Data vaulting is a form of data isolation that creates a copy of data that is
disconnected from the production and core backup environments. Simply put, it is
the creation of a backup copy that is inaccessible from what has historically
been the core attack surface of enterprise IT environments. In a time when
ransomware attacks continue to grow more sophisticated, data vaulting is
essential.



For many customers, data vaulting is necessary to adhere to the 3-2-1 backup
rule. A loose definition of this rule states that, to protect data,
organizations must have multiple copies of backups stored in multiple places.

There are multiple approaches to data vaulting, and implementation will look
different for every organization. Regardless of how an organization incorporates
data vaulting, it is a key component to protecting backups today.


DATA VAULTING METHODS

From a technical standpoint, there are two core approaches that customers can
take to create a data vault. The first is to create an air-gapped copy that has
network isolation from the production and the core backup environments. This
should mitigate -- and, ideally, eliminate -- external connections and
management interfaces that could be compromised by outside attackers.

The 3-2-1 backup rule is a helpful template for a multidimensional backup
strategy.


Air gaps may be physical, where the data copy is located on a physically
disconnected storage system that exists within the customer's data center or is
hosted off-site or by a third party. Air gaps also may be logical, with the
air-gapped data copy located on public cloud storage that is managed either by
the customer via data protection software or by a service provider.

The second main approach is to create an active archive that stores data in a
read-only format and enables controlled access by applications and users.

An active archive is one method to implement data vaulting.


According to IT analyst firm Evaluator Group, there are a few table-stakes
capabilities that organizations must include in data vault implementation. These
include the ability to apply immutability and write once, read many designations
alongside automated control over data copy and movement procedures.

To avoid malicious penetration of the environment, the data vault should have
access control capabilities, including security credentialing, such as
multifactor authentication. Monitoring and reporting are critical to ensure the
health and availability of backups, as well as uncovering potential breaches.
Organizations may use machine learning and analytics to detect signs of
penetration or corruption and conduct security checks to validate data
integrity. Automated recovery from the vault helps to securely restore
operations as quickly as possible.


WHY DATA VAULTING?

These days, the major draw to implement a data vault is for resiliency against
ransomware. Increasingly often, ransomware attackers are targeting primary
backup environments. They understand that the customer is more likely to pay the
ransom if it does not have backups to recover from. Often these attacks are
sleepers, designed to lay dormant for a period of time to avoid detection and
exceed the ability to restore data to a near-term recovery point.

Another challenge is that attackers are going a step further with data
extortion, threatening to expose and sell data if the ransom is not paid. For
these reasons, it is critical to take all measures possible to inhibit attackers
from accessing backup copies in the first place. A data vault becomes an
important safeguard from this standpoint because, unlike the primary backup
environment, it is not inherently designed for accessibility in order to
facilitate recovery.

What is data vaulting and how does it shape modern backups?

Data vaulting methods, such as air gapping and active archives, help isolate and
protect data backups from malicious deletion or accidental data loss.

Air gap backups provide another layer of protection

Air gap backups can provide extra protection from data deletion or intruders,
but admins should exercise caution to ensure the data is encrypted and the
network is secure.

How to use air gaps for ransomware defense

Air gaps can be a valuable last line of defense against ransomware. However,
both logical and physical air gaps have vulnerabilities that can be exploited by
bad actors.

Immutable backups for ransomware defense may not be enough

Immutable backups ensure data cannot be overwritten or changed, making them a
great way to protect against ransomware, but they're not a perfect option.
Here's why.

Use immutable backups to prevent data loss, boost compliance

Immutable backups have gained traction with the rise in ransomware attacks.
However, there are different approaches to immutability and external factors
that come in to play.
