Field Audit Report: Edge Computing Nodes & Cell Tower Physical Security Assessment

1. Site Coordinates & Cell Tower Metadata

Document the essential identification and location details for the audited telecommunications site. All coordinates and metadata must be recorded with precision to ensure traceability and correlation with network management systems.


Unique Site Identifier (Site ID)

Site Name or Alias

GPS Latitude (Decimal Degrees)

GPS Longitude (Decimal Degrees)

Tower Structure Height (meters)

Tower Structure Type


Edge Computing Node Serial Number

Audit Start Timestamp

Last Scheduled Maintenance Date


Is the site access logbook physically present and intact?


Current Weather Condition During Audit

Site Criticality Level (1=Low, 5=Critical Infrastructure)

Upload wide-angle photo of entire site from primary access point

Choose a file or drop it here

Upload close-up photo of Site ID plaque or identifier

2. Physical Enclosure & Perimeter Breach Assessment

Conduct a thorough examination of the physical security perimeter, enclosure integrity, and all access control mechanisms. Any indication of tampering, forced entry, or environmental compromise must be documented with photographic evidence and detailed narrative.


Is the perimeter fence or wall fully intact with no visible damage?


Are all perimeter gates secured with functional locks?


Primary Gate Lock Mechanism Type

Is the electronic access control system operational?


Are all surveillance cameras recording and properly positioned?


Is there evidence of unauthorized personnel presence (footprints, litter, tools)?


Are there signs of forced entry attempts on any enclosure doors?


Overall Perimeter Lighting Adequacy

Are there any environmental hazards present (flooding, fire damage, chemical spills)?


Select all security measures observed at the site:

Upload photo of main gate and access control panel

Choose a file or drop it here

Upload photo of any perimeter damage or breach points

Choose a file or drop it here

Upload photo of surveillance camera positioning (if accessible)

Choose a file or drop it here

3. Rogue Hardware & Physical Keylogger Inspection

Perform detailed internal inspection of edge computing enclosures, server racks, and all physical interfaces. Focus on detecting unauthorized devices, physical keyloggers, cable tampering, and any anomalies in hardware configuration. All findings must be photographed and catalogued.


Is the edge computing node enclosure seal intact and untampered?


Are all server rack doors securely locked?


Have any unauthorized hardware devices been discovered inside the enclosure?


Were any physical keyloggers or covert recording devices found attached to keyboards or consoles?


Is all cabling properly labeled and routed through authorized cable management?

4. RF Signal & Optical Fiber Diagnostics

Execute comprehensive radio frequency spectrum analysis and optical fiber infrastructure diagnostics to detect anomalies, unauthorized transmissions, signal interference, or physical fiber taps. Record all measurements and capture diagnostic screenshots for evidence.


Baseline RF Signal Strength (dBm) at Primary Frequency

Are there any unauthorized or anomalous RF transmissions detected within 50m radius?


Is there evidence of RF interference or jamming affecting legitimate services?


Are all optical fiber cable jackets intact with no signs of physical tapping?


Optical Fiber Signal Loss Measurement (dB) on Primary Trunk

Was an OTDR (Optical Time Domain Reflectometer) test performed?


Rate the condition of optical fiber connectors and patch panels

Poor

Fair

Good

Very Good

Excellent

Connector Cleanliness

Proper Labeling

Physical Security (Locked)

Dust Cap Presence

Bend Radius Compliance

Are there any unauthorized optical splitters or couplers discovered?


Spectrum Analyzer Equipment Used
