Important Security Precepts

Physical Security Vulnerability

The concept of total security is fraught with problems. Perfect or absolute security is always the goal of security practitioners responsible for the protection of a facility or activity, but such a state of absolute security can never be fully obtained. The permutations to consider are in constant flux and calibrations and recalibrations are necessary. There is no asset so well protected that it can never be stolen, damaged, destroyed, or undermined by unauthorized individuals. For that reason a balanced, multilayered security program, informed and design after a thorough security vulnerability assessment provides protection against defined set of threats by informing the user of attempted intrusions and providing resistance to the would-be intruder’s attack paths. This resistance must be consistent around the intended asset protected perimeter area.

There are four main security elements that should be properly integrated in order to achieve a proper balance of physical security. They are:

  • This is the process of detecting and locating intruders as far from the protected areas as feasible. Early detection gives the user more time for effective alarm assessment and execution of pre-planned response.
  • Assessment is determining the cause of the alarm or recognizing the activity. This must be done as soon as possible after detection to prevent the intruder’s position from being lost.
  • Intruders must be delayed long enough to prevent them from achieving their objectives before the response force can interdict them.
  • A response force must be available, equipped, and trained to prevent the intruders from achieving their objective. The response time must be less than the delay time if the response force is to intercept the intruders before they achieve their objective.

Meet Bob

While monitoring information channels, I came across a thought-provoking article related to the application of a robot, appropriately named Bob (As of now in the research stage) to the task of building security. The immediate reactions are to associate this adaptation of advance robotics andAi, setting aside the inherent weaknesses in this technology platform, with two very sensitive areas of our current economic model, that of replacing human labor with technology at a time when there remains soft pockets of labor markets in the global economy. There is also a more acidic view, that of another creepy intrusion of advance technology into personal privacy as such “droids” may lend themselves to abuse either willingly by its operators or unwillingly by malicious intrusion from hackers exploiting flaws in its software architecture.

But there is another reading to this. For years we in the security profession have been witnesses to the convergence of physical and logical security, where in many cases these two separate ops centers functioned seamlessly. In other words the same command and control centers that handle cybersecurity and other InfoSec countermeasures also integrate surveillance, access control and the human (security officer) interactions forming a concentric mesh of enterprise protection. I see the development of new nodes, such as robotic technology powered by the latest in artificial intelligence technology as an inevitable evolution in the converged ecosystem. The challenge will be to leverage the new technology to plug gaps in existing security programs with augmented nodes of information. For instance this would take the surveillance technology which is for the most part fixed on particular locations and make it mobile and interactive with people occupying the space where deployed. Furthermore, promising technology such as facial or pattern recognition which has yielded limited results in protection schemes could have more effective applications when loaded onto a roaming droid.

These are just quick reflections on this development. In time we can come up with more sophisticated approaches to the application of robotic technology to protection programs and more importantly in a way that’s not detrimental to our privacy and to the millions of men and women that depend on the security profession as a livelihood.
