_______ is a type of malware that encrypts the user's files and demands payment in exchange for the decryption key.
- Adware
- Ransomware
- Trojan
- Worm
Ransomware is a type of malware that encrypts the user's files and demands payment in exchange for the decryption key. It is a significant threat to data security and has been responsible for many high-profile cyberattacks.
In public-key cryptography, the decryption key is kept private and is known as the _______ key.
- Cipher
- Private
- Public
- Secret
In public-key cryptography, the decryption key is kept private, known as the "Private Key." This key is kept secret by the owner and is used to decrypt data that has been encrypted with the corresponding public key.
In the context of threat intelligence, what refers to a set of indicators related to a specific cybersecurity threat?
- Threat Assessment
- Threat Intelligence Report
- Threat Landscape
- Threat Signature
A "Threat Signature" is a set of indicators that characterize a specific cybersecurity threat, helping in its identification and mitigation.
A _______ VPN provides a secure connection between multiple networks over the internet.
- Endpoint-to-Endpoint
- PPTP
- SSL
- Site-to-Site
A Site-to-Site VPN connects entire networks securely over the internet. It's commonly used to connect remote offices or cloud services to the main network.
In the context of social engineering, what does "baiting" usually involve?
- Hiding behind a mask
- Impersonating someone
- Offering something enticing to the victim
- Threatening the victim
Baiting in social engineering involves offering something enticing to the victim. This could be in the form of a free download, a prize, or anything that would make the victim want to take an action that benefits the attacker.
Which secure coding principle emphasizes the importance of denying everything by default and only granting permissions intentionally?
- Defense in Depth
- Fail-Safe Defaults
- Principle of Least Privilege
- Security through Obscurity
The Principle of Least Privilege advocates limiting permissions to the minimum necessary, ensuring that by default, access is denied, and permissions are granted intentionally.
An encryption system that uses the same key to encrypt and decrypt information is known as _______ encryption.
- Asymmetric
- Private
- Public
- Symmetric
Symmetric encryption, also known as private-key encryption, uses the same key for both encryption and decryption. This means that the sender and the recipient must both have access to the same secret key. It is typically faster and less computationally intensive compared to asymmetric encryption.
An organization's IT department wants to enforce a policy where all software installations and updates can only be performed by administrators. This is an example of which type of security policy mechanism?
- Administrative Access Control
- Discretionary Access Control (DAC)
- Mandatory Access Control (MAC)
- Role-Based Access Control (RBAC)
This policy is an example of Role-Based Access Control (RBAC). RBAC is a security mechanism that restricts system access to authorized users or processes based on their roles and responsibilities within the organization. It is commonly used to delegate software installations and updates to administrators.
What type of assessment is primarily focused on ensuring that a company is adhering to its stated security policies and controls?
- Compliance Assessment
- Penetration Testing
- Risk Assessment
- Vulnerability Assessment
A 'Compliance Assessment' primarily aims to ensure that a company is adhering to its established security policies and controls. This assessment checks if the organization follows the security standards it has set for itself.
Which phase of incident response involves determining the scope, size, and origin of an incident?
- Containment
- Detection
- Identification
- Recovery
The Identification phase in incident response involves understanding the incident's scope, size, and origin. This is crucial for formulating an effective response strategy.
