Introduction

Web Application Security is a branch of information security that deals specifically with the security of websites, web applications and web services. With the emergence of Web 2.0 increased information sharing through social networks and other businesses adoption of the Web as a means of doing business on the web has led to increased attacks and as a result, security on web apps has increasingly become of greater importance.

Overview

Security in Web Apps is to determine potential security threats and detect the vulnerabilities in the web application. The majority of the web application vulnerabilities are namely XSS, CSRF, and SQLi.

Why Security Testing?

Security testing is important to establish these basic concepts in Security which are:<

1. Confidentiality – Information should be accessible to only those with authorized access
2. Integrity – A measure intended to allow the receiver to determine that the information which it is providing is correct
3. Authentication – Establishes the identity of the user
4. Authorization – The User should receive a service or perform an action for which he has permission
5. Availability – Information and communication services should be ready at any time, as needed
6. Non-repudiation – Prevent later denial that an action happened

When to start Security Testing?

Network Security testing is usually started once the functionality, integrity and system testing is complete and when the product is about to be released. However, depending on the application and client needs, Security testing can be integrated as a part of CI in order to constantly check for vulnerabilities and make tracking easy.
