Where I came from, where I am, and where am I going.

I started working in IT roughly 20 years ago. I was a student worker in the IT department of a local community college. While I had started my college career as a mechanical engineering major, I changed my major after speaking to one of the Computer Science professors. (I just so happen to have been assigned the Tech building for my work as a student worker).

Student workers were assigned very repetitive, somewhat menial work. To say the work we performed could have been done via a Shell script is no exaggeration. As the months went on I discovered I had aptitude for this type of work. What started as a problem/solution focused career of mechanical engineering type work changed to IT/Computer/Network problem solving.

I continued down this career path as desktop support at a handful of places of higher education. I watched my more senior coworkers in IT and the work they performed and I decided I wanted to go into the sysadmin networking field. I made that my goal.

I worked on my bachelor's degree (having completed my Associates at the previously mentioned community college) in Computer Science for a few years off and on while working. A life changing event while I was working in Atlanta had me move back home and transfer to the local university. I discovered they had a concentration in information security, and that became my choice. Though I had a hard time breaking into the information security field, when I finally did, I discovered yet again, I had a knack for it. It took me a bit over 3.5 years to finally become FTE in the information security field, and that was as a Cyber Security Engineer.

I have been a security engineer for over 2.5 years now. I enjoy the work, and have found a 'talent' for this type of work. I also realize that I have a lot to learn. This (as is any specialty within IT) requires constant learning and constant skill growth.

When asked by those much younger of what kind of job/career/work they should pursue, I tell them my hypothesis: “You can do what you love and you might learn to hate it; you can do what you hate and try to learn to love it (if it pays well); or you can do what you do well and make a career out of it.”

I chose the latter.

VMWare

In my day job I've been learning VMWare. In my night job (same as the day job, yay startups) I've been applying what I've learned. It's pretty spectacular. One of my coworkers has developed an awesome set of PowerCLI scripts to allow us to automate a CRAZY amount of our workload. I am overjoyed at every network I clone using them, so a huge thanks there.

VMWare on Google Cloud Platform is crazy powerful – I wish I could homelab some of this stuff. Today I stress-tested our Google Cloud – it performed amazingly well. I can't wait to share more about what we're doing, but I truly believe we're helping to revolutionize the cyber training and education industry.

Brief Thoughts on PKI and Certificates at Scale

This started as a reply to @davidseidl@mstdn.social and a thread about certificate expiration in a small organization (https://mstdn.social/@davidseidl/109638543580938963). He made some good points, but there's scaling issues for enterprises, as I outline and address below.

At the scale of a couple dozen certs, calendar alerts and individual/backup responsibility is okay. Once you get into hundreds and thousands of certs, you need to plan and automate as much as possible.

At enterprise scale, you're probably using certs for a number of tasks: * User Authentication * Device (server, service, container) Authentication * Data encryption in transit * Data encryption at rest

When you're working in an enterprise (1,000+ employees), maintaining the infrastructure necessary and helping developers understand how to accomplish their goals absolutely requires its own team. You're likely dealing with multiple certificate issuers (internal and external), along with ensuring all the moving parts of certificates (issuers, CMT, CRL/OCSP, and the servers/databases underpinning them) are working smoothly.

That also means thousands of certs on hundreds or thousands of devices, services, or containers. Unless you want your entire day to be consumed with manually updating certs (and maybe you like to do the boring stuff like that), automation is key.

A good Certificate Management Tool will do several things: * Find what certs are already out there through scanning * Manage certificate life-cycles * New certificate provisioning/installation * Renewing existing certificates * Maintaining certificate history * Centralized revocation in the event of a breach * Report what you have in appropriate granularity * Alert appropriate parties in cases where automation isn't yet available

Certificate Inventory: A CMT should be able to scan targets (though an IP range, an Active Directory OU, a list of URLs, et cetera) and find the certificates are either offered through various interfaces (like HTTPS) or stored on the device (like in the Windows CertMgr). The second option will require an account the scanner can use to authenticate to the account.

