Service Thread Security Hardening via Unique Identifiers

The patent segments the security management by introducing unique service identifiers (SIDs) for each operating system service within a process. Each service thread is tagged with its corresponding SID, enabling the security manager to enforce individual security rules and access control lists for each service while maintaining their grouping within a single process. This resolves the contradiction by providing fine-grained security control without requiring separate processes for each service.

The patent implements local quality by assigning unique service identifiers to specific services within a process and tagging service threads with their corresponding SIDs. This enables the security manager to apply different security policies and access control rules to different services locally, rather than applying a blanket policy to the entire process. The local quality principle allows the system to maintain a simple single-process structure while achieving precise service-level security control.

The patent implements feedback by creating a security validation mechanism where service threads are monitored and their actions are validated against access control lists specific to their service identifier. The security manager receives feedback from service thread actions and enforces appropriate security rules, blocking unauthorized actions while allowing legitimate ones. This feedback loop enables fine-grained security control without significantly complicating operation, as the validation occurs automatically in the background.
