Video conferencing is a communication medium which offers a global communication platform for organizations and institutions to fulfil their communication requirements.Due to usage of video conferencing for different purposes such as e-learning and management meetings, the security and confidentiality of information, protection of systems against various security attacks and protection against internal malicious users who exploits the vulnerabilities has become substantial and is a main concern for the usage of video conferencing system.In order to have a secure communication environment, mitigate the security issues and meet security principles like confidentiality, integrity and accountability specific security requirements and best practices have been defined. Nonetheless, regardless of all these specific security requirements lack of technical knowledge, security issues awareness and behaviour issues can cause the businesses to face information security incidents and sensitive business information to be accessed by hackers.In this thesis, we discussed the findings of a web-based questionnaire aimed at determining the awareness level of IT personnel (who implement the security policies and responsible for setting and security of the systems) in terms of security recommendations and guidelines of video conferencing systems based on awareness dimensions (knowledge, attitude, behaviour). The primary motivation was to know the level of awareness as one of the key reasons behind the security breaches in video conferencing systems. This approach has recognized security matters which are needed to be promoted.The data obtained in this awareness test can be utilized for educational and training purposes in security awareness programs related to video conferencing systems.
