Introduction to Data Protection

• Data protection refers to the measures taken to safeguard data against unauthorized access, use, disclosure, modification, or destruction. In today's digital age, data is one of the most valuable assets for individuals and organizations. Protecting data is crucial to maintain privacy, confidentiality, integrity, and availability of information.
• There are various types of data that need to be protected, such as personal information, financial data, and intellectual property. Personal information includes names, addresses, phone numbers, email addresses, and other identifiable information. Financial data includes credit card numbers, bank account details, and other financial information. Intellectual property includes trade secrets, patents, trademarks, and copyrights.

Understanding the Transport Layer

• The transport layer is a layer in the OSI (Open Systems Interconnection) model and is responsible for transmitting data between different network hosts. The main function of this layer is to ensure that data is delivered reliably and securely.
• The transport layer is responsible for breaking data into segments and reassembling them at the receiving end. This ensures that the data is transmitted in an efficient manner and can be reassembled in the correct order. The transport layer also provides flow control and error correction to ensure that data is delivered without any loss or corruption.

Understanding the Transport Layer

• There are two main protocols used at the transport layer: Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). TCP is a reliable protocol that provides error checking and flow control. UDP is a faster protocol that does not provide error checking or flow control.
• To ensure that data is delivered securely, the transport layer can use encryption techniques such as Secure Sockets Layer (SSL) or Transport Layer Security (TLS). These techniques provide a secure channel for data to be transmitted and prevent unauthorized access or interception of data.
