Testing Multi-Tenant SaaS Platforms Without Disrupting Customers

Even if the development team adheres to secure coding standards and keeps dependencies up to date, they are still able to create software that is insecure. The reason is simple: real attacks rarely follow the guidelines of a checklist. An attacker may mix a weak authorization with an exposed API or misuse a procedure for resetting passwords, or realize that the data of one tenant is access by a different.

Professional penetration testing Brisbane companies use to test security assurance analyzes systems from that adversarial perspective. Professionally tested testers don’t question whether security measures are in place, but whether they are able to be bypassed.

This difference is important for Australian companies which handle sensitive information, such as customer data, financial records, healthcare records, or any other assets.

The automated scanning process is only part of the story

Vulnerability scanners are useful. They can identify old software, insecure headers and CVEs as well as obvious configuration issues. What they are not able to understand is the way an application is supposed to behave.

Think about a portal for customers where users can change their account number in a request and retrieve another invoices from a company. The server could deliver perfectly valid results, so the automated scanner will not find anything unusual. A human tester recognizes the problem immediately.

Automated web penetration testing combined with manual investigation is the secret to an effective test. Testing focuses on authentication, session and access controls in addition to injection risks, API behaviors, configuration weaknesses and business processes.

SaaS environments pose their own security concerns

Multi-tenant cloud services require be tested with care because a mistake can impact many customers at the same time.

Effective Saas penetration testing should examine tenant isolation, privileged functions, API authorization, role changes, account recovery, data exposure, and integrations with external services. Testers must understand not just whether a feature works, but whether it is possible to manipulate it in a way the development team would never have intended.

If a user is given a role that does not include administrative features however, they might not be able to see them in the interface. However, that doesn’t mean the core API hinders them from calling it directly. Active testing is needed in order to distinguish this instead of simply looking at the screen.

Modern web applications offer an increased attack surface

Today’s applications often combine JavaScript front-ends APIs, cloud service, APIs identity providers, microservices and third-party integrations. Each component, and the relationship of trust between them, could have weaknesses.

These connections are completed by a thorough penetration test. Testing can include checking how tokens are generated and whether secure endpoints require authentication on a regular basis, or how data managed by the user is transferred across services.

Siege Cyber is specialized in this type application testing. It is able to work with the latest frameworks and APIs as well as cloud-hosted applications and intricate architectures.

The report will help the developers to fix the issue.

In the end, finding vulnerabilities is only part of the process. Security testing offers the most value when engineers can replicate the problem, comprehend the danger, and fix it confidently.

Siege Cyber reports contain evidence of reproduction, steps to reproduce and risk rating. They also provide analysis of impact, practical remediation advice, and a comprehensive analysis of the impact. The business stakeholders receive an executive explanation of the risk, while technical teams get the detail needed to resolve the issue. Important findings can also be addressed during the engagement instead of waiting for the report to be completed.

Testing after remediation provides another layer of security by confirming that the original weakness has been fixed without introducing an entirely new issue.

Penetration testing can be a useful tool for organizations that are looking to test their systems, demonstrate compliance, or build confidence prior to the release of a major version. Tools and policies don’t offer this, but it gives them a method to determine how a skilled hacker might approach the software. It is vital to identify the answer before the attacker.
