INTRODUCTION
Security Information and Event Management (SIEM) solutions were introduced to provide enterprises with network security intelligence and real-time monitoring for network devices, systems and applications.
With SIEM solutions, IT administrators can mitigate sophisticated cyber-attacks, identify the root cause of security incidents, monitor user activity, thwart data breaches and most importantly meet regulatory compliance requirements.
Network infrastructures of any enterprise include network devices (routers, switches, firewalls, etc.), systems (Windows, Linux, etc.) and business critical applications that generate a huge amount of log data.
These log data contains vital information that can provide powerful insights and network security intelligence into user behaviors, network anomalies, system downtime, policy violations, internal threats, etc.
Meeting your IT security requirements by manually analyzing the log data is impossible because the log data that is generated is enormous and not enough actionable information can be derived from it if done manually.
Real-time log monitoring and analysis cannot be achieved if done manually.
Automation is the key and that’s where Security Information and Event Management (SIEM) solutions come in to automate the entire process of log management thereby providing real-time network security.
Log Analysis
The task of analyzing precise information in real-time from terabytes of log data holds as the greatest challenge for network administrators.
Analyzing and correlating log data manually for IT security is impossible and is always prone to human error.
Administrators need to rely on automated solutions that can help them in analyzing the huge amounts of log data generated by their network infrastructure.
Administrators need to be notified in real-time during anomalies in applications, systems, and devices.
Analyzing log data using automated tools can also help administrators to identify suspicious user activities on the network.
