Security Advisories to Take Action On (for June 2022)
Intra-Splunk Transport Layer Security (TLS) is a best practice to implement for any application that communicates over the public network. The three available updates in Splunk Enterprise 9.0 enable you to configure TLS at the right time for your business (ISVC-2022-0602, SVD-2022-0603, SVD-2022-0606).
Securing forwarders and deployment servers is important to the security of your overall Splunk deployment. These three updates enable you to apply stronger security at the forwarder (SVD-2022-0605, SVD-2022-0607) as well as between the deployment server and forwarder (SVD-2022-0608).
Securing the app model is important to the security of your overall Splunk deployment as apps are considered part of your trust boundary. This update enables you to apply stronger security between the application and your Splunk system (SVD-2022-0601).
Splunk search processing language (SPL) is powerful, with great power comes great responsibility. This update makes it possible to more fully safeguard against edge case scenarios for data exfiltration and arbitrary code execution using SPL (SVD-2022-0604).
