Data Backup and Data loss prevention (DLP) ensures that sensitive or vital information is not sent beyond the
business network. The phrase refers to software that allows a network administrator to regulate
the amount of data that users may send. DLP products utilize business rules to categorize and
secure private and vital data, ensuring that unauthorized users do not disclose data
unintentionally or maliciously, putting the company at risk.

For example, an employee would be refused access if he or she attempted to transfer a business email outside

the corporate domain or upload a company file to a consumer cloud storage service like Drop box.
Insider risks and strong data privacy regulations, many of which have stringent data protection or
data access requirements, are driving organizations to implement DLP.


Why is data loss prevention necessary?


A data loss prevention plan is required to protect your data, protect your intellectual property,
and comply with requirements. Your company’s confidential/classified information is protected
by DLP systems from being lost, mishandled, or accessed by unauthorised personnel. According
to a Gartner CISO research, data loss prevention (DLP) is the top priority for CISOs. DLP is
frequently defined as any solution or process that identifies private data, tracks it as it moves
through and out of the organization, and prevents unauthorised data disclosure by setting and
enforcing disclosure policies. Businesses utilize data loss prevention (DLP) because sensitive
data might be held on a variety of computer equipment (physical servers, virtual servers,
databases, file servers, PCs, and so on).


What is the DLP mechanism?


By monitoring, identifying, and blocking sensitive data while it is in use (endpoint activities), in
motion (network traffic), and at rest, DLP software detects and prevents data breaches/data
exfiltration transmissions (data storage).


The cornerstone of DLP software is content inspection, which uses a variety of methods to
discover policy violations. To begin, content inspection is based on rule-based expressions that
are discovered and acted upon by data loss prevention software. Credit card numbers with 16
digits are a nice example of this. If you try to email a credit card number (beginning with a 4, 5,
or 6), especially with the 3-digit security code and expiration date, the DLP software will either
block the email or automate the blocking.


Types of Data loss prevention


Network DLP, endpoint DLP, and Cloud DLP are the three basic forms of data loss prevention
software.

DLP on a network


DLP in the context of network DLP solutions provide you a better understanding of your
company’s network, allowing you to monitor and control information flow through the network,
email, and the internet. DLP software analyses network traffic and creates security policies to
limit the risk of data loss while maintaining regulatory compliance. By implementing security
policies, DLP software can permit, restrict flag, audit, encrypt, or quarantine questionable actions
that infringe your company’s information security standards.


DLP for endpoints


Desktops and laptops are the essential instruments of modern business. According to new study
from vArmour, 76 percent of employees in the United States work from home.


DLP Cloud


As enterprises increasingly shift their corporate data and apps to the cloud, cloud DLP is critical.
It protects business-critical tasks from being disclosed, mishandled, or lost. Cloud DLP solutions
protect your data in the cloud by encrypting sensitive data and ensuring that it is only delivered
to cloud apps that have been authorized by your business. Today’s advanced cloud DLP systems
can recognize, categorizes, eliminate, or change private content before it is transported to a cloud
environment, protecting your data from cyber-attacks, hostile insiders, and unintended
disclosure.


Components of a Data Loss Solution


Secure data in transit network edge equipment can scan traffic for sensitive data sent in a way
that violates security rules.


Endpoint security endpoint-based agents may track and govern data flow between people, groups
of users, and other parties. Some endpoint-based systems can identify and prohibit attempted
communications in real time, as well as provide user feedback. To safeguard data at rest, access
control, encryption, and data retention policies can all be employed. Keeping data safe when in
use certain data loss prevention (DLP) systems can identify and report undesired data
transactions that users may initiate on purpose or by mistake. It is vital to identify data and
determine whether or not it should be protected. Data can be classified as sensitive either
manually or automatically.


Data Loss Prevention (DLP) and File Security Solutions


A DLP approach should include file security solutions like Imperva File Firewall. These
technologies protect data in transit and at rest, as well as identify file-based data breaches.
Imperva File Firewall protects against data breaches by doing the following:

Monitoring and recording granular use data, such as user, department, file accessed, file
type, and operation response time, for all critical files.


File activities that contravene security regulations are detected and blocked automatically.
Using machine learning to detect insider threats by detecting anomalous or suspicious
user activity.


By identifying and preventing common file access patterns, ransom ware assaults can be
mitigated.


For compliance and investigative reasons, auditing and reporting on all file operations.
