Network security encompasses the policies, processes, and practices adopted to prevent, detect, and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources. It involves the authorization of access to data in a network, which is controlled by the network administrator. In essence, network security aims to secure the confidentiality, integrity, and availability of data and network infrastructure. As our world becomes increasingly interconnected, the importance of robust network security measures cannot be overstated, forming the first line of defense against a myriad of cyber threats that can have devastating consequences for individuals, businesses, and governments alike.
