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

WPA3 encryption is the type of wireless encryption used by the security solution employed by Matias in the above scenario. WPA3 encryption is the latest and most secure version of Wi-FiProtected Access, a protocol that provides authentication and encryption for wireless networks. WPA3 encryption uses 256-bit Galois/Counter Mode Protocol (GCMP-256) to maintain the authenticity and confidentiality of data. WPA3 encryption also provides enhanced protection against offline dictionary attacks, forward secrecy, and secure public Wi-Fi access . WPA2 encryption is the previous version of Wi-Fi Protected Access, which uses Advanced Encryption Standard (AES) or Temporal Key Integrity Protocol (TKIP) for data encryption. WEP encryption is an outdated and insecure version of Wi-Fi security, which uses RC4 stream cipher for data encryption. WPA encryption is an intermediate version of Wi-Fi security, which uses TKIP for data encryption.

 Masking is the technique that Andre employed in the above scenario. Masking is a deidentification technique that can replace the critical information in database fields with special characters such as asterisks (*) and hashes (#). Masking can help protect sensitive data from unauthorized access or disclosure, while preserving the format and structure of the original data . Tokenization is a deidentification technique that can replace the critical information in database fields with random tokens that have no meaning or relation to the original data. Hashing is a deidentification technique that can transform the critical information in database fields into fixed-length strings using a mathematical function. Bucketing is a deidentification technique that can group the critical information in database fields into ranges or categories based on certain criteria.

PCI-DSS requirement no 5.3 is the PCI-DSS requirement that is demonstrated in this scenario. PCI-DSS (Payment Card Industry Data Security Standard) is a set of standards that applies to entities that store, process, or transmit payment card information, such as merchants, service providers, or payment processors. PCI-DSS requires them to protect cardholder data from unauthorized access, use, or disclosure. PCI-DSS consists of 12 requirements that are grouped into six categories: build and maintain a secure network and systems, protect cardholder data, maintain a vulnerability management program, implement strong access control measures, regularly monitor and test networks, and maintain an information security policy. PCI-DSS requirement no 5.3 is part of the category “maintain a vulnerability management program” and states that antivirus mechanisms must be actively running and cannot be disabled or altered by users, unless specifically authorized by management on a case-by-case basis for a limited time period. In the scenario, Ayden works from home on his company’s laptop. During working hours, he received an antivirus software update notification on his laptop. Ayden clicked on the update button; however, the system restricted the update and displayed a message stating that the update could only be performed by authorized personnel. This means that his company’s laptop has an antivirus mechanism that is actively running and cannot be disabled or altered by users, which demonstrates PCI-DSS requirement no 5.3.
