Automatic Data Processing (ADP) Application Security Analyst Interview Questions and Answers

Firewall is a security system that monitors and controls incoming and outgoing network traffic, while a gateway is a node that connects two different networks.

• Firewall is a security system that filters network traffic based on predetermined security rules.

• Gateway is a node that acts as an entry and exit point for data between two networks.

• Firewall can be a software program or a hardware device, while gateway is typical...read more

To mitigate DOS and DDOS attacks, implement network security measures such as firewalls, intrusion detection systems, and rate limiting.

• Implement firewalls to filter out malicious traffic

• Use intrusion detection systems to detect and block suspicious activity

• Implement rate limiting to prevent overwhelming the network with excessive requests

Kerberos protocol is a network authentication protocol that allows individuals communicating over a non-secure network to prove their identity to one another in a secure manner.

• Developed by MIT in the 1980s

• Uses symmetric key cryptography

• Involves a Key Distribution Center (KDC)

• Prevents eavesdropping and replay attacks

Three-way handshake is a method used in TCP/IP network to establish a connection between a client and a server.

• Client sends a SYN (synchronize) packet to the server to initiate a connection

• Server responds with a SYN-ACK (synchronize-acknowledgment) packet to acknowledge the request

• Client sends an ACK (acknowledgment) packet back to the server to confirm the connection

TLS (Transport Layer Security) is a protocol that ensures privacy and data integrity between communicating applications.

• TLS encrypts data to ensure confidentiality during transmission.

• It uses cryptographic algorithms to authenticate the parties involved in the communication.

• TLS also provides mechanisms for data integrity to prevent tampering.

• Handshake process involves negotiation of encryption algorithms and exchange o...read more
