HACKERS & TERRORISTs ARE NOT IDIOTS

1.    You have to go through all the classes from 1st to 12th standard to be eligible to be admitted into a college.But does the Govt think so? sorry for a bad connotation...I will come to the point...

2.     Recently,in the name of cyber security preparedness,the Government,in a first of its kind, conducted a live competition between two spy systems developed by reputed tech arms of India's national security apparatus. Expectantly...(though not from the Govt point of view)...both failed to capture 100% internet data traffic, one system even crashing a number of times during the test.

3.   Point wise summary comes as follows :

- Competition held near the Air Force Station, Arjangarh.

- Conducted between a system developed by Centre for Artificial Intelligence and Robotics (CAIR)@'Netra' and NTRO's @'Vishwarupal'@developed in collaboration with a Paladion Networks.

-  A high-level committee(???) declared Defence Ministry's 'Netra' system a winner.

-  During conduct of the test , "Vishwarupal", crashed a number of times and had to be restarted. 

-  Both the systems did not capture entire internet traffic passing via its probes installed at Sify Technologies premises in Delhi. 

-  Both could return results only after repeated attempts and that too with a high latency@15 minutes.

-  Netra will now be made a robust system, to scan all tweets, status updates, messages, emails, internet calls, blogs and forums for keywords such as 'attack', 'bomb' and 'drill'

-  The committee also directed NTRO, to wrest the design and source code of its system, exclusively from Paladion, due to a risk on national security.

4.   Now if the criteria of search is still to look after key words like Bomb,drill,attack etc,I think its time to rethink again.No real world terrorist would actually use similar words since they think much ahead and are sadly making use of the technology more efficiently then the other side.Are we not aware of latest unbreakable cryptography,stegnaography and other such related field standards?.....the SRS for building such a system should be exhaustive,based on dynamic@changing and improving technology standards.

5.   We are a country who is unable to exploit the inhouse talent and strength.We still keep searching and associating ourselves with outside country companies....We are already late...and we will be more late!!!!

YUM INSTALLATION STEP BY STEP : RHEL 5

1.   Recently inserted one video screen recording of how the yum installation is conducted in RHEL 5.The step wise command summary goes like this :


  130  cd /media/RHEL_5.1\ i386\ DVD/
  131  cp -av /media/RHEL_5.1\ i386\ DVD/images/ /var/ftp/pub/
  132  cp -av /media/RHEL_5.1\ i386\ DVD/RPM-GPG-KEY* /var/ftp/pub/
  133  cd /var/ftp/pub/Server/
  134  rpm -ivh createrepo-0.4.4-2.fc6.noarch.rpm 
  135  createrepo -v /var/ftp/pub/
  136  createrepo -g /var/ftp/pub/Server/repodata/comps-rhel5-server-core.xml /var/ftp/pub/

Installing Guest Additions in Virtual Box : RHEL 5

1.  In variably I have been using various window OS trials for experimenting in Virtual Box....and yes it is easy to use....but try it out with an RHEL 5.....it became a small fight for me at least.....how i solved it goes like this...

(a) First tried with this :

./VBoxLinuxAdditions-x86.run 

and i was given this error message :

bash: ./VBoxLinuxAdditions-x86.run: /bin/sh: bad interpreter: Permission denied

(b)....the answer is actually this :

sh VBoxLinuxAdditions-x86.run 
or 
bash VBoxLinuxAdditions-x86.run

and the output looks something like this

[root@localhost VBoxGuestAdditions_4.1.8_75467]# ./VBoxLinuxAdditions.run
Verifying archive integrity... All good.

Blue Tooth handshakes Wifi: Here Comes BLUE FI

1.    Here some thing when technology meets technology....so till date I used to identify Blue Tooth with  proprietary open wireless technology standard for exchanging data over short distances and WiFi with 802.11 IEEE standard...now when these two get mixed we get a BLUE FI.

2.  As per a paper "Blue-Fi: Enhancing Wi-Fi Performance using Bluetooth Signals by Ganesh Ananthanarayanan" Blue Fi is a system that predicts the availability of the Wi-Fi connectivity by using a combination of bluetooth contact-patterns and cell-tower information. This allows the device to intelligently switch the Wi-Fi interface on only when there is Wi-Fi connectivity available, thus avoiding the long periods in idle state and significantly reducing the the number of scans for discovery.Now the best part about this is that when I searched something on BLUE-FI,two prominent google searches included a Paper as mentioned above by an Indiuan and also the first implememntation in India at Bangalore City Railway Station that became the first in the railway network to offer BluFi.

3.   The passengers at Banglore railway station would be able to get Internet access, by sending their mobile numbers through the Wi-Fi registration portal. The passwords would be sent through SMS. A passenger could use Internet for 45 minutes; if he wished to continue, he had to start a fresh session....sounds a gr8 start....and promising

BOY in the BROWSER attack

1.  Funny names keep propping up...and keep getting accepted too...first it was Man in the Middle attack....then Man in the Browser...and now comes Boy in the Browser attack....actually, is a trojan that reroutes its victim's web traffic information through an attacker’s proxy site.  ....a cool video here explains it in a simple language....
