Physical Security Information Management (PSIM): The Basics

Added 11th Oct 2010

The concept that's become known as Physical Security Information Management (PSIM, pronounced P-sim) was introduced to the physical security world in 2006. The idea is that all the stuff of security is actually data. Data that, once contextualized and analyzed, becomes information for making better business decisions. It is applying the concepts of information management and business intelligence to the practices and technologies of physical and homeland security.

In a companion article you'll find a list of specialized PSIM solution providers.

Why PSIM matters
First, some background. At the moment, improvisational, fragmented, off-the-cuff security management is the norm. It's common to find security operations and traditional command-and-control centers using paper-based processes and not sharing information. Business units and IT departments rarely have access to data in corporate (a.k.a. physical) security departments. Events are managed separately.

Access-control-related events are monitored and managed separately from intrusion detection systems, and separate also from environmental sensors and other alerting systems. Many times the people and systems are not even located in the same facility, inhibiting information sharing and correlating. Computers, software and networking are still approached with suspicion. While most security departments use personal computers and digital video storage, there is not a general acceptance of interoperability between systems, or of information sharing in general.

Unfortunately, it's likely that current trends will widen this gap even further.

Enter Physical Security Information Management

PSIM is the foundation of next-generation security management. It's not a single product, but rather a set of processes and supporting technologies for physical security management and reporting.

Effective PSIM requires both integration of technologies and coordination with the IT and security processes governing the management of organizational data. The theory has thrived amid dynamic change in the security industry precisely because of its composite nature and multiple benefits. PSIM helps extend security services, improve efficiency and effectiveness, and allow for better accountability. There are several key trends making it more valuable and affordable today:

-- Data management best practices are more pervasive. Regulatory compliance and management best practices dictate that computer systems and data be handled in standardized ways, such as according to the guidelines established by the International Organization for Standardization. Security departments are, in general, not compliant with these best practices.

-- Business executives are demanding more data. Business decisions are made throughout organizations by analyzing data. Security departments will be forced share security and risk data in ways business executives can understand and appreciate.

-- Software for aggregating and correlating security data is more available. (See, for example, SIEM: Dos and don'ts for security information and event management.) Innovations in software development make traditional processes seem less modern.

-- Businesses continue to adopt computers, software and networking for performing critical functions. This makes data more available and automation more easily employed.

-- The costs of networking sensors and systems continue to drop.

Situation management--one way PSIM is applied

PSIM principles may be used to produce better situational awareness, prompting better security and business decisions. Situation management software creates useful information out of raw video by contextualizing it--unifying video, alarm and sensor data--which improves situational awareness and makes incident responses more efficient.

Many access-control and video management products perform very basic situation management. They may link video of someone walking through a door to a log of when a keycard is swiped there, or associate security camera footage with individual point-of-sale transactions.

But situation-management software is far more sophisticated, capable of visually presenting multiple related events as a single group. It can combine the several separate sets of information registered during a break-in, for example: the door-open alert from access control; the lock-failure alert from a keycard system; the motion-detection alert from a hallway sensor; the video feeds from two or three nearby cameras. The software combines all this into a single view of the available information.

Security directors want to know what's going on, so they install surveillance cameras, alarms and intrusion-detection systems, and hire security guards. But although these precautions may answer the question, "What's happening?" they aren't much help with the follow-up questions, "How important is it?" and "What should I do about it?"

That's because they don't correlate the activities they record with those registered by other systems. Therefore, the security personnel watching the cameras may not have enough information to recognize that the person who seemed to swipe his card and walk through the door was not in fact granted access. Similarly, the access-control system recorded the door opening, but it didn't associate it with the simultaneous lock failure. The individual systems still think everything is fine.

Customers know they need a solution to this problem. The security-advisory firm I founded, Hunt Business Intelligence, interviewed 15 security-system integrators and 40 executive-level security directors about how they plan to deploy PSIM over the next 18 months. Although most organizations were not familiar with the theory, nearly all of them described a desire for improved situation management. To get it, they were turning to integrators, alarm-monitoring equipment, and access control and video management systems.
