Much has been said about protecting the ransomware attacks, from simply keeping your IT assets up to date to architectures zero trust and more elaborate (and expensive) solutions.

Currently, attacks Ransomware they migrated from simple targets (small companies) to large corporations and, consequently, their redemptions went from a few dollars (bitcoins) to millions of dollars, directly impacting the image of companies, as well as direct and indirect losses with post-attack shutdowns.

But how to protect what really matters, your information?

Understand that all "the basics" must have been done: up-to-date IT environment, a good detection and response solution and at least a monitoring of your critical environment through a SOC specialized with report straight to board of the organization to present the operational risk of IT.

But we will not deal with this here in this text. Let's talk about the last resort possible for an organization to continue to exist with its data, as the attack can have a level of sophistication that can circumvent all existing controls. (As happened in some organized attacks with a good cybersecurity weapon – yes a good one) exploit is considered a weapon nowadays)

The last bastion of protection for your data should be to take the vault approach to your data, where you will keep a copy of the data. crown jewels, using the three actions below:

  1. Security by design – the idea is that your data vault does not accept incoming connections and only connects to the assets it will copy the information to, granularly controlling all connections. Every connection from an administrator must occur only through a jumpserverin a very controlled way, monitoring every action of the administrator.
  2. The more temporal data the better – having a good process for copying and storing data is essential, since a backup can also have its integrity compromised, so one should look for a process that saves complete and incremental historical versions. For example, daily copies to your incremental vaults, four completed weeks and twelve monthly copies stored for a long period. This means that you always have at least 7 incremental days, 1 month of full weekly copies and one year of monthly copies, to have a wide range of recovery options within the RTO and RPO required by the business.
  3. Do not use? Disconnect — what's the use of having the safe with you? - the premise that the safe is only connected to the network when backups are performed, so you protect the integrity of the safe when it is not in use, remember it is the bastion of your company's data and must be protected as such. Even many companies take the weekly copies to keep on another site, to protect against other disasters. If the choice of your vault is an IaaS (infrastructure as a service) provider that might be a good candidate, think of different providers and different locations, as the same logic above.

With these three premises for your data vault, for sure, when all else fails, you will have your crown jewels, your data, to continue your business and consequently save millions of dollars against a Ransomware attack or any other catastrophe.
