Automated CA Certificate Installation for SSL Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing SSL man-in-the-middle inspection systems require manual installation of CA certificates on client machines, which is inconvenient for users due to the need for knowledge of certificates and varying installation processes across different operating systems.
Innovation Solution
A client security manager automatically downloads and installs a CA certificate from a network security appliance into the client's certificate store, making it a trusted root certificate, thus eliminating the need for manual installation and ensuring secure connections without warning messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual installation of CA certificate is performed, then security trust is established, but user convenience deteriorates due to complex installation process
Solution Approach 1:
The system performs self-service by automatically detecting the need for CA certificate installation and executing the installation process without requiring user intervention. The security appliance autonomously generates the CA certificate, stores it securely, and manages its distribution to clients, thereby establishing security trust while maintaining user convenience.
Solution Approach 2:
The CA certificate is generated and prepared in advance by the security appliance before actual SSL inspection operations begin. This preliminary action ensures that the certificate is ready for immediate use, establishing security trust upfront while avoiding the need for complex manual installation procedures when needed.
2Ease of operation
If automatic installation is implemented, then user convenience is improved, but system complexity increases due to automated certificate management
Solution Approach 1:
The patent merges the CA certificate generation, storage, and distribution functions into the existing security appliance infrastructure. By combining these certificate management tasks with the appliance's existing SSL inspection and security enforcement capabilities, the system achieves automatic installation without proportionally increasing overall system complexity.
Solution Approach 2:
The security appliance acts as an intermediary between the certificate authority function and the client systems. It mediates the entire certificate lifecycle including generation, secure storage, and automated distribution to clients, thereby simplifying the user experience while concentrating the complexity within the appliance's managed environment.

AI summary
Systems and methods for automatically installing CA certificates received from a network security appliance by a client security manager to make the CA certificate become a trusted CA certificate to a client machine are provided. In one embodiment, a client security manager establishes a connection with a network security appliance through a network, wherein the client security manager is configured for managing security of a client at the client side and the network security appliance is configured for managing the security of traffic pass through the network. The client security manager downloads from the network security appliance a certificate authority (CA) certificate to be used for signing a server certificate of a secure connection between the network security appliance and the client and automatically installs the CA certificate into a certificate store of the client.
