Adversaries may perform Network Denial of Service (DoS) attacks to degrade or block the availability of targeted resources to users. Network DoS can be performed by exhausting the network bandwidth services rely on. Example resources include specific websites, email services, DNS, and web-based applications. Adversaries have been observed conducting network DoS attacks for political purposes(Citation: FireEye OpPoisonedHandover February 2016) and to support other malicious activities, including distraction(Citation: FSISAC FraudNetDoS September 2012), hacktivism, and extortion.(Citation: Symantec DDoS October 2014)
A Network DoS will occur when the bandwidth capacity of the network connection to a system is exhausted due to the volume of malicious traffic directed at the resource or the network connections and network devices the resource relies on. For example, an adversary may send 10Gbps of traffic to a server that is hosted by a network with a 1Gbps connection to the internet. This traffic can be generated by a single system or multiple systems spread across the internet, which is commonly referred to as a distributed DoS (DDoS).
To perform Network DoS attacks several aspects apply to multiple methods, including IP address spoofing, and botnets.
Adversaries may use the original IP address of an attacking system, or spoof the source IP address to make the attack traffic more difficult to trace back to the attacking system or to enable reflection. This can increase the difficulty defenders have in defending against the attack by reducing or eliminating the effectiveness of filtering by the source address on network defense devices.
For DoS attacks targeting the hosting system directly, see Endpoint Denial of Service.

| UEM-10 | Software Firewall | mitigates | T1498 | Network Denial of Service |
Comments
This control describes how CSPs and CSCs must install, update, and properly configure endpoint and software-defined firewalls, regularly review and approve firewall rule changes, and monitor traffic for anomalies and malicious code. These mitigative actions help prevent unauthorized access, block threats, and ensure only approved firewall rules are active.

Comments
Adversaries may perform Network Denial of Service (DoS) attacks to degrade or block the availability of targeted resources to users. Network DoS can be performed by exhausting the network bandwidth services rely on. Example resources include DNS, and web-based services and applications that provide resources to the utility services. This control establishes and regularly evaluates processes, procedures, and technical measures to ensure continuous operations of the datacenter, mitigating attacker techniques such as denial‑of‑service and other availability‑impacting attacks that seek to disrupt business and operational continuity.

Comments
Adversaries may perform Network Denial of Service (DoS) attacks to degrade or block the availability of targeted resources to users. Network DoS can be performed by exhausting the network bandwidth services rely on. Example resources include DNS, and web-based services and applications that provide resources to the utility services.
This control requires securing, monitoring, maintaining, and regularly testing utility services (e.g., power, HVAC, communications) to ensure ongoing effectiveness, mitigating attacker techniques such as disruption of infrastructure, exploitation of unmonitored service failures, and availability attacks that can compromise system resilience.
