With a wide array of security testing solutions, let’s examine how different types of software testing can help organizations achieve security goals.
Software security testing is a type of security testing that aims to reveal loopholes and weaknesses in the security mechanism of applications and systems. When these weaknesses are exploited, the results could include:
Conducting a security assessment is a must if an organization wants to ensure that their customers gain and retain their trust. The prime objective of security testing initiatives is to determine whether an application’s data and resources are protected from potential intruders and if the application is vulnerable to common and sophisticated attacks.
Security testing not only refers to testing the end product for security issues. It also ensures that plenty of proactive assurance techniques are being built in from the beginning of software development. A good security testing practice accounts for security assurance activities such as penetration testing, code review, and architecture analysis as integral elements of the development effort.
A security assessment normally starts by ensuring that the application includes the following attributes:
While security verification (i.e., testing) is an identified phase within the software development life cycle (SDLC), it should be followed throughout the development process. Here’s how to ensure your firm is including security throughout development and implementing critical attributes.
Any piece of software’s development begins with its architecture. A risk assessment should take place on the architecture to make sure security is included from the very beginning. Here are three strategies to enforce early security involvement:
Architecture risk analysis also often includes verification of architecture flaws through source code analysis or penetration testing.
Once the architecture is laid out, developers and engineers can benefit from a developer-friendly static analysis tool which can be easily integrated in SDLC and allows developer to deliver better software, faster. This is also referred to as static application security testing (SAST) and can provide remediation advice earlier in the life cycle, helping resolve vulnerabilities before they become a costly, time-consuming mistake.
Written code can also be scanned with static analysis tools to offer an additional depth to the secure code review processes. Thus, finding and eliminating common and critical software security vulnerabilities within source code.
When an application is ready for quality and assurance testing, it’s also ready for security testing. Dynamic application security testing (DAST) is a type of software testing that uses automated tools to identify common vulnerabilities within running web applications or web services—without the need for source code. This solution is ideal for internally-facing, low-risk applications that need to comply with regulatory security assessments. It can also be used for externally-facing applications; however, using DAST alone will not be sufficient.
Based on the type of application, organizations can also choose from the following manual penetration testing options. Each include client-side and server-side testing capabilities. These assessments can be white box (accompanied by source code), black box (testing without access to source code), or gray box (with some information – like configuration files – but without complete access to source code). Additionally, the duration and depth of analysis can be coordinated on a case by case basis.
The infrastructure is often considered to be one of the most important aspects of maintaining software security. An unpatched piece of software risks exploitation. Leaking sensitive information can, as you probably well know, cause great monetary loss to a firm. Infrastructure testing assists the organization, ensuring that the network is equipped to withstand such issues through the following approaches:
Cloud security reviews are becoming an essential type of software testing as more and more companies deploy their infrastructure on cloud services like AWS, Azure, and Google Cloud. A cloud security assessment starts with understanding of the application’s business and technical context via document review and interviews with key stakeholders. Next, the application’s configuration is reviewed for security gaps, focusing on in-scope services and regions.
Embedded security is different from other types of software testing methods as it is typically specialized for the particular hardware that it runs on. The testing of embedded system includes firmware analysis and hardware security testing. Industries dealing in medical devices, automotive, and avionics commonly utilize embedded devices.
Building reliable software is the usual axiom of the software companies. This also means that the application can protect the data that it handles. There are quite a few types of software testing to choose from. Organizations should strive to understand the kind of security testing that they can benefit from. They should also attempt to prioritize efforts to achieve the level of security required for their industry (at the very least).
