SP Security Empowerment Materials
The following materials will help SPs, Hosting Centers, and Operators of any large network get details on a wide range of SP Security techniques. Many of these techniques are taking advantage of technologies that already exist in the network – it just takes a bit of time to empower yourself and deploy them. Most of these techniques are different from traditional enterprise approaches to security – using the tools of forwarding, QOS, and other technologies used to glue the Internet together to protect the Internet. Many of the links are to materials with a Video on Demand (i.e. the NANOG Sessions and Cisco Powersessions). These help you hear from people who are doing the technique and/or created the technique – many from large networks themselves.
STEP 1: Join Communities of People Working Together to Mitigate Miscreant Activities
Security on an SP’s Network is not something you can do alone. Effective security mitigation and prevention dictates the need to collaborate and work with peers all over the planet. Prior to September 2002, there were not any SP Security communities who worked with each other to mitigate threats. Today there are several groups – each evolving specialties.
It is strongly encouraged for all SPs to join and activity participate in these mitigation communities. In fact, not doing so is viewed as putting their SP business at severe risk to revenue disrupting events.
NSP-SEC is one of the best inter-provide mitigation forums active today. It is a community that is more than a mailing list, with secure line of communication and regular meetings. Details for NSP-SEC are listed here:
“Cyber defenders, ever vigilant, ever responsive.” -Marjorie Gilbert, 2003
The nsp-security [NSP-SEC] forum is a volunteer incident response mailing list, which coordinates the interaction between ISPs and NSPs in near real-time and tracks exploits and compromised systems as well as mitigates the effects of those exploits on ISP networks. The list has helped mitigate attacks and will continue to do so.
Who Qualifies for NSP-SEC Membership?
Step one is to insure you meet the qualifications for NSP-SEC. Some common questions to ask yourself are:
- Do you work for some type of IP transit provider, huge multi-homed content provider, or service provider?
- Does your job include Operational Security?
- Are you willing to offer free services, data, forensic, and other monitoring data to the NSP community?
- Do you have authorization to actively mitigate incidents in your network? Do you actually log into a router and do something to mitigate an attack or call someone to task them to do the work?
- Do you have the time for a real-time NSP mitigation forum?
If yes, then you might fit the expectations to be on the NSP-SEC Mitigation or Discussion Forums.
How to Join NSP-SEC?
Joining NSP-SEC is not simple – requiring layers of trust to be built with members of the community. Trust is built by working with members of the community. The challenge is finding out who is part of NSP-SEC so you can stat building a trust relationship. The following are guidelines that are known to build trust relationships to get on NSP-SEC. It is a path which will benefit the SP Security operator (or just a normal SP Engineer).
- SP Security Contacts for all your Upstream SPs. Many of the large SP’s in the world are already part of the NSP-SEC community. So insuring you have the SP Security contact information for all your upstreams is a way to built trust relationships. Besides, you need to have this information in case there is a critical security incident.
- DSHIELD Membership. DSHIELD (see below) is a community which actively analysis and mitigates issues on the Internet. It is another sphere of trust with members who intersect with the NSP-SEC world.
- NSP-SEC BOFs. Meeting people in person is perhaps the best way to get to know other NSP-SEC members. For that reason, NSP-SEC has BOF sessions at NANOG (www.nanog.org), RIPE (www.ripe.net), and APRICOT (www.apricot.net).
- Drone Armies. Drone Armies offers a different and broader community mix as compared to NSP-SEC. There may be more people who know you on Drone-Armies than on NSP-SEC. Yet, there are a lot of NSP-SEC members on Drone-Armies (and visa-versa).
- National CERTs. Meet your national CERT. Know the members, actively participate, and promote their activities. Many National CERTS are on NSP-SEC.
DShield provides a platform for users of firewalls to share intrusion information. DShield is a free and open service. If you use a firewall, please submit your logs to the DShield database. You may either download one of our ready to go client programs, write your own, or use our Web Interface to manually submit your firewall logs. Registration is encouraged, but is not required. Everybody is welcome to use the information in the DShield reports and database summaries to protect their network from intrusion attempts.
Distributed Detection Systems Individuals and Organizations can participate:
Dshield – www.dshield.org
he primary issue in internet security is not that hackers troll the Internet, but rather that the Internet is chock full of insecure systems which are easily compromised, providing means for hackers to perform untraceable, indirect attacks. The only profound way to improve Internet security is to reduce the number compromised systems and minimize the amount of time that a system remains in a compromised state. (Click here to learn more about the myNetWatchman Vision.) myNetWatchman achieves its goals through:
- Security Event Aggregator
- Centralized, web-based firewall log analyzer
- Fully automated abuse escalation/management system
Drone-Armies’s mission brings together NSPs, Big Enterprises, Security Solutions vendors, Operating System Vendors, Networking Vendors, and Researchers together is an aggressive mitigation forum. It is a parallel forum to NSP-SEC. While NSP-SEC’s membership community focuses on the SP operational security community, Drone Armies focuses on the strength of the synergy of diversity to mitigate threats – combining host protection interest – system protection interest – and network protection interest. The nature of the community tends to focus on BOTNET and Trojan/Worm/Virus disruption.

MWP – Malware Providers
MWP is a mitigation community specializes in detecting and reporting detected malware hosting(s). These include droppers trojans, phish, and other miscreant systems. The community is inclusive of a broad segment of the white hat community. Phishing detection/disruption is one of the general consequence of MWP’s detecting and reporting.

NANOG SP Security Seminars and Talks
The NANOG Coordination Committee actively works to product sessions and seminars to help foster security on the Internet. All sessions are taped and converted to VOD for all to use for their personal education. Over time, this effort has generated a valuable On-Line Tutorial for engineers and organzations seeking to learn more about running a more secure network.
