The document outlines the goals of network security which are confidentiality, integrity, and availability. Confidentiality aims to hide data from unauthorized people through encryption. Integrity seeks to prevent unauthorized modification of data using hashing. Availability aims to prevent loss of access to resources for authorized users by developing efficient network design, preventing malicious activity like DDoS attacks, ensuring sufficient bandwidth, and removing duplex mismatches. The document was presented by an instructor from the Faculty of Computer Science at Kabul Education University to discuss network security goals and methods.
