DC0082: Network Connection Creation
The initial establishment of a network session, where a system or process initiates a connection to a local or remote endpoint. This typically involves capturing socket information (source/destination IP, ports, protocol) and tracking session metadata. Monitoring these events helps detect lateral movement, exfiltration, and command-and-control (C2) activities.
*Data Collection Measures:*
- Windows: - Event ID 5156 – Filtering Platform Connection - Logs network connections permitted by Windows Filtering Platform (WFP). - Sysmon Event ID 3 – Network Connection Initiated - Captures process, source/destination IP, ports, and parent process. - Linux/macOS: - Netfilter (iptables), nftables logs - Tracks incoming and outgoing network connections. - AuditD (`connect` syscall) - Logs TCP, UDP, and ICMP connections. - Zeek (`conn.log`) - Captures protocol, duration, and bytes transferred. - Cloud & Network Infrastructure: - AWS VPC Flow Logs / Azure NSG Flow Logs - Logs IP traffic at the network level in cloud environments. - Zeek (conn.log) or Suricata (network events) - Captures packet metadata for detection and correlation. - Endpoint Detection & Response (EDR): - Detect anomalous network activity such as new C2 connections or data exfiltration attempts.

Executive priority
DC0082: Network Connection Creation is an official MITRE ATT&CK data component. Glexia treats it as defensive behavior context for prioritizing monitoring, control validation, and response planning without using the object by itself as an attribution claim.
Technical view
Security teams should validate DC0082: Network Connection Creation by reviewing the official ATT&CK relationships, mapped tactics (the mapped ATT&CK tactic context), supported platforms (the platforms named in the official object), and available local telemetry before making detection or mitigation decisions.
Likely telemetry
- Official ATT&CK relationships and object metadata
Detection direction
- Validate whether DC0082: Network Connection Creation appears in your detection coverage and tabletop scenarios.
- Use the object to align executive risk language with SOC, incident response, and detection engineering work.
- Do not treat ATT&CK relationship context as attribution without corroborating evidence.
Mitigation priorities
- Map the object to existing controls and identify missing telemetry or response ownership.
- Prioritize mitigations that reduce exposure on the listed platforms and tactics.
- Review adjacent ATT&CK relationships before changing policy, detections, or reporting language.
Additional notes and limits
Baseline Glexia take generated from the official MITRE ATT&CK STIX object, source hash, tactics, platforms, and detection fields. It is safe to replace with a richer model-generated take for the same source hash later.
This baseline take is source-grounded and schema-validated, but it does not include environment-specific telemetry, incident evidence, or threat-intelligence corroboration.

Mirrored ATT&CK source object
The raw object is retained through the mirrored ATT&CK source bundle and object hash. The raw endpoint returns the exact object from the mirrored bundle when available.
External references and citations
MITRE external references are preserved separately from Glexia analysis so citations remain traceable to their original source records.