Certificate Life-Cycle Management: The bread and butter of installing, renewing, and revoking certificates. Maybe you want one cert for a service/application on a dozen servers. Maybe you don't want to have to manually deal with your public-facing .com cert every 60 days. Maybe you have a honeypot farm with a valid cert for $reasons that you want to be able to revoke with one button. That's the heavy lift a CMT provides. It can also maintain a history of previous certificates, so you have more pieces of the “when did this stop working” puzzle.

Reporting: Execs love pretty graphs, and some accountants love internal billing. Reporting from your CMT can make this literally automatic. Need to migrate from $OldCertIssuer to $NewCertIssuer, and Management wants some numbers on who's behind the curve? Security needs to audit all your externally-trusted certificates? Reporting!

Automation should be the target for the majority of your certificates' life, but sometimes automation just isn't available. Old line-of-business applications can be picky, and maybe you don't have the maturity yet for automation success. There are also some high-security edge cases where a manual process is required. Even if your CMT can't talk to the device (say because it's in a segregated network), the certs will still expire when the clock says they do. Or perhaps you have a third-party service that can't request certificates on their own. This is where monitoring and alerting can come into play. Monitoring and alerting on certificates before they expire can let you plan and communicate changes in a calm, orderly fashion instead of “oh gods the cert expired and we need to replace it five minutes ago!”.

An end-state goal is essentially the same as a well-oiled CI/CD pipeline (and in fact interacting with your CMT could be part of of that process). Review reports, alerts, and observability metrics. Let the computers handle the boring parts while your team handles the interesting choices of fitting use-cases and designing good, scaling solutions.

When you're using certificates for data-at-rest encryption, that data is only useful if you can decrypt it. We use our CMS to handle key escrow for our servers. There are specific additional security requirements around that, and we work with our internal security teams to ensure everything is handled properly.

Our CMS acts as a proxy/relay for most certificate use-cases in our environment. We've got a couple of distinct certificate authorities that do different things, but half the certs flow through our CMS. Sometimes that's “store and forward a CSR, return signed cert”, sometimes it's “Fill out a few fields, we'll take some default data, and handle everything behind the scenes”. The other half is just grabbing data from an Active Directory Microsoft Certificate Authority for reporting purposes.

Just because you're not ready for heavy automation doesn't mean you won't see value in a CMT/S. Step one of solving a problem is always identifying the problem. CMT/S will help with that too.

Good CMT/S will integrate with your existing toolsets. If you've got a smooth container deployment pipeline, ideally you can integrate your cert management with an API call or two to include standard, short-lived certs automatically.

The journey through automation (and away from waterfall development) is a long and winding road. How do you eat an elephant? One bite at a time. When you're looking to change and mature a culture, start with small wins. Build momentum. Get some easy-to-understand examples (especially within your own team) you can quickly (elevator-pitch style) demonstrate to others. Just as important is knowing when to say “This is a bigger challenge than anticipated, and we can leave it as a manual process for now.”

Layoff Advice From Experience

A ton of people have had a really bad time recently, with 200,000+ lay-offs over the past few months. I had a thread on birdsite last year with some good advice, so I thought I'd recap and generalize it here.

Things suck for a lot of folks. And they're going to suck for a little while.

I'm sorry.

Getting laid off a month before my 4th work anniversary felt almost exactly the same as finding out my long-term relationship was over because she was cheating on me. The same feelings of betrayal. The same sudden emptiness. The same massive, unplanned changes to life and routine.

Recognize that this is a sudden, drastic life change. Your routines are all destroyed. Your social circle may have just changed drastically. Don't be afraid to lean on your friends; they're there for you.

I don't know how long your runway is, but take some time to decompress. Whether that means tackling some projects you put off, or digging into your To-Be-Read pile, or binging on every season of Survivor is up to you.

Have some light conversations with contacts that you're in the market, but let the resume/application/interview prep wait a bit. It can wait, and will be better if your head is screwed on straight.

