1. Overview

Smart contracts represent a significant departure from traditional centralized information systems, as they rely on the trustworthiness of code rather than the integrity of corporate actors. On Web3, billions of dollars can be managed solely by lines of code. This gives rise to Cryptosecurity —a sector involving technologies that help secure digital wallets and cryptocurrency transactions. As Web3 is rapidly growing, so does security providers need to mitigate and moderate the looming risks in this highly decentralized space.  

This article will delve into CertiK. From that, we can understand its paramount role in empowering and helping projects navigate the myriad challenges of Web3 Security.

2. CertiK’s Auditing Methodology

When it comes to security there should be no compromise. The CertiK team ensures this through a combination of leading technologies and a rigorous auditing process in their services combining both manual review and automated tools.

2.1 Process Overview

CertiK’s audit process commences with the acquisition of the source code and the establishment of a tailored environment. Before delving into the utilization of in-house tools and manual examination to uncover any security vulnerabilities and design defects, the project documentation is examined by auditors who also perform threat modeling. Upon the completion of the audit, a detailed report containing the findings and recommendations is presented to the client.

2.2 Key Components Review

Environment Setup: Certik’s support extends to over ten major blockchain ecosystems and smart contract programming languages. They utilize pre-configured virtual machine environments to mitigate complications in the set-up process caused by some other languages. Any code added to these environments undergoes thorough examination for successful compilation and deployment capabilities. The environment equips auditors with the ability to execute code and carry out tests, enabling them to gain a practical comprehension of the project.

Architecture Review: Determining a project's architecture is crucial for effective threat modeling and understanding security-critical components. While it is ideal for clients to provide detailed documentation describing the architecture, there may be instances where auditors need to perform architecture extraction due to the absence of these artifacts. This involves examining component interactions, external inputs, code compliance, and concurrency, among others. Visualization tools can aid the process, but poorly organized or unconventional projects may necessitate manual analysis. It's also essential to identify if a project is an original design or a fork, as forks may inherit vulnerabilities from the original project.

Threat Modeling: A Threat Model represents a system's critical assets, resources, security requirements, vulnerabilities, and threats. It's established during an architecture review by posing and answering questions based on the system's architecture. The Threat Modeling process produces a security checklist for the security audit and ensures a thorough evaluation of the system's security posture.

Static Analysis & Formal Verification: CertiK’s in-house tools draw on their extensive experience and database of over 60,000 findings from 3,500+ audits and incidents. By testing code statically at the source code and bytecode levels, they can identify insecure code patterns and generate diagrams to enhance smart contract visibility. The tools' efficacy improves with each audited project, and CertiK also provides formal verification to ensure program specifications are met. Formal verification mathematically proves a program's intended function by expressing its properties as formulas and using automated tools to check its veracity. Findings typically include logic issues, reentrancy risks, and lack of access controls. Manual verification by auditors removes false positives and enhances result clarity.

Reporting & Remediation: CertiK’s audit reports are comprehensive and provide a thorough analysis of a project's security posture, beginning with an overview of the project's type, ecosystem, and scope. The reports include an appendix that defines our security ratings and terminology, as well as detailed descriptions of our methodology and auditing approach. They also provide specific testing information, including formal verification processes and their results.

The findings include detailed explanations of identified issues, with metadata such as category, severity, file location, and alleviation status. Each finding is divided into four sections: Description, Scenario, Proof of Concept, and Recommendation. These sections provide targeted and actionable information to improve readers' understanding of the findings.

The remediation phase is an ongoing dialogue between the client and CertiK’s auditors to improve the project's security. The client receives the initial security assessment and provides updated source code or comments. Then auditor updates the findings accordingly and publishes an updated report. This process repeats until the client is satisfied with the final security assessment. Their reports are published to clients and publicly available on the Security Leaderboard, allowing community members to view how projects improve their security ratings using CertiK audits and security services.
