A method automatically and quickly provides information after a data breach or incident in relation to data has occurred. In particular, a method issues data incident notifications when data items naming specific entities have been accessed by someone without authorization. This enables the entities to obtain information on the data items that they are named in and which have been accessed. Advantageously, the present techniques make use of an index to quickly identify the data items which are subject to an incident (such as a data breach or violation of a security policy), and which name entities. Once these data items have been identified, it is possible to generate a notification list that shows each data item naming an entity. A system administrator or security officer can then decide whether to generate a data incident notification to notify an entity about the impacted data items in which they are named.

A Cybersecurity Automated Threat Intelligence and Attack Mitigation System mitigate the effects of a Mass Data Breach, a Malware Attack, and Distributed Denial of Service (DDoS) attacks on a Monitored System protected by a system administrator (referred to as a “SysAdmin”). A System Analyzer identifies the Monitored Systems' hardware, software, and configuration information (“Elements”). A Search Term Extractor processes RSS Feeds, news articles, and other information relating to past cybersecurity attacks (“Articles”) to identify search for each type of attack and related to vulnerabilities of elements of the Monitored Systems. Each Live Article is compared to predetermined search terms to identify if it implies attacks or vulnerabilities. The criticality is also determined. If the Live Article indicates the vulnerability of elements or a specific attack, a notification is sent to the SysAdmin and the persons responsible for each vulnerable element. The System may implement ‘hardening’ of the Monitored Systems if the severity is high.
