CEH cloud modules explain that side-channel attacks exploit indirect information leakage based on hardware characteristics—such as CPU timing, power usage, cache access patterns, or electromagnetic emissions. In virtualized cloud environments, multiple tenants share the same physical hardware, creating opportunities for attackers to extract sensitive data from neighboring virtual machines. By placing a malicious VM on the same host as the victim, an attacker can measure minute differences in timing during cryptographic operations, allowing them to infer private keys or sensitive computations. This aligns precisely with CEH’s definition of a side-channel attack. Cryptojacking involves unauthorized cryptocurrency mining, CPDoS targets caching layers rather than key extraction, and metadata spoofing manipulates cloud metadata endpoints. Only side-channel analysis matches the described attack behavior.

In CEH v13 Cloud Computing, serverless architectures introduce unique security challenges, particularly around Function-as-a-Service (FaaS) permissions. When a serverless function is compromised through an insecure third-party API, the damage depends largely on what the function is allowed to do.

Implementing function-level permission models and enforcing the principle of least privilege ensures that even if a function is exploited, its ability to execute malicious actions is strictly limited. CEH v13 strongly emphasizes granular IAM controls in serverless environments.

While cloud-native security platforms (Option A) and CASBs (Option C) provide visibility and governance, they do not directly prevent excessive permissions. Regular patching (Option D) is important but does not mitigate permission abuse.

CEH v13 identifies least privilege as the single most critical control in preventing serverless abuse and privilege escalation. Therefore, Option B is the correct answer.

CEH v13 explains that packet fragmentation is a classic and effective IDS evasion technique. By breaking malicious payloads into smaller fragments, attackers attempt to prevent the IDS from reconstructing the full packet stream correctly, thereby avoiding signature detection.

Many IDS systems rely on packet reassembly and pattern matching. Fragmented packets can confuse or overload the reassembly process, especially if the IDS is poorly configured. CEH v13 specifically lists fragmentation, overlapping fragments, and out-of-order packets as evasion techniques used to bypass network defenses.

Option B describes malware propagation, not IDS evasion. Option C is a social engineering attack, unrelated to IDS detection. Option D is a denial-of-service attempt, not a stealth evasion method.

CEH v13 highlights that defending against fragmentation-based evasion requires proper normalization and reassembly configuration in IDS/IPS systems. Therefore, Option A is the correct answer.

CEH v13 defines a white hat hacker as a security professional who performs authorized assessments to identify vulnerabilities and strengthen an organization’s defenses. The defining characteristic of white hat activity is the presence of formal permission—typically through a signed rules-of-engagement, scope of work, and explicit authorization from the organization. CEH emphasizes that white hats adhere to legal boundaries, follow ethical guidelines, and document findings to support remediation. They may use the same tools and methodologies as malicious hackers, but the intent and authorization distinguish them. In contrast, black hats operate without permission and with malicious intent. Grey hats act without authorization but may not have malicious motivations, making them inappropriate in a formal penetration testing engagement. Script kiddies lack professional skill and rely on pre-made tools without understanding the underlying techniques. Therefore, the hacker described is a white hat—an ethical professional performing sanctioned testing.
