📌 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.

💡Other Useful Knowledge Cards

Content Curator Engine

A Content Curator Engine is a software system that automatically gathers, organises, and presents digital content from various sources based on specific topics or criteria. It uses algorithms to filter and select relevant articles, videos, images, and other media, making it easier for users to find quality information without searching manually. These engines are often used by businesses, educators, and media platforms to keep their audiences updated with fresh and relevant content.

Certificate Pinning

Certificate pinning is a security technique used to ensure that a website or app only communicates with trusted servers. It works by storing a copy of the server's digital certificate or public key within the app or client. When the app connects to a server, it checks that the server's certificate matches the stored one. If it does not match, the connection is blocked, preventing attackers from using fake certificates to intercept or alter communications.

File Integrity Monitoring (FIM)

File Integrity Monitoring (FIM) is a security process that checks and tracks changes to files on a computer system or network. It helps ensure that important files, such as system configurations or sensitive data, are not changed without authorisation. FIM tools alert administrators if files are modified, deleted, or added unexpectedly, helping to detect potential security breaches or unauthorised activity.

Token Distribution Models

Token distribution models describe the ways digital tokens are allocated to users, investors, team members or the public in blockchain and cryptocurrency projects. These models determine who receives tokens, how many they get, and when they are distributed. Choices about distribution can affect a project's fairness, funding, security and long-term success.

AI for Tokenomics Design

AI for tokenomics design refers to using artificial intelligence to help create, analyse, and optimise the economic systems behind digital tokens. Tokenomics covers how tokens are distributed, how they gain value, and how people interact with them in a digital ecosystem. By using AI, designers can simulate different scenarios, predict user behaviour, and quickly identify potential issues in the token system.
