After reading chapter 1 and looking at the link above, you’re ready to participate in the first discussion.
Letâ€s look at a real-world scenario and how the Department of Homeland Security (DHS) plays into it. In the scenario, the United States will be hit by a large-scale, coordinated cyber attack organized by China.

Whenever such attackâ€s happens it is better to hold emergency meetings with the effected organizations such as electric grid infrastructure , department of defence and information technology and also financial companies. By bringing together it will assit in estabilishments of cyber threats and damages brought by such type of attacks.
In regards to presidential executive order on strengthening the cybersecurity of federa networks (Carafano & Heyman, 2015). The order got palced within the days which means government incident teams are in place. This ensureâ€s that incident reponse team in right place and takes action like how attack heppend and how huge impact is depending on SLA.

The fundamental fascinating point is to hold an emergency meeting with the governing main associations heads and the affected individuals, for instance, the pioneer of the electric system infrastructure, the hindrance office close by the IT and establishment, of all everybody and cash related foundation of the organization. This portion will help establishment of damages and risks accomplished by such an attack.

Segregate the system from suspected frameworks and limit the quick assessment to find the real wellsprings of attack. For this circumstance it is an enormous degree encouraged cyber-attack.
Oust the risks from the structures with the guide of good master authorities and execute the required affirmation measures to hinder it in future.
Hazard monitoring and quick response bunch is strengthening to evade such attacks in future.
Perform the research the more than a few divisions to arrange out the security gauges taken with the guide of them or going to execute.
A countrywide level standard of prosperity need to make obligatory to all the ventures and divisions in the country. Thusly the remote screw ups can be evaded, due to how they are additionally results in security bottlenecks.
