Providing Out-of-Band Connectivity to Mission-Critical IT Resources

7 Security Benefits of Implementing FIPS 140-3 for Out-of-Band Management

ZPE Systems -FIPS 140-3

Out-of-band (OOB) management is essential for maintaining control over critical network infrastructure, especially during outages or cyberattacks. This separate management network enables administrators to remotely access, troubleshoot, and recover production equipment. However, managing network devices outside the main data path also brings unique security challenges, as these channels often carry sensitive control data and system access credentials.

Implementing FIPS 140-3-certified encryption within OOB systems can help organizations secure this vital access path to ensure that management data can’t be intercepted or manipulated by unauthorized actors. Here’s how FIPS 140-3 certification can enhance the security, reliability, and compliance of your out-of-band management.

What is FIPS 140-3 Certification?

FIPS (Federal Information Processing Standard) 140-3 is a high-level security standard developed by the National Institute of Standards and Technology (NIST). It specifies rigorous requirements for cryptographic modules used to protect sensitive data. FIPS 140-3 certification covers everything from data encryption to user authentication and physical security. For out-of-band management, FIPS 140-3 certification ensures that cryptographic components in hardware, software, and firmware meet stringent data security standards.

By implementing FIPS-certified solutions, organizations can ensure their OOB management is resilient against modern cyber threats, protecting both the control channels and the sensitive data they carry. Here are seven security benefits of implementing FIPS 140-3 for out-of-band management.

7 Security Benefits of Implementing FIPS 140-3 for Out-of-Band Management

1. Secure Encryption of Management Traffic

OOB management often involves remote access to routers, switches, servers and other critical devices. FIPS 140-3 certification guarantees that all cryptographic modules used in these systems have been rigorously tested to secure data in transit. Encrypting management traffic is crucial to prevent interception or manipulation by unauthorized users, particularly for tasks such as command execution, configuration updates, and device monitoring.

With FIPS-certified encryption, companies can protect OOB traffic between management devices and network components, so that only authorized administrators have access to sensitive system commands and device settings.

2. Enhanced Authentication and Access Control

OOB management solutions typically support different user roles, each with its own access privileges. FIPS 140-3-certified modules, like ZPE Systems’ Nodegrid, feature multi-factor authentication (MFA) to control who can initiate OOB management sessions. Certified solutions also include secure key management practices that prevent unauthorized access, ensuring that only verified users can control and modify network devices.

These protections mean FIPS-certified solutions help mitigate the risk of unauthorized users accessing high-value assets. This is especially important during ransomware recovery efforts, when teams need to launch a secure, Isolated Recovery Environment to combat an active attack in a compromised environment.

3. Protection Against Tampering and Physical Attacks

Many organizations deploy IT infrastructure in locations where physical device security is lacking. For example, remote colocations, unmonitored drilling sites, or rural health clinics can easily expose network infrastructure to device tampering. FIPS 140-3 certification mandates tamper-evident and tamper-resistant features to protect the cryptographic modules used in OOB systems. OOB solutions like ZPE Systems’ Nodegrid provide robust protection against tampering, with features including:

  • UEFI secure boot: Prevents the execution of unauthorized software during the boot process.
  • TPM 2.0: Ensures secure key generation and storage, so only authorized software can run.
  • Secure erase: Allows for deletion of all data from storage, so no data can be recovered from devices that have been tampered with.

These features prevent unauthorized individuals from physically accessing OOB equipment to intercept or modify management traffic. In remote and edge locations, FIPS-certified cryptographic modules provide robust protection against physical attacks, making it harder for adversaries to compromise OOB management pathways.

4. Compliant and Secure Logging of Access Activities

Because OOB management systems provide access to critical equipment, organizations need transparency into OOB users and their management activities. This means logging and auditing are essential to maintaining security and compliance. FIPS 140-3-certified modules support secure logging of all management activities, creating a clear audit trail of access attempts and security events. These logs are stored securely to prevent unauthorized users from altering or erasing them, providing valuable insights for security monitoring and incident response.

