network security and cryptography

Information technology (IT) security includes a variety of factors, two of the most essential of which are network security and cryptography. Network security aims to prevent illegal access to the network and interference with its operation.

What exactly does “Network Security” mean?

The term “network security” refers to the precautions taken to prevent unauthorized access to or improper usage of data and machines connected via a network. Cryptography is an essential part of the security infrastructure of networks. It enables ways to maintain confidentiality, integrity, and authentication. In addition, safeguards are in place to protect the network’s infrastructure against intrusion, including routers and switches.

What Exactly is Cryptography?

Cryptography is the practice of keeping one’s conversations private even when others are present, and the term refers to both the technique and the term itself. Numerous applications, such as email, file sharing, and encrypted conversations, use cryptography to provide privacy and prevent unauthorized access. Encryption and decryption of data are the two primary functions of the field of cryptography, a mathematical discipline.

Cryptography used to prevent unauthorized access to information and maintain the confidentiality of communications. Regarding network security, cryptography used to safeguard data from being spied upon by unauthorized parties and to assure the validity of conversations. 

The unauthorized use of content that is protected by intellectual property rights can also be prevented with the help of cryptography. The use of cryptography is essential to ensure the safety of information systems.

Cryptography used to safeguard data while it is at rest and while it is in motion. Data stored on a device, such as a hard disc, a USB drive, or an SSD considered data at rest. Network transfers the data, whether it Internet, a private network, or a wireless network, considered as data that “in transit.”

What Is the Difference Between Cryptography and Network Security?

Cryptography is the art and science of securely communicating secret information when other people are present. The practice of cryptography falls under the umbrella term of network security. Cryptography is utilized to prevent illegal access, modification, or destruction of information communicated over networks.

On the other hand, network security refers to the procedures taken to secure the availability, confidentiality, and integrity of data and systems over a network.

Data protects both while it is moving via the network and stored. These technologies also assist in identifying and mitigating assaults made against computer systems and their associated data.

Encrypting data before saving it on a computer or transferring it over a network enables cryptography. It provide security for data that not actively used or transmitted. Network security protects the data in transit technologies such as encryption and firewalls. Encryption used to encode data before sending it over a network. While firewalls used to block access to sensitive areas of a network.

On the other hand, cryptography used to safeguard information, while network security technologies protect systems and data. This is one of the most critical distinctions that made between network security and cryptography.

Cryptography safeguards communications, whereas network security concentrates on defending computer systems. The use of cryptography to secure individual communications and network security technology to guard an entire system are two uses of the term “protect.” Cryptography is also utilized for authentication, whereas network security technology is employed for authorization reasons. 


In this article, we discussed the distinctions between network security and cryptography. We examined the functions of each, as well as the reasons why one cannot be substituted for the other. 

After this article, it is our aim that you gain a deeper comprehension of the operation of the technologies. As mentioned earlier, and a better grasp of some of the terminology utilized in the field.
