==Product Defense in Depth==
Defense in depth is a layered security strategy that employs multiple measures to protect a network. Implementing these strategies helps establish defense system, that are capable to mitigate a wide range of threats.
==Security Capabilities and Defense-in-Depth Strategy==
Application layer:
* '''Authentication and Authorization''' - Ensures only authorized users can access devices administration and programming interfaces.
* '''Access control mechanism''' - prevents unauthorized access to the devices configurations and protects sensitive information.
Network layer:
* '''NAC (Network Access Control)''' - Network level DiD capability that restricts access the networks and sensitive resources.
* '''Network encryption''' - Utilizes encryption mechanisms for wireless communication and IPsec.
* '''Network Firewall''' - Firewalls control ingress and egress network traffic based on predetermined security rules to prevent unauthorized access and traffic.
* '''Network Segmentation''' - Divides the network into smaller, isolated segments. Reduces the attack surface by isolating critical systems.
* '''VPN (Virtual Private Networks)''' - Encrypts data transmitted over the network and ensures secure communication channel for remote access.
* '''Network Failover System''' - Ensures network availability in the event of failure.
* '''Attack prevention''' - Mitigates the risks of most common network layer attacks (e.g.: DoS, SYN Flood).
==Defense-in-Depth recommendations==
The following defense in depth measures are recommended:
* '''Network Segmentation''' - Segment network to isolate different types of traffic and devices.
* '''Secure Access Controls''' - Utilize strong authentication and authorization mechanisms to control access to the network and devices.
* '''Regular Software Updates''' - Keep all software and firmware up to date to protect against known vulnerabilities.
* '''Change Default Configuration''' - Change default usernames, passwords, and settings on the device.
* '''Disable Unused Services''' - Turn off unused services and ports on the device to reduce the attack surface.
* '''Enable Security Features''' - Activate built-in security features, such as SYN Flood protection, HTTP attack prevention, port scan prevention.
* '''Physical Security''' - Restrict physical access to the device and other critical network hardware to authorized personnel only.
