VPN just encapsulates the transmit network data over another network. VPN is a Virtual Private Network that is used to maintain anonymity and privacy on the internet by creating a private network from the public connection. There are 2 ways to deal with these types of attacks either to stay off or donРІР‚в„ўt connect to a public WiFi network or to use end-to-end encryption. A MITM attack happens when a third party is intercepting the network, monitoring and controlling the information between two parties. How do you deal with РІР‚СљMan-In-The-Middle AttacksРІР‚Сњ?Р”Р„ns. Using HTTPS instead of HTTP gives us protection against MITM attacks. Because HTTP sends the data in clear text and it can be clearly readable if someone is intercepting the network And the HTTPS sends the data in an encrypted format. Can you provide a reason why to use https instead of http?Р”Р„ns. DHCP Snooping which is a Layer 2 switch features is helpful to prevent all the denial-of-service from rouge DHCP server. Which features on a network switch can be used to prevent rouge DHCP servers?Р”Р„ns. DHCP server just provides the IP address and other information to all the hosts in the network to make the communication efficient. DHCP is a Dynamic Host Configuration Protocol, it is a networking protocol that is used on IP networks. Firewalls are important because they keep the attackers and external threats outside of the network. It can be of any type of hardware or software. Firewalls have the power to block or allows the traffic to pass through. A firewall is a system designed to prevent unauthorized access in a network. What are firewalls? and why are they so important?Р”Р„ns.

There can be a huge impact on the company. What are the outcomes of the network security attacks?Р”Р„ns. Network Security is designed to ensure the integrity and usability of the network. Network Security protects the network from all the security threats like data breaches, intrusion, misuse of the information, Denial of the computer. The First thing Interviewer wants to know what you know about the job. So, this list will contain all the technical questions that maybe asked in the interview. Why do you want to become a network security engineer?, WhatРІР‚в„ўs your background?, Tell me something about you?, etc.
