How to stabilise & audit using network configuration and compliance monitoring

What is Network Configuration and Compliance Monitoring

Network Configuration and Compliance Monitoring (or NCCM) is a system that works closely with all devices in a set network, transmitting and receiving data from a wide range of devices to ensure that everything is acting in a compliant manner. In addition to this, NCCM can ensure that your devices are configured correctly, and in the case that they are not, can schedule reconfigurations at a time that is convenient to the user.

Automating NCCM processes is often required because companies often have thousands of devices that cannot be handled manually, making the entire process far simpler and more accurate through automation. One example of an NCCM is Opmantek’s “NMIS”, a network management system designed to offer comprehensive information to network engineers to assist in the diagnosis and resolution of network problems.

Change detection and rectification

When dealing with a device configuration, there are relatively few commands that you need to be aware of to know exactly how it is set up. In theory, by remembering these and applying them to a new device, it should act identically to the previous one. When these configurations change and nobody is informed, however, it can become incredibly difficult to replace the device should it become faulty.

By implementing effective change detection, which discovers any configuration adjustments in a device, you can stay on top of all of your device configurations and replace them with ease. Additionally, you can receive alerts to let you know of every configuration change, and how many times the configuration has changed. This change detection can be used with products such as “opConfig”, which processes and records configuration changes across entire networks.

Device configuration changes

The configuration backups are all saved without restriction, so reverting to any previous configuration is incredibly simple. Your NCCM can keep hourly backups of your configuration settings, allowing you to revert a previous device, router or switch to a previous version when the device was working as intended. This will either resolve the issue or inform you that the issue is likely with the hardware in use (in which case you can simply install new hardware with the successful configuration in place).

Servers and network scanning

In addition to tracking the configuration of your devices, it’s also possible to use an NCCM as a performance tracking tool. By performing automated network management, the system is also taking in significant amounts of data, including the levels of packet loss within servers over a set period of time. This can help you in an audit to establish whether the performance of a particular server is degrading. If the performance declines, you can compare this data with configuration changes to ensure that your network is using the optimal settings, and resolve the issue without having to go through a more thorough investigation of your network. The data is already collected and ready to be analysed.

Why Configuration & Compliance Management Is Crucial

Why Configuration & Compliance Management Is Crucial

Network security is of paramount concern for all businesses in 2021 and beyond, one facet of network security that should be at the forefront of most organizations is Configuration and Compliance Management.

Creating and enforcing configuration and compliance management ensures that all your network devices are configured to meet your organisation’s standards and requirements. It also encapsulates all connected devices and helps identify potential risks.

The average cost of a cybercrime attack on an Australian business is $276,323. It then takes a company an average of 23 days to recover from an attack, this stresses the importance of having configuration and compliance in place. Simple processes for opConfig involve backing up all configuration data of your network devices, comparing configuration between your devices, and creating events when configuration changes. When it comes to recuperating from an attack or fixing the problem caused by a breach, heavy losses of time and money are a continual variable amongst many businesses, these are reduced by using opConfig if they occur at all.

Unauthorised devices, installing non-compliant software, or user errors are just a few ways of how systems can be compromised. From Open-AudIT to monitor new devices on a network or non-authorised software installation to using opConfig to monitor default passwords enabled, these risks can be reduced.

 

Early warnings are paramount to network security

Early warnings are essential for network security. If you can detect a security or compliance breach early, it’s easier to stop and prevent damage. But most companies don’t have the tools they need to do this effectively. Despite this, Opmantek senior engineer Mark Henry said many IT systems were running with low-scale early warning solutions.

“Generally speaking, a lot of the customers that we talked to, who haven’t adopted NMIS (Network Management Information System) as their network monitoring solution, are sitting down around the level zero or level one area (Gartner’s IT Service Management Maturity Model). That’s also the same for many kinds of low end, off-the-shelf, free or open-source monitoring solutions,” he said.

The truth is that most companies don’t have the time or resources to monitor their networks 24/7. Using NMIS, a reliable and robust monitoring system, means you don’t have to.

 

The benefits of an integrated network management information system

Network Management Information System (NMIS) is an open-source network management system that provides real-time monitoring, configuration, and troubleshooting capabilities. It’s used by many companies worldwide who are looking for ways to manage their networks efficiently, integrating this with other modules that Opmantek offer will help build an efficient and effective strategy to help mitigate network security risk.

Open-AudIT can be installed onto Linux, Windows, or Virtual machines and once installed, needs only credentials and a subnet to discover all the devices attached to that network. Integrating Open-AudIT and NMIS is incredibly easy, Open-AudIT will discover all the devices on your network and with a click of a button, they will all be managed by NMIS, read more here. Integrating opConfig into this is a matter of importing the nodes from NMIS and then creating/applying a credential set for that node, detailed here. From here, we have a system in place that will discover any devices on your network, monitor all software installations, monitor the status/availability of devices, and report on any configuration changes.

