security is a concept that has gained a lot of importance ever since the launch of the first mobile Operating System, Symbian, which was launched by Nokia. It is continuing to gain significance with the massive use of the Android Operating System.

This mobile device security tutorial will take you through the simple and practical approaches to implementing mobile device security techniques.

With the number of mobile device users increasing year after year, the need for mobile device security is also gaining ground. Mobile phones have now become vulnerable because of the rapid progress in the mobile phone industry and the introduction of cloud services and apps.

Introduction to Mobile Device Security

This mobile device security tutorial deals with mobile security concepts mostly from a practical point of view. The estimated number of mobile devices globally is around 5.8 billion, which is thought to have grown exponentially within 5 years and is supposed to reach nearly 12 billion within 4 years.

Hence, it will be an average of 2 mobile devices per person on the planet. This makes individuals fully dependent on mobile devices with their sensitive data being transported all over. As a result, mobile device security is one of the most important concepts to take into consideration.

Mobile device security as a concept deals with the protection of mobile devices from possible attacks by other mobile devices, or the wireless environment in which the device is connected.

Following are the major threats regarding mobile device security

  • Loss of mobile device: This is a common issue that can put at risk not only you but even your contacts by possible phishing.
  • Application hacking or breaching: This is the second most important issue. Many of us have downloaded and installed phone applications. Some of them request extra access or privileges such as access to your location, contact, and browsing history for marketing purposes, but on the other hand, the site provides access to other contacts too. Other factors of concern are Trojans, viruses, etc.
  • Smartphone theft: This is a common problem for owners of highly coveted smartphones such as or Android devices. The danger of corporate data, such as account credentials and access to email falling into the hands of a tech thief is a threat.

Mobile Security Attack Vectors

This is a way or method that mobile hackers use to gain access to some other computing tool or network to inject a “bad code” regularly referred to as the payload. This vector allows mobile hackers to exploit system vulnerabilities. Many of those assault vectors take advantage of the human element as it is the weakest point of this system.

Following is the schematic representation of the attack vectors process which may be many at the identical time used by a mobile hacker.

Mobile Security Attack Vector Examples

  • Malware
    • Virus and Rootkit
    • Application modification
    • Operating System modification
    • Data Exfiltration
    • Data leaves the organization
    • Print screen
    • Copy to USB and backup loss
  • Data Tampering
    • Modification by another application
    • Undetected tamper attempts
    • Jail-broken devices
  • Data Loss
    • Device loss
    • Unauthorized device access
    • Application vulnerabilities

Consequences of Attack Vectors

Attack vectors are a hacking process as explained and it is successful, following is the impact of mobile device security attack vendors on your mobile devices

  • Losing your data: If your mobile device has been hacked, or a virus introduced, then all your stored data is lost and taken by the attacker.
  • Bad use of your mobile resources: This means that your network or mobile device can go into overload so you are unable to access your genuine services. In worse scenarios, it is used by the hacker to attach another machine or network.
  • Reputation loss: In case your Facebook account or email account is hacked, the hacker can send fake messages to your friends, business partners and other contacts. This might damage your reputation.
  • Identity theft: There can be a case of identity theft such as photo, name, address, credit card, etc. and the same can be used for a crime.

Mobile Device Attack Vulnerability

Infecting your Mobile Device

Infecting the device with mobile spyware is performed differently for Android and iOS devices.

  • Android: Users are tricked to download an app from the market or a third-party application generally by using social engineering attack. Remote infection can also be performed through a Man-in-the-Middle (MitM) attack, where an active adversary intercepts the user’s mobile communications to inject the malware.
  • iOS: iOS infection requires physical access to the mobile. Infecting the device can also be through exploiting a zero-day such as the JailbreakME exploit.

Backdoor Attack

Installing a backdoor requires administrator privileges by rooting Android devices and jailbreaking Apple devices. Despite device manufacturers placing rooting/jailbreaking detection mechanisms, mobile spyware easily bypasses them

  • Android: Rooting detection mechanisms do not apply to intentional rooting.
  • iOS: The jailbreaking “community” is vociferous and motivated.
  • Bypassing encryption mechanisms and exfiltrating information

Spyware sends mobile content such as encrypted emails and messages to the attacker servers in plain text. The spyware does not directly attack the secure container. It grabs the data at the point where the user pulls up data from the secure container to read it. At that stage, when the content is decrypted for the user’s usage, the spyware takes control of the content and sends it on.
