6. ERP System:

An Enterprise Resource Planning (ERP) system is a software application that integrates and manages various business functions like accounting, human resources, inventory management, customer relationship management (CRM), and supply chain management.

7. Open-Source vs. Closed-Source Software:

• Open-Source Software: Open-source software has its source code publicly available, allowing anyone to inspect, modify, and distribute the software. This fosters collaboration and innovation among developers. Examples include Linux operating system, and Apache web server.
• Closed-Source Software: Closed-source software has its source code proprietary and confidential. Only the software developer has access to the source code, and users typically need to purchase a license to use the software. Examples include Microsoft Windows, and Adobe Photoshop.

8. Software License:

A software license grants the purchaser the right to use the software under specific terms and conditions. The license may specify how many devices the software can be installed on, whether it can be used for commercial purposes, and the limitations on copying and distributing the software.

2. Security Risks of Open-Source Software Analysis:

The article debunks some myths about open-source software security and highlights real challenges to consider. Here’s my analysis:

• Myths Debunked:
  • Open-source software is inherently less secure than closed-source software. (Both types can have vulnerabilities)
  • Open-source software vendors are not responsible for security. (Many open-source projects have active communities that address security issues)
• Real Challenges:
  • Vulnerability Identification: Open-source software may have more vulnerabilities discovered due to its open nature.
  • Supply Chain Attacks: Malicious actors can target vulnerabilities in dependencies used by open-source software.
