REN-ISAC Research and Education Networking Information Sharing and Analysis Center

1. REN-ISACResearch and Education Networking Information Sharing and Analysis Center Internet2 Member’s Meeting Chicago 5 December 2006

2. ISACs • The development of Information Sharing and Analysis Centers (ISACs) was encouraged by U.S. Government Presidential Decision Directive 63: Protecting America's Critical Infrastructures (1998), to • gather information on vulnerabilities, threats, intrusions, and anomalies; • perform analysis and develop recommended response; • and disseminate information so that member organizations can better defend and secure their infrastructures and operations.

3. ISACs • Subsequently, The National Strategy to Secure Cyberspace (2003) states: "The National Cyberspace Security Response System is a public-private architecture, coordinated by the Department of Homeland Security, for analyzing and warning; managing incidents of national significance; promoting continuity in government systems and private sector infrastructures; and increasing information sharing across and between organizations to improve cyberspace security. The National Cyberspace Security Response System will include governmental entities and nongovernmental entities, such as private sector information sharing and analysis centers (ISACs)."

4. ISACs • Collect, derive, analyze, and disseminate security threat information, including: • the physical security of infrastructure, operations, and facilities, and • computing and networking infrastructures • Provide resources to support member understanding of threats, protection, and mitigation techniques • Most, including REN-ISAC, are private-sector entities

6. REN-ISAC • Is an integral part of U.S. higher education’s strategy to improve network security through information collection, analysis, dissemination, early warning, and response; • is specifically designed to support the unique environment and needs of organizations connected to served higher education and research networks; and • supports efforts to protect the U.S. national cyber infrastructure by participating in the formal ISAC structure.

7. REN-ISAC • Membership is open and free to institutions of higher education, teaching hospitals, research and education network providers, and government-funded research organizations. • http://www.ren-isac.net/membership.html

16. Trust Community for R&E Cybersecurity • A trusted community for sharing sensitive information regarding cybersecurity threat, incidents, response, and protection, specifically designed to support the unique environment and needs of higher education and research organizations. • Membership is oriented to permanent staff with organization-wide responsibility for cybersecurity protection or response at an institution of higher education, teaching hospital, research and education network provider, or government-funded research organization. • http://www.ren-isac.net/membership.html

17. Information Sources • Network instrumentation and sensors • Abilene netflow • Arbor Networks Peakflow SP • Darknet, honeypots • Global NOC operational monitoring systems • Direct reconnaissance • Information sharing relationships • Private network security collaborations • Members • Daily security status calls with ISACs and US-CERT • Backbone network and security engineers • Vendors, relationships and monthly ISAC conferences • Relationships to national CERTs

18. Information Products • Daily Weather Report provides situational awareness and actionable protection information. • Alerts provide critical, timely, actionable protection information concerning new or increasing threat. • Notifications identify specific sources and targets of active threat or incident involving member networks. • Threat Information Resources provide information regarding known active sources of threat. • Advisories inform regarding specific practices or approaches that can improve security posture. • Instruction on technical topics relevant to security protection and response. • Monitoring views provide aggregate information for situational awareness.

19.

20. Additional Works in Progress • Regional Security Groups • Facilitate organizational interactions of regional security working groups, particularly aimed to assist new/developing groups. • Vendor relationships • Serve as a two-way interface for deep relations between vendor security teams and U.S. higher education. • Internet2 Abilene Operational security exercises • First held November 2005: • Day-long “table top” exercise (talking only, no flows) • Abilene backbone infrastructure attacks, 2 scenarios • Report identifies ~40 observations • Second (date TBD) will include domestic and international participants

21. Additional Works Under Consideration • Additional Threat Information Resources • Malware sites • Warez IRC networks • Clearinghouse for additional information resources • Snort signatures • IDS and firewall logs, netflow, darknet, etc. • Passive DNS Replication • Collect limited information from participating institution DNS systems to develop a database that can be used to perform reverse queries to identify the domain name miscreants use in conjunction with identified hacked or infected machines.

22. Additional Works Under Consideration • Bro IDS on a backbone network • Open-source network intrusion detection system. Passively monitors for suspicious traffic by comparing against rules describing events or patterns • Developed at Lawrence Berkeley National Laboratory • Designed for use at institutional network borders or choke points; potential value in inter-network backbones(?) • Areas for exploration: • Use on 10 Gbps links • Direct network anomaly detection and response • Botnet command and control identification • Worms and malware • BGP analysis • Live fingerprint sharing in community of Bros • Policy considerations for the use of packet inspection on backbone networks

23. Additional Works Under Consideration • HoneyFarm via GRE • A honeypot is a system that interacts with an attacker and pretends to be a victim. It logs the attack activity and may permit itself to be compromised, thereby recording the attack method and capturing sample of the installed malware. A honeynet is an architected system and network of computers designed to be attacked. • Project to deploy a large central honeynet managed by REN-ISAC in cooperation with the IU Advanced Network Management Laboratory. Address space is contributed by REN-ISAC members, and tunneled to the honeyfarm via GRE across Abilene.

24. Additional Works Under Consideration • Inter-organizational incident tracking system • Use of IODEF. Being looked at by SALSA CSI2 • Malware sandbox

25. R&D Opportunities • Security considerations for regional, national, and global layer 1 & 2 networks • L1 and L2 interconnections acquired and controlled by end-users, for example big science research projects, can introduce unexpected, uncontrolled, and unstable network topology elements and circumvent campus security borders – potentially affecting an entire campus. Dynamic interconnection provisioning amplifies the risk. • Need shared knowledge in a closed security community of the dynamic end-to-end lambda and L2 interconnection assignments • Who is my university connected to today?

26. R&D Opportunities • Packet inspection tools on high-speed networks • Statistical methods to identify departures from normal variation and anomaly detection to identify botnets, worms, and other infections • Netflow, darknet, IDS, and other data sources • Expand monitoring methods and instrumentation – other R&D opportunities • IPv6 • Multicast • BGP health • SPAM load • Instant Messaging threat vectors

27. Relationship Opportunities • International relationships for R&E network security protection and incident response • Potential areas for cooperation • Shared Darknet Project • Information sharing regarding active botnets, malware sites, etc. • Cooperation on DDoS trace back; Arbor FP sharing • L1/L2 security considerations • Bro on the Backbone experiment • Facilitate notifications to security contacts at source institutions for botnet and other incidents • Honeyfarm via GRE project • Operational security exercises • Others?
