Active Directory Functionality As mentioned before, there are five Flexible Single Master Operation (FSMO) roles. These roles can be defined as follows:

Understanding Traditional Glucose Values While fasting levels are important to monitor and keep within range, postprandial (after eating) glucose levels are better correlated with overall health. Recent studies have shown that when postprandial glucose levels consistently stay above 140 mg/dL, we start to see an increased risk for many types of disease. ==This measurement is performed approximately 2-3 hours after a meal, and the ideal range is between 70-100 mg/dL==. ==As a general rule, aim to have postprandial values lower than 140 mg/dL, and as close to your pre-meal levels as possible==. ...

Windows Security Security is a critical topic in Windows operating systems. Windows systems have many moving parts that present a vast attack surface. Due to the many built-in applications, features, and layers of settings, Windows systems can be easily misconfigured, thus opening them up to attack even if they are fully patched. It has many built-in features that can be abused and has suffered from a wide variety of critical vulnerabilities, resulting in widely used and very effective remote and local exploits. ...

Desktop Experience vs. Server Core Windows Server Core was first released with Windows Server 2008 as a minimalistic Server environment only containing key Server functionality. As a result, Server Core has lower management requirements, a smaller attack surface, and uses less disk space and memory than its Desktop Experience (GUI) counterpart. ==In Server Core, all configuration and maintenance tasks are performed via the command-line, PowerShell, or remote management with MMC or Remote Server Administration Tools (RSAT==). ...

Windows Subsystem for Linux (WSL) WSL is a feature that allows Linux binaries to be run natively on Windows 10 and Windows Server 2019. It was originally intended for developers who needed to run Bash, Ruby, and native Linux command-line tools such as sed, awk, grep, etc., directly on their Windows workstation. The second version of WSL, released in May 2019, introduced a real Linux kernel utilizing a subset of Hyper-V features. ...

Microsoft Management Console (MMC) The MMC can be used to group snap-ins, or administrative tools, to manage hardware, software, and network components within a Windows host. It has been around since Windows Server 2000 and runs on all Windows versions. We can also use MMC to create custom tools and distribute them to users. MMC works with the concept of snap-ins, allowing administrators to create a customized console with only the administrative tools needed to manage several services. These snap-ins can be added to manage both local and remote systems. ...

Windows Management Instrumentation (WMI) WMI is a subsystem of PowerShell that provides system administrators with ==powerful tools for system monitoring==. The goal of WMI is to consolidate device and application management across corporate networks. WMI is a core part of the Windows operating system and has come pre-installed since Windows 2000. It is made up of the following components: Some of the uses for WMI are: Status information for local/remote systems Configuring security settings on remote machines/applications Setting and changing user and group permissions Setting/modifying system properties Code execution Scheduling processes Setting up logging These tasks can all be performed using a combination of PowerShell and the WMI Command-Line Interface (WMIC). WMI can be run via the Windows command prompt by typing WMIC to open an interactive shell or by running a command directly such as wmic computersystem get name to get the hostname. We can view a listing of WMIC commands and aliases by typing WMIC /?. C:\htb> wmic /? WMIC is deprecated. [global switches] <command> The following global switches are available: /NAMESPACE Path for the namespace the alias operate against. /ROLE Path for the role containing the alias definitions. /NODE Servers the alias will operate against. /IMPLEVEL Client impersonation level. /AUTHLEVEL Client authentication level. /LOCALE Language id the client should use. /PRIVILEGES Enable or disable all privileges. /TRACE Outputs debugging information to stderr. /RECORD Logs all input commands and output. /INTERACTIVE Sets or resets the interactive mode. /FAILFAST Sets or resets the FailFast mode. /USER User to be used during the session. /PASSWORD Password to be used for session login. /OUTPUT Specifies the mode for output redirection. /APPEND Specifies the mode for output redirection. /AGGREGATE Sets or resets aggregate mode. /AUTHORITY Specifies the <authority type> for the connection. /?[:<BRIEF|FULL>] Usage information. For more information on a specific global switch, type: switch-name /? Press any key to continue, or press the ESCAPE key to stop The following command example lists information about the operating system. ...