4 Best Practices For Automating Your Network Management

4 Best Practices For Automating Your Network Management

This excerpt comes from a blog originally posted on MSP Insights

Murphy’s Law states: “Anything that can go wrong will go wrong.” Equipment always breaks when you’re on vacation, often when the on-call engineer is as far away as possible, and with little useful information from the network management software (NMS).

 

It’s critical for a network to be available 100% of the time and always performing at 100%. Network management is a core component of IT infrastructure that is put in place to minimize disruptions, ensure high performance, and help businesses avoid security issues. Network architectures and networking products handle the brunt of the work, but management tools and technologies are essential for picking up the slack and allowing the shift from reactive to proactive strategies.

 

Network automation can automate repetitive tasks to improve efficiency and ensure consistency in network teams. Ultimately, automation will improve the meantime time to resolve (MTTR) and drive down the total cost of ownership (TCO). Network automation enables staff to gain process and configuration agility while maintaining compliance standards. It will help simplify your network and lower maintenance costs.

 

Save Time And Money With Automation

According to Gartner, “The undisputed number one cause of network outages is human error.” As humans, we all make mistakes, which is why businesses must have comprehensive automation in place. Automation can reduce the likelihood of issues being missed by ensuring consistency and reducing the need for tedious manual configuration. It also can save time, money and improve productivity. The following are four steps organizations can take to build a reliable and agile network through automation.

 

1. Implement Operation Process Automation (OPA)

OPA is about getting the right systems in place to automate repetitive operational tasks to improve efficiency and ensure consistency in operations teams. OPA delivers process automation specifically to IT and network operations teams. As well as emulating actions that network engineers take within a network management system, OPA also can perform advanced maintenance tasks, assist in the interpretation of network data, and communicate effectively with other digital systems to categorize, resolve, and escalate potential network issues. Ultimately, OPA is about improving the MTTR and decreasing the cost of operations.

 

2. Improve Configuration Management

When considering automation solutions to scale your business, a critical variable to consider is time saved through automation compared to the amount of time tasks take if performed manually. A significant amount of administration time is consumed managing configurations and firmware updates, which could be better spent on proactive tasks. Organizations looking to become more efficient should consider an automated network management tool that integrates configuration management to reduce the risk of human errors and enable easier implementation of network-wide changes. This concept is not new, and it is the fundamental basis of making impactful decisions on how your organization can scale.

 

3. Single View Multi-Vendor Support

Most networks are composed of elements from multiple manufacturers. This can create challenges when overseeing the elements of each management system. A better, more efficient approach is to find and deploy management tools that offer true multi-vendor support. This will reduce the number of tools needed for day-to-day tasks and eliminate the need for learning and maintaining multiple management tools, which will improve operational responsiveness and efficiency.

 

4. Policy-Based Management Systems

Many common network administration activities should be handled by the network management system automatically. These systems should not require repeated configuration but be configured through a policy that captures the business rules and ensures that devices are handled consistently. Automated device discovery and classification is another important aspect, automatically determining what the device is, what to monitor, and what type of alerts and events will be generated, all without human intervention.

 

Combining People And Process Automation

According to Forrester, 56% of global infrastructure technology decision-makers have implemented/are implementing or are expanding/upgrading their implementation of automation software. It’s important to note that automation does not mean the replacement of individuals. Instead, it can benefit IT workers, by transferring routine and tedious elements of managing networks to machine learning models that can reduce the noise from the vast number of alerts and notifications. For organizations that are looking to scale, a combination of people and process automation will yield the best results book a demo from our experts to learn more.

How To Leave Work At 5 PM: Visibility, Event Management & Automation

How To Leave Work At 5 PM: Visibility, Event Management & Automation

This excerpt comes from a blog originally posted on Packetpushers.net

As organizations manage increasingly interdependent network infrastructure in an increasingly chaotic world, how can you, as a Network Operations professional, maintain control of your network without losing control of your time?

The answers are: network visibility, flexible event management, and powerful automation. All of this is possible within Opmantek’s network management platform. The software streamlines workflows and lets network engineers and operators accomplish more work with fewer distractions, allowing them to go home on time.

The Importance Of Visibility

We often hear from network engineers that they don’t know what devices are on the network or where they’re located. This lack of visibility introduces security risks and increases Mean Time To Recovery (MTTR). The ability to see as much of the network as possible on a single dashboard allows for fast response times when you and your team need them most.

The robust network visualization tools built into Opmantek’s opCharts and opEvents give you the ability to see a network and react in real-time to precisely what’s happening with confidence. That’s essential for daily operations and in emergencies. For example, did you know that storm-related outages cost the U.S. economy up to $55 billion every year? When a major storm like Hurricane Sandy blasts through your infrastructure overnight, you’ll be able to identify the points of failure and…READ ON.
