Question

Six months after your initial posture assessment, the credit union’s manager contacts you to
conduct a follow-up security audit. He mentions that his networking team followed your
suggestions for improving the LAN and WAN security. However, since then, several wireless
components have been added to the network, including an access point at each of its two
locations. These access points allow employees to connect with the LAN and another access
point at each of its locations designated for customer access. The manager doesn’t even know
if wireless security measures have been implemented, much less whether any measures
that might have been implemented are as secure as possible.

Describe at least three separate techniques that could be used to improve wireless LAN security.

Answer 1

Answer)
Information security is very important in today's world where computers and networks handle all data. This malicious activities such as hacking a data leakages are prevalent and are abundant in activities by the attackers who perform attacks and try to access unauthorized or secure content from computers or networks. There are separate techniques that could be used to improve wireless LAN security such as:
Wired Equivalent Privacy (WEP): is an old encryption standard which is used to overcome security threats by encrypting the information which is transmitted over the air such that the receivers having the correct encryption key should be able to decrypt the information which was encrypted by a key.
WPA/WPA2 (WI-FI Protected Access) is an improved version over the WEP which uses Temporal Key Integrity Protocol (TKIP). This method uses a temporal encryption key that is regularly renewed which makes it more difficult to steal the key. A more robust hashing mechanism also improved the data integrity.
Wireless Intrusion Prevention Systems/Intrusion Detection Systems uses the radio frequency (RF) levels and detects the rogue access points or ad hoc networks to regulate network access. Latest tools and features include to visually represent the network area along with potential threats and have automatic classification capabilities to identify the threats.
