Edge computing allows organizations to process data close to where it’s generated, such as in retail stores, industrial sites, and smart cities, with the goal of improving operational efficiency and reducing latency. However, edge computing requires a platform that can support the necessary software, management, and networking infrastructure. Let’s explore the 2024 Gartner Market Guide for Edge Computing, which highlights the drivers of edge computing and offers guidance for organizations considering edge strategies.

What is an Edge Computing Platform (ECP)?

Edge computing moves data processing close to where it’s generated. For bank branches, manufacturing plants, hospitals, and others, edge computing delivers benefits like reduced latency, faster response times, and lower bandwidth costs. An Edge Computing Platform (ECP) provides the foundation of infrastructure, management, and cloud integration that enable edge computing. The goal of having an ECP is to allow many edge locations to be efficiently operated and scaled with minimal, if any, human touch or physical infrastructure changes.

Before we describe ECPs in detail, it’s important to first understand why edge computing is becoming increasingly critical to IT and what challenges arise as a result.

What’s Driving Edge Computing, and What Are the Challenges?

Here are the five drivers of edge computing described in Gartner’s report, along with the challenges that arise from each:

1. Edge Diversity

Every industry has its unique edge computing requirements. For example, manufacturing often needs low-latency processing to ensure real-time control over production, while retail might focus on real-time data insights to deliver hyper-personalized customer experiences.

Challenge: Edge computing solutions are usually deployed to address an immediate need, without taking into account the potential for future changes. This makes it difficult to adapt to diverse and evolving use cases.

2. Ongoing Digital Transformation

Gartner predicts that by 2029, 30% of enterprises will rely on edge computing. Digital transformation is catalyzing its adoption, while use cases will continue to evolve based on emerging technologies and business strategies.

Challenge: This rapid transformation means environments will continue to become more complex as edge computing evolves. This complexity makes it difficult to integrate, manage, and secure the various solutions required for edge computing.

3. Data Growth

The amount of data generated at the edge is increasing exponentially due to digitalization. Initially, this data was often underutilized (referred to as the “dark edge”), but businesses are now shifting towards a more connected and intelligent edge, where data is processed and acted upon in real time.

Challenge: Enormous volumes of data make it difficult to efficiently manage data flows and support real-time processing without overwhelming the network or infrastructure.

4. Business-Led Requirements

Automation, predictive maintenance, and hyper-personalized experiences are key business drivers pushing the adoption of edge solutions across industries.

Challenge: Meeting business requirements poses challenges in terms of ensuring scalability, interoperability, and adaptability.

5. Technology Focus

Emerging technologies such as AI/ML are increasingly deployed at the edge for low-latency processing, which is particularly useful in manufacturing, defense, and other sectors that require real-time analytics and autonomous systems.

Challenge: AI and ML make it difficult for organizations to determine how to strike a balance between computing power and infrastructure costs, without sacrificing security.

What Features Do Edge Computing Platforms Need to Have?

To address these challenges, here’s a brief look at three core features that ECPs need to have according to Gartner’s Market Guide:

  1. Edge Software Infrastructure: Support for edge-native workloads and infrastructure, including containers and VMs. The platform must be secure by design.
  2. Edge Management and Orchestration: Centralized management for the full software stack, including orchestration for app onboarding, fleet deployments, data storage, and regular updates/rollbacks.
  3. Cloud Integration and Networking: Seamless connection between edge and cloud to ensure smooth data flow and scalability, with support for upstream and downstream networking.

Zombie Servers: The Hidden Energy Drainers in Data Centers

by | Oct 30, 2024 | Data Center Management, Data Center Resilience, Improve Network Security, Minimize Impact of Disruptions, Monitoring & Reporting, Network Automation, Out of Band Management, Power Management, Remote Network Management

Zombies in the data center
As enterprises adopt AI, cloud computing, and data analytics, one thing lurks in the shadows of their data centers: zombie servers. These inactive or severely underutilized servers take a big bite out of operations, drawing power and resources without contributing meaningful work. Research from the Uptime Institute indicates that as much as 30% of servers may be idle at any given time, suggesting enterprises could save millions each year by identifying and eliminating these “zombies.”

