The Department of Defense developed both IAM and IAT in 2004. These are technical and managerial qualification criteria designed to ensure that the Department of Defense’s IT systems are staffed with employees who meet a particular level of technical expertise. Information Assurance Technical (IAT) is an acronym for Information Assurance Technical. Passing various exams and having specified work experiences that meet specific requirements are required for each level of IAT certification. These standards are intended toward technical workers and are focused on technical knowledge. Information Assurance Management (IAM) is an acronym for Information Assurance Management. Passing various exams and having specified work experiences that meet specific requirements are required for each level of IAM certification. These standards are directed for management and leadership personnel. There are three tiers of IAT and IAM standards: 1, 2, and 3. Level 1 certifications are considered entry-level, level 2 certifications are intermediate, and level 3 certifications are expert. To be considered for government positions and many commercial business jobs, applicants must meet one of the certification levels as a minimum requirement.
