Question

can you please solve this answer 1) identify and describe the threats, vulnerabilities and attacks on Wireless Local Area Network (LAN), describe the scenario of each attack and its effect on wireless network performance. Also, clarify the attacks by diagrams)

(Hint: identify and describe the threats, vulnerabilities and attacks on your selected wireless network, describe the scenario of each attack and its effect on wireless network performance. Also, clarify the attacks by diagrams)

2) Suggest security services and mechanisms to countermeasure the attacks. Provide a detailed description for each service and mechanism. Then, provide a clear diagram of your security architecture of wireless network.

(Hint: identify the security service that could detect/prevent the attack, then describe mechanisms to implement the identified services.)

Answer 1

Hi,

Please find some of the threats and vulnerabilities on WLAN.

1)

Bogus Access Point: Installing a fake or Bogus Access point on the network. Attack is to fool users with fake access points.

Denial of service attack: DoS occurs when hacker continually sends to a targeted access point or network with bogus requests.

Network injection: attacker injects bogus networking re-configuration commands that affects network devices such as routers, switches etc. With this kind of attack, A whole network can be brought down by the attacker.

Man-in-the-middle attack: Eavesdropping

MAC address spoofing or Identity Threat / Session Hijacking. This kind of attack allows a machine to pretend it as another MAC address that the attacker desires to spoof. Attackers can use spoofed frames to redirect legitimate traffic and corrupt address tables.

2)

Wireless network auditing is an effective countermeasure for the attacks. It is an important part of WLAN security policy.

Use of anti-virus software and firewall protects the devices in the network from the attacks.

Use of encryption: An effective way to secure wireless network from attackers is to encrypt

communications over the network.

Use of up-to-date software and network devices minimizes the risk of attacks.

Change all default passwords for the routers and default settings to network devices.
