The use of authorized RTU and PLC commands is the security control implemented by Hayes in the above scenario. RTU (Remote Terminal Unit) and PLC (Programmable Logic Controller) are devices that control and monitor industrial processes, such as power generation, water treatment, oil and gas production, etc. RTU and PLC commands are instructions that are sent from a master station to a slave station to perform certain actions or request certain data. The use of authorized RTU and PLC commands is a security control that fortifies the IDMZ (Industrial Demilitarized Zone) against cyber-attacks by ensuring that only valid and authenticated commands are executed by the RTU and PLC devices. Point-to-point communication is a communication method that establishes a direct connection between two endpoints. MAC authentication is an authentication method that verifies the MAC (Media Access Control) address of a device before granting access to a network. Anti-DoS solution is asecurity solution that protects a network from DoS (Denial-of-Service) attacks by filtering or blocking malicious traffic.

 Risk and impact analysis is the threat-modeling step in which Martin evaluated the severity level of the threat in the above scenario. Threat modeling is a process that involves identifying, analyzing, and mitigating threats and risks to a system or network. Threat modeling can be used to improve the security and resilience of a system or network by applying various methods or techniques, such as STRIDE, DREAD, PASTA, etc. Threat modeling consists of various steps or phases that perform different tasks or roles. Risk and impact analysis is a threat-modeling step that involves assessing the likelihood and consequences of threats and risks to a system or network . Risk and impact analysis can be used to evaluate the severity level of threats and risks and prioritize them for mitigation . In the scenario, Martin received breaching alerts for an application. He identified that a vulnerability in the application allowed attackers to enter malicious input. Martin evaluated the threat severity and extent of damage that could be caused by this vulnerability. He then escalated the issue to the security management team to determine appropriate mitigation strategies. This means that he performed risk and impact analysis for this purpose. Identify vulnerabilities is a threat-modeling step that involves finding and documenting the weaknesses or flaws in a system or network that can be exploited by threats or risks . Application overview is a threat-modeling step that involves defining and understanding the scope, architecture, components, and functionality of a system or network .Decompose the application is a threat-modeling step that involves breaking down a system or network into smaller and simpler elements, such as data flows, processes, assets, etc.

Immediate Containment:

Disconnecting the compromised systems from the network is crucial to prevent further exploitation and lateral movement by the attackers. This limits their ability to cause additional harm.
