The Nuances of Mobile Security

Mobile phone, especially a smartphone, is no longer simply a communication tool. Nowadays, more and more mobiles users and especially the business professionals use smartphones to plan and organize personal and official life as well.

However, on the flip side, this sudden increased dependency on technology is inflicting profound changes within data systems and is becoming a source of risk. Undoubtedly,  smartphones collect an increasing amount of sensitive data the access to which should be controlled to guard the privacy of the user and the organizations which inevitably become a part of the vicious circle.

Types of attacks:

1) Attack made through messages:

An attack can be made possible by sending an irregular block of text, thereby causing the phone to restart, leading to DOS attacks. For example, If you have a Siemens S55 OS and you have received a text message containing a Chinese character, it could lead to a denial of service as its not defined in the OS functioning.

2) Attacks made through Wi-Fi:

An attacker can try to eavesdrop on your Wi-Fi Connection to get information like your password. These types of attacks are not so common to smartphones, but they are very open to these attacks because quite often Wireless communication (Wi-Fi) is the only means of communication. With brute force attacks and attacker can easily access the requisite information. So, it is suggested to use WPA / WPA2 protocol instead of WEP.

3) Attacks made through Bluetooth connection:

These are one of the most common attacks wherein, the attacker can easily transmit a file and get the access to your device. Consequently, there is a dire need to protect your smartphone against such threats.
You will be shocked to know that in the last two quarters closing 2012, the number of unique mobile threats grew by 161%, according to a research. Such threats increase the probability of data loss, data thefts etc. So, the big question that arises is howcan this be controlled ?

Generic & effective ways:

An antivirus software can be installed on a device to verify if it is corrupted by a known threat, usually by SDS (Signature Detection Software) that detects the corrupt files.

Most of the smartphones these days are using Biometric Locks, which uses a technology to identify a person by means of her morphology (eye or face detection). In this case, only the primary user would be able to unlock the phone and so your data would remain secure.

Do’s and Dont’s:

> Do not be overly vulnerable
Do not believe in everything that is presented while downloading an app. A lot of information that is asked can be phishing or attempting to distribute a malicious code. Do check the reputation of that app before using.

> Be careful
Protect it by using simple gestures like – Lock your phone when not in use, do not leave your handset unattended. Also, do not store a lot of sensitive data on such devices.

> Look for the permissions granted to apps
Do ensure the privileges required by an application during installation and do not accept if the rights are inconsistent.

Albeit, it is not impossible to insulate your device against such threats completely, however, an intelligent and careful user can protect himself from sudden data loss or data theft.

Google Chrome Web Store – House Of Web Apps For Chrome Browser

Rather than going to Google Chrome Web Store, let’s first spill out some beans on Chrome Browser. Chrome browser is based on an Open Source Project known as Chromium which was released by Google in 2008. In same month Google publicly released Google Chrome along with support of 43 languages. After its launch, it topped browser charts and in months it plunged to the top spot in the world of browsers. Most of users liked its apps which were earlier present in toolbar forms in other browsers. But Google made it easy to integrate it with web apps which is the main reason behind its success story.

When this reason came under light, Google introduced Google Chrome Web Store - House Of Web Apps for Chrome Browser. Now all web apps are under one shed and users don’t need to crawl here and there for useful apps. According to Sundar Pichai, Google’s Senior Vice President for Chrome and Apps, Google Chrome now has 310 million active users.

Google Chrome Store was introduced by Vic Gundotra at Google IO in 2010. Google Chrome store is now a house of Chrome Extensions, web apps, themes, and other applications. The first batch of Web apps were free Google products and therefore, presumably, free of charge. These include Google’s ubiquitous services like Docs, Calendar, Mail, News, Maps as well as Picasa and Google Wave. But later on due to its popularity various other service providers like Pandora, Zynga Game developers, etc tried their hands into Chrome Extensions and gave users tremendous games which were earlier restricted to Facebook and other portals only, useful apps, etc.

Now you can download or find out various apps for one topic. Now there are apps for everyone for Business, for Education, Productivity, Lifestyle, Weather, News, etc.

In 2010 its user interface was not that good for easy navigation, So, Google updated its Web Store with new User Interface in 2011. Developers are now open to charge for their apps. Now developers can even earn by selling apps rather than only in app advertising. As of now users have download 750 million apps from the Chrome web store.

