## Create an Advanced TCP Protection rule

To create a [SYN flood rule](/ddos-protection/advanced-ddos-systems/overview/advanced-tcp-protection/#syn-flood-protection) or an [out-of-state TCP](/ddos-protection/advanced-ddos-systems/overview/advanced-tcp-protection/#out-of-state-tcp-protection) rule:

<Steps>
1. Log in to the [Cloudflare dashboard](https://dash.cloudflare.com) and select your account.
2. Go to **L3/4 DDoS** > **Advanced Protection** > **Advanced TCP Protection**.
3. Depending on the rule you are creating, do one of the following:

- Under **SYN Flood Protection**, select **Create SYN flood rule**.
- Under **Out-of-state TCP Protection**, select **Create out-of-state TCP rule**.

4. In **Mode**, select a [mode](/ddos-protection/advanced-ddos-systems/concepts/#mode) for the rule.
5. Under **Set scope**, select a [scope](/ddos-protection/advanced-ddos-systems/concepts/#scope) for the rule. If you choose to apply the rule to a subset of incoming packets, select a region or a data center.
6. Under **Sensitivity**, define the [burst sensitivity](/ddos-protection/advanced-ddos-systems/concepts/#burst-sensitivity) and [rate sensitivity](/ddos-protection/advanced-ddos-systems/concepts/#rate-sensitivity) of the rule (by default, _Medium_). The sensitivity levels are based on the initially configured thresholds for your specific case.
7. Select **Deploy**.

Cloudflare's network automatically mitigates large <GlossaryTooltip term="distributed denial-of-service (DDoS) attack" link="https://www.cloudflare.com/learning/ddos/what-is-a-ddos-attack/">DDoS attacks</GlossaryTooltip>, but these attacks can still affect your application.

## All customers

All customers should perform the following steps to better secure their application:

<Steps>
1. Make sure all [DDoS managed rulesets](/ddos-protection/managed-rulesets/) are set to default settings (_High_ sensitivity level and mitigation actions) for optimal DDoS activation.
2. Deploy [WAF custom rules](/waf/custom-rules/) and [rate limiting rules](/waf/rate-limiting-rules/) to enforce a combined positive and negative security model. Reduce the traffic allowed to your website based on your known usage.
3. Make sure your origin is not exposed to the public Internet, meaning that access is only possible from [Cloudflare IP addresses](/fundamentals/concepts/cloudflare-ip-addresses/). As an extra security precaution, we recommend contacting your hosting provider and requesting new origin server IPs if they have been targeted directly in the past.
4. If you have [Managed IP Lists](/waf/tools/lists/managed-lists/#managed-ip-lists) or [Bot Management](/bots/plans/bm-subscription/), consider using these in WAF custom rules.
5. Enable [caching](/cache/) as much as possible to reduce the strain on your origin servers, and when using [Workers](/workers/), avoid overwhelming your origin server with more subrequests than necessary.

To help counter attack randomization, Cloudflare recommends to update your cache settings to exclude the query string as a cache key. When the query string is excluded as a cache key, Cloudflare's cache will take in unmitigated attack requests instead of forwarding them to the origin. The cache can be a useful mechanism as part of a multilayered security posture.

The Cloudflare DDoS Botnet Threat Feed is a threat intelligence feed for service providers (SPs) such as hosting providers and Internet service providers (ISPs) that provides information about their own IP addresses that have participated in HTTP DDoS attacks as observed from Cloudflare's global network. The feed aims to help service providers stop the abuse and reduce DDoS attacks originating from within their networks.
