What is Cyber Threat Intelligence?
Cyber threat intelligence (CTI) is the process of collecting, analyzing, and disseminating information about cyber threats in order to prevent or mitigate them. It is a critical component of an organization's cybersecurity strategy, as it allows organizations to proactively identify and defend against potential threats before they can cause damage.
One of the key components of CTI is threat intelligence sharing. This involves sharing information about cyber threats between organizations and government agencies, as well as between security vendors and their customers. By sharing information about threats and vulnerabilities, organizations can better protect themselves against potential attacks. Additionally, threat intelligence sharing allows organizations to stay informed about the latest tactics, techniques, and procedures used by cybercriminals, which can help them develop more effective defenses.
Another important aspect of CTI is threat hunting. This is the process of proactively searching for indicators of compromise (IOCs) on an organization's network. Threat hunting can help organizations identify threats that may have bypassed their existing security controls, as well as uncover previously unknown vulnerabilities. By continuously monitoring their networks and looking for signs of malicious activity, organizations can quickly detect and respond to potential threats.
One of the key challenges of CTI is the sheer volume of data that organizations must sift through in order to identify relevant threats. This is where the use of artificial intelligence (AI) and machine learning (ML) can be particularly valuable. These technologies can be used to analyze large amounts of data and identify patterns that may indicate a potential threat. Additionally, AI and ML can be used to automate many of the manual processes involved in threat hunting, making it more efficient and effective.
CTI is not a one-time event, it's a continuous process. Regularly monitoring and analyzing threat data, as well as updating security controls, is critical to maintaining an effective defense against cyber threats. Organizations should also regularly review and update their incident response plans, so they are prepared to quickly and effectively respond to a cyber incident.
In conclusion, cyber threat intelligence is a critical component of an organization's cybersecurity strategy. By proactively identifying and defending against potential threats, organizations can better protect themselves against cyber attacks. Sharing threat intelligence and leveraging AI and ML can help organizations stay informed about the latest tactics used by cybercriminals and improve their defenses. CTI is not a one-time event, it's a continuous process that requires regular monitoring, analysis, and updating of security controls.

"Prior to VeriClouds, several of my security teams relied on Have I Been Pwned which has all the stuff in public breaches. Using a 3rd party service who are good stewards of more sensitive breach data was important to us to complement our own internal capabilities. That is an area that we did due diligence with VeriClouds."
