4 Reasons Your Organization Needs a Data Loss Prevention Strategy

When deciding how to go about protecting your company’s sensitive data, there are plenty of different solutions to choose from, such as endpoint controls, file system controls, or even network traffic inspection. However, the technology is only as effective as the people and processes in charge of configuring, managing, and monitoring it.  That’s why it’s important that technology is not your only method of protecting your data, but instead a way to complement a strategy consisting of internal policies, procedures, and operations. This approach is called Data Loss Prevention (DLP), and should be implemented by every organization, regardless of size.

Why exactly should you consider a DLP strategy?  Here’s four of the main reasons:

1. You have sensitive information.

You have data; every company does. That data is important to your business, your customers, and you. We frequently hear about companies experiencing a data breach and only finding out months, or even years later, that there was a breach.  Take Marriott International, for example.  Marriott acquired a hotel chain called Starwood in 2016. What Starwood and Marriott didn’t know at the time was that Starwood had been breached in 2014. The attacker remained in the system after Marriott and Starwood merged their systems.

It wasn’t until 2018, four years later, that the breach was discovered. If Marriott had implemented an effective DLP strategy, they could have detected and purged the breach sooner through a number of different preventive or investigative procedures.

Your data is sensitive to your business’ success and should only be handled by people that you trust: you and your employees (on a least-privilege basis).

2.  Human error.

Employees can unintentionally leave sensitive data vulnerable. Whether that means they leave file systems vulnerable to unauthorized access, forget to flag an email as sensitive that contains Personally Identifiable Information (PII), or hand their coworker removable media with a list full of Social Security Numbers used for background checks, it should go without saying that humans can make mistakes.

That’s where a thorough DLP strategy can help; if a DLP solution is configured and monitoring your environment according to your policies, you can set enforced rules that prevent these mistakes and generate accurate reports and alerts.  Combine this with employee security training, and you have a chance to fix the potential damage to your business before it happens.

If you lack the resources to set up those configurations, reports, and alerts, you can hire a Managed Security Service Provider (MSSP) to take care of those for you.

3. Malicious Insider threats.

Consider the following scenario:

You hire an individual and they have been performing expertly. They seem to enjoy the job and they haven’t requested a raise in years. Little did you know that when you hired them, they immediately started stealing and selling your data to the highest bidder. This is an extreme scenario, but it does happen. There are organizations and nation-states that will pay top dollar for your sensitive data, and they will gladly target your employees to do it.

Implementing a DLP strategy that includes thorough scenario training can discourage your employees from being persuaded into selling your data, as well as help catch those who do it. With properly trained employees and an effective chain of command, insiders can be reported by their peers at every possible point and be stopped before serious damage is done to your business’ reputation and resulting profits.

4. This is the 21st century of interconnectivity.

We’re connected to everything these days; it’s human nature to crave popularity, which has caused an obsession over online presence that doesn’t always take into account protecting sensitive data. When there’s so many easy ways to send, receive, and view different types of communications from so many devices, it’s easy to blur the line of what belongs on which devices.

We’ve already pointed out that humans make mistakes; why not use a well thought-out DLP strategy and implemented technology to keep an eye on your critical data and tell you when your employees do make those mistakes?  Whether you implement your own monitoring team or contract with an MSSP, a DLP solution will solidify those previously blurred lines of where that data does and doesn’t belong.

In summary, you need a DLP strategy because you have sensitive data, you employ humans who can or might want to sell your data, and even the best policies and procedures can’t stop someone from unknowingly exposing your company’s data. A Data Loss Prevention Strategy written with supporting technologies in mind can mitigate those risks.
