WatchGuard Dimension: How to change the Logging Encryption Key

watchguard

It’s good practice to send WatchGuard Firebox traffic logs to a WatchGuard Dimension server so that you have a separate historic log of activity,  as a Firebox won’t retain its logs over a power cycle. The WatchGuard Dimension server can be useful for troubleshooting, but also has a wealth of reports available as well.

To be able to send log traffic to the WatchGuard Dimension server it needs to be encrypted, so you need to supply enter an identical key on the Firebox and in the Dimension server.

If you have multiple Fireboxes you’ll need to know the existing encryption key so you can set it on the additional Fireboxes.

If you don’t know the encryption key, here is how to change it on the WatchGuard Dimension server (don’t forget to change it on existing Fireboxes).

Windows Server 2012 R2: How to create a UPN Suffix

Windows Server 2012 R2

In this post we’ll look at how to create a new User Principal Name (UPN) Suffix. These instructions are also applicable to Server 2008 as well.

The current best practice for new active directory domain naming is a little hazy see my earlier post Active Directory Domain Naming Best Practices.

But for my scenario i decieded to use a sub domain of our registered company domain. This can be confusing for users as their logon name will appear slightly different to their email address.

So to remedy this we can create a new UPN suffix.

In this example I’ve used an ‘ad’ sub domain of my oxfordsbsguy.com domain. So on initial account creation I only have the @ad.oxfordsbsguy.com domain that i can choose.

ADUC - Create New User

To add a new UPN Suffix, open Active Directory Domains and Trusts, and right click the top level on the left hand side Active Directory Domains and Trusts [DC1.ad.oxfordsbsguy.com] and select Properties.

Active Directory Domains and Trusts - Properties

Type in the alternative UPS Suffixes required, in my case I just want my email domain as an additional UPN suffix, and click Add and click OK.

Active Directory Domains and Trusts - UPN Suffixes

Now back in ADUC, if you select the end user and go to the Account tab you can select the new UPN Suffix.

ADUC - User Logon with UPN Suffix

The end user will now have a username the same as their email address which they will be able to use to login with.
