Understanding Vulnerabilities and Threats

The video tutorial explains vulnerabilities as weaknesses in systems that can be exploited by attackers. It covers the concept of zero-day attacks, where vulnerabilities are exploited before they are known or patched. The video also discusses threats, both intentional and accidental, and introduces the idea of threat agents. It highlights the importance of managing vulnerabilities using databases like CVE and NVD. The tutorial concludes with access control strategies, emphasizing least privilege and zero trust to protect against insider threats and unauthorized access.

What is a vulnerability in the context of system security?

• A type of malware

• A weakness in a system

• A security policy

• A type of firewall

Which of the following is an example of a vulnerability?

• Data injection flaw

• Strong password policy

• Regular software updates

• Encrypted data storage

What is a zero-day attack?

• An attack that is always detected immediately

• An attack that occurs on the first day of the month

• An attack exploiting a previously unknown vulnerability

• An attack that targets zero systems

Where can details on attack types usually be found?

• In the CVE database

• In the user manual

• In the system logs

• In the firewall settings

What is a threat agent?

• A person or thing exploiting a vulnerability

• A type of antivirus software

• A security protocol

• A network firewall

Which of the following is an example of an accidental threat?

• A DDoS attack

• A hacker breaking into a system

• A fire in the data center

• A phishing attack

What is the concept of least privilege?

• Giving users maximum access

• Giving users only the access they need

• Allowing all users to be administrators

• Disabling all user accounts

Why is zero trust important in organizations?

• It allows unrestricted access

• It provides unlimited access to all employees

• It ensures that every user must be verified

• It disables all security measures

What is role-based access control (RBAC)?

• A method to give all users the same access

• A method to assign permissions based on job roles

• A type of malware

• A network protocol

What does continuous monitoring in a zero trust model imply?

• Disabling all security measures

• Ignoring all security alerts

• Constantly checking and reporting on system security

• Allowing all users to access all systems
