What is network segmentation, and how does it improve security?
✔✔ Network segmentation involves dividing a network into smaller, isolated segments to reduce
the spread of security threats and limit access to sensitive information.
What is role-based access control (RBAC)?
✔✔ Role-based access control (RBAC) restricts access to systems and data based on the user’s
role within the organization, ensuring that users only have access to the resources needed for
their job.
What is a security audit?
✔✔ A security audit is a systematic evaluation of an organization’s security policies, procedures,
and infrastructure to ensure compliance with security standards and identify areas of
improvement.
What is the importance of logging in information security?
1
,✔✔ Logging records system and user activities, providing valuable data for detecting suspicious
behavior, auditing access, and investigating security incidents.
What is the role of data loss prevention (DLP) in security?
✔✔ Data loss prevention (DLP) technologies monitor, detect, and block sensitive data from
leaving the organization, ensuring compliance with data protection policies.
What is the purpose of encryption at rest?
✔✔ Encryption at rest protects stored data by converting it into an unreadable format that
requires a decryption key
What is the primary goal of information security?
✔✔ The primary goal of information security is to protect the confidentiality, integrity, and
availability of information from unauthorized access or modification.
What does confidentiality mean in the context of information security?
✔✔ Confidentiality ensures that information is only accessible to those authorized to view it,
preventing unauthorized disclosure.
2
,How does integrity contribute to information security?
✔✔ Integrity ensures that information remains accurate, consistent, and unaltered unless
authorized, safeguarding it from unauthorized changes.
What does availability mean in information security?
✔✔ Availability ensures that information and resources are accessible to authorized users when
needed, preventing disruptions in access.
What is the role of encryption in information security?
✔✔ Encryption is the process of converting plain text into a coded form to protect data from
unauthorized access, ensuring confidentiality during transmission or storage.
What is a security policy, and why is it important?
✔✔ A security policy is a formal document that outlines an organization’s rules and practices for
protecting information and resources, guiding employees on how to handle sensitive data.
What is the difference between authentication and authorization in security?
✔✔ Authentication verifies the identity of a user, while authorization determines what actions or
access levels the authenticated user is allowed.
3
, What is multi-factor authentication (MFA)?
✔✔ Multi-factor authentication (MFA) requires two or more verification methods, such as a
password and a fingerprint, to increase the security of user authentication.
What is a firewall, and how does it protect a network?
✔✔ A firewall is a security device that monitors and controls incoming and outgoing network
traffic based on predefined security rules, acting as a barrier between trusted and untrusted
networks.
What is the role of intrusion detection systems (IDS) in security?
✔✔ An IDS monitors network or system activity for malicious behavior or policy violations,
alerting administrators when potential threats are detected.
What is a vulnerability in the context of information security?
✔✔ A vulnerability is a weakness in a system or application that can be exploited by a threat
actor to gain unauthorized access or cause damage.
