网络安全
顾名思义,网络安全是组织或专家为保护设备,计算机网络或数据免受恶意活动而采取的一种过程或措施。它被认为是减轻网络犯罪的补救措施之一。简而言之,它是指确保数据安全。即使面对网络威胁,它也可以保持安全稳定的业务运营。

密码学
顾名思义,密码学是一个主要用于加密和解密未经授权访问无法解密的数据或消息的过程。它部署了加扰或失真的符号。它仅用于提供额外的安全性,以确保只有授权用户才能理解该消息。简而言之,它是指用于保护敏感信息的方法。

网络安全和密码学之间的区别:

Cyber Security 

Cryptography  

It is a process of keeping networks, devices, programs, data secret and safe from damage or unauthorized access.   It is a process of keeping information secret and safe simply by converting it into unintelligible information and vice-versa.  
It is all about managing cyber risks in all aspects such as people, process, technology, etc. It is all about math functions and can be applied in technical solutions for increasing cybersecurity.  
Its main objective is to prevent or mitigate harm or destruction of computer networks, applications, devices, and data. Its main objective is to keep plain text secret from eaves or droppers who are trying to have access to some information about the plain text. 
It is generally used for the protection of internet-connected systems like software, hardware, and data, risk management, disaster planning, access control, policies.    It is generally used for integrity, entity authentication, data origin authentication, non-repudiation, etc.  
It protects the system against viruses, worms, unwanted programs, etc., protects the computer from being hacked, reduces computer freezing and crashes, provides privacy to users, etc.  It protects authentication and data across devices, maintains integrity, provides privacy to its best, allows two parties to communicate securely, etc.  
It makes cryptography one of its subsets and uses it to design algorithms, ciphers, and security measures that usually codify and keep company and customer data protected.  It is an automated mathematical tool that is used to enhance and improve cybersecurity. 
It generally involves the implementation of specific procedures to keep data safe.   It generally mitigates or reduces cyber-crime simply by using elaborate design to encrypt messages.
