As remote work continues to grow in popularity, it is imperative that both organisations and individuals prioritise securing digital assets and networks. This article explores practical guidelines on securing home networks, using Virtual Private Networks (VPNs), and managing device security to mitigate risks associated with remote working.

Understanding the Cybersecurity Risks of Remote Work

Remote work exposes individuals and businesses to various cybersecurity risks. These risks include unsecured Wi-Fi networks, vulnerability to phishing attacks, and the challenge of securing multiple devices remotely. Additionally, the physical security of devices becomes a concern when employees work from public spaces. Understanding these risks is the first step towards mitigating them.

Other Cybersecurity Risks Associated with Remote Work

Apart from the risks already mentioned, remote work introduces several other cybersecurity challenges:

1. Insecure Personal Devices and Networks: Employees often use personal devices and home networks for work, which may not be as secure as corporate equipment and networks.
2. Increased Use of Cloud Services: Reliance on cloud services for remote work increases the risk of data breaches if these services are not properly secured.
3. Insider Threats: Blurring personal and professional boundaries can increase risks from insider threats, whether unintentional or malicious.
4. Physical Security of Devices: Remote work environments are less controlled, and devices containing sensitive data are more likely to be stolen or lost.
5. Compliance Risks: Remote work can complicate compliance with data protection regulations, as data might be stored or processed differently.

Securing Home Networks

The security of a home network is foundational in the cybersecurity protocol for remote workers. Here are several strategies to enhance the security of your home network:

1. Change Default Router Settings: Many home routers have default usernames and passwords that are easily accessible to hackers. Changing these default settings is a crucial first step in securing your network.
2. Use Strong, Unique Passwords: Use strong, unique passwords for your router and Wi-Fi network. A strong password should include letters, numbers, and special characters.
3. Enable Network Encryption: Encryption technologies like WPA3 should be enabled on your Wi-Fi network to protect the data transmitted.
4. Regularly Update Firmware: Router manufacturers frequently update firmware to fix security vulnerabilities. Keeping your router’s firmware updated can protect you from known exploits.
5. Disable Remote Management: Most routers allow remote management from outside your network. Disabling this feature can prevent external parties from accessing your router’s settings.

Utilising VPNs for Secure Connectivity

A VPN is essential for remote workers as it creates a secure tunnel for data to travel through the internet, thus safeguarding it from interception. Here are key points to consider when using a VPN:

1. Choose a Reputable VPN Provider: Select a VPN provider known for its security and privacy features. Avoid free VPN services as they may not provide adequate security and could even harvest personal data.
2. Always Activate VPN: Ensure that your VPN is activated when accessing corporate resources or handling sensitive data. This is especially important when using public Wi-Fi networks.
3. Use Multi-Factor Authentication (MFA): Enhance VPN security by enabling MFA. This adds an additional layer of security by requiring multiple forms of verification.

Reputable VPN Providers

When choosing a VPN provider for remote work, selecting one known for its robust security features, privacy commitment, and reliable performance is essential. Here are a few reputable VPN providers:

1. NordVPN: Known for its robust encryption protocols and no-logs policy, NordVPN offers additional features such as double VPN, which routes your traffic through two VPN servers.
2. ExpressVPN: This VPN is highly regarded for its fast connection speeds, strong encryption, and servers located in 94 countries, making it a great choice for remote workers needing reliable access from various locations.
3. ProtonVPN: Developed by the team behind ProtonMail, ProtonVPN focuses on security and privacy. It offers features like Secure Core architecture, which routes traffic through multiple servers before leaving the network.
4. CyberGhost: With a user-friendly interface and robust security measures, CyberGhost offers dedicated servers optimised for various needs, including streaming and torrenting.
5. Surfshark: This provider offers unlimited simultaneous connections, allowing you to protect all your devices with a single subscription. It also includes features like CleanWeb, which blocks ads and malware.

Managing Device Security

In a remote work environment, device security becomes crucial since each device potentially serves as an entry point for security threats. Implement the following practices to secure devices:

1. Keep Software Updated: Regular updates to your operating system and applications ensure that security vulnerabilities are patched. Enable automatic updates where possible.
2. Install Antivirus Software: Comprehensive antivirus software can protect against malware, ransomware, and other threats. Scan your devices regularly and update your antivirus software.
3. Use Endpoint Protection Tools: Implementing endpoint protection solutions can help organisations manage and secure devices remotely. These tools can monitor and mitigate threats in real time.
4. Secure Physical Devices: Physical security is often overlooked. Always secure laptops and mobile devices with a password or biometric authentication. Avoid leaving devices unattended in public spaces.
5. Educate on Phishing Scams: Training on recognising phishing attempts is crucial. Employees should be cautious with emails and links from unknown sources. One significant risk is the susceptibility to phishing attacks. Phishing scammers have adapted their methods to exploit remote work environments, often disguising harmful links and attachments as legitimate remote working tools or communications from coworkers.

How Endpoint Protection Solutions Help Manage and Secure Devices Remotely

Endpoint protection solutions play a critical role in securing devices, especially when employees work remotely. These solutions provide multiple functionalities:

1. Threat Detection and Response: Endpoint protection solutions continuously monitor devices for suspicious activities and can automatically respond to threats as they are detected. This is crucial for preventing malware or ransomware from spreading within a network.
2. Policy Enforcement: These tools ensure that all devices comply with corporate security policies. For instance, they can enforce restrictions on installing unauthorised software or accessing certain websites.
3. Patch Management: Keeping software up-to-date is vital for security. Endpoint protection solutions can automate the process of deploying patches across all remote devices, ensuring that vulnerabilities are addressed promptly.
4. Asset Management: They provide visibility into the hardware and software used across the organization. This helps in managing licenses and ensures that all devices are accounted for and secure.
5. Network Access Control: Endpoint protection can restrict access to network resources based on the device’s security posture. This means that if a device is compromised or not compliant with security policies, its access to sensitive resources can be limited or blocked.
