Undoubtedly, today’s cyber threats are very fast and sophisticated. Even their detection and prevention is no longer an easy task. To prevent organizations from being a victim of cyber threats and attacks, a proactive cybersecurity approach must be used. That is the reason the Cyber Threat Intelligence (CTI) framework comes into place. CTI has become a critical tool for organizations trying to protect their networks and infrastructure.
Would you sit back in your chair and do nothing while your systems are under attack? You may be, without even realizing it. Businesses are increasingly finding themselves under cyberattacks carried out by hackers or criminals. However, many of them fail to recognize that they have been attacked until it is too late to do anything. That is why timing is the most essential component of cyber security. Fighting attacks proactively instead of reactively can save your systems and networks. This is where real-time threat intelligence comes in handy.
Data is a raw material, which is often unstructured, extracted in massive quantity, and requires processing before calling it an information and actionable intelligence. A good example is the Indicators of Compromise (IoCs). A big list of domain names or IP addresses can be ingested into the SIEM system to identify whether this list contains any malicious IP or not. If any suspicious IP is detected, then we can term this data as an actionable intelligence which has been evaluated from reliable sources, processed and enriched. Now, it can be used to identify trends, attack profile, and possible threats. In this article, we will see how data is gathered, processed, and act as an actionable delivery.
Threat Intelligence Feeds, in fact, are an actionable threat data related to artifacts or indicators collected from any third-party vendors in order to learn from other company’s visibility and access to enhance your own cyber threat response and awareness. The example of these third-party vendors includes Kaspersky Threat Intelligence and Alient Vault OTX. Threat Intelligence Feeds concentrate on a single area of interest and they are delivered online. For instance, these data feeds can be about IP addresses, hashes, or domains.
6. Responding to Threat or Vulnerability
In the previous steps, analysts have gathered enough data to answer their hypothesis. Two types of situations can occur. Either the real threat is found or the vulnerability is detected. In both cases, analysts action is necessary. The analysts must respond immediately when a real threat is identified. However, if there is any vulnerability, they should also resolve this before it becomes a really big nightmare.
