How to Perform Blockchain Penetration Testing?

Blockchain technology is popular in various fields. Not surprisingly, hackers are becoming more active as the popularity of cryptocurrencies grows. Cybercriminals are not uncommon to exploit security vulnerabilities in blockchain applications that arise from improper application implementation and maintenance. Blockchain technology is our future. And to fully take care of security, various tests and blockchain integrity assessments should be held. In the modern world, ensuring security requires blockchain penetration testing. We will tell you about the blockchain network, and blockchain security, explain various blockchain testing requirements, etc. So, how to perform blockchain penetration testing?

What is Blockchain Security?

Blockchain security is a comprehensive risk management system for the blockchain network that applies provisioning services, cybersecurity structures, and best practices to mitigate risks from hacker attacks and fraud.

Blockchain penetration testing

A hacker can potentially use vulnerabilities, code errors, and security loopholes to break into a system, which will lead to serious losses. In the penetration test, a hacking situation is simulated. In this case, the testers themselves act as hackers. Performing blockchain penetration testing allows you to detect vulnerabilities in time. The shortest tests can only take a few minutes, while the longest can take months. Therefore, blockchain penetration testing is an essential tool for security assessment.

The process of Blockchain penetration testing: 5 Steps 

Blockchain penetration testing involves core testing services such as API testing, functional testing, security testing, performance testing, integrating testing, etc. In addition, penetration testing is designed to identify possible weaknesses in the system.

Discovery

First, the tester is required to detect potential vulnerabilities in the system. to do this, one should have a good understanding of blockchain technology and blockchain architecture. Namely, the extent to which the blockchain can maintain confidentiality, integrity, and availability during the delivery, execution, and storage of confidential data. The implementation of the blockchain must comply with all legal requirements of governance. You should also study the technological features of the Blockchain application. All this will help to take care of security as efficiently as possible.

Evaluation

At this stage, information is evaluated and analyzed. Then, the tester determines which loophole or vulnerability can compromise the blockchain application. At this stage, there are:

  • Network Penetration Testing includes dynamic and static testing of applications, such as application logic, GUI, and databases.
  • Blockchain integrity testing allows you to analyze attack vectors.

Functional Testing

The goal of Functional Testing is to make sure that all services in a blockchain application are working properly. The tester takes into account the following components:

  • Adding blocks

This process should be controlled.

  • Transfer of information

Blockchain’s peer-to-peer architecture makes it easy for testers to decrypt and encrypt data.

  • Block and chain size

The block, which is 1 MB, contains information about the transaction. There is no limit on the chain size because it continues to increase over time. Circuit performance should be checked regularly.

  • Performance Testing

The goal is to identify potential bottlenecks and verify that the application is ready for production.

  • API testing

it is performed to test the interoperability of the Blockchain application ecosystem.

  • Security Testing

The goal is to ensure the blockchain application is protected from viruses and malware.

  • Integration testing

The need for such testing appears due to the deployment of the blockchain on parallel platforms.

Reporting

The test report is an important milestone. This report should describe the vulnerabilities found to make it easy for security specialists to work on improving protection mechanisms.

Remediation & Certification

It is the last critical step in penetration testing, which includes fixing the vulnerabilities reported by the tester. Rescan is performed.

Conclusion

The rapid development of blockchain technologies has led to increased activity of hackers. Therefore, to secure the application blockchain, pay attention to the penetration test. It is an important stage that allows you to detect vulnerabilities in the application in time and take all measures to ensure security.

FAQ

What are the three types of penetration testing?

To effectively identify vulnerabilities in web applications, three types of PEN testing are carried out: white box testing, black box testing, and gray box testing.

How does blockchain ensure security?

Blockchain technology gives you the ability to create structured and encrypted data structures. Blockchain is based on cryptography methods, consensus mechanisms, and other algorithms to ensure reliable security.

How is penetration testing performed?

Such a test uses web application attack strategies, including SQL injection, cross-site scripting, and workarounds to identify the targeted vulnerability. Testing allows you to exploit a vulnerable system by stealing data, escalating privileges, intercepting traffic, etc., to see the harm it can cause.
