AX /10 August 2000 Briefing
Co. AX u u u u u Key Coalition Drivers Supported by the DARPA Co. ABS Program Different doctrine, decision making, rules of engagement and, in general, mission “agendas”. Different technology skill and equipment levels. Different cultures and languages. Questionable compatibility of respective national information systems. Limited models for coalition force operations. Command authorities - agreement and transfers. Variable reliability of components and infrastructures. Information systems resource sharing agreements and capacity. Different interpretation of situational information. Lack of compatible security architectures. From Le. Roy Pearce (Canadian MOD), 1999 Co. AX /10 August 2000 Briefing
Co. AX u u u u Key Technical Drivers Supported by the DARPA Co. ABS Program Working with agents in multiple dynamic domains. Need for partial (secure) sharing and visualization of processes, data and facilities. Need flexible interagent task and process management. Unclear and/or emerging objectives and tasking. Cannot assume compatibility or complete reliability of functional capabilities, communications, security arrangements or information resources. Need to integrate and use legacy systems. Need for rapid formation and management of agent relationships. Need to respect national concerns, limitations, cultural and political differences, etc. Co. AX /10 August 2000 Briefing

Agent Domains Co. AX Supported by the DARPA Co. ABS Program DM An agent domain consists of one or more agents registered with a common Domain Manager which provides for common administration and enforcement of domain-wide, VMspecific, and agent-specific policies. Co. AX /10 August 2000 Briefing
Co. AX u Agent Domain Management in Co. AX Supported by the DARPA Co. ABS Program Broadens typical distributed security concerns to include: u Communication and access management: Who can communicate with whom for what services? u Registration management: Who can join the domain under what circumstances? u Resource management: Who can have which kind and how much of a given computing resource? u Mobility management: Who can move where under what circumstances? u Conversation management: What constraints govern interaction between conversing agents? u Obligation management: Who is not meeting commitments?

Co. AX Policy Enforcement Problems and Solutions Supported by the DARPA Co. ABS Program agents u Problem: Enforcing policies on unmodified, potentially malicious u Solution: Platform-based enforcement (e. g. , Java 2 security) Problem: Permissions granted statically according to code source (can’t have different permissions for two agent instances from same code base) u u Solution: Hack JAAS (Java Authentication and Authorization Service) to allow dynamic permissions and instance-level authentication and authorization u Problem: High-level agent security requirements do not always map to low-level built-in Java security mechanisms u Solution: Lock down permissions of untrusted (agent) code and force agent to use a trusted privileged-code wrapper under control of the guard (eventually to be packaged as domain-aware “grid helper”) to perform selected actions u Problem: Fine-grained resource allocation and control and revocation of permissions in the face of denial-of-service attacks u Solution: Run agent under Java-compatible Aroma VM allowing dynamic fine-grained resource rate and quantity control u Problem: “Obligation policies” cannot be enforced by preventing actions in advance but only by monitoring and after-the-fact sanctions u Solution: Sentinel-based policy enforcement (relevant work in this area by MIT) Co.
