Device security, also known as cybersecurity, is the practice of protecting devices from threats like data breaches, malicious software, and unauthorised access.

Requirements vary from device to device, so whether you’re using a mobile phone, laptop, PC, or tablet, you will need to consider different security options to protect your device — and your data. This protection comes in the form of strong authentication, restricted network access, and secure password management.

Where should you start? We’ll take you through how to secure a device, and top tips to stay safe online.



What are the consequences of poor device security?

In a worst-case scenario where your devices are left totally unprotected, you may suffer from financial losses, identity theft, and unauthorised access to personal data.

In corporate settings, poor device security can also manifest through the loss of sensitive company information, data breaches, and expensive recovery efforts.

Taking device security seriously

Cybersecurity threats are always on the horizon when you browse online, with ransomware attacks in the UK increasing by 70% in 2020 alone. Device security is essential to protect both personal and business data from cyber threats and attacks.



Types of device security

There are several types of device security you’ll need to cover to stay safe:

1. Antivirus/antimalware software

Antimalware tools can scan for — and remove — files that would otherwise harm your device or steal your personal data.

For example, if you install Norton™ 360 Premium antivirus software on your device, it runs in the background and keeps you protected online. If you accidentally download a file that may be infected with a virus or malware, Norton will notify you before any harm can be done.

2. Firewalls

A firewall acts as a barrier between your computer and potential threats online. It will inspect any user’s IP address and port numbers before they can access your network. This means unauthorised users can’t access private networks unless you specifically allow them.

3. Encryption

Encryption protects your information using mathematical models. Effectively, it converts your data into unreadable code that criminals cannot easily access. It’s especially useful when documents are in-transit or hosted online, such as on the cloud.

This way, if documents are stolen or lost, the encrypted data is still safe and cannot be used for malicious purposes.

4. Two-factor authentication

Two-factor authentication (also known as 2FA) gives you an extra layer of protection by requiring two forms of verification before granting access to your device, account, or data.

For example, you might use a password to log into a social media account, but with 2FA you might need to provide a verification code from text or email, or provide a fingerprint to access your account. Even if scammers get hold of your password, they still can’t access your data without the second stage of authentication.

5. Device updates

While not everyone likes the time it takes to update their device, it’s an important part of your device security. Updates can:

  • Make sure you always have the latest security protections installed

  • Add new security features to make you less vulnerable to malware, ransomware and viruses

  • Update or ‘patch’ any flaws from the previous version, leaving you less vulnerable overall



Essential tips and best practices for device security

As we mentioned, device security looks different depending on the device you use. Here are some best practices to make sure your whole household is covered:

Mobile devices (Android/iOS)

What is the best way to secure a mobile device? Mobile phones and tablets can be protected in several ways, such as following best practices for password security. Other ways include:

  • Installing security and antivirus apps

  • Install mobile device management software to track the location of any device and lock or wipe sensitive data remotely

  • Always use a VPN when logging into unsecured public WiFi networks

  • Update your device and apps when needed to keep your security up-to-date

Windows and macOS laptops

Device security for laptops involves creating ‘safety habits’ that keep things running smoothly.

  • Encrypt your harddrive/disk with a software like BitLocker for Windows or FileVault for macOS

  • Backup your data using a cloud service - this means you have access to precious files even in the event of a cyberattack

  • Enable built-in firewalls and other security settings, such as Windows Defender

  • Keep your laptop, operating system, and all relevant apps updated

  • Install anti-virus software like Norton™ 360 Premium to enable real-time protection

Internet of Things (IoT) devices

Devices that use AI or machine learning can be classified as ‘IoT’ hardware. These modern devices still need to be protected, as they connect to the internet in order to perform their core functions.

In fact, many IoT devices are not built with strong security features, so following these steps is especially important:

  • Update the software regularly for protection against the latest threats

  • Avoid using the same password across all your devices. Instead, use different, strong passwords for each 

  • Consider using a separate network for IoT devices to limit an attacker's access if they do manage to infiltrate the system



Understanding the importance of good device security

Following the steps above will help keep your personal and business information safe from cyber attacks, and data breaches. Basically, practising good device security will make you less open to cybercrimes like fraud and extortion.



FAQs about device security

<H3> What is the best way to secure my mobile device?

There is no single way to protect your mobile device from those with malicious intent. Instead, you should follow these best practices:

  • Use strong lock screen security

  • Avoid using public WiFi

  • Use an antivirus app

  • Use a password manager

  • Ensure your home network is set up securely

How can I ensure my computer is protected from viruses?

There are five essential steps to protect our computer from viruses:

  1. Install antivirus and antispyware software, such as Norton™ 360 Premium

  2. Enable firewall protection

  3. Use strong and diverse passwords

  4. Update your software regularly

  5. Don’t click links from unverified sources

What should I do if my device is lost or stolen?

Hopefully you followed the steps we covered in this article, so you can:

  • Lock your device remotely

  • Change your passwords

  • Track your phone’s location

Otherwise, you should monitor your account activity and file a police report as soon as possible.

Is it safe to use public WiFi?

Public WiFi is not always safe. If you connect to an unsecure network, attackers can steal your passwords and personal information, as well as infect your device with malware. Never connect to public WiFi without using a VPN and antivirus software.
