Definition of System Vulnerabilities

Vulnerability is flaw or weakness in system security procedures, design, implementation, or internal controls that could be exercised (accidentally triggered or intentionally exploited) and result in a security breach or a violation of the system’s security policy.

Notice that the vulnerability can be a flaw or weakness in any aspect of the system. Vulnerabilities are not merely flaws in the technical protections provided by the system. Significant vulnerabilities are often contained in the standard operating procedures that systems administrators perform, the process that the help desk uses to reset passwords or inadequate log review. Another area where vulnerabilities may be identified is at the policy level. For instance, a lack of a clearly defined security testing policy may be directly responsible for the lack of vulnerability scanning.

Here are a few examples of vulnerabilities related to contingency planning/ disaster recovery:

• Inadequate information system recovery procedures, for all processing areas (including networks)
• Not having alternate processing or storage sites
• Not having alternate communication services
• Not having clearly defined contingency directives and procedures
• Lack of a clearly defined, tested contingency plan • The absence of adequate formal contingency training • Lack of information (data and operating system) backups

Research on Network Architecture and IPv6 Technology

Undertake the National High Technology Development 863 Program of China, key projects of National Natural Science Funds and the projects of National Basic Research Program of China collaborating with the Department of Computer Science of Tsinghua University. Develop the research on (1) next generation Internet architecture, and (2) IPv6 Source Address Validation Architecture .

Develop the research on the architecture and key technologies of next generation routers and switches, and high performance IPv4/IPv6 transition and interoperation methods. Developed the first IPv6/IPv4 dual-stack core router (BitEngine 12000 Series) in China, collaborating with the Department of Computer Science of Tsinghua University and Tsinghua Bitway Networking Co. Ltd.
