Question

Based on their own experiences, how often do they feel they would check these files, and how vigilant do they think they would be about the process? Have them outline some of the reasons why an administrator might tend to ignore these files.

2. Discuss there experiences with the creation of user and group accounts in other OSs such as Windows 10 or Windows Server 2019. What do they feel are some of the advantages and disadvantages of the various utilities provided for user management on these systems, as well as the way that user information is stored?

Answer 1

In the Linux family of operating systems various log files are stored in var/log directory.

These log files store footprints of various actions of user and system.

There are many directories in which these log files are stored.

to view log files in cent os with root user access change your directory as

# cd var/log

# ls

var/log/messeges: This directory shows general messeges of system.

var/log/auth.log: This file shows authentication logs.

var/log/kern : This directory shows logs of kernel

var/log/httpd: This directory shows all files related to apache web server like failed connection, file not found on the server, unauthorised access, script execution related messages.

var/log/yum.log : This file shows yum command related logs.

System administrator usually checks apache server related logs so admin can make changes according to errors in apache web server to ensure web server runs continuously and dont have downtime.

System administrator has to aware about critical systems logs to ensure os is healthy.

There are bunch of logs that only shows excution of programs and system processes so, admin has to ignore these log files.

In windows users are created through computer management section.

In this section there is menu Local users and groups, when we click this menu there is window new user where we have to put username and password and new use is being created.

Because of GUI user creation process is very easy in windows 10, also granting rights to user is also very easy, in the Linux os grantig various rights to user is difficult process.

In linux accessing user account is very easy with perfect access rights, in windows many conclifcts may happen with user access grant with rights. linux uses public and private keys to access account, in windows users information is stored and encrypted in system.
