Importance of Software Security Testing

Security testing has a distinct relationship with software quality. Just because software meets quality requirements related to functionality and performance, it does not necessary mean that the software is secure. A security measure which protects against the disclosure of information to parties other than the intended recipient that is by no means the only way of ensuring the security. The most effective way to achieve secure software is for its development life cycle processes to rigorously conform to secure development, deployment, and sustainment principles and practices. Security testing is a process to determine that an information system protects data and maintains functionality as intended. A measure intended to allow the receiver to determine that the information which it is providing is correct. Software testing has focused on making sure systems satisfy requirements. Such functional requirements and specifications are expected to, but may not necessarily, accurately depict the functionality actually wanted by prospective users, particularly those aspects users may not be aware of or may not have been asked to consider.

Software security testing services helps in identify implementation errors that were not discovered during code reviews, unit tests, or security white box tests, discover security issues resulting from boundary conditions not identified during the design and implementation phases, uncover software security issues resulting from incorrect product builds, or the interaction with the underlying environment and verify that software security components and security-specific sub-systems are operating properly. Security is always relative to the information and services being protected, the skills and resources of adversaries, and the costs of potential assurance remedies; security is an exercise in risk management. Risk analysis, especially at the design level, can help us identify potential security problems and their impact. Once ranked and identified, software risks can then help guide software security testing. Security testing must necessarily involve two diverse approaches: Security testing involves determining who should do it and what activities they should undertake. Testing security mechanisms to ensure that their functionality is properly implemented, and performing risk-based security testing motivated by understanding and simulating the attacker’s approach.
