The right of a company to monitor the activities of their employees on its information systems is typically defined under the "User Access Control" policy. This policy sets out the rules and conditions under which employee activities can be monitored, ensuring that monitoring is conducted legally and ethically while protecting the privacy rights of employees. It often includes provisions for the monitoring of email, internet use, and other digital interactions to safeguard company assets and ensure compliance with corporate policies.References: The establishment and enforcement of user access control policies are fundamental principles in cybersecurity management and are discussed in Network Defender training materials.

The appropriate backup method for a company that wants to ensure data encryption and accessibility from any location at any time is Cloud backup. Cloud backup solutions provide data encryption which secures the data during transmission and storage. Moreover, cloud services are designed to be accessible over the internet, allowing for remote access to the data from any location. This aligns with the company’s requirements for a secure and readily accessible backup method.

References: The EC-Council’s Certified Network Defender (CND) program discusses the importance of data security, including data encryption in transit and at rest, and the use of cloud environments for data backup due to their scalability, accessibility, and security features12.

James should use the Wireshark filter icmp.type==8 or icmp.type==0 to detect a PING sweep attack. This filter will capture both ICMP echo requests and echo replies, which are used in PING sweeps to discover active hosts on a network. When conducting a PING sweep, an attacker sends ICMP echo requests (type 8) to multiple hosts and listens for echo replies (type 0). By monitoring for both types, James can effectively identify a PING sweep attack.

References: The use of this filter for detecting PING sweeps is documented in various network security resources, including the InfosecMatter guide on detecting network attacks with Wireshark1, which specifically lists icmp.type==8 or icmp.type==0 as the filter for ICMP ping sweeps. This approach is consistent with standard practices for network monitoring and intrusion detection.

 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.
