LAN Manager (LM) authentication level is a security setting that determines how Windows systems authenticate network connections. It is a legacy authentication protocol developed by Microsoft for use in older versions of Windows network operations. There are three main protocols involved in LAN Manager Authentication: The LAN Manager Authentication Level setting allows you to choose which protocols your system will use or accept for authentication.

In the previous article, we covered some fundamental information you should know before installing WSUS in your infrastructure. Just to refresh your memory, WSUS stands for Windows Server Update Service, and it is used for the centralized update and reporting of Microsoft-based products. This includes Windows, Windows Servers, Exchange, SQL, SharePoint, and others.

SDDL, or Security Descriptor Definition Language, defines the string format that the ConvertSecurityDescriptorToStringSecurityDescriptor and ConvertStringSecurityDescriptorToSecurityDescriptor functions use to describe the security settings of an object in Windows as a text string. Think of it like a simple language for defining who can access an object (like a file, folder, or registry key) and what they can do with it.

Like most organizations, your company likely invested in various Microsoft products. The Microsoft ecosystem provides businesses with nearly every kind of technology necessary, from workstation operating systems to Azure to Windows 365 that includes cloud-native versions of their traditional Office tools and the communication platform Teams. However, attackers are just as invested in the Microsoft ecosystem.

The cybersecurity landscape is undergoing a significant shift, moving from security tools monitoring applications running within userspace to advanced, real-time approaches that monitor system activity directly and safely within the kernel by using eBPF. This evolution in kernel introspection is particularly evident in the adoption of projects like Falco, Tetragon, and Tracee in Linux environments.

Windows Task Scheduler, previously known as Scheduled Tasks, is a powerful job scheduler built into Microsoft Windows. Its primary function is to launch computer programs or scripts at specific times or intervals predetermined by the user. Introduced as System Agent in Microsoft Plus! for Windows 95, Task Scheduler Windows has evolved into a core component of the Windows operating system.

To most people, the process of logging into a Microsoft Windows machine is a simple process of entering a username and a password. However, for a cybersecurity professional, the process is a carefully orchestrated mechanism. Unfortunately, throughout the history of the various Windows operating system versions, criminals have also sought ways to disrupt this process in order to breach a network. The primary target of these attacks is the Security Account Manager (SAM).

Windows PowerShell is a powerful scripting language and a command-line executor developed by Microsoft to provide a better interface for system administrators to simplify managing and automating administrative tasks. PowerShell was launched in 2006 and has been a standard feature of the Windows operating system (OS) since Windows 7, enabling system administrators to simplify and automate administrative tasks while following essential security best practices.

While NetBIOS (Network Basic Input/Output System) has been historically used for local network communication, it has several security vulnerabilities and limitations, and its use has diminished over time. Here are some reasons why someone might want to disable NetBIOS: Broadcast Traffic: NetBIOS relies on broadcast traffic for name resolution, which can lead to network congestion and inefficiency, especially in larger networks.

User Account Control (UAC) serves as a security feature in Windows, aiming to safeguard the operating system from unauthorized modifications. Whenever alterations demand administrator-level permissions, UAC prompts the user, allowing them to either authorize or reject the requested change.
