The purpose of the article is the characteristics of state administration and the function it performs in the state security system. State administration plays a key role in ensuring the security of citizens by creating, implementing and monitoring policies and activities aimed at protecting the interests of the state. The article focuses on three main areas of administration's operation in the state security system. First of them is crisis management, which requires effective administration in emergency situations. Internal security is another area, which includes crime prevention, the fight against corruption and maintaining public order. The third area is external security, which concerns the defense of the country against external threats, such as armed conflicts or terrorism. The state administration cooperates with the armed forces, intelligence and other security agencies to ensure effective protection of borders and state interests. The article also emphasizes the role of cyber security administration.
