As blockchain projects continue to scale globally, security breaches remain a critical issue. Due to the open-sourced, decentralized nature of blockchain, hackers can easily interact with companies from anywhere in the world.
At the smart contract level, formal verification is the only level of rigor that can objectively show immunity against some of the most critical and frequent vulnerabilities. The formal verification process mathematically proves, or disproves, that the intended code functions the way it’s supposed to. Rather than depending on manual review, mathematical systems can calculate against near-infinite scenarios.
However, security is an ongoing process, and running a one-off smart contract audit simply isn't enough to protect assets stored. For example, security on a cryptocurrency exchange is fundamental for safe transactions and the protection of traders' funds. Any exploitation, economic or not, can cause detrimental losses.
To protect the interests of all stakeholders involved, security can be examined on a more detailed level. Penetration tests, also known as pen tests, simulate a cyberattack and focus on identifying vulnerabilities in a targeted environment. Insights gained from a penetration testing service can help blockchain projects identify and protect against potential vulnerabilities, including unethical hacks.
Types of Penetration Testing Services
There are many different methods of pen testing. While some may be more complex than others, your security expert will decide what is best suited for the project.
External Testing
An external penetration test involves targeting assets that are visible on the internet, including web applications, company websites, email servers, and domain name servers (DNS). This information usually contains valuable data sought out by hackers.
Internal Testing
Internal testing is conducted by simulating an attack from within a firewall. In this type of testing, the pen tester assumes the role of an authorized user with standard access privileges. The goal is to determine the extent of damage an authorized user can inflict on the network.
Blind Testing
During blind testing, the security expert assumes the identity of a real attacker who uses only publicly available information about the company, such as its name and location. A potential attacker must conduct reconnaissance before launching an attack due to the limited availability of information. This type of testing is time-consuming and typically expensive.
Double-Blind Testing
Similar to blind testing, the supposed attacker only has access to publicly available information. During a double-blind test, the security staff is not notified when the attack will happen. This keeps you on high alert with a watchful eye for upcoming security breaches.
Targeted Testing
Targeted testing is conducted in collaboration with your company and a penetration testing team. During a targeted test, everyone can see the test being carried out and analyze the results. In the tech world, this approach is commonly referred to as the "light turned on" approach.
What’s The Point?
A penetration test can help build a more robust security posture and identify potential vulnerabilities that may have been overlooked. While security is the heart and soul for many blockchain companies, it’s crucial to take any vulnerability seriously.
