After the characteristics are determined, the UDP attack packets can be filtered based on them. Characteristic filtering, also known as fingerprint filtering, can customize the filtering attributes according to the characteristics of attack packets. It includes static fingerprint filtering and dynamic finge...
What is RSTP in networking? What are the different wireless local area network protocols? Explain why the MAC protocol is more important in a wireless LAN than in a wired LAN. What is the difference between TCP and UDP? Why was the OSI model developed? What is the purpose of data securit...
How is a botnet controlled? A core characteristic of a botnet is the ability to receive updated instructions from the bot herder. The ability to communicate with each bot in the network allows the attacker to alternate attack vectors, change the targeted IP address, terminate an attack, and ot...
For a UDP flow, the port number of the campus network path is reused. The TTL value starts from that of a campus edge device and increases by 1 hop by hop. One detection packet is sent at each hop. When timeouts occur at 10 consecutive hops or the TTL value reaches the upper limit...
From TCP connection setup to teardown only the packets used for TCP connection establishment can have the ACK value of 1 and RST value of 1. According to this characteristic, configure the following ACL rules to permit the packets used for establishing TCP connections and deny other TCP packets...
According to this characteristic, configure the following ACL rules to permit the packets used for establishing TCP connections and deny other TCP packets on the network segment 192.168.2.0/24. In this way, you can limit the TCP connection requests initiated from this network segment. Rule 1: ...
What are the two main components on the motherboard? What is a characteristic of a wan? Choose one of the options and, when required, please explain your answer. 1. Routers operate at (a) Layer 2 (b) Layer 3 (c) None of the Above 2. Suppose there is exactly one packet switch bet...
As stated earlier, TCPdump holds the potential to capture a large number of packets, including those that may not be suitable for the characteristic troubleshooting task. For illustration, when troubleshooting a connectivity issue with a web server, SSH traffic might not be of interest. By filteri...
Network CharacteristicDescription Bandwidth The rate at which traffic is carried by the network. Latency The delay in data transmission from source to destination. Jitter The variation in latency. Reliability The percentage of packets discarded by a router. The Internet Engineering Task Force (IETF)...
Reliability is a core characteristic of TCP. To guarantee the accurate transmission of data, TCP employs various mechanisms, including acknowledgment packets and retransmission of lost or corrupted data. This meticulous approach ensures that information arrives intact, minimizing the risk of errors during...
