With digital development, automation and greater connectedness can also result in risk of cyber attacks. Threat intelligence is the knowledge that allows the users to prevent those attacks. Threat intelligence offers context such as who is attacking you, what their intentions are and help users take logical reasons and decisions about their security.
Why is Threat Intelligence Important?
The cyber security industry faces many challenges that include threats to data, false alarms on data and a shortage of skilled professionals to help protect the data. There are some organizations that try to incorporate threat data feeds in their network but are not sure of what to do with the large amount of data that only adds burden on the analysts. Threat intelligence is actionable. Its timeliness, context and the ability to understand people and make decisions, makes it even more important.
Subcategories of threat intelligence
Threat intelligence is generally broken into three subcategories:
Strategic: These are broader trends that are typically meant for non-technical users.
Tactical: Outlines of the tactics, procedures and techniques are for more technical users.
Operational: Technical details are included about specific attacks and campaigns.
Common Indicators of Compromise
Threat intelligence assists in the process by identifying the common indicators of compromise (IOC) and also recommends necessary steps to prevent the attacks.
IP addresses, domains and URLs: Example of such attack is a malware that targets an internal host that communicates with a known threat actor.
Email addresses, email subjects, attachments and links: Example of such attack is unsuspecting user clicking on a link or attachment that may have malicious command.
Registry keys, filenames and file hashes: Example of such attack can be an external host that has already been flagged for a behavior that is already infected.
