Top Interview Questions to Master as a CompTIA
Security Certified Professional
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
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.
Question 1 What can you do to defend yourself
from multiple login attempts? Answer You can set
up a lockout policy that prevents users from
logging in after a certain number of failed
attempts. Question 2 Would you prefer Windows
or Linux as your operating system? Answer 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. Question 3 What Is
the Purpose of a Firewall? Answer A firewall is
a security device that can help safeguard your
network by filtering traffic and preventing
outsiders from having unauthorized access to your
computers confidential data. It can be either
hardware or software.
Question 4 What do you understand about
Gateway? Answer 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. Question 5
Determine the difference between a gateway and a
router. Answer 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.
Question 6 What is Cross-Site Scripting (XSS),
and how does it work? Answer 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. Question 7
What methods will you use to keep track of
malicious activity on our systems? Answer 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. Question 8
What is the purpose of port 443? Answer Computers
utilize port 443 as a virtual port to divert
network traffic. Port 443 is used for HTTPS
(Hypertext Transfer Protocol Secure).
Question 9 What is the OSI model, and what are
the different layers of the OSI
model? Answer 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 model
Question 10 What is a Protocol
Analyzer? Answer 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. Question 11 What exactly is
HIDS? Answer A Host-Based Intrusion Detection
System (HIDS) is a type of intrusion detection
system that can monitor and analyze a computers
internals and network traffic passing through its
network ports. Question 12 What is a Proxy, and
how does it work? Answer 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.
  • Question 13 What can you do to keep a VPN
    connection secure?
  • Answer A secured tunneling protocol is the best
    technique to secure a VPN connection. There are
    numerous options available, but you must select
    the most acceptable option for your digital
  • Question 14 What are some good security
    practices for network devices?
  • Answer Some of the security practices are
  • Reduce the number of needless lateral
  • 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
  • Question 15 What is the difference between MAC,
    DAC, and RBAC?
  • Answer The MAC makes decisions based on labeling
    and permissions, whereas the DAC considers
    permissions. RBAC, on the other hand, makes
    decisions based on functions and roles.
  • Question 16 How can you stop a phishing attack?
  • Answer These are some ways to protect from
  • Know how to spot a phishing scam
  • Do not click on any link without knowledge
  • Do not give your personal information to a
    website that is not secure
  • Change your passwords frequently
  • Install firewalls
  • Get free anti-phishing add-ons
  • Do not be swayed by those pop-ups
  • To detect signs of an attack, use a data security
  • Question 17 What is unified threat management?
  • Answer Unified Threat Management (UTM) refers to
    an information security system that protects
    against threats like viruses, spyware, worms, and
    other malware, as well as network attacks,
    through a single point of protection.
  • Question 18 What is an Access Control List?
  • Answer Access Control List (ACL) is a set of
    rules used to filter 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.
  • Question 19 What are the types of Cross-Site
  • Answer The three types of Cross-Site Scripting
  • 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-based XSS In DOM-based XSS, the
    vulnerability is found in client-side code rather
    than server-side code.
Question 20 What are some of the ways the
organization may protect itself from
XSS? Answer 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
