A _______ is a list maintained by a Certificate Authority that contains all the certificates it has revoked.
- CA (Certificate Authority)
- CRL (Certificate Revocation List)
- CSR (Certificate Signing Request)
- PKI (Public Key Infrastructure)
A CRL (Certificate Revocation List) is a crucial component of a Public Key Infrastructure (PKI). It is a list maintained by a Certificate Authority (CA) and contains all the certificates it has revoked before their expiration dates. This helps ensure the security of digital certificates and public keys.
What is the primary purpose of a strong password policy in user authentication?
- Enhancing user creativity
- Improving user experience
- Increasing security
- Reducing login times
The primary purpose of a strong password policy in user authentication is to increase security. A strong password policy enforces the use of complex passwords, making it more difficult for unauthorized users to gain access to accounts through brute force or dictionary attacks.
When a policy violation occurs, the CSP can be configured to send a report to a specified URI using the _______ directive.
- content-uri
- policy-uri
- report-uri
- security-uri
The correct directive for configuring CSP to send a report to a specified URI is report-uri. This directive is essential for monitoring and resolving policy violations by receiving reports on security incidents.
A financial institution enforces a policy where users must change their passwords every 45 days, and the new password cannot be any of the last five passwords used. This policy is primarily designed to mitigate which type of threat?
- Brute Force Attacks
- Credential Theft
- Insider Threats
- Password Guessing Attacks
The password policy is designed to mitigate Password Guessing Attacks, where attackers attempt to guess user passwords to gain unauthorized access.
Which security measure can prevent attackers from capturing session IDs by listening to network traffic between the client and server?
- Cross-Site Request Forgery
- HTTPS Encryption
- Rate Limiting
- Secure Cookies
HTTPS (HyperText Transfer Protocol Secure) encryption is a security measure that encrypts data in transit between the client and server, making it difficult for attackers to capture session IDs by eavesdropping on network traffic. It's a fundamental method for ensuring data privacy and security during transmission.
What is the primary advantage of using a biometric authentication method, such as fingerprint or facial recognition?
- Easy to Implement
- High Efficiency
- Low Cost
- Strong Security
The primary advantage of biometric authentication methods like fingerprint or facial recognition is their strong security. Biometrics provide a high level of security because they are based on unique physical or behavioral characteristics, making it extremely difficult for unauthorized users to gain access. These methods are challenging to fake or replicate, enhancing security.
Which device is typically used to segment a network and control incoming and outgoing network traffic based on security policies?
- Hub
- Modem
- Router
- Switch
A router is used to segment a network and control network traffic based on security policies by directing traffic between different network segments, effectively acting as a gateway for traffic control.
Which stage of security incident response is focused on eradicating the root cause of the incident?
- Analysis
- Containment
- Identification
- Recovery
The 'Analysis' stage focuses on identifying the root cause of the incident by examining how the breach occurred. Once the root cause is known, efforts can be directed toward eradicating it and preventing future occurrences.
In the context of IPsec, what does AH stand for and what is its primary function?
- Access Handler
- Address Header
- Application Host
- Authentication Header
AH stands for Authentication Header in IPsec. Its primary function is to provide data integrity, authentication, and anti-replay protection for the IP packets, ensuring that they have not been tampered with during transit.
In a sandboxing approach for malware detection, suspicious files are executed in what kind of environment?
- A public cloud environment
- A secure and isolated environment
- The system's production environment
- The user's personal device
In a sandboxing approach for malware detection, suspicious files are executed in a secure and isolated environment, separate from the user's system. This isolation prevents malware from affecting the production system and allows security analysts to observe and analyze its behavior.
