Understanding Cloud Data Loss Prevention: A Beginner’s Guide

Table of Contents

75% of organizations have migrated some or all of their data to the cloud.

As the world is moving to digital infrastructure, businesses have been opting for cloud technology to become more flexible. However, organizations’ wide cloud adaptation has increased the risk of data breaches and thus urgently necessitates robust security measures. Security is a key issue for enterprises because data stored in the cloud faces numerous threats, such as access by unauthorized users and accidental exposure or deletion of sensitive information. 

That is where Data Loss Prevention (DLP) solutions step in. 

DLP is a security strategy for making sure that end users do not send sensitive or critical information outside the corporate network. Organizations are continuing to store and process massive amounts of data in the cloud, making protecting that information crucial. A solid data loss prevention solution reduces the risks of sensitive data from being exposed, ensures compliance with regulations and legislation related to information security and significantly improves the overall protection level for companies working in cloud environments.

Understanding Cloud Security Challenges

Cloud Security Challenges Infographic

When businesses transition their data and operations to the cloud, they face many security challenges. Some of those challenges are:

1. Data Privacy and Compliance

Challenge: Cloud environments often save personal and financial sensitive data, which attracts more stringent compliance regulations such as GDPR, HIPAA or CCPA. 

Why it matters: Violations of sensitive information can result in hefty legal penalties, loss of business, and reputational damage. 

Solution: Set up restrictive data governance and implement security controls (DLP) to abide these regulations. 

2. Data Breaches and Unauthorized Access

Challenge: As Cloud platforms are shared and distributed in nature; hackers have an easy way to intrude your private data. 

Why it matters: Data breaches can cost you millions of dollars or even cost you your business with intellectual property theft and business disruption.  

Solution: Use multi-factor authentication (MFA), encryption, and DLP to detect and prevent unauthorized access attempts.

3. Insider Threats

Challenge: Not just external attackers pose a threat but employees with sensitive data might cause data breach inadvertently or because of malice. 

Why it matters: Insider threats are more difficult to identify than outside hacks, but the consequences can be equally damaging. 

Solution: Enforce robust controls on access and use cloud data loss prevention solutions to monitor and detect malicious activity from within the company.

4. Data Visibility and Control

Challenge: When data is moved to the cloud, it can be more challenging track — where and how the data is stored and who has access to that information.  

Why it matters: A lack of visibility increases the risk of breach and makes it more difficult to detect potential threat. 

Solution: Cloud data loss prevention solutions offer centralized visibility and control over sensitive data to administer protection over all the cloud storage. 

What is a DLP Solution?

Data loss prevention is a collection of different tools and platforms that ensures that sensitive data is not accessed and misused by anyone. DLP solutions play a very important role in protecting data at multiple levels, including when it is being transmitted from one location to another (data-in-transit), stored on a storage device (data-at-rest) and when the data are active or processed by an application, user, etc.

How DLP Solutions Work

Data loss prevention solutions focus on protecting data in three key states:

  • Data in Motion

    This refers to data transmitted over network, such as emails, file transfers or cloud sharing. DLP solutions monitor this traffic to stop data being transferred or leaking when in motion.

  • Data at Rest

    It refers to the data that resides in servers, databases or on cloud. Stored data is scanned by data loss prevention to check and protect it, making sure that sensitive material is encrypted correctly and safeguard from unauthorized access.

  • Data in Use

    This is data used by the users. DLP oversees when files are copied, printed or moved to ensure there is no intentional or accidental mishandling and exposure of the sensitive information.

Role of DLP in Cloud Security

The covid-19 changed the way we worked as most of the world is either working from home or working in a hybrid model. That being said, now more and more organizations rely on cloud environments as their data storehouse. With the sensitive data lying over the cloud, one of the key security controls these organizations can add is Cloud Data Loss Prevention (DLP) — to identify, monitor, and protect cloud data across your cloud infrastructure

1. Identifying and Protecting Sensitive Data

Data Loss Prevention solutions are used to detect sensitive data within cloud environments. Cloud data loss prevention tools scan and classify data based on predetermined policies that recognize sensitive information (PII, financial records or intellectual property). It is designed to protect cloud data by knowing where data is stored. This categorization process is also critical to ensure data security and prevent unintended exposure or unauthorized access to the storage.

2. Monitoring and Enforcing Security Policies

After data is classified, cloud DLP solutions implement security policies dictating the ways in which this information can be accessed and shared. Sensitive information can easily be mishandled in cloud environment due to multiple users and shared nature of the data. DLP tools constantly track the movement of data and user activities against security policies configured in them. Whenever any suspicious activity and policy violation is identified the cloud data loss prevention systems can automatically raise alerts or even block actions to avoid data spills.

3. Preventing Unauthorized Access

One of the key aspects for DLP in cloud security is stopping unauthorized access to private data. However, cloud environments are more vulnerable to external and insider threats. Cloud data loss prevention solutions can detect abnormal access patterns such as unauthorized users, or suspicious behavior. DLP helps in identifying and controlling data manipulation activities so that the risk of falling prey to such attacks can be reduced.

4. Ensuring Compliance

Organizations using cloud services need to be compliant with various data protection regulations like — GDPR, HIPAA and CCPA etc. Cloud based DLP solutions are instrumental in making sure sensitive data is used within these regulatory lines. This is why DLP helps to keep companies compliant by enforcing policies around how data should be handled and documented, as the risk of leaks or loss increase without it. 

To sum up, Cloud data loss prevention solutions play a critical role in cloud security by providing strong capabilities to discover and classify sensitive data along with monitoring its movement.
