A significant improvement upon DES' 56-bit key support, AES supports key sizes of 128 bits, 192 bits, and 256 bits. IPSec enables secure packet transmission over shared networks. Although broadband Video Communications: The Whole Picture access is making the Internet more viable for video communication, VPN encryption and decryption latency can be an impediment. However, it is clear that, as processors become faster, codecs become more sophisticated, and QoS techniques become more reliable, VPN based video communication will become common. SECURITY: WHERE TO START In its 2004 Global Information Security Survey, CIO Magazine, CSO Magazine, and PriceWaterhouse Coopers found that organizations that followed a best-practices approach to information security suffered more security incidents, but experienced less downtime and fewer financial losses. The study found that group to spend more on information security as a percentage of its IT budget, and to measure or review its own effectiveness more. It also found it to be more likely to integrate information security with physical security, to have more employees who are likely to comply with security policies, and to provide more reinforcement for information security efforts from top-level executives. CIO Magazine interpreted the survey with a short-list of six practices that make the best-practices group more successful than the rest. First, it found the group to spend 14% of IT budgets on information security, in contrast with the overall average of 11%. Second, it found the group to have group information security with physical security rather than with IT. Third, it found the group to be 60% more likely to be current in software patching and more likely to have conducted a thorough threat analysis. Fourth, it found the group to be 50% more likely to have classified threats and vulnerabilities in the context of a risk assessment. Fifth, it found that more than 65