The Cost of Zombie Servers

When it comes to cost, zombie servers can devour more than their fair share. Each idle server can consume approximately 200 to 400 watts per hour, resulting in annual power costs of $400 to $600 per server. In large data centers housing thousands of servers, wasted energy expenses can easily scale into the millions. Currently, U.S. data centers account for over 4% of the nation’s total electricity consumption, a figure projected to rise to 6% by 2026 due to growing demands from AI and cloud computing applications.

How ZPE Systems’ Nodegrid Fights Zombie Servers

Out-of-band management (OOBM) solutions, like ZPE Systems’ Nodegrid, provide an effective way to monitor, manage, and optimize data center infrastructure, even when the primary network is down. When combined with ServerTech Intelligent PDUs, data center admins can remote-in to identify and address zombie servers, so they can ensure their operations run at peak efficiency.

Key Features of Nodegrid’s Out-of-Band Management for Zombie Server Management

  • 24/7 Monitoring and Real-Time Insights: Nodegrid allows IT teams to continuously monitor server performance, making it easy to detect underutilized or idle servers. Real-time metrics show server activity, power usage, and health, so teams can pinpoint servers that may need to be repurposed or removed.
  • Detailed Power Usage Data: The combined Nodegrid and ServerTech solution provides comprehensive energy usage data, so teams can see inefficiencies and where power is consumed most. This is essential for high-density data centers, where wasting even a little bit of power adds up to substantial costs. These insights help data center operators pinpoint zombie servers, reducing energy costs and freeing up space.
  • Enhanced Automation and Management Control: With automation features, Nodegrid simplifies the complex task of managing server lifecycles. For instance, automated alerts can notify teams when a server reaches a specific threshold of low utilization, enabling quicker action to reassign or shut down the server.
  • Increased Security and Resilience: Nodegrid enhances security by providing direct access to infrastructure via isolated management. Teams can access critical systems even during network failures, to ensure servers remain compliant, functional, and secure.

Benefits of Removing Zombie Servers

AI and other resource-intensive applications mean data centers need to be as efficient as possible. Zombie servers are not just an energy problem; they impact a data center’s ability to scale and meet demand for high-performance computing. Here are some benefits of removing or repurposing zombie servers:

  • Energy Efficiency: Data centers can significantly lower energy costs and reduce environmental impact by shutting down idle servers.
  • Cost Savings: Operating more efficiently by removing zombie servers can lead to substantial annual savings, freeing up resources for necessary expansions.
  • Optimized AI-Ready Infrastructure: Freeing up resources allows data centers to repurpose space and energy toward servers that can support AI and other high-density applications.

American Water Cyberattack: Another Wake-Up Call for Critical Infrastructure

by | Oct 18, 2024 | Application Hosting, Data Center Management, Data Center Resilience, Failover Connectivity, Improve Network Security, Micro-segmentation, Minimize Impact of Disruptions, Monitoring & Reporting, Network Automation, Out of Band Management, Power Management, Remote Network Management, Simplify Branch Infrastructure, Vendor Neutral Platform, Zero Trust Security

Industrial water treatment plant with water
The October 2024 cyberattack on American Water, one of the largest water and wastewater utility companies in the U.S., signals yet another wake-up call for critical infrastructure security. Because millions of people rely on this critical service for safe drinking water and sanitation, this attack highlights why it’s so important to address cyber vulnerabilities.

Let’s trace the timeline of the attack, how it likely started, and the best practice architecture that could have mitigated or prevented the American Water cyberattack.

