Browser fight continues : CHROME continues topping too!!!


1.    Not long back we all have seen or might have experienced when violent and pornographic images were fed across facebook profiles of FB friends without the knowledge of the online FB user when he used to simply click on a tempting link!!!!All that happened owing to so many malwares but the exact launching vulnerability was indeed in the BROWSER!!!!!

2.    The openweb is full of options for seemingly good browsers viz Mozilla Firefox, Google Chrome, and Microsoft’s Internet Explorer. But who is the best?.....though when u google u find so may individual claims but third party tests are always welcome on such issues...specially when they have huge evidence to support....like few years back I posted on ACID3 test for the browsers...this one comes from Accuvant...and its actually huge in terms of a conclusive report that's 139 pages in toto......:-)

3.   The full report can be accessed by clicking here...so the Accuvant study revealed that Chrome ranks as the most secure web browser when compared to Internet Explorer and Firefox. Interestingly, German government named Chrome the most secure browser, perhaps lending weight to the study. 

4.   The criteria to test these browsers included factors like ASLR,GS,Sandboxing,JIT Security etc as shown below :

DAEDALUS : Monitor Cyber-Attacks Realtime 3D way


1.    Whether it is the Die Hard ver 4.0 movie scene or Mission impossible recent one or any hi tech cyber movie....we have have all seen the mega sized dark halls equipped with gigantic screen displaying all sorts of real time ridiculous hacker related information and monitoring tracks of the enemy or the protagonist....so how good or effective or even real are these in the real sense....can some thing like these seen and shown over years on the silver screen be REAL....yesss...first watch this video and then read few points as bought out below :


2.   A company in Japan named NICT just unveiled a system dubbed Daedalus that will revolutionize the way companies and even countries can monitor cyber-attacks in full real time 3D representation.The key features about this is bought out as below :

- Daedalus is not only a way to monitor cyber-attacks from outside, but also what’s going on inside it. 

- So if someone receives an email with a virus for example, the system can quickly identify the IP address that is currently spreading it and shut it down immediately.

- The NICT recently gave a demonstration and tracked 190,000 IP addresses in real-time  

- Daedalus can monitor multiple entities at once and get notified, once again, via 3D graphical representation when a cyber-attack occurs. 

- This is not only when it happens, but instantly where it happens and who the attacker is.

3.      So when the objective is envisaged on a higher scale....ie the complete global internet monitoring.....will this be the start to control spam(90% of mails exchanged on the web is spam)....or will this be able to control cyber attacks across.....well not a bad start to a start whose objective is MISSION IMPOSSIBLE type...another thing that may have come to your mind is about the name...of all what does Daedalus mean?...well in Greek mythology, Daedalus means "Clever Worker"

SOLVED: VLC installation Issues : FEDORA 18

1.      After installation of the spherical cow Fedora 18 64 bit on my machine,there was this popping message while i tried installing the VLC media player :


GPG key retrieval failed: [Errno 14] Could not open/read file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmfusion-free-fedora-18-x86_64


(CLICK TO ENLARGE)

2.    But this could be solved as shown below :

su -c 'yum localinstall --nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-18.noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-18.noarch.rpm'

and now do 

yum install vlc

Like in PATCO case,DO OUR BANKS GUARANTEE CYBER SECURE ACCOUNTS ?

1.   Suppose you have a SBI or HDFC or ICICI Bank or any bank account and you keep doing your regular transactions via their internet banking services like you pay your electricity bills or your mobile or phone bills etc.So ALL is WELL till every thing is going as expected.But then one day you realize that there were transactions that happened without your knowledge or worse some money gets siphoned off without your permission.....Now a journey starts......wherein the account holder will keep expediting with bank of what happened,why it happened,when will he get his money back???? and on the other hand bank will keep trying to prove that it is you or the account holder who acted irresponsible in his transactions and thus became the victim....the typical tu tu....mein mein.....

2.    Keeping this typical story in the background,now just think that did u ever make a attempt to know of what bank standards are maintained in respect of IT Security infrastructure....does bank conduct third party audits seriously?..... in fact the list to know answers to all these questionnaire pertaining to IT security issues of the bank will end up getting complex which would go beyond the understanding level of a typical user...so the simple question is WHO GUARANTEES A SECURE IT INFRASTRUCTURE for a BANK?...is it the bank itself that says " I am secure " or some one else has some authority or some standard that guarantees security....ie Can your savings bank account ever be guaranteed for being HACK FREE?Although the immediate answer in the current setup is sadly "NO"...but there is good news here....for this u need to read this article on " PATCO FRAUD CASE DISPUTE "

3. Brief of this good news goes like this in a Short ppt

How to find if latest kernel version is running on my Linux system?

Simply type in these commands and the result in both the cases should match.....


rpm -qa kernel |sort |tail -n 1

uname -r

Note: If you got kernel update or run older kernel than newest installed then reboot:

reboot

Output of each commands version numbers above should match....for example in my case the out put is shown as below :

[duqu@localhost ~]$ rpm -qa kernel |sort |tail -n 1
kernel-3.6.10-4.fc18.x86_64
[duqu@localhost ~]$ uname -r
3.6.10-4.fc18.x86_64

Upgrading Fedora 17 to Fedora 18

1.   Like me so many of you would have been waiting for the final release of Fedora 18 spherical cow...but at the same time when u see it released u have so many links to move around on how to upgrade from 17 to 18 but u keep ending up with previous one....i went through the same for past hour...:-)

2.  The only set of commands Fedora 17(only) users need to put in are these :
Reach the Root first with the password ie 


su -
*******(ur password)
su -c 'rpm --import https://fedoraproject.org/static/DE7F38BD.txt'


su -c 'setenforce Permissive'

su -c 'yum update yum'

su -c 'yum clean all'

su -c 'yum --releasever=18 --disableplugin=presto distro-sync'

su -c 'rpm --rebuilddb', or rpm -qa will not work due to a upgrade of rpm

3.   For me the upgrade is around 1.6 G as seen in the screen shot below :


4.   Mine is upgrading on way....another few hours should be ok....:-) all the best for your upgrade