Secure logging is not only critical for monitoring access but also necessary for meeting regulatory compliance. FIPS 140-3 ensures that OOB management systems can satisfy audit requirements, making compliance easier and protecting organizations from potential regulatory penalties.

5. Meeting Regulatory Requirements in Sensitive Environments

Many industries handle sensitive data, especially government, healthcare, and finance. For organizations in these industries, it’s often mandatory to use FIPS-certified cryptographic solutions. FIPS 140-3 certification helps OOB management systems align with federal security regulations and standards like HIPAA and PCI-DSS. By deploying FIPS-certified encryption, organizations can comply with these standards, streamline audits, reduce the risk of regulatory penalties, and reinforce trust with customers.

6. Consistent Security Across Main and OOB Networks

It’s easy for organizations to focus mostly on securing the main network, while overlooking the security protections that they employ on their out-of-band network. FIPS-certified solutions help establish consistent security standards across both paths. This is especially important in protecting against lateral attacks, where hackers infiltrate one network and are then able to jump to the other. In cases where attackers gain access to one segment of the network, matching security protocols across the main and OOB networks prevents them from moving laterally into sensitive management channels.

Using FIPS 140-3-certified encryption across both networks also strengthens the organization’s ability to monitor, manage, and control devices, even when the primary network is under threat.

7. Securing Remote and Edge Devices

For organizations with remote infrastructure, such as telecom and retail, OOB management is critical for managing network devices in distant locations. However, these environments often lack the physical security of centralized data centers, making them vulnerable to tampering. FIPS-certified solutions ensure that all communication with remote OOB devices is encrypted, which protects management data from unauthorized access.

FIPS 140-3 certification also supports the resilience of IoT and edge devices, which often require OOB management for secure monitoring, patching, and configuration.

Terminal Server Alternative for Simple Break/Fix Use Cases

 

The Nodegrid Serial Console Core Edition terminal server alternative.

A terminal server is a device that provides consolidated remote management access to routers, switches, and other network infrastructure in data centers. There are numerous reasons to consider replacing an existing terminal server solution. Many of these devices are old and unpatched, leaving them vulnerable to exploits. Older solutions may not integrate well with newer hardware and software or lack the ability to unify management for all deployed terminal servers across a distributed enterprise network, creating a lot of management complexity and potential human error.

On the other hand, some newer terminal server solutions (also known as serial consoles or console servers) include advanced features or beefed-up hardware that increase both costs and complexity. It’s important to find the right balance between security, functionality, and ease-of-use for your particular use case. This guide compares five terminal server alternatives that are optimized for simple break/fix deployments, giving teams reliable remote management access without unnecessary complications.

Edge Computing Platforms: Insights from Gartner’s 2024 Market Guide

Interlocking cogwheels containing icons of various edge computing examples are displayed in front of racks of servers

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.

Serial Console PDU Management Guide

A close-up photo of power cables in a data center rack.

PDUs (power distribution units) control and optimize how power flows to infrastructure devices like servers, routers, firewalls, and switches. PDUs are difficult to manage remotely, for a couple of reasons. First, many aren’t network-connected, so configuring and updating new devices or fixing problems typically requires tedious, on-site work. Those that do have network connectivity tend to lack automation capabilities and integrations with other tools, so they have to be manually and individually managed.  In modern enterprise environments with complex, distributed networks, managing hundreds of individual power devices one at a time is extremely challenging.

A serial console solves this problem by physically connecting to multiple PDUs and using a dedicated network interface to enable remote PDU management. A next-gen solution like Nodegrid also provides a centralized management platform that teams can use to remotely administer all of the PDUs and other infrastructure devices deployed across the entire distributed network. Plus, Nodegrid has an open architecture that supports third-party power software and automation to streamline infrastructure management and boost operational efficiency.

This guide to serial console PDU management explains everything you need to know to get started with remote power control and automated provisioning using the Nodegrid platform.

