VANGUARD Protects Against Fiber Network Attacks at the Physical Layer

The Challenge

Threats to an organization’s data security and network availability are greater than ever, and aggressors are more organized, technologically competent and well funded. Gartner reports that global IT security spending will reach nearly $77 billion in 2015 in response to this growing concern.

While organizations are spending heavily on cyber security plans to prevent intrusion within the active portion of their networks, many companies fail to address the physical network infrastructure – the optical and copper cabling carrying the critical data – which is a drastically under-publicized point of vulnerability. A single fiber carries vast amounts of information, making fiber optic cables valuable targets for attackers.

Gartner also reports that 75% of all network cabling is located in publicly accessible spaces. This makes them not only vulnerable but also easy to access. As with copper cables, it is simple to insert a tap onto a fiber optic cable.

In addition, denial-of-service attacks – purposefully severed backbone cables causing widespread Internet outages and disruptions in phone service and computer transactions – are occurring with more frequency.

Whether an errant maintenance activity or a deliberate act of terrorism or espionage, the cost of a cyber security incident is high and in some cases can be catastrophic.

Our Solution

Certain industries have a critical need to safeguard the confidentiality and availability of their data just as the government protects its National Security Information. Fortunately, private enterprises can now draw on the same technology used by the U.S Government to protect its fiber optic infrastructure carrying classified data.

Network Integrity Systems (NIS) – a leader in developing network security solutions for the U.S. Department of Defense and other government agencies – has now developed a similar technology for private enterprises.

The VANGUARD™ product line ensures the integrity and availability of an organization’s network data by performing continuous monitoring of the fiber optic network infrastructure. It detects and reports any changes or behavior that would indicate tampering with the cable.

VANGUARD reduces risk to an organization by identifying harmful events before they are carried out – whether a precursor to an attack or inadvertent damage that could degrade network performance or availability.

VANGUARD Enables Fiber Optic Network Infrastructure Protection

  • Real-time Monitoring & Situational Awareness Centrally Managed from Anywhere in the World
  • Integrated Network Physical Security
  • Early Threat Detection, Affording Time to Act and Greater Potential to Prevent Damage or Theft of Data
  • Automatically Adapts to Environment (No false alarms)
  • Flexible Incident Reporting & Response
  • Interoperability with Existing Security Systems
  • Ability to Shut Off Data if Threat is Detected by Incorporating Ancillary Products & Software
  • Fiber Forensics™ Provides Investigators with Critical Information to Assist in Profiling Methods of Attack, Helping to Prevent Future Attacks.


VANGUARD ensures the integrity and availability of network data by monitoring spare strands of fibers (or active data fibers in certain applications) within optical cables making up the network infrastructure. This 24/7/365 continuous monitoring allows the system to immediatley detect and report any changes or behavior that would indicate tampering with the cable system as a precursor to an attack. Smart-filtering™ technology eliminates false alarms by learning the normal day-to-day activity within the environment. With plug-and-play capability, VANGUARD can be rapidly added to new or existing network infrastructure.

VANGUARD acts as a complement to your existing cyber security hardware and software. The alerts and information from VANGUARD can be integrated into existing facility Intrusion Detection Systems (IDS) to alert security personnel as well as into existing Network Management Systems (NMS) to alert network administrators. VANGUARD leverages standards-based protocols and interfaces to provide interoperability for integration within your environment.

Optionally, The VANGUARD CS solution can be centrally managed from anywhere in the world and provide first responders with an early warning, affording them time to act and greater potential to prevent damage or theft of data. A unique benefit of the CS solution called Fiber Forensics™, provides investigators with critical information to assist in profiling methods of attack, helping to prevent future attacks.
