Introduction:
A company experienced a severe cybersecurity incident where 70% of its information was impacted by an encryption virus attack. The company needed to investigate the incident immediately, recover the lost data, and develop an action plan to eliminate the chances of such incidents happening again.
Solutions:
Step 1: Investigation
The first step was to analyze the system protection and incident information. It was found that the incident was caused by the absence of email program updates, due to which the hackers were able to operate the mail system and create the virus to infect the operating system of the company.
Step 2: Recovery
The next step was to recover the lost data. The company implemented a data recovery plan to retrieve as much of the impacted information as possible.
Step 3: Action Plan
After the incident was under control, the company developed an action plan to eliminate the chances of such incidents happening again. The plan included:
• Upgrading the data protection subsystem: The company implemented a new data protection system to prevent future encryption virus attacks.
• Organizing update program installation: The company developed a more organized process for installing updates and patches, to ensure that all software and systems are up to date and protected from vulnerabilities.
• Cybersecurity awareness-raising course: The company developed a cybersecurity awareness-raising course for all users. The course helped users understand the importance of following best practices for email safety and how to recognize and report suspicious emails.Results:
As a result of implementing the action plan, the customer received an upgraded data protection subsystem, a new organization of update program installation, and a cybersecurity awareness-raising course for users. Due to the further system monitoring, the number of cyber incidents decreased by 40%.
Conclusion:
This case study highlights the importance of keeping all software and systems up to date and following cybersecurity best practices to prevent cyber incidents. It also emphasizes the importance of having a comprehensive action plan in place to minimize the impact of any potential future incidents.
