Skype (Mac) – how not to be a supernode

I have re-visited Skype on OSX and get a strong indication that we will not be seeing Skype v.3 on OS X in the near future.

After chasing multiple sources (mainly based on reverse engineering the Skpe clients) I have reached a conclusion that the supernode function is not enabled in either the OS X or the Linux clients, and that this is further protected by using port 35502 for incoming connections and not using port 80 and 443 as alternatives for incoming connections in case it was introduced in a later patch.

=== begin control details ===

Installation Details:
These computer are running OSX.3 and OSX.4 (not OSX.5 at this stage)

Bandwidth management measures:

  1. Skype will only be started for pre-arranged calls and to shut it down when it is not being used.

    Stop autostart: via Mac’s System Preferences, select Accounts. Select the user account, then choose Login Items. Locate Skype in the list, highlight Skype then click on the ‘minus’ symbol beneath the list. Don’t simply untick it; REMOVE it.
  2. “supernode disabled” — as we are on OSX the registry fix is unavailable; 3rd party evidence suggests that the supernode function is only enabled in the Windows client.
  3. Skype usage will be monitored using our K2 licencing keyserver application.
  4. Network traffic from this computer will also be monitored.
  5. Use port 35502 for incoming connections;

    DO NOT use port 80 and 443 as alternatives for incoming connections.

Internet Explorer 8, Beta 2

At the end of August 2008 Internet Explorer 8 Beta 2 was released. While IE8 Beta 1 was focused on the development community, Beta 2 is aimed at consumers.

Internet Explorer 8 is the latest version of the familiar web browser you are most comfortable using, helping you get everything you want from the web faster, easier, more privately and securely than ever before.
* Faster Internet Explorer 8 is more responsive with new pages and tabs, opening up fast and reliably. You can now get to the information you care about most, in fewer steps; one click access to your webmail, favorite news sites or other online services.
* Easier Reduce the steps to accomplish many common tasks, and automate your access to real time information updates. You can keep track of your favorite sports team, news, weather with a single click.
* More Private Helps protect your privacy and confidential information where ever you go on the web.
* More Secure Helps protect and stop malicious software from reaching your PC, and makes it easier to detect when a website is an imposter.

Lots of evaluation to be done here …

Now there’s a shocker! After evaluating Internet Explorer 8, the folks over at the exo.performance.network (the ones who brought you Windows Sentinel) are declaring it to be one seriously bloated piece of software. Not only is it “fatter” than IE 7, it’s also more resource-intensive. – InfoWorld [5]

Given that that this is a Beta there will be lots of debug code running in the release so we can expect to see some bloat than IE7. But how much is too much?

Google Chrome – Google joins the browser market

All of us at Google spend much of our time working inside a browser. We search, chat, email and collaborate in a browser. And in our spare time, we shop, bank, read news and keep in touch with friends — all using a browser. Because we spend so much time online, we began seriously thinking about what kind of browser could exist if we started from scratch and built on the best elements out there. We realized that the web had evolved from mainly simple text pages to rich, interactive applications and that we needed to completely rethink the browser. What we really needed was not just a browser, but also a modern platform for web pages and applications, and that’s what we set out to build. [1]

We will be launching the beta version of Google Chrome tomorrow in more than 100 countries. [1]

Google Chrome beta will only be available for Windows, but Google say that Mac and Linux versions are coming soon.

One slight problem – Google Chrome vulnerable to carpet-bombing flaw.

Deciphering Social Networks (ID: ERS0806)
Mike Gotta (Burton Group)

Abstract:
Adoption and usage data regarding social networking trends by consumers has convinced many business and IT leadership teams that social network sites, and their technological underpinnings, can be viewed as viable usage models to satisfy the communication, information sharing, and collaboration needs of the enterprise. In addition, strategists believe that the technology that supports such sites should be considered a credible technological model to help guide internal deployments. Higher education institutions should be careful, however, that they don’t blindly adopt solutions simply because they are popular at the moment. Strategists unfamiliar with the field of social networks beyond its technological aspects should pay attention to issues such as:
* How culture influences awareness of, and engagement in, social networks
* How social networks can be structured in different ways with, or without, technology as a mediation method
* How relationship dynamics influence participation (e.g., politics)

In the August 2008 survey we received responses from 176,748,506 sites. This month’s overall growth of 1.3 million sites reflects Apache’s growth of 1.2 million and Google’s gain of half a million sites, but a loss of 760 thousand sites using Microsoft IIS.

Harsh comments in your blog? It could be a LOT worse;

Russian police kill anti-government website owner
The owner of an independent website critical of authorities was shot and killed by police today in a volatile province in southern Russia, his colleague said.
The killing of Ingushetiya.ru owner Magomed Yevloyev could incite tensions in the province of Ingushetia west of Chechnya, which has been the site of frequent attacks on police and other officials.

SWOT matrix
How can you outline a system’s security state succinctly, yet without omitting important points? Consider using the SWOT matrix to summarize your perspective. This approach is particularly effective when communicating with managers and executives, who are usually familiar with SWOT analysis.
The acronym SWOT, which stands for Strengths, Weaknesses, Opportunities and Threats, is designed to remind you of the key factors to consider when analyzing a situation. A SWOT matrix is a table that presents these elements in a compact manner. Take a look the SWOT matrix template below.
