What are the benefits of secure network architecture?

Preventing unauthorized access, limiting lateral movement, improved visibility and control.

What is the purpose of authentication in system security?

Verifying the identity of a user, device, or system

What is multi-factor authentication (MFA)?

Requiring users to provide two or more verification factors.

What is one benefit of multi-factor authentication (MFA)?

Improved security by adding an additional layer of verification

What is the principle of least privilege (POLP)?

Granting users the minimum levels of access necessary.

How does role-based access control (RBAC) work?

Access decisions are based on the roles of individual users.

What is the purpose of regular patching for network devices and software?

Enhancing system functionality and addressing vulnerabilities

Why are unpatched systems considered a significant risk?

They can be exploited by cybercriminals to gain unauthorized access.

What is one risk associated with unpatched systems?

Exploitation of known vulnerabilities

What is a recommended strategy for effective patch management? Options: Establishing a regular patching schedule, Applying all patches immediately, Avoiding patch testing, Disregarding patch prioritization

Establishing a regular patching schedule

How can automated patch management tools help in the patching process?

Identifying missing patches and automating their deployment

What is the purpose of encryption in network security?

To protect sensitive information during transmission.

What is the main benefit of using encryption protocols like SSL/TLS?

Ensuring confidentiality, integrity, and authenticity of data

How does encryption provide data integrity during transmission? Options: By allowing the recipient to verify the data's integrity with the correct decryption key, By encrypting the data to prevent interception, By generating digital certificates for authentication, By establishing secure links between servers and browsers

By allowing the recipient to verify the data's integrity with the correct decryption key

What are the primary features of encryption in network security? Options: Confidentiality, data integrity, and authentication, Bandwidth optimization, access control, and intrusion detection, Vulnerability scanning, firewall management, and network monitoring, Data backup, disaster recovery, and incident response

Confidentiality, data integrity, and authentication

What is the purpose of continuous network monitoring?

Identifying potential issues or threats in real time

How can real-time monitoring help organizations meet compliance requirements? Options: By providing evidence of continuous oversight of system activity and security controls, By optimizing network performance, By eliminating security incidents, By reducing response time to incidents

By providing evidence of continuous oversight of system activity and security controls

What role does log analysis play in network security?

Detecting security incidents and investigating their causes

What is the importance of log records for forensic analysis?

They provide crucial data to understand how security incidents occurred.

Why is employee education and awareness important in network security?

Employees can be the weakest link in the security chain.

What topic should be included in employee training to prevent phishing attacks? Options: Identifying and avoiding phishing emails, Optimizing network bandwidth, Enhancing network access controls, Recovering from system errors
