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.

Remote Desktop Protocol (RDP) is a protocol developed by Microsoft, providing the user access to remotely connect with another computer. Microsoft’s remote desktop protocol is one of the best currently available in the market, working efficiently with an effortless graphical user interface (GUI). It can be used between multiple Windows Operating Systems and Devices. This article discussed RDP protocol security and current RDP vulnerabilities.

Domain Member: Digitally Encrypt or Sign Secure Channel Data is a Microsoft security setting, when enabled, ensures that all traffic to/from the secure channel is encrypted. It is a crucial component of Active Directory that's used by domain members and controllers for seamless communication. The secure channel is essentially a communication channel that allows users uninterrupted access to their user accounts in specific domains.

Server compliance is critical to regulatory compliance, ensuring that organizations meet industry-specific standards for protecting sensitive data. Proper server configuration and continuous risk management are essential to avoid fines and maintain operational integrity. Server compliance is the adherence to specific regulations, standards, and best practices designed to safeguard sensitive information, maintain operational efficiency, and mitigate potential risks.

OS hardening refers to the process of enhancing the security of an operating system by implementing various measures and practices to minimize vulnerabilities and strengthen its resistance against potential cyber threats and attacks. This involves configuring the OS settings, applying security patches, disabling unnecessary services, and implementing access controls to create a more robust and secure computing environment.

NTLM has three versions - NTLMv1, NTLMv2 and NTLMv2 Session Security. NTLMv2 is supposed to offer better security than its previous version, and to some extent it does provides better defense against relay and brute force attacks, but does not completely block them. NTLMv2 Session Security is a session security protocol that can be used in conjunction with NTLMv1 or NTLMv2 to provide additional security.
