How to Secure Your AV over IP Network: Best Practices for IT Teams

As AV and IT continue to converge, AV over IP systems have become the go to choice for distributing audio and video signals across modern networks. They offer flexibility, scalability, and cost savings that traditional AV systems simply cannot match. But with these benefits comes a new set of challenges — especially when it comes to security. Because AV over IP systems rely on the same network infrastructure as your data systems, they can introduce new vulnerabilities if not properly secured. In this blog, we will explore why securing your AV over IP network is so important and share best practices that every IT team should follow.

Why AV over IP Security Matters

AV over IP systems are no longer isolated setups limited to a single room or building. They are often connected to enterprise networks, sometimes with remote access or cloud integration. This means that if your AV system is compromised, it could provide an entry point for attackers to access sensitive data, disrupt operations, or damage your brand.

Common risks include:

• Unauthorized access to AV controls or content.

• Interception of video or audio streams.

• Network congestion or outages caused by malicious activity.

• Spread of malware or ransomware through AV devices.

For these reasons, it is essential to treat your AV over IP systems with the same level of security as your core IT systems.

Best Practices for Securing AV over IP Networks

Here are the key steps your IT team should take to protect AV over IP systems from potential threats.

1. Segment the Network

The first rule of securing AV over IP systems is to segment them from your primary data network. Use VLANs (Virtual Local Area Networks) or separate subnets to isolate AV traffic from sensitive data traffic. This reduces the risk of an AV device becoming a gateway to your entire network.

Network segmentation also helps control bandwidth usage so that AV streams do not interfere with critical business applications.

2. Use Strong Authentication

AV devices and control systems should never rely on default usernames or passwords. These credentials are widely known and are a common entry point for attackers. Make sure all devices are secured with strong, unique passwords and, where possible, enable multi factor authentication for remote access to AV management tools.

3. Keep Firmware and Software Updated

Outdated firmware or software can contain vulnerabilities that hackers exploit. Establish a regular update schedule for all AV over IP devices, including encoders, decoders, switches, and control systems. Subscribe to vendor alerts so you are informed of any new security patches or updates as soon as they are released.

4. Encrypt Your Streams

Where possible, use AV over IP systems that support encryption of video, audio, and control data. Encryption helps protect sensitive content from interception as it travels across the network. While encryption may add some processing overhead, it is a small price to pay for protecting your information.

5. Restrict Physical Access

Physical security is often overlooked in network security planning. Make sure that AV equipment is installed in secure locations, such as locked racks or server rooms. Unauthorized access to hardware can lead to tampering or connection of rogue devices.

6. Monitor Network Traffic

Implement monitoring tools to keep an eye on AV network traffic in real time. Look for unusual patterns, such as unexpected increases in bandwidth usage or connections from unfamiliar IP addresses. Network monitoring can help you detect and respond to potential security incidents quickly before they escalate.

7. Disable Unused Services and Ports

Many AV over IP devices come with extra services or open ports that are not required for your installation. Review the configuration of each device and disable anything that is not essential. This reduces the number of potential attack vectors and simplifies your security management.

8. Control Remote Access

If your AV system needs to be accessed remotely for management or support, make sure this access is tightly controlled. Use VPNs or secure tunneling protocols rather than exposing AV devices directly to the internet. Log all remote access activity and review logs regularly for signs of unauthorized use.

9. Educate Your Team

Security is not just about technology — it is also about people. Provide training for your AV and IT teams so they understand the unique security risks associated with AV over IP systems. Make sure everyone knows how to spot suspicious activity and report it promptly.

10. Develop an Incident Response Plan

No system is completely immune to attacks. Have a plan in place for responding to security incidents involving your AV over IP systems. The plan should include steps for isolating affected devices, restoring services, and communicating with stakeholders. Regularly test and update your plan to ensure it remains effective as your system evolves.

The Role of Vendors and Integrators

Securing AV over IP systems is a shared responsibility. When selecting vendors and integrators, look for partners who take security seriously. Ask about the security features of their products, their update policies, and their experience with secure deployments. A strong partnership can help you build a system that is both powerful and protected.

Final Thoughts

AV over IP systems offer incredible advantages in terms of flexibility, scalability, and performance. But these benefits can only be fully realized if security is treated as a core requirement from the start. By following best practices such as network segmentation, strong authentication, encryption, and regular monitoring, IT teams can protect their AV infrastructure and the larger network it connects to.

Securing AV over IP systems is not a one time task. It requires ongoing attention, collaboration between AV and IT teams, and a commitment to staying ahead of emerging threats. With the right approach, you can enjoy the full potential of AV over IP while keeping your network safe and secure.
