The role of physical security services in protecting sensitive information

The average cost of a data breach is nearly $5 million (USD) per incident. However, in industries like healthcare, utilities, and critical infrastructure, the costs — and the risks — can be much higher.

Even with strong cybersecurity measures in place, it is essential to not overlook the importance of physical security in protecting sensitive information. Physical and cybersecurity are interdependent components of a comprehensive data breach prevention strategy. For instance, effective physical security systems help ensure that unauthorized individuals are unable to access critical areas such as server rooms, data centers, and other restricted environments.

In today’s post we’ll explore common physical and cybersecurity threats, and share six best practices to help you strengthen your organization’s overall security posture.

Common threats to physical and cyber security

One of the most significant contributors to security breaches is human error. Employees who lack awareness or training in security best practices are often the weakest link in your organization’s defense. From propping doors open or failing to manage access consistently, simple mistakes can create big problems.

Social engineering tactics, such as phishing, exploit human vulnerabilities and can grant attackers access to login credentials, which can be used to infiltrate networks or override physical security settings.

Outdated software, unpatched systems, and unsecured networks can serve as entry points for cybercriminals. Unprotected endpoints such as laptops, mobile devices, and IoT devices increase the attack surface, making it easier for malicious actors to infiltrate your network and security systems.

Physical security vulnerabilities, including inadequate access controls and weak perimeter defenses, can lead to unauthorized access to critical areas. For example, employees or those wishing harm may exploit a lapse in server room security to compromise sensitive data.

An integrated security approach to protect sensitive information

A layered security approach that combines physical security services with cybersecurity best practices provides the best defense against modern threats. Organizations must implement comprehensive security strategies, including vulnerability audits and risk assessments.

Vulnerability audits and risk assessments

Conducting regular security assessments will enable you to identify and address potential weaknesses in your physical security to safeguard sensitive information. Routine audits highlight physical security vulnerabilities that need to be addressed, helping you to mitigate threats proactively.

Cybersecurity assessments should test access controls and any software used in physical security processes.

Physical access controls

Audits should also focus heavily on access control. Controlling who has access to sensitive areas is an essential part of a robust physical security solution. Making sure you have adequate protections and permissions prevents unauthorized individuals from making changes to your software.

Physical and cybersecurity controls can include advanced features, such as:

• Keycards and role-based access - Implementing role-based access restrictions limits employee access to the areas needed to do their jobs.  While employees can easily access authorized areas, they are prevented from entering secure areas where sensitive data is stored.
• Biometric authentication - Fingerprint and facial recognition can also ensure that only authorized personnel enter restricted zones, adding another layer of protection.
• Mobile phones - Apps on smartphones can also be used for physical access control security credentials with configurable entry rights.

Video surveillance

Implementing video surveillance with real-time monitoring is essential for areas that house sensitive information. This capability allows security personnel to actively oversee high-risk zones and respond to potential threats as they occur.

Advanced AI-enabled cameras can further enhance security by detecting suspicious activity and automatically alerting teams to potential risks. Additionally, recorded footage provides critical evidence for investigating security incidents or conducting internal reviews.

Manned guarding

Having trained security personnel on-site adds an additional layer of protection against unauthorized access. Security guards ensure that only authorized personnel enter secure areas, preventing potential data breaches.

The presence of security personnel also discourages malicious actors from attempting access, acting as an additional deterrent.

Best practices for physical security services to protect sensitive information

Implementing the following six best practices goes a long way toward strengthening your organization’s security.

1. Conduct regular risk assessments

Organizations should conduct regular risk assessments to identify vulnerabilities in their physical security infrastructure. These assessments should evaluate access control systems, surveillance equipment, security systems and software, and perimeter security.

By consistently monitoring security protocols, you can adapt to emerging threats and ensure your physical security measures remain effective.

2. Implement comprehensive employee training programs

Staff should be educated on how to recognize social engineering tactics like impersonation and phishing, which could lead to unauthorized access. By fostering a culture of security awareness, you can reduce the risk of human error and enhance your overall defense mechanisms.

3. Strengthen collaboration between physical security and IT teams

To create a seamless security strategy, organizations should encourage close collaboration between physical security teams and IT departments. These teams must work together to detect and mitigate threats that span both digital and physical domains.

A unified approach ensures that physical security incidents, such as unauthorized access attempts, are analyzed in conjunction with cybersecurity data, allowing for a more comprehensive response. By sharing intelligence and coordinating response efforts, both teams can mitigate threats more effectively.

4. Utilize multi-layered access control measures

An effective access control strategy should incorporate multiple layers of security. This can include biometric authentication, keycard access, or manual verification processes to ensure that only authorized personnel can enter sensitive areas.

Redundancy in security significantly reduces the likelihood of unauthorized access. This applies to both physical and cybersecurity measures, such as using multi-factor authentication to avoid changes to security settings.

5. Have an incident response plan in place

You should also have a comprehensive plan in place that outlines what to do when an incident occurs. Your incident response plan should include:

• Defined roles and responsibilities for employees
• Communication and reporting protocols
• Emergency procedures, such as lockdown protocols
• Threat assessment tools to quickly gauge impact
• Containment and eradication procedures
• Reporting and documentation requirements

Time is critical in physical security breaches, so you want to have all the information you need prepared ahead of time.
