Businesses need to continually update security policies as different departments and functions adopt new technology, tools, and ways of dealing with data. Security policies are crucial to have, it needs to update them regularly and all employees need to be trained to comply with each policy update. A best practice for enforcing security policies is zero-trust architecture, which is a strategic approach to cybersecurity that continuously validates at every stage of a digital interaction with data. Examples of this include multi-factor authentication, data protection and computer settings that require users to enter their password whenever they’re away. Make a network segmentation and adjust it based on environments and risk.

Here are some more ways to bridge the cybersecurity gaps: 1. Network Segmentation - To better protect organization resources by isolating them and ensuring access to these resources is available to authorized users. For instance, Internal network and guest network. 2. Implement Access control policies to ensure authorized access and practice least privilege. 3. Implement Endpoint DLP solutions to constantly monitor&protect data regardless of its state. 4. Implement next gen firewalls. 5. Encrypt data and communications using strong Encryption algo such as AES - 256. 6. Implement Zero Trust Model.

To close cybersecurity gaps while designing a new network infrastructure, I would start by conducting a thorough risk assessment to identify potential vulnerabilities. Implementing a layered security approach, such as firewalls, intrusion detection systems (IDS), encryption, and network segmentation, helps mitigate risks. Regular patch management, zero-trust principles, continuous monitoring, and security awareness training for the team would ensure ongoing protection as the infrastructure evolves.
