Access rules - who has access to which systems; - how rights are granted and revoked; - password and account requirements. Example: *the password must be at least 12 characters, MFA is mandatory.* --- ### 2. Use of resources - whether personal devices may be connected; - whether installing software is allowed; - rules for using the internet and email. Example: *using USB drives without approval is prohibited.* --- ### 3. Data protection - what data is considered confidential; - how it should be stored and transmitted; - whether encryption is required. Example: *personal data is transmitted only over secure channels.* --- ### 4. Incident response - what to do in case of a breach or leak; - who to notify; - what steps to take. Example: *in the event of a security incident, an employee must immediately notify the IT department.* --- ### 5. Responsibility - who is responsible for security; - the consequences of violating the rules. Example: *violating the policy can lead to disciplinary action.* --- ## Types of security policy (briefly) - **Organizational** - general rules for the company - **Network** - network protection rules (firewall, VPN, segmentation) - **Access policy** - who can go where - **Password policy** - password requirements - **Incident policy** - how to respond to attacks --- ## Important to understand - A security policy is **not technology**, it is a **document and a set of rules** - Technical tools (firewall, IDS, VPN) **implement** the policy's requirements - The policy is mandatory for all employees --- ## Short answer for the interview Ready-made wording: > *A security policy is a formal document that defines the rules, requirements and responsibilities for ensuring information and network security in an organization.*For the reviewerNote to the moderator (optional)Visible only to the moderator.
