The Physical Security Threat Landscape

Similar to the cyber security attacks that have been experienced by many electric utilities, physical security threats are also on the rise. As stated in the news, attacks on electrical systems were up by nearly 80% in 2022 compared to the previous year.

Prominent examples of this are the Pacific Gas and Electric Company's Metcalf transmission substation shooting in 2014, more recently the coordinated attack in North Carolina on two electrical substations, and an incident in which the FBI said it foiled an alleged plot to attack multiple substations and transformers around Baltimore (PBS). These also follow recent physical attacks on electrical stations in Oregon and Washington.

As noted in a CNN news report entitled “A Vulnerable Power Grid is in the Crosshairs of Domestic Extremist Groups” (CNN); “CNN - Gunshots fired at two power substations in Moore County, North Carolina, late last year left 45,000 homes and businesses without power and more attacks just like that could already be planned by domestic extremist groups, according to experts.

This typically very primitive style attack equals millions of dollars in damage,” Brian Harrell, a former US Department of Homeland Security Assistant Secretary for Infrastructure Protection, told CNN. “If you were to shoot out some very key components you can quickly create an effect where this large multimillion dollar transformer becomes essentially a paperweight.

This, combined with the many attacks on substations related to copper theft, which sometimes results in power outages, clearly shows that physical security threat has become a major concern for critical infrastructure facilities. Advanced threat actors will use a combination of a physical breach coupled with a cyber breach to maximize the overall impact of the attack.

End-To-End Physical Security Services Provided by Acumen, Paladin and Util-Assist

To address and minimize potential physical security threats and vulnerabilities, AESI-US, Inc. (Acumen) provides a holistic approach to both Cyber and Physical Security. In partnership with Paladin Technologies and Util-Assist, our team provides an end-to-end physical security solution for utilities to manage and minimize their physical security risk. A strong physical security program enhances, mitigates, and supports the resilience of an organization in the face of adversity.
A holistic physical security solution includes:

  1. A Physical Security Assessment to identify any threats and vulnerabilities
  2. The development of a Physical Security Plan (PSP) which provides practical physical security solutions and mitigations to address the identified threats and vulnerabilities
  3. The implementation of the PSP, which includes but is not limited to, physical security solutions such as:
    • Physical security monitoring and control
    • Live video surveillance
    • Development of physical security governance, strategies, standards and policies and procedures
    • Physical security training
  4. On-going continued assessment and monitoring to ensure the physical security solutions are effective - Deter, Detect, Active Deterrence, and Defend.
  5. Integration with the cyber security program for a holistic approach to security.

Physical Security Threat and Vulnerability Risk Assessment

A Physical Security Threat and Vulnerability Risk Assessment (PSA) examines the overall physical security of facilities and buildings, specific equipment within the building’s facilities, and the geographical locations of the facilities, while factoring in key business objectives.

The objectives of conducting a PSA are to ensure that the following items are not impacted due to a physical security breach:

  1. Financial Stability (this refers to the financial stability of the entity in the event of a physical breach which would disrupt operations - based on a physical security risk, what would the financial risk be to the entity?)
  2. Safety of the entity’s personnel, facilities and the public
  3. Safety of the public due to the compromise of the entity’s IT and OT systems and/or facilities
  4. Operational Continuity
  5. Public Image and Perception

Benefits of a PSA

While many benefits of performing a PSA are self-evident, such as identification of major security vulnerabilities (i.e., unlocked doors, unsecured perimeters, lack of physical access controls, ineffective lighting, CCTV and guarding processes), other findings can reveal blind spots that may be woven into the culture of an organization.

Case Study: While performing an on-site physical penetration testing of office locations, it was discovered that the staff lacked training and awareness on confronting strangers in their office. Their natural sense of hospitality overrode the need for diligence with unknown intruders. By having a third-party, vendor neutral consultant perform the PSA, the client benefited from seeing their organization from an antagonist’s vantage point and quickly provided the appropriate training.

Many companies install the latest security systems but fail to follow up with training and policies on physical security essentials. While many regulatory bodies request proof or certification of training for employees on security policies, there is also a trend where firms are requesting attestation from suppliers, vendors and other organizations of their security practices in order to contain risk in the firm’s supply chain. A PSA will help demonstrate due diligence and rigor, along with the desire to futureproof the security ‘investment’ by incorporating a maintenance and replacement program.

Physical Security Plan and Solutions

The results of the physical security assessment drive the solutions to mitigate the risk identified, potential threats, and vulnerabilities. Just as with cyber security, the solutions focus on the three key elements for a successful program which are “People,” “Governance & Process,” and “Technology,” as depicted below:

Fig 1: Key Elements of Physical Security

The concept of physical security can be likened to a three-legged stool, where the three legs represent People, Governance & Process, and Technology. Each leg is crucial for maintaining the stability and security of the overall system. If any of these three items fails (see Fig 1), it could destabilize the entire stool and potentially affect physical security, which could result in a financial impact, reputation impact, potential non-compliance, and safety risks of the personnel (including employees, contractors, service providers, vendors, consultants, and the public). Just as a stool cannot stand without all three legs, physical security cannot be fully achieved without the proper integration and alignment of its three key elements.

Physical Security Monitoring

The need for proactive surveillance for critical utility assets in the critical infrastructure sector (Electric, Water/Wastewater and Gas) cannot be overstated. Electricity is considered the most essential of all critical infrastructure, and the utility assets are the cornerstone of a utility to ensuring the safe, dependable, and reliable supply of electricity.

The same applies to the other critical infrastructures, the compromise of the Water/Wastewater and Gas distribution systems can have a major impact on the safety of the public, the entity’s personnel, and facilities.

An intrusion into the facility by unauthorized, typically untrained, or unqualified people is unacceptable for several reasons. A single intrusion can seriously impair the flow of electricity, water and gas, cost tens of thousands of dollars in repairs, cause loss of life or limb, significantly impact the ability of the facility to function, take long lead times to repair or replace equipment, and ultimately tarnish the brand and reputation of the facility owner.

Once physical security controls and video surveillance has been implemented, it is important to ensure that there is active monitoring and not just passive recording for just after-the-fact forensic.

Proactive protection covers four areas of defense-in-depth (see Fig 2): Deter, Detect, Active Deterrence and Defend:

Deter: The obvious presence of cameras, strategically located site lighting, and signage that announces monitoring, acts as an initial deterrent to potential thieves.
Detect: If someone ignores the defense systems in place and intrudes on the facility, AI monitoring recognizes the threat and notifies a security agent.
Active Deterrence: The security operator activates additional deterrents, using security lights and verbal warnings delivered via loudspeakers to make it clear to intruders that they are being monitored in real time.
Defend: In the final line of defense, security operator dispatch police or utility crews to the scene.
