Data loss can cause tremendous damage to a business. It diminishes trust in your brand and can lead to financial losses from lawsuits, fines for non-compliance, and theft of intellectual property.
Data loss prevention (DLP) is the set of practices and tools designed to prevent data leakage through intentional and unintentional misuse. These practices and tools include encryption, detection, preventative measures, educational pop-ups, and even machine learning to identify vulnerabilities.
Over time, DLP has become a core part of data protection. Although the DLP market is not new, it has grown to encompass managed services, cloud capabilities, and enhanced threat protection. All of this, combined with the rising number of data breaches, has resulted in a tremendous surge in the use of DLP to protect sensitive data.
The cloud can help with DLP, but cloud security is a vast topic that can mean different things to different organizations. Broadly speaking, cloud security is how an organization applies cybersecurity to the technology and business processes it runs through cloud services. Cloud data loss prevention is one of the top goals when managing risks with cloud storage.
Cloud DLP solutions help keep an organization’s sensitive or critical information safe from cyberattacks, insider threats, and accidental exposure.
The Benefits of Using the Cloud for Data Loss Prevention
Cloud ecosystems allow employees to access files remotely and work anywhere. Although the cloud does help productivity, there’s always a risk that employees will use unapproved cloud storage and cloud apps, known as shadow IT. Organizations must protect sensitive data on their networks by providing vetted cloud services for their employees.
If your organization stores data or communicates via software-as-a-service applications in the cloud, you need cloud DLP. Using DLP in the cloud brings many advantages over perimeter-based security. DLP solutions help to implement measures that prevent and mitigate the risks associated with shadow IT.
DLP in the cloud provides other benefits, too:
Secure Integration
DLP can help assure secure integration with cloud storage providers. This activity includes scanning servers’ controls, identifying sensitive data, and encrypting the information before the file is shared in the cloud.
Deep integration with cloud applications such as G Suite and Office 365 via an application programming interface (API) makes it a near-native security feature of your team’s applications.
Continuous Scanning and Auditing
Another benefit is the ability to audit existing data and classify it into established categories of sensitivity and protection. DLP enables organizations to scan data in cloud storage and audit the data continuously, including in uploaded files.
Automated Policies
DLP tools provide capabilities to automate enterprise policies that apply controls to sensitive data. Users can receive warnings, or specific actions can be blocked. Tools can automatically encrypt sensitive data before it is stored or transferred.
Instant Alerting
Between lack of awareness, unintentional user actions, system failures, and increasingly sophisticated malicious activity, there is a risk of sensitive data being exposed. DLP solutions have built-in alerts that allow administrators and stakeholders to receive immediate warnings when data is potentially compromised.
Maintaining Visibility
When users disconnect from their networks and connect straight to the cloud, they can circumvent gateway security protections. This can create a security gap, allowing critical data to transit outside their network.
Most DLP tools provide capabilities to ensure visibility and control within cloud ecosystems. These controls are necessary for organizations to comply with data privacy and protection regulations.
Regulatory Compliance
Various data protection regulations require you to implement measures to protect sensitive information on your network from unauthorized persons. Some of these include the Health Insurance Portability and Accountability Act (HIPAA), Payment Card Industry Data Security Standards (PCI DSS), and the European Union’s General Data Protection Regulations (GDPR).
Using the cloud for DLP can streamline your data protection activities and compliance with legal requirements.
Tips for Using Cloud Data Loss Prevention
Several techniques can help improve your cloud implementation and DLP efforts. Here are some best practices to assure that essential tasks are performed to prevent data loss in the cloud.
Prioritize Data
Not all data is equally important. Therefore, data loss prevention efforts do not need to be applied equally to all data and file types across the cloud. Determine which data would create the most serious problems if taken and which data is most likely to be targeted by attackers.
Classify Sensitive Data
Further classify sensitive data by putting it into categories such as “important,” “confidential,” “private,” and “sensitive.” Pre-configured regulations already exist for credit card numbers, Social Security numbers, and other personally identifiable information (PII).
Cloud DLP policies tag data into categories to help administrators locate and evaluate batches of data for proper security controls.
Monitor Data in Motion
Organizations should monitor data in motion among internal users and external third parties. This will help the business understand how sensitive data is processed and assess the scope of any issues that need to be addressed by the cloud-based DLP approach.
Communicate and Develop Controls
At first, controls will target common behaviors that seem relatively intuitive. As the cloud DLP program evolves, organizations can implement more fine-tuned controls to reduce advanced hazards. Cloud-access security brokers (CASBs) allow you to apply more granular restrictions by combining context and content (data classification).
Train Your Employees
You can reduce insider data loss by training users on security policies and common social engineering scams, such as phishing attempts. Employees are often unaware that their activities can result in data loss. If they are informed, they will make better decisions on their own.
