How Incident Response work!

Let’s assume a fictitious company name called Ford, here Ford is a IT company. Now, The company is suddenly facing some errors in the systems and they call the IR(Incident Response) team to solve it.

First the company sytems was working perfectly. No problem are detceted here.
Suddely the user click a mail which looks professional, once the user click the mail some errors satrts to occur in the users device. And even other system starts to face the same problem because some malwares ca replicate itself and can spread to connected devices.
Now the sensor such as IDS and IPS (Intrusion detection sensor & Intrusion prevention sensor) are not working properly.
After facing some problem the user calls authorities, who can handle the problem.
In the help desk the authorites will ask about the cyberattacks and file it.

After the 7th step the IR team forms three group. That is once group should face the press and the second should face the cyber attack and third group should check other systems.
