Visited my brother-in-law’s farmhouse. It was built around 1740, long before the internets, or domestic electricity for that matter! The problem: WiFi didn’t extend far from the internet company’s hub in one corner of the house. This made working from home difficult. The fix: I installed a Powerline Wifi extender. Devices in plug sockets create a layer-2 network using the house mains power cabling. You can then install additional wireless access points in other locations around the house for WiFi and ethernet.

CVE-2021-1675 aka PrintNightmare Tl;dr find all servers, with printer published to users in AD, by looking for printerqueue objects. Lots of interest in figuring out which servers offer network printing services due to CVE-2021-1675 aka PrintNightmare. Ideally your org has a well managed print service with DNS aliases to your regional print servers. Or maybe a managed print service over internet? If your print servers are less easy to find try hunting in Active Directory.

Securing Windows PCs starts with managing local administator access. Microsoft Defender for Endpoint logs every login and records if it was a local admin. Use the following KQL query in the Advanced Hunting portal to create a report. Use Active Directory Group Policy to manage the local admins that need to be there for support or management tools. Take care with this policy, one setting removes all admins EXCEPT the ones in the GPO.

Are all your machines encrypted? If a laptop was lost is the data protected or you’ll need to declare. Microsoft Defender for EndPoint (aka ATP) stores Bitlocker status information. Use the following KQL query in the Advanced Hunting portal. The following KQL was inspired by SecGuru_OTX’s twitter post (below) M365 Advanced Hunting: Detect Bitlocker non-compliant Windows 10 devices with "Encrypt all Bitlocker supported drives" setting. pic.twitter.com/YpcNf6NKxe — CISOwithHoodie (@SecGuru_OTX) June 9, 2021 Find more IT Infrastructure tips at blog.

Like many I’ve been working from home for a while. I use a standing desk and a recent and best accessory purchase is, believe it or not, footware. These are fugly but they’re sooo comfortable! I can stand for longer with this soft footware and its well out of sight of conf call camera 😊. Other bits I’m finding useful for a standing desk setup are: Cable management spine from desk to floor

Using AD security groups to delegate access to AzureAD roles is not supported at the moment. This post offers two workarounds. Permissions to manage Azure AD and Office365 are often assigned via Azure AD Roles. If you have strong access management processes and tooling for on prem Active Directory (access request &approval workflow, joiners & leavers, access reviews & reporting, auditing and alerts) you’ll likely want to reuse these to manage access to Azure AD and Office365.

This post has some PowerShell to make Git client work on Windows in corporate environment. Short version Use the Microsoft Credential Manager for Git. Don’t expose passwords in plaintext in Git config or environment variable. The Microsoft Credential Manager will store creds for proxy amd git repo in Windows Credential Manager Git client doesn’t accept domain name in Git config, when you enter creds in Credential Manager change ID to <userID> format Automatically configurge Git client to authenticate with corporate proxy Git client doesn’t support Web Proxy Auto Discovery (WPAD).

Very niche post today. Few will need to delve into Office 365 Compliance Boundaries unless they need to unblock some regulatory compliance requirement. If your in that situation hopefully this will help you. The scenario is this: you have multiple eDiscovery teams in your organisation. Each eDiscovery team should only see content belonging to users in their own sphere of responsibility. Example requirement: eDiscovery team ACME should only be able to see content for company ACME

I wanted to share this idea of using versioned code and unit tests to manage Office365 tenant configuration between environments. So I did a talk about it at the annual WinOps conference in London. Slides so-i-devsecopsed-office-365

A big part of my work lately has been describing, tracking and managing the risk involed with moving data from the traditional datacentre with it’s firewalled perimiter to public cloud. The NIST Cyber Security Framework was useful as a way of grouping and classifying risks. https://www.slideshare.net/AlexMagnay/risk-management-for-public-cloud-projects
