Movate Network Security Engineer Interview Questions, Process, and Tips

DHCP is a network protocol that dynamically assigns IP addresses to devices on a network. DORA process involves Discover, Offer, Request, and Acknowledge stages.

• DHCP Discover: Client broadcasts a request for IP address

• DHCP Offer: Server responds with an available IP address

• DHCP Request: Client requests the offered IP address

• DHCP Acknowledge: Server confirms the IP address assignment

A personal computer communicates with a web application through a series of steps involving network protocols.

• The computer sends a request to the web application's server using the HTTP protocol.

• The server processes the request and sends back a response containing the requested information.

• The communication is facilitated by the TCP/IP protocol stack.

• Data is transmitted over the internet using IP addresses and domain n...read more

SSL handshake is a process where a client and server establish a secure connection by exchanging encryption keys and verifying identities.

• Client sends a hello message to server with supported encryption algorithms

• Server responds with its own hello message, including its certificate

• Client verifies server's certificate and generates a pre-master secret

• Both client and server use the pre-master secret to generate a unique ...read more

ARP (Address Resolution Protocol) is a protocol used for mapping an IP address to a MAC address.

• ARP is used to resolve IP addresses to MAC addresses on a local network.

• There are two main types of ARP: ARP Request and ARP Reply.

• ARP Request is sent by a device to find the MAC address of another device with a known IP address.

• ARP Reply is sent in response to an ARP Request, providing the MAC address of the requested IP ad

Types of ARP include ARP request, ARP reply, ARP probe, and ARP announcement.

• ARP request is used to find the MAC address of a device on the network.

• ARP reply is the response to an ARP request, providing the MAC address of the target device.

• ARP probe is used to check if an IP address is already in use on the network.

• ARP announcement is used to inform other devices on the network about a change in MAC address.

Yes, TCP Header Flags are used to control the flow of data between devices.

• TCP Header Flags are 6 bits long and are used to control the flow of data between devices.

• There are 6 TCP Header Flags: URG, ACK, PSH, RST, SYN, and FIN.

• URG is used to indicate that the data is urgent and should be prioritized.

• ACK is used to acknowledge receipt of data.

• PSH is used to push data to the receiving device.

• RST is used to reset the con...read more

PUSH flag is used to indicate the start of a new TCP session while URG flag is used to indicate urgent data.

• PUSH flag is set when a sender wants to push data to the receiver without waiting for a full buffer

• URG flag is set when a sender wants to indicate that some data is urgent and should be processed immediately

• PUSH flag is used to initiate a new session while URG flag is used to indicate the presence of urgent data

TLS Handshake is a process of establishing a secure connection between a client and a server.

• TLS Handshake involves a series of steps to establish a secure connection

• It includes negotiation of encryption algorithm, exchange of keys, and verification of digital certificates

• TLS Handshake ensures confidentiality, integrity, and authenticity of data transmitted over the network

• Examples of applications using TLS Handshake a
