Data protection at the transport layer

Common Threats to Data at the Transport Layer

• Data transmitted over the transport layer is vulnerable to a range of threats that can compromise its confidentiality, integrity, and availability. Here are some of the most common threats to data at the transport layer:
• Interception: This occurs when an attacker intercepts data as it is being transmitted between network hosts. The attacker can then read, copy, or modify the data. Interception can be carried out using various techniques such as packet sniffing, man-in-the-middle attacks, or session hijacking.
• Eavesdropping: This involves listening in on the communication between network hosts without their knowledge or consent. Eavesdropping can be carried out using devices such as wireless sniffers or compromised network equipment.
• Data tampering: This involves modifying the data as it is being transmitted between network hosts. Data tampering can be used to modify the content of a message, or to inject malicious code or malware.
• The consequences of these attacks can be severe for individuals and organizations. Interception and eavesdropping can result in the compromise of sensitive information such as personal or financial data

Interception

• Interception is a common threat to data at the transport layer. It occurs when an attacker intercepts and steals data as it is transmitted over the network. This can be done by capturing the data packets in transit or by compromising the network infrastructure.
• The consequences of interception can be severe. Attackers can use intercepted data for various malicious purposes, including identity theft, financial fraud, or reputational damage. Moreover, organizations may face legal or financial penalties for failing to protect their customers' data.
• To prevent interception, it's crucial to use encryption techniques such as TLS, which encrypts data in transit and protects it from being read or modified by unauthorized parties. It's also important to avoid using unsecured public Wi-Fi networks, which can easily be intercepted by attackers.
