Black Box Security Analysis and Test Techniques

Black box techniques are the only techniques available for analyzing and testing non-developmental binary executable without first decompiling or disassembling them. Black box tests are not limited in utility to COTS and other executable packages: they are equally valuable for testing compiled custom developed and open source code, enabling the tester to observe the software’s actual behaviors during execution and compare them with behaviors that could only be speculated upon based on extrapolation from indicators in the source code. Black box testing also allows for examination of the software’s interactions with external entities (environment, users, attackers)—a type of examination that is impossible in white box analyses and tests. One exception is the detection of malicious code. On the other hand, because black box testing can only observe the software as it runs and “from the outside in,” it also provides an incomplete picture. Read more


Black Box Security Testing

Black box testing is generally used when the tester has limited knowledge of the system under test or when access to source code is not available. Within the security test arena, black box testing is normally associated with activities that occur during the pre-deployment test phase (system test) or on a periodic basis after the system has been deployed.

“White Box” Techniques for security testing

White box” tests and analyses, by contrast with “black box” tests and analyses, are performed on the source code. Specific types of white box analyses and tests include:

Static Analysis

It is known as “code review,” static analysis analyses source code before it is compiled, to detect coding errors, insecure coding constructs, and other indicators of security vulnerabilities or weaknesses that are detectable at the source code level. Static analyses can be manual or automated. In a manual analysis, the reviewer inspects the source code without the assistance of tools. Read more

When to perform Software security analysis and tests?

Most of the software security practitioners would agree that the common practice of postponing security analysis and tests after the software implementation phase and even after it has been deployed (i.e., during its acceptance phase), makes it extremely difficult to address in a cost-effective, timely manner any vulnerabilities and weaknesses discovered during the analysis and testing process.

What is the software security testing?

Secure Software

In the Software industry, Most of the clients have a main requirement which is “we want the system to be secured”. Security is a non-functional property of the system, the main goal for securing the system to make this system dependable. So, we can depend on this system and it can perform its excepted functions as required and specified.

Therefore, it is mandatory to run the security testing procedures to ensure that we can depend on this system, but we need also to consider some functional requirements on writing requirements specifications document that help to obtain this goal. Read more

What did they say about Software security testing?

“Over 70 percent of security vulnerabilities exist at the application layer, not the network layer” Gartner.

Hacking has moved from a hobbyist pursuit with a goal of notoriety to a criminal pursuit with a goal of money” Counterpane Internet Security.

“64 percent of developers are not confident in their ability to write secure applications” Microsoft Developer Research.

“Losses arising from vulnerable web applications are significant and expensive – up to $60 billion annually”IDC/IBM Systems Sciences Institute.

“If 50 percent of software vulnerabilities were removed prior to production use, enterprise configuration management and incident response costs would be reduced by 75 percent each.”Gartner.
