In the 21st Century, America's greatest threat may be lapses in digital security. That's why the U.S. government and military are beefing up information security. Improved security means hiring workers who can keep our national data and technology safe. To make sure it employs skilled personnel, the government requires every employee with privileged access to a Defense Department IT system to get commercial IT certification. From entry-level computer basics to intensive penetration and hacking, this training gives prospective DoD workers comprehensive expertise in national information technology and the security issues that surround it. The U.S. Defense Department is the largest employer in the world. If you want to join the more than 3 million service members, civilians, contractors and foreign nationals on its payroll, you need to take some online coursework first. Directive 8570.1 requires that civilian and military personnel get internationally-recognized professional certifications. The training is for IT personnel working in national defense, but the skills can translate to a wide range of employment opportunities. For example, CompTIA courses that are part of the training are also part of the certification track for Microsoft, HP and Cisco and are mandatory for service technicians at Dell and Intel. The IT training certifications required to meet the requirements of the DoD directive include: CompTIA A+ This certification is useful in careers as a computer support professional or IT technician. In addition to having strong technical knowledge, these professionals have good customer service skills.
