The known-knowns, known-unknowns and unknown-unknowns of network security

While tracking cybersecurity and breach mitigation issues, I sense there are known-knowns, known-unknowns and many unknown-unknowns relative to network security.


In fact, experts say it is highly probable that your network has already been hacked, that the bad-actors are already inside your network, and that whatever you do next, the perpetrators will be one step ahead.


This is a scary predicament filled with known-unknowns and unknown-unknowns, and yet the industry as a whole fails to have an open and honest dialogue concerning some known-knowns – that is, we can plan, build and operate more secure local area networks with a Passive Optical LAN because:

  • Fiber cabling is far more secure than copper cabling
  • Centralized intelligence and management ensures consistent policies and procedures
  • Tight network access controls, with role-based access, protects against malicious, and negligent, human actions
  • The ONTs have no local management access, eliminating human interaction
  • The ONTs do not store user or network information locally
  • Therefore, Optical LAN  reduces network points of vulnerability

It is encouraging to see that the Armed Forces Communications and Electronics Association (AFCEA) recently ran two articles of interest in their magazine dedicated to the topic of securing critical infrastructure:

  1. DHS Invests in Securing the Financial Infrastructure
  2. Universities Schooled on Cybersecurity

These articles are promising as they appear to be precursors to commercial industries, like Financial and Education, reaching out to the U.S. Defense, Civilian and Intelligence IT security experts for guidance on cybersecurity and breach mitigation. Of course, it is already well-known that the U.S. Federal Government is an early adopter of Tellabs Optical LAN specifically because of its superior advanced security qualities.


As for other unknown-unknowns, you’ll just have to keep watching our website and follow us on FacebookLinkedInTwitter, Instagram, Google+ and YouTube to learn when the unknown-unknowns become known-unknowns, or even better yet, known-knowns.
