Endpoint Denial of Service: Application or System Exploitation

Adversaries may exploit software vulnerabilities that can cause an application or system to crash and deny availability to users. [1] Some systems may automatically restart critical applications and services when crashes occur, but they can likely be re-exploited to cause a persistent DoS condition.

Mitigations

Mitigation Description
Filter Network Traffic

Leverage services provided by Content Delivery Networks (CDN) or providers specializing in DoS mitigations to filter traffic upstream from services.[2] Filter boundary traffic by blocking source addresses sourcing the attack, blocking ports that are being targeted, or blocking protocols being used for transport.

Detection

Attacks targeting web applications may generate logs in the web server, application server, and/or database server that can be used to identify the type of attack. Externally monitor the availability of services that may be targeted by an Endpoint DoS.
