Cybersecurity-Audit-Certificate Exam Dumps and Practice Questions

The MOST important thing for an IS auditor to consider in an assessment of the potential risk factors when a cloud service provider has not adequately secured its application programming interface (API) is the impact on theconfidentiality, integrity, and availabilityof the cloud service. An API is a set of rules and protocols that allows communication and interaction between different software components or systems. An API is often used by cloud service providers to enable customers to access and manage their cloud resources and services. However, if an API is not adequately secured, it can expose the cloud service provider and its customers to various threats, such as unauthorized access, data breaches, tampering, denial-of-service attacks, or malicious code injection.

Elliptic curve cryptography (ECC)is a more efficient form of public key cryptography as it demands less computational power and offers more security per bit. ECC is based on the mathematical properties of elliptic curves, which are curves that have a special shape that makes them suitable for cryptography. ECC can achieve the same level of security as other public key algorithms with much smaller key sizes, which reduces storage and bandwidth requirements.

One way to control the integrity of digital assets is through the use of hashing. This is because hashing is a technique that applies a mathematical function to a digital asset, such as a file or a message, and produces a unique and fixed-length value, known as a hash or a digest. Hashing helps to verify the integrity of digital assets, by comparing the hash values before and after transmission or storage, and detecting any changes or modifications to the original asset. The other options are not ways to control the integrity of digital assets, but rather different concepts or techniques that are related to information security, such as policies (A), frameworks (B), or caching C.

The FIRST activity associated with a successful cyber attack is reconnaissance. This is because reconnaissance is a phase of the cyber attack lifecycle that involves gathering information about the target organization or system, such as its network topology, IP addresses, open ports, services, vulnerabilities, etc. Reconnaissance helps to identify potential entry points and weaknesses that can be exploited by the attackers in later phases of the attack. The other options are not the first activity associated with a successful cyber attack, but rather follow after reconnaissance in the cyber attack lifecycle, such as exploitation (A), maintaining a presence C, or creating attack tools (D).

A passive activity that could be used by an attacker during reconnaissance to gather information about an organization is using open source discovery. This is because open source discovery is a technique that involves collecting and analyzing publicly available information about an organization, such as its website, social media, press releases, annual reports, etc. Open source discovery does not require any direct interaction or communication with the target organization or its systems or network, and therefore does not generate any traffic or alerts that could be detected by the organization's security controls. The other options are not passive activities that could be used by an attacker during reconnaissance to gather information about an organization, but rather active activities that involve direct or indirect interaction or communication with the target organization or its systems or network, such as scanning the network perimeter (B), social engineering C, or crafting counterfeit websites (D).
