The internet is used nowadays for everything from banking shopping, banking, and even business. However, the more time we spend on the internet, the more vulnerable to cyber-attacks. Hackers constantly look out for weaknesses to gain access to data or even damage systems. So, businesses need pen testing, or penetration testing. It helps identify and fix security weaknesses before hackers attack them.
What Is Pen Testing?
The pen test is an type of test that Pen testing involves cybersecurity experts acting like hackers. They try to hack into systems like websites, sites, or applications in an effort to find for security weaknesses. The idea is to reveal how hackers could hack the system and the kind of damage they can cause.
Pen testing professionals are known as ethical hackers. They follow the regulations and guidelines, and don’t cause any damage to the environment. Instead, they assist businesses identify and correct vulnerabilities.
- Pen testing is able test a lot of the following:
- Web applications and websites
- Mobile apps
- Networks and Wi-Fi
- Cloud-based infrastructure
- Internet-connected devices (like cameras or smart TVs)
- APIs (which are used to connect software)
Why Do We Need Pen Testing?
An organization may be protected by firewalls or antivirus software however, they may have vulnerabilities. They could be caused by insecure passwords, outdated software or insufficient configurations. Pen testing is a way to identify the issues ahead of time.
These are just a few reasons that pen testing is required:
Find Real Security Threats
Pen testers use real attack methods. They can spot issues which software scanners or tools can’t.
Fix the Most Important Problems First
Pen testers allow businesses to identify the issues that are most critical. They can then address the issues first.
Test If Security Is Working
Pen testing tests whether the firewalls as well as login system effectively protecting hackers.
Follow the Rules
The majority of industries (like healthcare or finance) have security rules. Pen testing is a way for companies to meet these requirements.
Protect the Company’s Reputation
A security vulnerability can damage a company’s reputation, and even cost the company money. Pen testing lowers the chance of it occurring.
Types of Pen Testing
There are three major kinds of pen testing:
Black Box Testing
The tester doesn’t have any knowledge of the system. It’s like an intruder trying to break into.
White Box Testing
The test subject is knowledgeable about this system. This includes codes, passwords, and configuration. This provides the most complete explanation of the possible issues.
Gray Box Testing
The test subject is aware of some facts However, they are not 100. This is in between white and black box testing and is extremely typical.
How Does Pen Testing Work?
Pen testing usually comprises the following steps:
Plan the Test
The company and the tester decide on what tests to conduct and in what manner. The tester conducts some research about the system.
Scan for Problems
- The tester utilizes software to look the internet for ports that are open, service and weaknesses.
- The tester employs real hacking techniques to determine how they can hack into the system.
Try to Break In
Check What Access They Got
If the tester is able to get into their system, they can determine how far they are able to get. Can they take information? Modify settings?
Write a Report
The test subject writes an account of what they have learned and the best way to correct it.
Fix the Problems
The company will fix the issue and the tester tests again to determine whether the patch worked.
Tools Testers Use
Pen testers make use of tools that are free or paid to assist them. A few of the most well-known include:
- Nmap Detects available ports as well as devices connected to networks
- Burp Suite Tests web websites and web-based applications
- Metasploit – Runs common attacks safely
- Wireshark tracks network traffic
- John the Ripper Cracks passwords
- Nikto Nikto Scans websites for servers that have been identified to cause issues
Be Ethical and Safe
Pen testing is legal only in the event that the company has given permission. Testing personnel must adhere to the guidelines and not harm the system. Professionally trained and experienced ethical hackers are the type of people companies should hire. Check if they are certified such as CEH (Certified Ethical Hacker) or OSCP (Offensive Security Certified Professional).
Conclusion
Pen testing isn’t something that you can only do only once. As systems evolve and develop the threat landscape is constantly evolving. Continuous pen testing helps businesses stay in front of criminals.
Pen testing is like a fire drill. It reveals the potential for mistakes and what you can do to avoid it. In this day and age, which cyberattacks occur frequently pen testing is one of the most intelligent things companies can do to ensure its security.
