzer tool with its advanced analytical capabilities and end-to-end log management features.

IIS log collection and processing  

The log collection process in EventLog Analyzer has been designed to be automated, efficient and seamless with options for both agent-based and agentless-log collection. Also, you can manually configure the log collection settings for IIS servers, select specific sites for monitoring, and add filters to collect necessary data. The collected logs are transferred to the EventLog Analyzer server in real-time and are processed at a rate that can go up to 25,000 logs per second.

IIS log parser  

EventLog Analyzer supports parsing logs generated in any format. This includes W3C Extended log file format, NCSA Common log file format, and ODBC logging. This log management tool is also equipped to handle heterogeneous environments hosting multiple of versions of IIS servers (IIS 6.0, IIS 7.0, IIS 8.0, IIS 10, etc.).

By default, the log parsing is done by extracting standard fields like client and server IP address, timestamp of events, server name, and port number. You can also use the custom log parser to index new fields and generate custom patterns to parse logs.

IIS web server log analysis  

EventLog Analyzer monitors, analyzes, and audits IIS web server events and provides reports on error events, security attacks, usage analytics, and many more facets of your IIS servers.

• Error reports: These reports list the errors that users experienced while trying to access the websites hosted on your IIS web servers, such as failed user authentication, HTTP bad request, HTTP request entity too large, and gateway timeout. They also help you identify the problems users frequently face, so that you can come up with corrective steps to ensure a hassle-free experience for users.
• Security reports: Server attack reports give information on the attacks detected by EventLog Analyzer in your IIS web servers, such as SQL injection and DDoS. EventLog Analyzer comes with prebuilt alert profiles that can notify you in real time when such attacks are detected. You also get exclusive reports providing information on the users who most frequently access your server, along with server activity trends.

IIS FTP sever log analysis  

EventLog Analyzer's reports on IIS FTP servers help in monitoring, tracking, and optimizing user activity by providing you with countless reports on important logons, file downloads, security data exchange, and base sequences of commands. The intuitive dashboard of this IIS log analysis software allows administrators to effortlessly access raw log data and spot the origin point of any activity.

IIS log visualization and reporting  

EventLog Analyzer helps you observe log trends by instantly visualizing the log data and presenting the results in graphic reports. Toggle between between multiple graph forms, add the reports as widgets on your dashboard, and compare different trends to get a comprehensive view of your IIS server events. You can also export the reports, schedule them to be mailed to your inbox periodically, and add them as incidents.

Other solutions offered by EventLog Analyzer

Log archival

Utilize the automated log archiving feature in EventLog Analyzer to securely store IIS logs, comply with security mandates such as Cybersecurity Maturity Model Certification(CMMC), Codes of Connection(CoCo), Good Practice Guide(GPG), and FERPA that require IIS log data, and conduct forensic analysis in case of web server attacks and network compromise.

Real-time alerting

Set-up alerts for critical anomalies and error events using EventLog Analyzer's alerts dashboard which contains predefined alert criteria based on IIS report profiles. Enable real-time notifications via email or SMS, add alert severity level, customize the alert message format, set the threshold values for the alert trigger, and configure other advanced settings to create a complete profile.

Windows log analyzer

Audit Windows environments thoroughly with EventLog Analyzer's reports for Windows client machines, servers, firewalls, user activities, active directory, and Windows based threats.

Application log monitoring

Along with monitoring IIS web and FTP servers, EventLog Analyzer also supports Apache servers, database applications such as MySQL, Oracle server, IBM Db2 and PostgreSQL, DHCP servers, print servers, and third party applications.

Event correlation

Correlate IIS logs with events detected across various endpoint devices and applications to identify threat patterns and attack attempts. One example is an application suddenly crashes and new files pop up on your server. This can be correlated with spikes in the interaction with a new external IP by analyzing the firewall logs. This is a possible indicator of a threat actor transferring malware payload to your IIS server. Similarly, EventLog Analyzer offers over 30 predefined correlation rules, options to customize and create new rules, and trigger alerts when patterns are matched.
