a. Nexpose from Rapid7:
This is a Vulnerability scanner, which does a good job at what it does, even in the Community Edition. Actually it lets you scan up to 32 machines without restricting the plug-ins.
If you look at the requirements in their site you’ll find the following:

• Microsoft Windows Server 2003 SP2 / Server 2003 R2*
• Microsoft Windows Server 2008 R2
• Microsoft Windows 7
• VMware ESX 3.5 and 4.0
• VMware ESXi 3.5 and 4.0
• Red Hat Enterprise Linux Server 5.x
• Ubuntu 8.04 LTS
• Ubuntu 10.04 LTS

I don’t expect support for Ubuntu 12.04 which was released a couple of weeks ago but I would think that RHEL 6 would be supported, especially since its release date was more than 13 months ago (2010-11-10).  It is very probable that a company building a new infrastructure (like in my case) would use the latest enterprise release and not one that is 5 years old, even if it will be supported for 5-8 years more.

To make matters worse, if you try to install on RHEL clones or derivates like  CentOS and Scientific Linux the installer says that they are not supported.

Workaroud: change the contents of the /etc/redhat-release during the installation process to the one used by RHEL.

b. Zenoss from Zenoss, Inc

This is an Open Core monitoring system, which one could compare with Nagios + Cacti or commercial tools like HP OpenView.
I couldn’t find a requirements sheet on the commercial website but on the community edition there is support for a wide range of OSes  and Linux distributions, again not including RHEL 6.

On the plus side it does offer support for CentOS (I would assume other RHEL clones) and its open core, so you can download the sources and build it yourself if you want to.

I’m wondering what other reason, besides cutting costs, would these vendors have for not supporting RHEL6.
Could it be the penetration rate or the market?  I’m going to see if I can find more information regarding this and publish an update afterwards.  Maybe I’ll even get a straight answer from the vendors themselves.

I had the pleasure of attending WebOS Developer Workshop in Mainz on Saturday Thgtwi (@thgtwi) did a great job with the organization. SuVuK(@SuVuK_open) did a nice report on the contents of the Workshop in his blog.

I took the opportunity talk about Security in the WebOS platform. I ran some tests based on WebOS 3.X, which is currently available for the HP TouchPad and is being opensourced as Open WebOS. The scope covers issues that can and should be applied to any mobile platform:

1. Architecture
2. OS / Platform
3. Authentication
4. Networking
5. Browser
6. Email
7. PIM
8. MDM
9. Other

I haven’t been able to complete the tests that I wanted to, some of them require Exchange to make use of the EAS policies, which I find interesting to see if the hold up to claims in the WebOS security white paper. I’ll post an update a soon as they are done.

This post was originally going to be dedicated to Karate, but I stumbled upon a reflective article: “Mind Control” by Pete Herzog and decided to try to build on top of it.

Pete, makes reference that given the speed of our sensors and our brain we basically live in the past: 80 ms in the past to be precise. So since we live in the past, our mind has been made up before we actually know or realize it; this enables us to perform complex tasks in “mental autodrive” or mental cruise control and how much energy is necessary to change mental patterns,

Karate is a good example of how through repetition, we create complex rules and responses of body and mind through repetition and concentration. It is possible to calculate the distance to something, even in movement, to hit it with the intended force: so when practicing you control strength, but in a sticky situation you can actual hit with all your might to defend yourself.

I had the pleasure of attending a karate-do class by Akita Sensei on Friday. And he focused on perfectioning small details in techniques, for example a Mae-geri or front kick. The idea was to concentrate on a couple of details, like:
a) The standing leg: ensuring it was correctly flexed, not overturned, but rather looking perfectly forward
b) The hip: should stay in a straight line, instead of automatically going forward to cover more space
c) The knee: should go up to the right place, at the right time
d) After the kick: retract the knee to the original position

If we can willingly create and change these patterns or rule-sets, why to we still react in primitive ways to known prompts? How many rules have been created for us by society and the modern way of life? How may rules do we have in place without even knowing it?

Considering the effort needed to change these rules, even if we use some cool mind tricks likes those described here; do we really want to do it? Can we make changes that will kick in in auto-drive or under stress? How do we discover if there are other rules with a higher priority than those we are trying to build in?

Sadly I don’t have those answers for you, but I think that the 15-20 black belts that were in that class with me will also be trying implicitly to find the answers to those questions

They are probably not my best coding, but they get the job done.

If they are helpful or useful for you let me know. If you have any suggestions or patches add a comment or contact me.

