The majority of the committee's activity takes place in its subcommittees, while the committee as a whole largely serves as a media stage for top defense decisionmakers. The committee approves extensive subcommittee-drafted delegeted legislation in areas of defense, emergency preparedness, emergency recruitment of human resources, Shabak special operations, allocation of emergency equipment, the deployment of the Home Front, and other security and intelligence related tasks. The committee is presented with summaries by the top decisionmakers in areas of foreign affairs, defense, and intelligence, including by the Prime Minister, the Foreign Affairs Minister, the Minister of Defense, and the heads of Mossad, Shabak, and Aman. The committee's chair, who reports on much of the country's defense activities, is considered one of the most senior figures in the Security Forces and subsequently, it is one of the most sought after positions in the Knesset. The committee's plenary sessions are secret and the meetings of some of its subcommittees are top secret. Consequently, its protocols remain largely unpublished. After repeated instances in which the contents of meetings were leaked, its members became obliged to sign a secrecy affidavit. The media has limited access to committee meetings (at selected occasions) and no access to that of its subcommittees. The government is obligated to bring to the approval of the committee various emergency activities, including ones related to or that are likely to result in war. The committee also undertakes personal hearings for key defense and State decisionmakers as well as hearings for appreciable defense projects.
