Network Security

Product

It is imperative for safety-critical users such as defense, police, airports and marine ports to detect, localize and take countermeasures against malicious and unintentional radio interference. 

  • Real-time spectrum surveillance scanner.

  • ‘Picks up suspicious or anomalous radio activity is taking place in an area.

  • Highly configurable detection algorithms can be frequently changed and updated remotely.

  • Can be deployed in the field in sensitive locations.

  • Alerts when anomalies in the regular spectrum pattern are detected.

Scenarios

Detecting IMSI Catchers

IMSI catchers and ‘Stingrays’ are devices used to intercept wireless traffic and trace subscribers by their long-term identifiers (IMSIs). They pose a threat to subscriber privacy.

  • Create and use a signature footprint of the monitored spectrum

  • Set predetermined alarm thresholds outside of expected radio environment conditions

  • Anomalous activity will be detected using a subset of floor51’s signal analysis techniques, based on power anomalies, frequency drift and signature analysis

  • IMSI catchers appear as higher power neighbour cells, and so will be reliably detected

FEATURES

CHALLENGE

Detecting Jammers

Jamming attacks are a subset of denial of service (DoS) attacks in which malicious nodes block legitimate communication by causing intentional interference in networks.

  • Identify missing neighbor cells

  • Identify anomalous activity, specifically if encryption is disabled

  • Automatically identify and tune a second SDR to each signal of interest

FEATURES

CHALLENGE

Detecting Unlawful and Self-installed Enhancers

Self-installed enhancers increase radio interference in licensed spectrum, i.e. static mobile repeaters for indoor use or low-gain mobile phone repeaters for use in vehicles.

  • Conduct frequency drift and jitter analysis to identify that equipment isn’t of the same quality as the real base stations 

  • Interference investigations and obtaining evidence to allow enforcement is expensive and time consuming
