Given that your current security stack (AntiVirus, Firewall, SIEM, etc.) already comes integrated with its own auto-updated IOC feeds, do you still need an additional IOC threat intel feed?
Cyber Security is an ever-growing challenge where security teams have to deliver within limited resources and time. Thereby, in the current era of information overload, an effective Cyber Security strategy has to address how to steer away from TIN (Threat Intelligence Noise).
Indicators of compromise (IOCs) are the golden factor that enables most of the security technologies to function. Any IP, Domain, URL/Host or file hash that is associated with the malicious activity is introduced as a periodic update to relevant security technologies, enabling detection and blocking of any event that is found attempting to associate with those IOCs.
