Windows XP is dead, Why not switch to Ubuntu Linux?

Microsoft has stopped supporting its 14 year old Operating system - Windows XP this month(April 2014). No new updates or fixes and security updates will be released to XP machines (Unless you are in government and ready to pay heavy charges). Here are is Microsoft announcement on XP

While XP was great for personal use, it is one of the least secure Operating System(OS) today.  The most vulnerable OS by Microsoft and this is due to its single-user architecture.  Microsoft has surely moved ahead with lessons learned and improved with Windows7 and Win8+ . Its still is most exploited OS on planet due to its design.

Time to switch to Ubuntu Linux:
With no updates on XP from Microsoft, its time for you to switch to better OS. Either upgrade to Win7/Win8 if your machine supports and ready to throw away some cash, OR try out new Ubuntu Linux 14.04.

Ubuntu ( is Linux distribution which is FREE for use.  It’s a ge…

Why you need to understand mobile app permissions ?

Android has been successful due to huge array of apps available and ease of download for users.  Open nature of android helps app developers do develop various kinds of apps and do magic. Installing an app shows permissions required for an app and that gives us a hint what this app can do/access from you smartphone/tablet

App permissions are access that an app is requesting before you download and install it. If you grant the access, app downloads and has all required permissions to run. No permissions are asked thereafter unless additional permissions are required to update newer version from Google play.

Android platform provide granular permission set for apps. Based on what an app does, it defines which permissions are required and does let android-platform know about those.  As a user you get to know these permissions when you opt to install the app and before you download it.

It depends on app what permissions it needs. If you are just installing a game, then it may ideally not …

Use Bookmarks for Bank websites!

Online banking is preferred way for bank transactions and we hardly visit bank building. Most banks do provide android/iphone apps  to take it further. Bank websites are here to stay and do provide rich set of services for customers; and here lies the security issue. You need to protect you identity while logging in and prevent using your credentials on any other fake websites.

Disable apps that you don't use and can't uninstall

You got a brand new Android mobile ? Great. Got lots of app pre-installed ? Yeah.  Mobile manufactures (Samsung/LG/Asus/HTC/Nokia and others) pre-install loads of apps by default. They partner with other app developers to promote apps and make money in turn. Great business sense to pre-install and get people use those apps with ease.

There are apps that are common and people do install it eventually (e.g. Gmail/facebook/Whatsapp). It make sense to install it by default and make it available for people to start using right away on their new phone.  However there are ton of other apps  that mobile manufactures pre-install and that is annoying to users.

As a user you may never use these pre-loaded apps. Just an example, I got Samsung S4 (from phone service provider) and it came with 80 odd apps, out of that I never ever used 40 apps!  That's huge set of apps pre-loaded. It may vary based on which phone you buy, however its obvious that new mobiles does comes with good number of pre-…

Use "Private browsing" mode for security reasons

All modern browsers support "Private Browsing" mode or "Incognito" mode as in Google Chrome. No traces are left behind when you browse in private mode. No history, no temporary files, no web cookies to track users and no cache. Files you explicitly download do remain.

Private browsing mode shield you only on local machine; your Internet service provider or your company can still know what your are browsing. Private-browsing still make sense from security point as explained below.

Here are good reason why you should use private-browsing mode 

Public computer usage - You are using a public computer and accessing your email/Facebook or bank accounts. Use private mode. No history, no passwords will be stored back for others to use.
Temporary login to friends machine - Logging in from friends/colleagues machine to do a quick email/Facebook/etc. check. Leave no traces for friend to see.
Login to bank website - Accessing bank account for any transaction? prefer private browsi…

Securing your account with password only? That’s not enough anymore - Use two-factor authentication

Using userID and password only to login to your account is old method to ensure security to your account(email, bank, facebook, etc.). It has been reported numerous times that passwords can be stolen, leaked, cracked, captured, sniffed & guessed. Bad guys (may be your own people with bad motives) are trying hard to get your password and get into your account to steal data/money/identity/photos.

You need to protect your account with something more than just UserID and password. Strong password is not enough to protect your account and you need to go beyond that to make your account secure.

What is two factor authentication ?
In simple terms you can consider two factor authentication as "Two Locks" for your account. You need to open both the locks before your get into your account. And to open two locks you of course need two separate keys.

Two factor authentication is security process in which you use your userID+Password and physical token. Its "something you know&qu…
