The correct sequence of steps involved in establishing a network connection using the shared key authentication process is 4 -> 1 -> 3 -> 5 -> 2. This is based on the following description of the shared key authentication process from the Network Defense Essentials courseware:

• The station sends an authentication frame to the AP, indicating that it wants to use shared key authentication.
• The AP responds with an authentication frame containing a challenge text, which is a random string of bits.
• The station encrypts the challenge text using its configured WEP key, which is derived from the shared secret key (password) that is also known by the AP. The station sends the encrypted text back to the AP in another authentication frame.
• The AP decrypts the encrypted text using its configured WEP key and compares it with the original challenge text. If they match, the AP sends a positive authentication response to the station. If they do not match, the AP sends a negative authentication response to the station.
• The station connects to the network if the authentication is successful.

Geofencing is a technique that uses the user’s location data to create a virtual boundary around a specific geographic area. Mobile applications can use geofencing to trigger certain actions or notifications when the user enters or exits the defined area. For example, a mobile application can send a push notification to the user when they are near a store or a restaurant. However, geofencing can also be used by marketers to gather sensitive data and know about users’ offline activities from the location data. For instance, a mobile application can track the user’s movements and preferences based on the places they visit and the time they spend there.This can help marketers to target the user with personalized ads and offers, but it can also pose a threat to the user’s privacy and security12.References:Network Defense Essentials - EC-Council Learning,Geofencing: What Is It and How Does It Work?

The type of attack initiated by Jacob in the above scenario is a cross-container attack. A cross-container attack is a type of attack that targets container technology and exploits the shared resources and network connections between containers. A cross-container attack can compromise the security and availability of multiple containers and the underlying host by performing actions such as stealing data, executing commands, consuming resources, or spreading malware. A cross-container attack can be launched by an external attacker who gains access to a container through a network vulnerability, or by a malicious insider who runs a rogue container on the same host or cluster.A cross-container attack can be prevented or mitigated by implementing security best practices for container technology, such as isolating containers, limiting privileges, enforcing policies, scanning images, and monitoring network traffic123.References:

Onsite data backup is the backup mechanism that is performed within the organization using external devices such as hard disks and requires human interaction to perform the backup operations, thus, making it susceptible to theft or natural disasters. Onsite data backup means storing the backup data on a local storage device, such as an external hard drive, a USB flash drive, a CD/DVD, or a tape drive, that is physically located in the same premises as the original data source. Onsite data backup has some advantages, such as fast backup and restore speed, easy access, and low cost. However, it also has some disadvantages, such as requiring manual intervention, occupying physical space, and being vulnerable to damage, loss, or theft. If a disaster, such as a fire, flood, earthquake, or power outage, occurs in the organization, both the original data and the backup data may be destroyed or inaccessible. Therefore, onsite data backup is not a reliable or secure way to protect the data from unforeseen events.References:
