Security Auditing Process Roadmap

1

Engagement and Scope Definition

The firm initiates the process by engaging with the client to understand their needs.

A clear scope for the audit is defined, including specific applications, systems, or smart contracts to be audited.

2

Documentation and Preparation

The client provides relevant documentation, access, and resources necessary for the audit.

The auditing team prepares tools, schedules, and protocols based on the scope.

3

Security Review

A comprehensive security review is conducted. This includes automated scanning and manual testing techniques to identify vulnerabilities.

For web and mobile apps, this step includes both static and dynamic analysis.

For smart contracts, this step involves code review and testing against known vulnerabilities.

4

Vulnerability Assessment

Identified vulnerabilities are assessed for their severity, impact, and exploitability.

A report is prepared detailing each vulnerability with recommendations for mitigation.

5

Client Review and Mitigation

The client reviews the vulnerability assessment report.

The client or their developers implement the recommended fixes or mitigations.

6

Verification of Fixes

Once fixes are applied, the auditing team re-tests the specific areas to verify that vulnerabilities are properly addressed.

Additional rounds of review and fixing may occur until all critical issues are resolved.

7

Final Reporting

A final report is prepared, including an executive summary, details of the testing process, vulnerabilities found and fixed, and recommendations for future security practices.

The report is presented to the client, along with any final recommendations.

8

Post-Audit Support

The firm offers post-audit support to address any questions or assist with implementing security practices.

Expertise

Networks

We advise clients in the EVM, Move (Sui, Aptos), Cosmos, Avalanche, Solana, Filecoin, Sei, Conflux and TON ecosystems, as well as wallets, cross-chain infrastructure, L1s and L2s.
