5 page paper-APA formatHomeland Security Use the US-CERT and other similar resources to discuss the vulnerabilities and exploits that might have been used by the attackers. Explore the resources for risk mitigation and provide the risk, response, and risk mitigation steps that should be taken if an entity suffers the same type of attack. US critical infrastructure-power—water, oil and natural gas, military systems, financial systems—have become the target of cyber and physical attacks as more critical infrastructure systems are integrated with the Internet and other digital controls systems. The lesson learned in defending and mitigating cyberattacks is that no entity can prevent or resolve cyberattacks on its own. Collaboration and information sharing is key for success and survival.This is a group exercise, representing collaboration across all sectors, to support and defend US critical infrastructure. In the working world, a team like this would include some agencies, some industrial partners, and some private sector corporations. Each organization has different strengths and skills, different access to information, and different authorities to report to. When the sectors work together and leverage resources and skills, the result is that everyone benefits from the defense and protection of US IT infrastructure. In your teams, you can model the same collaboration, leveraging each other's expertise, sharing each other's knowledge, teaching each other, and providing contributions specific to your role in the scenario.Provide an overview of the life cycle of a cyber threat. Explain the different threat vectors that cyber actors use, and provide a possible list of nation-state actors that have targeted the US financial services industry before. Review this threat response and recovery resource and use what you learned from the resource to provide or propose an analytical method in which you are able to detect the threat, identify the threat, and perform threat response and recovery. Identify the stage of the cyber threat life cycle where you would observe different threat behaviors. Include ways to defend against the threat, and protect against the threat. Intelligence Community Provide intelligence on the nation-state actor, their cyber tools, techniques, and procedures. Leverage available threat reporting such as from FireEye, Mandiant, and other companies and government entities that provide intelligence reports. Also include the social engineering methods used by the nation-state actor and their reasons for attacking US critical infrastructure.
