Query: explain T1686.002 Network Device Firewall
Matching passage: T1686.002 Network Device Firewall. Tactics: defense impairment. Description: Adversaries may disable network device-based firewall mechanisms entirely or add, delete, or modify particular rules in order to bypass controls limiting network usage. Adversaries may obtain access to devices such as routers, switches, or other perimeter/network devices and change access control lists (ACLs), security zones, or policy rules to permit otherwise blocked traffic. For example, adversaries may add new network firewall rules to allow access to all internal network subnets without restrictions. Allowing access to internal network subsets may enable unrestricted inbound/outbound connectivity or open paths for command and control and lateral movement. Adversaries may obtain access to network device management interfaces via [Valid Accounts](https://attack.mitre.org/techniques/T1078) or by exploiting vulnerabilities. In some cases, threat actors may target firewalls and other network infrastructure that are exposed to the internet by leveraging weaknesses in public-facing applications ([Exploit Public-Facing Application](https://attack.mitre.org/techniques/T1190)).(Citation: CVE-2024-55591 Detail) Adversaries may also modify host networking configurations that indirectly manipulate system firewalls, such as adjusting interface bandwidth or network connection request thresholds.
Near-miss passage: T1686 Disable or Modify System Firewall. Tactics: defense impairment. Description: Adversaries may disable or modify host-based or network firewalls to impair defensive mechanisms and enable further action. Once an adversary has gathered sufficient privileges, they can tamper with firewall services, policies, or rule sets to remove restrictions on inbound or outbound traffic. For example, this may include turning off firewall profiles, altering existing rules to permit previously blocked ports or protocols, or adding new rules that create covert communication paths (e.g., adding a new firewall rule for a well-known protocol (such as RDP) using a non-traditional and potentially less securitized port.(Citation: change_rdp_port_conti) Adversaries may disable or modify firewalls using different behaviors, depending on the platform. For example, in ESXi, firewall rules may be modified directly via the esxcli (e.g., via esxcli network firewall set) or via the vCenter user interface.(Citation: Broadcom ESXi Firewall)(Citation: Trellix Rnasomhouse 2024)
