Securing Your Castle: Building a Budget-Friendly Security Operations Center (SOC)
In today’s digital age, cybersecurity threats are increasingly sophisticated and prevalent, making it essential for organizations of all sizes to have robust security measures in place. A Security Operations Center (SOC) plays a crucial role in defending against these threats by providing continuous monitoring, detection, and response to security incidents. However, setting up a SOC can be expensive, particularly for small to medium-sized businesses. This article outlines practical steps to build an effective SOC on a budget without compromising on security.
i. Understanding the SOC
A Security Operations Center (SOC) is a centralized unit that deals with security issues at both technical and organizational levels. It involves people, processes, and technology to monitor and improve an organization’s security posture while preventing, detecting, analyzing, and responding to cybersecurity incidents.
