Remote Work Data Security Challenges and Cloud-First DLP Strategies

Your workforce is toiling from coffee shops, home offices, and co-working spaces. And now your data, too, is following them everywhere? That is the truth we are dealing with at the present moment. If you’d have told me back in the early 2000s when I was up to my eyeballs in Cisco routers and the sorting out the PSTN’s voice and data mux that one day in the not too distant future we would be securing data that exists all over the world and not just behind a corporate firewall, it would have seemed like a joke. But here we are.

Remote Work Data Risks

The post-COVID world redefined work. The office is no longer a place; it’s a state of mind. And with that change, the headaches for IT and security folks, particularly around Data Loss Prevention (DLP), have grown by orders of magnitude.

Here’s a useful stat to kick things off: 47% of data breaches in 2023 occurred in systems or information that was outside the traditional security perimeter, according to recent research. That’s nearly half! And it’s not hard to see why — the walled gardens of office networks were replaced by coffee shop Wi-Fi, unchecked personal devices and, by definition, a larger attack surface.

But here’s the catch: It’s not only hackers who are doing the hacking. Occasionally, there are leaks from the inside. Workers who are lured away by their kitchen melee, or clicking through personal email on their work computer — accidental exposure is a true concern.

Just a few months ago I worked with a mid-sized financial firm where an employee had uploaded a client spreadsheet to a personal cloud drive, reasoning, “This will be easier to work from home with.” Big oops. It took weeks to catch, and the fallout — possible regulatory fines, loss of trust — had me longing for the good old days when a USB stick was the worst of it.

Cloud-First DLP Approaches

The problem isn’t the cloud, it’s the new battlefield. Migrating applications and data to cloud platforms has been a saving grace during remote work — securing it? That’s a whole different animal.

DLP has evolved. It’s not just about monitoring email or USB ports (remember those days?) anymore. It’s about the discovery of data, the monitoring of data in real time, and the enforcement of policy, regardless of where it lives or moves.

Here is what I would suggest in a strong cloud-first DLP strategy:

• Visibility is king: Purchase tools that can monitor data usage across SaaS apps, cloud storage and endpoints.
• Granular policy controls: Define policies all the way to user roles, data types and the like.
• Work with Zero Trust – yes, I just helped three banks rollout this and believe me on this – integrating DLP into Zero Trust isn’t a choice now.
• Encryption, always: Whether at-rest, in-transit, and ideally in-use.
• Automation of incident response: Time is money. The sooner you find out about it, the better.

Employee Behavior Patterns

This is the tricky part. Employees are human. They are dealing with work-life boundaries as never before. And security fatigue? Real.

Here’s the catch: You can’t simply apply a DLP solution and hope it works without dealing with behavior.

From my desk (fueled by a third cup of coffee) I’ve witnessed how employees — particularly those new to remote work — will go around security if they feel that security impedes their work. Password policies? Oh boy, don’t get me started. I still run into teams who seem to be fighting battles with “password complexity rules” that serve no purpose but making users scribble them on sticky notes.

Better to train, incentivize and communicate. The ‘why’ — your first line of defense in DLP It’s your first line of defense against DLP.

Best Practices for Distributed Teams

Okay, let’s get practical. Here are five must-do tips I always pass on to IT managers and security pros wrestling with DLP in a remote work scenario:

1. Make sure you have a clear remote work data policy, not just a line in the employee’s handbook. That means clear rules about how data is used, stored and shared.
2. Deploy endpoint DLP agents — these afford you granular controls and real-time alerts on laptops, mobiles and tablets.
3. Train incessantly: Phishing and stupidity remain the largest sources of data loss.
4. Leverage unmanaged device policies — ensure personal devices trying to access company data comply with security hygiene.
5. Perform routine checks on your DLP policies and incidents. What worked last quarter? What didn’t? Adapt.

Quick Take

• Traditional DLP has been upended with remote work.
• Cloud requires integrated DLP, with cloud first mentality.
• Your wildcard is your employees’ behavior — train and empower your teams.
• Zero Trust thinking with DLP enforcement is essential.
• Policies should be organic documents, updated periodically.

Poll Question: What is your current position on remote work data security policies?

• We are strong on DLP, especially for remote work
• Traditional Office based DLP Policies only
• Planning to renovate, but have not ordered anything yet
• No official remote work data policies yet

And speaking of leaks — here’s an infographic I slapped together real quick about the most frequent sources in today’s remote world:

To sum all this up — remote work is happening, and if your data security isn’t up to it, you are leaving the door wide open. And I’ll tell you this as someone who lived through Slammer worm madness and is still buzzing from the latest hardware hacking village at DefCon: You don’t get a choice in adapting.

And if you’re cynical about ‘AI-powered’ products that promise magic outcomes — I hear you. That’s hype. Concentrate on what’s real instead: fundamentals and architectural soundness.

Just because the office is empty doesn’t mean your data is safe. It’s tracking your people — across devices, on the web, in phone apps.

So, secure it accordingly. Or risk it all.
