A Look at Data Retention and Deletion Policies and Compliance | Bricktowntom's Market Place Sharing Industry News And Resources To Help You Succeed Online.

There’s an aspect of the compliance conversation too many organizations overlook, and it’s nearly as important as how data gets used: data retention and deletion policies.

Recently, a €14.5 million GDPR fine was issued for a non-compliant data retention schedule. And a new report from 451 Research reveals that 31% of respondents aren’t always following their data deletion and retention policies—or haven’t implemented retention policies at all.¹

It’s a slight improvement over last year’s study but still a clear sign that too many organizations need to tighten up their data management policies and procedures. If you have a data retention and deletion schedule, it’s critical that you’re following it. If you don’t, here’s what you need to know—but note, this isn’t legal advice and you should consult with your organization’s lawyer or legal team.

What Is a Data Retention Schedule?

Data retention and deletion schedules address what happens to data after it’s been used, dictating how long data can be stored and how it’s disposed of. Even if you’re not misusing the data and it’s properly secured, retaining it beyond the cut-off date counts as an infraction .

A data retention schedule can be absolutely critical to this aspect of compliance. A retention and deletion policy will cover:

What types of data are being stored and where—so it can be easily located when it’s time to delete. This includes all traces, such as in backups or file servers.
A permission-based framework for all retained data
Anonymization and encryption policies that will be used
How it’s being processed and why
Why it’s being stored—including if there are legal or regulatory reasons for doing so, such as audits or tax reasons, historic or research purposes, etc.
When it’s being deleted (or moved) and protocols for deletion or sanitization
How you’ll document deletion or anonymization
Roles and responsibilities of individuals monitoring compliance and retention

In storing different data sets, I find one of the most helpful approaches is a tiered backup architecture. It allows you to separate data snapshots that are hot, warm, or cold. A data-only bunker can safely store large amounts of data that aren’t needed for immediate use. Check out this post for an example of a tiered bunker architecture you can create with Pure.

Note: You can set the schedules for data retention and deletion, but they must be justified. You must provide adequate reasoning for the schedule and proof you’re following it.

Why Have a Data Retention Policy?

One of the biggest compliance missteps I’ve seen companies make is keeping too much data for too long. In many cases, keeping too much data for too long can expose an organization to unnecessary risk. It’s a bright, flashing target for bad actors and compliance officers alike. Not to mention, it can open your organization up to tremendous legal exposure.

General Data Protection Regulation (GDPR) calls this an individual’s “right to be forgotten,” and it essentially means a company can’t hang on to their data when it’s no longer needed for processing.² But other regulations, like HIPAA and ISO, can contribute to what should be in your policy, so don’t just stop at GDPR and consult your privacy expert.

The reason for this is that data sitting in archives or graveyards presents more risk for security breaches. If it’s not needed and can be removed, your risk can be substantially lessened.

How to Create (or Improve) a Retention Schedule

First, know that your retention policy should be an integral part of your overall data security strategy. The two are inextricably linked. Start with a security review so that you can align the two. Then, create a data flow map for your organization. Your retention strategy should address data along the flow map, documenting exactly:

What types of data are being stored and where—so it can be easily located when it’s time to delete. This includes all traces, such as in backups or file servers.
A permission-based framework for all retained data
Anonymization and encryption policies that will be used
How it’s being processed and why
Why it’s being stored—including if there are legal or regulatory reasons for doing so, such as audits or tax reasons, historic or research purposes, etc.
When it’s being deleted (or moved) and protocols for deletion or sanitization
How you’ll document deletion or anonymization
Roles and responsibilities of individuals monitoring compliance and retention

Note: Sensitive personal information can be anonymized, which may preclude your need for retention or deletion of that particular data set. However, if this data paired with another data set can make it identifiable, it will still need to be deleted.

How Pure Storage Can Help Support Retention Strategies

Coupled with comprehensive organizational security measures, Pure Storage® can help you meet GDPR and other security requirements and data compliance regulations around the world, without adding more complexity.

The creation of tiered retained data with secure, data-only bunkers: Given that communication is established into, but not out of, the bunker, it’s considered a highly secure location.
Cloud-ready, seamless data mobility: Seamlessly move workloads to support changing business needs, including data sets that no longer have value for processing.
Data and backups safe from encryption or deletion. SafeMode snapshots protect your data, especially critical backups, from accidental deletion, compromised credentials, or encryption during an attack.
Modern data protection: We deliver the most modern data protection solutions, with security and rapid recovery against ransomware threats.
A single control pane for visibility: It’s important to have a clear handle on where your most important data lives at any given time. Pure’s simple setup, effortless operations, and unified control pane make it easy to see what workloads are where, so you can move data sets for deletion.

Your first step is to meet with your compliance officer and include your CISO to make sure everyone’s on the same page.
