- Network security
Network security is the process of protecting a computer network from attackers, whether targeted attackers or opportunistic malware.
- Application Security
Application security is about keeping software and devices safe. A compromised application can provide access to data that is intended to be protected. Successful security begins at the design level, long before a program or device is implemented.
- Information security
Information security protects the integrity and confidentiality of data during storage and transmission.
- occupational safety
Business security involves the processes and measures used to manage and protect data assets. Both the permissions that users have when accessing the network and the procedures that determine how data is stored and where it can be stored or shared fall under this umbrella
- Disaster recovery and business continuity
Disaster recovery and business continuity describes how an organization responds to a cybersecurity incident or other incident that results in loss of operations or data Disaster recovery plans describe how an organization restores its business and information return to pre-event operating capacity. Business continuity is a system that an organization falls back on when trying to operate without certain resources.
- End-use education
End-user education addresses the most unpredictable element of cybersecurity: people. Anyone can accidentally introduce a virus to an otherwise safe system by not following good security practices. It teaches users to delete suspicious email attachments, not to insert unknown USB drives, and other sensitive items
