What Is Physical Security? What Are The Best Practices?

Cyberattacks are becoming more likely as more businesses are taking their operations online. Data can be stolen, money can be lost, and even a company's image can be hurt by a security breach. Consequently, organizations need to pay attention to both internet security and real-world security. An attacker can get access to confidential information if they gain control of a physical machine or device.

In this piece, we'll learn about physical security and look at the best ways to keep an organization safe. We'll talk about everything one needs to know to keep people, land, and investments safe from physical threats.

What is Physical Security?

Physical security is the most important thing an organization can do to protect its assets. With the right measures in place, organizations can prevent or minimize loss from possible thefts, vandalism, natural disasters, fire, and other damage.

Investing in physical security allows a company to assess threats proactively. Don't wait until a threat happens—take steps now to ensure your organization is safe and secure.

7 Best Practices for Physical Security

1. Access Control

Access control systems help limit who can go in and out of a place and when. Access can be controlled through:

• Key cards
• Fingerprint readers
• Other smart tools

For instance, a company might make all its workers use ID cards to enter the building. Guests receive temporary passes, and all entries/exits are logged digitally.

Data points:

• A 2023 Ponemon Institute study found that the average cost of a data breach caused by compromised credentials was $4.35 million.
• In 2022, over 22 billion records were exposed in global data breaches.

2. Install Video Surveillance

Security cameras are powerful deterrents—especially if intruders know they’re being watched.

Tips:

• Cover entrances/exits (doors, windows, garages, walls)
• Eliminate obstructions and blind spots
• Ensure good lighting for clear footage

Data points:

• Average cost of retail theft in the U.S.: $720.98 per incident

• U.S. businesses lose over $60 billion annually to theft

• Retailers lose an average of 1.44% of inventory to theft

3. Train Employees on Security Best Practices

Employees are a vital part of your security ecosystem. Conduct regular sessions and workshops on:

• Recognizing suspicious activity
• Reporting threats
• Their role in workplace safety

Data points:

• 88% of security incidents involve human error
• 90%+ of successful cyberattacks begin with phishing or social engineering

Training reduces risks and boosts response readiness.

4. Use Perimeter Fencing

A strong physical barrier prevents unauthorized access to sensitive areas.

Tips:

• Choose uncuttable materials
• Add height to discourage climbing
• Use barbed wire on top of chain-link fences

Data point:

• Cargo theft alone costs U.S. businesses $30 billion annually

5. Emergency Response Plans

Having an emergency plan can protect lives and reduce losses. Plans should cover:

• Fire evacuation
• Earthquakes
• Active shooter scenarios
• Natural disasters

Examples:

• Offices display evacuation maps
• Hospitals have mass disaster response protocols

Data point:

• Average property damage caused by a U.S. fire: $251,400

6. Conduct Regular Security Audits

Routine inspections can identify vulnerabilities such as:

• Broken locks
• Dim lighting
• Outdated technology

Options:

• Internal audits
• Third-party security assessments

Data point:

• Regular audits result in 23% fewer breaches and 29% lower breach costs
  (Ponemon Institute, 2022)

7. Cybersecurity

Physical and digital security are now intertwined. Hackers often target physical systems via digital vulnerabilities.

Measures to implement:

• Firewalls
• Intrusion detection systems
• Endpoint security

Examples:

• Banks use digital barriers for unauthorized access
• Hospitals monitor intrusions to protect patient data

Data point:

• Average cost of a ransomware attack in 2023: $4.54 million

8. Partnering with a Security Company

A professional security firm can provide:

• On-site guards and patrol services
• Monitoring tools and alarm systems
• Cybersecurity services
• Security audits and planning

Data point:

The global physical security market is projected to hit $172 billion by 2027, reflecting growing demand for expert services.
