About the Cyber Information Assurance Analyst III role
A Cyber Information Assurance Analyst III is a senior-level cybersecurity professional responsible for ensuring the confidentiality, integrity, and availability of critical information systems. These experts operate at the intersection of technical security and regulatory compliance, serving as the primary assessors who validate that networks and systems adhere to strict security policies and government standards. Unlike entry-level roles, a Level III analyst works with significant autonomy, applying extensive technical expertise to guide major programs and often functioning in a project leadership capacity.
The core of this profession revolves around the Risk Management Framework (RMF). Analysts conduct comprehensive security assessments, performing detailed risk analysis and control validation across all steps of the authorization process. They evaluate system architectures, verify authorization boundaries, and categorize data based on sensitivity levels. A significant portion of the work involves identifying vulnerabilities and ensuring systems comply with Security Technical Implementation Guides (STIGs) and Security Requirement Guides (SRGs). When deviations are found, the analyst tracks them through Plans of Action and Milestones (POA&Ms), assessing residual risk and reporting findings to authorizing officials.
Daily responsibilities typically include coordinating with information system security managers and program management offices to understand evolving system architectures and security requirements. These professionals lead on-site assessment visits, conduct technical briefings, and maintain meticulous documentation in governance databases. They evaluate change requests, firewall exceptions, port/protocol configurations, and web filtering rules. The role requires constant vigilance, tracking system changes and their security impacts throughout the entire system lifecycle. Analysts also generate weekly activity reports and stay current with evolving regulations and threat landscapes through continuous training.
To succeed in these jobs, candidates typically need a deep, demonstrable understanding of key frameworks including NIST Special Publications 800-37 and 800-53, as well as CNSSI 1253. Technical proficiency is essential across diverse domains such as network security, Windows and UNIX operating systems, cloud environments, and endpoint security solutions. Familiarity with vulnerability scanning tools like Nessus, ACAS, and SCAP, along with governance platforms like eMASS, is standard. Most positions require an active Top Secret clearance with SCI eligibility and compliance with DoD 8570 standards, typically holding an IAT Level II certification. A bachelor’s degree combined with eight or more years of systems security experience is common, though equivalent combinations of education and experience are often accepted. Strong customer service skills are also vital, as these analysts must communicate complex technical risks to non-technical stakeholders effectively. Ultimately, these jobs demand a unique blend of technical depth, regulatory knowledge, and leadership capability to protect national security systems.