Due to its popularity and advancement, Google has also introduced Chrome OS which runs on Chromebooks. Chromebooks use Chrome Extensions like software on Windows.

So at last Google has built such an advanced platform for PC and other OS users through which users can do work without closing, minimizing and maximizing any window or file.

What is Firewall and How it Helps You?

The term “fire wall” originally meant, fireproof  wall which prevents the fire from entering  one place to another. The Internet is a very unsafe environment when viewed from a computer-security perspective. Firewall provides you Network security.

A firewall is a software program or piece of hardware that helps screen out hackers, virus, and worms that try to reach your computer over the Internet and steal your important data. Firewall checks every data packet and if it is harmful for the PC, it blocks that particular data packet. Now a days Firewall is necessary for every PC. It helps us in various ways -

  • If you use a computer at home, the most effective and important first step you can take to help protect your computer is to turn on a firewall.
  • Windows 7, Windows Vista, and Windows XP SP2 or higher have a firewall built-in and turned on by default.
  • If you have more than one computer connected in the home, or if you have a small-office network, it is important to protect every computer. You should have a hardware firewall (such as a router) to protect your network. You should also use a software firewall on each computer to help prevent the spread of a virus in your network if one of the computers becomes infected.
  • If your computer is a part of a business, school, or other organizational network, you should follow the policies established by the network administrator.

Tips to improve battery life of your cell phone

As cellphones become more powerful and capable of doing more, a notable tradeoff has been a decline in battery life. We all want high-performing phones that we can use to make tons of phone calls as well as run lots of apps, stream music, and surf the web which sucks the battery which further leads you to charge your phone again and again. But there are things you can do to increase the battery life of your phone.

  1. Turn off all off all unnecessary sounds : One of my biggest pet peeves is how most phones these days come with keytones on. Do people really like hearing their phone beep, strum a musical note, or chime every time they press a button? You might like it, but ask your neighbor. Plus, turning these off will save you a good amount of battery juice.
  2. Use either a ringer or vibrate : but not both. We understand if you’re in a concert or loud party you want to increase your chance of actually realizing your phone is ringing, but other than that, pick one or the other. There’s no need to have your ringer all the way to the point where it has both the sound and vibrate alerts active, so we would recommend against it. If you’re worried about not hearing your phone when it’s on vibrate, put it on a table and we promise you’ll hear it.
  3. Adjust your phone’s brightness: While it’s nice to have a super-bright screen, you’ll pay for it with battery life.  If your phone doesn’t default to auto brightness, choose it as your setting and the screen will adjust itself depending on the lighting conditions.
  4. Lock your phone : While this may seem like common sense, make sure your auto-lock setting is as low as possible given your needs (iPhone users : Settings, General, Auto-Lock and set to 1 minute).
  5. Clean the battery contacts on the battery and on the phone : Over time, contacts may accumulate dirt which reduce the efficiency of energy transfer. Clean them with a cotton swab and rubbing isopropyl alcohol. If the contacts are two different metals, such as gold and tin, accelerated corrosion known as “galvanic or bi-metallic” occurs. Cutting the corrosion from the contacts often requires solvents, such as acetone or nail polish remover. Be careful: these solvents dissolve plastic, so use a Q-Tip to avoid damaging the battery housing or the phone.

What is GHz in a Mobile?

One GHz represents 1 billion cycles per second. The speed of microprocessors, called the clock speed, is often measured in Gigahertz. For example, a microprocessor that runs at 200 GHz executes 200 billion cycles per second. Each computer instruction requires a fixed number of cycles, so the clock speed determines how many instructions per second the microprocessor can execute. To a large degree, this controls how powerful the microprocessor is.

Now days it is necessary that a Smartphone must have atleast 1GHz processor in it because now everyone is using smartphones for their daily work which they were doing on laptops earlier. Day to day, the load of work is increasing on smartphones so it is necessary that smartphones must have atleast 1GHz processor. We have made a list of some of the best smartphones which are above 1GHz processor.

  • Samsung Galaxy Note 2
  • Motorola Razr Maxx
  • Samsung Galaxy S Duos
  • HTC Desire VC
  • Samsung Galaxy S3
  • Sony Xperia U
  • Samsung Galaxy Ace Plus, etc