Timeline of the October 2024 American Water Cyberattack

  • Initial Intrusion (October 5, 2024)
    The attack on American Water was first detected in early October, when cybersecurity monitoring tools flagged suspicious activity within the company’s IT systems. Employees reported an unusual system slowdown, and automated alerts indicated possible unauthorized access.
  • Rapid Escalation (October 6-7, 2024)
    Within 24 hours of detection, the attackers had moved deeper into the company’s IT environment. In response, American Water initiated emergency protocols, including isolating key systems to prevent further damage. To contain the breach, critical operational technology (OT) systems — responsible for managing water treatment and distribution — were temporarily shut down
  • Public Notification and Response (October 8, 2024)
    American Water notified federal authorities, including the Cybersecurity and Infrastructure Security Agency (CISA), state regulators, and the public. The company reassured customers that water quality had not been compromised, but certain automated operations had been affected, leading to temporary disruptions in water distribution.
  • Ongoing Recovery (October 2024 – Present)
    As the investigation continued, third-party cybersecurity firms were brought in to assess the extent of the breach and assist in recovery. Manual operations were implemented in areas where automated systems were impacted. While the threat was contained, the company faced a lengthy process of system restoration and reconfiguration.

Impact of the Attack

The impact of the American Water cyberattack appears minimal. A class-action lawsuit was recently filed seeking $5-million in damages on behalf of affected customers, but this is the typical fallout that results from a breach. American Water did not shut down any treatment plants, and although they were forced to temporarily shut down their customer portal, pause billing, and revert to some manual processes, there were no water contamination or public health risks that came out of the attack. Per American Water’s FAQ page, it seems business is nearly back to normal.

However, this shouldn’t diminish the need for utilities providers to shore-up their defenses and ensure resilience of their IT architectures. The Oldsmar, Florida incident is an example of how an error or breach can change water treatment chemistry (in this case, adding too much lye to the water supply) and poison a population. There have also been many attempts by U.S. adversaries in which attackers were able to change water chemistry or disrupt automated operations.

Government agencies like the EPA have been warning that attacks on water treatment utilities are increasing. Lawmakers are also calling for inspections of IT systems, such as to ensure best practices are being followed for managing passwords and keeping remote access from Internet exposure, and considering civil and criminal penalties for those who don’t comply.

How the Attack Likely Happened

The American Water cyberattack is still under investigation. Specifics of how it occurred haven’t been released, but several likely scenarios have emerged based on trends in similar attacks:

  • Phishing or Social Engineering:
    Employees may have unknowingly opened a malicious email attachment or clicked a harmful link, allowing attackers access to the internal network, similar to 2023’s Ragnar Locker attacks. Water utilities and other public services often have large workforces, which makes them susceptible to phishing campaigns.
  • Ransomware:
    There are indications that ransomware may have encrypted key files and systems, similar to what happened during the MGM hack. Ransomware attacks on critical infrastructure have increased in recent years, with attackers locking companies out of their own data and demanding payment to restore access.
  • IT/OT Integration Vulnerabilities:
    Water utilities often rely on a hybrid network where both information technology (IT) systems and operational technology (OT) systems are integrated to monitor and control water purification, distribution, and wastewater management. While this setup improves efficiency, it can also create additional vulnerabilities if the two environments are not properly segregated. Once attackers gain access to the IT network, they can use it as a bridge to reach OT systems, which are typically less secure.
  • Internet-Facing Systems:
    In the past, the Chinese-sponsored hacker group Volt Typhoon took advantage of firewalls that were connected both to the internet and to critical control systems. This approach also takes advantage of a lack of control plane segregation, as hackers can remote-in via internet-facing systems and gain management access to critical systems.

The Solution: Isolated Management Infrastructure (IMI)

As with the global CrowdStrike outage, the most important takeaway from the American Water cyberattack is that organizations need the ability to recover fast. Remote access solutions help with this, but it matters how these solutions are architected and which capabilities they offer.

The traditional approach is to gain remote access via a direct link to the affected systems. The problem with this is that when these systems are breached, encrypted, or offline, it’s impossible to remote-into them. This requires teams to physically connect to and revive systems (as with the CrowdStrike incident), or worse – completely replace their infrastructure, as Merck did during the 2017 NotPetya breach.

