312-38 ECCouncil Exam Lab Questions

 In MacOS, security-related logs are typically stored in the /private/var/log directory. This location is used to store various system logs, including authentication attempts and other security events. The secure.log file within this directory is particularly relevant for tracking security incidents, as it records authentication attempts and other security-related events. It’s important for network defenders like Rosa to be familiar with these log locations to monitor and respond to potential security issues on the systems they manage12.

References: The information provided here is consistent with standard MacOS logging practices and the EC-Council’s Certified Network Defender (CND) curriculum, which includes understanding the security mechanisms of different operating systems and how to locate and interpret system logs12. For more detailed information, please refer to the official CND study materials and documents provided by the EC-Council.

Single-sign-on (SSO) is an authentication process that allows a user to access multiple applications with one set of login credentials. This is particularly useful in an environment where employees need to access a variety of systems and applications, as it simplifies the user experience and reduces the need for multiple passwords. SSO is designed to alleviate the administrative burden of managing multiple sets of credentials and toimprove security by reducing the likelihood of password fatigue, which can lead to weak password practices.

References: The concept of SSO is covered in the Certified Network Defender (CND) course, which includes understanding various types of authentication methods. SSO is mentioned as a type of authentication that allows users to be authenticated once and gain access to multiple systems without being prompted to log in again for each system1.

The integrity check mechanism used by WPA2 to provide security against replay attacks is the Cipher Block Chaining Message Authentication Code (CBC-MAC). This mechanism is part of the protocol suite that ensures data integrity and authenticity by using a combination of cipher block chaining (CBC) and message authentication code (MAC) to produce a secure and unique code for each data packet.

References: This information is consistent with the security protocols outlined in WPA2 standards, which specify the use of CBC-MAC for integrity checks12.
