Dynamic, Black Box Testing on the Session Traversal Utilities for NAT(STUN).

BeSTORM is the most efficient, enterprise ready and automated dynamic testing tool for testing the security of any application or product that uses the Session Traversal Utilities for NAT (STUN).

Session Traversal Utilities for NAT (STUN) is a lightweight protocol that helps applications discover the presence and types of NATs and firewalls between them and the Internet. It also provides the ability for applications to determine the public IP addresses allocated to them by the NAT. STUN works with many existing NATs. The protocol uses TCP and UDP port 3478. The STUN protocol is a client server protocol: A STUN client which runs on a user’s computer or a network element such as a conferencing server generates and sends requests. A STUN server which is generally attached to the Internet receives STUN requests and sends STUN responses.

BeSTORM specializes in testing the reliability of any hardware or software that uses this network protocol as well as ensuring the function and security of its implementation

By intelligently testing up to billions of combinations of dynamically generated input, BeSTORM ensures the security and reliability of your products prior to deployment. It is also used around the world by government and industry certification centers to ensure that products are secure before purchase and deployment.

Unlike static testing tools, BeSTORM does not require source code and can therefore be used to test extremely complicated products with a large code base. In comparison static source code testing tools must have access to the source code and testing very large code bases can be problematic. BeSTORM also reduces the number of false positives by reporting only actual successful attacks.

BeSTORM uses an approach known as Smart Fuzzing, which prioritizes the use of attacks that would likely yield the highest probably of product failure. These methods of testing are unique compared to older generation tools that use a fixed number of attack signatures to locate known vulnerabilities in products.

In addition, BeSTORM can also be used to test proprietary protocols and specifications (textual or binary) via its Auto Learn feature. This results in a full featured, versatile, and efficient tool that can help your QA team ensure the reliability and security of your software development project.
