📌 Data Loss Prevention (DLP) Summary

Data Loss Prevention (DLP) refers to a set of tools and processes designed to stop sensitive data from being lost, leaked, or accessed by unauthorised people. It monitors how data is used, moved, and shared within an organisation and outside of it. DLP systems can automatically block, alert, or encrypt data when a risk is detected, helping protect information such as personal details, financial records, or confidential business documents.

🙋🏻‍♂️ Explain Data Loss Prevention (DLP) Simply

Think of DLP like a security guard at the exit of a building, checking that no one walks out with something they are not allowed to take. It makes sure important information stays safe and only goes to people who should have it, just like the guard makes sure only authorised items leave the building.

📅 How Can it be used?

DLP can be set up to monitor outgoing emails in a company, preventing employees from sending confidential files to external addresses.

🗺️ Real World Examples

A hospital uses DLP software to automatically scan emails and file transfers for patient information. If a staff member tries to send medical records outside the hospital network, the DLP system blocks the action and notifies the IT team, ensuring compliance with privacy laws.

A law firm configures its DLP system to prevent employees from copying sensitive case documents to USB drives. If someone tries to move files containing client data to an external device, the system stops the transfer and logs the attempt for review.

✅ FAQ

Data Loss Prevention, or DLP, helps organisations keep sensitive information safe from leaks or unauthorised access. It is important because it protects things like personal information, financial records, and business secrets from getting into the wrong hands, whether by accident or on purpose. This means less risk of data breaches, fines, or damaged reputations.

DLP works by watching how data is used, moved, and shared throughout a company. If it spots something risky, like someone trying to email confidential files outside the business, it can block the action, send an alert, or encrypt the data. This way, it acts like a safety net to catch problems before information can get out.

While DLP is a strong tool for protecting data, it cannot stop every single leak. It can catch most common risks and mistakes, but determined attackers or clever workarounds can sometimes slip through. It is best used alongside other security measures and good staff training to build a stronger defence.

Differential Privacy Guarantees

Differential privacy guarantees are assurances that a data analysis method protects individual privacy by making it difficult to determine whether any one person's information is included in a dataset. These guarantees are based on mathematical definitions that limit how much the results of an analysis can change if a single individual's data is added or removed. The goal is to allow useful insights from data while keeping personal details safe.

Secure Key Storage

Secure key storage refers to the safe keeping of cryptographic keys so that only authorised users or systems can access them. These keys are often used to encrypt or decrypt sensitive information, so protecting them is crucial for maintaining security. Methods for secure key storage can include hardware devices, dedicated software, or secure parts of a computer's memory.

Secure Enclave Encryption

Secure Enclave Encryption refers to a security technology that uses a dedicated hardware component to protect sensitive information, such as passwords or cryptographic keys. This hardware, often called a Secure Enclave, is isolated from the main processor, making it much harder for hackers or malware to access its contents. Devices like smartphones and computers use Secure Enclave Encryption to keep critical data safe, even if the main operating system is compromised.

Encrypted Machine Learning

Encrypted machine learning is a method where data is kept secure and private during the process of training or using machine learning models. This is done by using encryption techniques so that data can be analysed or predictions can be made without ever revealing the raw information. It helps organisations use sensitive information, like medical or financial records, for machine learning without risking privacy breaches.

Private Data Federation

Private Data Federation is a way for different organisations to analyse and share insights from their separate data sets without actually moving or exposing the raw data to each other. This approach uses secure techniques so that each party keeps control of its own information while still being able to collaborate on analysis. It is often used when privacy laws or company policies prevent sharing sensitive data directly.
