What Is Penetration Testing and How Does It Work?

A penetration test, commonly referred to as a pen test, simulates a cyberattack on your computer system to look for vulnerabilities that could be exploited. Web application security typically includes the use of penetration testing in addition to a web application firewall (WAF).

In order to discover security vulnerabilities like unsanitized inputs that are vulnerable to code injection attacks, pen testing involves attempting to enter into any number of application systems (such as frontend/backend servers, APIs, etc.).

The penetration tester’s insights can be used to polish your WAF security procedures and address any vulnerabilities that were found.

Stages of Penetration Testing

Five steps can be used to break down the pen testing procedure.

Planning and Reconnaissance

First-stage activities include:

1. Defining a test’s scope and objectives, including the systems it will test and the testing techniques it will employ.
2. Gathering information (such as network and domain names, mail servers, etc.) to learn more about a target’s operations and any possible flaws.

Scanning

The next stage is to comprehend how various intrusion attempts will be handled by the target application. Generally, this is accomplished by:

1. Static Analysis: Analysing a program’s code to determine how it will function when it is executing. These tools enable the entire code to be scanned in a single pass.
2. Dynamic Analysis: Examining the code of an application while it is actively being used. As it offers a real-time perspective on an application’s performance, this method of scanning is more useful.

• Gaining Access
  This stage involves identifying a target’s vulnerabilities via web application assaults like cross-site scripting, SQL injection, and backdoors. In order to understand the damage these vulnerabilities could do, testers then attempt to exploit them, often by elevating their permissions, stealing data, intercepting traffic, etc.
• Maintaining Access
  The objective of this stage is to determine whether the vulnerability may be utilized to establish a persistent presence in the System. long enough for a bad actor to obtain in-depth access. In order to steal the most private data from an organization, advanced persistent threats, which may stay in a system for months at a time, are often imitated.
• Analysis
  A report outlining the penetration tester’s results is subsequently created.

1. Specific weaknesses that were taken advantage of.
2. Sensitive data that has been accessed.
3. The period of time the pen tester was able to keep hidden in the system.

Security staff members evaluate the data to assist in configuring an enterprise’s WAF settings and other application security solutions to fix vulnerabilities and protect against future threats.

Penetration Testing Methods

• External Testing
  External penetration testing targets a firm’s online assets, such as the web application itself, the company website, email servers, and domain name servers (DNS). The objective is to obtain access and collect useful data.
• Internal Testing
  A tester who has access to an application that is protected by a firewall can simulate an insider attack during an internal test. This isn’t always acting like a rogue employee. An employee whose login information was taken as a result of hacking is a common place to start.
• Blind Testing
  In a blind test, the only data available to the tester is the name of the target company. Security personnel can see how an actual application attack might proceed in real time due to this.
• Double-Blind Testing
  During a double-blind test, security professionals are unaware of the simulated attack before. They won’t have the opportunity to strengthen their defenses prior to a breach attempt, as in the real world.
• Targeted Testing
  In this case, security personnel and the tester cooperate and keep each other informed of their whereabouts. This practical training method helps a security team to receive quick feedback from the perspective of a hacker.

How Does a Penetration Test Work?

A penetration test may cover a variety of “broad strokes,” such as:

• Appointing a person or group to perform the test as “white hat” hacker(s) at a random time and day.
• Members of the vulnerability management team scan the IP addresses of various network assets to find those that are using services or operating systems that have known security vulnerabilities.
• A sequence of simulated attacks against the network utilizing various attack techniques is being conducted by the penetration testing team. Any vulnerabilities from the initial scan may be the focus of these attacks.
• Attempting to contain, prevent, and undertake an investigation into the attack as if it were real.

The pen test team must take care to conduct the test safely. Poor test execution could really harm the target systems, leading to network asset congestion or complete system failure.

Concluding Remarks

In order to test the system or application and determine whether the code is secure, testers must act to be actual hackers. If a security policy is properly executed, a penetration test will be effective. To increase the efficiency of penetration testing, the technique and policy should be considered.
