strategic, legal, regulatory and technical aspects of cyber security with the involvement of foreign colleagues and counterparts The importance of Cyber Security for state and global security is recognized by every nation. Countries that strive for technological development are responsible to the society to protect its own cyber space, provide its security and dynamic progress. Large-scaled cyber-attacks experienced by Georgia in 2008-2011 highlighted the necessity for elaboration of Cyber Security Policy in order to provide safe and credible functioning of critical information systems. In 2013 with the support of the NATO Liaison Office in Georgia, the working group of the Ministry of Defence of Georgia studied the existing situation in cyber security in the MoD. Cyber security core problems and challenges were identified: there were no cyber security threat/risk monitoring, analysis and prevention tools available in the MoD. Since cyber security assurance in Defence forces has its specificity, Cyber Security Bureau was established within the system of Ministry of Defence in 2014. Establishment of Cyber Security Bureau was preceded by the NATO Liaison Office supported Roadmap summarizing existing situation, threats and challenges related to cyber-defence within the system of the Georgian Defence Ministry. This Document identified cyber security gaps and discrepancies in Georgian defence sector and recommended creation of the agency that would be focused on cyberdefence issues in Georgian Defence Forces. Georgian authorities took into consideration recommendations provided by NATO Liaison Office and thus CSB was created. Bureau is responsible for handling cyber incidents directed against information systems of the Georgian Defence Forces on 24/7 basis as well as ensuring installment of secure cyber connections inside defence sector. Cyber Security Bureau also prescribes information security standards withinGeorgian defence sector and elaborates relevant binding legal acts, responds cyber incidents directed against Ministry of Defence through CSIRT (Computer Security Incident Response Team). In 2014, CSB with cooperation of NATO Liaison Office of Georgia developed Cyber Security Policy Document for 2014-2016. This keynote document was designed to be used as a basis for various strategies and guidelines that orient to actions towards establishing and enhancing cyber security. It must be continuously evaluated and updated due to dynamic changes and impacts in cyber space. The Policy fully responds to global challenges in cyber space and complies with principles of NATO and the EU countries in the field of cyber security. The Policy defines core approaches and priorities of the MoD and provides all strategic objectives in the field of cyber security the execution of which will significantly contribute to the MoD to work and act in a safe, effective and resilient environment and ensure confidentiality, integrity and availability of information systems. This constitutes solid basis for National Security. On the basis of the “Cyber Security Policy” was elaborated “Cyber Security Development Action Plan”, which represents the core document of Cyber Security Bureau for 2017-2021 to implement and develop cyber security in the defence sector, describing the actions, steps and methods necessary for attaining the goals set forth in Cyber Security Policy.
