Data loss prevention (DLP) is a tool that ensures sensitive or critical data is not leaked outside the organization, either accidentally, deliberately or maliciously. DLP software classifies and tracks data to prevent it from leaving the network via unauthorized channels. These solutions detect leakage and exfiltration by monitoring sensitive data while it’s in use, in motion, and at rest.
DLP can therefore be seen as a policy enforcement that utilizes a number of tools to achieve data security within your company. These solutions must work in cooperation with your existing IT infrastructure, your current data usage policies and your business needs. The means by which this data is filtered, encrypted and handled must be done speedily and accurately without affecting business operations negatively.
Confidential data can reside on a variety of computing devices (physical servers, virtual servers, databases, file servers, PCs, flash drives and mobile devices) and move through a variety of network access points (wireline, wireless, VPNs, etc.), there are a variety of solutions that are tackling the problem of data loss, data recovery and data leaks.
Data loss prevention (DLP) is a solution that identifies confidential data, tracks that data as it moves through and out of the enterprise and prevents unauthorized disclosure of data by creating and enforcing disclosure policies.
As the number of internet-connected devices skyrockets into the billions, data loss prevention is an increasingly important part of any organization’s ability to manage and protect critical and confidential information. Examples of critical and confidential data types include:
• Intellectual Property: source code, product design documents, process documentation, internal price lists.
• Corporate Data: Financial documents, strategic planning documents, due diligence research for mergers and acquisitions, employee information.
• Customer Data: Social Security numbers, credit card numbers, medical records, financial statements.
First of all, you will need to create a data classification policy; i.e, establish what data is sensitive, what data is classified and what data is safe for public consumption. You will also need to know what acceptable use of that information is, and what constitutes a breach of the policy. Based on these policies, users will find that when sending emails, copying data or transmitting information, they will be blocked or made to justify their actions; otherwise, that data will be encrypted and rendered unreadable by the recipient.
An example of this policy when applied to email is as follows: the DLP scans emails, looking for specific fingerprints to run against the stored triggers that are set out in the policy. This allows remediative action to take place once a DLP event has been detected. Examples of these actions are:
In cases where certain employees are allowed to send out confidential information, auditing tools must be in place to check what has been sent for specific periods of time so that data security is managed and reviewed.
Data loss prevention is a billion dollar industry, primarily due to the growing risk of data loss at the hand of company insiders. The core benefits of DLP solutions are typically to adhere to Regulatory Compliance, to Monitor Sensitive Data Movement, and to prevent critical files from leaving via specific egress points.
