Botnets: Most Prevalent Threat on the Internet for the Enterprises

Based on the total number of transactions, Zscaler reports botnets as the biggest security risk on the Internet for the enterprises. "Once a host gets infected, the botnet usually spreads quickly within an enterprise.

Abuse Reporting: Names vs Numbers

For email usage, abuse reporting requires cooperation between senders and receivers. That's why RFC 5965 specified a standard format for it. However, Wikipedia lists only 18 feedback providers today. It is often said that the number of legitimate mailbox providers in the world is rather small, possibly some hundreds of thousands, but certainly more than that. more

Filtering Spam at the Transport Level

An interesting new paper from the Naval Postgraduate School describes what appears to be an interesting new twist on spam filtering, looking at the characteristics of the TCP session through which the mail is delivered. They observe that bots typically live on cable or DSL connections with slow congested upstreams. ... This paper tries to see whether it would be practical to use that info to manage spam in real time. more

How AT&T and Verizon Further Consolidated the Wireless Marketplace While Most Weren’t Looking

Before anyone claims victory for the consumer in AT&T's abandonment of its "swinging for the fence" gambit to buy T-Mobile's market share and spectrum, consider what did not make many headlines this week. Both AT&T and Verizon substantially shored up their spectrum stocks with major deals with Qualcomm and several cable companies respectively. Solid hits for both carriers: not homeruns, but very strategic singles and doubles. more

DDI Integration: We Need IPAM

I am a big fan of DDI (DNS, DHCP and IPAM) as magical trio to manage all transactions on network infrastructures... Or to say the least: make it possible. Basically it makes these "Core Network Services" concise, manageable and integrated. It basically makes the network infrastructures of today and the future possible. There is however one thing that continuously seems to irritate when talking about integrating these services on networks. more

The gTLD Opera

The curtain rises on January 12th 2012 but key players are still singing different tunes. Let's peek into their performance as they start taking center stage. FTC, the Federal Trade Commission, has sent a letter to ICANN on December 16th 2011. Re: Consumer Protection Concerns Regarding New gTLDs. They write; "We write now to highlight again the potential for significant consumer harm resulting from the unprecedented increase in new gTLDs." The following paragraph clearly highlights the lack of information about the ICANN gTLD platform. more

DDoS Mitigation: A Blend of Art and Science

As DDoS attacks become larger, more frequent and complex, being able to stop them is a must. While doing this is part science, a matter of deploying technology, there is also an art to repelling sophisticated attacks. Arbor Networks, Citrix and others make great gear, but there's no magic box that will solve all your problems for you. Human expertise will always be a crucial ingredient. more

IP Address Space Covered by Certificates

Since the RIPE NCC launched its Resource Certification service, there is a steady increase in the number of prefixes covered by certificates. The Resource Certification (RPKI) service was launched at the beginning of 2011. The system enables network operators to perform Border Gateway Protocol (BGP) origin validation, which means that they can securely verify if a BGP route announcement has been authorised by the legitimate holder of the address block. more

The Myth of the Unintended Infringer in SOPA and PIPA

In a recent op-ed piece in TheHill.COM, some friends and I described the futility of mandated DNS blocking as contemplated by the SOPA (H.R. 3261) and PIPA (S. 968) bills now working their way through the U.S. Congress: No Internet user is required to use the Domain Name servers provided by their ISP. And if millions of American citizens who for whatever reason want to engage in online piracy can no longer do so because Congress has passed this law and their ISP is now filtering the citizen's DNS lookups... more

TLDs, CJD and Other Mad Cows

"At every crossroad on the road that leads to the future, tradition has placed against us ten thousand men to guard the past". These were the words of Stanley Prusiner in 1992 describing the opposition to his radical discovery of what he called prions, the causative agents of a clutch of baffling brain diseases. These include kuru, affecting New Guinea cannibals, Creutzfeldt-Jacob disease (CJD), and BSE or mad cow disease. And today these guardians of the past are in place again at the crossroad that leads to a future of thousands of top-level Internet domain names. more
