What is the Difference Between Network Security and Information Security?

🆚 Go to Comparative Table 🆚

The main difference between network security and information security lies in their scope and focus. Here are the key distinctions:

  • Network Security focuses on protecting the usability and integrity of a network and the data transmitted over it. It deals with securing computer networks from unauthorized access, loss, and damage. Examples of network security measures include firewalls, network segmentation, remote access VPN, email security, intrusion prevention systems (IPS), and data loss prevention (DLP).
  • Information Security has a broader scope, as it covers the protection of all types of information, regardless of the means of transmission. It ensures the confidentiality, integrity, and availability of data, whether it is in physical or digital form. Information security involves protecting data from unauthorized access, disclosure, disruption, modification, or destruction. It includes various aspects such as data classification, access control, encryption, and data retention policies.

In summary, network security is a subset of information security that specifically focuses on protecting data transmitted over networks, while information security encompasses a broader range of measures to protect all types of information and their means of transmission.
