Network security vs Information Security.
Network security is a process that consists of the protection of the internet and the information that goes through it. It’s about controlling access to information and devices in order to prevent unauthorized access.
Information security, on the other hand, is about protecting information from unauthorized access. Also,nformation security involves encryption and other methods of securing data.
Information security is a subset of network security, but network security is much broader than information security.

Information Security vs Network Security: What’s the difference?
If you are in Information Technology (IT) networking or cyber security, you may have come across “information security” and “network security”. You may have even wondered what the difference between these two concepts is.
Information Security: What is it?
Information security refers to any action taken to protect data from unauthorized access and modification. Hence, information security can be for different levels: people, processes, applications, and hardware/software systems. Information technology professionals who specialize in information security are called “information security officers” (ISOs). They ensure that sufficient protection is implemented on all levels in order to prevent unauthorized access to or modification of vital data in their organization or company.
Network Security: What is it?
By contrast, network security refers to any action taken to protect networks from unauthorized access and modification. Network security can be applied at different levels: people, processes, software/hardware systems, etc. Network systems administrators that specialize in network security are called “network engineers” (NAS). They design and implement necessary protection at various levels of their organization or company in order to prevent unauthorized access to and modification of vital data on the network(s).
Similarities of Network Security and Information Security
1. The fundamental purpose of both network security and information security is to protect data. Data includes all the information in your computer, in your company’s computers, and on your company’s network. Network security and information security are both about preventing unauthorized access to or modification of vital data.
2. Another common goal of both network security and information security is the confidentiality of data. Confidentiality, as applied to data, means that only authorized users can access the data, and no one else is able to get access to it. In order to achieve confidentiality of data, network and information security professionals employ encryption. Encryption scrambles the data in such a way that only those with the decryption key can read it.
3. In order to implement confidentiality, network and information security professionals have to focus on controlling access to their organization’s resources in two ways: authentication and authorization, which are closely related concepts. Authentication refers to confirming an identity, while authorization refers to determining what a user can do with a resource based on his/her identity (i.e., after authentication).
4. Network security professionals typically use physical security measures at perimeter points of their organizations’ networks in order to control access to those networks. Physical measures include firewalls (protecting the network from unauthorized intrusion) and other types of hardware/software firewalls that protect specific things on their networks (such as web servers or databases). They also use logical security measures at various points along their networks (such as routers) in order control access based on the destination IP address or port number (i.e., protecting specific services or applications).
