Which of the following are politically motivated hackers who target specific individuals or organizations to achieve various ideological ends?
Answer(s): B
Hacktivists are politically motivated hackers who target specific individuals or organizations to achieve various ideological ends. They may use various methods such as defacing websites, launching denial-of-service attacks, leaking confidential information, or spreading propaganda to advance their causes or protest against perceived injustices.
What is the PRIMARY purpose of creating a security architecture?
The PRIMARY purpose of creating a security architecture is to create a long-term information security strategy that aligns with the organization's business goals and objectives. A security architecture defines the vision, principles, standards, policies, and guidelines for how security will be implemented and managed across the organization's systems, networks, and data.
Cyber threat intelligence aims to research and analyze trends and technical developments in which of the following areas?
Cyber threat intelligence aims to research and analyze trends and technical developments in the areas of cybercrime, hacktivism, and espionage. These are the main sources of malicious cyber activities that pose risks to organizations and individuals. Cyber threat intelligence helps to understand the motivations, capabilities, tactics, techniques, and procedures of various threat actors and groups.
Which of the following is an objective of public key infrastructure (PKI)?
An objective of public key infrastructure (PKI) is to independently authenticate the validity of the sender's public key. PKI is a system that uses cryptographic keys to secure communications and transactions. PKI involves a trusted third party called a certificate authority (CA) that issues digital certificates that link a public key with an identity. The recipient can use the CA's public key to verify the sender's certificate and public key.
Which of the following is a more efficient form of public key cryptography as it demands less computational power and offers more security per bit?
Answer(s): D
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.