The Venezuelan telecommunications regulator Conatel, decided that operators have to implement mechanisms to block a mobile phone once reported stolen by its owner. This blacklist, so to speak, should work between the three main operators in the country and they even got RIM (the maker of the Blackberry devices) to agree on blocking these devices world wide.

Here is a link to the story in Spanish.

I remember from when I wrote my thesis back in 2003, that this feature is part of the original design of the GSM system, so these black lists could also be implemented at a worldwide scale. I also have information from a colleague from Romania that this system has been effectively implemented there and has reduced the theft rates dramatically.

So coming back to controlling risks; this measure if implemented correctly should reduce the risk of having a mobile phone stolen because it cannot be sold. The real impact should be seen in a couple of months once enough phones are effectively blocked and the repair shops have enough spare parts (I have no doubts that many stolen phones will be chopped up).

Update 22/01/2012: after a recent visit to Caracas I checked up on this issue. Seams like the actual bureaucratic burden does not let this policy to be correctly be implemented. I hope this gets better with time.

After checking with pidgin, which I use for other accounts, that my credentials were still working I found a post in the Ubuntu Forums that gave me a good solution:

$ sudo aptitude remove telepathy-butterfly
– Make sure you have telepathy-haze installed, if not
$ sudo aptitude install telepathy-haze
– Delete the accounts and recreate them with the new plugin

I’m not sure why this happened, but at least it’s working again.
Hope this helps someone else out there.

This is a workaround I found around in the Web:
Create ~/bin/ooimpress-edit or if you want to use it system wide /usr/local/bin/ooimpress-edit; and add the following code into it

#!/bin/bash
ooimpress -n “$*”
exit

Use it when ever you think you need it.  I set it up as default behaviour in the browser.

I decided to install the new and shiny Ubuntu 10.04 “Lucid Lynx”, but there is no way I want to affect my main partitions!! Why should I this is Linux after all, it can boot from a secondary partition I can even put the bootloader at the beginning of the partition to make it totally independent!! Having done that already with Backtrack 4, Ubuntu 9.10 (karmic) and CentOS 5.x it should be as easy as 1 – 2 – 3 (Or simple as… got Jackson 5 ringing in my ear right now).

So the solution I had in mind was just to add a new partition with parted, install there and add the following lines to the /etc/grub.conf in my Fedora partition:

title Ubuntu 9.10 (Karmic)
rootnoverify (hd0,6)
chainloader +1

The problem is that Ubuntu 10.04 ships with grub-2 (technically speaking 1.98) and it just doesn’t work the same way. After a couple of re-installs and hours later I came out with this blog with a really detailed review of the distribution and with the solution I needed:

title Ubuntu 10.04 (Lucid Lynx)
root (hd0,4)
kernel /boot/grub/core.img
savedefault
boot

Just to make sure your a attacking the right error, this is was I was getting: Error 13 invalid or unsupported executable format

Enjoy

After reading for a while I found out that de Mozilla Foundation built in this protection for “Cross-Protocol” scripting attack with a form of Port Banning.

To overide this protection use one of the following steps:

• In the user’s profile directory the all.js, add the following line at the end of the file user_pref("network.security.ports.banned.override", "1-65535");
• In the defaults/pref/ sub-directory of the installation directory (multi-user systems) add the following line at the end of the file user_pref("network.security.ports.banned.override","1-65535");
• Open a new window, in the address type: about:config and add a new entry of the type string with this name network.security.ports.banned.override and value 1-65535.

If you want to set free only one port change the range for that port o list of ports.

This is a topic that caught my eye a while ago and just found out it’s still an open issue.

According to their website:

SWIFT is the Society for Worldwide Interbank Financial Telecommunication, a member-owned cooperative through which the financial world conducts its business operations with speed, certainty and confidence. Over 8,300 banking organisations, securities institutions and corporate customers in more than 208 countries trust us every day to exchange millions of standardised financial messages.

So basically it’s the organization that manages the API’s and systems that make international banking work smoothly.

This Belgium based organization had it’s major databases in the US until an article in the NY Times aired that the CIA under the Bush administration had been data mining the database to find links to terrorism, after Europe protested the database was move to Holland.  So the issue now is that the US intelligence agencies want to keep having unlimited access to spy on EU Citizens using the usual terrorism joker card.

I think this is a big issue and should be handled a such.  There are some open questions I have to this deal:
What does a US or in fact any intelligence agency have to do with our financial records without a warrant?
Is every person in the world considered a potential terrorist?
Were are rights, are privacy?
While we’re at it:  How long is this data retained?  How is it guarded? Who makes sure it’s correctly discarded?

Benjamin Franklin summed this up better than I can ever try to:

They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety
