(5) The Agency shall submit to the Commission and ENISA a summary annual report on the notifications received and the measures taken in accordance with the first, second or third paragraphs of this Article no later than by the end of February for the preceding year. Article 82 (security audit) (1) At the request of the Agency, undertakings must submit to a security audit carried out by a qualified independent body, which shall send the results of the audit to the Agency and audited undertaking, retaining the level of confidentiality referred to in Article 79 of this Act. The costs of this audit shall be borne by the undertaking. (2) The undertaking must, for the purposes of implementation of the audit referred to in the preceding paragraph, choose from among one of the independent audit organisations registered with the Slovenian Auditing Institute, and notify the Agency of the audit organisation chosen and of the commencement of the audit procedure within 30 days of the Agency making the request referred to in the preceding paragraph.

Article 83 (measures in the event of emergency situations) (1) In the event of the occurrence of an emergency situation, an undertaking must give precedence to securing the operation of those parts of the network required for the continuity of operation of the networks of entities responsible for the security and defence system and the protection and rescue system. Undertakings must, as required, envisage alternative routes to ensure that network breakdowns are as short as possible. To this end, these measures must be coordinated in advance with the entities responsible for the security and defence system and the protection and rescue system. (2) Undertakings providing public telephone networks must adjust their networks so as to give priority to communications from certain network termination points over communications from other network termination points (hereinafter: priority function). Communications given a priority function in the public telephone network of an individual undertaking shall also retain that priority in the public telephone networks of other undertakings. In emergency situations, undertakings may also give priority to the operation of network termination points so as to restrict or interrupt the operation of other telephone connections. (3) The Government shall, by decree, determine those groups of users with the right to priority network termination points under the preceding paragraph. (4) The Government shall, by resolution, also determine other measures and restrictions or interruptions of operations connected with the provision of public communications networks or services in the event of a natural or other disaster or a catastrophic network breakdown, if this is necessary to rectify the situation that has arisen.
