CSIRT-IE Reports on Internet Accessible Servers & Services - DoS Attacks

Objective

CSIRT-IE primary focus, in regard to the following reports, is to identify Internet accessible servers & services in the State which may be abused in a Denial-of-Service (DoS) attack against a third party.  CSIRT-IE seek to inform responsible network operators and constituents, based upon the IP address of the affected server or service,  by email and to provide advice and recommendations on how to reduce the threat posed by these Internet accessible servers & services.

Internet accessible servers & services may also be used by an attacker for the purpose of performing a reconnaissance, the process of investigating and identifying weak spots in an organisations network and to map its attack surface, prior to an attack.
