Azure - Network Security Group Remediation
This Playbook is part of the Azure Enrichment and Remediation Pack.#
Supported versions
Supported Cortex XSOAR versions: 6.5.0 and later.
This playbook adds new Azure Network Security Groups (NSG) rules to NSGs attached to a NIC. The new rules will give access only to a private ip address range and block traffic that's exposed to the public internet (using the private IP of the VM as stated in Azure documentation). For example, if RDP is exposed to the public internet, this playbook adds new firewall rules that only allow traffic from a private IP address and blocks the rest of the RDP traffic.
Conditions and limitations:
- Limited to one resource group.
- 200 Azure rules viewed at once to find offending rule.
- 2 priorities lower than the offending rule priority must be available.
- Adds rules to NSGs associated to NICs.
