## 1. Purpose
|
||||
|
||||
This policy governs information security in procurement and development, requirements for network services as well as return and secure deletion. It elaborates the information security policy ({{LINK:L00}}) and serves to meet the requirements of VDA ISA 2027.
|
||||
|
||||
## 2. Scope
|
||||
|
||||
This policy applies within the defined ISMS scope ({{ISMS_SCOPE_DESCRIPTION}}).
|
||||
|
||||
## 3. Requirements and implementation
|
||||
|
||||
> Structure per section: **Requirement** (1:1 from VDA ISA; [MUST]/[SHOULD] and — where the protection need applies — [HIGH]/[VERY HIGH]) and **Implementation at {{ORG_NAME}}** (consolidated, to be adjusted where necessary).
|
||||
