Introduction: The New Security Battleground Inside Network Hardware
For years, enterprise cybersecurity strategies have focused heavily on protecting users, endpoints, and application workloads. Frameworks like Zero Trust Architecture and initiatives around supply chain security have transformed how organizations defend their digital environments. Identity verification, least-privileged access, and micro-segmentation have become industry standards.
Yet one critical layer of infrastructure has often been treated as inherently trustworthy: the network hardware itself. Switches, routers, and the control-plane software that powers them have historically relied on hardening practices and periodic patching rather than real-time security enforcement.
That assumption is increasingly dangerous. Modern networking devices are no longer simple hardware appliances. They run sophisticated software that manages routing, automation, APIs, telemetry, and segmentation. In effect, they function as highly privileged computing systems embedded directly inside the network fabric.
Attackers have noticed.
Security agencies and researchers have repeatedly warned that threat actors actively target vulnerabilities in network infrastructure devices. When attackers gain a foothold inside the network control plane, the potential damage expands far beyond a single compromised server or endpoint.
To address this growing risk, Cisco has introduced a new approach called Cisco LiveProtect, designed to bring real-time runtime security directly into network switches themselves.
The Growing Threat to Network Infrastructure
The security conversation is evolving. Historically, enterprises focused their defensive efforts on endpoints, servers, and cloud workloads while assuming that the network backbone remained secure.
However, today’s switches and routers operate more like specialized computers than fixed hardware devices. They run complex operating systems responsible for:
Routing traffic across networks
Managing segmentation policies
Exposing APIs for automation
Collecting telemetry and monitoring data
Providing remote administration tools
This transformation has made network infrastructure a high-value target.
Security analysts increasingly warn that attackers exploit vulnerabilities in networking devices to establish persistent access inside enterprise environments. Once a switch or router becomes compromised, the attacker effectively gains privileged visibility and control over the traffic flowing through the network.
In such a scenario, the network itself becomes the attacker’s foothold. Instead of compromising individual machines one by one, adversaries can monitor, manipulate, or redirect traffic across multiple systems simultaneously.
The blast radius grows dramatically.
The Patch Delay Problem Security Teams Face
One of the biggest challenges in securing network infrastructure is the speed of patch deployment.
Unlike software running on servers or cloud workloads, updating core switching infrastructure requires careful coordination. Network teams must test updates, schedule maintenance windows, and ensure that changes do not disrupt production systems.
As a result, patch timelines for networking devices often stretch into weeks rather than days.
At the same time, attackers are becoming faster.
Threat intelligence reports show that vulnerabilities in networking devices are frequently exploited shortly after public disclosure. In some cases, attackers begin scanning the internet for vulnerable devices within hours.
When remediation may take 30 days or more, organizations are left with a dangerous exposure window.
During that period, attackers can exploit known vulnerabilities while defenders are still preparing patches.
For security leaders and CISOs, this creates a critical challenge. Patching alone cannot close the gap between vulnerability discovery and real-world exploitation.
Embedding Runtime Security Directly Into Switches
To address this problem, Cisco introduced Cisco LiveProtect, a runtime security capability embedded directly into the operating systems of modern switches.
Rather than relying solely on external monitoring tools or delayed response workflows, LiveProtect allows security policies to run inside the kernel of the switch control plane.
The technology is built on eBPF and Tetragon developed by Cisco’s Isovalent engineering team.
These technologies enable security monitoring and enforcement to operate at the exact point where system processes execute.
Because the protection runs directly within the kernel, it has full visibility into system behavior and can react immediately to suspicious activity.
This dramatically reduces the delay between detection and response.
Even more importantly, eBPF programs can be deployed dynamically. That means security protections can be rolled out across devices without interrupting network traffic or requiring service downtime.
Technology Already Proven at Hyperscale
The underlying technology behind LiveProtect is not experimental.
eBPF has already become a cornerstone of modern cloud infrastructure. Major technology companies including Google, Meta, and Netflix rely heavily on eBPF to power networking, observability, and security functions across massive distributed systems.
