    1) Eavesdropping: It can be defined as secretly listening to the private conversation of others without their consent. Here an attacker can choose to passively eavesdrop on the network communication and steal the data. Through passive eavesdropping attackers apparently eliminate their presence in the network and make such attacks difficult to detect. The goal of such an attack is to violate the confidentiality of the communications by intercepting the network and sniffing or listening to the routing packets. Also, an adversary can actively influence the communication channel by disrupting, jamming or modifying the network packets and/or inserting false packets into the network. Jamming happens at physical layer which can cause intermission and make the communication impossible. Using a strong encryption and decryption technique one can obtain strong protection against eavesdropping. Proper authentication and integrity mechanisms can also be useful. On the other hand, a standard defense against jamming includes various forms of spread-spectrum and frequency-hopping communications and maintaining a low-duty cycle, locating a jamming area, and rerouting transmissions. 2) Denial of Service: Dos is an attack where the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to the Internet.
