Why do you need Cloud Penetration Testing Services?

An authorised cyber attack simulation exercise against cloud assets hosted on a cloud provider environment.

The main objective of cloud penetration testing or cloud pentesting is to identify and mitigate security risks in cloud computing. So that the cloud security posture, strengths and security weaknesses of cloud systems can be assessed. It is composed of external (Internet-facing) and internal cloud penetration test assessments.

Cloud security infrastructure is everyone’s business.

Gartner predicts that, through 2020, 95 percent of security failures in cloud environments will be the customer’s fault.

What can't be tested in the Cloud services?

Cloud technologies or cloud system that belongs to the cloud management such as underlying cloud infrastructure, cloud providers facilities, other partners or vendors cannot be tested in cloud penetration testing. For example, network stress test or DDoS simulation test, DNS Zone walking tests must be consulted with the cloud provider. Apart from major public cloud provider offerings, cloud models for a beginner can be fuzzy concepts, especially shared responsibility models. This simply means:

Cloud providers are responsible for security of the cloud

The tenant or organisation client is responsible for security in the cloud

The following diagram demonstrates the differences between shared responsibility models in the cloud. The following design principles are pillars to almost every cloud implementation.,

Vulnerabilities identified during cloud security testing

In order to easily understand the different cloud security risks and security posture, this section provides examples with each risk mentioned below. Security risk areas remain the same, the underlying attack vector may change based on the cloud model and/or cloud platform vendors.

For instance, Amazon buckets have a history of security misconfiguration linked to S3 bucket data leakage. Azure blob storage has been the target too and subjects to Identity-based attacks. Office 365 tenancy security configuration is not in line with good security practices.

cloud pentesting

When it comes to intellectual property theft, cloud pen testing can be a valuable service. By identifying vulnerabilities in the system, we can help organisations to better protect their data. Intellectual property theft often occurs when hackers gain access to sensitive information, such as trade secrets or customer data.

Our cloud pen-testing can help organisations identify compliance violations. By simulating an attack, we can determine how well data is protected and identify any potential weaknesses. In addition, our pen testing can also help to assess whether an organisation’s security policies are adequate.

Data breach vulnerability in cloud pentesting is becoming an increasingly important issue as more businesses rely on cloud-based services. There are a number of ways in which we find data breach vulnerability in cloud pentesting, but one of the most effective is to identify data sets that are potentially vulnerable to attack. While data breach vulnerability in cloud pentesting is a serious issue, it is important to remember that reputable cloud penetration test services can be used to effectively mitigate these risks.

Insider threats are one of the major concerns for many organisations. While most companies focus on protecting their data and applications from external attacks, insider threats can be just as damaging. After all, insiders already have access to sensitive information and systems, making it easier for them to wreak havoc. We find them during a cloud configuration review and let the oranisations know before attacks.

Credential attacks are a type of hacking where criminals try to gain access to your accounts by using your login information. These attacks can be very difficult to prevent, because they usually involve guessing or stealing passwords. However, they can be minimised by working on vulnerabilities found in cloud penetration testing.

In a cloud infrastructure review, Insecure APIs are found which may not follow the recommended security practices. This could lead to vulnerabilities in the system which could be exploited by a malicious individual. In order to mitigate this, we recommend that organisations follow the strategies put forward by our cloud penetration testers.

DDoS attacks are a type of security breach that can target any type of online service. DDoS attacks work by flooding the target with requests from multiple computers, overwhelming the server and preventing legitimate users from accessing the service. DDoS attacks can cause significant disruption and downtime for organisations, which is why it’s important to be aware of DDoS attack vulnerabilities by using our cloud testing services.

Benefits of Cloud Pentesting Services

How to pentest cloud computing environments?

Understanding the policies of cloud providers – Almost all public cloud providers (aws cloud, google or azure services) have cloud pen testing processes in place. This is often known as the customer support policy for penetration testing cloud. This policy defines explicitly what activities are permitted and prohibited under cloud penetration testing exercise in their environment.

It is similar to other policies such as network stress testing, DDoS simulation testing. Examples of these cloud penetration test rules of engagement (such as Microsoft, Amazon Web Services, Google or Oracle Cloud Security Testing) or permission policies are available on cloud provider portals.

Businesses looking to conduct testing cloud penetration testing (or security assessments) should have a cloud penetration test plan in place. This plan should include information related to applications, data access, network access, laws & regulations to comply with the cloud application security testing or databases and assessment approach (white box, grey box or black box). See our in-depth article for the basics of security reviews.

Constantly identifying vulnerabilities in cloud environments is very important. Cloud penetration testing ensures that no blind spots (such as vulnerabilities in the virtual machines facing the Internet) are present in your environment.

The right toolset (whether automated tools for vulnerability scanning or manual checks) is an important component of advisory services just like on-premises for cloud application security testing or a security audit. Both cloud and on-premises tools are available, and a thorough requirements analysis should be performed to finalise the correct approach.

This phase is relevant to the previous one based on the tools and resources used. Correct tooling and security resource usage are the two most important aspects of vulnerability identification and analysis.

Using in-house teams to perform cloud penetration testing may miss certain findings due to close familiarity with the cloud environment. Cloud testing with the right cloud service provider is not an option these days, it’s the surest way to prove that your cloud assets are securing the underlying data.

Risk remediation is an important element, that feeds back into the risk management programme of an organisation. All risk advice is provided in our deliverables after cloud pentesting services and cloud environment to help the security team analyse and devise remediation plans. It includes a description of risks in the context of the environment, followed by attack probability and impact.

If required, Cyphere provides additional remediation consultancy given the complexity around risk and specific skill-set required for risk remediation of cloud penetration testing findings.

Cloud Security Penetration Test Methodology

Our cloud security offerings are based on extensive methodology we have developed with years of experience working across different sectors. It’s very important that a cyber security consultancy follows an approach that delivers right returns on your investment. At a high level, our approach towards pen testing cloud services is as follows:

Step 1
Step 1

Identity and Access Management

This phase involves reviewing identity and access management related controls. Generally, these include checks on the use of higher privilege accounts, use of MFA, password policy, IAM policies, access keys and credentials usage policies.

Step 2
Step 2

Review Authentication Architectures

Authentication and authorisation problems are prevalent common cloud vulnerabilities. Most mobile apps implement user authentication.

Even though part of the authentication and state management logic is performed by the back end service, authentication is such an integral part of most mobile app architectures that understanding its common implementations is important.

Step 3
Step 3

Network Security

This area involves checks around network security controls such as ingress, egress rulesets, flow logging, traffic restrictions, and least access privileges.

Step 4
Step 4

Logging API Calls, Events

Every major cloud services provider offers web services that record API calls for tenant account. This information contains various parameters such as API source, calls details, requests/response elements.

This phase includes a review of API calls for an account, log file validation, encryption at rest, access checks if logs are restricted from public view and access logging, configuration management and monitoring options.

Step 5
Step 5


The monitoring phase is one of the critical tasks responsible for alerting relevant contacts during an incident. This involves reliance on the logging and related configuration parameters to ensure right metric filters are in place.

These reviews include checks for real-time monitoring configuration, alarms for any changes made to access control lists, security policy/groups, routing tables, and related parameters.
