The cyber attack kill chain, also known as CKC or the cyberattack lifecycle, is a security defense model created to identify and thwart sophisticated cyberattacks before they have an impact on an organization. A cyber attack chain model, which is typically seven steps long, deconstructs the various phases of a cyberattack so that security teams can spot, interrupt, or prevent them.
Organizations can better understand relevant threats and enhance incident management and response by utilizing a cyber attack kill chain framework. Cyber kill chains can significantly improve security when implemented properly, but when done incorrectly, they can put organizations at risk. In fact, some flaws in the kill chain raise concerns about its future. Businesses can still use the cyber kill chain methodology for cyberattacks to inform their cybersecurity plans.
Keep reading as we explore everything about Cyber attack kill chain to see why it is a contentious subject in cyber threat management.
What is a attack kill chain in cyber security?
You may have heard the term "kill chain," which refers to military operations in which an enemy attack is identified, dissected into phases, and countermeasures are implemented. This is the exact idea that drove Lockheed Martin to develop the first iteration of the cyber security attack kill chain in 2011.
An organization's defenses against advanced persistent threats (APTs), also known as sophisticated cyberattacks, are strengthened by a cyber attack kill chain. The most common types of threats include the use of:
- Malware
- Ransomware
- Trojan horses
- Phishing
- Other social engineering techniques
Enterprises can be ready and keep up with hackers by using the cyber attack kill chain at every stage of an attack, from conception to execution.
Pros and cons of the cyber attack kill chain
By understanding how cybercrime works EDR, the cyber attack kill chain methodology aims to assist businesses in lowering the risk of attack. The cyber kill chain can be used to evaluate current security measures, spot weaknesses, and address any security risks.
However, technology and cyberattacks have advanced significantly since Lockheed Martin created the cyber attack kill chain in 2011; malicious hackers now utilize a variety of tactics, techniques, and procedures. During the US Senate's investigation into the Target breach in 2013, flaws in the model were demonstrated. In this case, the cyber attack chain model couldn't prevent the attack, demonstrating the requirement for additional measures to safeguard businesses.
Additionally, the model couldn't identify insider threats involving remote access, where a number of threats now fall outside the scope of the cyber kill chain. As opposed to being modified to defend against various attack vectors, the cyber attack kill chain is also entirely focused on network security and preventing malware from being installed.
Assessing employee and customer virtual behavior will help you find threats that the cyber attack chain model failed to identify. Completing a user's behavioral profile and daily tasks will depict abnormalities, including persistently failed login attempts or unstable network traffic.
If you decide to implement an attack kill chain for cyberattacks, you should do so as part of a wider security strategy. A variety of technologies and procedures should be used, such as multi-factor authentication, business antivirus software, malware removal tools, and password management. End-to-end cyberattacks by Advanced Persistent Threats (APTs) require ongoing operational resilience in order to provide effective long-term cybersecurity.
How can the cyber attack kill chain improve security?
Despite the fact that the original seven stages of the cyber attack kill chain have been scrutinized, organizations can still use these principles to better prepare for current and future cyberattacks. A cyber attack chain framework can help a company's cyber security strategy by identifying flaws in the current strategy or confirming what is already working well. It could, for example, incentivize the adoption of services and solutions such as:
- Endpoint protection software
- VPNs
- Employee training
Organizations must implement a plan that involves a layered approach of administrative, technical, and physical security measures as the cyberattack landscape evolves. The cyber attack kill chain methodology can help with this, but the initial model can only go so far.
Attack Kill chain Conclusion
Many people are concerned about the future of the cyber attack kill chain due to the continuous evolution of cyberattacks. An agile cyber kill chain that combines elements of MITRE ATT&CK and extended detection and response (XDR) strategies may be able to detect and neutralize a broader range of threats.
Whatever your opinion is on the cyber attack kill chain framework, addressing existing vulnerabilities and implementing a comprehensive cyber security strategy is crucial for the protection of any business.
