Testing Multi-Tenant SaaS Platforms Without Disrupting Customers

Even if a developer team follows secure coding standards and keeps dependencies up to date, they are still able to ship software with a vulnerability. The reason is simple: real attacks are rarely based on the checklist. An attacker could combine an inadequate authorization rule with an exposed API endpoint, abuse the process of resetting passwords, or discover that one customer account can access the data of a different tenant.

Professional penetration testing Brisbane businesses use for security assurance looks at systems from that adversarial perspective. Instead of asking if security controls are in place, expert testers investigate whether the controls can actually be bypassed.

The distinction is significant the most Australian organisations that deal with sensitive assets such as medical records, financial information customer data, financial records or other assets with a high degree of security.

The automated scanning process only tells a small portion of the truth

Vulnerability scanners prove useful. They can spot outdated software, unsecure headers, and CVEs as they also identify obvious issues with configuration. They do not comprehend how an application should behave.

Imagine a portal for customers that lets customers change their account number with the request process, as well as access invoices from an additional company. A scanner isn’t likely to detect something unusual when the server provides perfectly valid results. Human testers can detect the failure of authorization immediately.

Web penetration testing is a blend of manual investigation and automation. Testing examines authentication, sessions and access controls as well as injection risk, API behaviors, configuration issues and business processes.

SaaS-based systems raise questions about security

Testing cloud applications that are multi-tenant is especially important, because errors can impact multiple clients at one time.

Saas penetration tests must include tenant isolation, API authorizations, role changes and account recovery. Additionally, they should analyze integrations with other external services including account recovery, data exposure and API authorization. The tester should not only check if the feature is functional, but also if it can be used in a way that was never intended by the creator.

If a user has been assigned an account that does not have administrative capabilities the user may not find them on the interface. However, this doesn’t mean that the API will stop them from calling directly. Testing is essential in order to distinguish this instead of just looking at the screen.

Web applications that are modern and mobile are more vulnerable to attack

Applications of today often combine JavaScript front-ends and APIs, cloud service providers, identity providers and microservices. There may be weaknesses in any component, as well in the trust relationship that exists between the two.

The connections are then monitored by a thorough penetration test. Testing may include examining the way tokens are generated, whether sensitive endpoints enforce the authentication process consistently, or what data that is managed by the user is transferred between the various services.

Siege Cyber is an expert in this kind of testing for applications. They are able to work with the latest frameworks such as APIs and cloud-hosted platforms, and they also test complicated application architectures.

This report is an excellent tool that can help developers to find the solution.

In the end, finding vulnerabilities is only half the task. When engineers are able to replicate an issue, recognize the risk, and then confidently address the issue, security testing is extremely valuable.

Siege Cyber reports contain evidence reproducibility steps, as well as risk rating. They also provide impact analyses with practical remediation recommendations, and a thorough analysis of the impact. Technical teams receive the details necessary to correct the issue while stakeholders from the business receive an executive-level overview of the risk. There is the option to increase the importance of conclusions during the engagement rather than waiting for the final reports.

The testing after remediation gives another layer of security by confirming that the initial flaw has been fixed without introducing another one.

Companies that require independent verification, proof of compliance, or increased confidence prior to release may gain by conducting penetration tests. It provides a controlled setting to observe how an attacker who is skilled could take on the system. It is vital to identify the solution before the attacker.
