An effective Data Loss Prevention (DLP) policy is designed to detect and prevent unauthorized access or transmission of sensitive information outside of the corporate network. The DLP policy controls and sets guidelines for the handling of critical data to safeguard it from loss, misuse, or unauthorized access. In contrast, Password and BYOD policies focus on authentication and the use of personal devices in the network, respectively. Remote access policies set guidelines for accessing the network from external locations, while an onboarding policy outlines the procedures for integrating new employees or users into the network. A security policy is a broader term that includes many sub-policies, but the question pertains specifically to protecting against data losses.
