The High Security Settings plugin is active by default on all new instances. If it is
not active on your instance, you can request the plugin.

## Vorbereitungen

Role required: None

Before [activating High Security Settings](https://servicenow-prod.fluidtopics.net/x4_sab01YzabJ6GB7Vn~3g "The High Security Settings plugin is active by default on all new instances. If it is not active on your instance, you can request the plugin.") on an existing instance:  
1. Review the following information to understand the new behavior:
   * [Access Control List Rules](https://servicenow-prod.fluidtopics.net/2FgxCh8jBiwu_X5BTzBrnw "Rules for access control lists (ACLs) restrict access to data by requiring users to pass a set of requirements before they can interact with it.")
   * [High Security Settings](https://servicenow-prod.fluidtopics.net/f8gVxeeTKuTUbGIE_Ua8hw "High Security Settings refer to several security options available in your instance.")
   * [Default deny property](https://servicenow-prod.fluidtopics.net/kifgE_R2_Hv9gwQoL~KOfw "The default deny property (glide.sm.default_mode) controls the security manager default behavior when the only matching ACL rules are the wildcard table ACL rules.")
   {#t_ActivateHighSecuritySettings__ul_i2n_hq1_h1b}
2. Enable the plugin on a non-production instance. A recent clone of production is preferable.
3. Test the revised functionality, especially the added ACLs and default-deny functionality. Continue testing until the system performs as expected. If users cannot access expected resources, ensure they have appropriate roles and ACL rules to grant them the access.
4. Create update sets of any needed changes so you can apply them to production.

Hinweis:  
To learn more about this plugin, see [Enable High Security Plugin \[Updated in Security Center 1.3\]](bj_jKmHWfChG2IBu_4WVEA "When you activate the High Security plugin, it creates or updates hundreds of different configurations to control the level of security on your instance. These configurations mitigate many of the top OWASP attacks by enabling strict access control, input validation, and output encoding.") in Instance Security Hardening Settings.
