Portable Soc Log Analyzer For Isolated Networks (offline Siem Lite)

Abstract

The Growing Complexity Of Cyber Threats Has Increased The Importance Of Continuous Monitoring And Analysis Of System Logs. Analyzing System Logs Reveals Patterns Of Activity That Help Uncover Unusual Behaviour And Possible Security Issues. However, Most Modern Security Information And Event Management (SIEM) Solutions Rely On Cloud Infrastructure And Require Constant Internet Connectivity, Which Limits Their Usability In Isolated Or Restricted Environments. This Paper Introduces A Portable SOC Log Analyzer, A Lightweight And Offline-capable System Designed To Perform Log Analysis Without External Dependencies. The System Collects Logs From Multiple Sources, Processes Them Into Structured Formats, And Applies Rule-based Detection Techniques To Identify Suspicious Activities Such As Repeated Login Failures, Unauthorized Access Attempts, And Abnormal Behaviour Patterns. The Proposed Solution Includes Features Such As Alert Generation, Log Filtering, And Graphical Visualization Through A User-friendly Interface. Because It Operates Fully Offline, The Tool Preserves Privacy And Remains Dependable, Which Makes It Well-suited For Isolated Or Air‑gapped Systems.
