Agentic systems without context overload
How an agentic system manages the context window through Journal, Review, and Timeline, reducing latency and improving consistency in multi-agent reasoning.
Security
Security on ThecoreGrid focuses on protecting modern distributed systems through practical, production-grade engineering.
We cover application and infrastructure security across cloud-native environments, including identity and access management, zero-trust architectures, secrets handling, and secure service-to-service communication. Topics include threat modeling, vulnerability management, supply chain security, and hardening of CI/CD pipelines and runtime environments. We analyze real-world trade-offs between security, performance, and developer velocity, along with strategies for detection, response, and recovery. Content is grounded in BigTech practices, incident post-mortems, and lessons from security failures at scale. You’ll find deep dives into observability for security, policy enforcement, encryption, and multi-tenant isolation. Instead of generic checklists, the Security tag delivers actionable engineering insights for backend and platform engineers, DevOps teams, SREs, and architects responsible for building resilient and secure systems.
Kubernetes Gateway API instead of Ingress NGINX
Migration from Ingress NGINX is becoming mandatory: EOL and vulnerabilities make the transition to Kubernetes Gateway API a matter of resilience and security. The problem does not manifest immediately — until control over incoming traffic becomes a point of systemic risk. Ingress NGINX has long been the de facto standard for Kubernetes, but its lifecycle … Read more
Symbolic execution for BPF malware analysis
Symbolic execution simplifies the analysis of BPF malware and eliminates a bottleneck in reverse engineering. This approach allows for the automatic reconstruction of “magic” packets to trigger backdoors. The problem does not manifest immediately — until the analysis of BPF malware encounters the complexity of the filters themselves. The classic Berkeley Packet Filter operates as … Read more

Piracy Shield Breaks the Network Model Through Uncontrolled Blocking
The Italian blocking scheme Piracy Shield puts providers in a position to choose: violate network architecture or face fines. The conflict illustrates where regulation begins to influence infrastructure behavior.
Observability: When Security Intercepts Traffic Before the Application
Sometimes the system “breaks” even before entering the application. This case is about how the security layer completely obscures the behavior of the backend. Observability
