This study investigates the tradeoff between security and the usability or performance of multimedia services in the case of a software-based network intrusion detection system and uncompressed video transmissions. Uncompressed video transmissions are especially interesting in this context as they are not subjected to jitter and delays caused by compression mechanisms and can therefore be expected to be more robust when it comes to added delay variations and subsequent distortions stemming from security devices. The paper focuses on the special case where video is protected by Forward Error Correction mechanisms, which allow reordering of the original packet sequence after it may have been altered by network impairments. Various Forward Error Correction mechanisms are applied in the presence of a network intrusion detection system and its impact on the resulting video quality is investigated. © 2010 IEEE.
