In the post‑pandemic world, many organizations accelerated their use of cloud services and IoT (internet of things) technologies to support remote and hybrid work. This shift has blurred the line between physical and digital security. When servers, IoT devices, and critical systems are distributed across offices, data centers, and the cloud, a cyber incident can quickly have physical consequences—and a physical breach can expose digital assets. For example, someone gaining unauthorized access to a server room can compromise sensitive data, just as a cyberattack on a cloud‑based access control system can unlock doors remotely. Because of this, it’s increasingly difficult to manage physical and cybersecurity as separate domains with separate tools, teams, and policies. A converged approach: - Aligns protection for both physical and digital assets under one overarching strategy. - Clarifies ownership and responsibilities across security teams. - Supports secure adoption of cloud and IoT technologies without adding unnecessary risk. With a cyberattack occurring roughly every 39 seconds, convergence helps organizations rethink their security posture so they can respond more effectively to modern, blended threats.

Physical security is a critical layer for protecting digital assets such as servers, networking equipment, and workstations that store or process sensitive data. Key practices include: 1. **Cloud‑based access control with mobile credentials** Many organizations are moving to cloud‑managed access control systems that use mobile credentials instead of physical keycards or PIN codes. Employees download an app to receive their access rights, which: - Reduces the risk of lost or cloned cards. - Makes it easier to update or revoke access in real time. - Improves user convenience—especially with Bluetooth readers that allow entry without taking the phone out of a pocket or bag. 2. **Internal door locks and granular permissions** You can lock down sensitive areas—such as server rooms, network closets, and records storage—and apply different permission levels based on role. This supports a zero‑trust mindset on the physical side: you don’t assume everyone in the building is trustworthy or needs access everywhere. 3. **Zero‑trust applied to physical spaces** By treating internal movement like network access, you: - Limit who can reach critical systems. - Reduce the chance of insider threats or accidental exposure. - Gain better visibility into who accessed what, and when. In short, strong physical controls around digital infrastructure are a foundational part of any modern cybersecurity strategy.

When you adopt cloud‑based physical security—such as remotely managed door locks, mobile credentials, and building lockdown controls—you’re effectively putting critical physical functions on the network. That makes cybersecurity essential. There are two main dimensions to address: 1. **Cyber‑hardening the physical security stack** Cloud‑connected access control and video systems can be targeted like any other IT system. If attackers gain control, they could: - Unlock doors or disable locks. - Interfere with lockdown procedures. - Manipulate or delete security logs. To reduce this risk, organizations typically: - Deploy cybersecurity software and controls (firewalls, endpoint protection, secure configurations) around physical security devices and management consoles. - Keep firmware and software updated to close known vulnerabilities. - Enforce strong authentication and role‑based access for administrators. 2. **Merging physical and cybersecurity teams** Because threats now span both domains, keeping physical security and IT security in separate silos makes incident response harder. Many organizations are: - Combining or tightly aligning physical and cyber teams. - Sharing data from access control, video, and IT systems to spot anomalies. - Jointly planning for incidents that could affect both physical and digital assets. Digital enhancements like AI and analytics are also being layered onto physical systems—for example, using AI to monitor video feeds and trigger alerts when suspicious behavior is detected, or analyzing access control data for unusual patterns. This helps teams move from reactive investigation to more proactive threat detection. Overall, securing cloud‑based physical security means treating it as part of your broader cyber program and reimagining team structures, tools, and processes to support a unified, future‑ready security strategy.
