A new wireless client is configured to join a 802.11 network. This client uses the same hardware and software as many of the other clients on the network. The client can see the network, but cannot connect. A wireless packet sniffer shows that the Wireless Access Point (WAP) is not responding to the association requests being sent by the wireless client. What is a possible source of this problem?
In an attempt to damage the reputation of a competitor organization, Hailey, a professional hacker, gathers a list of employee and client email addresses and other related information by using various search engines, social networking sites, and web spidering tools. In this process, she also uses an automated tool to gather a list of words from the target website to further perform a brute-force attack on the previously gathered email addresses. What is the tool used by Hailey for gathering a list of words from the target website?
You are the Network Admin, and you get a complaint that some of the websites are no longer accessible. You try to ping the servers and find them to be reachable. Then you type the IP address and then you try on the browser, and find it to be accessible. But they are not accessible when you try using the URL. What may be the problem?

You are the chief cybersecurity officer at CloudSecure Inc., and your team is responsible for securing a cloudbased application that handles sensitive customer data. To ensure that the data is protected from breaches, you have decided to implement encryption for both data-at-rest and data-in-transit. The development team suggests using SSL/TLS for securing data in transit. However, you want to also implement a mechanism to detect if the data was tampered with during transmission. Which of the following should you propose?

A.
Implement IPsec in addition to SSL/TLS.
Answers
A.
Implement IPsec in addition to SSL/TLS.
B.
Qswitch to using SSH for data transmission.
Answers
B.
Qswitch to using SSH for data transmission.
C.
Use the cloud service provider's built-in encryption services.
Answers
C.
Use the cloud service provider's built-in encryption services.
D.
Encrypt data using the AES algorithm before transmission.
Answers
D.
Encrypt data using the AES algorithm before transmission.
Suggested answer: A

Explanation:

SSL/TLS is a protocol that provides encryption and authentication for data in transit between a client and a server. However, SSL/TLS does not provide any protection against data tampering, which is the alteration, deletion, or insertion of data without authorization or proper validation. Data tampering can compromise the integrity and accuracy of the data, and potentially lead to breaches or fraud. To detect and prevent data tampering, you should implement IPsec in addition to SSL/TLS. IPsec is a protocol that provides encryption, authentication, and integrity for data in transit at the network layer. IPsec uses cryptographic mechanisms, such as digital signatures and hash-based message authentication codes (HMACs), to verify the identity of the sender and the receiver, and to ensure that the data has not been modified during transmission. IPsec can also provide replay protection, which prevents an attacker from retransmitting old or duplicate packets. By combining SSL/TLS and IPsec, you can achieve a higher level of security and reliability for your cloud-based application.Reference:
