With osquery, you can not only gather the inventory, but do it automatically, and leverage the data to improve the security of your environment.By Sharvil Shah, senior software engineer Other standards, like HIPAA, require risk assessments to be performed, which is facilitated by the existence of a good inventory of hardware and software. Requirement 2.4 states that software on systems in scope for PCI DSS must be inventoried and kept up to date. Software inventory is the second of the CIS Critical Controls, but it's also an important part of PCI DSS. This allows updates to be enforced, rather than letting end-users deal with the trouble of updates on their own.

By having the full picture for all machines in your environment, you will be able to better understand the attack surface of your systems, and see if some specific packages could benefit from being managed by IT. It is useful to detect unauthorized software, in more locked-down environments, but it can also be useful to hunt down known vulnerable versions of software. Benefits and compliance requirementsīeing able to track installed software is extremely important. The following query extracts valuable information about Firefox add-ons: SELECT username, name, identifier, version, creator, active FROM users JOIN firefox_addons USING (uid) Īnother way to join tables, demonstrated here with the chrome_extensions table: SELECT * FROM chrome_extensions WHERE chrome_extensions.uid IN (SELECT uid FROM users) īy using all of these tables-by configuring queries for them in your query packs that get executed regularly-you will have a complete picture of the software installed on your systems, including browser extensions and software installed by third-party package managers. These tables need to be joined to the users table, so you can know which user profile has the add-on installed. You will find this common with browser-related tables, such as the firefox_addons table. Some of these tables report per-user data.

Next time you hear about a critical vulnerability on a Chrome extension, or you notice malware targeting a specific version of a PDF reader in your environment, you’ll be able to instantly see which assets are at risk. Once you know the tables osquery has for software inventory, you will be able to automate the collection of that data, so it is always available to you. getting a thorough understanding of what is installed requires looking at many different sources of information. Regular applications, app stores, browser extensions, third-party package managers. Software inventory can be easier said than done, as there are more and more sources for software on our workstations and servers. There’s a good reason software inventory is No. Gathering software inventory is an important part of security and systems management.
