Mobile Device Security

Mobile device security is the use of method and  practices to secure the data and other information stored on the mobile devices, such as smartphones and tablets Securing the data is one of the major concerns of mobile technology due to heavy use of mobile devices. Common mobile security issues are data loss or mobile theft In these conditions, the users not only lose theft mobile phone, but also lose the vital data and sensitive information stored on it. Device data leakage to untrusted party is another issue that victim faces on losing his device.

Need of Mobile Device Security

Hackers are ready with every possible trick to get an access into the users’ mobile device. Hence the mobile device security is a must to protect the data from hackers. There is no shortage of people, who breach the security norms to exploit mobile users and earn profits. The recent introduction of mobile wallets has evoked hackers to increase the crime in the form of virtual pickpockets.

Though these devices are provided with protection standards like encryption and password security, the users must be aware of the security threats and ways to avoid them.

Mobile Operating System

An operating system especially designed for mobiles devices to allow them to run applications and programs is called a mobile Operating System (OS) when the power button on a mobile device is pressed, the mobile OS loads the necessary files to run the OS and shows the home screen filled with icons of different applications (or apps). Activities like managing phone calls, connecting with wireless networks, web browsing, exchanging text messages and executing other applications are managed by the mobile OS. Some of the Mobile Operating Systems that are used globally are:

iOS: Owned by Apple, iOS is a mobile operating system specially designed for Apple’s hardware. It is installed on devices, such as iPad, iPhone and iPod Touch and has a direct manipulation based user interface. It operates using multi-touch gestures to control elements such as buttons, sliders and switches.

Android: Owned by Google, Android is an open source operating system designed for touch screen mobile devices. The OS is based on the Linux kernel and allows developers to make programs as per their choice by accessing unlocked hardware. It operates using touch gestures to control actions like swiping, pinching, tapping and entering text using the virtual keyboard.

Windows Mobile: Owned by Microsoft, Windows Mobile is a mobile operating system designed for smartphones. Windows Mobile OS can be recognised by tiled set up and dubbed metro, through which tiles can be moved and interchanged using the metro. Users can browse the web using mobile-optimized version of Internet Explorer, known as Edge in Windows 10 Mobile.

 

IMEI Number

IMEI (International Mobile Equipment Identity) is a unique number, which is used to identify mobile handsets (using UMTS, GSM and LTE networks) or devices which connect to a cellular network. IMEI is as important as the phone’s operating system and is printed on every phone inside the battery space. There is also a code that you can enter and display the IMEI number on the handset screen using USSD. This code varies from operator to operator.

IMEI number is also used to prevent the threat of mobile theft. GSM networks use the IMEI number to identify legal devices and can block the stolen phone from accessing the network. The victim whose phone is stolen can call his network provider and ask them to blacklist the phone by providing them the IMEI number to prevent the device from being misused.

Role of IMEI Number

An IMEI number (eg. 568438126755154) is useful for many events, such as:

  • Mobile phone usage can be tracked by cell phone provider using IMEI number.
  • Subscribers can be identified using IMEI number.
  • Gadget type can be recognised using IMEI number.
  • Remote device can be easily disabled using IMEI number if stolen.

This makes it very easy for the hackers to get the crucial information of user by gaining access to their mobiles. By accessing a single device, the hacker can fetch the information of multiple accounts.

Theft and loss: Mobile devices are loaded with a lot of personal information like pictures, emails, social media accounts, banking apps, telephone contacts, important files and sometimes even login details of accounts. By merely losing a device, the user can lose all the data and becomes susceptible to online threat.

 

Unmanaged applications: It is advisable to keep the applications on the phone updated and managed. Failing this, user can invite hackers to intrude in their systems and get access to data.

Absence of mobile firewall: Due to non-availability of firewall on mobile devices, they are open to hackers via untrusted communication ports. In return, this puts mobile and sensitive information on high risk.

 

 

Mobile Malware

One of the biggest threats to smart phones; mobile malware is a malicious software that collapses the system by targeting wireless-enabled PDAs (Personal Digital Assistants) and mobile phones. They also lead to leakage or loss of private information. Because of the excessive and common use of PDAs and wireless phones, it has become very difficult to safeguard them from risks such as virus, malware and electronic attacks.

Mobile malware is intended to exploit the mobile operating system’s vulnerabilities. It collects confidential information and user data. It is specifically designed to deactivate a mobile device and remotely control it by allowing a malicious user to enter it to snip private data from the device. With the increasing competition and trends, high-profile mobile malware is increasing in strength and number. Targeted attack is one such attack, wherein the attacker makes all possible attempts to break the security measures of any particular company or person.

Android is the most widely used operating systems these days and this makes Android mobile operating system more vulnerable to malware attack, rather than iOS and Windows OS. Root malware is another common malware attack, inhere the attacker gains administrative rights and digs into the data of victim’s phone without their permission. Therefore, it is advisable to keep the mobile operating system updated to the latest version, which will minimize the risk of mobile malware attacks.

Vulnerabilities of Mobile Applications

The discussion regarding the security of mobile often ends up including the Smartphone, operating system and privacy settings. However, if the problem is analyzed logically, it is actually the mobile application which is the major source of attacks. No matter how good the app performs and how user friendly are its features and functionality; the application would be of no use if it cannot secure the crucial mobile data. Below is the list of some of the common vulnerability of mobile applications:

Insecure data storage: If the data is not stored in secure manner, the user can put the information at risk. Apart from synced cloud data storage apps, there are several mobile applications that promises data storage feature with data hiding function. This may entice cyber criminals to access the sensitive data by developing similar apps and malware. Users must avoid the myths that the data itself is protected on their mobile devices.

This may entice cybercriminals to access the sensitive data by developing similar apps and malware. Users must avoid the myths that the data itself is protected on their mobile devices.

Improper transport layer protection: Whenever the users search for any information on the Internet, it interacts with the remote server that receives the device request, looks for the requested information and sends it to the client. During this exchange between server and mobile device, the transmission must be protected. Avoiding this practice can open the doors for hackers to fetch data from insecure communication.

Poor authorisation and authentication: If authorization is not handled properly, even a good authentication mechanism can cause issues. Mobile users must make it a practice not to access the data that is not meant for them. Mobile apps only trust the client side authorization, which can come out as a drawback. Gullible mobile users may trust any server request or skip the authorization process for quick execution of the app. This could make the mobile device prone to attacks. Such risk can be minimized if the server side authorization are properly analyzed and checked.

Broken cryptography: Considering that the system is protected if the cryptography is in Place is a misunderstanding. Hackers remain active in solving and breaking even the strongest of cryptography techniques. Predictable keys, short protection Codes, cryptography type and weak ciphers are some of the failures. Incorporating the latest secure encryption technique that is not yet solved can prevent the mobile device from hacking.

Threats Associated with Bluetooth Devices

Not just the installed mobile applications, but also the installed software can cause security issues on a smart phone. Bluetooth is a perfect example to explain this case.
