You are a network security technician at a mid-sized company. Your employer is planning for significant growth and the CIO has tasked you with implementing a system to consolidate all critical network device logs to a central location. The system should support logs from all routers, firewalls, switches and business critical servers and should send alerts in the event of security issues. What type of solution would best meet these requirements?
Security Information and Event Management (SIEM) systems are used to centralize logging and alerting from various types of network devices. Common functionalities include data aggregation, alerting, forensic analysis and data retention/compliance. They are most commonly found in mid-size to larger networks where there are too many devices to monitor separately.
