7MS #464: Interview with Christopher Fielder of Arctic Wolf

Hey, hope you're having a great week! The last few weeks have had somewhat of a homecoming and home cleaning theme. To continue that train of thought, over the last few days I've gotten heavy into cleaning up my cloud clutter - cloud services, email, file sharing, etc. - in an effort to be more secure and have a reduced digital footprint. Today's tips include: Double-check that any device you have that supports full-disk encryption has it enabled On all your machines, clean up old straggler artifacts in C:, desktop folder, downloads folder, etc. Use the nifty built in tools for Windows 10 to free up even more disk space (I just learned about this one recently - Windirstat and Treesizefree were my go-tos for years) Got old PCs sitting around you're not using? Nuke 'em with DBAN. Go into your password vault and clean out creds for services you don't use anymore (especially for old client projects!) Purge your file share services (Dropbox, OneDrive, etc. on a regular basis), and/or bring older archives over to cold (on-site) encrypted storage Review your "bottleneck" accounts (key email accounts, for example) and review the devices/services linked to them - clean up and purge regularly Handling password hashes? Here's one way to setup an encrypted partition for them You can clean old email from Gmail quickly using some simple searches. You can also use Google Takeout to download offline copies of mail and then browse them later with Thunderbird

Hi again! It's sort of fun to release two episodes in one week for a change. If you missed part 1 on our ioT security series, check it out here. Today we dive into some free/cheap monitoring solutions you can use to keep tabs on your ioT network (or any network, really): Nagios - it's old school but gets the job done. This article helped me get it going on an RPi. SolarWinds IP monitor - it was quick and easy to get up and running, but the 40 monitors you're allotted get burned up pretty quick if you have a decent number of devices to monitor PRTG - this is the winner in my book. It has a generous amount of monitors, quick/easy install, and a native mobile app!

WE'RE HOME! After almost a year after our fire, we're back, baby! This episode is somewhat of a homecoming that dovetails into an episode about ioT security. I've basically done a 180 degree spin on ioT stuff. I now love the coolness and convenience of these things while simultaneously being terrified of the security risks. Is there a happy balance somewhere between the two? Maybe. Today we dive into ioT security, specifically: Setting up a ioT dedicated wireless network Quarantining it so it can only talk to the Internet Poking holes in the firewall to allow ioT DNS requests to be captured Scanning your ioT for services and potential default/weak cred use

Yay! It's time for another tale of pentest pwnage! Highlights include: Making sure you take multiple rounds of "dumps" to get all the delicious local admin creds. Why lsassy is my new best friend. I gave a try to using a Ubuntu box instead of Kali as my attacking system for this test. I had pretty good results.

Today we're talking business! We've got some exciting news and updates to share with you since we last did a "crying" episode last fall: 7MS hired a VP of sales and marketing: Clyde Cooper! We've added some new tools to our tools/services gist: Having a true sales force for the first time has prompted us to invest in Salesforce. There are a few gotchas with signing up for a Salesforce trial and then migrating to a paid plan (discussed more in today's episode) We're trying to "eat our own dog food" and part of that includes good inventory management. For that we've started to play with Rumble and reaaaaaaaaaaalllly like it Recording an "about us" video with a production company is exciting, stressful and awkward Today I met the guy who wins the Internet (or at least LinkedIn) - he sent me a personalized video with an idea I'm definitely going to steal for future marketing initiatives For really no reason at all, I sing for you a bit in this episode On that note, I absolutely love this song. I feel like it's my family's theme song for the last year.

Today we're thrilled to have our friend and PlexTrac CEO Dan DeCloss back to the program! (P.S. PlexTrac is launching runbooks as a feature - and you should definitely check out PlexTrac's upcoming Webinar about runbooks on September 9!). We also did a PlexTrac 101 Webinar with them recently! You may remember Dan from such podcasts as this one when we first talked to him in 2019. Dan and I have a lot in common in that we both started security companies about the same time, so I had a lot of questions for Dan around how business has been going since we last talked on the podcast. Today our topics/questions include: What are the (good) warning signs that a passion project you have could be a viable business? Why "having all the jobs there has ever been" is a great way to figure out it's time to start your own business :-) At what point does a side project have to become what you do for your day job? How do you safely prepare to quit a comfortable corporate life to life as a small biz owner? Do you go 100% on faith? Do you save your $ for a year so you can "float" your business for a while? Some combination of the two? How important is it to have the support of your friends/family when starting a new biz? Once you start a biz what are the best/worst things about wearing all the hats (engineering, sales, marketing, accounting, HR, etc.)? When is it time to hire additional resources or raise additional money to support your growing business? What marketing efforts are fruitful for a new security biz to spend time/money on? How do you decide what bells/whistles to add to PlexTrac? Follow your own roadmap? Let the customers drive your direction? Some combo of both? What new bells and whistles are coming to PlexTrac in the Webinar on September 9?! (Spoiler alert: RUNBOOKS!)
