An important patch for a critical application has just been released, and a systems administrator is identifying all of the systems requiring the patch. Which of the following must be maintained in order to ensure that all systems requiring the patch are updated?
To ensure that all systems requiring the patch are updated, the systems administrator must maintain an accurate asset inventory. This inventory lists all hardware and software assets within the organization, allowing the administrator to identify which systems are affected by the patch and ensuring that none are missed during the update process.
Network enumeration is used to discover devices on a network but doesn't track software that requires patching.
Data certification and procurement process are unrelated to tracking systems for patching purposes.
An organization wants to ensure the integrity of compiled binaries in the production environment. Which of the following security measures would best support this objective?
To ensure the integrity of compiled binaries in the production environment, the best security measure is code signing. Code signing uses digital signatures to verify the authenticity and integrity of the software, ensuring that the code has not been tampered with or altered after it was signed.
Code signing: Involves signing code with a digital signature to verify its authenticity and integrity, ensuring the compiled binaries have not been altered.
Input validation: Ensures that only properly formatted data enters an application but does not verify the integrity of compiled binaries.
SQL injection: A type of attack, not a security measure.
Static analysis: Analyzes code for vulnerabilities and errors but does not ensure the integrity of compiled binaries in production.
A network administrator is working on a project to deploy a load balancer in the company's cloud environment. Which of the following fundamental security requirements does this project fulfill?
Deploying a load balancer in the company's cloud environment primarily fulfills the fundamental security requirement of availability. A load balancer distributes incoming network traffic across multiple servers, ensuring that no single server becomes overwhelmed and that the service remains available even if some servers fail.
Availability: Ensures that services and resources are accessible when needed, which is directly supported by load balancing.
Privacy: Protects personal and sensitive information from unauthorized access but is not directly related to load balancing.
Integrity: Ensures that data is accurate and has not been tampered with, but load balancing is not primarily focused on data integrity.
Confidentiality: Ensures that information is accessible only to authorized individuals, which is not the primary concern of load balancing.
Which of the following penetration testing teams is focused only on trying to compromise an organization using an attacker's tactics?
Red teams are focused only on trying to compromise an organization using an attacker's tactics. They simulate real-world attacks to test the effectiveness of the organization's security defenses and identify vulnerabilities.
Red team: Acts as adversaries to simulate attacks and find security weaknesses.
White team: Oversees and ensures the rules of engagement are followed during the penetration test.
Purple team: Facilitates collaboration between the red team and the blue team to improve security.
Blue team: Defends against attacks and responds to security incidents.
