It goes without saying that data breaches are expensive. According to IBM’s 2025 Cost of a Data Breach Report, the average cost of a single breach hit $4.4 million last year. Organizations are pouring resources into firewalls, endpoint protection, and zero-trust frameworks. Yet one attack surface keeps slipping through the cracks: audiovisual (AV) systems.
Conference room displays. Video conferencing codecs. Digital signage. Room scheduling panels. These devices connect to the same networks as your most sensitive data, yet they’re rarely treated with the same security rigor as a laptop or a server. Most were designed for performance, not protection, and that gap is exactly what cybercriminals exploit.
Why Is AV Security So Important Right Now?
It’s easy to understand why AV systems have become such a cybersecurity blind spot. For most of their history, they were standalone, hardware-centric setups—a projector, a cable, a remote. Disconnected from networks, they posed little risk.
That changed as AV and IT converged. Today’s AV environments are deeply networked, cloud-enabled, and software-dependent. A video conferencing system might authenticate against an enterprise directory, stream content over IP, and pull software updates from vendor servers—all while sitting on the same network as financial records and customer data.
As the transformation happened, the security practices around it failed to keep up. Many AV integrators specialize in performance and user experience, not cybersecurity. Devices often ship with default credentials. Firmware goes unpatched for months or years. Logs are either disabled or stored locally in volatile memory where they’re never reviewed. The result is a growing attack surface with few of the controls that IT teams take for granted elsewhere.
How Do You Build an AV Security Framework?
The good news is there are many best practices that can be rapidly assembled and deployed to build a cohesive and comprehensive AV security framework. Securing AV systems isn’t fundamentally different from securing any networked device, but it does require AV-specific knowledge to do it right. Here are the core areas that matter most.
Network Segmentation & VLAN Configuration
One of the most important AV security measures is network segmentation. AV devices should be placed on isolated VLANs (Virtual Local Area Networks) to prevent lateral movement by threat actors within the broader IT environment. These VLANs should be separated by firewalls with rules that allow only essential traffic to and from AV endpoints.
For example, an AV control VLAN might allow outbound connections to a management server but deny internet access entirely. This reduces exposure to threats like malware propagation or unauthorized remote access.
Access Control & Authentication Policies
AV devices, particularly control processors, DSPs, video conferencing codecs, and room scheduling panels, often ship with default credentials or no authentication at all. Develop and enforce strict access control policies for all your devices, including:
- Mandatory change of default usernames and passwords
- Implementation of centralized authentication, such as LDAP, SAML, or RADIUS integration
- Role-based access control (RBAC) to ensure only authorized personnel can access or configure devices
- Session timeouts and account lockouts after repeated failed login attempts
Firmware & Software Management
AV endpoints often run proprietary or embedded operating systems, which are rarely patched or updated unless proactively managed. A solid firmware and software management policy should cover four areas: an asset inventory that tracks device models and firmware versions, a process for monitoring vendor security patches, a scheduled upgrade cadence with rollback options, and a test environment for validating updates before they reach production.
Encrypted Communications
All IP-based AV control and streaming traffic should be encrypted using secure protocols such as HTTPS, SSH, and SRTP (Secure Real-Time Transport Protocol). Make sure that web interfaces for AV control systems are served over HTTPS with valid TLS certificates; remote access (if allowed) is tunneled through a secure VPN with multi-factor authentication (MFA); and any inter-device communication, especially in conferencing systems, uses encrypted transport wherever supported.
Monitoring, Logging & Threat Detection
Most AV systems either do not generate logs by default or store them locally in volatile memory. A strong AV security posture requires integration with centralized logging and Security Information and Event Management (SIEM) platforms. Protocol should include:
- Enabling and configuring syslog forwarding from AV control systems, switches, and firewalls
- Monitoring logs for suspicious activity such as repeated login attempts or unexpected configuration changes
- Implementing intrusion detection/prevention systems (IDS/IPS) at network boundaries to monitor AV traffic patterns
Device Hardening & Configuration Baselines
Each AV device should be hardened according to manufacturer’s guidelines and best practices before it goes live. That means disabling unused ports and protocols (Telnet, FTP, SNMPv1), removing unnecessary services and applications, enabling secure boot features where available, and establishing configuration baselines.
Hardening isn’t a one-time task. Firmware updates, device resets, and unauthorized changes can all shift a device away from its AV security baseline. Regular audits catch that before it becomes a problem.
Incident Response & Disaster Recovery Integration
AV security should not be treated in isolation; it should be well integrated you’re your organization’s broader incident response and business continuity plans. Predefined response procedures for AV-related breaches, regular backups of AV configurations and control code, and AV-specific scenarios in tabletop exercises all help ensure that when something goes wrong, the response is fast and coordinated.
What Operations & Maintenance Best Practices Should You Follow to Maximize AV Security?
Once your AV security systems are deployed, the work of AV security has only just begun. People change, vendors release patches, new vulnerabilities surface, and devices drift from their baselines.
AV security operations and maintenance (O&M) is what closes the gap between a secure deployment and a secure system months and years later. Here’s what a structured AV cybersecurity O&M program should cover.
Patch & Firmware Management
Track and apply security patches and firmware updates on all your AV equipment, making sure that your patch schedule aligns with vendor release cycles and vulnerability disclosures. As always, test firmware updates in staging environments before deployment if possible.
Continuous Monitoring & Health Checks
Monitor device and system logs for signs of compromise or anomalies. Validate the operational status of AV cybersecurity controls, such as firewall rules, IDS alerts, and user access logs. And review and analyze event logs for unauthorized access or misconfigurations.
Access Control Review
Perform quarterly reviews of user accounts and access privileges, rotate administrative passwords, and update credential vaults. Be sure to revoke access for any inactive or terminated users.
Configuration Drift & Hardening Validation
Regularly scan your systems for configuration drift from secure baselines. Re-harden devices as needed to adjust for updates, resets, and unauthorized changes. Make sure your encryption, password policies, and port settings remain enforced.
Threat Intelligence & Vulnerability Response
It’s a good idea to subscribe to your AV vendor and AV-specific cybersecurity threat feeds to keep tabs on new and emerging threats. As CVEs (Common Vulnerabilities and Exposures) and emerging threats are identified, proactively coordinate a rapid remediation action plan for your organization.
Documentation & Reporting
Maintain updated inventories, network diagrams, and data flow maps of you AV systems. Document patch logs, access reviews, and incident response activities. And treat your AV security reporting like you would handle any other cybersecurity reporting to your leadership team. For many organizations, this means monthly or quarterly reports summarizing system health, updates, and detected threats.
Security Testing & Drills
Establish a scheduled cadence for your to AV security testing, which should include annual penetration testing and vulnerability assessments, periodic phishing simulations and physical security walkthroughs of your AV spaces, and incident response tabletop exercises with your IT, AV, and leadership teams.
Sample AV Security O&M Schedule
| Task | Frequency |
|---|---|
| Patch & Firmware Review | Monthly |
| Log & Alert Review | Weekly |
| Access Control Audit | Quarterly |
| Configuration Baseline Verification | Quarterly |
| Vulnerability Scanning | Bi-Annually |
| Full System Cybersecurity Assessment | Annually |
Why Cybersecurity Expertise Alone Is Not Enough
General IT security knowledge isn’t always enough. AV environments involve proprietary protocols, embedded operating systems, and device categories that most IT teams don’t encounter in other contexts. A video conferencing codec or a digital signage player behaves differently from a Windows workstation—and securing it requires familiarity with that difference.
Organizations that treat AV security as an IT afterthought tend to end up with configurations that look secure on paper but have gaps in practice. Specialized providers who understand both the AV and IT sides of the equation can implement standards-based controls that actually hold up under scrutiny.
Building AV Security Into Your Broader Strategy
AV systems represent a real and growing attack surface. The convergence of AV and IT isn’t slowing down—if anything, the expansion of hybrid work, cloud-managed AV platforms, and unified communications has accelerated it. The organizations that get ahead of this risk are the ones that treat AV security as a first-class concern, not an afterthought.
The steps aren’t mysterious. What they require is deliberate attention and the right expertise. If your organization hasn’t assessed the cybersecurity posture of its AV environment recently, that’s the logical first step—map what you have, evaluate how it’s configured, and build a roadmap for closing the gaps.
