Cybersecurity is a continually evolving industry, and businesses must stay on top of threats to safeguard their networks effectively. Cybercriminals use increasingly sophisticated techniques to breach networks, which is why businesses must work proactively to protect themselves. One of the ways to improve network security is by using a cyber kill chain model.
What is a Cyber Kill Chain?
A cyber kill chain is a model used to describe the phases of an advanced cyber-attack. The model outlines the different stages of an attack, starting from initial reconnaissance through to the final objective. Understanding each phase in the cyber kill chain can help organizations build better security defenses against each stage of the attack.
How Can a Cyber Kill Chain Help to Detect Threats?
The cyber kill chain model can improve threat detection by providing a structured approach for analyzing threat activity. Employing this model creates an opportunity to be proactive during an attack. In each phase of the kill chain, you can focus on the behavior, mechanism, and toolkits that attackers utilize. This can help identify specific indicators of attack (IoAs) and initial indicators of compromise (IoCs).
Each phase of the kill chain identifies specific defensive actions that can respond to distinctive attack vectors. The stages of the cyber kill chain include:
Stage 1: Reconnaissance: This is the first stage of a cyber-attack, where attackers research their targets and gather information to probe vulnerabilities.
Stage 2: Weaponization: This phase involves the development of a malware payload that will deliver the attack.
Stage 3: Delivery: This stage begins when the malware is delivered to the target’s system, usually through phishing or other social engineering attacks.
Stage 4: Exploitation: In this stage, the attackers use the malware to compromise the victim’s system. They use various techniques such as memory exploits to execute their payload.
Stage 5: Installation: This stage is where the attackers install backdoors or other tools that enable them to maintain control over the target’s systems
Stage 6: Command and Control: Once they have established control over the target system, the attackers use command and control (C&C) protocol to communicate with the compromised system
Stage 7: Action on Objectives: This is the final stage where attackers can achieve their objectives on the compromised system. It could be data theft, espionage, or ransomware attacks.
Conclusion
With the rise in cybercrime, organizations must take proactive measures to protect their networks. Understanding how cybercriminals carry out their attacks is crucial in developing defensive mechanisms. The cyber kill chain model can help businesses detect threat activity, enabling them to respond to the different stages of an attack, improving network security.
