Position: Security Administrator
Dear [CEO’s Name],
I am writing to provide a detailed account of the recent security breach that occurred within our organization, the investigative tools employed to ascertain the breach, the steps taken to mitigate its impact, and the measures we plan to implement to prevent similar incidents in the future.
Summary of Breach Investigation: After conducting a thorough review of the logs from our Intrusion Detection System (IDS), remote access systems, and file servers, I can confirm that a security breach occurred within our Virtual Private Network (VPN). It was discovered that an employee misused company resources to steal sensitive data, employing both their personal laptop and the assigned company computer.
Identifying the Breach Source: Through comprehensive analysis of the log data, it was determined that the breach was carried out using two distinct devices: the employee’s personal laptop and the company-assigned computer. To ascertain the identity of the personal laptop, I employed various digital forensic tools to analyze the data trail left by the device during the breach. This process involved examining IP addresses, MAC addresses, authentication logs, and other digital signatures that would uniquely identify the laptop.
Acquiring Identifying Information: Through the deployment of advanced digital forensics tools and techniques, I was able to extract identifying information from the logs, which allowed me to pinpoint the specific personal laptop used by the employee during the breach. This information was crucial in substantiating our findings and building a solid case.
Items Not Useful for Identification: Certain items are not useful for positively identifying the specific computer used by the insider, such as:
Preventive Measures: To prevent such breaches from occurring in the future, we are implementing the following measures:
Disaster Recovery Plan: In the event of a security breach, we have devised a comprehensive disaster recovery plan that outlines clear steps for employees and vendors to follow. This plan includes:

I am confident that by implementing these measures and fostering a culture of cybersecurity awareness, we can significantly reduce the risk of such breaches and ensure the protection of our sensitive data and assets.
Thank you for your attention to this matter. Please feel free to contact me if you require any further information or clarification.
Sincerely, [Your Name] Security Administrator
Review the following scenario:
An aircraft manufacturing company located in California, with contacts in the U.S. government, had a data breach. Data stolen included employee records containing employee names, addresses, social security numbers, and bank account numbers. It also included current aircraft blueprints. It was determined that the breach occurred due to an open remote access computer an employee set up with a simple password, for ease of working from home.
After reviewing the scenario, list the laws that impact this data breach. Describe the steps the company has to take in order to comply with the identified laws. Also, describe the IT controls the company needs to set up for information security in order to prevent a similar breach in the future.
You must cite examples from state breach notification laws and FISMA.
Scenario
The senior network architect at Corporation Techs has informed you that the existing border firewall is old and needs to be replaced. He recommends designing a demilitarized zone (DMZ) to increase network perimeter security. He also wants to increase the security of network authentication, replacing the current username and password approach.
Tasks
