Cyber security can be divided into a few common categories.
Network security is the practice of securing a computer network from intruders, whether targeted attackers or opportunistic malware.
Application security focuses on keeping software and devices free of threats. A compromised application could provide access to the data its designed to protect. Successful security begins in the design stage, well before a program or device is deployed.
Operational security includes the processes and decisions for handling and protecting data assets. The permissions users have when accessing a network and the procedures that determine how and where data may be stored or shared all fall under this umbrella.
