Q . What is Biometric authentication? Biometric authentication uses the biological characteristics of user to authenticate the user. The Biological characteristics that can be authenticated are fingerprints, retina, and voice and so on. Q . What is smart card? A Smart card is pocket sized used for authenticating users. Smart cards store digital information about the user credentials in their Integrated Circuits(IC). Q . What do you understand by Wi-Fi connection? A Wi-Fi connection is used to provide wireless access to local Area Networks (LAN). Q1. Which tasks should be performed to analyze the security requirements of the organization? Ans: - Gather the Business requirements. Identify the business driver for security design. Analyze the management structure of the organiz...
Q. What is SS7 (signaling System 7)? Ans : SS7 (signaling System 7) - signaling is the most widely used signaling system where the signals are transmitted on a separate physical channel from the call channel. Because of that, SS7 network can examine all parts of a call route for free lines and allocate them at once. This leads to a more efficient network and fast call setup times, generally about 3 seconds where as in early CAS systems this might take about 20 seconds. Also it has many more advantages compared to CAS (Channel Associated Signaling) or "in-band" signaling where signals and the call are transmitted on the same channel. SS7 allows telecommunication networks to offer wide ranges of services such as telephony, fax transmission, data transfer, ISDN and IN (Intelligent Networks). SS7 is popular because: SS7 Signaling Types: SS7 supports 2 types of signaling: Circuit related signaling and non-circuit related signaling. Circuit related signa...
