CYBERSECURITY AND COUNTERMEASURES 2

Cybersecurity and countermeasures

The normal procedure that DHS should follow after a cyber attack is to perform an

internal investigation that will determine the impact on critical business operations. This is a

critical step in identifying the attacker, finding out about the security vulnerabilities and

emergency improvements that need to be made on the computer systems (Shackelford, 2014).

Since the coordinated attacks have paralyzed many businesses the DHS needs to remain calm

and call for an emergency meeting. The agencies affected by the tampering campaign will be

notified immediately on the extent of the damage based on the available information that they

have collected. All the government heads in charge of the security should be available including

the affected companies. The heads of the affected agencies like the defense department, electric

grid infrastructure, public and financial institutions, and the IT department will be notified about

the attacks to establish the threats and damages posed by the coordinated cyber attack from

China. The DHS will then give a way forward to the affected agencies on how the damage will

be limited for instance rerouting the network traffic, blocking traffic or isolation of the

compromised networks. The public will then be warned against accessing certain sites that are

deemed malicious to the general public.

The security team at the DHS will keep a written log of the actions taken to respond to

the breach. The records would normally consist of disrupted services, affected systems, amount

and type of damage, data and networks affected (Shackelford, 2014). The agencies need to

corporate with the law enforcers to before notifying the affected clients to avoid compromising

with the investigations. The incident response team from the DHS may be deployed to assess the

situation on the companies that have been attacked (Dawson & Omar, 2015). The whole process

will need to be documented to advise the agencies on what they need to do to handle any future
