Cyber Essentials Plus Checklist for AV Deployments

Audiovisual (AV) systems are no longer standalone solutions. They form part of a converged networked infrastructure, making cyber security an essential consideration for AV deployments.

This article explains Electrosonic's measures to maximize networked AV security by complying with Cyber Essentials Plus and describes the scope and benefits of Remote Technology Support Services.

Cyber Essentials Plus Checklist for AV Deployments

Today’s audiovisual solutions are highly integrated with other networked systems. These include:

  • IT systems
  • Building management systems
  • Environmental management systems
  • Access control systems
  • Security and surveillance systems

AV integrators, therefore, recognize the importance of network security when deploying or upgrading AV systems. Every deployment must be 'cyber ready' to protect the AV systems and the client's core network against cyber threats.

Ensuring network security reduces the risk of cyber breaches. These can damage clients' systems and result in the loss of confidential data. Cyber breaches can also impact a client's reputation or lead to legal or financial penalties.


Cyber Essentials Plus Checklist for AV Deployments


Electrosonic is committed to minimizing cyber security risk and is committed to ensuring ongoing compliance with the recognized legislation, including:

  • Cyber Essentials Plus in the UK
  • NIST Guidelines - Cyber Security Framework 2.0 in the US
  • Federal Information Processing Standards (FIPS) in the US
  • Other regional or client-specific cyber security frameworks

Cyber Essentials Plus and Cyber Security Frameworks help organizations guard against the most common cyber threats. Certification also demonstrates a commitment to cyber security and provides a clear picture of an organizations cyber security level.


Experiential Technology for Corporate Spaces


Cyber Essentials Plus checklist for AV deployments 

Electrosonic's engineering and commissioning teams understand network security essentials. They have deep knowledge and experience of working in highly secure networked environments. The teams integrate new and existing AV hardware and software with centralized control systems.

Engineers integrate AV systems with other client systems on a single converged network infrastructure where possible. This ensures consistent security standards throughout the organization. Sometimes, they create bespoke software solutions to improve AV security management.

The teams engineer, install and program these complex AV systems in line with Cyber Essentials Plus requirements. They collaborate with clients' IT and security teams to assess threats and implement measures to reduce vulnerabilities. The teams advise clients on AV hardware risks and mitigations and recommend measures covering:

  • Audio, video and control systems
  • AV-related LANs or WANs
  • Local connections and endpoints
  • Connectivity for cloud access

Electrosonic recommends using strong passwords on all AV endpoints and encryption on all networked AV data. These measures are essential for secure collaboration in hybrid working environments.

Encryption protocols include:

  • AES- 256 (Advanced Encryption Standard)
  • 802.1X
  • TLS (Transport Layer Security)
  • SSH (Secure Shell Protocol)
  • HTTPS (Hypertext Transfer Protocol Secure)
  • MFA (Multi-Factor Authentication)
  • Directory-based permissions


Applying these measures reduces vulnerabilities and helps clients ensure compliance with regulations. While strong security is essential at the deployment stage, it is equally important to maintain protection when AV systems are operational. Secure networked AV simplifies that by providing a safe remote support and management platform.

A custom remote support solution  

In a recent project, Electrosonic managed AV systems and security for a professional services organization with eight locations.

Utilizing a centralized control system, our service team can remotely access the client's networks and meeting room systems. The team can access Crestron virtual software in the client's data center. The Crestron software manages all the AV hardware across all sites. This solution provides the flexibility and ability to monitor and control all meeting room hardware from a single point.

Electrosonic developed custom software to simplify management, which is loaded into a processor. The software communicates with any display or AV device that needs to be monitored. It manages device telemetry, its IP address and associated passwords and exports it to its digital twin in the cloud. 

In addition, the software is scalable, which improves consistency and reliability and results in less troubleshooting.

Scalability is important because it simplifies the task of adding and programming new devices. The software also enables consistent standards of monitoring across the client's entire estate. That could have been a problem because the client's installation included eight generations of AV hardware. Different devices would have required various levels of support.

The custom software simplifies updating and maintaining the various generations of existing hardware. It also provides a seamless maintenance solution with a consistent look and feel across the estate.

Maintaining compliance with Cyber Security Plus 

Security is an integral element of this remote support solution. Electrosonic engineers ensure stringent password protection on every device. They lock down laptops so that client staff cannot install additional software. Electrosonic's engineers' laptops are also set up with data encryption and limited administrator privileges.

Additionally, our client service teams use a dedicated encrypted password management system to access the client's remote sites. The remote connection system, developed in collaboration with the client, supports single sign-on or multi-factor authentication incorporating unique passwords.

As the client has achieved Cyber Security Plus accreditation, maintaining the most robust security standards is critical to the remote support function. To maximize the security posture, the service team monitors hardware diagnostics and installs the latest firmware and security updates.

Electrosonic's Remote Technology Support Services solution can potentially manage all aspects of AV hardware security in the future. The service team would be able to establish procedures to identify security threats and take remedial action to mitigate their impact.

Future Cyber Safeguards 

The demand for remote AV technical support is on the rise as more organizations embrace hybrid working models. The integration of AI-powered solutions promises to significantly enhance these capabilities by automating troubleshooting tasks, supporting predictive maintenance, and providing expert recommendations.

Furthermore, advancements in remote support security are crucial in mitigating the growing risk of cyber-attacks on converged networked AV systems. Enhanced multi-factor authentication, stronger encryption protocols, increased user awareness, and advanced threat detection solutions will play vital roles in safeguarding these systems.

Together, these technological and security advancements supported by Remote Technology Support Services will ensure a more secure infrastructure, reducing the risk of cyber threats such as hacking, malware, phishing and other forms of attacks.
