DPI

DPI, Employees, and Proper Inspection

/ Christopher Parsons

In my last post I alluded to the fact that Deep Packet Inspection (DPI) technologies could be used by businesses to try and reduce the possibility of ‘inappropriate’ employee use of bandwidth and wrongful or accidental transmissions of confidential IP. In that last post I was talking about IT security, and this post will continue to reflect on DPI technologies’ applications and benefits to and for corporate environments.

A Quick Refresher on DPI

From ArsTechnica:

The “deep” in deep packet inspection refers to the fact that these boxes don’t simply look at the header information as packets pass through them. Rather, they move beyond the IP and TCP header information to look at the payload of the packet. The goal is to identify the applications being used on the network, but some of these devices can go much further; those from a company like Narus, for instance, can look inside all traffic from a specific IP address, pick out the HTTP traffic, then drill even further down to capture only traffic headed to and from Gmail, and can even reassemble e-mails as they are typed out by the user.

For a slightly longer discussion/description of DPI I suggest that you look at the wiki page that I’m gradually putting together on the topic of Deep Packet Inspection.

Boost Up Your Net With ISP Injections

/ Christopher Parsons

I’ve written about Deep Packet Inspection (DPI) technologies before, and their various potential privacy issues. Generally, I’ve talked about how the possibility of having your ISP persistently monitor your online actions could stifle the substantive abilities exercising of autonomy, liberty, and freedom of conscious. I won’t revisit those issues here, though I’d recommend checking out my earlier post on DPI. What follows examines how ISPs are injecting information into the webpages that you visit, which prevents you from viewing webpages as they were designed.

Web Tripwires

When you visit a webpage, your computer downloads a little bit of code and renders it on your screen – the web is an environment where visual stimulation necessitates copying data. Recently, researchers from the University of Washington and the International Computer Science Institute have discovered that about 1.3% of the time what is displayed on your computer’s screen has been altered. This having been said,

Three-Strike Copyright

/ Christopher Parsons

To fully function as a student in today’s Western democracies means having access access to the Internet. In some cases this means students use Content Management Systems (CMSs) such as Drupal, Blackboard, or wikis (to name a few examples) to submit homework and participate in collaborate group assignments. CMSs are great because teachers can monitor the effectiveness of student’s group contributions and retain timestamps of when the student has turned in their work. Thus, when Sally doesn’t turn in her homework for a few weeks, and ‘clearly’ isn’t working with her group in the school-sanctioned CMS, the teacher can call home and talk with Sally’s parents about Sally’s poor performance.

At least, that’s the theory.

Three-Strike Copyright and Some Numbers

I’m not going to spend time talking about the digital divide (save to note that it’s real, and it penalises students in underprivileged environments by preventing them from acting as an equal in the digitized classroom), nor am I going to talk about the inherent privacy and security issues that arise as soon as teacher use digital management systems. No, I want to turn our attention across the Atlantic to Britain, where the British parliament will soon be considering legislation that would implement a three-strike copyright enforcement policy. France is in the process of implementing a similar law (with the expectation that it will be in place by summer 2008), which will turn ISPs into data police. Under these policies if a user (read: household) is caught infringing on copyright three times (they get two warnings) they can lose access to the ‘net following the third infringement.

Shaping your Identity

/ Christopher Parsons

It’s been a while since I’ve been updating this blog regularly – since I last wrote, I’ve completed my Master’s thesis, traveled to Brasil, sent out applications to Doctoral programs, found (temporary) full-time employment, and rested my brain a bit. Now, I feel rejuvenated, and ready to get back into the swing of things.

Setting the Stage

We are increasingly living in a hybrid world, one where our lives are being digitized. We eat food (analogue) but order it online (digital); we use our voices to talk with one another (analogue) using cell phones (digital); we read cooking recipes (analogue) from recipe websites (digital). In addition to what we actually do, what happens around us, and shapes how we are capable of interacting, often occurs within digital spaces – banking institutions are networked, government documents are send across departments by email, and major corporate executives that make (oftentimes) global decisions seem to have Blackberries surgically attached to themselves.

Public and Private Digital Space

/ Christopher Parsons

Ask yourself a question: Why does having private space matter to you? When it comes right down to it, why is it important to maintain the public-private distinction?

Some might immediately assert that the distinction establishes a space where government interests cannot easily intrude, and that the private domain is where individuals develop themselves while hidden from the nation-state’s coercive gaze. When we can speak privately and associate off-the-record we can more easily develop friendships that we might have otherwise shied away from. Moreover, without this private space individuals might not be comfortable talking to one another about radical political, ethical, or cultural issues – if the state could be recording our discussions, then we would have to evaluate whether or not we really wanted to discuss topics such as the value of overthrowing the present government, the importance of weakening the authorities’ scopes of legitimate action, or the value of weakening national rhetoric in favour of plurality.

While there have been clashes about where the division between public and private should be, those clashes often relate to where a line should be drawn rather than about abolishing the line entirely. Some, of course, insist that the public and private are mere phantasms, and that they only exist because we perpetuate a myths of their existence, but for this position to gain traction it must grapple with the necessary co-originality of public and private that is revealed in an examination of the nation-state’s founding. Feminists (accurately) focus on the harms that the strict division between public and private have caused, such as the suppression of women’s issues and the criminal discrimination against women and their labours, but this demonstrates that there is a porous boundary between public and private that must be examined rather than asserting that it absolutely does not exist.
