We hear a lot about the need to back important business data & applications. However, backing up your network configuration information is equally important.
The latest update to the UK Government’s Cyber Essentials scheme has changed its guidance around backups to reflect the growing threat from ransomware. It stresses the importance of making regular backups in order to mitigate the threat (by ensuring you can restore systems should the need arise).
Importantly, it isn’t only your data and applications for which you should be making regular backups. It’s also important to be making regular backups of your networking configuration and operational data.
It can be easy to overlook the necessity to backup your network configuration data. However, it is just as important to take regular backups of this information as it is the rest of your organisational data and applications.
Imagine the scenario. A cyber-attack has brought down your systems. Your IT department is working urgently to restore your applications as quickly as possible, so you can get your users and your business back online.
Yet no one can access any of the restored data because your network is still down! You need to restore all your network devices before users can access vital data and applications. It can be difficult and time-consuming to do this without good network configuration backups if you don’t have the right expertise or up-to-date documentation.
There are a variety of tools that enable you to make immutable backups of your network devices, cloud networking configuration and other operational data. Usually, they will be proprietary solutions – depending on the network tools you use. Your IT partner will be able to recommend a suitable solution.
The key is to ensure that your backups are made regularly and that they reside on a different platform to the rest of your operational data. This way, they can be accessed easily in the event of a recovery situation.
You’ll also need to ensure that your backup stores your most recent correctly working configuration. For complex environments, manual backups are unlikely to suffice. An automated solution makes it more likely that your most recent correctly working configuration will be captured.
From this, you can then restore your network and give users the access they need while keeping restoration downtime to a minimum.
