312-38 Exam Dumps - Certified Network Defender (CND)

Application sandboxing is a security mechanism that helps prevent the execution of untrusted or untested programs or code from untrusted or unverified third-parties. It does this by running such programs in a restricted environment, known as a sandbox, where they have limited access to files and system resources. This containment ensures that any malicious code or behavior is isolated from the host system, thereby protecting it from potential harm. Sandboxing is a proactive security measure that can significantly reduce the attack surface and mitigate the risk of security breaches.

References: The concept of application sandboxing is covered in the Certified Network Defender (CND) course, which discusses various strategies for protecting networks and systems, including the use of sandboxing to contain and control the execution of potentially harmful code12.

COBIT (Control Objectives for Information and Related Technologies) is a framework designed to help organizations develop, implement, monitor, and improve IT governance and management practices. It is recognized for its comprehensive approach to aligning IT goals with business objectives, ensuring that IT investments support the overall strategic direction of the company. COBIT provides a set of controls over IT and consolidates them into a framework that helps organizations ensure that their IT infrastructure is secure, reliable, and efficient, while also being aligned with their business goals12.

• ISACA’s “Connecting Business and IT Goals Through COBIT 5” article provides insights into how COBIT 5 connects business goals with IT goals using non-technical, business language1.
• The Interface Technical Training blog post on “Aligning IT goals using the COBIT5 Goals Cascade” explains the process of translating stakeholder needs into enterprise goals, IT-related goals, and enabler goals, which is key to supporting alignment between an enterprise’s needs and IT solutions and services2.

 Placing the web server in a separate Demilitarized Zone (DMZ) behind the firewall is a security best practice that allows an organization to isolate its public-facing services from the internal network. This setup ensures that if the web server is compromised, the attacker would not have direct access to the internal network resources. Additionally, the DMZ provides a controlled environment where network traffic to and from the web server can be monitored effectively, facilitating the detection of any future attacks. The firewall serves as a barrier, with specific rules that only allow necessary communication to and from the DMZ, thereby enhancing the overall security posture of the organization.

References: The best practice of using a DMZ is widely recognized in the field of network security and is supported by various security resources, including those provided by the EC-Council’s Certified Network Defender (CND) course and other industry-standard documentation on network security and architecture123.

The correct IEEE standard for wireless networking in a business environment is 802.11. This series of standards defines the protocols for implementing wireless local area network (WLAN) communications in various frequencies, including 2.4, 5, and 60 GHz bands. The 802.11 standards are widely used worldwide and form the basis of wireless network products that are marketed under the Wi-Fi brand. Frank and his colleagues should familiarize themselves with the 802.11 standards to set up a secure wireless network for their firm.

References: The information is based on the IEEE 802.11 series of standards, which are the foundation for Wi-Fi wireless networks. These standards have been developed to ensure interoperability between wireless devices and to provide a secure and reliable means of communication12.

An incremental backup is a type of data backup that copies only the files that have been created or modified since the last backup operation of any type. This method is efficient because it only backs up data that has changed, which can save on storage space and reduce the time needed to complete the backup. In Kelly’s case, since he is backing up only the new or changed files since the last backup, he is using an incremental backup approach.

References: The explanation aligns with the standard backup methodologies where an incremental backup captures only the changes made since the last backup, which can be either a full or another incremental backup1234.
