Information Systems
As Information Systems (IS) development becomes more a function of purchasing packages or assembling components, with less emphasis on programming, student enrollment in IS courses at universities continues to decline.
Sometimes it looks like the IT revolution has moved on and left many IS researchers [ADVERB].
For example, according to Nokia, the next generation of computers will be in your pocket. About 1.3 billion mobile phones are sold each year, compared to only 300 million personal computers. An increasing number of these phones come with full-blown operating systems that let users access, organize, and use much more information than older handhelds. The mobile software market may soon exceed the current software market for computers, and a wide variety of information systems will rise on top of all the new software. However, only a relatively small percentage of IS research focuses on the mobile revolution.
Actually, many IS programs in business colleges seem impervious to the wake-up call that information schools provide. Rather, they continue to offer curricula that reflect the past rather than look toward the future. Little wonder that students, whose degrees are based on a very limited number of traditional courses in one area of study, often fail to meet their employers’ expectations. With little integration across disciplines to prepare students for the complex problems they will face, organizations find it necessary to further educate those whom they hire or go abroad to seek appropriate employees with a wider range of skills and knowledge.

E-mail Spoofing
E-mail spoofing is the forgery of an e-mail header so that the message appears to have originated from someone or somewhere other than the actual source. Distributors of spam often use spoofing in an attempt to get recipients to open, and possibly even respond to, their solicitations. Spoofing can be used legitimately. However, spoofing anyone other than yourself is illegal in some jurisdictions.
E-mail spoofing is possible because Simple Mail Transfer Protocol (SMTP), the main protocol used in sending e-mail, does not include an authentication mechanism. Although an SMTP service extension (specified in IETF RFC 2554) allows an SMTP client to negotiate a security level with a mail
server, this precaution is not often taken. If the precaution is not taken, anyone with the requisite knowledge can connect to the server and use it to send messages. To send spoofed e-mail, senders insert commands in headers that will alter message information. It is possible to send a message that
appears to be from anyone, anywhere, saying whatever the sender wants it to say. Thus, someone could send spoofed e-mail that appears to be from you with a message that you didn't write.
Although most spoofed e-mail falls into the “nuisance" category and requires little action other than deletion, the more malicious varieties can cause serious problems and security risks. For example, spoofed e-mail may purport to be from someone in a position of authority, asking for sensitive data, such as passwords, credit card numbers, or other personal information – any of which can be used for a variety of criminal purposes. One type of e-mail spoofing, self- sending spam, involves messages that appear to be both to and from the recipient.
