Case Study:
In this scenario, a virus attack named WannaCry which was encountered in May 2017 has the
ability to hack and encrypt hundreds and thousands of systems universally. This malicious
program utilizes asymmetric encryption which makes the user of the system could not
significantly restore the key required to decode the ransomed data. Moreover, Windows 7 was
the main entry of such malwares via susceptible protocols. Once the malware enters the system,
the vulnerability was permitted with the remote code computation in the system when the
attacker sends particularly designed messages to the Microsoft Server Message Block 1.0
(SMBv1) server. In order to avoid complaints and susceptible scenarios, the software is needed
to be upgraded with the recent updates on current security and susceptibility patches. On
considering the user and commercial requirements, the software can process the change to the
closure and at the time course, the changes can be disappeared gradually devoid of traces and
references.
3. Find the integration issues and propose a solution.
