Data Loss Prevention & DLP Security


Have you ever discovered that a colleague was accidentally sharing private client data in a presentation, such as a telephone, or credit card number? Even worse, have you ever discovered that someone was maliciously sharing sensitive data to a competitor or company outsider? These scenarios can be discouraged and even entirely avoided with a data loss prevention strategy in place.   

What is data loss prevention?

Data loss prevention, or DLP for short, is a strategy that aims to protect sensitive or critical business data from leaving the organization’s environment, either accidentally or maliciously. DLP has two major components that go hand-in-hand to ensure security of an organization’s data.

  1. DLP Solutions and Policies
  2. Internal Training

Data loss prevention solutions scan data for patterns that identify sensitive or personally identifiable information (PII) such as phone numbers, social security numbers, and credit card numbers. It is important to identify where confidential data is stored, who’s accessing it and actions taken against it. DLP tools scan and process content in real-time preventing distribution of sensitive information further solidifying your security and privacy position.

A Data Loss Prevention solution may also be an important part of your security and compliance program if your organization accepts or processes payment cards. The PCI Security Standards Council has created PCI Security Standards to protect clients’ payment information. The goals of the PCI Security Standards are to:

  • Build and Maintain a Secure Network
  • Protect Cardholder Data
  • Maintain a Vulnerability Management Program
  • Implement Strong Access Control Measures
  • Regularly Monitor and Test Networks
  • Maintain an Information Security Policy

Via PCI Security Standards Council.

Internal training on your company’s Data Loss Prevention strategy is important so everyone within the organization understands why they’re unable to send certain documents outside of the organization, or why they’re unable to print or save a certain file to Dropbox for example. 

Why do businesses need data leak prevention?

It is crucial that organizations have a DLP plan to protect critical data. If an organization fails to protect their own and client data, they risk data breaches by hackers, thieves, or employees, which can result in:

  • Steep fines
  • Legal risk and liability
  • Negative PR
  • Lost revenue due to poor reputation
  • Decreased competitive advantages due to leaked IP or proprietary information

A data loss prevention plan will help your organization gain and keep control of information to help ensure that the above does not happen. Bishop can help you build a DLP strategy and identify which policies are needed to protect your organization’s data. The first step is identifying what data you have in your environment with a file system audit.


DLP in Office 365

The Office 365 Security and Compliance Center allows you to create DLP policies and rules to automatically protect data across Office 365, including SharePoint online and OneDrive for Business. These automatic policies can help your organization meet compliance and regulatory requirements, like HIPAA and PCI, and can be set up in an easy-to-manage central location. The Office 365 Compliance Center enables you to specify where, when, and how you’d like to protect your data, what conditions must be met, and what actions should be taken against this data in an effort to protect it.
