Web App: Definition

A Web application or Web app is an application program stored on a remote server and delivered over the Internet via a browser interface. It refers to any program that is accessed over a network connection using HTTP instead of existing within a device's memory. Web-based applications mostly run within a web browser. However, they can also be client-based, where a small part of the program gets downloaded to a user's desktop, but processing is performed over the internet on an external server.

Web App Definition

A web app relieves the developer of the responsibility of developing a client for a specific operating system or a particular type of computer, allowing anyone to use the application as long as they have internet access. Web applications mostly use a combination of client-side script (HTML, Javascript, etc.) and server-side script (ASP, PHP, etc) to develop the application. The server-side script deals with all the hard stuff like storing and retrieving the information, and the client-side script deals with the presentation of the information.

Web App Security

Web application firewalls (WAFs) are software and hardware solutions used for protection from application security threats. These solutions have been specifically designed for examining incoming traffic to block attack attempts, thus compensating for any code sanitization deficiencies. WAFs use different heuristics to determine which traffic is given access to an application and which needs to be cleared out. Typically, WAFs are combined with other security solutions to develop a security perimeter. These could include distributed denial of service (DDoS) protection services that offer additional scalability required in order to block high-volume attacks.

Besides the efficient security provided by WAFs, there are several methods for securing web applications. The following processes will have to be part of any web application security checklist:

  • Authorization: Test the application for path traversals; horizontal and vertical access control issues; insecure, direct object references; and missing authorization.
  • Cryptography: Secure all data transmissions. Check if specific data has been encrypted and also whether weak algorithms been used. Also, check if randomness errors exist.
  • Denial of service: Improve an application's resilience against denial of service attacks by testing for account lockout, anti-automation, HTTP protocol DoS and SQL wildcard DoS.
  • Information gathering: Manually review the application, detect entry points and client-side codes, and classify third-party hosted content.
