TCP/IP Protocol Vulnerabilities

which type of attack substitutes a secure IP address to impersonate a legitimate a computer system?

• ARP Spoofing

• IP Spoofing

• Buffer overflow

• Man-in-the-middle

• Port Scanning

• Threat actors try to predict TCP sequences to imitate the original sender and insert false and malicious packets.

• IP Spoofing

• Threat actors send false ARP messages to pass a MAC (media access control) address off as a legitimate IP address within the network.

• TCP sequence prediction

• Threat actors use malware to identify open and closed ports on internet-connected devices.

• Ping

• Threat actors alter IP packets with false source IP addresses that impersonate another computer system.

• Arp Spoofing

• Threat actors try to overwhelm the target system by echo request packets.

what happens during a source route attack

• Threat actors try to spoof the source IP address of a client and redirect their system to send the same data repeatedly to a targeted server with a malicious payload.

• Threat actors gain access to the source path and modify the options in the route for a data packet to take.

• Threat actors try to create a flood of half-opened sessions awaiting replies that will not come and thus deny any new connections on the target computer.

• Threat actors try to guess the sequence of numbers that TCP assigns to a stream of data packets for malicious intent.

In a ​ (a)   attack, threat actors will spoof the source address of the ICMP packet and send a broadcast to all computers on that network to generate enough broadcast traffic to compromise the network.

​ (b)   _____ is a technique used to exploit the vulnerability in the ICMP echo packet to obtain details of the operating system on the target computer.

A(n) ​ ​ ​ (c)   attack is when threat actors exploit overlapping IP fragments present in the target system. When the destination target tries to reassemble them, it cannot do so and fails, which causes the target system to reboot or crash.
