Access control is a policy that dictates when to grant certain read/write permissions to users or systems. Access control is a key component of information security, as it ensures that only authorized and authenticated users can access the data and resources they need, and prevents unauthorized access or modification of data and resources1. Access control policies can be based on various factors, such as identity, role, location, time, or context2.

Communications, department-specific, and security policies are not directly related to granting read/write permissions, although they may have some implications for access control. Communications policies are policies that define how information is exchanged and communicated within or outside an organization, such as the use of email, social media, or encryption3. Department-specific policies are policies that apply to specific functions or units within an organization, such as human resources, finance, or marketing. Security policies are policies that establish the overall goals and objectives of information security in an organization, such as the protection of confidentiality, integrity, and availability of data and systems. References: Access Control Policy and Implementation Guides | CSRC; What Is Access Control? | Microsoft Security; Communication Policy - Definition, Examples, Cases, Processes; [Departmental Policies and Procedures Manual Template | Policies and Procedures Manual Template]; [Security Policy - an overview | ScienceDirect Topics].

The open-source licensing model for application software is a type of software license that allows anyone to access, modify, and distribute the source code of the software, subject to certain terms and conditions. The source code is the human-readable version of the software that contains the instructions and logic for how the software works. By making the source code available, open-source software licenses enable collaboration, innovation, and transparency among software developers and users. There are different types of open-source software licenses, such as permissive and copyleft licenses, that vary in the degree of freedom and restriction they impose on the use and modification of the software. However, the common characteristic of all open-source software licenses is that they grant the right to view and use the source code of the software. Therefore, option D is the best description of the open-source licensing model for application software. Option A is incorrect because it describes the opposite of the open-source licensing model. Software that is free to use, but the source code is not available to modify, is called closed-source or proprietary software. Option B is incorrect because it contradicts the open-source licensing model. Modifications to existing software are allowed under open-source software licenses, as long as they comply with the terms and conditions of the license. Option C is incorrect because it does not reflect the open-source licensing model. Code modifications do not need to be submitted for approval under open-source software licenses, although they may need to be shared with the original author or the community, depending on the license. References: CompTIA Cloud Essentials+ CLO-002 Study Guide, Chapter 2: Cloud Concepts, Section 2.4: Cloud Service Models, Page 531 and Understanding Open-Source Software Licenses | DigitalOcean
