Analyzing Logs For Security Information Event Management

Importance of Log Analysis

Download PDF

All network systems and devices like Windows/Linux desktops & servers, routers, switches, firewalls, proxy server, VPN, IDS and other network resources generate logs by the second. And these logs contain information of all the system, device, and user activities that took place within these network infrastructures. Log files are important forensic tools for investigating an organizations security posture. Analysis of these log files provide plethora of information on user level activities like logon success or failure, objects access , website visits; system & device level activities like file read, write or delete, host session status, account management, network bandwidth consumed, protocol & traffic distribution; and network security activities like identifying virus or attack signatures and network anomalies.

What is Security Information Event Management?

Security Information Event Management (SIEM) refers to the concept of collecting, archiving, analyzing, correlating, and reporting on information obtained from all the heterogeneous network resources. SIEM technology is an intersection of two closely related technologies, namely the Security Information Management (SIM) and Security Event Management (SEM).

Security Information Event Management

According to Wikipedia "Security Information Management (SIM), is the industry-specific term in computer security referring to the collection of data (typically log files; e.g. eventlogs) into a central repository for trend analysis. This is a basic introductory mandate in any computer security system. The terminology can easily be mistaken as a reference to the whole aspect of protecting one's infrastructure from any computer security breach. Due to historic reasons of terminology evolution; SIM refers to just the part of information security which consists of discovery of 'bad behavior' by using data collection techniques..." So, to a large extent SIM is concerned with network systems, like Windows/Linux systems, and applications. As a technology SIM is used by system administrators for internal network threat management and regulatory compliance audits.

SEM on the other hand is concerned with the "real time" activities of network perimeter devices, like firewalls, proxy server, VPN, IDS etc. Security administrators use SEM technology for improving the incident response capabilities of the perimeter/edge devices through network behavioral analysis. The target audience for SEM technology is NOC Administrators, Managed Security Service Providers (MSSP), and of course the Enterprise Security Administrators (ESA).
