The Path rule is used to specify a path to a folder or application and control access based on that path. By setting a Path rule, an administrator can disallow a system or user from accessing all applications except for those located in a specified folder. This is particularly useful for creating a secure environment where users can only run applications from a trusted location, thereby preventing the execution of unauthorized or potentially harmful programs.

References: This explanation is consistent with the principles of application whitelisting and access control in network security, as outlined in the Certified Network Defender (CND) course materials and objectives, which emphasize the importance of controlling access to system resources to protect against threats.

An Intrusion Detection System (IDS) is designed to monitor network or system activities for malicious actions or policy violations. The correct order of activities that an IDS follows to detect an intrusion starts with Intrusion Monitoring, where it observes the network traffic or system events. Following this, Intrusion Detection takes place, where the IDS analyzes the monitored data to identify potential security breaches. Once a potential intrusion is detected, the Response mechanism is activated to address the intrusion, which may include alerts or automatic countermeasures. Finally, Prevention is applied to improve the system’s defenses against future intrusions based on the detected patterns and responses.

References: This explanation is based on the standard operational procedure of IDS as per the Network Defender (CND) objectives and documents1.

 Port Security is a network security feature on switches that allows the specification of which MAC addresses are permitted on each physical port. When Port Security is enabled, the switch will only permit traffic from the allowed MAC addresses to pass through the specified port, effectively preventing unauthorized devices from accessing the network through that port. This feature is particularly useful for controlling access on a network and ensuring that only known devices can communicate through the switch, thereby increasing the security of the network.

A mantrap is a physical security mechanism designed to control access to a secure area through a small space with two sets of interlocking doors. It is an effective measure to prevent unauthorized access, as it allows only one person to pass through at a time after authentication, thereby stopping any attempt at ‘tailgating’ or ‘piggybacking’ where an unauthorized individual might try to follow an authorized person into a restricted zone.

References: The concept of a mantrap as a physical security control is aligned with the EC-Council’s Certified Network Defender (CND) program, which covers the protect, detect, respond, and predict approach to network security. The CND program emphasizes the importance of various security controls, including physical security measures, to safeguard against unauthorized access and ensure the integrity of the network environment12.

ISO/IEC 27018 is a code of practice for cloud service providers that handle personally identifiable information (PII). It provides a framework for protecting the privacy of PII in the cloud, consistent with the privacy principles in ISO/IEC 29100 for the public cloud computing environment. This standard is particularly relevant for cloud service providers needing to demonstrate they have implemented effective privacy controls to protect their customers’ data. The adoption of ISO/IEC 27018 by a cloud service provider is a strong indication of compliance with privacy laws and regulations, ensuring the protection of personal information in the cloud123.

The Network Interface Card (NIC) operates primarily on the Physical layer of the OSI model. This layer is responsible for the actual transmission and reception of data over a network medium. The NIC provides the physical connection between the computer and the network, converting digital data into electrical, radio, or optical signals for outbound data, and vice versa for inbound data12.

Additionally, the NIC also has functionalities that extend to the Data Link layer, which is responsible for node-to-node data transfer and handling the physical addressing of packets through MAC addresses3.

 According to standard IoT security practices, an IoT Gateway should be connected to a border router. This setup is recommended because a border router acts as a gateway between different networks, managing the traffic between these networks and the internet. It provides an additional layer of security, ensuring that the IoT devices and the internal network are protected from external threats. The border router can implement security measures such as firewalls, intrusion detection systems, and data encryption to safeguard the IoT ecosystem.

References: The standard practice of connecting an IoT Gateway to a border router is supported by security guidelines that emphasize the importance of segregating IoT devices from internal networks to prevent potential cyber threats from spreading across networks123.

In Linux file permissions, the numerical value 755 represents the permissions rwxr-xr-x, where ‘r’ stands for read, ‘w’ for write, and ‘x’ for execute. The first digit ‘7’ corresponds to the file owner’s permissions, allowing read, write, and execute. The second and third digits ‘5’ and ‘5’ correspond to the group and others’ permissions, allowing read and execute. Changing the permission to 744 changes the group and others’ permissions to read only (r–), removing the execute permission.

References: This explanation is based on standard Linux permission conventions and the use of the chmod command to change file permissions1.