The technology has been widely studied and documented by organizations like the Linux Foundation.
One of the reasons hyperscalers trust eBPF is its safety model. Programs are verified before execution to ensure they cannot crash the system or create instability.
Once validated, they compile into efficient native instructions that run with extremely low overhead.
This combination of safety, performance, and deep system visibility makes eBPF particularly well suited for security enforcement inside critical infrastructure.
In many ways, hyperscale cloud providers have already proven the model at enormous scale.
Cisco is now bringing that same concept into enterprise networking hardware.
Extending Kernel-Level Security Into Enterprise Switches
Cisco LiveProtect represents a significant shift in how network infrastructure is secured.
By integrating eBPF-based enforcement directly into switching hardware, Cisco is effectively extending modern workload-style runtime security to the network control plane itself.
The technology is initially being deployed within Cisco Nexus Switches, which are widely used in enterprise and data-center environments.
This means the same type of kernel-level behavioral monitoring used to protect cloud workloads can now protect the networking infrastructure those workloads depend on.
Instead of waiting for patch cycles to eliminate vulnerabilities, LiveProtect can enforce behavioral policies immediately, limiting what compromised processes are able to do.
In practice, this reduces the attack surface during the critical vulnerability window.
Securing the Foundation of Modern Digital Infrastructure
Every digital system ultimately relies on its underlying network.
Applications depend on it. Identity systems rely on it. Security controls operate through it.
If attackers compromise the network foundation itself, every other layer becomes vulnerable.
Cisco LiveProtect attempts to address this fundamental risk by bringing real-time security enforcement directly into the network infrastructure.
Rather than treating networking devices as passive infrastructure, the technology treats them as active computing systems requiring the same runtime protections used for servers and applications.
It marks a shift toward a future where infrastructure security operates continuously, not just during patch cycles.
What Undercode Say:
Network Infrastructure Is the Next Cybersecurity Frontline
The cybersecurity industry has spent the last decade protecting workloads, endpoints, and identities. But the network itself has often been overlooked as a security boundary.
That assumption is changing rapidly.
Modern networks are software-defined, programmable, and deeply integrated with automation frameworks. This makes them incredibly powerful but also introduces new attack surfaces.
Attackers know that compromising a network device can be far more valuable than compromising a single server.
From a strategic perspective, controlling network infrastructure allows adversaries to:
Monitor traffic across the organization
Perform man-in-the-middle attacks
Inject malicious packets or reroute data
Hide lateral movement across systems
This is why state-sponsored threat actors increasingly target routers and switches during advanced intrusion campaigns.
The concept behind Cisco LiveProtect reflects a broader industry shift toward runtime infrastructure protection.
Traditional security tools rely on log analysis, network monitoring, or endpoint detection after suspicious activity has already occurred.
Runtime security operates differently. It enforces policies directly where processes execute, preventing malicious behavior before it spreads.
eBPF has become one of the most important technologies enabling this approach.
Originally developed for networking performance monitoring inside the Linux kernel, eBPF has evolved into a powerful platform for observability, networking, and security enforcement.
Its ability to dynamically inject programs into kernel execution paths without requiring system restarts makes it ideal for protecting always-on infrastructure like network switches.
What makes Cisco’s approach particularly interesting is the extension of hyperscaler techniques into enterprise networking hardware.
Companies like Google and Meta already run enormous infrastructures powered by eBPF-based networking stacks.
By embedding similar capabilities into enterprise switches, Cisco is effectively bringing hyperscale security models into corporate data centers.
However, this evolution also highlights a deeper trend in cybersecurity.
The boundaries between infrastructure, operating systems, and security platforms are disappearing.
Networking devices are no longer simple packet-forwarding machines. They are programmable systems running complex software stacks.
Protecting them requires the same mindset used to protect cloud workloads.
In the future, runtime protection inside infrastructure components may become the standard rather than the exception.
Just as endpoint detection became mandatory for laptops and servers, runtime security inside network hardware may soon be expected across enterprise environments.
If that happens, Cisco’s LiveProtect could represent one of the early steps toward a new security baseline.
