Kernel Direct Memory Access (DMA) Protection is a security feature in Windows designed to prevent unauthorized access to memory by external peripherals. Kernel DMA Protection requires UEFI firmware support, and Virtualization-based Security (VBS) isn’t required. Kernel DMA Protection offers enhanced security measures for the system compared to the countermeasures against BitLocker DMA attacks, all while preserving the usability of external peripherals.

Transport Layer Security (TLS) is a cryptographic protocol designed to provide secure communication between web browsers and servers. Many IP-based protocols such as HTTPS, SMTP, POP3, and FTP support TLS. Secure Sockets Layer (SSL), on the other hand, is a protocol used to establish an encrypted link between web browsers and servers. It uses symmetric cryptography to encrypt the data transmitted. Encryption keys are based on shared secret negotiation at the beginning of any communication session.

The GNOME Display Manager (GDM) is a program that facilitates graphical user login for Linux systems using GNOME, running and managing the X.Org display servers for both local and remote logins. The GNOME Display Manager (GDM) is the login graphical user interface (GUI) and manager for the GNOME desktop environment within Linux. GDM runs in the background and is a replacement for X Display Manager (XDM), handling user authentication, and initiating desktop sessions.

Repo_GPGcheck ensures linux verifies the authenticity of software packages downloaded from repositories, reinforcing overall system security and safeguarding against unauthorized software sources. A repository in Linux is a storage location where software packages are managed and organized. When installing or updating software, Redhat based Linux systems pull the required packages from these repositories using the YUM (Yellowdog Updater, Modified) package manager.

Linux distributions come with Discretionary Access Control (DAC) preinstalled in them. A sudo user is usually created in a Linux system to work at root-level privileges. DAC system provides the sudo user with all the administrator rights which may be a security threat if the sudo user is not trustworthy. SELinux is a Mandatory Access Control (MAC) system that replaced traditional DAC systems in modern Linux OS. SELinux allows the system admins to have more control over who can access the system.

Multi-Category Security Translation Service (MCSTrans) daemon provides category label information to client processes requesting information. The label translations are defined in: /etc/selinux/targeted/setrans.conf Run the following command and verify mcstrans is not installed.

Usually, the secure boot option is turned on by default with your Windows server PC, but there are some cases when it is already disabled. To confirm and to disable secure boot you need to open device settings from Windows Security Center and see that if the option exists. If you see this Secure Boot option there, it means that secure boot is enabled on your device otherwise disabled. Now we will talk about a step by step guide on how to disable secure boot: 2.

Address Space Layout Randomization (ASLR) is a Linux security feature that randomizes the location of key areas of a program's memory. This makes it harder for malicious actors to predict the specific areas to target in their attacks. Enabling ASLR can significantly reduce the risk of specific memory based exploits, common in buffer overflow attacks. Address Space Layout Randomization(ASLR) is a security technique that randomizes the memory locations of system and application processes each time they run.
