Mysten Labs Deputy Chief Information Security Officer Talks About Sui Blockchain Security

Recently, we had the privilege of having an in-depth conversation with Christian Thompson, the Deputy Chief Information Security Officer of Mysten Labs, discussing his insights on the interconnectivity of security practices, as well as his observations and evaluations of security practices for Sui developers.

Responsibilities of the Chief Information Security Officer

The Chief Information Security Officer (CISO) has a wide range of responsibilities and is crucial for protecting the security of the digital environment. The main tasks include:

1. Collect threat intelligence to understand the motivations and capabilities of potential attackers.
2. Establish a defense system to respond promptly to suspicious activities.
3. Covering multiple fields such as network security, data management, and risk assessment.
4. Protect internal team members and assess their risk levels.

The work of a CISO is like a puzzle game, where understanding the "players" and how they operate allows for more effective combination of various pieces to build a comprehensive security defense system.

Security Considerations of Sui Blockchain

For L1 blockchains like Sui, security strategies need to integrate multiple functions and services, focusing not only on weak points but also on protecting the interests of the entire ecosystem. The Sui Foundation is developing a product that extends advanced security measures to a broader ecosystem, allowing small companies to access security tools and services that are typically only available to large organizations.

Blockchain Security Tools and Services

The types of services and tools used by the security team include:

• Brand Defense
• Integrity Management
• Vulnerability Detection
• Fuzz Testing
• Regulatory Risk Assessment
• Governance and Compliance

These tools need to be customized according to the characteristics of different organizations. For example, companies closely related to coding may prioritize developing vulnerability detection capabilities, while decentralized finance companies may focus more on regulatory risks and compliance.

Maintain the Security of the Public Blockchain Ecosystem

In a decentralized and permissionless public chain environment, maintaining network security requires the following methods:

1. Build the necessary security tools
2. Promote community education
3. Strengthen Information Exchange

This three-pronged approach enables the community to understand and actively influence various security behaviors.

Communication Methods in the Sui Ecosystem

The Sui ecosystem communicates through multiple channels:

• Verification Node Summit
• Builder Houses event
• Platforms such as Discord and Telegram
• Security-related articles planned for release by the Sui Foundation

These channels promote interaction between validation nodes, node operators, and other stakeholders, creating a continuously evolving platform for knowledge exchange.

Security Advantages of Sui Move

The Move language is safer compared to other programming languages, and the security of Sui not only comes from the language itself but also from its construction method. The Sui development team includes many security experts, making the entire system more resilient and harder for attackers to exploit.

The Impact of Web3 Vulnerability Incidents on Sui

The vulnerability incidents in the Web3 space have provided valuable learning experiences for Sui. The Sui Foundation team has invested significant resources in researching these threats to optimize and strengthen its security strategies. These incidents have not only elicited sympathy but also provided opportunities for Sui to improve.

The Future Outlook of Web3 Security

With the arrival of the Web3 era, technologies such as artificial intelligence, machine learning, augmented reality, and virtual reality will bring about significant transformations. The security field will also see new developments, such as AI-assisted threat identification and even scenarios where AI counters AI. Sui is expected to be at the forefront of the application of these advanced technologies.
