## Security Profile Types

There are two types of security profiles:

| Security Profile               | Description                                                              |
| ------------------------------ | ------------------------------------------------------------------------ |
| **Telephony Security Profile** | Enables customers to define rules and actions for SMS and Things Groups. |
| **IP Security Profile**        | Enables customers to define inbound and outbound rules for IP traffic.   |

The Monogoto customer application uses the default telephony and IP security settings as configured during initial system deployment. Customers can customize the security settings for both Telephony and IP security profiles.

#### **Telephony Security Profile**

Within a **Telephony Security Profile**, you can define **Voice Rules** and **SMS Rules**:

<table><thead><tr><th width="221">Rule</th><th>Description</th></tr></thead><tbody><tr><td>Voice Rules </td><td>Define limitations on numbers or prefixes that a Thing, or a Things group can call to, System users can also create number translations for called destinations</td></tr><tr><td>SMS Rules </td><td>Define limitations on numbers or prefixes that a Thing or Things group can send an SMS to. System users can also define that all SMS traffic going to/from the device will only originate/terminate at the API. This prevents any SMS spoofing or hacking from happening.</td></tr></tbody></table>

## Security Rules

When you create a new Security Profile, you need to create rules assigned to that profile. These rules enable the customer to control the type of actions and the availability of services that can be performed by groups of Things. There are three type of rules that can be assigned to a Security Profile.

<table data-header-hidden><thead><tr><th width="222">Rule Type</th><th>Description</th></tr></thead><tbody><tr><td>Rule Type</td><td>Description</td></tr><tr><td>Inbound</td><td>Define the actions and services available to all inbound traffic.</td></tr><tr><td>Outbound</td><td>Define the actions and services available to all outbound traffic.</td></tr><tr><td>SMS</td><td>Define the actions and services available to SMS traffic.</td></tr></tbody></table>
