The primary reason for periodic penetration testing of Internet-facing applications is to identify

vulnerabilities in the system, because this will help to improve the security and resilience of the

applications and the data they process. A penetration test is a simulated cyberattack that aims to

exploit the weaknesses and gaps in the security of an application or a system. A penetration test can

reveal the vulnerabilities that may not be detected by other methods, such as automated scanning

or code review. A penetration test can also measure the impact and severity of the vulnerabilities, as

well as the effectiveness of the existing controls and defenses. A penetration test can also provide

recommendations and solutions to remediate the vulnerabilities and prevent future attacks.

Internet-facing applications are programs and services that are accessible from the internet, such as

web applications, APIs, cloud services, or VPN gateways. Internet-facing applications are exposed to

a variety of cyber threats, such as denial-of-service attacks, SQL injection attacks, cross-site scripting

attacks, or credential stuffing attacks. These threats can compromise the confidentiality, integrity,

and availability of the applications and the data they handle. Therefore, periodic penetration testing

of Internet-facing applications is essential to identify vulnerabilities in the system and to protect the

applications and the data from cyberattacks. Reference = Web Application Penetration Testing: A
