Why Mobile Devices Are So Hard To Secure

Why Mobile Devices Are So Hard To Secure

IT security is difficult no matter what the platform — because software is imperfect, complex and constantly changing. However, there are three key factors which make securing mobile devices even more challenging.

This might seem like a blindingly obvious statement, but it remains the single biggest issue for securing mobile devices: the very fact of their mobility. Employees are generally quite unlikely to leave a server sitting in the back of a taxi, but that’s a hugely common scenario when it comes to laptops or smartphones. Physical access to devices makes them more vulnerable. There are absolutely strategies you can take to minimise this risk, but you can never eliminate it entirely.

User Control

Mobile devices such as phones and tablets are often owned by users and not directly connected to corporate networks, relying on specific logins for individual applications rather than a broad network-wide login. It’s also rare for them to be running a standardised platform: phone owners will often reject enforced updates (“I don’t have time to download that! I haven’t got any spare bandwidth! I can’t be without my phone for that long!”), so security vulnerabilities can remain in place long after they have been identified and patched by the developers. Most of those problems can be addressed through a mixture of security software and policy, but they need to be recognised and acknowledged before you can do that.

Security Is An Afterthought

While the situation isn’t quite as dire as when smartphones first became popular, it remains the case that if there’s a choice between making a phone easier to use and making it easier to secure, phone software designers will invariably opt for the former. Even when there are useful security features built-in — such as requiring a password or setting up remote wipe capabilities — it’s usually up to the owner to activate these, and many people don’t ever get around to it. This isn’t true to the same extent with laptops, but those can present a different type of challenge: it’s comparatively simple to export data from laptops, for example.


  • Practice turning on the security features of your phone. It’s not made just for a design, it’s made for your own protection. Encrypt your data and regularly back up your data. Visit only reputable sites and apps to avoid malicious malware and watch out for prompt and warnings to allow software to install or run. Just think of it that your Smartphone is like your wallet, keep it safe and on your person at all time.
