Computer systems, especially laptops, are prime targets for theft because of their small size and portability. Almost all businesses depend on computers to some extent, and any interruption caused by loss, theft, or unauthorized access can disrupt operations and expose sensitive data. Even if a stolen or compromised device is replaced, confidential information may already be at risk, leading to potential fraud or data breaches.
To reduce these risks, it’s important for businesses to implement and enforce a comprehensive computer security policy. While physical theft remains a concern, many of today’s biggest risks come from online threats such as connecting to unsecured Wi-Fi, using unknown USB ports, or failing to install software updates. By following a few simple rules, you can strengthen your computer security.
Common laptop and desktop security risks
Unsecured public Wi-Fi
Risks When Using Public Wi-Fi (like in hotels or airports):
- Someone could “listen in” on your internet activity – Hackers might secretly watch the data going between your device and the internet.
- Your online session could be stolen – If you’re logged into a website, someone could pretend to be you and take over your session.
- You could get a virus or malicious software – This can happen if the Wi-Fi network is fake or has been tampered with.
Threats:
- Man-in-the-middle (MITM) attacks – Hackers can intercept data between your laptop and the internet.
- Session hijacking – Attackers can steal session cookies and impersonate users online.
- Malware injection – Through compromised routers or spoofed networks.
Mitigation:
- Use a VPN – It scrambles your internet traffic so others can’t read it.
- Avoid logging into sensitive accounts – Like banking or work systems, unless you really need to.
- Use your phone’s hotspot instead – It’s usually safer than public Wi-Fi.
- Turn off file sharing and auto-connect features – This helps prevent others from accessing your device without permission.
Shoulder surfing
Risk: Working in public places such as airports, cafes, or co-working spaces can increase the risk of shoulder surfing – when someone nearby observes or records sensitive information on your screen.
Threats: Passwords, confidential emails, or documents being seen or recorded.
Mitigation: Using a privacy screen filter, positioning your screen away from others, and being mindful of your surroundings.
Physical theft
Risk: Laptops can be stolen from vehicles, hotels, or shared workspaces, and replacement costs are only part of the problem.
Threats:
- Loss of sensitive or confidential data.
- Unauthorized access if the device isn’t properly secured.
Mitigation:
- Protect your device by using strong passwords and by enabling auto-lock.
- Turning on full-disk encryption so data can’t be accessed if stolen.
- Disable Bluetooth and Wi-Fi when not in use to prevent unauthorized connections.
- Avoid leaving laptops unattended in public or semi-public areas, and always store them in secure, inconspicuous bags when travelling.
USB-based attacks
Risk: Plugging into unknown USB ports or public charging stations can expose your device to malware.
Threats:
- Malware installation.
- Data theft.
Mitigation:
- Avoid plugging into public charging stations (this is called ‘juice jacking’).
- Disable USB ports if not needed.
- Never plug in unrecognized or untrusted devices.
Rogue access points
Risk: Fake Wi-Fi networks can trick you into connecting, then steal your data.
Threats:
- Data interception.
- Credential theft.
Mitigation:
- Always ask staff for the correct network name before connecting.
- Avoid auto-connecting to open networks. This type of attack is especially common in places like coffee shops or airports, where hackers take advantage of high user volume.
Software vulnerabilities
Risk: Outdated software creates an easy entry point for hackers.
Threats:
- Hackers can run harmful code remotely.
- They might gain access to your system.
Mitigation:
- Keep operating systems (OS), antivirus, and applications up to date.
- Enable automatic updates wherever possible.
- Use endpoint protection software provided by your organization to defend against malware and phishing attempts.
Hybrid risks: theft and cybersecurity
In today’s business environment, laptops and desktops are not just vulnerable to physical theft but are also prime targets for cyberattacks. In fact, in Canada in 2023, 16 per cent of businesses experienced a cybersecurity incident, and 13 per cent of those reported ransomware attacks, though most (88 per cent) declined to pay ransom. A stolen or compromised device can provide criminals with direct access to sensitive files, login credentials, or company networks. Even without theft, malware, phishing, and ransomware attacks can compromise desktops and laptops if they are not properly secured.
To reduce hybrid risks, businesses should:
- Use multi-factor authentication on all company accounts.
- Install endpoint protection software and enable automatic updates.
- Encrypt all devices to prevent data exposure if stolen.
- Provide regular cybersecurity awareness training for employees.
- Back up data regularly and store copies securely offsite or in the cloud.
Data backups
Data loss can happen through both theft and system failure, so regular backups are essential. Store copies securely in the cloud or in an offsite location to ensure business continuity in case of an attack or equipment loss, Automated cloud backups are often the most reliable option, as they maintain multiple restore points without manual effort.
Protect your business computers with insurance
Even with strong cybersecurity and physical protection, risks like theft, data breaches, and system compromise can still occur. To learn more about how insurance can provide financial protection and peace of mind, visit our Cyber Risk Insurance page today.
