1. Apply Encryption to Data

In the digital age, encryption is a critical line of defence for protecting your business's sensitive information. To successfully apply encryption, you must first identify security holes within your system. This proactive approach allows you to reinforce your defences before a breach occurs.

Once you've assessed your vulnerabilities, the next step is to choose the right encryption type and tool. Popular options include Triple Data Encryption Standard (3DES), Advantage Encryption Standard (AES), and Rivet-Shamir-Adlemon (RSA), each with its own strengths and use cases. For instance:

  • 3DES is known for its triple-layered protection, though it's slower and less common in new technologies.
  • AES is the standard choice, offering varying levels of security such as AES-128, AES-192, or AES-256.
  • RSA relies on public keys for encryption and is widely used, but requires a certain level of technical knowledge.
End-to-end encryption (E2EE) ensures that only authorised individuals can access the data, keeping it secure during transmission. By scrambling the data, E2EE makes it unreadable to anyone without the correct decryption key.

Small businesses, in particular, need to prioritise data privacy to avoid costly breaches. Lessons from past incidents highlight the importance of not only implementing robust security technologies but also ensuring regular software updates, employee training, and adherence to privacy regulations.

2. Set Up a Firewall

Once you've selected the appropriate type of firewall for your business, the next crucial step is to ensure it's properly secured. Designate a network administrator or IT security specialist to take charge of managing firewall access. This individual's responsibilities should include configuring the firewall, regularly updating it, and managing user accounts and passwords.

Configuration of the firewall is not a one-time task; it requires ongoing attention. For instance, every six months, revisit the setup to ensure that the firewall is still effectively protecting your data from cyber threats. Additionally, it's vital to test the firewall's configuration to confirm that it's blocking unwanted traffic while allowing legitimate communication.

Regular testing using security assessments, such as vulnerability scans or penetration tests, is essential. If any issues are detected, detailed test results should be available to facilitate a swift and effective reconfiguration.

Lastly, establish an Access Control List (ACL) to define which services are allowed or denied on your network. This list should be meticulously maintained to reflect the changing needs of your business and the evolving landscape of cyber threats.

3. Establish A Virtual Private Network (VPN)

In today's interconnected world, securing your business's data is paramount, especially when employees are working remotely or travelling. Establishing a Virtual Private Network (VPN) is a critical step in ensuring that your data remains encrypted and inaccessible to unauthorised parties. A VPN creates a secure tunnel for data transfers, effectively masking sensitive information such as IP addresses, passwords, and browsing history.

By implementing a VPN, you provide an essential layer of security for remote and travelling workers, safeguarding your business's network data even when using public or home Wi-Fi.

To set up your VPN effectively, follow these steps:

  1. Select a VPN client, server, and router that meet your business needs.
  2. Download and install the VPN software on the necessary devices.
  3. Configure your network to optimise VPN performance and eliminate conflicts with any previous VPN installations.
  4. Create secure login credentials for each employee who will use the VPN.
  5. Choose the right VPN protocol that aligns with your security requirements and operational needs.

Remember, a VPN is only as secure as its weakest link. Regularly update your VPN software and protocols to maintain robust security. If a VPN connection drops, a kill switch should be in place to immediately disconnect devices from the network, preventing potential data leaks.

4. Be Consistent With Network Monitoring

Consistent network monitoring is the difference between being unaware of cyberattacks and seeing potential attacks before they happen. The process empowers security teams to spot abnormalities and vulnerabilities right away, ensuring that your business is not caught off guard. Network monitoring involves checking three key aspects:

  • Configuration: Assigns and verifies network settings, policies, and controls.
  • Performance: Involves troubleshooting and reporting on various network components.
  • Availability: Assesses network uptime and its response to connection and performance demands.
Network and data security are interconnected and work together to protect data transmission and sensitive information from unauthorised access, theft, or loss.

Regular network scans are a critical component of monitoring. These can be broken down into:

  1. Quick scan: covers common error areas and usually takes 10-20 minutes.
  2. Full scan: checks the entire network and can take 30 minutes to hours.
  3. Scheduled scan: scans consistently at scheduled intervals.

Remember, the availability of your network is crucial for maintaining business operations. Therefore, it is essential to have a robust monitoring system in place that can provide real-time alerts and insights into the health of your network.

Conclusion

In conclusion, securing your business in today's digital landscape is not just advisable, it's imperative. The steps outlined in this article provide a robust framework for protecting your enterprise against the ever-evolving threats posed by cybercriminals. From implementing strong encryption and firewalls to educating employees on cybersecurity best practises, each measure plays a critical role in fortifying your network's defences. Remember, the security of your network is the bedrock upon which the trust between your company and your customers is built.
