While the cyber kill chain process and the MITRE ATT&CK framework are both models that aid in cybersecurity operations, they have some key differences in how they are approached.The cyber kill chain is based on a military concept focused on the high-level phases of a cyberattack. The progression through the stages is linear, mapping out traditional intrusions and defensive measures that can be leveraged against them. Cyber kill chain can often be limiting due to modern cyberattacks reluctance to follow a linear path, but rather a less predictable pattern.MITRE ATT&CK follows a matrix of attack tactics and techniques and is less linear. This creates a more flexible approach based on a large knowledge base that allows teams to understand where an attacker is, where they're likely going, and how to stop them in their tracks.The key is to blend both frameworks into your cyber countermeasures. Cyber kill chain is often used to develop defensive strategies, while MITRE ATT&CK is leveraged to stay apprised of the latest tactics and techniques used by bad actors.