Deploying Nodegrid for remote PDU management

Stacked views of the front and back of the Nodegrid Serial Console Plus.

The Nodegrid family from ZPE Systems includes a range of serial consoles and branch routers that are designed for different use cases. They all provide out-of-band management, network failover, and serial console capabilities, but the number and type of interfaces and managed port configurations vary. Critically, all Nodegrid devices can automatically discover power devices from any vendor and provide secure remote access, eliminating the need to manage PDUs on-site.

Nodegrid also has an open architecture that can host or integrate other vendors’ software for PDU management, NetOps automation, SASE security, and more. It gives administrators a single, unified platform to orchestrate both automated and manual workflows for PDUs and other Nodegrid-connected infrastructure at all distributed business sites.

Remotely controlling power for individual outlets

Nodegrid can integrate your PDU so that each managed serial port on the Hive is mapped to a specific outlet. Doing so allows users to power individual outlets off and on from Nodegrid Manager or ZPE Cloud. It also enables a continuous console session to the managed device with BIOS-level control during the reboot cycle.

To map a PDU outlet to a managed serial port from Nodegrid Manager or ZPE Cloud:

1. Click Managed Devices from the top menu bar, and then select the Devices tab.

The Managed Devices :: Devices menu.

2. Click the Commands tab, click ADD, and then select Outlet.

3. Select the applicable PDU, tower, and outlet to map to the specified managed serial port and then click Add. A confirmation message will appear in the window below.

3. Depending on the outlet’s present status, certain options will be available:

  1. Clicking the Outlet On tab will enable an outlet that is powered off.
  2. Clicking the Outlet Off tab will disable an outlet that is powered off.
  3. Clicking Outlet Cycle will power-cycle the outlet, turning it off and then back on again.

Implementing automated PDU provisioning and updates

Nodegrid uses zero-touch provisioning (ZTP) to automatically configure managed devices on boot-up. If your PDU is network-connected and DHCP-enabled, like some ServerTech and Raritan PDUs, Nodegrid’s ZTP can automate configurations and firmware updates.

To implement zero-touch provisioning for PDUs:

  1. Create configuration files tailored to your specific PDU models. These files typically include:
    1. fwupdate.cfg – required for firmware upgrades
    2. config.txt – contains specific device configurations
    3. devices.csv – manages bulk configurations
  2. Upload configuration and firmware files to the Nodegrid Datastore directory, which acts as a root directory for the integrated TFTP/HTTPS server.
  3. Configure Nodegrid’s DHCP server to point to the fwupdate.cfg file on the TFTP/HTTPS server.
  4. Upon their next DHCP renewal, the PDUs will contact Nodegrid’s DHCP server, which will direct them to the fwupdate.cfg file on the TFTP/HTTPS server. The PDUs will fetch these files and perform the necessary configurations or firmware updates. Other configuration options can also be triggered based on vendor-class-identifier settings in the DHCP options.

Nodegrid ZTP includes a magic cookie, a unique identifier stored on the PDU that prevents the repeated execution of the same configuration tasks. If a mismatch between the stored cookie and the new configuration cookie is detected, the device knows to pull fresh configurations, ensuring that updates are only applied when needed.

End of Row vs Top of Rack Deployments

End of Row vs Top of Rack Deployments

The terms end-of-row and top-of-rack refer to two different approaches to data center architecture design. Both approaches have advantages and disadvantages that make them suited to different use cases or teams, with neither being the clear “winner” overall. This blog compares end-of-row vs. top-of-rack deployments based on crucial factors like cost, management complexity, scalability, and resilience to help organizations choose the right approach for their environment.

 

What is an end-of-row (EoR) deployment?

ZPE Graphic Request IR Nov 4
In data center deployments consisting of multiple rows of racks or cabinets, it’s common for teams to consolidate all the networking for each row in one physical location, rather than deploying switches in every single rack. All patch cables for the devices in a particular row are run to the dedicated networking cabinet, which is typically (but not always) at the end of the row. An end-of-row (or EoR) architecture requires fewer switches than a ToR deployment, which helps reduce costs and management complexity while enabling easier scaling.

