Understanding the Basics of Cyber Hardening for Physical Security Systems

Physical security systems have been an important part of our everyday technology for a long time, and they continue to evolve. Traditional security methods have evolved over time into sophisticated digital networks that control access, monitor environments, and protect assets, utilizing advanced technology such as artificial intelligence. However, for these new systems to remain effective, they must be regularly updated. This is where cyber hardening becomes vital, with the goal of fortifying physical security systems against digital threats. 

Throughout this blog post, we will explore the fundamental principles of cyber hardening for physical security systems. This essential concept provides an understanding of how to effectively defend against cyber intrusions, as well as best practices for implementing hardening measures. 

What is Physical Security Hardening?  

Physical security hardening is the process of making systems, networks, and devices more resilient to cyber-attacks and unauthorized access. This includes strengthening communication protocols, authentication methods, and software components to defend against malicious actors. 

The Risks of Missing Proper Cyber Hardening Measures  

The purpose of security systems is to protect your assets and organization. However, without strong cyber-hardening measures, physical security systems become vulnerable to cyber-attacks and can serve as an unprotected entrance for criminals.  

Below are 5 examples of the real consequences of not implementing proper hardening measures: 

  1. Vulnerability to Cyber Attacks - Equipment may be exposed to malware, spyware, denial-of-service (DoS) attacks, or unauthorized access to sensitive data, including intellectual property. 

  2. Physical Threats - Unauthorized individuals gaining physical access to the organization, theft of valuable equipment, and even acts of vandalism and sabotage. 

  3. Regulatory Compliance - Some industries are subject to specific regulations and standards with the intention of protecting people’s privacy, security, and organizational assets. If you and/or your organization do not comply with these regulations, it can result in legal penalties.  

  4. Reputational Damage - Any security incident, particularly those involving physical security, can harm an organization's reputation and undermine the trust of its customers, partners, and stakeholders. In addition, negative publicity can be beneficial for competitors.  

  5. Safety Hazards - In some cases, inadequate security measures can pose a safety risk to employees, visitors, and the general public, interfering with emergency responses or critical industrial processes. 

5 Essential Aspects of Cyber-Hardening  

There are 5 important aspects to consider when implementing cyber-hardening controls on security systems. These 5 aspects include (1) authentication and access control, (2) encryption, (3) patch management, (4) network segmentation, and (5) incident response planning. 

  1. Authentication and Access Control: This aspect serves as the gateway to our assets, so it is critical to implement strong measures. Multi-factor authentication and additional access controls ensure that only authorized personnel have access to sensitive areas or critical systems.  

  2. Encryption: This aspect is critical for data security both in transit and at rest. There are various encryption algorithms for different protocols, but identifying and implementing strong encryption methods is critical for compliance and data security. 

  3. Patch Management: Effective patch management is critical for quickly addressing security vulnerabilities. Regular security updates and patches help mitigate potential exploits, making the system less vulnerable to cyber-attacks. 

  4. Network Segmentation: This aspect improves protection by separating security systems from other networks. This strategy helps to prevent intruders from lateral movement and limits the impact of security. This can be used to isolate the security system network and other networks within the organization. 

  5. Incident Response Planning: Developing an incident response plan entails creating strong response protocols. This plan should be tested regularly and updated as needed to ensure that cyber threats are addressed effectively while minimizing their impact on physical security systems. 

3 Best Practices to Consider Implementing   

3 additional best practices that can be implemented as part of the hardening process include (1) effective vendor management, (2) comprehensive employee awareness programs, and (3) regular security audits. 

  1. Effective Vendor Management: Choosing reputable vendors who prioritize security in their products and services can be extremely beneficial and significantly reduce the risk for your organization without requiring much additional effort "right out of the box". This can be accomplished by evaluating vendor security practices and certifications, ensuring compliance with industry standards. 

  2. Comprehensive Employee Awareness Programs: Another good practice is to provide a comprehensive awareness program for staff and employees. Human error remains one of the most serious vulnerabilities in any security industry, including physical security. Organizations that provide security training empower employees to recognize and respond to potential threats, giving them the skills they need to protect sensitive information and infrastructure. 

  3. Regular Security Audits: Conducting regular security audits is an important component of effective cyber hardening in physical security. This enables organizations to identify vulnerabilities and weaknesses in their systems and take appropriate action. To accomplish this, it is critical to employ tools, methodologies, and security professionals who can assess the effectiveness of existing security controls and identify areas for improvement. 

Cyber Hardening is a Critical Safeguarding Task 

Implementing cyber hardening in physical security systems is an important task that any organization must prioritize in order to protect its critical assets and infrastructure. With the constant evolution of cyber threats, adaptation is required to ensure ongoing protection and resilience against new vulnerabilities. Physical security cyber hardening can have a significant impact on your organization's survival, therefore ensure you take the proper precautions and measures needed to ensure your cyber hardening is up to speed.
