This attack exploits the feature of some network services to generate a new process each time a new TCP/IP connection is set up. |
|
|
Attacker creates a packet that contains more than 65,536 bytes. This packet can cause different kinds of damage to the machine that receives it, such as crashing and rebooting. |
|
|
This attack makes hundreds of connections to the victim with the Secure Shell (SSH) Protocol without completing the login process. |
|
|
The victim's mail queue is flooded by an abundance of messages, causing system failure. |
|
|
The attacker sends an abundance of TCP SYN packets to the victim, obliging it both to open a lot of TCP connections and to respond to them. |
|

Выберите по крайней мере один ответ:
|
By having the ability to "remember" the status of a connection, this method of packet screening is better equipped to guard against attacks than standard packet filtering. |
|
|
Rules and filters in this packet screening method can become complex, hard to manage, prone to error and difficult to test. |
|
|
Like packet filtering, stateful packet inspection does not break the client/server model and therefore allows a direct connection to be made between the two endpoints |
|
|
Stateful packet inspection compares the packets against the rules or filters and then checks the dynamic state table to verify that the packets are part of a valid, established connection. |
|
|
The packets are compared to pre-configured rules or filters and allow or deny decisions are made based on the results of the comparison. |

150. A function that maps a variable-length data block or message into a fixed-length value called a hash code. The function is designed in such a way that, when protected, it provides an authenticator to the data or message. Also referred to as a message digest.
