Contractor Red Team to Test Government Cyber and Physical Defences

Sector: Government
Practice: CyberAssure — Red Team Assessment, Network Forensics, and AI-Assisted Intrusion Detection
Objective: Source and deploy a cleared, specialist red team to test real-world resilience across physical access controls and network security — and engage a Cisco network forensics specialist to analyse router log data for intrusion indicators, anomalous behaviour, and detection gaps.

Compliance Said Green. Reality Said Otherwise.

A government department operating from multiple secure facilities across Australia had a compliance problem that was not visible in its compliance results. Internal reviews and mandated audits confirmed adherence to required standards — the reports were green. But recent incidents in other agencies had demonstrated what security professionals already know: compliance checklists confirm that controls exist, not that they work. Real-world adversaries do not follow audit frameworks.

The Titanic was one hundred percent compliant — yet history shows that compliance cannot compensate for engineering vulnerabilities. The department recognised that the only meaningful test of physical and network security is an adversary who attempts to defeat it.

The department required a discreet, highly skilled red team with specialist capabilities across both cyber intrusion and physical penetration testing — and a separate capability to analyse what the network had already been logging but nobody had systematically interrogated.

The 123.EXPERT Approach

123.EXPERT sourced and contracted two specialist capabilities from its network of cleared cyber security practitioners — a red team for adversarial physical and network testing, and a Cisco network forensics specialist for router log analysis and intrusion detection. Both capabilities operated under strict rules-of-engagement protocol, with the CISO maintaining oversight and operational continuity protected throughout.

The red team:

Reconnaissance conducted across physical entry points, staff routines, access patterns, and social engineering vectors — mapping the real attack surface before any active testing commenced.
Controlled physical intrusion attempts performed — assessing door access systems, CCTV coverage blind spots, visitor management processes, and tailgating vulnerability across multiple facilities.
Wired ethernet security tested across port controls, VLAN segmentation integrity, and intrusion detection capability — establishing whether network boundaries held under active probing.
Insider threat scenarios simulated to evaluate detection speed, escalation procedures, and whether the organisation could identify and respond to a threat originating from within its own perimeter.
Vulnerabilities documented with risk ratings and prioritised countermeasures across both physical and cyber domains — producing an actionable remediation roadmap rather than a findings register.

The Cisco network forensics specialist:

Cisco router logs collected and normalised across multiple facilities — establishing a complete, timestamped record of network activity against which anomalies could be identified.
Custom Python scripts developed to parse and analyse log volumes at a scale impractical for manual review — automating the detection of anomalous traffic patterns, unusual authentication sequences, port scanning behaviour, and lateral movement indicators.
Historical log data interrogated for indicators of compromise that predated the engagement — establishing whether any intrusion activity had occurred in the period before adversarial testing began.
Script outputs correlated against the red team’s active testing activity — distinguishing between red team-generated anomalies and pre-existing or independently occurring network events.
Detection gap analysis produced — identifying where the department’s existing monitoring and alerting capability had failed to surface activity that the log analysis confirmed had occurred.

Outcome

The red team identified several actionable vulnerabilities that the compliance audit process had not surfaced — weaknesses in physical visitor verification, unmanaged network ports accessible within secure zones, and insufficient monitoring coverage in areas where detection should have been strongest. Each finding was precisely the type that a determined adversary would have identified and exploited.

The Cisco log analysis surfaced a finding of equal significance: anomalous traffic patterns in the historical log data that the department’s existing monitoring had not flagged. The custom Python scripts identified sequences of authentication failures, unusual outbound connection attempts, and low-volume port scanning activity that individually fell below alert thresholds — but when correlated across time and source, indicated systematic probing behaviour that warranted investigation. The logs had contained the evidence. The capability to read them had not previously existed.

Together the two workstreams answered questions that neither could have answered alone. The red team established what an adversary could do. The log analysis established what may already have been attempted. The combination gave the department a complete picture of its actual security posture — not the reported one.

The department moved swiftly to address the findings — upgrading physical access controls, closing unmanaged network ports, tightening VLAN segmentation, enhancing monitoring coverage, and establishing an ongoing log analysis capability to ensure the historical blind spot did not persist.

The engagement validated a principle that CyberAssure is built on: the gap between reported security posture and actual security posture is rarely visible until someone tests it — or reads what the network has already been recording. Through 123.EXPERT’s network of cleared security practitioners, the department accessed both capabilities simultaneously, in a single coordinated engagement with the clearance levels, discretion, and operational discipline a government security context demands.
