What is External Penetration Testing?

External penetration testing is a type of security assessment designed to identify and fix vulnerabilities within publicly accessible network infrastructures by replicating the same techniques used by hackers. External network infrastructures are among the most targeted components. This is why experts recommend to perform external assessments at least once a year or following any major changes to the infrastructure to stay on top of the latest cyber threats. Conducting an external pentest is also required by various standards, such as PCI-DSS, ISO27001, and SOC 2.

Why Test the Security of Your External Network?

Bots and hackers are continuously probing the public internet for vulnerable entry points, which makes your external networks the most important asset to protect in order to prevent incidents. An external penetration test will allow your organization to answer the following:

Are my systems up to date and properly configured?

Have I successfully secured every service exposed on the internet?

Is my confidential data properly secured or publicly accessible?

Could a ransomware infiltrate my network from the internet?

Does my firewall intercept common hacking attempts?

According to best practices, it’s highly recommended to perform external security assessments at least once a year or following any major changes to the infrastructure to stay on top of the latest cyber threats. Conducting an external penetration test on a yearly basis is also required by various standards, such as PCI-DSSISO27001, and SOC 2 to maintain compliance.

External penetration testing is important because it tests the security of a company’s public-facing assets. This is important because these assets are typically the most vulnerable to attack, and if they are breached, it can be very costly for the company. External penetration testing helps identify and fix any vulnerabilities in a company’s external network that can be exploited by hackers, allowing organizations to mitigate their most important risk of facing a damaging cyberattack.

Internal penetration testing is conducted within an organization’s network and focuses on internal assets, while external penetration testing assesses the security of an organization’s external-facing systems, such as the network on which their public website is hosted. External penetration testing is generally considered to be more effective in preventing cyberattacks because it provides a more realistic assessment of how attackers would view and attack your system. Additionally, external testers are less likely to have inside knowledge of your system that could be used to exploit vulnerabilities.

Internal penetration testing is generally conducted by organizations with a well-developed and mature cybersecurity strategy or with specific compliance requirements, such as the card-processing standard PCI-DSS, which requires a yearly internal test to be conducted.
