According to reports, cybercrime now poses a risk to billions of dollars in assets and data. In today’s world, there are so many access points, public IPs and constant traffic. There is also a lot of data to exploit. Hackers have a lot of time to exploit weaknesses and create malicious software for sale. Cybersecurity professionals are highly sought after in all industries.

There are several cybersecurity-certified professionals in the market today. CompTIA Security+ certification gives you the opportunity to learn core cybersecurity skills. These are the most recent interview questions and answers for CompTIA Security+-certified professionals who are applying for a cybersecurity job.
Question 1: How can you defend yourself against multiple login attempts?
Answer: After a certain number failed attempts, you can create a lockout policy to prevent users from logging into your site.
Question 2: Do you prefer Linux or Windows as your operating system?
Answer: This question doesn’t have an ideal answer. Both operating systems must be well-understood. Linux is, as we all know to be far more secure than Windows and virus-free. Before you give your answer, be sure to explain in detail the pros and cons of each Operating System.
Question 3: What is the purpose of a Firewall
Answer: A firewall is a security tool that protects your network by filtering traffic, and prevents outsiders having unauthorised access to your computer’s private data. It can be hardware or software.
Question 4: What do YOU know about Gateway?
Answer: A gateway is a router or computer network node that acts as a critical stopover point to ensure data flows smoothly between networks. Gateways allow us to communicate and send data back-and-forth. Without gateways, the Internet wouldn’t exist.
Question 5: Identify the difference between a router and a gateway.
Answer: A router is a layer of computer networking that manages and forwards data packets. A gateway is simply a piece of hardware or device that acts as a “gateway” between networks. Another term for a gateway is a network node that acts as an entry point to other nodes.
Question 6: What is Cross-Site Scripting? How does it work?
Answer: Cross-Site Scripting is a web security flaw that allows an attacker manipulate the user’s interaction with a vulnerable application. It will allow an attacker to bypass the same-origin policy that keeps websites apart. These are injection attacks, in which malicious scripts are embedded into otherwise trusted and simple websites.
Question 7: Which methods will you use for keeping track of malicious activity?
Answer: DLP, SIEM and NBAD can all be used to detect malicious activities. Some tools are evolved from others while others are more specific to detect malicious behavior. They are all intended to help you detect malicious activity on your system, and alert your IT staff so that appropriate response can be initiated.
Question 8: What’s the purpose of port 443, you ask?
Answer: Computers use port 443 to divert network traffic. Port 443 is used to transmit HTTPS (Hypertext Transfer Protocol Secure).
Question 9: What’s the OSI model and what are its different layers?
Answer: The Open Systems Interconnection (OSI Model) is a conceptual framework that describes the functions of a network system. The OSI model is a set of universal rules and standards that describes computing functions in order to facilitate interoperability among different devices and applications. In the OSI reference model, there are seven abstraction layers that describe the connections between computing systems.
