About Data Loss Prevention

With the prevalence and damaging effects of data breaches, organizations now see digital asset protection as a critical component of their security infrastructure. Data Loss Prevention safeguards an organization's sensitive data against accidental or deliberate leakage.

Data Loss Prevention allows you to:

  • Identify the sensitive information that requires protection using data identifiers

  • Create policies that limit or prevent the transmission of digital assets through common transmission channels, such asĀ email messages and uploaded files

  • Enforce compliance to established privacy standards

Before you can monitor sensitive information for potential loss, you must be able to answer the following questions:

  • What data needs protection from unauthorized users?

  • Where does the sensitive data reside?

  • How is the sensitive data transmitted?

  • What users are authorized to access or transmit the sensitive data?

  • What action should be taken if a security violation occurs?

This important audit typically involves multiple departments and personnel familiar with the sensitive information in your organization.

Trend Micro uses Data Loss Prevention templates to tag and detect sensitive content by a set combination of data identifiers. A template combines data identifiers and operators (And, Or) in condition statements. When a set of data matches the criteria of a condition, Data Loss Prevention triggers a policy action. For example, a file containing data matching the All: Names from US Census Bureau AND US: HICN (Health Insurance Claim Number) templates, triggers the HIPAA policy.

TMWS provides some Data Loss Prevention out-of-the-box templates for regulatory compliance initiatives, such as GLBA, PCI-DSS, SB-1386, US PII, and HIPAA, and integrates them into Data Loss Prevention profiles to help manage the distribution of sensitive data across the network. Administrators can scale profiles to apply to the entire company, groups, or specific endpoints.
