CND 312-38 Release Date

The Security Reference Monitor (SRM) is the core component in Windows operating systems responsible for controlling access to resources. It enforces security policies and checks whether a user’s request to access a resource is allowed by the system’s security policy. SRM operates in the kernel mode and ensures that access rights and permissions are properly enforced, making it a critical part of the Windows security architecture for resource access control.

References: The role of SRM in Windows security is well-documented and aligns with the information provided in Microsoft’s official documentation and security model, which describes SRM as the component that enforces access controls and security policies within the system12.

The correct commands to update the respective Linux distributions are as follows:

• Red Hat: Uses the yum command or the newer dnf command for package management and updates.
• Fedora: Originally used yum but now has transitioned to dnf as the default package manager.
• Debian: Utilizes the apt-get command for package management tasks, including updates.

The matching from the options provided would be:

• 1-v: Slackware based systems use Autoupdate.
• 2-iii: RPM-based systems, which include Fedora, use Swaret.
• 3-i: Debian based systems use apt-get.
• 4-iv: Red Hat based systems use up2date.

References: This information is based on general knowledge of Linux distribution package managers and their respective update commands. For the most accurate and detailed information, please refer to the official documentation of each Linux distribution and the Certified Network Defender (CND) study materials provided by the EC-Council1.

Application sandboxing is a security technique that allows untrusted or untested programs or code to be executed in a separate, restricted environment known as a sandbox. This environment is isolated from the host system and operating system, ensuring that any potential malicious behavior contained within the code cannot affect the host. It’s a way to test and execute third-party applications without risking the integrity or security of the main system. Sandboxing provides a tightly controlled set of resources for guest programs to run in, such as scratch space on disk and memory, which prevents the programs from affecting other processes and data on the host system.

References: The concept of application sandboxing is covered in the EC-Council’s Certified Network Defender (CND) program, which includes key topics such as application whitelisting, blacklisting, and sandboxing. The hands-on lab exercises in the CND program help demonstrate skills in these areas, including application sandboxing1.

The Payment Card Industry Data Security Standard (PCI DSS) is the relevant standard for any organization that stores, processes, or transmits cardholder data. It outlines a set of requirements designed to ensure that all companies that handle credit card information maintain a secure environment. This includes specific measures for protecting stored cardholder data, encrypting data transmission across public networks, and maintaining a vulnerability management program, among others123.

References: The information provided is based on the PCI DSS Quick Reference Guide and other official documents that detail the requirements for securing cardholder data as per the standards set by the PCI Security Standards Council123.
