Introduction: The Scope of the DOI Mission

Safeguarding the DOI's vast natural resource data, personnel records, and critical infrastructure telemetry is an unrelenting task. Evolving cyber threats against civilian agencies could compromise national resources or expose citizens' data.

Axcend delivers the cornerstone of the DOI's defensive posture with continuous IT security monitoring, proactive event analysis, and rapid incident response capabilities.

Establishing the Defensive Posture

Our mission relies heavily on SOC tool operations and maintenance, tightly integrated with strict change and release management practices. We correlate alerts to ensure analysts aren't drowning in noise from disparate security tools.

Axcend SOC Threat Mitigation Pipeline

Ingestion & Telemetry Tuning

Tuning defensive tools (SIEM, EDR) to drastically reduce false positive security alerts across the DOI network.

Event Analysis & Threat Hunting

Deep-dive digital forensics and vulnerability assessments to categorize anomalies in real-time applying MITRE ATT&CK mapping.

Incident Response & Recovery

Swift containment and systematic recovery protocols led by Axcend Incident Response handlers.

Deep Dive into Telemetry & Tuning

By continually tuning defensive IT security system configurations, we significantly reduce "alert fatigue", freeing analysts to focus on high-priority threats. Axcend engineers deploy custom parsing scripts and threat intelligence integrations to enrich incoming data logs.

Incident Response Protocol

Our responders conduct proactive vulnerability assessments and apply threat intelligence to hunt adversaries before a breach occurs, scanning the environment for illicit beacons and zero-day exploitation artifact trails.

Axcend Tactical IR Phases

T+0m: Detection & Triage

Analyst identifies confirmed malicious payload on endpoint via EDR.

T+15m: Network Containment

Host is network-isolated using EDR platform. Lateral movement halted.

T+2Hr: Forensic Acquisition

Memory dumps and MFT tables extracted for root cause analysis.

T+24Hr: Eradication & Recovery

Payload purged, vulnerabilities patched, active directory accounts rotated.

Our rapid recovery efforts ensure minimal operational downtime for DOI services. Axcend provides comprehensive post-incident reporting to CISO stakeholders, documenting infrastructural changes to prevent recurrence.
