Principles for IT security in the Commission
Article 3
1. IT security in the Commission shall be based on the principles of legality, transparency, proportionality and accountability. 2. IT security issues shall be taken into account from the start of the development and implementation of Commission CISs. In order to do so, the Directorate-General for Informatics and the Directorate-General for Human Resources and Security shall be involved for their respective areas of responsibility. 3. Effective IT security shall ensure appropriate levels of: (a) authenticity: the guarantee that information is genuine and from bona fide sources; (b) availability: the property of being accessible and usable upon request by an authorised entity; (c) confidentiality: the property that information is not disclosed to unauthorised individuals, entities or processes. (d) integrity: the property of safeguarding the accuracy and completeness of assets and information; (e) non-repudiation: the ability to prove an action or event has taken place, so that this event or action cannot subsequently be denied; (f) protection of personal data: the provision of appropriate safeguards in regard to personal data in full compliance with Regulation (EC) No 45/2001; (g) professional secrecy: the protection of information of the kind covered by the obligation of professional secrecy, in particular information about undertakings, their business relations or their cost components as laid down in Article 339 of the TFEU. 4. IT security shall be based on a risk management process. This process shall aim at determining the levels of IT security risks and defining security measures to reduce such risks to an appropriate level and at a proportionate cost. 5. All CIS shall be identified, assigned to a system owner and recorded in an inventory. 6. The security requirements of all CIS shall be determined on the basis of their security needs and of the security needs of the information they process. CIS that provide services to other CIS may be designed to support specified levels of security needs. 7. IT security plans and IT security measures shall be proportionate to the security needs of the CIS. The processes related to these principles and activities shall be further detailed in implementing rules.
