Mark, a network administrator in an organization, was assigned the task of preventing data from falling into the wrong hands. In this process, Mark implemented authentication techniques and performed full memory encryption for the data stored on RAM.
In which of the following states has Steve encrypted the data in the above scenario?
Amber is working as a team lead in an organization. She was instructed to share a policy document with all the employees working from remote locations and collect them after filling. She shared the files from her mobile device to the concerned employees through the public Internet. An unauthorized user accessed the file in transit, modified the file, and forwarded it to the remote employees.
Based on the above scenario, identify the security risk associated with mobile usage policies.
Sharing confidential data on an unsecured network is a security risk associated with mobile usage policies. Mobile devices are often used to access and transmit sensitive information over public or untrusted networks, such as WiFi hotspots, cellular networks, or Bluetooth connections. This exposes the data to interception, modification, or redirection by malicious actors who may exploit mobile security vulnerabilities or use network-based attacks, such as man-in-the-middle, spoofing, or sniffing. To prevent this risk, mobile users should follow best practices such as using encryption, VPN, certificate pinning, and secure protocols to protect the data in transit. They should also avoid sending or receiving sensitive data over unsecured networks or applications, and verify the identity and integrity of the endpoint servers before establishing a connection.

Jessica, a user, wanted to access the Internet from her laptop and therefore sends a connection request to the access point. To identify the wireless client, the access point forwarded that request to a RADIUS server.
The RADIUS server transmitted authentication keys to both the access point and Jessica's laptop. This key helps the access point identify a particular wireless client.
Identify the authentication method demonstrated in the above scenario.
A major fire broke out in the storeroom of CyberSol Inc. It first gutted the equipment in the storeroom and then started spreading to other areas in the company.

Stella, a mobile user, often ignores the messages received from the manufacturer for updates. One day, she found that files in her device are being replaced, she immediately rushed to the nearest service center for inquiry. They tested the device and identified vulnerabilities in it as it ran with an obsolete OS version.
Identify the mobile device security risk raised on Stella's device in the above scenario.
System-based risk is a type of mobile device security risk that arises from the vulnerabilities or flaws in the operating system or firmware of the device. System-based risk can expose the device to malware, spyware, ransomware, or other malicious attacks that can compromise the data, functionality, or privacy of the device. System-based risk can be mitigated by applying regular security updates and patches from the manufacturer or vendor, as well as using antivirus or anti-malware software. In the above scenario, Stella's device faced a system-based risk, as it ran with an obsolete OS version that had vulnerabilities that allowed the files to be replaced. She ignored the messages from the manufacturer for updates, which could have prevented the risk. Reference:
