212-82 Exam Dumps : Certified Cybersecurity Technician (CCT)

The IP address of the attacker is 10.10.1.16. This can be verified by analyzing the Windows.events.evtx file using a tool such as Event Viewer or Log Parser. The file contains several Audit Failure logs with event ID 4625, which indicate failed logon attempts to the system. The logs show that the source network address of the failed logon attempts is 10.10.1.16, which is the IP address of the attacker3. The screenshot below shows an example of viewing one of the logs using Event Viewer4: References: Audit Failure Log, [Windows.events.evtx], [Screenshot of Event Viewer showing Audit Failure log]

Exception handling is a secure application design principle that states that the application should handle errors and exceptions gracefully and securely, without exposing sensitive information or compromising the system’s functionality. Exception handling can help prevent attackers from exploiting errors or exceptions to gain access to data or resources or cause denial-of-service attacks. In the scenario, Miguel identified a flaw in the end-point communication that can disclose the target application’s data, which means that the application did not meet the exception handling principle.

WEP is the type of wireless encryption employed by Charlie in the above scenario. Wireless encryption is a technique that involves encoding or scrambling the data transmitted over a wireless network to prevent unauthorized access or interception. Wireless encryption can use various algorithms or protocols to encrypt and decrypt the data, such as WEP, WPA, WPA2, etc. WEP (Wired Equivalent Privacy) is a type of wireless encryption that uses the RC4 algorithm to encrypt information in the data link layer . WEP can be used to provide basic security and privacy for wireless networks, but it can also be easily cracked or compromised by various attacks . In the scenario, Charlie, a security professional in an organization, noticed unauthorized access and eavesdropping on the WLAN (Wireless Local Area Network). To thwart such attempts, Charlie employed an encryption mechanism that used the RC4 algorithm to encrypt information in the data link layer. This means that he employed WEP for this purpose. TKIP (Temporal Key Integrity Protocol) is a type of wireless encryption that uses the RC4 algorithm to encrypt information in the data link layer with dynamic keys . TKIP can be used to provide enhanced security and compatibility for wireless networks, but it can also be vulnerable to certain attacks . AES (Advanced Encryption Standard) is a type of wireless encryption that uses the Rijndael algorithm to encrypt information in the data link layer with fixed keys . AES can be used to provide strong security and performance for wireless networks, but it can also require more processing power and resources . CCMP (Counter Mode with Cipher Block Chaining Message Authentication CodeProtocol) is a type of wireless encryption that uses the AES algorithm to encrypt information in the data link layer with dynamic keys . CCMP can be used to provide robust security and reliability for wireless networks, but it can also require more processing power and resources
