EDM Dictionaries

In the context of Data Loss Prevention (DLP), Exact Data Match (EDM) refers to a technique used to identify and protect sensitive information by comparing data against a predefined set of values or patterns. Here's how it generally works:

1. Define Sensitive Data: First, organizations create a reference set or "fingerprint" of sensitive data. This could be a list of Social Security numbers, credit card numbers, or other personally identifiable information (PII) that needs protection.

2. Data Scanning: The DLP system scans data across various locations, such as databases, email communications, or file systems, looking for exact matches to the predefined sensitive data.

3. Policy Enforcement: If an exact match is found, the DLP system can trigger actions based on predefined policies. This might include alerting administrators, blocking access, or encrypting the data to prevent unauthorized use.

4. Reporting and Monitoring: The system typically provides reports and logs to help organizations monitor and manage data protection efforts.

EDM in DLP is particularly useful for scenarios where exact matches are necessary to identify specific sensitive data. It offers a high level of accuracy in detecting and preventing the unauthorized disclosure of confidential information.

To create an EDM Navigate to Policies section Select EDM Dictionaries and click On Add New EDM.

Provide the Exact Data Match Name, Description, and upload a sample CSV data file (ensure no real data is used). Click On Next.

Define fields & match conditions tab, by selecting at least one primary and any necessary secondary fields.

Scroll down Click On Create Dictionary.

Download EDM Dictionary tab, copy the Dictionary ID, and download the Data Indexer Tool jar file, Download the EDM Library Zip File(For Windows or Linux) and Extract the zip file.

Click on Next.

In Connect & Configure tab, Proceed to generate a key in Step 2 by Entering the API key name, description, selecting 'EDM Indexer' for key usage, granting read/write permissions, and setting the expiry date to 'Never expires.'

After creating the key, copy the key and secret, and save them in a notepad.

In Step 3, place the CSV, jar files and Extract Zip Files in the same folder.

Open the folder in Command Prompt and ensure that Java is installed on the system.

In Step 4, Run the following command in the Command Prompt to index the data:

Replace the placeholders with the appropriate values.

In Step 5, upload the generated EDM Rulepack to the Swift Platform under 'Upload XML Rulepacks' and finish the process.

Once complete, your EDM dictionary will be created and show as 'Indexed' with a green status.

You can now edit your EDM dictionary as needed by clicking on Indexed.
