Network-Based Security and Access Control Systems

Security and access control systems are part of our daily lives, but we seldom give much thought to their complexity and all the individual components that comprise them: security cameras, DVRs, card readers, management software to control it all … the list goes on.

One component that is crucial but often overlooked is a time server.

A time server is the common reference for all elements in a security or access control system. A time server synchronizes everything on the network and delivers Legally Traceable Time®, which is critical for using video or data logs as evidence in a court of law.

Why Accurate Time is Essential for Video Surveillance and Security Programs

When It Has to Be Legally Traceable, You Need a Time Server

What kinds of systems need time synchronization?

  • Point of sale systems
  • E-commerce and online banking systems
  • Business financial and payment systems
  • Video surveillance systems
  • Access logs
  • Cashier drawers
  • Alarm logs
  • Any application where theft, civil litigation or life safety is of concern

A difference of even a minute or two can render all your evidence inadmissible and get it thrown out of court.

“If business, organization or human life depends on having correct time or can be harmed by it being wrong, you shouldn’t ‘just get it off the internet.”

How to Protect Your NTP Server from Cyberattacks

July 10, 2019
By Denis Reilly, Technical Lead Engineer
 
Network experts already know that distributing the correct time is key to maintaining their critical infrastructure programs. However, keeping accurate time is also fundamental to many cybersecurity applications. Over the last few years, there has been significant research into ways that the NTP protocol can be secured from malicious attackers.

Not All GNSS-Based Time Servers Are Created Equal

GNSS itself has some vulnerabilities. Jamming and spoofing are two different ways that bad actors can attack GNSS systems.

GNSS jamming is when an interference signal is deliberately broadcast to drown out the GNSS signal, causing the reference to be lost.

GNSS spoofing is the act of broadcasting a fake GNSS signal to trick receivers into thinking they are in a different location. For example, if a building had automatic locks on a timer and a bad actor changed the time, he could unlock those doors.

As security and access control systems become more complex, the risk of vulnerability increases exponentially. That makes time synchronization even more critical.

STL Option

As an encrypted signal 1000x stronger than GNSS, STL is an ideal solution for augmenting GPS or other GNSS constellations for resiliency and security or as a standalone indoor solution when roof access isn’t an option.

8230AJ Anti-Jam Antenna

8230AJ GPS/GNSS Anti-Jam Outdoor Antenna

The Model 8230AJ is a high gain (40 dB) GNSS outdoor antenna. It uses a three-stage low noise amplifier, a mid-section SAW, and a tight pre-filter to protect against saturation by high level sub-harmonics and L-band signals. The Anti-Jam antenna rejects signals for the lower elevation angles – where most of the interference comes from.
