Preview Questions Cybersecurity Specialist (Defense) | Role Specific Skill

Question 1: What is the role of "Firewall Rules Optimization" in enhancing network security for aerospace and defense systems?

Which action should you take?

Choose only one option

Firewall rule optimization is only relevant for reducing costs

Firewall rule optimization is not needed if an IDS is in place

Optimizing firewall rules ensures that the network is protected without unnecessary complexity or performance overhead

Firewall rule optimization is irrelevant for cloud environments

Question 2: 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 3: What is the role of risk analysis in the vulnerability assessment process, and how does it relate to prioritizing vulnerabilities?

Which action should you take?

Choose only one option

It eliminates the need for manual validation of identified vulnerabilities

It ensures that all vulnerabilities are fixed immediately regardless of their impact

It focuses on vulnerabilities related to compliance only

It evaluates the potential business impact of vulnerabilities, allowing for prioritization based on severity and likelihood

Question 4: How does a Cybersecurity Specialist perform a qualitative risk assessment for a defense network?

Which action should you take?

Choose only one option

By assuming all risks are high and prioritizing them without further analysis

By identifying risks based on likelihood and impact, and categorizing them into high, medium, and low

By focusing solely on identifying technical vulnerabilities without evaluating the impact

By evaluating only financial risks and ignoring operational or technical risks

Question 5: How does "Threat Modeling" assist in risk management for aerospace and defense cybersecurity?

Which action should you take?

Choose only one option

It helps identify potential threats, vulnerabilities, and risks, enabling the development of targeted mitigation strategies

It focuses on auditing network logs for identifying suspicious traffic

It eliminates the need for any other risk management activities

It is only useful for identifying internal threats, not external ones

Question 6: What is "X.509" and how is it used in securing communication protocols in defense systems?

Which action should you take?

Choose only one option

X.509 defines the format for public-key certificates, enabling secure communication and identity verification

X.509 is irrelevant in network security protocols

X.509 is used for encrypting private data but does not support identity verification

X.509 only applies to the physical security of communication channels
