Penetration testing, commonly known as pen testing, is a cornerstone in cybersecurity. It is a deliberate, comprehensive assessment where cybersecurity experts, mimicking the tactics of potential attackers, seek out vulnerabilities in an organization’s digital infrastructure. 

The essence of pen testing lies in its proactive approach—instead of waiting for a breach to occur, organizations use pen testing to preemptively discover and address security weaknesses.

Pentesting can be broadly categorized into several types, each with its unique focus and methodologies:

  • External Penetration Testing: Targets the assets of an organization that is visible on the internet, such as web applications, websites, and external network servers, essentially anything that an outsider could access.
  • Internal Penetration Testing: Simulates an attack by a malicious insider or an attacker who has gained access to the internal network. This type of testing uncovers vulnerabilities that could be exploited from within.
  • Web Application Penetration Testing: Focuses specifically on identifying security issues in web applications. This includes testing for common vulnerabilities such as SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF).
  • Social Engineering: Involves techniques that manipulate individuals into performing actions or divulging confidential information. This type of testing evaluates the human element of security.

The pen testing process typically unfolds in stages:

  1. Planning: Establishing the scope and goals of a penetration test, including the systems to be examined and the testing methods to be used.
  2. Discovery: Gathering information to understand how the target application or system operates identifying potential entry points and vulnerabilities.
  3. Attack: Attempting to exploit vulnerabilities to determine whether unauthorized access or other malicious activities can be achieved.
  4. Reporting: Providing detailed findings of the vulnerabilities discovered, evidence of the exploit, and recommendations for remediation to improve security.
