19
Q

OTX

A

Open Threat Exchange (OTX) is a community-driven platform where security professionals share and collaborate on threat intelligence to help detect and defend against cyber threats.

20
Q

CTI

A

cyber threat intelligence (CTI)
The process of investigating, collecting, analyzing, and disseminating information about emerging threats and threat sources.

21
Q

fact

A

Threat data can be packaged as feeds that integrate with a security information and event management (SIEM) platform

22
Q

ISACs

A

Information Sharing and Analysis Centers (ISACs) are organizations that collect, analyze, and share critical information about threats and vulnerabilities within specific industries to enhance cybersecurity and resilience.

23
Q

OSINT

A

Open-source intelligence (OSINT)
OSINT is used to identify vulnerabilities and threat information by gathering data from many sources such as blogs, forums, social media platforms, and even the dark web.
