Even if a team of developers adheres to strict coding guidelines and keeps dependencies up to date, they can still create software that is insecure. The truth is that real attacks are rarely based on a checklist. An attacker might combine a weak authorization with an unprotected API, misuse a workflow to reset passwords or learn that data from one tenant could be accessed by another.
Companies that are located in Brisbane employ penetration testing professionals to ensure security. They evaluate systems through the adversarial lens. Instead of determining whether security measures are in place, experienced testers ask whether those controls are actually able to be manipulated.
The distinction is important in Australian organisations that deal with sensitive assets such as financial information, healthcare records and customer information, among other assets with a high degree of security.
Automated scanning only tells part of the truth
Vulnerability scanners may be helpful. They are able to identify outdated software, unsecure headers, and CVEs, as well as obvious issues with configuration. What they are not able to understand is what an application’s intended to behave.
Imagine a customer portal which allows customers to alter their account number within a single request, and then obtain invoices from a different business. The scanner could not spot anything suspicious if the server provides perfectly valid results. Human testers can spot the problem with authorization in a flash.
Quality web penetration testing combines automation with manual investigation. Testers analyze authentication sessions, session, access controls, injection risks, API behavior, vulnerabilities in configuration as well as business processes looking for combinations of flaws that can have an impact.
SaaS environments pose security issues of their own
Multi-tenant cloud applications need extra attention when testing, as a single error can result in a massive impact on many users at one time.
Effective Saas penetration testing should focus on tenant isolation, privilege functions, API authorization, role changes, account recovery, data exposure and integrations with external services. The tester should not just check if the feature is functional, but also if it can be used in ways that was never intended by the developer.
If a user has been assigned a role that does not include administrative capabilities, they may not find them on the interface. This does not mean that the API does not allow them to making calls directly. It is crucial to check the API, rather than just observing what appears to be the API.
Modern web applications have a greater attack surface
Today’s applications combine JavaScript front end APIs, cloud services and APIs. Additionally, they include integrations from third parties. There could be flaws in each component, as depending on the trust that exists between them.
These connections are completed by a thorough penetration test. Testers can examine the method of how tokens are issued as well as whether the endpoints are able to ensure authorization in a consistent manner, how user-controlled data moves between services, and whether it is possible for a flaw with a low risk to be coupled with a weakness to cause a significant security breach.
Siege Cyber is specialized in this kind of application testing. It is able to work with the latest frameworks and APIs as well with cloud-hosted apps and complicated architectures.
The report will guide developers to fix the problem
The process of identifying vulnerabilities is only half of the work. The most effective security testing is when engineers are able to reproduce and understand the problem, and also remediate the risk.
Siege Cyber reports contain evidence of reproduction, steps to reproduce and risk rating. They also contain analysis of impact, practical remediation advice, and a thorough analysis of the impact. Business stakeholders are provided with an executive explanation of the vulnerability while technical teams are provided with the detail needed to resolve the issue. Important findings can be made public during the process instead of waiting for the final report.
Retesting after remediation adds an additional layer of security by verifying that the original flaw has been corrected without introducing a new vulnerability.
For those who want independent validation, evidence of compliance, or greater confidence before a major release Penetration testing can provide something the automated tools and policies can’t be able to provide: a controlled chance to find out how skilled attackers could actually approach the system. Discovering the answer before an actual adversary does is what makes the exercise valuable.
