TOP TECH INTERVIEW QUESTIONS, AND CYBERSECURITY Q&A
PART 1.
1. How would you define cybersecurity, and what makes it crucial? Cybersecurity
is
the practice of securing systems, networks, and data from
unauthorized access, attacks, or damage. It plays a critical role in
maintaining the confidentiality, accuracy, and accessibility of
information, helping to protect organizations from data breaches,
financial loss, and cyber threats.
2.
What does the CIA triad stand for, and why is it important? The CIA triad
consists
of three key components: Confidentiality, Integrity, and
Availability. These principles guide cybersecurity practices by ensuring
that sensitive data remains private, unaltered, and accessible to authorized
users when needed.
3.
Can you explain the difference between a vulnerability, a threat, and a
risk?
Vulnerability: A system weakness that could be exploited by an attacker.
•
•
Threat: Any event or action with the potential to cause harm to a
system or data. •
Risk: The potential impact and likelihood of a threat exploiting a
vulnerability.
4.
How do you stay current with evolving cybersecurity trends?
I keep up with industry advancements by reading cybersecurity blogs,
subscribing to newsletters, attending webinars, and participating in
conferences and online communities.
, 5.
What are the primary layers of security within a system?
The main security layers include network security, application security,
data security, endpoint protection, and physical security. These layers
work together to establish a robust defence strategy.
6.
What is multi-factor authentication (MFA), and why is it valuable?
MFA is a security measure that requires users to verify their identity
through two or more factors, such as a password (something you know), a
physical token (something you have), or biometrics (something you are).
It reduces the risk of unauthorized access by adding multiple layers of
security.
7.
What do you mean by “Defence in Depth”? Defence in Depth is a
cybersecurity
strategy that employs multiple layers of security
controls. Each layer adds redundancy, making it more challenging for
attackers to compromise the entire system.
8.
How do authentication and authorization differ?
Authentication confirms the identity of a user or system.
•
is
•
Authorization determines what actions or resources an
authenticated user permitted to access.
9.
What is a security policy, and why is it essential? A security policy is a
formal set of
guidelines and rules designed to protect an
organization’s IT assets. It ensures compliance, mitigates risks,
and provides a framework for responding to security incidents.
