When intrusion alarm systems meet cyber: securing systems beyond the panel
Intrusion alarm systems have become part of the wider, always-connected security landscape. That’s why, argues Rob Janssens, Hikvision Cyber Security Director (EMEA), they must be designed, deployed, and maintained with the same rigor as any other networked infrastructure.
The principle of intrusion alarm systems is very simple. They are networks of integrated physical security devices which are designed to detect unauthorized entry into a building or property. For many decades, their design has been essentially very simple, consisting of just a control panel, a handful of sensors, a keypad, and a monitoring path. These worked because they were also largely isolated from the rest of the world. Even as cyber risks emerged, they tended to be limited, contained, and rarely a central concern.
But eventually that world disappeared. Today, intrusion platforms integrate with video, access control, mobile apps, and cloud services. They have, therefore, become ‘always‑connected’ IT systems that just happen to detect intrusions. The challenge is that every new connection expands the attack surface, introducing risks that extend far beyond the panel itself.
This is where intrusion alarm systems meet cyber. It’s where the task of securing systems end‑to‑end is no longer an option. It’s where, in today’s connected security landscape, intrusion systems must be designed, deployed, and maintained with the same rigor as any other networked infrastructure.
According to physical security market research, over 80% of newly deployed security systems are now connected to networks. This transition to networked security has had profoundly altered the threat landscape. After all, once intrusion platforms integrate IP peripherals, mobile apps and video management systems, they effectively become an always-on network service.
The trouble is that always-on network services are vulnerable to attack. For example, if a disarming mobile app lacks robust encryption or uses default credentials, an attacker can intercept the transmission, gain access, and enter a facility without triggering an alert. That’s why, as intrusion panels evolve into IoT hubs, the most serious exposures tend to appear at the intersection of panel, app, and cloud, rather than at the physical sensor. Key risk areas include unsecured remote access, abstracted cloud/P2P settings, and placing security devices on flat networks. What’s more, precisely because these surfaces are interconnected, a compromise today can propagate far beyond a single site—potentially affecting accounts, credentials, and configurations across multiple installations.
Consequently, maintaining system integrity requires consistent attention to firmware and update mechanisms, identity flows, mobile ecosystems and local network segmentation. Inevitably, therefore, protecting physical security in a world of cyber threats a responsibility that must be shared by both the equipment manufacturers and those that install and maintain their solutions. To prevent security gaps, manufacturers must provide secure default baselines and simplified update tools, while installers must ensure these measures are fully activated and maintained.
If the secure default baselines are weak, cloud services offer limited visibility into infrastructure, firmware updates tend to be painful to apply, and installers inherit a cyber risk they cannot fully control. Similarly, even when secure features are available, if they are not fully implemented by installers — if, for example, encrypted management or role-based access is not properly implemented — the overall resilience of the deployment will be affected.
| Domain of Control | |
| Manufacturers | Device architecture, firmware security, default configurations, cloud APIs, and update mechanisms |
| Installers | Network design, system configuration, deployment practices, updates, and customer guidance |
Manufacturers and installers must share the responsibility to prevent security gaps.
Ultimately, neither party can secure a connected system without the other. This is why clear security documentation, shared incident-response expectations, and realistic hardening guidance are essential tools to turn the concept of shared responsibility into a practical reality.
In modern intrusion systems, then, cybersecurity must coexist with usability. Implementing “Secure-by-Design” principles—which closely align with international frameworks such as ENISA Secure by Design and Default Playbook and the globally recognized ETSI EN 303 645 standard—ensures that remote administration is both highly practical and reliably secure.
As intrusion systems become critical IT assets, installers are right to expect connected platforms to provide a robust, secure-by-default foundation out of the box. At a minimum, this includes:
When securely designed, complexity can be handled under the hood—allowing installers to perform necessary system maintenance efficiently while keeping the customer’s broader IT network fully protected.
Hikvision has increasingly aligned its security platforms to operate safely within modern, demanding IT environments, transforming cybersecurity from a defensive compliance measure into a core product attribute.
In practice, this includes support for:
This forces the creation of unique, strong passwords upon first use, eliminating default credential vulnerabilities.
Industry-standard encryption protocols are used to secure control signals and data streams.
With this feature, the digital signature of firmware must be verified before installation, ensuring that only official, unmodified code runs on the hardware.
Administrative and viewing privileges are restricted to authorized accounts.
All system events, logins, and configuration are automatically recorded to assist in compliance.
These enable administrators to disable unused network ports and services, reducing the device’s discoverable attack surface.
Clear and transparent security advisories and regular firmware patches address new digital threats as they emerge.
Many installations also deploy Hikvision devices on segregated security networks, and only expose necessary services through controlled paths. This allows intrusion and video systems to integrate into broader SOC and IT monitoring workflows without weakening the overall security posture.
Cybersecurity is an ongoing challenge. Failures often emerge years after installation—when systems are forgotten, unsupported, or unpatched. Effective lifecycle security, therefore, requires clear end-of-support timelines, simple update mechanisms, visibility into deployed versions and proactive vulnerability notifications. When lifecycle security is built into tools, portals, and documentation, installers can manage fleets confidently—rather than inheriting a growing technical debt.
Today’s intrusion alarm systems are no longer just alarms, but have evolved to become critical, networked security platforms. When the system meets cyber, success depends on Secure-by-Default design, Informed, accountable installation practices, and transparent collaboration between manufacturers, installers, and users. By treating intrusion equipment as IT-grade systems—designed, deployed, and maintained accordingly—we can, together, protect users, reduce liability, and future-proof installations in an always-on security landscape.
FAQs
When modern intrusion alarm systems connect to IT networks they are subject to cyber threats. Unsecured devices can serve as entry points for threat actors looking to compromise physical security, disable alarms, or pivot to steal sensitive information from the main business network.
"Secure-by-Design" means that a security device is engineered with robust security features from the ground up. This includes having no default passwords, forcing encrypted communication out of the box, and using signed firmware to prevent unauthorized modifications.
Security is a shared responsibility. The manufacturer is responsible for building secure hardware, providing robust firmware, and issuing updates. The installer is responsible for setting up secure network environments, changing passwords, and configuring user permissions according to best practices.
Network segmentation involves isolating the intrusion alarm system on its own separate network rather than placing it on a flat network alongside general IT or IoT devices. This prevents attackers from easily moving laterally to critical security hardware if they breach an insecure device, thereby mitigating both physical and digital security risks.