Traditional remote management via direct link
Instead, organizations are turning to a best practice architecture that has been used by hyperscalers and large enterprises for years. This solution is called Isolated Management Infrastructure. IMI creates a management network that is connected to but completely independent of production network equipment, an architecture that resembles out-of-band (OOB) management. This gives teams a lifeline to their main IT and OT systems, including servers, switches, sensors, controllers, and other critical assets, even when their main systems are offline.
IMI is a lifeline to production assets

Here’s how IMI and out-of-band management could have helped mitigate the effects of the American Water attack:

  • Enhanced Containment: By isolating the network used for system control and monitoring, OOB management could have ensured that even if the primary network was compromised, attackers would not have been able to access or disable key operational systems. This would have limited the need to shut down OT systems and prevented widespread operational disruption.
  • Faster Recovery: With isolated management infrastructure, administrators would have been able to access critical systems remotely, even during the attack. This capability enables faster diagnosis of the issue and restoration of services without relying on compromised networks. In the case of a ransomware attack, for example, OOB management can help initiate recovery operations from backups, minimizing downtime.
  • Reduced Attack Surface: By creating an independent network with fewer access points and stricter controls, OOB infrastructure reduces the chances of attackers exploiting vulnerabilities. It’s an additional layer of security that complicates attempts to breach sensitive control systems.
IMI with Nodegrid2

30-year cybersecurity expert James Cabe recently published a walkthrough of how to do this. Read his article, What to do if you’re ransomware’d, to see how to deploy the Gartner-recommended Isolated Recovery Environment that lets you fight through an active attack.

Get the Blueprint for Building IMI

The American Water cyberattack is another wake-up call for critical infrastructure providers to rethink their cybersecurity strategies. Isolated Management Infrastructure is the key approach to retaining control during an attack, but requires the robust capabilities of Generation 3 out-of-band to ensure rapid recovery.

Network Virtualization Platforms: Benefits & Best Practices

Simulated network virtualization platforms overlaying physical network infrastructure.

Network virtualization decouples network functions, services, and workflows from the underlying hardware infrastructure and delivers them as software. In the same way that server virtualization makes data centers more scalable and cost-effective, network virtualization helps companies streamline network deployment and management while reducing hardware expenses.

This guide describes several types of network virtualization platforms before discussing the benefits of virtualization and the best practices for improving efficiency, scalability, and ROI.

What do network virtualization platforms do?

There are three forms of network virtualization that are achieved with different types of platforms. These include:

Type of Virtualization Description Examples of Platforms
Virtual Local Area Networking (VLAN) Creates an abstraction layer over physical local networking infrastructure so the company can segment the network into multiple virtual networks without installing additional hardware.

SolarWinds Network Configuration Manager

ManageEngine Network Configuration Manager
Software-Defined Networking (SDN) Decouples network routing and control functions from the actual data packets so that IT teams can deploy and orchestrate workflows across multiple devices and VLANs from one centralized platform.

Meraki

Juniper
Network Functions Virtualization (NFV) Separates network functions like routing, switching, and load balancing from the underlying hardware so teams can deploy them as virtual machines (VMs) and use fewer physical devices.

Red Hat OpenStack

VMware vCloud NFV

While network virtualization is primarily concerned with software, it still requires a physical network infrastructure to serve as the foundation for the abstraction layer (just like server virtualization still requires hardware in the data center or cloud to run hypervisor software). Additionally, the virtualization software itself needs storage or compute resources to run, either on a server/hypervisor or built-in to a networking device like a router or switch. Sometimes, this hardware is also referred to as a network virtualization platform.

The benefits of network virtualization

Virtualizing network services and workflows with VLANs, SDN, and NFVs can help companies:

  • Improve operational efficiency with automation. Network virtualization enables the use of scripts, playbooks, and software to automate workflows and configurations. Network automation boosts productivity so teams can get more work done with fewer resources.
  • Accelerate network deployments and scaling. Legacy deployments involve configuring and installing dedicated boxes for each function. Virtualized network functions and configurations can be deployed in minutes and infinitely copied to get new sites up and running in a fraction of the time.
  • Reduce network infrastructure costs. Decoupling network functions, services, and workflows from the underlying hardware means you can run multiple functions from once device, saving money and space.
  • Strengthen network security. Virtualization makes it easier to micro-segment the network and implement precise, targeted Zero-Trust security controls to protect sensitive and valuable assets.

