FAQs

The checklist covers network segmentation, firewall configuration, intrusion detection and prevention systems (IDS/IPS), secure remote access, wireless network security, network monitoring and logging, vulnerability management, and secure configuration of network devices and servers.

It includes specific items for evaluating cloud network security, such as virtual private cloud configurations, cloud access security brokers (CASBs), secure API management, and integration of cloud resources with on-premises network security controls.

The checklist emphasizes the implementation of network segmentation strategies to isolate critical financial systems, enforce the principle of least privilege, and contain potential breaches. It covers the use of VLANs, firewalls, and software-defined networking (SDN) for effective segmentation.

It includes items for assessing the implementation of advanced threat detection technologies, such as AI-powered security information and event management (SIEM) systems, threat intelligence integration, and the use of deception technologies to detect and respond to sophisticated attacks.

Comprehensive audits should be conducted at least annually, with more frequent assessments of critical network components and high-risk areas. Additionally, audits should be performed after significant changes to the network architecture, the introduction of new financial services platforms, or in response to emerging threat landscapes.
