To build an effective security operations center (SOC), you must first understand what type of SOC you need by considering its capabilities, organization, staffing hours, and environment. Key planning areas include defining hours of availability, whether to use an MSSP, priority capabilities, and the technology environment. Budget and technology are also important to consider, but only after establishing goals. An effective SOC requires the right mix of processes, people, and technologies tailored to your organization's unique needs.
