Corporations have invested significant resources over the years to bolster their IT asset security. However, hackers have continuously evolved their techniques, posing a formidable challenge to cybersecurity. This has led to an ongoing race between the two, with threat actors quickly adapting to counter any defense.
For example, Multi Factor Authentication (MFA) was initially praised as a robust defense against weak passwords. However, malicious actors have devised ways to bypass it using social engineering to steal authentication codes.
It reflects the increasing sophistication and adaptability of cyber threats. That’s where CREST penetration testing comes into play. It helps organizations to fill the security gaps before they become breaches.
This article digs deeper to explore CREST penetration testing, its advantages, and how it’s conducted.
What is Penetration Testing?
A penetration test, or pen testing, is a method of conducting simulated cyber attacks to identify security vulnerabilities and mitigate security risks. This involves testing applications, IT networks, APIs, servers, and computer systems to uncover hidden vulnerabilities, such as code injection, weak passwords, misconfigurations in firewalls, insecure network protocols, and application layer vulnerabilities.
These insights help identify vulnerabilities and weaknesses to mitigate threats, strengthening overall security, processes, and policies.
Types of Penetration Testing
There are several types of penetration tests; each serves its own distinct objective. They broadly fall into the following categories:
Network Penetration Testing
As the name suggests, network penetration tests aim to identify weaknesses in the IT network infrastructure, be it on-premise or in a cloud environment. Network penetration tests are ideal for cloud-based companies.
Mobile Penetration Testing
Popularly known as mobile pen testing, it targets mobile applications to identify security weaknesses. For companies developing gaming applications, payments, and shopping carts, mobile penetration testing is an ideal solution. It allows them to test security loopholes in the application before releasing them in the market for public consumption.
API Penetration Testing
Nowadays, businesses rely on multiple APIs to deliver services, thereby expanding the attack surface. API penetration testing aids in identifying potential vulnerabilities across various types of APIs, including REST, SOAP, and GraphQL. Companies that use applications to deliver services should regularly conduct API penetration testing to safeguard their applications from potential vulnerability exposures.
Cloud Penetration Testing
Also known as cloud pen testing, cloud penetration testing involves conducting cyberattacks on an organization’s cloud-based applications and infrastructure, including data storage and networks used for data transfer. It is particularly effective for companies that provide cloud services, such as AWS, Google Cloud Platform, Azure, and cloud security services.
Social Engineering Penetration Testing
Social engineering penetration testing involves creating scenarios in which bad actors trick employees into providing access to sensitive information. This type of testing is specifically useful for organizations seeking to assess their employees’ security awareness and readiness.
Automated Penetration Testing
Also known as phishing assessments, this method involves automated tools for simulating attacks and identifying hidden vulnerabilities in systems. Automated scanning is beneficial as it can rapidly detect a large number of vulnerabilities in systems.
Understanding CREST Penetration Testing
CREST refers to ‘the Council of Registered Ethical Security Testers,’ a not-for-profit accreditation body that sets cybersecurity penetration testing standards. It ensures that the quality of penetration testing services meets the highest legal and ethical standards.
This certification and methodology are internationally recognized and utilized by reputable companies striving for excellence in penetration testing.
CREST certification validates the quality of a company’s pen testing service. Therefore, it makes sense to engage with CREST-certified companies.
Why CREST Penetration Testing Matters
Collaborating with CREST-certified testers instills confidence in businesses regarding the quality of penetration tests conducted by skilled security professionals. These professionals adhere to rigorous standards and best practices while appropriately managing risks. This confidence and trust stem from the meticulous processes CREST follows in awarding certification.
Attaining CREST accreditation entails meeting stringent criteria that encompass operating procedures, standards, and best practices for penetration testing. Companies must maintain meticulous documentation, including insurance certificates and sample client contracts to achieve accreditation. Additionally, they need to obtain necessary compliance certificates, such as ISO 27001, ISO 9001, and SOC2.

The Process of CREST Penetration Testing
Below is a comprehensive, step-by-step guide outlining the process of CREST penetration testing process for vulnerability assessment:
1. Scoping
During the scoping phase, the vulnerability assessment provider compiles a list of IT assets slated for auditing in the penetration testing process. Additionally, the penetration testing company establishes assessment rules and endeavors to understand clients’ requirements.
Thorough scoping enables penetration testers to grasp the context of the applications under test. It entails comprehensive documentation of parameters and vulnerabilities, reducing the likelihood of unexpected costs or disruptions during testing. Scoping serves several purposes:
- Identifying the most critical data and business concerns to address during the test.
- Delimiting the security boundary for each penetration test.
- Defining the scope based on specific business risks, such as network security.
- Ensuring that testing aligns with the organization’s budget and security needs.
- Scanning
In the scanning phase, CREST-certified pen testers thoroughly scan every audited asset identified in the first stage. This includes a thorough examination of security controls, configurations, and compliances to ensure all potential security threats are identified and addressed.
3. Evaluation
Now, in the third stage, the vulnerabilities discovered in the scanning phase are categorized based on the severity level of the threats. This is achieved by assigning a score between 1 and 10, known as the Common Vulnerability Scoring System (CVSS) score.
- A CVSS score between 8-10 is considered serious, requiring critical and urgent attention.
- Scores ranging between 5-7 indicate a medium-level vulnerability.
- The score between 1- 4 indicates low-level vulnerabilities.
4. Reporting
Post-evaluation, the penetration testing team prepares a detailed report based on their finding. This may include the following:
- Detailed findings of vulnerabilities discovered
- A list of pieces of evidence supporting the successful exploitation of vulnerabilities
- Detailed remediation measures to address weaknesses
- An executive summary containing key findings and recommendations for senior management and other stakeholders
5. Remediation
The report comprises remediation measures for the threats identified during the scanning process. Vulnerabilities having a high CVSS score need to be patched urgently.
