For most people, the ease of setting up an office anywhere is what makes remote work appealing.

‍

Working from anywhere, like a cafe, an airport lounge, or a hotel lobby, is incredible, but this convenience comes with hidden risks. Public networks, shared spaces, and unsecured devices leave your work and your data more exposed than you might think. 

‍

Unlike corporate offices designed with controls such as firewalls, access controls, and dedicated IT teams, your mobile office is only as safe as the precautions you take. The good news is that protecting yourself doesn’t have to be complicated. Let's talk about how to protect your work and your data from prying eyes while working remotely.

‍

Understanding the dangers: Your biggest remote work risks

Before you can protect yourself, you need to know what makes you vulnerable. Here are some of the most common threats you'll face whilst working remotely.

‍

1. The minefield of public Wi-Fi

Public Wi-Fi is one of the biggest threats to remote work security. When you connect to a publicly available Wi-Fi, you're sharing a network with dozens of strangers, and a single skilled malicious actor is all that’s necessary for a major data breach to occur. 

The two most common traps are:

• "Man-in-the-Middle" (MiTM) Attacks: This happens when a hacker secretly positions themself between your device and the Wi-Fi router. They can then intercept, read, and even alter your data. Every password you type, every company file you access, and every email you send passes right through their hands. This could result in a major data breach for your business or company.
  ‍
• "Evil Twin" Networks: This happens when a malicious actor sets up a fake Wi-Fi network with a name that looks legitimate, like "Airport_Free_WiFi_" instead of the official "Airport_Free_WiFi." You connect to their network by mistake, and they get direct access to everything on your device. It’s a simple trick that catches thousands of people off guard.
  ‍

2. Physical threats: From theft to tampering

While we often focus on digital threats, the physical security of your devices is just as important. This includes:

• Theft: Leaving your laptop unattended for just a moment is all a thief needs.
  ‍
• Shoulder surfing: A person sitting behind you can easily see your screen and watch you type in passwords or view confidential information.
  ‍
• Juice jacking: A public USB charging port at the airport could be a trap. Malicious actors are known to modify these ports to install malware or spyware onto your device the moment you plug in, stealing your data while your device charges, hence the term"juice jacking."
  ‍

3. Unmanaged devices and endpoint vulnerabilities

An "endpoint" is any device that connects to your network: laptops, phones, tablets. When working remotely, many of these are personal, unmanaged devices. These devices often lack essential security features like firewalls, antivirus software, and timely updates, making them weak links, allowing exploitation. Unlike in an office where the IT department monitors every device, remote setups include personal phones and home smart devices on the same network. 

For instance, an employee connects their work laptop to their home Wi-Fi. Their child's tablet, on the same network, downloads a game with malware. The malware scans the network, finds the work laptop, and exploits a vulnerability to gain access to the company's network.
‍

4. The dangers of  unapproved software "Shadow IT"

Shadow IT refers to using software, apps, or cloud services without your company's approval. To get a task done faster, you might use a personal Google Drive or a free file-sharing service to handle work documents. These services may not be secure, creating a "shadow" system where sensitive data is stored without security consideration.

For example, a marketing team uses an unsecured web service to share large campaign videos with a contractor. That service suffers a data breach, and the unreleased marketing materials are leaked online. 

‍

5. Blurred lines between personal and corporate data

The convenience of remote work often leads to poor data hygiene, mixing personal and professional information.

• The risk: When employees use one device for both work and personal affairs, corporate data inevitably ends up in personal spaces. A sensitive work document might be saved to a personal cloud account that is synced across multiple family devices, or a confidential client email might be forwarded to a personal email address for easier printing. This removes the data from the company's secure environment and places it into an uncontrolled, personal one, where it is more vulnerable to breaches.
  ‍
• Real-world scenario: An employee saves a spreadsheet containing client contact information to their personal laptop to finish some work over the weekend. That laptop is later used by a family member who unknowingly clicks on a phishing link, leading to the spreadsheet being stolen by attackers who then sell the client list on the dark web. This attack is usually effective because personal laptops typically lack robust endpoint protection, such as anti-malware software.

Tips for secure remote work

Now that you understand the threats, here are the practical steps to protect yourself. Turn these into habits, and you can work safely from anywhere.
‍

Essential habits & tools

1. Use a VPN religiously
   ‍A Virtual Private Network (VPN) is non-negotiable on public Wi-Fi. It encrypts your internet connection, hiding your activity from hackers. Turn it on before you do anything else.
   ‍
2. Prioritise your phone's hotspot
   ‍Your phone's mobile hotspot is almost always more secure than public Wi-Fi. It’s your personal, password-protected network.
   ‍
3. Verify public Wi-Fi networks
   ‍If you must use public Wi-Fi, ask an employee for the exact official network name to avoid connecting to an "Evil Twin" trap.
   ‍
4. Enable Two-Factor Authentication (2FA): This is your best defence against password theft. It requires a second verification code, adding an extra layer of security to your work.
   ‍
5. Keep your software updated: Software updates contain critical security patches from app developers. Ignoring them leaves your device exposed to known vulnerabilities that are easy to exploit.

Good digital hygiene

1. Use strong, unique passwords
   ‍Don't reuse passwords. Use a password manager to create and store long, complex passwords for every account.
   ‍
2. Stay alert for phishing scams
   ‍Be extra suspicious of urgent emails or messages asking you to click a link or provide personal information. When in doubt, verify the request through a separate, official channel.
   ‍
3. Back up everything, always: Hardware can fail, devices can be stolen, and ransomware can lock your files. A recent backup is your only true safety net. Follow the 3-2-1 Rule: Keep three copies of your data, on two different types of media (e.g., cloud and an external hard drive), with one copy stored off-site (the cloud copy covers this). 

Physical & device security

1. Secure your physical space
   ‍Never leave your devices unattended. Use a privacy screen filter to stop people next to you from "shoulder surfing" and seeing your screen.
   ‍
2. Always use your charger
   ‍Avoid public USB ports to prevent "juice jacking." Always use your own charger head and plug it directly into a wall socket.
   ‍
3. Separate your work and personal life (On your devices)
   ‍Using the same device for work and downloading personal apps, games, or files from the internet is risky. A virus from a questionable movie download can easily spread to your work files.

• Best practice: Use a laptop dedicated solely to work.
• Good alternative: If you have one device, create a separate user profile on your computer just for work. This keeps your work environment clean and isolated.
  ‍

4. Review apps and bluetooth permissions
   ‍Turn off your Bluetooth when not in use. Regularly review which apps have permission to access your phone's camera, microphone, or location, and revoke any that aren't necessary.
   ‍
5. Be mindful of eavesdroppers (Human and digital)
   ‍Security isn't just about hackers; it's also about your physical environment. Be careful about taking sensitive work calls in public spaces. You never know who is sitting at the next table listening to your conversation about company strategy or a client's project. Step outside or find a private corner.

‍

Conclusion

Remote work security is not a one-time setup. It is a mindset built on awareness. This security mindset does not depend on being a tech expert but it is founded on simple, repeatable actions that build a strong defence over time. Protecting yourself does not require complex software or a degree in cybersecurity. It begins with small, consistent habits that become a natural part of your workday.

Ultimately, the best part of remote work is the freedom it gives you. By taking these steps, you’re not just protecting data, you're protecting that freedom.
