Which Applications? Which Servers? Which tools are susceptible to the Log4Shell; and more importantly, how confident are you that you found every instance of it?<\/p>\n\n\n\n<p>Using the SIFF configuration monitoring platform, you can quickly discover the location of the Log4j vulnerability by using a&nbsp; SIFF Service Definition (SD) to discover and identify the java processes that are using Apache Log4j, then leverage a SIFF Policy Definition (PD) to validate whether these instances are compliant or not&nbsp;(i.e. Log4j version &lt;= 2.14.1). Violations are flagged, users notified, and the platform can be configured to trigger automated remediation actions.<\/p>\n\n\n\n<p>To make this easy, we have created these SD\/PD and included them in the built-in SIFF community library. You simply have to activate these definitions and they will automatically examine any SIFF-managed devices for the Log4Shell vulnerability and notify you.<\/p>\n\n\n\n<p>If you are interested in learning more about using SIFF to ensure security and configuration compliance as well as how SIFF can help monitor configuration changes in your environment, <a href=\"https:\/\/siff.io\">learn more here.<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>I\u2019m sure by now you are well aware of the Log4j 2 vulnerability which is putting an unprecedented number of companies at risk.
