Abstract: The essay is about the importance of knowing about various security threats faced by mobile communication device users and the available free software to overcome the threats. The common and unique features of some of the standard security apps are discussed here and the conclusion is that companies cannot completely prevent security threats, and the users have to be alert in using their devices. The users are also required to upgrade their security systems periodically.

Introduction: As the mobile usage increases for various financial transactional purposes, the mobile devices are exposed to risks of increased attacks. All mobiles are susceptible to cyber-attack. Most digital security related solution providers agree that it is difficult to prevent security threats to mobile devices. Similar to viruses and spyware that can damage the operating system and data in a PC, there are many other security threats that can upset the mobile devices. The researchers have divided the threats to mobile devices into three major categories i.e. application oriented threats, Internet oriented threats, and network/physical oriented threats. Application oriented threats includes, malware, spyware, privacy threats and vulnerable apps. Internet based threats includes, phishing activities, browser exploits and cookie downloads. Network / physical threats include wi-fi sniffing, network exploits and illegal tampering of mobile device.

The two giant mobile operating system companies the Apple and Android have advanced many security features to their system. Even then the malicious hackers attempt to encroach into mobile devices and run their malware surreptitiously. The operating system companies have limitations to prevent entry of malware into the mobile phone as more number of users is inclined to install apps that have lesser security. Security is the least priority of many app designers and developers and their services have weak security features. For users, the security of their mobile devices is critical, as most of the serious transactions are happening over the mobile phones. It is important for th users to know more about the threats and what the companies are doing to overcome the digital security lapses.

A Review of Standard Mobile Security Software: Among mobile operating systems, Android is the most widely-used platform in the world (Teng, and Wen 2017). Hence, Android phones are the most likely targets of hackers and the users are required to install best security apps and antivirus systems. Because of the popularity of the Android, a Google service, the hackers are thrilled to break its security walls. There are many free security apps available to protect the mobile devices from attack. Some of the popular security tools are discussed below. The following account is a brief description of the free security apps available to the users and it describes the common and unique features of each of the apps.

Avast Mobile security: Avast is an antivirus giant that has experience in the industry for long time. It is much more than an antivirus scanner (Pieterse, and Olivier, 2013). For a mobile device, the Avast can block unwanted calls, provide a firewall to the data stored in the mobile and help the user to with anti-theft protocol. The user will be able to lock the phone or wipe out critical data when the dive is stolen or is missing.

The Avast app is available for free as well as paid version. The paid version is loaded with extra features.

One of the disadvantages of the free McAfee system is that it is supported by ads. The user is bound to see unwanted ads while using the mobile device.

Kaspersky Mobile Antivirus: Kaspersky has reputation on par with Avast, BitFinder, etc. There are many impressive features to the free version of mobile security apps. Because of its experience in defending digital resources, it has many common and unique features (Clarke, Symes, Saevanee, and Furnell, 2016). The common features include identification of malware, blocking of malicious sites, preventing malicious links from the screen. More than cure to the damaged device, the Kaspersky software focuses on the prevention aspect. Some of the unique features Kaspersky include the following.

  • The system can sniff out the stealthiest malware
  • The tool can not only block malware sites, but also harmful links
  • Block viruses
  • Scan Wi-Fi security weakness
  • Secure the users passwords

Discussion and Conclusion: Many mobile users consider that mobile device security is exposed to fewer security risks than a PC and many are not aware of the consequences of a besieged mobile device. Malicious software that can encroach into a mobile device can lead to serious personal losses such as misuse of bank accounts, phishing, etc. It is critical for the users to be alert about the security risks and take necessary actions (Omar 2017).

Companies that make the security tools agree that it is really hard to protect the entire range of treats, because the risk is not focused on to one aspect; it is fragmented. They recommend some common steps to prevent security breaches. First is to install a security system in every mobile device from a known service provider. Second is to update the software regularly, o that the latest threats also can be avoided. The search engines of Google and other social sites are not capable of preventing threats; hence all mobile users must have distinct apps for mitigating security threats. It is all about precautions and alertness about the digital security risks.
