- Unauthorized sensitive data doesn’t leave the network
  - IP, personal info, financial statements
  - Both malicious and unintentional
- Scans outbound emails
  - Pre-built regular expressions and keywords
  - Looks at contents of email
    - Supporting info and proximity
- Scores between and 100
  - Severity level
    - Action

## Setting up an Email Server for Testing

- Microsoft Server
- MailEnable
- AD Users and Computers, DNS, IIS

``` text
PS C:\Users\ Administrator> Import-Module ActiveDirectory
PS c:\Users Administrator> $User = Get-ADUser kinda -Properties proxyaddresses
PS C:\users Administrator> Suser-proxyAddresses-Add("SMTP:kinda@example.com")
PS C:\Users\Administrator» Set-ADUser -instance $user
PS c:\users \Administrator> Import-Module ActiveDirectory
Ps c:\Users\Administrator> $User = Get-ADUser brian -Properties proxyAddresses
PS c:\Users \Administrator» $User.proxyAddresses.Add("SMTP:brian@example.com")
PS c:\Users\Administrator> Set-ADUser -instance $User
PS c:\Users\Administrator>
```

## Configuring an Email Client

Setting up mail client is self-explanatory

Make sure that DNS is flushed before your testing you start

``` text
esa.example.com> dnsflush

Are you sure you want to clear out the DNS cache? [N]> Y
```
