Re: SOC and SIEM

[Kartik.netsec () gmail com]

A Security Operations Center (SOC) is a department within a company or often outsourced which does (but not limited to) 
configuration management, change management of security devices like Firewalls, IDS/IPS, VPN, SIEM, AV etc. They also 
perform Security Incident response and Monitor the near real-time logs with the help of SIEM tools. There may be 
dedicated teams within a SOC with different reporting hierarchy for Device management and Monitoring to avoid conflict 
of interest depending upon contract/ legal requirement etc.

A Security Information & Event Management (SIEM) tool is simply a correlation tool through which SOC monitors the near 
real-time logs. It logs (if working properly :D) qualified events and alerts whenever there is an incident. It may also 
create tickets in local ticketing tool and send email/ sms alerts when integrated with other tools. You can tweak the 
tool as per your requirement.

Thanks,
Kartik, CISSP
