Cities, not cornfields, draw data centers

Google built a data center in an Oregon town with a population of about 15,000. Yahoo established chicken-coop style data center in New York state farm country. And Apple runs an iCloud data center in rural North Carolina.But building big data centers in rural areas may be more the exception than the rule. Most data centers are located in, or at least close to, major Metro areas, acording to a new study. flickr/Tony Webster Google Data Center - The Dalles, OregonTo read this article in full or to leave a comment, please click here

Why Would You Need BGP-LS and PCEP?

My good friend Tiziano Tofoni (the organizer of wonderful autumn seminars in Rome) sent me these questions after attending the BGP-LS and PCEP Deep Dive webinar, starting with:

Are there real use cases for BGP-LS and PCEP? Are they really useful? Personally I do not think they will ever be used by ISP in their (large) networks.

There are some ISPs that actually care about the network utilization on their expensive long-distance links.

“Split and smear” your security policies: Static Unidimensional vs. Dynamic Multi-Dimensional Policies

In my previous post I explained why current security architectures aiming at inspecting all inline traffic via hardware appliances are failing to provide proper segmentation and scale in modern day data centers.  As I described, this has nothing to do with the type of security technology being deployed but rather with engineering security services that can answer the requirements of scale, high bandwidth, micro-segmentation and distributed applications.

We have to remind ourselves why we are having these architectural discussions: the application and service landscape has been virtualized, generally in excess of 70%, while entertaining any cloud solution will force you down the path of moving to 100% virtualization.  Yes, there are still physical servers and legacy applications to which we will extend security services to.  But instead of being the norm, we now have to consider their place in the overall architecture as exceptions and design security and networking services around what makes up the bulk of the workloads, i.e. virtualized applications in the form of VMs and containers.

With this understanding, let’s discuss how years of deploying hardware security architectures have boxed us in a complex unidimensional, sequential approach to security policies and how we can now move beyond this implementation scheme with virtualization and the proper software tools.

Pim Sparse Mode

Pim sparse mode – Multicast is used to send the data to the multiple receivers at the same time. Multicast reduces the load on the servers (Senders/Source in multicast term), provides efficient capacity usage on the network links.

Apple wants government to form commission over FBI demand

Apple CEO Tim Cook has asked the U.S. government to withdraw its court action demanding tools that will allow the FBI to hack the passcode of an iPhone, and instead set up a commission of tech, intelligence and civil liberties experts to discuss "the implications for law enforcement, national security, privacy and personal freedoms.""We have done everything that’s both within our power and within the law to help in this case. As we’ve said, we have no sympathy for terrorists," Cook said in an email Monday to Apple employees. Apple said it would gladly participate in the commission.The FBI has sought help from Apple for a workaround to the auto-erase function in an iPhone 5c, running iOS 9, which was used by Syed Rizwan Farook, one of the terrorists involved in the San Bernardino, California, attack on Dec. 2. The FBI is concerned that without this workaround from Apple it could accidentally erase data, while trying to break the passcode by "brute force" techniques.To read this article in full or to leave a comment, please click here

The disingenuous question (FBIvApple)

I need more than 140 characters to respond to this tweet:

It's an invalid question to ask. Firstly, it's asking for the emotional answer, not the logical answer. Secondly, it's only about half the debate, when the FBI is on your side, and not against you.


The emotional question is like ISIS kidnappings. Logically, we know that the ransom money will fund ISIS's murderous campaign, killing others. Logically, we know that paying this ransom just encourages more kidnappings of other people -- that if we stuck to a policy of never paying ransoms, then ISIS would stop kidnapping people.

If it were my loved ones at stake, of course I'd do anything to get them back alive and healthy, including pay a ransom. But at the same time, logically, I'd vote for laws to stop people paying ransoms. In other words, I'd vote for laws that I would then happily break should the situation ever apply to me.

Thus, the following question has no meaning in a policy debate over paying Continue reading

Comey says the FBI doesn’t want to break anyone’s encryption

FBI Director James Comey claims the agency doesn't want to break anyone’s encryption or set loose a master key to devices like the iPhone.The comment Sunday by Comey on Lawfare Blog comes as both Apple and the government last week appeared to have pulled out all the stops to defend their stands on an FBI demand in a court that Apple provide the technology to help the agency crack the passcode of a locked iPhone 5c used by Syed Rizwan Farook, one of the terrorists involved in the attack in San Bernardino, California, on Dec. 2.The FBI is concerned that without the workaround from Apple, it could accidentally erase data, while trying to break the passcode, because of the possible activation on the phone after 10 failed tries of an auto-erase feature. “We simply want the chance, with a search warrant, to try to guess the terrorist's passcode without the phone essentially self-destructing and without it taking a decade to guess correctly,” Comey wrote.To read this article in full or to leave a comment, please click here
