The basics

What is Cloud Security Testing?

Our full cloud security testing service is both ethical hacking from the Internet against your cloud exposure as well as a white box authenticated audit against your cloud services, that will review your platforms against both accepted best practices and widely respected benchmarks.

The goal of cloud security testing is to ensure external attackers cannot exploit your cloud platforms and gain access to sensitive data held within. Whilst also ensuring that in the worst-case scenario if an attacker has managed to gain access to your cloud infrastructure, configuration provides difficulty in obtaining, extracted data as well as early detection and monitoring of the attack.

Testing Benefits

What are the benefits of a Cloud Security Testing?

As part of our security testing service, our experts essentially replicate what real-life hackers do, but in a legal framework. In exploiting vulnerabilities through a simulated attack, you can identify weaknesses in your external IaaS, PaaS and FaaS cloud exposure and therefore take action. Our white box audit will also allow us to identify any key misconfigurations on your platforms.

From these activities, we create reports identifying issues and details of how to fix them. Once you know where your weaknesses are, you can work to resolve the issues and protect your business from real hackers intending to cause harm and steal data.

Getting Started

What will we find in a Cloud Security Test?

The purpose of a cloud security test is to identify issues so that you can fix them before cyber criminals take advantage of them. To complete this, example activities that would be conducted are as follows;

  • Identify any DNS configuration issues that may lead to exploitation such as Subdomain takeovers.
  • Determine whether any sensitive data in relation to your cloud setup is in the public domain.
  • Review the exposure of services on your identified cloud endpoints. Ensuring that there are no excessively exposed services increasing your attack service.
  • Review access to your Metadata API (crown-jewels) from the public that if compromised could lead to full compromise.
  • Review the setup, configuration, and permissions of storage buckets in use. Ensuring that it is not possible to gain unauthorised access to data.
  • Determine any leakage of access keys such as Secret Keys , Storage Account Keys
  • Ensure that your cloud platforms have been locked down using security best practices.

The knowledge of your network's vulnerabilities puts you in a great place to develop your security measures and better protect yourself against cyber criminals.

CREST Registered - CREST Certified

Are you CREST Certified?

OnSecurity is a CREST (Council of Registered Ethical Security Testers) approved vendor. This means that all our test methodologies, processes, policies and procedures have been externally vetted by CREST to ensure we are operating to the highest standards possible in the pentesting industry.

On top of this the majority of our testers are CREST certified, meaning they have been through a CREST assault course (or CREST-recognised equivalent) to ensure they have the requisite skills needed to find and exploit vulnerabilities in a safe and controlled manner.

This external validation means you can be confident your pentests are being carried out to the highest standard, by vetted and tested consultants, who use a best-in-class manual-first approach to testing.
