# Data Loss Protection

All component configurations are classified broadly into 3 section

* ​[​Basic Information​](/data-pipeline/components/component-base-configuration.md)​
* Meta Information
* [Resource Configuration​](/data-pipeline/components/resource-configuration.md)

**Data Loss Protection component in pipeline used to protect or mask the incoming data by using the several techniques so that the loss of important data can be ignored.**

## **Configuring Meta Information of Data Loss Protection**

* **Column name:** Enter the column name whose data has to be protected.
* **Rule type:** Select the rule type to hide the data. There are four types of rules available by which the data can be protected.
  1. **Redaction:** Redaction is a data masking technique that enables you to mask data by removing or substituting all or part of the field value.
  2. **Masking:** By selecting this method, the data can be masked by the given character. Once this option is selected, the following value needs to be given:
     * **Masking character:** Enter the character by which the data will be masked.
     * **Characters to ignore:** Enter the character which should be ignored while  masking the data.
     * **Type:** Select either **Full** or **Partial** for masking the data.
  3. **Hashing:**  Hashing is using a special cryptographic function to transform one set of data into another of fixed length by using a mathematical process. Once this option is selected, then select the Hash type from the drop down to protect the data. There are 3 options available under the Hash type:
     * **sha 256**
     * **sha 384**
     * **sha 512**
  4. **Date generalization:** For this rule, select a column which is having only date values. There are four(4) options under this rule:
     * **Year**
     * **Month**
     * **Quarter**
     * **Week**
