The information security goal won't change - companies will continue to need to protect corporate resources and ensure the integrity of their business transactions. But many factors will raise the stakes and make security technologies even more pervasive and essential. The expansion of collaboration and the rising volume of business transactions over the Web will make trust more important than ever. Organizations will place a greater emphasis on robust authentication and authorization and strong encryption, and they'll use PKI and other authentication technologies to help create a secure and trusted communications infrastructure. Clients and servers alike will be expected to prove they're who they say they are and can be trusted, i.e., don't have malicious code. Web services depend on the ability to validate the integrity of the code being downloaded, so code signing with digital certificates will become the norm. Wireless networks will take on more robust encryption and protocols to foil electronic eavesdroppers. Emerging technologies such as biometric identification will offer new opportunities to ensure secure access to confidential resources. Above all, companies will become more deeply aware that information security must be an integrated management discipline, not a piecemeal solution.
