The IAVM Notices are posted on a USCYBERCOM website and also entered into the Defense Information Systems Agency (DISA) operated Vulnerability Management System (VMS). IAVM is an acronym, which means Information Assurance Vulnerability Management. The IAVM publishes three types of alerts: IA Vulnerability Alerts (IAVA) address severe network vulnerabilities resulting in immediate and potentially severe…

Services that are not bound to a certain layer but may have an impact on multiple layers are known as cross-layer functions. All of the levels are involved in some orthogonal issues, such management and security. The confidentiality, integrity, and availability of the sent data are improved by these services. In reality, cross-layer functions are…

Cross-layer functions are services that are not tied to a given layer but may affect more than one layer. Some orthogonal aspects, such as management and security, involve all of the layers. These services are aimed at improving the CIA triad—confidentiality, integrity, and availability—of the transmitted data. Cross-layer functions are the norm, in practice, because…

The 7 layers of the OSI model describe how computer systems communicate over a network. Understanding the functions and responsibilities of each layer will help you understand how network communications function. The development of the OSI model started in the late 1970s to support the emergence of diverse computer networking methods, such as the current…
