It's some device keeping track of another device or a connection. Ex: When I'm in a forum with my username and password,and accidentally exit the internet browser. After two minuts i re-open the same URL or typed the forum address. I will enter the forum without re-typing my username and password, because it remembered them. It's like cookie.

What are some weaknesses of a packet-filtering router?
The weaknesses of static (or stateless) packet filters and stateful packet filters are different in a few ways. Stateless packet filters frequently block SYN scans of networks, but .... Stateless packet filters. (cf. iptables connection tracking), cf. state vs. stateless discussion. confounded application layer protocols like FTP, H323 Because of the nature of connection tracking and state awareness, stateful packet filters are vulnerable to resource exhaustion and deliberate attempts to trip rate-limiting features.
A stateful firewall uses what type of access control?
Context-dependent access control
What does intermittent connection to the internet stand for?
It means that the connection to the Internet is not consistant. This may be caused by a loose wire or other connection, some other hardware problem, or if your connection is shared, there may be enough traffic going through the connection that your machine isn't able to maintain a solid connection to a machine outside of the network.
What is Connectionless and Connection Oriented?
Connection-Oriented means that when devices communicate, they perform handshaking to set up an end-to-end connection. Connection-Oriented systems can only work in bi-directional communications environments. Connection-less means that no effort is made to set up a dedicated end-to-end connection. Walkie-talkies, or Citizens Band radios are a good examples of connection-less communication.
Is Ethernet connection faster than USB connection?
Depending on what kind of data is being uploaded, either connection could be faster than the other.
Which firewall feature is used to track communication channels and provides additional security for connectionless protocols?
Stateful Inspection. A stateful inspection firewall uses a technique known as stateful packet filtering to keep track of communication channels. This is different when compared to basic firewalls. Once the packet and connection has been sent, a normal firewall will not remember the communication channel, whereas the stateful inspection firewall will. This also proves useful to protect connectionless communication protocols.
What type of Packet filtering keeps a record of the state of a connection between an internal computer and an external server and then makes decisions based on the connection as well as the rule base?
stateful packet filtering
What layer does stateful inspection work at?
Stateful inspection works at Network Layer . Many Thanks, Chinmoy Roy
A company wants to configure a firewall to monitor all channels of communication and allow only traffic that is part of a known connection Which firewall configuration should be deployed?
stateful packet inspection
If a connection is is the state table what action will occur with future traffic for that connection?
If a connection is present in the state table, it typically indicates that the connection is established and recognized by the firewall or router. Future traffic for that connection will be allowed to pass through without needing to undergo further inspection or filtering, as it is considered part of an ongoing session. This process is known as stateful packet inspection, which helps improve network efficiency and performance.
Is there a potential for a denial of service attack against a stateful firewall that would not occur in a stateless firewall?
Stateful firewalls use session-based rules to control traffic. The disadvantage of a stateful firewall is that it can be vulnerable to Denial of Service (DoS) attacks if a lot of new connections are opened very fast.
How does a DoS attack take advantage of the stateful condition of target systems?
A Denial of Service (DoS) attack exploits the stateful condition of target systems by overwhelming them with excessive requests or traffic, causing them to become unable to process legitimate requests. Stateful systems maintain information about ongoing connections, which makes them vulnerable when flooded with numerous connection attempts that exceed their capacity. This flood can exhaust system resources like memory and processing power, leading to service disruptions or crashes. As a result, legitimate users are denied access to the service, fulfilling the attack's objective.
Which company manufactured stateful multi level firewalls?
cisco

What firewall keeps track of the state of the state of network connections traveling through the firewall?
The method you are referring to is called SPI - Stateful Packet Inspection. A firewall employing SPI is commonly called a stateful firewall.
What firewall operates at the highest level of the OSI m?
Stateful packet inspection
Which firewall technique blocks incoming packets unless they are responses to internal requests?
The firewall technique that blocks incoming packets unless they are responses to internal requests is known as stateful inspection or stateful packet filtering. This method tracks the state of active connections and only allows packets that are part of a recognized connection or are responses to outbound requests. By maintaining a state table, it can distinguish between legitimate traffic and potential threats, enhancing network security.
