Data Loss Prevention (DLP) ensures that confidential or sensitive data is not lost, stolen or inadvertently distributed. It can be used to prevent data breaches and protect an organization’s reputation.
You may have heard about DLP in the news, but what exactly is it? And how can you use it to protect your data?
What is Data Loss Prevention (DLP)?
Data loss prevention (DLP), also known as data leak prevention, is the practice of identifying, monitoring, and protecting sensitive information. This may include social security numbers, credit card information, or trade secrets.
DLP is used to prevent accidental leakage of this information as well as malicious attacks designed to steal it.
This is important because if this information falls into the wrong hands, cyber criminals can use it for identity theft, fraud, or other malicious activities. Typically, it involves using a combination of technologies, including data encryption, activity monitoring, and user education.
That being said, many organizations use DLP to protect their personally identifiable information (PII) and private business information to ensure compliance with industry and privacy standards.
Let’s say you work from home or in a Bring Your Own Device (BYOD) organization. In this case, your organization can use DLP techniques to protect its sensitive data on your device.
How does Data Loss Prevention work?
DLP technology works in several ways.
First, it can be used to identify sensitive data. It usually does this by looking for specific patterns or keywords in files and emails. Once this data is identified, DLP can be used to monitor how it is used and shared.
This can include tracking who is accessing the data, what they are doing with it and where it is being sent.
Businesses can also use DLP to prevent sensitive data from being shared in unauthorized ways. For example, some DLP solutions can prevent emails containing sensitive information from being sent to personal email accounts. Others may encrypt files containing sensitive data so only authorized users can open them.
Apart from that, as a business owner, by using DLP you can also prevent your employees from reading or writing from a USB drive. This prevents unauthorized transmission of data.
And when it comes to detection, business owners can use the DLP application to monitor inbound emails for suspicious attachments or phishing links.
The 3 types of DLP solutions
There are a few different types of DLP solutions, each with their own advantages and disadvantages.
1. On-premises DLP solutions
Some companies choose to install DLP software on their servers and workstations. This allows them to monitor all activity on those devices and identify any sensitive data that is being accessed or shared. Such DLP solutions are known as on-premise DLP. They offer the highest level of control and visibility, but can be complex to deploy and manage.
2. Network-based DLP solutions
Organizations choose to deploy DLP sensors at key points in their network, such as: B. E-mail servers or Internet gateways. This allows them to monitor traffic for sensitive data sent outside of the organization. Network-based DLP solutions are typically easier to deploy than on-premises solutions, but offer less insight into what is happening on individual devices.
3. Cloud-based DLP solutions
Finally, some DLP solutions are cloud-based and delivered as a service. They can be used to monitor activity across the organization, regardless of where the data is stored or how it is accessed. These solutions are typically the easiest to deploy, but may not provide the same level of control and visibility as on-premises solutions.
Why is data loss prevention important?
Data loss can have serious consequences for both individuals and organizations.
Identity theft can result in financial loss and damage your reputation. A data breach can damage your company’s reputation and result in hefty fines. By using DLP, you can help prevent these events from occurring.
DLP can also help you meet compliance requirements such as those set out in the EU’s General Data Protection Regulation (GDPR).
According to the GDPR, companies must take measures to protect the personal data of their customers and employees. This also includes ensuring that this data is only accessed and used by authorized persons. Non-compliance with the GDPR can result in large fines.
DLP can also help you meet Payment Card Industry Data Security Standard (PCI DSS) requirements. This standard requires organizations that process credit card payments to take steps to protect that data from access or theft.
Apart from that, data loss prevention is important as it can help protect your company’s trade secrets and other sensitive information. Your competitors could use this information to gain an advantage over you. By using DLP, you can ensure that only authorized individuals access and use this information.
Best practices for data loss prevention
There are some best practices you can follow to protect your data:
- Encrypt your files: One of the best ways to protect your data is with encryption. This makes it unreadable if it falls into the wrong hands.
- Train your employees: It is important to train your employees on how to handle sensitive data. They should know how to spot it and what to do when they come across it.
- Monitor your network: You should monitor your network for suspicious activity. This helps you detect unauthorized access to your data.
- Implement a DLP solution: A DLP solution can help you protect your data by identifying, monitoring, and preventing unauthorized disclosure of sensitive information.
Why should you choose DLP for your business?
DLP technology is constantly evolving and new solutions are constantly being developed. As organizations realize the need to protect their sensitive data, DLP is becoming an increasingly popular solution.
DLP is an essential tool for any business or individual that wants to protect their data. It can help prevent data loss, meet compliance requirements, and protect your reputation. Follow data loss prevention best practices to protect your data.
