The Definition of Network Security and Its Types

Network security defends your network and data against breaches, intrusions, and other attacks.

Network security includes firewalls, antivirus software, and encryption. It also involves monitoring for suspicious activity and user authentication.

Network security is a broad term for protecting your network from internal and external threats.

There are three basic types of network security:


Confidentiality is the secrecy of your data and information.

It means that only the intended recipients should be able to access your data.

If someone else gains access, it’s a breach of confidentiality. An attacker can obtain access to your confidential data by stealing it or reading it over your network.


Integrity is the trustworthiness of your data and information. It means that the data has not been changed or corrupted. 

If an attacker modifies your data, it creates a breach in integrity. Malware, hackers, and viruses can change or destroy your data without you even knowing it.


Availability is the guarantee that your network and its services are available when you need them. 

If attackers shut down or disable your network, this is a breach in availability. Denial-of-service (DoS) attacks are one way to take down a system for an extended period.
