I can help, but I don’t have enough context yet to determine which peripherals you’re asking about or in what context (e.g., a specific organization’s policy, a particular device, or a regulatory framework). Could you provide a bit more detail on:

• The environment or policy you’re asking about (e.g., military/government IT, corporate IT, educational institution, or personal home setup).
• The exact list of “personally owned peripherals” you want to know about (for example: mice, keyboards, webcams, USB drives, displays, headphones, etc.).
• Any governing documents or standards you want me to reference (if you have a specific policy, handbook, or country/organization in mind).

With that, I can give you a precise, well-sourced answer outlining which peripherals are typically allowed, required approvals, and any restrictions or recommended best practices.
