The Management Authority should adopt its own security plan in relation to Central SIS II once it will have taken up its responsibilities. This security plan should therefore expire, to the extent it relates to the Central SIS II, when the Management Authority takes up its responsibilities.

The security plan should foresee one System Security Officer performing security-related tasks concerning both Central SIS II and the Communication Infrastructure and two Local Security Officers performing security- related tasks concerning the Central SIS II and the Communication Infrastructure, respectively. The roles of the security officers should be laid down in order to ensure efficient and prompt response to security incidents and reporting thereof. A Security Policy should be set up describing all technical and organisational details in line with the provisions of this Decision. Measures should be defined to ensure the appropriate level of security of the operation of Central SIS II and the Communication Infrastructure,
