We Bought A Firewall. Isn't That Good Enough?

I've been reading Jon Udell's print and blog pieces for as long as I can remember. I may not always have a personal interest (this is not the same as having a differing opinion) in some of his topics but when I am interested, I typically find myself in 90+% agreement. He's been blogging about the lack of availability to public - specifically at the local or community level - data in an normalized (or reasonably transformable/convertible) format through standard, programmatic "pulls and pushes" (RSS, SOA, etc.).

While the topic is generally interesting to me, three paragraphs of his post are particularly interesting and germane to the information security and data protection world I play in:

"As I meet with intelligent and well-educated professionals in my community, and talk with them about how to synchronize calendar information from a variety of sources, I realize that they simply have no intuition about the difference between a PDF file and an ICS file that contain the same calendar information. Both are computer files, right? Both can be posted to the web, right? Both can be searched, right? Problem solved.

. . .

These are ways of computational thinking unknown to most people. As a school administrator, librarian, city planner, social worker, or retail store owner, nobody expects you to understand and apply these principles.

And yet almost everybody needs to harmonize personal and organizational calendars. And many individuals and organizations need to flow their calendar data into other contexts to promote and coordinate their activities. "


If you substitute file formats for security controls and calendars for security-related procedures, I feel that the same three paragraphs capture the essence of the reason we still have phishing and spam problems, botnets, etc.: people not involved in "the trade" simply do not have the proper background nor the mindset to think properly about data protection.

Sure, some people and organizations may buy themselves a firewall and antivirus software and may ask, "We just bought a firewall. Isn't that good enough?" The answer, clearly, is "more than likely not." And this should never be presented or perceived as simply a push or a bait-and-switch attempt to push more security products or controls - the need for those elements comes from stated organizational objectives and/or policies and detailed risk analysis where the spend on security and protection controls is aligned with the value of assets being protected.

Who is qualified to make these assessments? How many people or groups are qualified (identification and selection, implementation, on-going maintenance, etc.) to handle major electrical, plumbing or construction work in their home or offices? Bad choices could easily lead to bad happenings, to put it rather simply. Viewed through a similar prism we can ask how many people or groups are qualified to properly assess risk to whatever they're trying to protect or hide or what have you? Same general answer: bad choices easily could lead to bad happenings.

Now, my comments emphasis a specialization or expertise necessary to make intelligent data security and protections decisions. We're all interested in protecting our data or at least assuming the firms we interact with do the same but largely, both cases are not true. On the individual side, a majority or people are willing to share their user IDs and passwords with strangers for a chocolate bar and at the company level, those firms who don't see a drop in stock price (consumer confidence and willingness to spend) often do very little.

This has been a bit of a long-winded way of getting back to Jon Udell's three interesting paragraphs. A few years ago, I led a team of network security staff at a private New England university. One thing I stressed was collaboration with peer groups, visibility to higher decision-makers and a decidedly NON-jackboot thug approach toward requests and assistance; we were to be in the business of analysis of needs (perceived and actual) and distilling them to appropriate security controls that could best support them. I doubt I was successful in this approach as my group largely functioned without mandate but I still to this day try to keep in mind a message I pushed to my staff and to the groups I met with:

I may not know much about medical imaging or financial aid records or your particular area of expertise in computer science, biology, music, etc. What I do know a bit about is data protection and security. We meet and there is a disconnect between us. What is important to you as a researcher or faculty member? What is important to me as a staff member charged with protecting you and your data?

DNA sequencing, firewalls, intellectual property...all of this reduces to knowing and working with your constituents, addressing their needs, listening to their concerns and presenting a common, organizationally based (re: consistent) to risk management and data protection that the groups you ultimately serve can do so in a consistent manner while (hopefully) taking a risk-based approach to assessment, mitigation and remediation.

Google Gears, Part 1

I didn't quite get Google Gears at first. Do I REALLY need to read my blog feeds offline? As it turns out, Google Docs is getting offline support now.

