Secure By Design Approach in Network Security

The Secure by Design approach emphasizes that network security and cybersecurity should not be seen as additional measures but should be at the core of the system design from the very beginning.

In the Secure by Design approach, systems are designed with security as their foundation. This way, potential vulnerabilities that may arise in the future are anticipated at the initial stage, aiming to prevent threats.

This approach recommends acting with the mindset that prevention is more effective than cure. By considering potential threats and security vulnerabilities from the very beginning while setting up the system, it allows the construction of a more resilient structure against possible threats.

The approach offers many benefits. For example, it provides a proactive stance by allowing threats to be identified and addressed early on, rather than responding after a vulnerability has already been exposed. Moreover, it helps avoid future threat-related costs and prevents unnecessary expenses by foreseeing future investments.

This approach can be applied both when initially setting up the system or when redesigning it. Given that firewalls are one of the most essential requirements of network and cybersecurity, it is necessary to consider the features of the firewall while designing the network and structure it accordingly.

Dividing Multiple Networks

The first step in network design will be creating secure zones and separating units by configuring VLAN support and interface-specific settings, thereby limiting necessary accesses.

Using IDS/IPS Systems

By setting up rules according to attack surfaces to defend against external or internal attacks, the security of critical resources will be enhanced.

Using Secure Protocols

It is necessary to choose secure protocols such as HTTPS, SSH, or VPN for encrypted communication within or outside the company. Restricting other types of communication and managing these protocols with filtering services is another step that will increase security.

Reducing the Attack Surface

Deactivating unnecessary services and ports or limiting their access will reduce the attack surface.

Access Control

Unauthorized access should be prevented, and role-based access control should be implemented. Access authorization tables should be created. Additionally, multi-factor authentication methods should be used for access, preventing unauthorized access.

Establishing Continuous Monitoring and Tracking Systems

Defining which systems will be monitored and tracked beforehand and setting up the necessary alert mechanisms will ensure awareness of attacks or unwanted activities.

As mentioned in the examples above, Coslat Firewall plays a significant role in ensuring network security by supporting the principles of Secure by Design with its advanced features and flexible configuration options.
