How Does a DLP Solution Work?

Data Loss Prevention (DLP) programming shields information from data loss or theft that could affect your organization majorly. DLP solutions cover various strategies to secure information – like encryption, classification, monitoring, and policy enforcement. You can utilize DLP solutions to classify and focus on information security. You can likewise use these solutions to guarantee access policies meet regulatory compliance. DLP solutions can go beyond simple identification, giving alerts, encryption, and isolating information. The other standard features of DLP solutions are Monitoring, Filtering, Reporting, and Auditing of the data concerned.

Knowing how a DLP solution works can be reduced to a straightforward pair of directions: distinguishing sensitive information that needs to be secured and preventing losing the data afterward.

DLP solutions are comprehensively grouped into two classifications: Enterprise DLP and Integrated DLP. 

  • Enterprise solutions are comprehensive devices meant to protect the information in all states, i.e., in motion, in use, and at rest. These solutions are extensive and packaged in agent software for workers and work areas, virtual and physical devices for observing networks and e-mail traffic, or soft devices for information recovery.
  • Integrated solutions may focus only on one state or could be coordinated into a different single-purpose tool. These arrangements are restricted to SEGs, SWGs, ECM platforms, information classification devices, e-mail encryption items, and CASBs.

DLP solution providers utilize various DLP strategies to track down sensitive information or needs protection. At times this includes searching for duplicates of records or information you’ve provided. It includes searching through your data stack on different occasions, looking for fine details of the sensitive data. A DLP solution relies upon various key innovations that empower its system to effectively distinguish the sensitive information that organizations need to secure and take remediation action to prevent such occurrences.

There are two principle technical ways to deal with DLP:

  • Context analysis looks at metadata or different report properties, like header, size, and format.
  • Content awareness includes taking a report, understanding it, and breaking down its contents to analyze whether it incorporates sensitive data.

Nowadays, DLP solutions consolidate both of these arrangements. At the initial stage, DLP looks at the contexts of a record to check whether it can be arranged. In case the context is lacking, it will look inside the report utilizing content awareness.

There are a few methods usually utilized for content awareness:

  • Rule-based matching or regular expressions is used to analyze the substance of a report utilizing specific guidelines or standard terms, for instance, searching for 16-digit master card numbers. It is powerful as a first filter since it is not difficult to design and process; however, it is generally joined with extra techniques.
  • Conceptual/Lexicon is used by consolidating the utilization of dictionaries, taxonomies, and lexical guidelines, the DLP solution providers, can distinguish concepts that demonstrate sensitive data in unstructured information. It requires cautious customization of every association’s report.
  • Database fingerprinting or exact data matching makes a “unique mark” of the information and looks for definite matches in a data set dump or currently running data set. The drawback of this technique is that it requires making an information dump or using live databases, which can influence performance.
  • Exact file matching makes a hash of the whole document and searches for records that match this hash. This strategy is precise yet can’t be utilized for documents with various versions.
  • Partial document matching can recognize documents where a portion of the content matches, for instance, a similar form that various clients fill up.
  • Statistical analysis can utilize AI calculations for Bayesian analysis to distinguish content that violates a policy or contains sensitive information. These procedures become more effective when more labeled information is input into the algorithm for training.
