IP Telephony is Unsafe. The reality is that security attacks are rare for IP telephony. Preventive measures for securing an IP telephony environment are very similar to securing a data-only environment. IP telephony eavesdropping is the most over-hyped threat. Eavesdropping is unlikely to happen since it requires local area network (LAN)-based access to the intranet. The attackers must be inside the company because they have to be on the same LAN as the IP telephone that is subject to the eavesdropping attack.
Gartner analysts said companies can encrypt voice traffic to protect IP telephony eavesdropping, but typically it is not required. It is no more difficult to eavesdrop on voice packets than it is on data packets.
"Enterprises that diligently use security best practices to protect their IP telephony servers should not let these threats derail their plans," Mr. Orans said. "For these enterprises, the benefits of IP telephony far outweigh any security risks."
Mobile Malware Will Cause Widespread Damage. In most cases, mobile malware will be a niche nuisance in the foreseeable future. Penetration of smartphone and personal digital assistants (PDAs) with always-on wireless to knowledge workers or consumers was about 3 percent in 2005. Gartner projects it to reach approximately 10 percent by the end of 2005.
"Anti-virus vendors see huge potential profit opportunities in selling security solutions to billions of cell phone and PDA users," Mr. Pescatore said. "In particular, the anti-viral industry sees cell phones as the way to grow sales outside of a flat, commoditized PC market. However, device-side anti-viruses for cell phones will be completely ineffective."
"The most effective approach to blocking mobile malware will be to block it in the network," Mr. Pescatore said. "Companies should ask their wireless service providers to document existing and planned capabilities. By the end of 2006, all wireless service providers should be required to offer over-the-air mobile malware protection."
"Warhol Worms" will Make the Internet Unreliable for Business Traffic and VPNs. A "Warhol Worm" is a worm that infects all vulnerable machines on the Internet within 15 minutes. The "SQL Slammer" worm had a strong impact on the Internet in 2003, but this is the only observed example of a "Warhol Worm."
Gartner analysts project that through 2007, the Internet will meet performance and security requirements for all business-to-consumer traffic, 70 percent of business-to-business traffic and more than half of corporate wide area network (WAN) traffic.
"Every organization should consider using Internet VPNs, and most should adopt them in some way," said Mr. Orans. "Today's Internet offers a low-cost, good-enough or better option to the data networks of traditional global carriers."
Regulatory Compliance Equals Security. Regulations often provide a means to obtain funding for important security initiatives before incidents occur, but most regulations lead to increased reporting rather than increased levels of security.
"Regulations generally take more static looks at issues and generally don?t lead to higher levels of security in proportion to the spending required to meet the latter of the law," Mr. Orans said. "The best way to increase enterprise IT security is to buy and build software that has fewer vulnerabilities, but there has been no regulatory focus on this area. Companies should focus on building stronger security processes, then document these processes to demonstrate regulatory compliance."
Wireless Hot Spots Are Unsafe. Uneducated consumers can fall prey to wireless hackers, but enterprises can equip and educate their mobile workers with the tools and knowledge to mitigate these threats and increase business productivity via hot spot usage.
Gartner analysts said mobile users should seek out 802.1X protected access points because these points facilitate encryption between the mobile endpoint and the access point. Users can also use client-based software, such as solutions from AirDefense, AirMagnet or T-Mobile?s Connection Manager, that can validate the access point?s identity and thereby reduce the risk of connecting to a hacker?s access point.
"Mobile uses in hot spots should utilize their corporate VPN connection to protect traffic as it travels through the Internet," Mr. Pescatore said. "Mobile users in hotspots should use personal firewalls and turn off file/print sharing to protect their endpoints from data theft."