One of the main drawbacks of this architecture is that the EoR switch is a single point of failure for the entire row. If that switch fails due to a botched update, ransomware attack, or other adverse event, the whole row loses network access. Running cables from each cabinet to the EoR can also get messy very quickly, especially at scale. In the long run, it’s also a less flexible architecture that forces teams to consider an entire row of infrastructure every time they want to change or upgrade networking components.

 

What is a top-of-rack (ToR) deployment?

ZPE Graphic Request IR Nov 4 (1)
In a top-of-rack data center architecture, DC teams install one or more switches in every rack of their deployment; despite the name, the switch doesn’t need to actually be at the very top of the rack. A ToR deployment keeps copper/Ethernet patch cables inside the rack, which helps with cable management. It also eliminates the single-point-of-failure that an EoR switch represents – if one ToR switch goes down for some reason, only the devices within that rack are affected, vs. the entire row. Another major benefit of EoR deployments is that each rack becomes a modular unit that DC teams can modify, upgrade, or scale without necessarily affecting other racks in the row.

On the other hand, a ToR deployment requires more switches than an EoR deployment, which can increase costs and complexity. More switches equate to more power draw, and they add an extra network hop to local traffic that could possibly affect throughput. Each switch must also be monitored, secured, and regularly patched, potentially creating more work for infrastructure teams. As a result, ToR deployments are also more challenging to scale, as each new rack added to the data center requires an additional ToR switch.

Comparing end-of-row vs top-of-rack deployments: Which should you choose?

 

End-of-Row Top-of-Rack
Number of switches One or more per row One or more per rack
Cable management Requires patch cables running along the entire row Keeps patch cables within the rack or cabinet
Cost Fewer switches and lower power draw keeps costs down More switches and higher power draw gets more expensive
Complexity Fewer switches to secure, manage, and troubleshoot More devices to manage
Ease of scaling Can deploy an entire new row with only one networking cabinet Each new rack requires one or more switches
Flexibility Inflexible; networking changes affect entire row Each rack is a modular unit that can be changed without affecting others
Resilience EoR switch is a single point of failure for the entire row One rack’s switch can go down without affecting any other racks

 

Both EoR and ToR architectures have advantages and disadvantages, with neither being the clear-cut winner for every possible use case.

End-of-row deployments are more cost-effective and easier to manage and scale, so they’re often favored by smaller, leaner IT teams or, on the opposite end of the spectrum, very large (or hyperscale) data centers. For example, a large cloud provider might prefer EoR to cut down on the number of switches to purchase, deploy, and manage at their hubs.

Top-of-rack deployments are modular, flexible, and resilient, which makes them a great choice for DevOps teams that need the ability to add or change components at any time without affecting the entire architecture. For example, managed service providers might prefer ToR so they can easily customize or update one customer’s rack without worrying about how the changes will impact others.

How Nodegrid improves resilience for EoR and ToR deployments

Nodegrid serial console switches can be deployed top-of-rack or end-of-row to improve the resilience of either architecture. Nodegrid switches connect to the serial port on data center devices to provide out-of-band (OOB) management, allowing teams to remotely manage and troubleshoot DC equipment even when the primary network is down. They isolate the management interfaces for data center infrastructure, making them inaccessible to malware or malicious actors on the production network. Plus, Nodegrid also provides network failover to keep business-critical services running during adverse events.

Nodegrid serial consoles have an open architecture that can integrate and host other vendors’ software and virtualized network functions. That means a single Nodegrid box could theoretically replace an entire rack of networking hardware, streamlining EoR deployments and making ToR architectures more feasible for lean, budget-strapped IT teams. Plus, Nodegrid switches and all connected devices can be remotely managed from a single, on-premises or cloud-based software platform, significantly reducing management complexity for either deployment.

Zombie Servers: The Hidden Energy Drainers in Data Centers

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.
