The Telecommunications and Network Security domain encompasses the practices and technologies used to secure telecommunications and networking systems. The Information Systems Security tenet of Availability refers to the ability of authorized users to access the necessary resources and data in a timely and reliable manner.
Of the options provided, the answer that directly affects the tenet of Availability is Network availability (option B). Network availability refers to the ability of a network to remain operational and accessible to authorized users, despite any potential disruptions or downtime.
In order to ensure network availability, security administrators must employ various measures to prevent, detect, and respond to potential threats and incidents that could impact network performance or availability. These measures may include the use of redundancy and failover systems, as well as proactive monitoring and maintenance of network infrastructure.
Netware availability (option A) may refer specifically to the availability of Novell Netware networking software, which is no longer widely used. Network acceptability (option C) and network accountability (option D) do not directly relate to the tenet of Availability. Network acceptability may refer to whether a network meets certain standards or criteria, while network accountability may refer to the attribution of responsibility or liability for network-related activities.
