We reviewed Department of Homeland Security’s (DHS) information security program in accordance with the Federal Information Security Management Act of 2002 (FISMA). Our objective was to determine whether DHS’ information security program is adequate, effective, and in compliance with FISMA requirements. DHS has taken steps to improve its information security program. For example, DHS expanded the ongoing authorization program to improve the security of its information systems through a revised risk management approach. Additionally, DHS developed and implemented the Fiscal Year 2014 Information Security Performance Plan, which defines the performance requirements, priorities, and overall goals for the Department. DHS has also taken actions to address the President’s cybersecurity priorities, which include the implementation of trusted internet connections, continuous monitoring of the Department’s information systems, and strong authentication. While these efforts have resulted in some improvements, Components are not consistently following DHS’ policies and procedures to update the system inventory and plan of action and milestones in the Department’s enterprise management systems. Further, Components continue to operate systems without the proper authority.
