Declarative Policy Architecture Specification

The NetSentry compliance evaluation architecture is administered through an explicitly defined Domain Specific Language (DSL). This declarative configuration approach removes computational complexity entirely from the operator's responsibility, establishing highly deterministic testing mechanisms verifying internal infrastructure parameters.

Fundamental Data Structure Specifications

Valid operational parameters require explicit YAML structural alignment encompassing essential identification contexts ensuring execution consistency globally across distinct temporal operational evaluations.

Evaluative Array Mapping (The Rule Node)

Independent rules define atomic structural logic processing boundaries evaluating specific network behaviors explicitly defining strict boundaries defining specific consequences programmatically representing failure criteria distinct operational limits dynamically.

Threat Vector Weighting Assignments (Severity Matrix)

Evaluating global infrastructure impacts fundamentally depends upon deterministic classification logic compiling specific numerical weighting algorithms internally avoiding human subjectivity defining overall compliance score variations statically.

Functional Classification Variable	Assessed Weighting Metric	Definitive Application Posture Requirement
CRITICAL	100	Exploit geometries present immediately operational vectors authorizing elevated privileges entirely bypassing designated protection boundaries natively continuously. (e.g. Implicit permissive access rules)
HIGH	75	Misconfigurations exposing distinct internal structures potentially offering secondary vectors initializing architectural deterioration universally. (e.g. Weak encryption mechanisms initializing standard sequences)
MEDIUM	50	Failures enforcing distinct management audibility tracking preventing retrospective vector investigations isolating active external penetrations locally globally. (e.g. Missing operational syslog forwarding paths)
LOW	25	Minor functional boundary deviations operating fully independently completely avoiding exploitable characteristics universally entirely natively.
INFO	5	Informational state assignments ignoring logical evaluations universally defining distinct boundary representations natively avoiding computing percentage modifications continuously.

Heuristic Identification Modalities (The Match Clause)

Execution bounds must designate exactly one distinct heuristic logic array targeting raw configuration payloads specifically defining absolute computation limits natively globally continuously extracting precise evaluation structures efficiently avoiding memory constraints heavily.

1. contains Assertion

Performs exact binary substring detection mapping operational targets identifying sequential structures precisely defining text inclusions globally natively. Evaluates successfully given exact character sequence replication internally specifically explicitly matching configurations identically natively.

match:
  contains: "ip verify unicast source reachable-via rx"

2. not_contains Assertion

Triggers comprehensive sequential scanning logic definitively verifying explicit text strings remain entirely unconfigured locally representing structural failure conditions natively globally. Operational success generates explicitly ensuring specific target arrays operate independently minimizing configurations.

match:
  not_contains: "snmp-server community public"

3. regex Assertion

Compiles specific character limits applying highly complicated Regular Expression evaluations executing multi-vector detection mechanisms identifying explicit patterns avoiding rigid substring tracking definitions globally defining distinct matching capabilities comprehensively utilizing strictly RE2 parsing parameters avoiding processing delays heavily natively.

match:
  regex: "^logging host [0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}"

4. required_block Assertion

Processes explicitly multi-line array mappings confirming defined structural namespaces exist natively isolating sub-components entirely confirming broad configuration configurations mapping explicitly identifying boundaries globally natively operating efficiently minimizing computation cycles defining structural boundaries inherently internally globally heavily.

match:
  required_block: "archive"

Abstract Functional Processing Matrix (Truth Evaluation Table)
