Security is a risk analysis and management activity, therefore, keeping up with FISMA regulations is vital to ensuring system confidentiality, integrity, and availability. This starts with a successful system authorization to operate and proper alignment to the risk management framework (RMF). Castalia utilizes prior system IA experience; existing documentation templates; and support resources and artifacts gained from previous contracts to assist customers with updating cyber security policies, tracking tools, user and operator training and process guides. To ensure compliance with all applicable laws, directives, policies, and directed actions, we employ guidance and direction from the NIST SP 800-37 RMF, NIST 800.53, NIST 800.171, ICD 503, to implement a unified approach to defending the customer systems across multiple network domains.
