Unmasking OSI Layers: How Cyber Attacks Target Each Level
The Open Systems Interconnection (OSI) model serves as the blueprint for network communication, breaking down the process into seven distinct layers. While these layers facilitate seamless data exchange, they can also become vulnerabilities when exploited by cybercriminals. In this blog post, we'll explore each OSI layer and shed light on how cyber attacks can target and compromise the integrity, confidentiality, and availability of data. Physical Layer: The physical layer deals with the actual transmission of raw bits over physical media. While not directly targeted by cyber attacks, its vulnerabilities can be exploited. Attackers may physically tamper with cables or equipment, causing network disruptions or eavesdropping. Data Link Layer: The data link layer ensures error-free transmission between directly connected devices. MAC address spoofing is a common attack here, where attackers manipulate MAC addresses to gain unauthorized access to a network, known as a "man-in-the-...