Network virtualization platform best practices

Following these best practices when selecting and implementing network virtualization platforms can help companies achieve the benefits described above while reducing hassle.

Vendor neutrality

Ensuring that the virtualization software works with the underlying hardware is critical. The struggle is that many organizations use devices from multiple vendors, which makes interoperability a challenge. Rather than using different virtualization platforms for each vendor, or replacing perfectly good devices with ones that are all from the same vendor, it’s much easier and more cost-effective to use virtualization software that interoperates with any networking hardware. This type of software is called ‘vendor neutral.’

To improve efficiency even more, companies can use vendor-neutral networking hardware to host their virtualization software. Doing so eliminates the need for a dedicated server, allowing SDN software and virtualized network functions (VNFs) to run directly from a serial console or router that’s already in use. This significantly consolidates deployments, which saves  money and reduces the amount of space needed This can be a lifesaver in branch offices, retail stores, manufacturing sites, and other locations with limited space.

A diagram showing how multiple VNFs can run on a single vendor-neutral platform.

Virtualizing the WAN

We’ve mostly discussed virtualization in a local networking context, but it can also be extended to the WAN (wide area network). For example, SD-WAN (software-defined wide area networking) streamlines and automates the management of WAN infrastructure and workflows. WAN gateway routing functions can also be virtualized as VNFs that are deployed and controlled independently of the physical WAN gateway, significantly accelerating new branch launches.

Unifying network orchestration

The best way to maximize network management efficiency is to consolidate the orchestration of all virtualization with a single, vendor-neutral platform. For example, the Nodegrid solution from ZPE Systems uses vendor-neutral hardware and software to give networking teams a single platform to host, deploy, monitor, and control all virtualized workflows and devices. Nodegrid streamlines network virtualization with:

  • An open, x86-64bit Linux-based architecture that can run other vendors’ software, VNFs, and even Docker containers to eliminate the need for dedicated virtualization appliances.
  • Multi-functional hardware devices that combine gateway routing, switching, out-of-band serial console management, and more to further consolidate network deployments.
  • Vendor-neutral orchestration software, available in on-premises or cloud form, that provides unified control over both physical and virtual infrastructure across all deployment sites for a convenient management experience.

by | Oct 3, 2024 | Data Center Management, Data Center Resilience, Improve Network Security, Increase Productivity, Minimize Impact of Disruptions, Monitoring & Reporting, Out of Band Management, Power Management, Remote Network Management, Serial Consoles, Zero Touch Provisioning (ZTP), Zero Trust Security

NCSP Back side

Perle offers two console server solutions for out-of-band (OOB) management of data center infrastructure: the IOLAN SCG and the IOLAN SCR. The SCG is available in both fixed and modular form factors, while the SCR comes in four models with different combinations of 56 managed ports, allowing companies to choose the OOB management hardware that best suits their environment. Unfortunately, IOLAN solutions suffer from hardware and software limitations that can curb scalability and limit agility. This guide discusses Perle console server replacement options that enable streamlined growth through automation capabilities and vendor freedom.

Quick Links:

 

Key takeaways

  • Perle IOLAN SCG appliances offer out-of-band console server management for up to 48 devices in a fixed or modular form factor. Perle IOLAN SCR console servers come with four different managed port configurations for added flexibility.
  • Perle console servers offer some automation capabilities, like auto-discovery and zero-touch provisioning, as well as comprehensive firewall functionality. However, their underpowered hardware and closed management software prevent Guest OS hosting or third-party infrastructure automation and orchestration.
  • The Nodegrid platform from ZPE Systems overcomes these limitations with robust CPU, RAM, and storage, as well as vendor-neutral software. It enables data center scalability by providing high-density serial port configurations and supporting 3rd-party automation.
  • Nodegrid can also run networking, security, edge computing, AIOps, and more, consolidating the data center tech stack and improving operational efficiency.

