What is a CREST Certified Pen Test?

Penetration testing is an authorized attack by ethical hackers to discover, quantify, and supply mitigation strategies for identified security gaps and vulnerabilities.

A CREST Certified Pen Test is an assessment conducted by a CREST-accredited provider firm or CREST Registered Penetration Tester. CREST accreditation verifies that a company perform and documents penetration testing following the highest ethical, legal, and technical standards.

Penetration Testing Types

Internal Penetration Testing

Internal penetration tests run from enterprise-within, over its WIFI networks or Local Area Network. The tests will help identify whether it is possible to acquire access to privileged enterprise details from systems and devices inside the corporate firewalls.

External Penetration Testing

The type of testing assesses enterprise infrastructure from outside of the perimeter firewall on the Internet. The exercise will help evaluate the security controls configured on the firewalls, access routers, Intrusion Detection Systems (IDS) and Web Application Firewalls (WAFs) that shield the periphery.

Segmentation Testing

A segmentation test is a series of penetration trials used to check and confirm that less-secure networks limit communication with high-secure networks. Here, we test the controls to ensure proper segmentation without security holes and communication between these networks is confined.

Penetration Testing Strategies

Black Box Testing

Black box penetration tests reflect a simulation of how an attacker with zero information, such as an internet malicious user, organized crime, or a nation-state-sponsored attacker, could introduce risk to the environment. Any publicly available target data is a valuable feed for the penetration tester.

White Box Testing

White box penetration tests or complete knowledge testing mark an approach of testing where the pen testers have detailed information about the applications and infrastructure. The process delivers a stronger assurance of the application and infrastructure logic.

Grey Box Testing

It is a blend of black-box and white-box testing techniques where the pen testers hold snippets of information to help with the testing procedures. It provides more testing coverage than black box tests and is the ideal cost-effective approach for customers having budget constraints.
