Using Linux Commands to Manage File Permissions and SQL Filters in Queries

In this project I worked with the research team of a large organization and my job was to ensure that users on this team are authorized with the appropriate permissions.

I examined existing permissions on the file system to determine if the permissions matched the authorization that should be given. If they didn't match, I modified the permissions to authorize the appropriate users and remove any unauthorized access.

I was also tasked to use SQL filters to retrieve records from different datasets and investigate potential security issues that involved login attempts and employee devices.
