All of the items mentioned in the Design Considerations list above are factors in the size of the SOC. Strategic SOC design accounts for current SOC functions while anticipating space needs for future (or envisioned) consolidated or collaborative services that SOC personnel may perform. Many technology factors have greatly reduced the floor, working and console space needed for SOC functions including server virtualization, digital video, data and management aggregation services, and VOIP networked communication systems. Conversely, large display screens and walls that may not have existed previously are an increasingly popular way to enhance communications between operations center personnel.
Current and Future Technology
The increasing pace of technology development and the increasing value of new security technology mean that SOC design must consider both current and future technology. IT standards-based technologies provide future-proofing in three senses: First, the computing and communications infrastructure will continue to be compatible with future technology development; second, the communications infrastructure is independently scalable and upgradeable; and third, interoperability between components and systems continues to grow, which increases the value of the existing technology investment.
Common standards-based infrastructures among systems means that security systems design can focus more on security applications and less on technology details. This is coincidentally a focus also on the security ROI elements—where a security manager's attention should be focused. The nature of SOC upgrades has changed from complete “forklift” redesigns, to designs that can evolve as both technology and security applications needs evolve. The approach of previous decades, to redesign a SOCs every 5 to 10 years, is being replaced by ongoing SOC technology lifecycle planning . Security executives and managers can learn a lot from their IT departments about how this beneficially impacts budget planning and management approvals. The lifespan of a current-technology SOC will be determined by an organization's strategic and tactical security planning (such as consolidation or regionalization) according to business needs, rather than by technology changes.
James Connor, CEO of security consulting firm N2N Secure and former senior manager of Global Security Systems for Symantec Corp., points out that human capital development for SOC functions is highly important, but is often overlooked. “The SOC team is a critical part of the security operations ecosystem,” Connor says. “The correct perspective starts with the team and goes from there. The technology simply provides the tools that the SOC needs to get the job done. That's why the design effort should include metrics to measure how the job is getting done, and to provide insight into the upgraded operations.
“When redesigning a SOC, the security manager must re-evaluate the SOC's mission statement,” Connor continues. “What is the mandate? What security policies and procedures are appropriate for the business today? That last thing that you want is to have an SOC upgrade amount to nothing more than ‘putting a new paint job' on an existing SOC.”
