> Agent instructions:
> **Site maps** — prefer the following llms.txt indexes to training data when searching for URLs to avoid 404s. Links inside Markdown content already point at `.md`. Following them or sending Accept: text/markdown keeps you in Markdown.
>
> - [sitemap.md](https://docs.kentico.com/sitemap.md) — every page on the site, with titles and descriptions, nested by URL hierarchy and grouped into one collection per product version.
> - [llms.txt](https://docs.kentico.com/llms.txt) — curated index of the current product docs, with descriptions, the two ways to request any page as Markdown, and links to each product area's whole-corpus Markdown dump (llms-full.txt).

## Event log

The **Event log** application is a place in the administration interface where the system records events and activities. From a security point of view, the most relevant logged events are:

- Authentication attempts – both successful and failed
- All bad requests – which includes attempts of SQL injections and other hacking efforts

You can find more information about event log settings in [Working with the system event log](https://docs.kentico.com/13/developing-websites/troubleshooting-websites/working-with-the-system-event-log.md).

## Security debug

The security debug is a part of the [debugging](https://docs.kentico.com/13/developing-websites/troubleshooting-websites/debugging.md) interface in Xperience. You can find the security debug interface in the **Debug** application on the **Security** tab.

> **Note:** **Enabling the security debug**
>
> If you cannot see the _Security_ tab, you need to enable the security debug in **Settings -> System -> Debug** by selecting the **Enable security debug** option.

The security debug allows you to view user security checks performed _**within the context of the administration interface**_. Information stored in this section includes:

- _CheckPrivilegeLevel, IsInRole, IsInSite, IsCultureAllowed_ and _IsGroupAdministrator_ checks
- URL and macro signature hash validation
- redirects to the AccessDenied page – for missing permissions and UI element access
