Vulnerability means a weakness in the system, which can be exploited by the attacker or the hackers.
Q4. Explain the Firewall and set-up of Firewall?
Answer:
This is the common Cyber SecurityInterview Questions asked in an interview. A firewall is referred to as a security system or network to protect computers from unauthorized access. It helps in monitoring the network and to check which traffic needs to allow or block. There are few steps to set up the firewall:
- The new username and password are set for the firewall device.
- A firewall is mainly used to disable the feature of remote administration.
- Then port enabling is done with the help of configuring the port so that applications can work properly.
- Installing a firewall on the network with existing DHCP servers.
- Logging has been enabled and understands to view the logs, and there should be configured security policies to enforce these policies.
Q5. Explain SSL and TLS?
Answer:
SSL referred to as secure socket layer, which helps in providing the secured conversation and helps in verifying the person. It also combines with HTTP to use the internet safely with encryption of data. Its main use is to just get the identity information of the sender apart from that, no other information can be viewed. TLS is referred to as Transport layer security, which is a protocol that provides privacy and data integrity for the different applications. It is mainly used to provide more protection to confidential and sensitive data.
Part 2 – Cyber Security Interview Questions (Advanced)
Let us now have a look at the advanced Questions and Answers.
Q6. How can identity theft be prevented?
Answer:
It can be prevented with the help of providing or using a unique username and password, do not share confidential information online.

Q8. Explain DDoS attacks?
Answer:
DDoS is abbreviated as a distributed denial of service. It is used to make the server unavailable for the legal request as sometimes network or servers are occupied with a request in many numbers, which are not able to handle and recognized. The request can come to from a different source that is called a distributed denial-of-service attack. These attacks can be mitigated with the help of identifying the network conditions in normal. It can be done in scrubbing centers, where the traffic has been analyzed in such a manner that irrelevant traffic can be identified and removed.
