Internet Security

Basically there are five key requirements for choosing the right mobile solution provider consist of:
- Enterprise-class security
- Application optimization with real-time push synchronization
- Broad handheld support and device-level integration
- Robust fleet management tools
- Flexible service and support

Based on research by Motorola group, Wireless access to enterprise information is going mainstream-driven largely by the needs and requests of individual employees within the enterprise. But while the need for wireless access is coming from the bottom up, the management of wireless access needs to be driven from the top down. Otherwise enterprises may find that wireless information access is a complex, chaotic and expensive endeavor with only ambiguous benefits. The key to turning wireless information access into a strategic IT initiative that delivers tangible ROI is developing an enterprise wireless information access strategy.

The widespread area of 802.11 network coverage zones is one of the major reasons for rising security concerns and interest: An attacker can be positioned where no one expects him or her to be and stay well away from the network's physical premises. Another reason is the widespread use of 802.11 networks themselves: By 2006 the number of shipped 802.11-enabled hardware devices is estimated to exceed 40 million units, even as the prices on these units keep falling. After 802.11g products hit the market, the price for many 802.11b client cards dropped to the cost level of 100BaseT Ethernet client cards. Of course there is a great speed disadvantage (5–7 Mbps on 802.11b vs. 100 Mbps on switched fast Ethernet), but not every network has high-speed requirements, and in many cases wireless deployment will be preferable. These cases include old houses in Europe protected as a part of the National Heritage. In such houses, drilling through obstacles to lay the cabling is prohibited by law. Another case is offices positioned on opposite sides of a busy street, highway, or office park. Finally, the last loop provider services via wireless are basically a replacement for the cable or xDSL link and 802.11b "pipe" is not likely to be a bottleneck in such cases, taking into account common xDSL or cable network bandwidth.

Rich Brewer of International Data Corp. (IDC) commented during Directions '99 that "the perception is that most hack attacks come from political activities and professional industrial thieves, but the reality is that approximately 70 percent of attacks come from within a company. Most security breaches are committed through a bunch of holes, enabling hackers to steal assets and, more important, ideas."[Managing a Network Vulnerability Assessment, Thomas R. Peltier, Justin Peltier and John A. Blackley ]

"Hackers are benefiting from a company's silence," Brewer said, adding that "according to the FBI, fewer than 3 percent of hack attacks were detected last year, and out of those, fewer than 1 percent were reported to the FBI." To defend against hack attacks, "products alone can't save" companies.

E-mail spam, also known as "bulk e-mail" or "junk e-mail," is a subset of spam that involves nearly identical messages sent to numerous recipients by e-mail. A common synonym for spam is unsolicited bulk e-mail (UBE). Definitions of spam usually include the aspects that email is unsolicited and sent in bulk.[1][2][3][4][5] "UCE" refers specifically to "unsolicited commercial e-mail."

E-mail spam has existed since the beginning of the Internet, and has grown to about 90 billion messages a day, although about 80% is sent by fewer than 200 spammers. Botnets, virus infected computers, account for about 80% of spam. Laws against spam have been sporadically implemented, with some being opt-out laws and others being opt-in. The total amount of spam has leveled off slightly in recent years. The cost of spam is borne mostly by the recipient, so it is a form of postage due advertising.
