Cyber Threat Intelligence (CTI) is a term used to address any kind of information that protects your organization’s IT assets from potential security impeachment. CTI can take many forms. It could be internet based IP addresses or geo locations TTP’s (Tools, Tactics and Practices). These work as indicators or early warnings of attacks which can take a toll on an enterprise’s IT infrastructure. There are numerous vendors across the globe whose CTI can be seamlessly made part of security interfaces like GRC tools, SIEM and other correlation engines. That being said, what information can be employed to generate actionable CTI to defend your enterprise security? Let’s look at the same in detail:
Drivers may vary anything from attacks like a ‘zero day’, business related breaking news, or certain announcements that cause vulnerabilities in the enterprise’s activities. Understanding the nature of the drivers can help increase the security vigilance.
This accounts for everything an attacker would need to trigger an attack on your IT infrastructure through intranet perimeter, network, endpoints and just about anything that is exposed to internet.
The script Kidde’s could generate an attack but may not possess the capacity of post-attack activities. Or a professional attacker could have the capabilities of penetrating an attack but its defense mechanism may not be able to stop provide the attacker with intended results. Understanding the capabilities of the attacks and the attackers in absolute length can help defend security to a great extent.
Another element to considered to better equip security concerns is keeping an account of the attacking component’s tools, tactics and procedures that were used in the past attacks conducted by the attacker. This would help generate indicators to better prepare for the forthcoming attacks.
Measurement is important to determine the impact of the attack, mostly in terms of number and types of security events which are generated during the pre-attack condition. The more ways we can interpret different natures and depths of these measurements, the more the security interface can work on the counter-attack measures and recovery processes.
There are many security dimensions that when considered carefully can help avoid, tackle, monitor and help recovery of a security impeachment. While the aforementioned are a hand few, the list can get a lot longer to include threat vectors, compromise parameters, defense mechanism techniques, business impact analytics, attack patterns from the past, zero day detection, security control bypassing, post compromise information, etc.. The more we include these factors, the better IT security vigilance gets.