Interviewing is a specific skill-set, and you may benefit from waiting before jumping right to interviews. Again, this all depends on how long your runway is. Some limiting factors are immigration status, requiring heath insurance, or immediate monetary needs. All this advice is subject to change based on your specific circumstances. Review the current articles, gather your great stories, and start editing your anecdotes.

Take the swag and put it away. Don't throw it out, just tuck it out of sight. Maybe you'll come to a place where it reminds you of the good times you had. Maybe you'll decide to ceremonially burn it in the woods (responsibly). But it can wait until your head stops spinning.

Sometimes you lose a political game you didn't even realize what happening. Sometimes someone three levels above you loses a political game THEY may not have realized was happening. Neither one is good, but putting the pieces together helped me.

The same truth about dating (there's no “one”, you make the relationship through work) applies to companies too. Your last team may have been something special, but you can make a great place and team with good people anywhere. You can make a new special. YOU can make a new special.

I thought I had found a place I was going to spend the next 30 years at and retire from. Between internal politics and the 2017 tax code change, that rug was pulled out from under me. Since then, I've had two great positions where I'm doing even better work. But the trust of just standing on a rug is gone. Now I'm always read to jump.

Be okay with sitting in the weird quiet for a bit. Then dust yourself off and make a new special.

I signed up for this without thinking through what I'm getting. Shiny! Squirrel!

I'm testing to see if this is Markdown savvy.

I have a Wordpress site, but it's not well used.

This isn't as fancy-schmancy as Wordpress, so that may be what I need. Less distractions.

It's also adjacent to my Mastodon account, so maybe it'll be easy.

Time will tell.

Mattermost's mobile apps would get a major overhaul, for both the Android and iOS worlds. The new versions have been rolled out since this week.

Mattermost can be used as an #OpenSource alternative to MS Teams. The details...

Today I had a run-in with some people from a cybersecurity Bootcamp (you can read my LinkedIn for further details). Suffice it to say, I've had several people join VetSec who feel like they were taken advantage of by some of these bootcamps. BLUF: Buyer beware. Many of these will not actually help you get into the industry. This one, in particular, offers no certifications (they give you vouchers if you want to go above and beyond on your own), and has almost no criteria for graduation other than showing up.

It's extremely frustrating to run a 501c3 that is doing real good work out there and struggle to find funding, meanwhile, this bootcamp gets 18k a head as long as they find meaningful employment post-graduation. This is an organization running a program they call “Certified Penetration Tester”, but they get 18k if the person lands a helpdesk role following completion of the program.

I'm sorry, but this is complete and utter bullshit. /rantover

Hacking Your(My) Health

Anyways, moving on.

I've been participating in the HACKS v1.0 program from Ben Canning. If you're not familiar with Ben, he's a trainer and awesome dude from Hack Your Health and runs his own training company. He focuses on lifestyle changes surrounding nutrition and working out. I signed up for his HACKS group program in November, and I have to say, I struggled hard with it over the holidays. Combatting 39 years of “clear your plate, don't waste food” has been a struggle. Figuring out how to eat as much protein as Ben prescribes has also been a trick. Any time I've broken with a routine (travel, etc.) I've fallen off the proverbial bandwagon.

As I'm winding down my Navy time now, I'm glad to be able to settle into a little more of a routine and focus on my health. I'm dedicated to writing about this journey here as well.

Start date: 11/1/2022. Starting weight: 258 Current date: 1/19/2023, Current weight: 246

Course Work

Finally, I'm working on writing a video-based course that will teach some foundational IT stuff. I can't say more until it releases, but it's been a journey already, learning the presets for OBS, buying a 4k webcam a streamdeck, and forcing me to clean up my office. My goal is to record my first couple of videos tomorrow and get them over to the publisher, and I'm super excited to get started.

Anyways, thanks for tuning in, everyone. I'll continue to share my personal and professional struggles and takes.

Cheers!