 

Perle IOLAN console server overview

Perle IOLAN SCG console servers provide out-of-band management for up to 48 infrastructure devices. Fixed-form-factor models use copper Ethernet for networking and OOB, while the modular version has options for Wi-Fi, cellular, and dial-up. The modular series also has three expansion bays that support any combination of 16-port RS-232 or USB serial modules.

Perle IOLAN SCR console servers come in four different models with up to 56 managed serial, USB, and Ethernet ports, as well as optional cellular integration.

Click here to compare Perle console server tech specs.

Perle console servers have automatic LLDP (Link Layer Discovery Protocol) discovery and can extend zero-touch provisioning (ZTP) to end-devices. They come with an embedded firewall, OpenVPN and IPSec VPN, and AES encryption. The PerleVIEW cloud-based management software provides centralized monitoring and control of all connected data center infrastructure.

 

Why consider Perle console server alternatives

IOLAN console servers have an underpowered 500 MHz core 32-bit ARM processor, 4GB of flash storage, and 1GB RAM. This hardware may be sufficient for basic infrastructure management workflows and ZTP, but it prevents Guest OS hosting and more advanced automation. The Perle platform also doesn’t integrate with any third-party automation or orchestration solutions.

An inability to fully automate infrastructure management workflows – or to orchestrate those tasks that can be automated – ultimately limits operational efficiency and data center scalability. Consequently, IT teams can’t effectively support the needs of the growing business, adapt to strategy changes, or focus on revenue-driving innovations like artificial intelligence and machine learning (AI/ML).

What’s needed is an open platform that can manage any device, automate any workflow, and work with third-party software to provide a fully integrated infrastructure orchestration experience.

 

Perle console server replacement options from ZPE Systems

Nodegrid is a family of vendor-neutral console server solutions from ZPE Systems. It comes in four models:

  1. The Nodegrid Serial Console Plus (NSCP) is a robust platform offering up to 96 managed serial ports in a 1U rack-mounted form factor for hyperscale data centers and cloud service providers.
  2. The Nodegrid Serial Console S Series provides up to 48 auto-sensing ports to unify management of legacy, modern, and multi-vendor data center environments.
  3. The Nodegrid Net Services Router (NSR) is a modular solution that can be customized with a range of serial, networking, storage, and compute cards to adapt to any use case.
  4. The Nodegrid Serial Console Plus Core Edition (NSCP-CE) is ideal for break-fix deployments while providing more robust security capabilities than comparable solutions.

Nodegrid devices come with Intel x86-32 bit processors, robust (and upgradable) internal storage and RAM options, and a Linux-based Nodegrid OS. The NSCP, S Series, and NSR support Guest OS and Docker containers for third-party applications. That means they can directly host infrastructure automation and orchestration (like Ansible, Puppet, and Chef), security (like Palo Alto’s next-generation firewalls), and much more. Plus, it can extend this automation to legacy and mixed-vendor devices that otherwise wouldn’t support it.

All Nodegrid models can use a wide range of USB environmental monitoring sensors to help remote teams maintain optimal conditions in the data center. Nodegrid hardware protects the control plane with advanced security features like BIOS protection, UEFI Secure Boot, self-encrypted disk (SED), Trusted Platform Module (TPM) 2.0, and a multi-site VPN using IPSec, WireGuard, and OpenSSL protocols. The Nodegrid OS and the ZPE Cloud management software are also Synopsys-validated as achieving industry-leading security.

Our way of life relies on networking infrastructure. Financial transactions, healthcare communications, national security, and everything in between depends on an interconnected web of networking and IT services. As end users, we reap the benefits of instant communications and information at our fingertips. However, this web presents an almost immeasurable amount of supply chain security risk that must be addressed, a job that’s more complex with every solution that enters the ecosystem.

What are the Impacts of Inadequate Supply Chain Security?

Insecure supply chains can lead to widespread and long-lasting consequences. We’ve seen this with backdoor vulnerabilities in firewall hardware, zero-day exploits of popular software products, and many attacks targeting the network’s control plane. The impacts can range from simple data leaks to entire regions being cut off from critical resources due to ransomware attacks.

