RST

Sam is a penetration tester hired by Inception Tech, a security organization. He was asked to perform port scanning on a target host in the network. While performing the given task, Sam sends FIN/ACK probes and determines that an RST packet is sent in response by the target host, indicating that the port is closed. What is the port scanning technique used by Sam to discovers open ports?

Bob

Samuel, a professional hacker, monitored and intercepted already established traffic between Bob and host machine to predict Bob’s ISN. Using this ISN, Samuel sent spoofed packets with Bob’s IP address to the host machine. The host machine responded with a packet having an incremented ISN. Consequently, Bob’s connection got hung, and Samuel was able to communicate with the host machine on behalf of Bob. What is the type of attack performed by Samuel in the above scenario?

IDS

Kevin, a professional hacker, wants to penetrate CyberTech Inc.’s network. He employed a technique, using which he encoded packets with Unicode characters. The company’s IDS cannot recognize the packet, but the target web server can decode them. What is the technique used by Kevin to evade the IDS system?

Understand Evidence Gathering via Sniffing in this aerticle a computer connected to the LAN has two addresses. One is that the MAC address that specifically identifies each node within the network and is stored on the network card itself. The ethernet protocol uses the MAC address while building “frames” to exchange the info among the systems. the opposite is that the IP address employed by the applications. The data-link layer uses an ethernet header with …

Overview of Network Layer Functions

Leave a Comment / CCNA / By

Overview of Network Layer Functions Many protocol models have existed over the years, but today the TCP/IP model dominates. And at the network layer of TCP/IP, two options exist for the most protocol around which all other network layer functions revolve: IP version 4 (IPv4) and IP version 6 (IPv6). Both IPv4 and IPv6 define the same sorts of network layer functions, but with different details. This chapter introduces these network layer functions for IPv4, …
