This power gives security analysts the power to make hard decisions, faster and with confidence. You can expose valuable connections within an attacker’s infrastructure - including co-occurrences, related domains, geolocation, categorization, and reputation scores. What does this mean? It’s sort of like having eyes in the back of your head… you can see the connections you’ve been missing during investigations. With the new Cisco Umbrella Investigate Add-on, you can automatically enrich security events in a Splunk security environment with threat intelligence about the domains, IPs, and file hashes used in attacks. ![]() Most recently Cisco has focused on new points of integration between Umbrella Investigate and Splunk, making it quicker and easier to access Investigate’s rich context to speed up decisions during investigations. Together, Splunk and Cisco are changing the way organizations approach and respond to threats. Splunk and Cisco have collaborated on several dozen free Splunk apps and add-ons that provide ready to use functions for Cisco’s industry-leading security, networking, wireless, data center, and collaboration portfolios. We need actionable threat intelligence that can help us make better decisions when identifying and remediating attack campaigns.Ĭisco is proud to be partnering with Splunk, the market leader in analyzing machine data to deliver operational intelligence. But the more data we collect, the more we need to analyze… and most times we don’t have the luxury of time to weed through it. But that leaves users more vulnerable to threats, and you also have to figure out how to control sensitive data, apps, and infrastructure in the cloud.Īs security professionals, we deploy more and more security tools in hopes of keeping everything (data, users, devices) locked down and protected. VPN is no longer necessary to get work done, they use Software-as-a-Service (SaaS) apps. So how do you see what’s happening on the internet, beyond your perimeter? Isn’t that the question security professionals have been struggling with as the world becomes more mobile? Your employees connect to the internet from many different locations and devices. Use at your own risk.The following is a guest post by Rachel Ackerly, product marketing manager, Cisco Umbrella.ĭo you have eyes in the back of your head? (Unless you’re my mother, there is a good chance you don’t.) Many security products claim to provide visibility into what’s happening on your network, but how many actually deliver on that promise? Syncing lookups between your development and production or Enterprise Security and Ad-hoc search heads is no longer a problem! Feel free to install the SA or simply copy and paste the SPL from the macro as needed. This output can then be piped to the outputlookup command and written to a local file.Īutomating this transfer is now as simple as creating a scheduled search. I created a macro with some SPL magic that retrieves the lookup and reformats the contents into a table. If you run this search, you will notice the contents of the lookup are merged into a single value. | rest splunk_server=sh1 /services/search/jobs/export search="| inputlookup demo_assets.csv" output_mode=csv | fields value Using the following search, I could retrieve the contents of the lookup file named “demo_assets.csv” from sh1: I then added SH1 as a search peer to SH2. I setup two search heads in my lab environment, sh1 with a “demo_assets.csv” lookup and sh2 without the lookup. I then realized I could do the same thing using rest command on a search head. I knew I could run a curl command from the operating system, execute any search, and retrieve the contents of a lookup using Splunk’s robust REST API. I then knew the solution, I needed to figure out a way to run the inputlookup command remotely. I began looking at existing REST endpoints and realized there was not one that would retrieve the contents of a lookup file. I was hoping the inputlookup command allowed for the use of splunk_server, but it didn’t. Knowing that Splunk can search a specific search peer using the splunk_server parameter, I added the source search head to the destination search head. However, I wanted to use pure SPL so this solution could be completely portable, and usable without installing additional apps. Since Splunk is a very open platform, I knew this could be accomplished using a custom REST endpoint. I was working with a customer a couple weeks ago who has several search heads and wanted a way to sync lookup files without relying on third party tools such as rsync. If you have seen my previous post “ Upgrading Linux Forwarders Using the Deployment Server”, you can see that I love figuring out how to do unconventional tasks using Splunk. ![]()
