The practice of securing a computer network from intruders, whether targeted attackers or opportunistic malware, is known as network security.
The goal of application security is to keep software and devices safe against attacks. A hacked application could allow access to the data it was supposed to secure. Security starts throughout the design phase, long before a programme or device is deployed.
Data integrity and privacy are protected by information security, both in storage and in transport.
The processes and decisions for handling and securing data assets are included in operational security.