Do I care? Sort of.

When you consider some other Google properties - Blogger, YouTube, News, Book Search, Picasa - you can see how Gears starts to fit into the Google experience. Working on a blog posting? Do it on the train during your commute, it's stored in the Gears database and automatically posts to Blogger when you get an active net connection. Just capture something newsworthy, Mr. Citizen Photojournalist? Dump it from your camera to your laptop running YouTube offline and the video will be stored in the Gears database until it can sync your content with your YouTube account online. Picasa already has a thick client but there's no reason Picasa web albums could not be connected to Gears for offline work.

Interestingly, these ideas aren't what I care about. It's certainly interesting from a usability point of view and allows for greater permeance of Google in your life (if you think that's a good thing) as well as allowing one to publish their virtual lives out to the Googlesphere from anywhere, connected or not.

What I'm truly in is the security controls that are utilized to protect the Gears database and the general security architecture of Gears and all of the Google properties and tools that are becoming offline-enabled. More to follow after I do some research into this.

Reading List #7

A recipe for success:


Mix thoroughly in a steampunk bowl with a biblical spoon until "His Dark Materials" forms.

After my previous foray into and completion of Neal Stephenson's Baroque Cycle trilogy, I was thrilled that this trilogy - a virtual trifecta of literary quality - found its way to me.




Enjoy!

Another Use for Second Life


Historical Maps in Second Life

This is great. I've previously posted about some unexpected consequences SL but I think this one - a San Francisco map collector who set-up his own SL island to display his collection - is a great use of SL that (to me at least) was completely unexpected. From the MIT Technology Review:

"A new installation inside Second Life is bringing alive one of the world's largest collections of antique maps. Called the David Rumsey Maps Island (registration required), the Second Life site is San Francisco map collector David Rumsey's latest high-technology plan to share his collection with as large an audience as possible."

Google Sites

Google Sites looks to be a SharePoint alternative of sorts.

I'm still trying to figure out where Gears fits into it all.

Google Central (part 1)

Update: Grand Central has become Google Voice

-----

I feel that I'm turning into some sort of Google-watcher these days or have been a Google junkie without realizing it.

A couple of days ago I found an entertaining video on YouTube (how apropos) of interesting sites and places to visit in Google Earth. I recently posted about new Google search functionality and presentation options. Before that it was a brief look at Google's Android mobile phone platform. Last year I was - and will soon be again - looking at Google Trends as a potential prediction tool for the American Idol contest winner.

This is sort of interesting as it brings a set of old school (Groups - Usenet, Scholar - refereed journals, and Glossary - reference sources) content together with new school (YouTube, Blogger, Google News commentary) together in a jumble of seemingly disparate audiences through Google-branded channels. It clearly extends new school functionality (Web 2.0) into old school mediums (proto-web and Web 1.0) while trying to preserve or normalize the presentation, experience and general consumption of content and services. Through this normalization process, Google is able to preserve/build brand recognition (Google TM) Grand Central, "a production of Google." Their info page asks and answers: "What is GrandCentral? Get all the same calls, but in a whole new way." That's all fine and dandy; it's nothing you can't get from existing, consumer VoIP providers. Their feature set is pretty comprehensive which conceptually place it as a virtual voice communication firewall in some regards.

That's kind of cool but it doesn't seem like a Googlesque sort of venture. Until you add other Google services. Now you have an interesting stack supplying different, but converging on, fully integrated services:

This is only a partial analysis (and none too in-depth, by any means) and doesn't take into account relevant issues, such as Google's wireless 700 MHz spectrum bid, which help with the convergence understanding and visualization. I'll post again as it's sort of fun to be an armchair Google strategist.

Google Earth Fun

Ten minutes of mostly entertaining Google Earth fun.


Secrets Of Google Earth

The PC World staff have some still shots of some of the highlights as well as a Google Earth placemark file you can download and import to explore on your own.

My Coffee Maker...Seg Faulted???



