Audit CentOS logs using EventLog Analyzer

CentOS is a popular Linux-based operating system used in many enterprises. All CentOS systems store a complete record of the events that took place in them as syslogs.

To ensure network security, network administrators need to analyze logs from different sources, including CentOS machines. Manually collecting and analyzing this huge volume of logs is just not possible. What you need is a log management tool that can quickly collect logs from multiple sources, process those logs efficiently, and provide you with meaningful insights into network events.

CentOS audit reports in EventLog Analyzer

EventLog Analyzer is a log management tool that collects, analyzes, and reports on log data from CentOS devices. This solution comes with over 1,500 out-of-the-box reports, of which a considerable number are dedicated to CentOS devices.

CentOS logon and logoff reports

These reports contain information on all the logons and logoffs that have happened on CentOS devices. These include separate reports for different logon methods, such as SU, SSH, and FTP.

CentOS failed logon reports

These list all the failed logons and the users who have the highest number of failed authentications. This information can be used to blacklist suspicious user accounts.

CentOS user account management

This includes a complete list of all the users and groups which have been added, removed, or deleted. Critical data points, such as failed password changes, are also available.

CentOS removable device auditing

This includes reports on all the removable devices plugged in and out of the CentOS devices in your network.

CentOS mail server reports

These reports contain:

• Email server usage patterns
• Trends of sent and received emails
• Users and devices sending and receiving the highest number of emails
• Frequently encountered errors, such as unavailable mailboxes, insufficient storage, and bad sequences of commands

CentOS FTP server reports

These reports provide a comprehensive account of all the files that were uploaded and downloaded from CentOS-based FTP servers. Users who performed the most operations on the FTP servers can also be identified.

CentOS severity reports

These reports classify events in CentOS devices based on their severity. These events are classified as emergency, alert, critical, error, warning, and more.

CentOS critical reports

These reports feature the critical events identified in CentOS devices. Events are segregated based on the event ID generated or the device in which they were spotted.
