Data Loss Prevention Policy

Sample Templates, PDF Resources, and Best Practice Tips

TL;DR

TL;DR: 

  • A robust data loss prevention (DLP) policy is essential for protecting sensitive data from unauthorized access and ensuring regulatory compliance. 
  • This guide outlines key elements of an effective DLP policy, including data identification and classification, access policies, secure data handling procedures, technical controls, and breach response plans.


Data is one of the most valuable assets for any organization today. However, with data spread across complex IT ecosystems and accessed by employees, contractors and third parties, the risk of data loss through accidental exposure or malicious exfiltration is higher than ever. A robust data loss prevention (DLP) policy is essential to govern data access, prevent breaches and ensure regulatory compliance.

What is a Data Loss Prevention Policy and Why is it Important?

A data loss prevention policy provides guidelines for protecting sensitive or confidential data from unauthorized access, exposure or exfiltration. It classifies data types, defines appropriate access levels and permissions, specifies technical controls and security measures, and outlines protocols for responding to policy violations.

The key objectives of a DLP policy are:

  • Identify and classify sensitive data repositories
  • Limit data access to authorized users
  • Prevent unauthorized data sharing or transmission
  • Detect potential data leakage
  • Define incident response procedures

Key Elements of an Effective Data Loss Prevention Policy with Sample

Crafting a comprehensive DLP policy involves bringing together inputs from key stakeholders across the organization. Here are some best practices to build a robust policy:

Identifying Sensitive Data in Your Organization

The first step is to identify and classify sensitive data. This can include:

  • Personally identifiable information (PII) like social security numbers, financial information and healthcare records
  • Intellectual property such as proprietary source code, trade secrets, and confidential business plans
  • Payment card data and credentials like credit card numbers and login passwords
  • Data subject to regulatory compliance such as HIPAA, GDPR, CCPA etc.

Perform Data Discovery and Classification

Once sensitive data is identified, comprehensive data discovery using scanning tools will locate where this data resides - on premises systems, cloud platforms, databases, files shares etc. Automated data classification tools powered by machine learning can classify data and content as sensitive or non-sensitive across disparate systems.

Defining Access Policies and Permissions for Data Protection

The DLP policy should clearly define data access policies based on user roles. For example, PII data may only be accessible to HR staff, while source code should only be accessed by engineering teams. The principle of least-privilege should be followed to restrict access.

Specifying Secure Data Handling Procedures to Prevent Loss

Procedures for secure data handling by authorized users should be established, such as:

  • Mandatory access controls for copying, downloading or printing data
  • Encryption requirements for data in transit and at rest
  • Secure channels approved for data sharing like encrypted email
  • Protocols for transmitting data to external parties

Selecting Data Security Controls for Enhanced Protection

Technical controls are the teeth of a DLP policy. Controls like the following should be implemented:

  • Next-gen firewalls, web gateways and antivirus to prevent malware-based data theft
  • Data loss prevention tools using deep content inspection to detect unauthorized data usage
  • Access management tools like multi-factor authentication and single sign-on
  • Email and web content filtering to prevent data leakage via the internet
  • Blocking access to insecure cloud apps not approved by IT
  • Endpoint protection including disabling external media and controlling USB devices

Defining a Breach Response Plan for Data Loss Incidents

The DLP policy should define a response plan in case of a data breach incident such as:

  • Escalation procedures and stakeholders to be notified
  • Investigation protocols to determine root cause and extent of breach
  • Communications plan for informing customers if PII is compromised
  • Provisions for regulatory and legal compliance if needed
  • Plans for recovering compromised data from backups
  • Post-breach analysis to improve data security controls

Data Loss Prevention Policy Tips for Successful Implementation

Organizations often find it useful to start with a pre-defined data loss prevention policy template and customize it to suit their specific requirements. Several sample DLP policy templates are available, such as the data loss prevention policy sample template provided by the SANS Institute. 

This contains sections for specifying sensitive data types, handling procedures, technical controls, and incident response. Companies can also refer to the data loss prevention policy template PDF published by the National Institute of Standards and Technology (NIST), which provides a framework aligned with ISO 27001 standards. 

When using pre-built templates, be sure to validate that all regulatory and compliance obligations are met. Useful data loss prevention policy tips are also available from industry experts to guide policy drafting and implementation.

When developing a data loss prevention policy, it's important to consider modern DLP solutions that can enforce your policy across various platforms. Strac's comprehensive DLP approach offers insights into implementing effective policies that cover both cloud and on-premise environments.


Best Practices for Implementing a Data Loss Prevention Policy Successfully

To ensure a DLP policy translates effectively into practice, organizations should focus on the following:

Securing Executive Buy-In for Data Protection Initiatives

Get buy-in from senior leadership on the importance of data security and the need for enforcing DLP controls. Conduct awareness training on potential data breach impacts.

Phasing in DLP Controls for Gradual Implementation

Start with non-intrusive monitoring controls and gradually phase in restrictive policies. Quickly blocking user activities can disrupt operations.

Developing User Awareness for Data Loss Prevention

Conduct training to develop employee awareness on data security risks, compliance needs and relevant policies. Highlight consequences for negligence.

Testing Policy Effectiveness to Ensure Data Protection

Test DLP policy effectiveness through controlled simulations. For example, send fake credit card data via email to see if controls block transmission.

Monitoring Alerts and Incidents for Timely Response

Tools like SIEM solutions should collect DLP alerts and incidents so that policy violations can be investigated and addressed.

Tuning Policies Based on Insights for Enhanced Protection

Analyze information from DLP monitoring tools to identify gaps and policy tuning needs. For instance, increase detection sensitivity for PII data.

Reviewing Periodically for Updates to Data Loss Prevention Policy

Update the DLP policy regularly based on changes to the threat landscape, business needs, and regulatory obligations.