So it's snowing today and I'm working from home for other reasons. Isn't it nice to enjoy a cup of hot, freshly brewed coffee in the morning. It sure is...until your coffee maker decides to dump core.

Crazy.

I haven't tried it again but if I need a new unit it damned well better be able to receive SNMP traps so I can set it to brew while I'm away.

Useful Kibble

I've been catching-up on some reading and thought I would simply share three sites/feeds that I find to be truly useful. In no particular order:

  • Lifehacker, "an award-winning, daily blog that features tips, shortcuts, and downloads that help you get things done smarter and more efficiently."
  • Wise Bread "is a community of bloggers here to help you live large on a small budget."
  • Parent Hacks "is a collaborative website that collects and publishes parents’ tips, recommendations, workarounds, and bits of wisdom – their hacks – in a single pot so we can all partake."
  • Geekdad, "tech toys, science projects and other nerdy things to do with your kids."

They may not have ground-breaking news, cutting edge technology reviews or deep, theoretical insights but I always manage to extract some useful kibble from them to apply to my daily existence.

Great Analysis of the World's Under-Sea Fiber Network


"A flotilla of ships may have been dispatched to reinstate the broken submarine cable that has left the Middle East and India struggling to communicate with the rest of the world, but it took just one vessel to inflict the damage that brought down the internet for millions."

New Google Search Features

Google has introduced some new search features as experimental through Google Labs. They've added
  • right- and left-handed search navigation
  • keyboard shortcuts for search results
  • keyword suggestions
  • alternate views for search results



  • I like the left-handed search navigation and was playing with the layout and widgets a bit myself last summer when playing with Google's Web Toolkit. eBay has been doing some very similar UI work in its eBay Playground site that I've enjoyed. Amazon tends to overwhelm me at times with JSON this and AJAX that and they can't seem to resist the urge to package the search results and product descriptions to the extreme. I guess this shouldn't surprise me so much as they are a self-billed department store. Netflix, on the other hand, strikes the right balance with me through their consistent and concise detail drill-down through the AJAX essentials, XMLHttpRequest object and javascript onmouseover() event.

    I don't particularly care about keyboard shortcuts and search results. This is a personal inconsistency however as I don't use keyboard shortcuts in Gmail either but almost always use the keyboard to navigate between applications, tabs and the OS in general. Maybe this is my unverbalized position that I just don't like the way Google implemented keyboard shortcuts. Maybe I'm just inconsistent after all.

    The keyword suggestions have been available as a Google Labs offering called Google Suggest for a while and the search bar in Firefox provides JSON-enabled search term suggestions.

    The alternative search results are a great move forward with regard to search result presentation, specifically addressing the need for better contextual-based and grouped/ordered search results. I've written about this previously and was eager for new search primitives to address this perceived shortcoming or at minimum search options that accomplished the same thing.

    At least I'm not alone in liking the latest search presentation options. Ars Technica described it simply as "awesome".

A Game-theoretic Framework for Creating Optimal SLA/Contract

Intriguing paper. Game theory is certainly a key tools of negotiations, conflict resolution, optimal cooperation problems, etc. Very interesting to see it applied in a practical manner to IT-related contracts.

Abstract: An SLA/Contract is an agreement between a client and a service provider. It specifies desired levels of service and penalties in case of default. It is of interest from the Service Providers point of view, to determine the optimal contract, that will maximize its utility. In this work we model the situation based on the notion of Moral Hazard: providing a good service is costly and results are affected by the resources involved. As a consequence, a credible contract must fulfill the incentive compatibility constraint. We extend the above model to take into account the possibility that there might different types of clients, and that the Service Provider will offer a menu of contracts intended for each of these clients, as a means of maximizing utility. From the Service Providers point of view, finding an optimal contract will consist of solving a nonlinear optimization problem subject to constraints. We derive conditions under which these constraints will take a simple form and we analyze a scenario, in which, the randomness comes from the Response Time of a given IT Service, and the input is the number of servers that will be dedicated to each client.
