What Is WebAplication security ?

WEB APPLICATION SECURITY

    Web application security (often referred to as Web AppSec) is the concept of designing websites to function normally even when they are attacked. The notion is integrating a set of security measures into a Web application to protect its assets from hostile agents. 

    Web applications, like all software, are prone to flaws. Some of these flaws are actual vulnerabilities that can be exploited, posing a risk to businesses.Such flaws are guarded against via web application security. 

    It entails employing secure development approaches and putting in place security controls throughout the software development life cycle (SDLC), ensuring that design flaws and implementation issues are addressed.



Why is web security testing important? 

  • The goal of web security testing is to identify security flaws in Web applications and their setup.
  •  The application layer is the primary target (i.e., what is running on the HTTP protocol).
  • Sending different forms of input to a Web application to induce problems and make the system respond in unexpected ways is a common approach to test its security.
  • These so-called "negative tests" look to see if the system is doing anything it wasn't built to accomplish.
  • It's also vital to realize that Web security testing entails more than just verifying the application's security features (such as authentication and authorization).
  •  It's also crucial to ensure that other features are deployed safely (e.g., business logic and the use of proper input validation and output encoding).
  • The purpose is to make sure that the Web application's functions are safe. 



         The Top 10 Web Application Vulnerabilities 

 

  1. Injection

  2. Broken authentication

  3. Sensitive data exposure

  4. XML external entities (XXE)

  5. Broken access control

  6. Security misconfigurations

  7. Cross Site Scripting (XSS)

  8. Insecure deserialization

  9. Using components with known vulnerabilities

  10. Insufficient logging and monitoring

Who is pentester ?

  Penetration Tester Overview A penetration tester is a network security expert who attempts to break into or discover potential exploits in various computer systems and software.They can be thought of as a form of ethical hacker.They are typically expected to conduct a number of tests, most of which are focused on network penetration, and then write up evaluation reports based on their findings. While they will frequently conduct pre-determined sorts of tests, they will also develop their own tests for a significant amount of the time, which demands creativity and inventiveness, as well as a high level of technical understanding and know-how.    You'd be expected to conduct formal tests on web-based apps, networks, and other sorts of computer systems on a regular basis as a penetration tester.Physical security inspections of servers, computer systems, and networks will also be expected of you.You'll be conducting regular security audits from both a logical/theoretical an...

Improve Your Web Application Security

HOW TO IMPROVE WEB APPLICATION SECURITY      Robust security measures must advance in tandem with web application technologies. Web app security threats are real and happening all over the world. To protect against emerging threats, standard measures are no longer sufficient. Fortunately, apps do not have to remain vulnerable, waiting for bad actors to abuse them. To safeguard this ever-increasing attack surface, robust security procedures and practices can be implemented. How to Improve Web Application Security  Choose a secure host Secure your login pages using SSL (HTTPS) encryption  Always sanitize and validate user input Have a good password policy  Limit access rights and credentials Keep your website clean Ensure everything is up to date Keep regular backups Make sure to tweak the default settings of your CMS Run security tests on your website for vulnerabilities             Sometimes the most straightforward approa...

What is web application ?

WEB APPLICATION  What is WEB APPLICATION ? In today’s world, the usage of web applications growing day by day. The professionals of software area like Software Developer and Software Testers need to have familiar with Web Applications. It is a client-server application program, stored on a remote server that uses web browsers and web technology to perform specific function over the Internet through a browser interface. As said above, It is a client-server application program, therefore in the client-server environment, multiple computers can share information like saving the information into a database. The “client” can be used to enter the information, and the ‘server’ is used as storage for the information.   How do web applications work? A typical web application workflow looks like the following:   A user submits a request to a web server over the internet, either through a web browser or through an app's user interface. The webserver send...
