How Are PoE Enterprise Networks Becoming More Secure?

How Are PoE Enterprise Networks Becoming More Secure?

Security is of paramount concern for any commercial office IT network. Storing and transmitting vast amounts of sensitive data, including financial, personal, and proprietary information, requires robust protection against data breaches and cyber threats. Power-over-Ethernet (PoE) enterprise networks can help facilitate this level of cybersecurity by supporting the next level of innovation in commercial office space infrastructure, including:

  • Smarter architecture. 
  • Advanced security measures.
  • AI-driven threat detection.
  • Stricter regulatory compliance.
  • Hardware innovation.

With these technologies, supported by PoE enterprise networks, modern commercial property owners can protect the businesses and employees working within their buildings to stay secure despite increasingly sophisticated cyberattacks. 

Improved Architecture Zero Trust Architecture (ZTA)

Zero Trust Architecture (ZTA) operates on the principle of “never trust, always verify.” With ZTA in place, every user, device, and application on the network is continuously authenticated and authorized, whether outside or inside the corporate firewall.

Even within the network perimeter, ZTA restricts access based on parameters such as user identity, behavior, and device posture. Micro-segmentation of networks limits attackers’ lateral movement even if one part of the network is successfully breached. Minimum access and continuous monitoring further mitigate attacks.

Identity First Security

Multifactor authentication (MFA) has become the norm for modern networks. Deeply intertwined with a Zero Trust security model, Identity First protection makes identity verification and ongoing authentication the primary control mechanism. Identity governance, including user behavior analytics, can be integrated into corporate identity management platforms. This technology supersedes older, traditional models where anything inside a network is inherently trustworthy. 

Enhanced Endpoint Security

Hybrid work requires commercial offices to enforce strict device compliance. Laptops, mobile devices, and IoT tools can be effectively monitored with endpoint detection and response solutions, especially when enhanced with cloud-based analytics.

Software-defined wide area networks (SD-WAN) combine networking with security for offices housing multiple branches of employees. SD-WAN helps enforce consistent security policies across in-office and remote employees via cloud-based Secure Access Service Edge (SASE) models.  

Encrypted Traffic Inspection

Most internet traffic is now encrypted by default. As data travels through a network, encryption converts it into an unreadable, coded format only authorized users can decrypt via decryption keys. To detect hidden threats, firewalls and proxies include TLS inspection capabilities. 

Network Access Control

To grant access dynamically, Network Access Control (NAC) systems include contextual data such as location, time, and behavior. Only authorized, authenticated, and compliant users and devices can access network resources. Device attestation and posture-checking tighten BYOD (bring-your-own-device) policies. 

AI-Powered Threat Detection

By leveraging AI and Machine Learning (ML) algorithms, systems can analyze vast amounts of data to identify patterns that might indicate a cyberattack is underway and take immediate actions, like isolating compromised devices without constant human monitoring. Analysis of historical data can predict potential vulnerabilities and risks before an exploit occurs.

AI/ML can spot unusual behaviors on the network, like abnormal login and data access attempt patterns. Increasingly sophisticated phishing emails and new strains of malware that traditional methods might miss can be detected and blocked. Playing a key role in Security Orchestration, Automation, and Response (SOAR) platforms, AI/ML automates many routine security tasks and accelerates incident response. 

Compliance-Driven Enhancements

Beyond the practical benefits, companies should be further motivated to embrace hardened security and greater risk oversight thanks to new regulations such as:

  • SEC cybersecurity rules (US): The U.S. Securities and Exchange Commission requires that registrants disclose any cybersecurity incidents under their watch and file an annual report on steps to increase their cybersecurity risk management strategies and governance.
  • NIS2 (EU): Enhances the security of networks within the EU by requiring operators to implement security measures and report incidents to the appropriate authorities. 
  • State-level data laws: Most states in the US have their own data security laws atop those mandated by the SEC. 

Compliance audits demand continuous and comprehensive security assessments.

Advanced Hardware and Supply Chain Hardening

More secure IoT/smart building devices like smart lighting, security systems, and HVAC now come equipped with better firmware protections, identity-based access, and auto-updating features. Taking specific steps, like properly vetting vendors, can harden supply chains. Before installing new devices, identify potential vulnerabilities by consulting the enclosed hardware and software bills of materials (SBOMs).

What are PoE enterprise networks?

An enterprise network can be considered the central nervous system of a commercial operation. It typically involves connecting numerous devices, multiple users, and diverse applications across various locations. PoE enterprise networks incorporate PoE technology to deliver electrical power and data connectivity to devices over standard Ethernet cables.

PoE offers:

  • Scalability: PoE technology grows as organizations expand or change.
  • Simplified Infrastructure: PoE makes extra wiring and complicated installations unnecessary.
  • Centralized Power Management: Devices can be remotely monitored, managed, and reset for operational efficiency.
  • Rapid Deployment: With PoE infrastructure, IT experts can deploy devices much faster, essentially making them plug-and-play.
  • Improved Safety: PoE uses low-voltage DC power, safer in areas exposed to temperature fluctuations or accessible to the public.
  • Enhanced Security: Advanced security measures protect sensitive data and prevent unauthorized access.

Because they do not require adding additional wiring or professional installation, a PoE enterprise network is an excellent way for building owners can save costs.  

A Feature-Rich PoE Switch for Commercial Office Security

The VX-GPU2626 (V2) from Versa Technology is a managed Universal PoE switch with a full suite of L2 capabilities. Comprehensive security features like IP source guard and Access Control List (ACL) guard networks from unauthorized access.

Easy to install, configure, and troubleshoot through the built-in device management system (DMS), the switch offers:

  • 24 10/100/1000TX PoE ports.
  • 2 combo GbE RJ45/SFP ports.
  • 60 watts per port.
  • 2000 watts PoE power budget.
  • 0 to 40ºC (32º to 104ºF) operating temperature.

The VX-GPU2626 delivers lower total cost of ownership and better cost performance for Enterprise networks via fiber or copper connections. Universal Power over Ethernet (UPoE) design extends the IEEE PoE+ standard to double the power per port from 30 to 60 watts. The unit is ideal for powering IP phones, IP cameras, high-power wireless APs, LED lighting, and IP devices with power-saving features like power scheduling and PoE configuration.Contact Versa Technology for more information.
