Question 796
Email is transmitted across the Internet using the Simple Mail Transport Protocol. SMTP does not encrypt email, leaving the information in the message vulnerable to being read by an unauthorized person. SMTP can upgrade a connection between two mail servers to use TLS. Email transmitted by SMTP over TLS is encrypted. What is the name of the command used by SMTP to transmit email over TLS?
Question 797
Robert, a professional hacker, is attempting to execute a fault injection attack on a target IoT device. In this process, he injects faults into the power supply that can be used for remote execution, also causing the skipping of key instructions. He also injects faults into the clock network used for delivering a synchronized signal across the chip.
Which of the following types of fault injection attack is performed by Robert in the above scenario?
Which of the following types of fault injection attack is performed by Robert in the above scenario?
Question 798
You are a cybersecurity trainee tasked with securing a small home network. The homeowner is concerned about potential "Wi-Fi eavesdropping," where unauthorized individuals could intercept the wireless communications. What would be the most effective first step to mitigate this risk, considering the simplicity and the residential nature of the network?
Question 799
A large corporate network is being subjected to repeated sniffing attacks. To increase security, the company's IT department decides to implement a combination of several security measures.
They permanently add the MAC address of the gateway to the ARP cache, switch to using IPv6 instead of IPv4, implement the use of encrypted sessions such as SSH instead of Telnet, and use Secure File Transfer Protocol instead of FTP. However, they are still faced with the threat of sniffing. Considering the countermeasures, what should be their next step to enhance network security?

Question 800
A U.S.-based online securities trading firm in New York is reviewing its transaction authentication process.
The security team confirms that each transaction is processed by first generating a hash of the transaction data. The hash value is then signed using the sender's private key.
During verification, the recipient uses the corresponding public key to validate the signature before approving the transaction. The system documentation specifies that the same algorithm supports encryption, digital signatures, and key exchange mechanisms within the organization's secure communications infrastructure.
Which encryption algorithm is being used in this implementation?
