Answer to Question 1

Digital certificates are issued to organizations or individuals by a certification authority (CA). A CA requires entities applying for digital certificates to supply appropriate proof of identity. Once the CA is satisfied, it issues a certificate. Then, the CA signs the certificate, and its stamp of approval is affixed in the form of a public encryption key. The public encryption key unlocks the certificate for anyone who receives the certificate attached to the publishers code. Digital certificates cannot be forged easily.
In effect, the CA guarantees that the individual or organization that presents the certificate is who or what it claims to be.

Answer to Question 2

In 2001, the incidences of virus and worm attacks increased. With more than 40,000 reported security violations occurring that year, the parade of attacks included Code Red and Nimda virusworm combinations, each affecting millions of computers and costing billions of dollars to clean up. Both Code Red and Nimda are examples of a multivector virus, so-called because they can enter a computer system in several different ways (vectors). Even though Microsoft issued security patches that should have stopped the Code Red virusworm, it continued to propagate throughout the Internet in 2002. Both the original Code Red virus and a variant called Code Red 2 infected thousands of new computers during the year.
