Question

Explain in at least a paragraph

• What are the risks associated with a pervasive security infrastructure?
• What are the reasons for NOT having such infrastructure?
• What are the alternatives?

Answer 1

In the context of network security, As the name suggests that the pervasive infrastructure is where the resources are shared among the group in a network. For example, In a network, at the physical layer, a physical medium is shared among people in a wired or wireless network. If security architecture is too werak then it can affect the data link layer and network layer too. There are too many risks using this architecture like congestion in the network, some users request the same server a time. While a server can serve all request at the same time but the pervasive infrastructure is unable to send the responses at the same time because of congestion which will lead to Denial of Service. Another risk is related to network security. Since the resources are shared so the same security architecture is shared among all the users. So the eavesdropping at a local access point can lead to high risk in security. Any hacker can grab such kind of eavesdropping in the network using a local access point. These are the reasons why pervasive infrastructure is not preferred. The Alternatives to pervasive infrastructure could be Nomadic and Ubiquitous infrastructure. In Nomadic infrastructure, the networks are about to plug and play type where randomness is very high, while in ubiquitous infrastructure, the security is based on global access.
