MODULE 02 // LAYER ARCHITECTURE

LAYER ARCHITECTURE

How ABIS operates as an intelligence layer above your systems

6 Modules
4 Hours
Foundation Level
01
Layer Architecture

Stack Position

Behavioral intelligence is not a monolithic service. It's a layer. Understanding where ABIS sits in your architecture determines how effectively it protects your system.

Topics Covered
  • Layered architecture principles
  • Horizontal security layer placement
  • API gateway integration
  • Request flow directionality
  • Fallback strategies

02
Middleware Integration

Middleware Position

Strategic positioning determines everything. Place ABIS correctly in your middleware chain, and you gain security without sacrificing performance.

Topics Covered
  • Middleware order and placement
  • Selective vs global middleware
  • Async execution patterns
  • Fail-open behavior
  • Conditional middleware application

03
Security Layer

Defense in Depth

ABIS is not a replacement for existing security—it's an additional layer. Effective security architecture means designing ABIS as a checkpoint that enhances UX.

Topics Covered
  • Layered security model
  • Separation of analysis and enforcement
  • Graceful degradation
  • Risk-based step-up authentication
  • Comprehensive audit logging

04
Latency Optimization

Speed Optimization

Every millisecond matters. Adding ABIS to your stack shouldn't degrade user experience. Optimize latency through parallelization, timeouts, and intelligent request routing.

Topics Covered
  • Latency budget allocation
  • Parallel execution
  • Aggressive timeouts
  • Connection pooling
  • Payload minimization
  • Request batching

05
Caching Strategies

Intelligent Caching

Caching ABIS responses reduces latency and API costs. But cache behavioral data incorrectly, and you'll miss real-time threats. Balance freshness with performance.

Topics Covered
  • Cache strategy patterns
  • Multi-tier caching
  • Risk-based TTL
  • Cache invalidation
  • Probabilistic early refresh

06
Circuit Breaker

Resilience Patterns

When ABIS fails, your application shouldn't. Circuit breakers prevent cascade failures, protect system resources, and enable graceful degradation during outages.

Topics Covered
  • Circuit breaker states
  • Failure threshold configuration
  • Half-open state testing
  • Fail-open behavior
  • Metrics and monitoring
