What Is Penetration Testing?

Penetration testing, also referred to as "pen testing", is a security test performed on computer systems, networks, or applications. The objective is to identify vulnerabilities beforehand rather than wait for them to be exploited by hackers. Businesses conduct pen testing to determine how their systems would respond to an actual cyberattack.

A security professional simulates a hacker and attempts to get into the system but in a lawful and controlled manner. This assists companies in repairing issues before they get out of hand.

Why Companies Require Pen Testing

Cyber attacks are on the rise more than ever before. If a hacker gains access to your system, they are able to steal information, take down services, or injure your reputation. Penetration testing is able to decrease this risk.

By testing regularly, businesses are always one step ahead. It's not mere box-ticking. It's ensuring that your data and the data of your customers remain secure. Numerous industries also have regulations that mandate regular security testing.

For instance, banks, medical facilities, and e-commerce stores tend to handle sensitive data. A breach in security in any of these sectors might result in fines, lawsuits, or loss of credibility.

Types of Penetration Testing

There are a few different ways to carry out a pen test, depending on what needs to be checked. Here are some of the most common types:

• Network Testing – checks for holes in your internal or external networks.

• Web Application Testing – focuses on websites, forms, and online services.

• Wireless Testing – looks for problems in Wi-Fi systems and connected devices.

• Social Engineering – attempts to determine if employees can be manipulated into providing access or confidential information.

• Physical Testing – attempts to find out if it is possible to physically make it into locked areas.

Both of these play various roles in your entire security configuration. Some organizations opt for one or two, whereas other organizations opt for a combination of all.

How the Testing Process Works

The steps begin with planning. The tester and the company come to an understanding about what shall be tested and what is being aimed for. After that's decided, the tester starts to collect information regarding the system. This is referred to as reconnaissance.

Then the tester attempts to identify vulnerabilities, like old software or open ports. They attempt to exploit the vulnerabilities, similar to how an attacker would. Each step is logged so that nothing is forgotten.

Following the test, the business receives a report. It contains what was tested, what was discovered, and the severity of the problems. Most reports also contain recommendations on how to resolve the issues.

Remaining Safe After the Test

Penetration testing is not a static job. Hackers are continually changing their methods and new threats emerge constantly. That's why most businesses conduct tests once or twice annually, or after any significant change to their systems.

It's also critical to address the issues promptly. A pen test will only be useful if the findings result in action. Keeping your software up to date, educating your employees, and regularly checking your systems can decrease future threats.