  • Economic Losses: Cyberattacks on insecure supply chains can lead to significant financial losses, both directly through theft or fraud, and indirectly through damage to reputation and customer trust.
  • National Security Threats: Critical infrastructure such as power grids, transportation systems, and communication networks are prime targets for nation-state actors. Compromised networking hardware or software in these sectors can have severe implications for national security.
  • Global Impact: The interconnected nature of global supply chains means that a vulnerability’s impact can ripple across the world. For example, a compromised component in one region could lead to a cascading failure in networks across multiple countries.

 

What Do Supply Chain Security Vulnerabilities Look Like?

When talking about supply chain security vulnerabilities in networking, this refers to different ways attackers can exploit hardware and software during manufacturing, distribution, and maintenance. These systems are essentially vulnerable during their entire lifespan – from the time their motherboards are installed and code is written, to when they’re in-transit to the customer, to when IT teams are administering regular updates and troubleshooting. But, what do these vulnerabilities look like?

Hardware Vulnerabilities

Networking infrastructure relies on hardware. Illegitimate or counterfeit components can be inserted into the supply chain and make their way into hardware manufacturing processes. This can cause equipment failures, degraded performance, or even deliberate backdoors that allow unauthorized access.

  • Physical Backdoors: Malicious actors can introduce hardware backdoors during the manufacturing process, allowing unauthorized access to the network. These backdoors are difficult to detect and can remain hidden until activated.
  • Long-Term Vulnerabilities: Once a compromised piece of hardware is deployed, it can remain a vulnerability for years, especially in critical infrastructure where hardware lifecycles are longer. Replacing hardware is often costly and logistically challenging.
  • Trust and Reliability: Networking hardware is the first line of defense against cyber threats. Compromised hardware can lead to a loss of trust, not only in the network but also in the organizations responsible for its deployment and maintenance.

 

Software Vulnerabilities

Hardware provides the physical framework, while software controls and manages the flow of data within the network. Malicious code or compromised firmware can be introduced at any point in the software development lifecycle, while some software even ships with zero-day exploits (as with the MOVEit ransomware attack), leading to severe security breaches.

  • Firmware Integrity: Firmware is the software that directly interfaces with hardware. If compromised, it can be used to control or disable hardware components, leading to catastrophic network failures.
  • Regular Updates and Patches: Software vulnerabilities are often discovered post-deployment. Having a robust process for regular updates and patches is crucial in mitigating these risks. However, if the update process itself is compromised, malicious actors can introduce vulnerabilities under the guise of legitimate updates.
  • End-to-End Encryption: Secure software ensures that data transmitted across the network is encrypted, reducing the risk of interception or tampering. This is especially critical in protecting sensitive information from being accessed by unauthorized entities.
  • Third-Party & Open Source Software: Third-party and open source software are used throughout networking infrastructure. When this software is integrated into the ecosystem, it can introduce vulnerabilities and code quality risks, especially if the organization doesn’t have access to the underlying code.

 

Third-Party and Insider Threats

Most companies rely on third-party vendors and suppliers, whether for hardware manufacturing, procurement and logistics, or software development. This adds layers of complexity. If any of these third parties are compromised, the impact can ripple throughout the entire supply chain and contaminate the end products.

Employees or contractors can also put infrastructure integrity at risk. When these employees are trusted with access to sensitive parts of the supply chain, they can compromise overall security, even unintentionally.

How ZPE Systems Shrinks Supply Chain Security Risks

ZPE Systems provides the network management infrastructure that’s essential to managing critical IT for organizations across industries. Although there are many network management infrastructure vendors, most lack a holistic approach to security. Hardware components may be sourced from untrusted manufacturers, and software development may be loosely-controlled and inadequately tested. These parts of the supply chain introduce vulnerabilities that can put customers at much more risk than they realize.

ZPE takes a security-centric approach and offers the industry’s most secure out-of-band management platform. This includes dozens of hardware security features, a Synopsys-validated software development lifecycle, and the most third-party certifications and validations, including FIPS 140-3, SOC 2 Type 2, ISO 27001, and others.
