Network security concepts Network security starts with authenticating‚ commonly with a username and a password. Since this requires just one detail authenticating the user name —i.e. the password— this is sometimes termed one-factor authentication. With two-factor authentication‚ something the user ’has’ is also used (e.g. a security token or ’dongle’‚ an ATM card‚ or a mobile phone); and with three-factor authentication‚ something the user ’is’ is also used (e.g. a fingerprint or retinal scan)

Network Consultant Scenario IT 240 July 1st‚ 2011 Network Consultant Scenario The answer I selected was C‚ because solution that was proposed does not achieve the required results but does achieve one of the optional results. CAT 5 UTP cables being installed to the current networks will not satisfy the any of the results required or optional. The hub should be replaced by a switch which can support the speeds that some of the equipment can handle in this case is upwards of 100 mbps due

Introduction If you’ve ever been a network administrator‚ the call you dread the most might be one you receive in the middle of the night by some panicked employee stating that a portion of your critical network has gone down. What troubleshooting options are available to provide answers to your network problem? Besides having a proactive helpdesk that can "read" the mind of your network‚ an important part of troubleshooting involves using a network protocol analyzer. If you’ve done your research

Carrier Sense Multiple Access with Collision Avoidance. However‚ simple CSMA is susceptible to the hidden node problem‚ especially in so called ad hoc networks where a node may communicate directly with every other node in range or using intermediate nodes as relays otherwise. Hidden nodes cause costly packet collisions and thus significantly affect network performance. In order to combat the hidden node problem‚ a mechanism known as Request to Send/Clear to Send (RTS/CTS) handshake is often used. RTS/CTS
