Mysten Labs Security Officer Talks About Sui Blockchain Security Design and Practice

Recently, we interviewed a senior security officer from Mysten Labs to discuss his views on the interconnectivity of security practices and his observations and evaluations of security practices for Sui developers.

Responsibilities of the CISO

The responsibilities of a Chief Information Security Officer (CISO) are extensive and crucial for protecting the security of the digital environment. The main tasks include gathering threat intelligence and gaining insight into the motivations and capabilities of potential attackers. This helps in taking proactive measures to protect systems, much like a puzzle game, where understanding the players allows for more effective combination of pieces.

Security officials are also responsible for establishing real-time alert systems to respond quickly when suspicious activities are detected. Their responsibilities cover multiple areas including cybersecurity, data management, risk assessment, architecture design, compliance, governance, resilience, and reporting.

In addition, protecting internal team members is also one of the important responsibilities, especially when team members travel to high-risk areas.

Security Considerations of Sui Blockchain

Creating defense strategies for L1 blockchains like Sui requires the integration of various functions and services. The strategies not only focus on weak points but also need to consider the interests of the entire ecosystem, including the network and developers.

Given the high cost of security investments, the Sui Foundation is developing a product that will extend security measures to a broader ecosystem. This will enable small companies to access security tools and services that are usually only available to large organizations, allowing them to build applications in a safer environment and enhance the confidence of users and regulators.

Blockchain Security Tools and Services

The security team uses a variety of services and tools to build a robust security framework. The interactions, implementation order, and synergies between these tools are crucial.

The Sui network uses specific tools or relies on service providers to deploy these services. The Sui Foundation plans to package these components and provide them to businesses in need.

Priority of Security Toolkit

The design of the security toolkit is well thought out and can be customized according to the needs of different organizations. For example, companies closely related to coding may prioritize the development of vulnerability detection capabilities, while decentralized finance companies may focus more on regulatory risks and compliance.

Challenges in Keeping Public Chains Secure

The decentralization and permissionless nature of public blockchains allow many people to scrutinize various aspects of them. Therefore, building the necessary tools and promoting education is crucial. Factors affecting the ecosystem extend beyond the blockchain itself and include social media discussions, FUD, and potential fraud.

The three-pronged approach to keeping public blockchains secure includes: education to promote knowledge learning, information exchange to facilitate industry insights, and tools to promote action measures.

Communication Methods in the Sui Ecosystem

The Sui ecosystem communicates in various ways, including validator node summits, Builder Houses events, and more. Daily communication channels cover platforms such as Discord and Telegram, facilitating interactions between validator nodes, node operators, and other relevant parties.

The Security of Sui Move

Sui Move is relatively safer than other programming languages. The Sui development team has many members focused on security, making the various components of Sui more resilient and harder to exploit. However, security experts still need to pay attention to potential vulnerabilities and threats.

The Impact of Web3 Vulnerability Incidents on Sui

Vulnerability incidents in the Web3 space provide valuable learning experiences for security practitioners. The Sui Foundation team invests significant resources to study these threats in order to optimize and strengthen their security strategies.

Future Outlook on Web3 Security

With the development of technologies such as Web3, artificial intelligence, machine learning, and AR/VR, the security field will also face new opportunities and challenges. In the future, AI security assistants may emerge, and there could even be scenarios of AI against AI. Sui is expected to be at the forefront of the application of these advanced technologies.
