BCS CISMP-V9 BCS Foundation Certificate in Information Security Management Principles V9.0 Exam Practice Test

Answer : B

The Advanced Encryption Standard (AES) is the current specification for the encryption of electronic data established by the National Institute of Standards and Technology (NIST). AES is a symmetric block cipher that can encrypt (encipher) and decrypt (decipher) information, converting data to an unintelligible form called ciphertext and back to its original form, plaintext. The AES algorithm is capable of using cryptographic keys of 128, 192, and 256 bits to encrypt and decrypt data in blocks of 128 bits.It was selected by NIST as a Federal Information Processing Standard (FIPS) to protect electronic data and is widely recognized and used for secure data encryption1.

Answer : C

A hot site is a type of disaster recovery facility that is fully equipped and ready to take over operation at a moment's notice. It includes HVAC, power, communications infrastructure, computing hardware, and a real-time duplication of the organization's existing ''live'' data. This enables an organization to resume operations quickly after a disaster with minimal downtime. Hot sites are typically maintained at a state of readiness and can become operational almost immediately after an incident occurs. This contrasts with cold sites, which provide space and infrastructure but require installation and configuration of equipment, and warm sites, which are partially equipped with some operational resources.

Answer : A

Arson is an act of intentionally setting fire to property for malicious reasons. It is a criminal act and is not classified as a natural disaster. Natural disasters are events that occur due to natural processes of the Earth, such as tsunamis, lightning strikes, and other weather-related events. An electromagnetic pulse can be a natural event if it is caused by solar flares or a man-made event if it is the result of a nuclear explosion.However, arson is always the result of human activity and is not caused by natural processes1.

Answer : D

Anomaly-based intrusion detection systems (IDS) are particularly effective in detecting zero-day attacks because they do not rely on known signatures, which zero-day attacks would not have. Instead, they monitor network behavior for deviations from a baseline of normal activity.This approach can identify suspicious activities that could indicate a novel or unknown threat, such as a zero-day exploit12345.These systems use various methods, including machine learning and deep learning, to detect patterns that could signify an attack, making them a robust solution against the unpredictable nature of zero-day threats12345.

Answer : A

In the context of cloud delivery models, the term ''trusted'' typically refers to the level of security control and assurance that clients can expect. Among the options provided, thePubliccloud delivery model is generally considered to be the least ''trusted'' in terms of security by clients using the service. This is because public clouds are shared environments where the infrastructure and services are owned and operated by a third-party provider and shared among multiple tenants. The multi-tenant nature of public clouds can introduce risks such as data breaches or other security incidents that might not be as prevalent in more controlled environments.

In contrast,Privateclouds are dedicated to a single organization, providing more control over data, security, and compliance.Hybridclouds combine both public and private elements, offering a balance of control and flexibility.Communityclouds are shared between organizations with common goals and compliance requirements, offering a level of trust tailored to the group's needs.

Therefore, while all cloud models come with their own security considerations and potential risks, the public cloud model is typically the one where clients have to place more trust in the provider's security measures, as they have less control over the environment.

Answer : A

Contracting third parties to meet specific security standards is prudent because vulnerabilities within their networks can be exploited to gain unauthorized access to a client's environment. Third-party vendors often have access to an organization's sensitive data and systems, which can become a potential entry point for cyber attackers. By ensuring that third parties adhere to stringent security standards, an organization can better protect itself against the risk of data breaches and cyber attacks that may originate from less secure third-party networks. This proactive approach to third-party security helps maintain the integrity and confidentiality of the organization's data and systems.

Answer : C

The cryptographic protocol that preceded Transport Layer Security (TLS) is Secure Sockets Layer (SSL). SSL was the standard security protocol designed to provide communications security over a computer network before TLS was introduced. TLS evolved from SSL, with the first version of TLS (1.0) being developed as SSL version 3.1.However, the name was changed to TLS to indicate that it was no longer associated with Netscape, the company that developed SSL123.

SSL was used from 1994 until it was deprecated in 2015 by the Internet Engineering Task Force (IETF) due to security vulnerabilities.Before its deprecation, TLS was already being used as a backup protocol for SSL 3.0 and quickly became the successor to SSL3. This transition highlights the continuous effort to improve cryptographic protocols to ensure secure communications over the internet.
