Preview Questions Cybersecurity Specialist (Defense) | Role Specific Skill

Question 1: How does a reverse shell work in ethical hacking, and why is it significant during penetration testing in defense systems?

Which action should you take?

Choose only one option

It directly accesses databases to retrieve sensitive data without detection

It allows the attacker to gain control of a remote system by bypassing firewalls and security measures

It locks the system down by executing a command from an attacker

It prevents attackers from accessing secure systems entirely

Question 2: What role does "Risk Acceptance" play in managing cybersecurity risks in defense networks?

Which action should you take?

Choose only one option

Risk acceptance involves acknowledging risks that cannot be mitigated and continuing operations with a defined risk posture

Risk acceptance is irrelevant if high-risk items are identified

Risk acceptance focuses on reducing the number of security breaches only

Risk acceptance is used to eliminate all potential vulnerabilities in a network

Question 3: What is the role of a risk mitigation strategy in cybersecurity for defense networks?

Which action should you take?

Choose only one option

It accelerates the product development cycle to minimize exposure to risks

It identifies and isolates vulnerable networks to avoid attacks

It involves reducing the likelihood or impact of identified risks through preventive measures or controls

It defines the structure of the organization's IT department

Question 4: In what way do network segmentation and isolation help improve vulnerability assessment outcomes in defense networks?

Which action should you take?

Choose only one option

By allowing unrestricted communication between all systems

By reducing the attack surface and limiting the spread of any potential vulnerabilities, making assessments more manageable

By increasing the number of access points that need to be assessed

By simplifying the network layout and reducing security risks

Question 5: What is the role of the IPsec protocol in securing communication between devices in a defense network?

Which action should you take?

Choose only one option

It verifies the integrity of data without encrypting it

It encrypts and authenticates IP packets to ensure secure communication across an IP network

It speeds up the transmission of data over the network

It secures application-level data in transit

Question 6: Which method is most effective in defending against Man-in-the-Middle (MITM) attacks in a defense network?

Which action should you take?

Choose only one option

Using encrypted communication protocols such as TLS/SSL for data transmission

Relying on basic authentication mechanisms

Implementing open networks without encryption for faster communication

Ignoring network segmentation in favor of a simpler architecture
