Part of your job is to investigate security issues to help keep the system secure. You recently discovered some potential security issues that involve login attempts and employee machines.</p> <p>Your task is to examine the organization’s data in their employees and log_in_attempts tables. You’ll need to use SQL filters to retrieve records from different datasets and investigate the potential security issues.</p> https://kazuf3.nicheapplab.com/posts/apply-filters-to-sql-queries/ Tue, 18 Jul 2023 18:39:54 -0700 https://kazuf3.nicheapplab.com/posts/apply-filters-to-sql-queries/ <ul> <li><a href="https://kazuf3.nicheapplab.com/posts/sql-queries/">Back to SQL Queries</a></li> </ul> <h2 id="project-description">Project description</h2> <p>This project is for investigating security issues to help keep the system secure. Based on findings that some potential security issues involve login attempts and employee machines. We use SQL filters to retrieve records from different datasets and investigate potential security issues.</p> <h2 id="retrieve-after-hours-failed-login-attempts">Retrieve after hours failed login attempts</h2> <p>In order to list all after-hours failed logins, which are suspicious in this case, we performed a SQL query as follows. Since hour regular hour ends at 18:00:00, we set the condition accordingly. <img alt="image1" loading="lazy" src="https://kazuf3.nicheapplab.com/posts/apply-filters-to-sql-queries/images/image1.png"></p>
