What Is A Firewall
It is a security system designed for the network. A firewall is set on the boundaries of any system or network which monitors and controls network traffic. Firewalls are mostly used to protect the system or network from malware, worms, and viruses. Firewalls can also prevent content filtering and remote access.
Question #: How Would You Keep A Server And Network Secure
Cyber criminals typically steal data from compromised servers and networksemployers want to know that you have experience preventing these data breaches. Be sure to discuss key security best practices and the approach you’ve taken to protect servers and networks. Use the following factors to answer these types of cyber security interview questions:
- Technical methods for securing servers and networks.
- User authentication.
- Monitoring login attempts.
How You Could Answer
“I always follow best practices when securing computer networks and servers. First and foremost, it’s critical to establish a secure connection by creating a strong router password, using encryption, setting up a VPN, and ensuring that Wi-Fi connections are secure. I would also establish a strong authentication system to protect logins and other sensitive information through a program such as Google Authenticator or WatchGuard AuthPoint. I also have experience using intrusion prevention programs such as McAfee and Cisco to monitor login attempts, especially for root users.”
What Do You Mean By A Vpn
A virtual private network establishes a protected network connection when using a public network. A VPN can encrypt internet traffic in real-time, thereby securing data that travels across the network and preventing third parties from tracking user activity. VPNs redirect a users IP address through a remote host server, allowing for IP address concealment.
What is the difference between VA and PT ?

How Do You Differentiate Between Symmetric And Asymmetric Encryption
While symmetric encryption uses a single key for encryption and decryption, asymmetric encryption uses a public key for encryption and a private key for decryption. The success of symmetric encryption necessitates a secure exchange of the key, and the technique is typically used to transfer large volumes of data. Asymmetric encryption is a slower but more secure technique that is generally deployed to transfer small amounts of data. While symmetric encryption offers confidentiality, asymmetric encryption guarantees confidentiality as well as authenticity and non-repudiation.
What Do You Mean By Xss
Cross-site scripting is a type of cyberattack that injects malicious scripts into legitimate websites. XSS attacks use web applications to send these fragments of codetypically as browser-side scriptsto oblivious end users whose browsers execute the malicious script because it appears to originate from a trusted source.

What do you infer from this situation? Justify.
All three newsletters probably have the same parent company or are distributed through the same service. The parent company or service can combine individual pieces of seemingly-harmless information and use or sell it for identity theft
It is even possible that there is a fourth newsletter that asks for a day of birth as one of the activation questions

What Is Cognitive Security
Cognitive security is one of the applications of AI technologies that is used explicitly for identifying threats and protecting physical and digital systems based on human understanding processes.
Self-learning security systems use pattern recognition, natural language processing, and data mining to mimic the human brain.
Ids Vs Ips: What Is The Difference
Intrusion detection systems monitor networks for suspicious activity. When a potential threat is detected, the system will alert the administrator. Intrusion Prevention Systems are equipped to respond to threats, and are able to reject data packets, issue firewall commands, and sever connections. Both systems can operate on a signature or anomaly basis. Signature-based systems detect attack behaviors or signatures that match a preprogrammed list, while anomaly-based systems use AI and machine learning to detect deviations from a model of normal behavior.

Explain The Ddos Attack How To Prevent It
Distributed denial-of-service attack overwhelms the target website, system, or network with huge traffic, more than the servers capacity. The aim is to make the server/website inaccessible to its intended users. DDoS happens in the below two ways:
Flooding attacks: This is the most commonly occurring type of DDoS attack. Flooding attacks stop the system when the server is accumulated with massive amounts of traffic that it cannot handle. The attacker sends packets continuously with the help of automated software.
Crash attacks: This is the least common DDoS attack where the attacker exploits a bug in the targeted system to cause a system crash. It prevents legitimate users from accessing email, websites, banking accounts, and gaming sites.
To prevent a DDoS attack, you have to:

What Exactly Is A Three
A three-way handshake is a mechanism for connecting a host and a client in a TCP/IP network. A three-way handshake is so named because it is a three-step technique in which the client and server exchange packets. The following are the three steps:
- The client sends an SYN packet to the server to see whether the server is up and running or if any ports are available.
- If the server has open ports, it sends an SYN-ACK message to the client.
- The client responds by sending an ACK packet back to the server.
