# Whitelist an IP Address in Your EC2 Security Group

### Step 1: Locate Your EC2 Instance

* Log in to the **AWS Management Console**.
* In the search bar at the top, type **EC2** and select it from the list of services.
* In the EC2 Dashboard, click **"Instances (running)"** in the left-hand menu.
* Find and select your EC2 instance by checking the box next to it.

### Step 2: Access the Security Group

* Once you select your instance, the **Details** panel will appear at the bottom of the page.
* Navigate to the **Security** tab. 
* Under **Security Details**, click the linked name of the **Security Group** (shown in blue).

### Step 3: Add the IP Address

* In the Security Group details page, in the **"Inbound rules"** tab, click the **"Edit inbound rules"** button.
* Click **"Add Rule"** and add the following rules in order to provide/gain access to your ui - 

|    Type    | Port |         IP        |
| :--------: | :--: | :---------------: |
|     SSH    |  22  | xx.xxx.xxx.xxx/32 |
| Custom TCP | 4200 | xx.xxx.xxx.xxx/32 |
| Custom TCP | 3000 | xx.xxx.xxx.xxx/32 |
|    HTTPS   |  443 | xx.xxx.xxx.xxx/32 |
|    HTTP    |  80  | xx.xxx.xxx.xxx/32 |

{% hint style="danger" %}
Note: Visit this [site](https://whatismyipaddress.com/) to know your IP address. 
{% endhint %}

### Step 4: Remove the Old/Unwanted IP Address

In the same **Inbound rules** section, identify the IP address you want to remove.

* Click the **Delete** icon next to that entry.
* Review the remaining rules to ensure only the correct IP addresses are listed.
* Click **"Save rules"** to apply the changes. 

The removed IP address will no longer have access, and only specified IP address is now whitelisted and will be able to access your ui.
