The best approach for management in developing a test plan is to use processing parameters that are simulated by production entities and customers. This is because using realistic data and scenarios can help to evaluate the functionality, performance, reliability, and security of the new system under actual operating conditions and expectations. Using processing parameters that are randomly selected by a test generator, provided by the vendor of the application, or randomly selected by the user may not be sufficient or representative of the production environment and may not reveal all the potential issues or defects of the new system.

The primary purpose of creating a simulated production environment with multiple vulnerable applications is to attract attackers in order to study their behavior. This is a technique known as honeypotting, which is a form of deception security that lures attackers into a fake system or network that mimics the real one, but is isolated and monitored1. Honeypotting can help security teams to learn about the attackers' methods, tools, motives, and targets, and to collect valuable intelligence that can be used to improve the security posture of the organization1. Honeypotting can also help to divert the attackers' attention from the real assets and to waste their time and resources2.
The other options are not the primary purpose of creating a simulated production environment with multiple vulnerable applications. To collect digital evidence of cyberattacks, security teams would need to use forensic tools and techniques that can preserve and analyze the data from the compromised systems or networks3. To provide training to security managers, security teams would need to use simulation tools and scenarios that can test and enhance their skills and knowledge in responding to cyber incidents4. To test the intrusion detection system (IDS), security teams would need to use penetration testing tools and methods that can evaluate the effectiveness and performance of the IDS in detecting and preventing malicious activities5.

The best way to detect unauthorized copies of licensed software on systems is to conduct periodic software scanning. Software scanning is a process of using specialized tools or programs to scan the systems and identify the software installed, the license status, the usage, and the compliance with the software policies and agreements. Software scanning can help to detect any unauthorized, unlicensed, or illegal copies of software on the systems, as well as any discrepancies or violations of the software licenses. Software scanning can also help to optimize the software inventory, reduce the software costs, and improve the security and performance of the systems12.
Some examples of software scanning tools are:
* Microsoft Software Inventory Analyzer (MSIA): A free tool that scans Windows-based computers and servers and generates reports on the Microsoft products installed, such as operating systems, applications, and updates3.
* Belarc Advisor: A free tool that scans Windows-based computers and generates reports onthe hardware and software installed, including license keys, versions, usage, and security status4.
* Lansweeper: A paid tool that scans Windows, Linux, Mac, and other network devices and generates reports on the hardware and software inventory, license compliance, configuration, and vulnerabilities5.
To conduct periodic software scanning, you need to:
* Choose a suitable software scanning tool that meets your needs and budget.
* Define the scope and frequency of the software scanning, such as which systems to scan, how often to scan, and what information to collect.
* Configure and run the software scanning tool according to the instructions and settings.
* Review and analyze the software scanning reports and identify any unauthorized copies of licensed software on the systems.
* Take appropriate actions to remove or regularize the unauthorized copies of licensed software on the systems.
* Document and report the results and findings of the software scanning.
