Automation can help you streamline network management in your enterprise by reducing human error, speeding up processes, and facilitating NetDevOps. Hyperautomation takes things a step further by attempting to remove all human intervention from IT and business workflows.

This blog will define hyperautomation and automation, compare both concepts, and discuss the challenges and best practices for implementation.

Hyperautomation vs Automation: How are they different?

What is automation?

Automation is the removal of manual intervention and workloads within IT departments. You can use automation for development, QA testing, systems administration, and security, but we’re focusing on network automation in this blog.

The goal of network automation is to solve specific challenges. For example, configuring and deploying new network devices is a tedious, time-consuming process. A configuration mistake could cause downtime or even a security breach, so reducing human error is critical to preventing these issues. Plus, there are logistical challenges involved in deploying new devices to remote data centers, branch offices, and edge locations: do you pre-stage the device and risk someone intercepting it in transit and gaining access to your enterprise network? Or do you spend the time and money to fly engineers out to remote sites to configure and install the equipment in person? One way automation solves this problem is through what’s known as zero touch provisioning (ZTP), which allows devices to automatically download and install their configurations over the network without human intervention.

ZTP solves one particular problem for you—new device configurations—and that’s all. It isn’t concerned with any other workloads or processes. You can integrate ZTP with other automated tools and systems, or you could use it by itself, and in either case, it’s still considered automation.

What is hyperautomation?

Hyperautomation, on the other hand, seeks to automate all (or most) IT and business processes. That means automation is essentially a subset of hyperautomation – you need as much automation as possible if you want to achieve true hyperautomation.

Hyperautomation requires automating every workflow and process involved in achieving a certain outcome, including simple tasks like rebooting devices and complex workflows like updating servers. That also means every part of a workflow sequence of events needs to be automated—both the success path and the failure path—otherwise, you won’t achieve full hyperautomation.

Let’s consider the above example of a new network device that needs to be deployed to a remote site. If everything goes according to plan, the device—let’s say a wireless access point—automatically configures itself via ZTP, and no human intervention is required. However, if something goes wrong and the configuration can’t execute successfully, the ZTP process stops, and a human engineer must jump in to troubleshoot the problem.

Hyperautomation requires that you anticipate and programmatically account for any potential failures in an automated workflow. What happens if the TFTP server is offline or unavailable? What if there’s no existing configuration file for the specific model of AP you’re deploying? There should always be a next step available for your automated workflow, even if the previous step has failed. The hyperautomation failure path may eventually lead to a human being (ideally with automatic alerts and notifications), but only after exhausting all automated troubleshooting and error correction possibilities.

Hyperautomation can only be achieved through the use of an automation orchestration platform. These platforms give you a big-picture overview of your hyperautomation efforts so you can store, deploy, and manage all your automated workflows in one place. Orchestration also involves automating your automation—another essential component of hyperautomation—which means your platform automatically runs, monitors, and troubleshoots your automated processes. This is accomplished through technology like AI (artificial intelligence), SDN (software-defined networking), and ZTP mentioned above.

Hyperautomation challenges

Automation and hyperautomation are a little easier to achieve in development and systems administration, but unfortunately, network automation has been slow to catch up.

The biggest network hyperautomation challenge is automating legacy systems designed without automation in mind. If these legacy systems are left out of your automation efforts, it’s impossible to achieve hyperautomation. You could replace all your legacy devices with newer systems that support automation out of the box, but that’s an expensive and time-consuming endeavor that could delay or even prevent your hyperautomation efforts from getting off the ground. A better solution is to find an orchestration platform that can interact with both legacy and modern systems.

One challenge to network hyperautomation is vendor lock-in. Modern enterprise networks are often composed of several solutions from different vendors. That makes it challenging to find automation solutions compatible with every single piece of your infrastructure—like storage, security, etc. For hyperautomation, you need your orchestration platform to dig its hooks into every device, workflow, and process in your network infrastructure, which means it needs to be truly vendor neutral.

Another difficulty is maintaining the hardware that makes up your network infrastructure so that your hyperautomation can work efficiently. This is especially challenging for highly distributed enterprise networks with critical infrastructure in many remote locations. To ensure successful hyperautomation in such an architecture, you need a robust environmental monitoring system that can detect issues in remote data centers and branches. The data collected by this monitoring system should provide feedback to the orchestration platform so problems like high humidity or physical tampering can be automatically acted upon and remediated before they hamper other automated workflows.

Though network hyperautomation is challenging, there is a solution that can help you overcome all these hurdles.

How to Choose Secure Out-of-Band Management

shutterstock_1638957298

Out-of-band access gives you an alternative path to manage your critical remote infrastructure at data centers, branch offices, and other distributed locations. However, that management link creates an additional point of entry for malicious actors to breach and even control your network.

That’s why secure out-of-band management solutions must include features like onboard firewalls and zero trust security to keep your network protected while still giving you remote management access. Let’s take a look at the many secure out-of-band management features and why they’re crucial to the security of your enterprise network.

