Cybercrime, according to reports, now risks
billions of dollars of assets and data. We have
so many access points, public IPs, constant
traffic, and loads of data to exploit in todays
day and age. Hackers are having a lot of time to
exploit vulnerabilities and develop malicious
software for sale. As a result, cybersecurity
professionals are in huge demand across all
industries.

Top Cybersecurity Interview Questions
There are several cybersecurity-certified
professionals in the market today. But being
CompTIA Security certified offers you a chance
to learn core cybersecurity skills. So, if you
are a CompTIA Security certified professional
with a cybersecurity job interview coming up,
here are the latest interview questions and
answers you should master.
1
What can you do to defend yourself from multiple
login attempts You can set up a lockout policy
that prevents users from logging in after a
certain number of failed attempts.
2
Would you prefer Windows or Linux as your
operating system This question does not have an
ideal answer. You must have a thorough knowledge
of both operating systems. Linux, as we all
know, is regarded to be virus-free and far more
secure than Windows. Before you provide your
answer, make sure you explain the advantages and
disadvantages of each Operating System in depth

What Is the Purpose of a Firewall A firewall is a
security device that can help safeguard your
network by filtering traffic and preventing
outsiders from having unauthorized access to
your computer's confidential data. It can be
either hardware or software.

What do you understand about Gateway A gateway is
a computer network node or router that serves as
a critical stopover point for the data on its
way to or from other networks. We can
communicate and send data back and forth thanks
to gateways. Without gateways, the Internet would
be useless to us.
5
Determine the difference between a gateway and a
router A router is a computer networking layer
system that manages and forwards data packets. A
gateway, on the other hand, is merely a device
or piece of hardware that operates as a gate
across networks. It might alternatively be
described as a network node that serves as an
entry point for other nodes.
6
What is Cross-Site Scripting (XSS), and how does
it work Cross-Site Scripting (XSS) is a web
security vulnerability that allows an attacker
to manipulate how users interact with a
susceptible application. It will enable an
attacker to get around the same origin policy,
which keeps websites separate from one
another. They are injection attacks in which
malicious scripts are inserted into otherwise
trustworthy and simple websites.
What is the purpose of port 443 Computers utilize
port 443 as a virtual port to divert network
traffic. Port 443 is used for HTTPS (Hypertext
Transfer Protocol Secure).

What methods will you use to keep track of
malicious activity on our systems
IDS, IPS, DLP, SIEM, and NBAD are tools that can
be used to detect malicious activity. Some are
evolutions of others, and some are strictly
focused on specific types of behavior or
malicious activity. Still, they are all designed
to help you discover malicious activity on your
system and alert your IT staff so that the
necessary response may be initiated.

What is the OSI model, and what are the
different layers of the OSI model The Open
Systems Interconnection or OSI Model is a
conceptual framework for describing the
functions of a networking system. In order to
facilitate interoperability between various
devices and applications, the OSI model
describes computing functions into a universal
set of rules and standards. The connections among
computing systems are divided into seven
abstraction layers in the OSI reference

What is a Protocol Analyzer A Protocol Analyzer
is a Software that captures and monitors data
through a communication channel for possible
threats. It collects data from the communication
channel and converts the bits into a protocol
sequence that makes sense. It is also known as
Packet Sniffer.
11
What exactly is HIDS A Host-Based Intrusion
Detection System (HIDS) is a type of intrusion
detection system that can monitor and analyze a
computer's internals and network traffic passing
through its network ports.
What is a Proxy, and how does it work Any server
application that translates traffic between
networks or protocols is known as a proxy or
proxy server. It is an intermediary server that
sits between end-user clients and the websites
they visit.

What can you do to keep a VPN connection
secure A secured tunneling protocol is the best
technique to secure a VPN connection. There are

What are some good security practices for
network devices Some of the security practices
are
1 2 3 4 5
Reduce the number of needless lateral
communications
IP ranges that can manage network infrastructure
should be limited
Unused network ports should be disabled
Secure access to infrastructure devices
Verify the hardware and software integrity
15
What is the difference between MAC DAC, and
RBAC, The MAC makes decisions based on labeling
and permissions, whereas the DAC considers
permissions. RBAC, on the other hand, makes

network traffic, particularly in computer
security settings. ACLs also grant authorized
users access to particular system objects such as
directories or files while denying access to
unauthorized users.
19
What are the types of Cross-Site Scripting The
three types of Cross-Site Scripting
are Reflected XSS Reflected XSS is a type of
XSS in which the malicious script originates
from the current HTTP request. Stored XSS The
malicious script is stored XSS, and it comes from
the websites database. DOM-b6sed XSS In
DOM-based XSS, the vulnerability is found in
client-side code rather than server-side code.
20
What are some of the ways the organization may
protect itself from XSS To start, programmers
should guard against the addition of JavaScript
to a query string. Also, any input variables sent
through web forms and saved in a database should
be free of JavaScript. In addition, you can look
through a variety of other interview questions
for CompTIA Security certified professionals to
broaden your preparations. You can acquaint
yourself with diverse formats and tones of
questions by checking multiple sources of
interview questions.
