Security is more than just having locks on doors or cameras in corners. In today’s digitally connected environments, your Access Control System is the foundation of your physical security strategy. But just because you have a system in place does not automatically mean it is secure. From outdated hardware to weak software configurations, there are several ways your access control can be compromised.

At XTEN-AV, we help AV professionals, system integrators, and facility managers build secure, future-ready systems. Whether your facility is a corporate office, a school, a hospital, or a co-working space, understanding how secure your Access Control System is will help you identify vulnerabilities and improve overall safety.

In this blog, we will break down key security risks, essential protective measures, and how to evaluate the strength of your current access control setup.

What Makes an Access Control System Secure?

A secure Access Control System should do more than unlock doors. It must protect against unauthorized access, safeguard user credentials, record access attempts, and integrate seamlessly with other security layers such as video surveillance and alarms.

Core pillars of access control security include:

• Credential security

• Hardware protection

• Network safety

• Software integrity

• System scalability and flexibility

If any of these elements are weak or outdated, your entire facility could be at risk.

1. Are You Using Encrypted Credentials?

Many organizations still use legacy systems with low-security credentials like magnetic stripe cards or proximity cards, which can be easily cloned or duplicated.

Check if your system uses:

• Smart cards with encryption

• RFID with secure data formats

• Mobile credentials with multi-factor authentication

• Biometric credentials such as fingerprints or facial recognition

Switching to encrypted or multi-layered credentials can drastically improve the security of your Access Control System.

2. Is Your Access Control Software Up to Date?

Outdated software is one of the easiest ways for attackers to find vulnerabilities.

You should ensure:

• Regular updates and patches from the vendor

• Removal of unused user accounts or permissions

• Strong admin passwords and role-based access controls

• Logging and reporting of all access attempts

Cloud-based systems often receive updates automatically, but on-premise setups may require manual attention. Make software maintenance a routine task.

3. How Well Is Your System Network Protected?

Most modern access systems rely on network communication between devices, controllers, and servers. This creates potential risks if the network is not secured.

To protect your network:

• Use firewalls to restrict external access

• Segment access control traffic from public networks

• Employ end-to-end encryption for data transmission

• Regularly audit network devices and IP addresses

Your Access Control System should never share a network with unsecured public Wi-Fi or guest systems.

4. Do You Have Physical Security for System Components?

Even the best digital protections can be bypassed if hardware is left vulnerable.

Check the following:

• Is the control panel housed in a locked, secure area?

• Are readers and card scanners tamper-proof?

• Are door strikes and magnetic locks installed correctly?

• Are backup batteries and power supplies safely enclosed?

Physical protection of your system’s components prevents unauthorized tampering or forced entry.

5. Can You Track and Respond to Security Events?

A secure system is not just about prevention but also detection and response.

Your system should be able to:

• Log all access events with time stamps and user info

• Alert administrators of denied access attempts

• Integrate with video surveillance for visual verification

• Trigger lockdowns or alarms during emergencies

Having real-time visibility into who accessed which door and when allows you to act quickly if something goes wrong.

6. Are Access Permissions Updated Regularly?

One of the most overlooked areas in access security is user management.

Ask yourself:

• Are access rights removed immediately when someone leaves the organization?

• Do temporary workers or guests have time-restricted access?

• Are users only given access to the areas they need?

Failure to manage access permissions can result in unauthorized entry by former employees, contractors, or even intruders with found or stolen credentials.

7. Are You Using Multi-Factor Authentication Where Possible?

Multi-factor authentication (MFA) requires users to present two or more verification methods before access is granted.

Examples include:

• A smart card plus a PIN

• A mobile app plus fingerprint scan

• A biometric scan plus face recognition

MFA adds another layer of security and is especially valuable for sensitive areas like server rooms or executive offices.

8. Is Your System Scalable and Future-Proof?

Security is a moving target. As threats evolve, your system needs to adapt.

Consider the following questions:

• Can your system handle additional doors or user profiles?

• Does it support integration with modern surveillance and IoT devices?

• Can it be managed remotely via cloud-based platforms?

If your system is outdated or inflexible, now is the time to plan for an upgrade.

9. Are You Training Your Staff or Tenants on Security Practices?

Even the most secure system can be compromised by user behavior.

Training topics should include:

• Not sharing credentials or keycards

• Reporting suspicious activity or tailgating

• Understanding emergency procedures

• Recognizing phishing or spoofing attempts for digital credentials

Building a security-first culture can reduce both intentional and unintentional access control breaches.

10. Do You Conduct Regular Audits and Tests?

The only way to know if your system is truly secure is to test it.

Audit routines should include:

• Reviewing access logs for unusual activity

• Testing lock and reader responses

• Inspecting the physical condition of all components

• Verifying software and firmware versions

• Simulating unauthorized access attempts to test response

Regular testing identifies weaknesses before attackers do.

Conclusion

So, how secure is your Access Control System? If you are unsure about even one of the points above, it may be time for a full evaluation. A weak or outdated access control setup not only compromises physical security but also exposes your organization to compliance and liability risks.

At XTEN-AV, we help AV and security professionals design reliable, secure, and intelligent access control systems that meet the demands of today’s environments. With the right technology and strategy, your doors will remain secure, your data protected, and your people safe.

Security is not just about locking the door. It is about making sure only the right people can open it—every time.