What is out-of-band management?

Out-of-band (OOB) management separates your production network from your management plane, giving you a dedicated remote connection to your infrastructure even during an outage. The OOB network is completely independent of your primary network and is specifically  dedicated to infrastructure management. That means you can administer your critical remote infrastructure without affecting production network performance. You can also remotely troubleshoot and recover from outages, preventing expensive and time-consuming truck rolls.

OOB management typically uses serial console servers at data centers and remote offices to create an alternative path to critical network infrastructure. For example, using a DSL modem or 4G cellular connection to provide uninterrupted access. Secure out-of-band management solutions offer additional functionality like zero touch provisioning and onboard firewalls to ensure malicious actors cannot use your OOB access.

How to choose secure out-of-band management

Since an out-of-band management solution provides access to an entire network plane that’s dedicated to managing your critical infrastructure, you must keep this power out of the wrong hands. Here are five secure out-of-band management features to help you defend your network.

1. Third-party security integrations

The most secure OOB platforms are vendor-neutral and support integrations with third-party security solutions. That means you can extend the security functionality of your OOB device to take advantage of technology like next-generation firewalls (NGFW) or security service edge (SSE). A vendor-neutral out-of-band solution lets you keep up to date with security best practices and innovations without needing to replace your OOB hardware. It also conveniently creates a fully integrated platform to manage all your branch network security solutions.

A truly secure out-of-band management solution will address security threats from all angles, including provisioning, patching, intrusion detection, and advanced authentication. In addition, a secure OOB platform should support vendor-neutral integrations with third-party security solutions so you can extend your defensive capabilities.

2. Secure zero touch provisioning

One of the challenges of deploying and managing remote infrastructure is configuring and installing new network devices. Unless you have IT staff at each location to install your bare-metal devices, you’re usually left with two options:

  • Pay for your engineers to travel on-site to deploy the new systems. This option is expensive and time-consuming since it can take full day’s of work or weeks.
  • Pre-stage your devices at the home base and then ship them preconfigured. This option is a huge security risk. If a pre-configured OOB serial console is intercepted in transit, an attacker could potentially use it to access your management network.

Zero touch provisioning (ZTP) solves these problems by automatically deploying new device configurations over the WAN. You can ship a bare-metal OOB appliance to your remote site, have a local employee plug it into the power and network, and then the ZTP device will download its configuration from a remote server (such as a TFTP server). However, not all zero touch provisioning solutions are equally secure. Theoretically, a hacker could still intercept your factory-default appliance, use ZTP to download its configuration, and breach your enterprise network.

A secure ZTP solution uses features like encrypted hardware boot sequences to prevent unauthorized users from being able to fully boot up and configure a stolen OOB device. Additional security features like cloud-based provisioning with 2FA (two-factor authentication) also ensure that your network will be protected even if your OOB serial console falls into the wrong hands.

3. Up-to-date OS and fast patches

One of the most straightforward security features in an OOB solution is a frequently patched and up-to-date OS (operating system) kernel. This is important because hackers often look for OS vulnerabilities to exploit. If such a vulnerability is discovered in your OOB device, an attacker could potentially use it to gain administrative control over your entire network.

You should always look for a secure out-of-band management solution with an up-to-date OS kernel and frequent patch releases. Even better, you could get a managed OOB solution that’s updated by the vendor as soon as they become aware of a security vulnerability, so you don’t need to spend the time or manpower to frequently monitor and patch your OOB device’s OS.

4. Onboard firewall features

A secure out-of-band management solution should also have some onboard firewall functionality to further protect your network. An onboard firewall should protect both the OOB network and the primary network by scanning traffic on both connections.

On the OOB connection, the firewall acts as an additional layer of security that prevents malicious actors from gaining access to your management network. An onboard firewall allows you to consolidate your tech stack by reducing the number of separate devices at each remote site from your main network connection.

5. Zero trust security

Zero trust is a network security paradigm that addresses the challenges of protecting distributed enterprise networks from modern, sophisticated cyberattacks. Zero trust security is based on the principle of “never trust, always verify.” Meaning, all network entities—users, devices, applications, etc.—must be verified every time they connect, even if they’re on your internal network. This limits how much damage a compromised device or account can do to your network.

In addition, zero trust security focuses on shrinking your defensive perimeter into a series of smaller micro-perimeters around the critical data, systems, and resources you’re protecting. This enables you to implement highly specific security policies and controls to address the individual vulnerabilities and risks of each network asset.

A secure out-of-band management solution should support zero trust security principles by allowing you to implement advanced authentication methods like SSO (single sign-on) and 2FA. It should allow you to monitor and control devices across network micro-segments. And, assuming your secure OOB solution includes an onboard firewall, you should be able to apply granular security policies and firewall rules to each of your micro-segments to create micro-perimeters even at your network edge.
