What steps can you take to make your core network resilient to attacks?

3 Encrypt your data

The third step to safeguard your core network is to encrypt your data in transit and at rest. Encryption helps you prevent unauthorized interception, modification, or theft of your data. You can use protocols like SSL/TLS, IPSec, or SSH to encrypt your data as it travels across your network devices or the internet. You can also use tools like BitLocker, FileVault, or VeraCrypt to encrypt your data as it is stored on your network devices or servers. Encryption adds an extra layer of security and privacy to your core network.

4 Monitor your network

The fourth step to defend your core network is to monitor it for any abnormal or suspicious activities or events. Monitoring helps you detect and respond to any potential attacks or incidents before they cause serious damage or disruption. You can use tools like network analyzers, intrusion detection systems, or SIEMs to collect, analyze, and alert you of any network traffic or logs that indicate malicious or anomalous behavior. You should also establish a baseline of normal network performance and activity to compare and identify any deviations or anomalies.

5 Update your network

The fifth step to maintain your core network is to update it regularly with the latest patches, firmware, or software. Updating helps you fix any bugs, vulnerabilities, or compatibility issues that could compromise your network security or functionality. You can use tools like patch management systems, configuration management systems, or automation tools to scan, install, and verify the updates on your network devices or servers. You should also backup your network data and configurations before applying any updates to prevent any data loss or corruption.

6 Train your staff

The sixth and final step to enhance your core network is to train your staff on the best practices and procedures for network security and resilience. Training helps you raise awareness, educate, and empower your staff to prevent, detect, and report any network attacks or incidents. You can use tools like e-learning, webinars, or simulations to deliver and assess the training on topics like network policies, password management, phishing awareness, or incident response. Training also helps you foster a culture of security and resilience among your staff.
