In a speech today at the Intel Developer Forum, Intel Senior Vice President and Chief Technology Officer Pat Gelsinger said that by adding an overlay network of computational services to the Internet - made up of computing and storage resources -- the industry could bring greater intelligence into and across the network core. This would transform the Internet from a data transmission pipe into a vast platform for hosting a wide array of services available to the world's six billion inhabitants. Gelsinger referred to this approach as the ability to provide planetary-scale services.

* The Looking Glass service runs on our remote route collectors. * MyASn is a notification system for BGP route propagation. * RISwhois shows prefixes, which include the specified IPv4 or IPv6 address, and their AS(es) of origin according to BGP tables of RIS Route Collectors. ( Web Interface) * Uni Roma 3's BGPlay, a path visualisation tool hosted by RIPE NCC. * ASInuse determines when an AS-number last appeared in the global routing table collected by the RIS. * PrefixInuse determines when a prefix last appeared in the global routing table collected by the RIS. * Search by AS searches the RIS database according to selected AS number. * Search by Prefix searches the RIS database by given prefix. * RIS BGP Routing Hot Spot Utility by AS generates lists of prefixes, originating from a specified AS, for which high BGP announcement activity has been observed by our Route Collectors. * RIS BGP Routing Hot Spot Utility generates lists of prefixes for which high BGP announcement or withdrawal activity has been observed by our Route Collectors. * RIS DB Status displays when data was inserted into the database. * De-Bogonising New Add ress Blocks Report based on the announcement of /16 and /21 pilot prefixes from 85/8, which was recently allocated by IANA to RIPE NCC. * Debogon Prefix Reachability Tool, an icmp-based connectivity tool where one can set the source address within the range of a debogon pilot prefix. * RIS BGP Beacon Overview, matrix that simplifies querying the RIS for beacon data.

What has happened is this: With the introduction of IPv6 based name servers, some resolvers running on hosts that have IPv6 enabled (which includes the default settings on many recent releases of Linux) but which don't have actual IPv6 connectivity, seem to be trying to talk to those IPv6 based servers. It takes time for these never-to-be-answered queries to time out and for the resolver to move on to a usable IPv4 address. Users perceive delays (four seconds) for names to resolve. More about this can be found in a posting on the NANOG mailing list and on comp.protocols.dns.bind

One of the ways in which TLS breaks when run over an unreliable data network is that there are dependencies between the data records. In particular, decrypting record X+1 depends upon knowing information about record X. When you're one of the communicating peers, this isn't generally a problem because TCP guarantees the reliability of the transport, but in passive sniffing applications, it's reasonably common to lose packets. With some thought, however, it turns out that with some thought you can actually reconstruct most of the remaining data stream.

Intrusion Detection Systems GOLD MEDAL: Enterasys' Dragon Intrusion Defense System Enterasys' Dragon epitomizes the transition of IDSes from "reactive detection" to "proactive correlation." Rather than firing off thousands of alerts based on single-node scanning, Dragon uses multiple virtual sensors to correlate event data from across the network and compare it to collected data on the network's vulnerability posture. The process, managed through Enterasys' Dynamic Intrusion Response (DIR) system, results in more accurate and timely intrusion management, as well as fewer false positives. Enterasys has transformed Dragon from a standalone IDS to the cornerstone of its network security architecture strategy. SILVER MEDAL: Cisco IDS USER COMMENTS: "Cisco does a good job of understanding where our threats are coming from and changing its products to address them." "Technology-wise, it leads most of the network vendors." BRONZE MEDAL: ISS's RealSecure Network USER COMMENTS: "ISS has a proven IDS infrastructure." "It's the leader in the IDS market. Intrusion Prevention Systems GOLD MEDAL: TippingPoint's UnityOne TippingPoint, just acquired by 3Com, set its sights on the security market in 2001 with the launch of UnityOne, one of the first inline traffic monitoring and automated response devices. It's an IDS on steroids, with blazingly fast inspection and throughput speeds. TippingPoint is improving upon its foundation through the release of a number of appliances to fit the needs of various-sized enterprises. Its R&D team continues to innovate by producing an increasingly broad attack signature database, an optimized detection engine and more reliable automated response measures. While many enterprises shy away from depending on the auto-response capabilities of their IPSes, UnityOne shops use the appliance with a high degree of confidence. "It's the first IPS system that we can stick in front of any workload," said one director of information security.

It has taken several months for PIR, the registry operator for .org, to publish its month report for the period. The June report from PIR claims that no name resolution outages that month. PIR's July report indicates 60 minutes of "unplanned" outage. Was that July outage of 60 minutes the same failure as the one that occurred on July 1? We can not tell because the PIR July report says absolutely nothing about the date of the outage, its cause, or what corrective measures were taken to ensure that it does not recur.

A group of prominent Internet providers are teaming up with a security vendor Arbor Networks to form the Fingerprint Sharing Alliance. Through the use of Arbor Networks Peakflow SP internet appliance (which is an OpenBSD box with some secret sauce mixed in), members of the alliance can share internet threat information with each other in real time.

Microsoft Research's approach gets around this by re-encoding all the pieces, so that each one that is shared is actually a linear combination of all the pieces, fed into a particular function. The blocks are then distributed with a tag that describes the parameters it contains.
