This fictional report shows our deliverable format. All environment details, evidence, observations, and priorities below are hypothetical. They are not client results or an assessment of your systems.
Rhenium Security / Sample deliverable
Palo Alto Networks Firewall Health Check
Example scope: One active/passive NGFW pair managed by Panorama. Synthetic configuration excerpts, topology notes, and status snapshots.
Executive summary
This example identifies four issues affecting administrative exposure, policy enforcement, monitoring visibility, and failover readiness. The proposed sequence establishes a recoverable configuration baseline, restricts management access, stages policy improvements, and verifies logging and HA behavior.
Production changes and failover testing require a separately agreed change plan. Actual severity depends on exposure, compensating controls, business impact, and evidence quality.
The example management interface is reachable from general user networks. Its permitted-address list is empty, with HTTPS and SSH enabled. See synthetic evidence E01.
Why it matters
More hosts can reach administrative services than the stated management design requires.
Recommended action
Restrict management access to approved administrative hosts and necessary services. Confirm the access and recovery paths before changes. Review authentication and MFA alongside source restrictions.
Verification
Within the agreed change window, confirm approved administrators retain access and an unauthorized test source cannot reach administrative services.
The synthetic rule “corp-outbound” allows the user zone to the internet zone with application and service set to “any.” No security profiles are attached. See synthetic evidence E02.
Why it matters
Access extends beyond a defined application requirement, and the inspection provided by attached security profiles is absent from this rule.
Recommended action
Identify required applications and dependencies, then stage narrower rules with application owners. Apply an appropriate security profile group, accounting for licensed capabilities and inspection limits.
Verification
Validate policy matches and representative business transactions. Confirm the intended profiles are attached and expected inspection events appear during agreed validation.
The synthetic rule “approved-web” has session logging disabled and no forwarding profile. The example monitoring design requires these events centrally. See synthetic evidence E03.
Why it matters
Missing events reduce the evidence available for troubleshooting and security investigation.
Recommended action
Configure logging suited to traffic and retention requirements, attach the appropriate forwarding profile, and validate its destination. Consider how long-lived sessions affect visibility.
Verification
Generate an agreed benign transaction and confirm the expected event appears locally and at the destination with usable timestamps and rule identity.
HA configuration synchronization needs reconciliation
Observation
Synthetic snapshots show configuration synchronization disabled and running configurations out of sync. The intended design is a synchronized active/passive pair. See synthetic evidence E04.
Why it matters
A failover could apply different policy or settings, creating unexpected access or service behavior.
Recommended action
Compare the peers and establish the intended configuration. Confirm backups and rollback steps before synchronization, accounting for settings that do not synchronize automatically.
Verification
Confirm expected peer states and synchronized running configuration. Validate failover and application continuity only within an agreed maintenance plan.
Local: active. Peer: passive. Configuration synchronization: disabled. Running configuration: out of sync.
Remediation roadmap
Establish the change baseline.Confirm owners, backups, intended peer configuration, and rollback criteria.
Reduce administrative exposure.Apply and verify the agreed management boundaries.
Stage policy improvements.Validate application requirements and security profile coverage with business owners.
Close operational gaps.Confirm log delivery, reconcile HA configuration, and schedule any required failover validation.
Engineering readout
Review each finding against the intended architecture, confirm business exceptions, assign owners, and agree on verification evidence. Record open questions and dependencies before implementation begins.
