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.

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.

    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:

  • Configure firewalls and routers
  • Empower the server with scalability and load balancing
  • Use anti-DDoS software
