What exactly are smart contracts?
Smart contracts in general &nbsp;are computer &nbsp;&nbsp;protocols that are stored in public databases that digitally simplify the implementation of an agreement. They are a more efficient, cost-effective, and secure method of executing and administering contracts. Some concerns with smart contracts that need to be addressed include the technical complexity of making updates and the inability to manage complicated transactions. Smart contracts on blockchain are basically programs that run when certain criteria are met and are maintained on a blockchain. They are generally used to automate the execution of an agreement so &nbsp;all parties can be instantly assured of its completion without the need for intermediaries or wasted time.
Smart contracts remove the need for third-party intermediaries such as lawyers, allowing for trustless processes, time efficiency, cost-effectiveness, and transparency. While blockchain can protect smart contract applications from traditional cybersecurity attacks, cyberattacks continue to evolve in the creation of additional threats and attack vectors that affect blockchain in the same way they affect other web and application-based systems. Effective blockchain testing aids organizations in developing and deploying the technology with connected infrastructure in a secure manner.
However, the experts discovered during their research that Blockchain technology has security issues such as irreversible transactions, unsatisfactory access, and non-competent strategies. These types of attack vectors aren't found on portals or other applications. This research presents a penetration testing framework for smart contracts and applications decentralized blockchain results of the proposed framework for penetration testing with automated penetration test scanners. white hat penetration testers who use tactics and tools to access or exploit computer systems, networks, websites and applications.
But, more broadly, what is penetration testing?
Penetration testing, also known as, security penetration testing, and security testing, is a type of ethical hacking. The primary goal of pen testing is to identify exploitable issues so that effective security controls can be implemented, security professionals can also use penetration testing techniques, along with specialised testing tools, to test the robustness of an organization's security policies, regulatory compliance, employee security awareness, and the organization's ability to identify and respond to security issues and incidents such as unauthorised access.
Ethical hacking tactics, like a simulated cyberattack, help protection professionals in comparing the performance of statistics security features inside their businesses. The pen check seeks to breach an organization's cyber defences via way of means of seeking out exploitable vulnerabilities in networks, online applications, and personal protection. The purpose is to become aware of machine flaws earlier than attackers do.
In the case of networks, the overarching aim is to improve security posture by shutting unused ports, debugging services, adjusting firewall rules, and closing all security gaps.
Pen testing is used to find, evaluate, and report on common online application vulnerabilities such as buffer overflow, SQL injection, and cross-site scripting, to mention a few.
<h2>Are there any techniques for pen testing?</h2>
Yes , &nbsp;Pen tests are used to determine whether or not an organization's security procedures are truly effective. Pen testing is often used to identify and patch vulnerabilities before a hacker does. The following are the options based on the frequency and type of penetration testing you intend to perform:
● External testing entails assaults on the organization's network perimeter undertaken from outside the organization's systems, such as the Extranet and Internet.
● Internal testing is performed from within the organization's environment, this test seeks to determine what may happen if the network perimeter were successfully breached or what an authorised user might do to get access to certain information resources within the organization's network.
● In a blind tasting, the tester attempts to mimic the activities of a genuine hacker. The testing team has little or no knowledge of the business and must rely on publicly accessible information (such as the corporate website, domain name registration, and so on) to acquire information about the target and execute penetration tests.
● Double-blind testing is some human beings within the organization are made privy to the checking out on this activity. Double-blind checking out permits an organization's protection tracking and incident identity processes
● Targeted testing is sometimes known as the lights-on technique. It involves both IT and penetration testing, teams. Targeted tests take less time and effort than blind tests, but they don't always give as thorough a picture of an organization's security vulnerabilities and response capabilities as other testing methodologies.
Do we still require penetration or pen testing if the smart contract is bug-free?
Yes, is the answer to this question, even if your smart contract is bug-free and safe, hackers can always find a method to attack potential security flaws and vulnerabilities. They can corrupt a smart contract or an entire blockchain network to steal hundreds of millions of dollars in cryptocurrencies. A smart contract's periodic penetration testing and security audit is the solution to this problem. Security audits and pentesting assist you in identifying possible vulnerabilities in your system and providing you with time to address these flaws before a hac.
What are some procedures for performing a smart contract security audit and pentesting?
Well, procedures for performing a smart contract security audit and pentesting are quite easy, as shown below.
● Conduct a static analysis of your code to find inconsistencies in style and susceptible code.
● Use reputable tools to do security research on your smart contracts, such as Mythril, MythX, Echidna, Oyente, Manticore, and ERC20 Verifier.
● Check for all of the vulnerabilities listed in the SWC Registry.
● During testing, set up a bug reward programme. Make use of a testnet such as Rinkeby.io or Kovan.
● If your business has experienced security staff, conduct penetration testing in-house.
● Create a full report on the vulnerabilities found in your system, as well as advice on how to repair them.
● If your internal security staff is unable of completing a security audit or pentesting for your smart contract, then hire a third-party security firm.
<h2>Conclusion</h2>
As a result, Penetration testing of smart contracts is very important because it discovers technical and functional flaws and assesses their severity (ease of use and impact on information systems) to create a prioritised set of recommendations for addressing discovered flaws. Security audits and pentesting assist you in identifying possible vulnerabilities in your system and provides you with time to address these flaws before a hacker(s) attempts to exploit them and breach your platform.
