Information protection issues related to the Future of the Internet: Four areas of particular concern today and for the future of information protection in the Internet are; (1) the ability to audit and trace activities to their source, (2) the ability to assure the integrity of information entering, passing through, and coming out of this network, (3) the ability to test and control the infrastructure so as to assure the availability of services and propriety of configurations, and (4) the ability to detect and properly respond to suspected and actual intrusions. 1) The ability to audit and trace activities to their source: Today's Internet and the current protocols for the next generation of the Internet have no provision for tracing information passing through the infrastructure. As a result, (1) we have widescale IP address forgery, (2) we are often unable to trace an attack back to it's source, and (3) we cannot normally assure that information entering our facilities are from the sources they claim to be from. One option we now have is adding cryptographic countermeasures that are (1) not uniformly permitted due to export restrictions, (2) optional add-ins under today's protocol specification, (3) have high-cost, (4) reduce performance, (5) do not provide a mechanism for auditing, and (6) make tracing of some activities harder by obscuring the very information that could otherwise be used for tracability. To address these issues, research is required into how we can trace and audit activities without undue bandwidth and performance reduction. With proper audit mechanisms, the sources of most detected attacks could be traced and people could be held accontable for their actions. 2) The ability to assure the integrity of information entering, passing through, and coming out of this network: In today's Internet, there is effectively no integrity control. As a result, we have (1) widescale email forgery, ongoing attacks against the integrity of servers and clients, (2) browser-based attacks that bypass firewalls and similar controls, (3) server attacks that succeed in corrupting information in federal agencies as well as throughout the private sector, (4) infrastructure attacks that have redirected routing at the very core of the Internet's domain name services, and (5) buffer overflow attacks that threaten almost every kind of system in use today. In order for the Internet to become truly viable for carying critical information during serious disruptive attacks, it is vital to provide the means to have assured integrity of critical pieces of information and of the infrastructure on which we depend. Research is needed in order to find and test viable methods for attaining integrity without otherwise disrupting the operations of the Internet. 3) The ability to test and control the infrastructure so as to assure the availability of services and propriety of configurations: In today's Internet, router misconfiguration, Domain Name Service errors, and protocol deficiencies cause large scale outages, poor performance, and unnecessarily high costs. Most large organizations with substantial Internet or intranet connectivity have employees spending much of their time in manually figuring out how to configure the infrastructure, manually entering configuration commands, and asking users to try things in order to determine what is working. Research is needed in order to find methods that will permit automated and efficient, analysis, configuration, and verification of infrastructure elements. The results of such work will include reduced in network costs, increased efficiency, reduced downtime, and increased assurance of information infrastructure. 4) The ability to detect and properly respond to suspected and actual intrusions: In today's Internet, intrusions go largely undetected, and response to detected intrusions are typically limited to beeping a person, sending email, shutting down access, or similar activities. In addition to the well-known inability to detect many attacks and the reflexive control implications of these sorts of responses on those who use them, there are many unanswered questions in the field of intrusion detection and response that are not being addressed by current research or development efforts. Research is needed in order to identify the key issues in intrusion detection, to address the mathematical underpinnings of this field, to experiment with schemes that address differing organizational resuirements, and to tailor detection and response to the organization's work flow. In addition to the positive impact research in these areas will have on information protection, they also contribute to stability, improved performance, and lower cost of operation, and as such, have a positive impact on the cost effectiveness of the Internet both for government and private sector use. --- Fred Cohen can be reached at tel:510-294-2087 fax:510-294-1225
