An effective cybersecurity posture is achieved when there is confidence that information and information systems are protected against attacks. This is done through the application of security services in such areas as availability, integrity, authentication, confidentiality, and non-repudiation. Since technical mitigation has no value without trained people to use them and operational procedures to guide their application, it is paramount that in implementing an effective and enduring cybersecurity framework, organizations achieve a synergistic balance from all three facets of a Defense in Depth strategy: people, operations, and technology. Within the Department of Defense (DOD), Cybersecurity Service Providers (CSSPs) play a unique component of the Department of Defense’s defense in-depth strategy.
