ECCouncil Updated 312-50v13 Exam Questions and Answers by alayah

Zero-day exploits are considered the most dangerous mobile attack vector in CEH v13 Mobile Platform Hacking. These exploits abuse previously unknown vulnerabilities, meaning no patches, signatures, or defenses exist at the time of attack.

In healthcare environments, mobile devices access sensitive EHR systems and operate under strict compliance requirements. Zero-day exploits can bypass mobile OS security, sandboxing, and antivirus controls entirely.

App spoofing and Bluejacking are easier to detect and mitigate through user awareness and Bluetooth controls. Side-channel attacks are highly specialized and rare in enterprise mobile environments.

CEH v13 stresses that zero-day attacks pose the greatest risk due to lack of detection mechanisms, making Option A correct.

Side-channel attacks, as explained in CEH v13 OT and SCADA Security, extract sensitive information by observing physical characteristics of a system rather than exploiting software flaws directly. These characteristics may include power consumption, electromagnetic emissions, timing variations, or thermal output.

In SCADA environments, side-channel attacks are especially dangerous because they bypass traditional network defenses. The most reliable way to confirm such an attack is by analyzing hardware-level anomalies—such as unexpected power usage spikes or irregular signal emissions during normal device operations.

Option B directly aligns with CEH v13 guidance.

Options A, C, and D focus on software, cryptography, or network behavior, which are not primary indicators of side-channel exploitation.

Therefore, Option B is correct.

According to CEH v13 Cloud Computing, backup integrity and resilience are critical components of cloud security. The 3-2-1 backup model is a widely recommended best practice to mitigate unauthorized access, data corruption, and ransomware-related incidents.

The 3-2-1 rule dictates that organizations should maintain:

3 copies of critical data

Stored on 2 different media types

With 1 copy stored offsite or offline

This approach ensures that even if one backup is compromised, altered, or deleted—as described in the scenario—clean and trusted versions of the data remain available for restoration. CEH v13 emphasizes that offline or immutable backups significantly reduce the impact of malicious modification.

Option A focuses on physical security, which does not protect cloud backups. Option B addresses availability, not integrity. Option C is relevant to web application security, not backup protection.

CEH v13 explicitly highlights backup segregation and redundancy as key countermeasures against cloud data compromise. Therefore, Option D is the most direct and effective mitigation strategy.

The CEH Cloud Security module highlights identity and access management (IAM) failures as a major source of cloud breaches. Ensuring timely de-provisioning of user accounts when employees leave is a core security control.

Option C is correct.

Options A and B detect issues but don’t prevent access persistence.

Option D is unrelated to access control.

CEH stresses joiner–mover–leaver (JML) processes.
