After reading data from the card, the voter is asked to give his fingerprint which must match with the fingerprint stored in the national database. A voter can see the list of candidates after passing the authentication step. Then s/he can choose only one candidate from the list whom s/he wants to vote for.

When using an automated teller machine (ATM), it is imperative that you observe and strictly comply with the following safety procedures.A computer virus is a little piece of software that travels from one computer to another and causes problems with its functioning. A computer virus may damage or remove data on a computer, distribute the virus to other computers through email, or even wipe the hard drive clean. Computer infections are often propagated via email attachments or instant messaging conversations. As a result, you should never open an email attachment unless you know who sent it or unless you are expecting it. Viruses might be camouflaged as comical photos, greeting cards, or audio and video files in email attachments. Computer viruses may also be propagated through Internet downloads. They may be found in pirated software, as well as other files and applications that you may download. Why would designers place software inside the kernel (or make use of kernel software) if it is so dangerous? What additional strategies do you use to avoid viruses if you were an antivirus creator or maker?

What are your plans for the future?Identifying New Computer Viruses and Worms Objective: Examine some current computer virus threats. Description: As a security professional, you must keep abreast of the manynew viruses and worms that might attack networks and computers. If one computer is compromised, all computers in your network could be compromised.

Remember, a firewall doesn't examine packets internal to the network, so malware can spread internally in an organization regardless of how effective the firewall is. A good place to learn about new threats is the Internet. 1. Start your Webbrowser, and go to www.us-cert.gov. 2.
