Testing Multi-Tenant SaaS Platforms Without Disrupting Customers

Even if a developer team follows secure coding standards and keeps dependencies up to current, they could still ship software with a vulnerability. Real attacks don’t follow the guidelines of a checklist. An attacker may combine an untrue authorization rule coupled with an exposed API endpoint, abuse an automated process to reset passwords or even discover that a customer account has access to other tenant’s information.

Security assurance Brisbane companies use penetration testing that looks at systems from an adversarial angle. Instead of asking if security measures are in place, experienced testers ask whether those controls are actually able to be manipulated.

For Australian companies that handle customer information and financial data, as well as healthcare records, or other sensitive assets, that difference is important.

Automated scanning can only tell a part of the tale

Vulnerability scanners are very useful. They are able to identify outdated software, unsecure headers, and CVEs, as well as obvious configuration issues. However, they are not able to grasp the way an application functions.

Imagine a customer portal that allows them to view invoices of a different business and also change their account number. The server can deliver perfectly valid results, so an automated scanner may not see anything unusual. A human test-taker can identify the problem immediately.

Quality web penetration testing combines automation with manual investigation. Testers look for flaws in session and authentication API behaviour and configuration and access control as well as injection risk API behavior.

SaaS environments pose security concerns of their own

Multi-tenant cloud apps require extra caution in testing, since a single mistake can have a large impact on many users at once.

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 needs to not just know if the feature is functioning and if it can be manipulated in a manner that the developers didn’t intend to.

If a user is assigned an administrative role that does not include administrative capabilities however, they might not notice them in the interface. It doesn’t necessarily mean the core API isn’t able to be called by it directly. It is important to test the API rather than just looking at what appears.

Modern web-based applications have greater attack surface

Applications today incorporate JavaScript front-ends APIs, cloud services and APIs. They also include integrations from third-party providers. There are weaknesses in any component as well being the trust relationship that exists between the two.

A thorough penetration test of web applications is conducted to determine the connection. The testers may look at the way tokens and authorization are handled, whether sensitive servers enforce the same rules, how data is moved between servers by users and even if a vulnerability that seems to be of low risk could be coupled with another vulnerability, resulting in a severe attack.

Siege Cyber is specialized in the testing of applications in this manner. It works with modern frameworks and APIs as well as cloud-hosted applications and intricate architectures.

The report will aid developers fix the issue

Finding vulnerabilities is just half of the task. When security experts are able to replicate an issue, comprehend the danger and can confidently fix it, security testing can be most valuable.

Siege Cyber reports include evidence replication steps Risk ratings, impact analysis, and remediation guidelines. Technical teams receive the details needed to resolve the issue while business executives receive an executive-level description of the exposure. Instead of waiting for the report’s final version, critical findings can be escalated to business stakeholders at the time of the meeting.

The process of retesting the system following remediation offers another layer of assurance because it confirms that the original problem has been fixed without having to design a new system.

For those who want independent validation, compliance evidence, or greater confidence before an important release, penetration testing provides something policies and automated tools cannot offer: a chance to discover the ways in which skilled hackers could actually attack the system. The importance of the test is to find the right answer prior the actual attacker.
