Solution
-
Network-level Denial of Service (DoS) attacks target Network bandwidth.
-
The statements that accurately describe Denial of Service (DoS) and Distributed Denial of Service (DDoS) attacks are:
- A DoS attack targets a network or server.
- In both DoS and DDoS attacks, if any part of the network is overloaded, the attacks are successful.
- A DDoS attack may use multiple devices in different locations to flood the target network with unwanted traffic.
-
An indication that an organization is at risk of a SYN-flood attack is when the server has stopped responding after receiving an unusually high number of incoming SYN packets.
-
The DoS attack that occurs when a malicious actor sends an oversized ICMP packet to a server is called Ping of Death.
-
The statements that correctly describe passive and active packet sniffing are:
- Active packet sniffing may enable attackers to redirect the packets to unintended ports.
- A company can avoid using unprotected Wi-Fi to help protect itself from packet sniffing.
- Passive packet sniffing allows malicious actors to view the information going in and out of the targeted device.
-
The type of network attack you are trying to avoid by implementing safeguards against attackers changing the source IP of a data packet in order to communicate over your company’s network is IP spoofing.
-
IP spoofing is a network attack performed when an attacker changes the source IP of a data packet to impersonate an authorized system and gain access to a network.
-
In an On-path attack, malicious actors gain access to a network, put themselves between a web browser and a web server, then sniff the packet to learn the devices’ IP and MAC addresses.
-
The Replay network attack occurs when an attacker intercepts a data packet in transit, then repeats it at another time.
-
A Smurf attack is a combination of DoS and IP spoofing attack that can bring down an entire network by flooding an authorized user’s IP address with packets.
