If you have installed a new domain controller in an environment that uses AD to store BitLocker Recovery keys, you’ll notice that by default the Recovery Key tab is not present.

Display Name Spoofing / Impersonation is a simple but effective way hackers will try and obtain information, divert funds, and defraud you and your staff.
The hackers will look for executives within your company and then create valid email addresses with their display names on common mailing platforms, and then send requests through requesting funds transferred, bank details etc.
In a busy workplace with only a glance at the display name it would be easy to action these requests without further thought.
The problem is this type of spoofing uses valid email addresses from valid domains, but with the same display name as executives, so mechanisms like SPF, DKIM and DMARC won’t pick them up.
However, by implementing a simple mail-flow rule, you can easily add a warning to this type of message which should prompt the end use to proceed with caution.
Here’s how to set it up.
In this post we’ll look at how to enable SharePoint auditing. Recently I’ve been investigating some mysterious folder moves which the end users couldn’t explain, but folders were disappearing and reappearing elsewhere.

My second thought was to check the SharePoint audit logs. Read on to learn how to enable SharePoint Auditing and view the available reports.
By default SharePoint Auditing isn’t enabled in Office 365.
BitLocker Drive Encryption is the technology in Windows 10 which can encrypt your hard disk drive and keep your data safe. It will usually require you to enter a pin/usb key/certificate to allow access to the encrypted hard disk drive.
Your Windows administrators are able to manage many of the settings in Active Directory, which helps in getting consistent settings across all end user computers. If you try and turn on BitLocker and you get the following error read on how to fix it.
“Your Active Directory Domain Services schema isn’t configured to run BitLocker Drive Encryption. Contact your system administrator.”

The Meltdown and Spectre are two new vulnerabilities in Intel, AMD and ARM processors which will effect everyone.
There is a very good technical article that the Sophos team have put together explaining in detail the issue, you can read it here, as well as many other websites which are covering the story so I won’t go into much detail, just type Meltdown/Spectre into your favourite search engine.
Instead below is a list of the major vendors which we and customers use and links to any articles they have regarding Meltdown and Spectre and their products.
