1. Application Security :
Application Security, as name suggests, is a security program that directly deals with applications themselves. Its goal is to identify, rectify, and correct security issues in applications within organization. It is totally based upon identifying and fixing vulnerabilities that correspond to weakness or CWEs. Its testing also reveals weakness at application level that help to prevent attacks.
2. Network Security :
Network Security, as name suggests, is a security program that is all about securing assets and scanning traffic at network level. Its goal is to secure access to devices, systems, and services. It also means maintaining solid defense that involves physical and software-based firewalls, Intrusion Prevention Systems (IPS), etc. It simply helps to protect workstations from harmful spyware and ensures that shared data is kept secure.
Difference between Application Security and Network Security : Application Security Network Security
It is type of security provided to apps simply by finding, fixing, and preventing security vulnerabilities. It is type of security provided to network from unauthorized access and risks. Its main goal is to make app more secure and prevent data or code from being stolen or hijacked. Its main goal is to take physical and software preventative measures to protect underlying networking infrastructure. It makes application more secure, keep confidential information safe and secure, reduces risks from both internal and third-party sources, protects sensitive data from leaks, etc. It makes network more secure, protects proprietary information, reduce risks of data loss, theft and sabotage, build trust, etc. Tools used for application security includes SAST, DAST, IAST, etc. Tools used for network security includes Wireshark, AirCrack, Metasploit, etc. It relies on how applications operate and looks for anomalies in those operations. It relies on ability to scan traffic on enterprise network. It is generally remediated or corrected by Programmers. It is generally remediated or corrected by Network Admins. It includes business logic security issues. It includes integration issues. Its key features include authentication, authorization, logging, encryption, and application security testing. Its key features include perimeter security, data privacy, security monitoring, policy management, etc. It is a process of developing, adding, and testing security features within application to prevent security vulnerabilities. It is a process of preventing unauthorized activity across given networking infrastructure.
