Locking Down Your Accounts: How to Keep the Keys to Your Kingdom Safe Cerberus Sentinel Blog

Some of you may work in highly technical roles, with a slew of devices, complex systems to manage, and specialized software. Others of us may keep it simple–maybe just a laptop and O365. Either way, we all intersect at one point. Nearly all of us have a Google account and/or a Microsoft account. Gmail, Google’s email platform, is that magical place you can send all of your unwanted advertisements and solicitations when signing up for newsletters. It’s the account you use to sign up for your kids’ team updates or daily school notifications. Further, you may take advantage of other Google platforms (like the calendar), all of which are managed under the same Google login. Google is free, convenient, and allows you to keep your personal messages separate from work accounts. In fact, you probably set that account up right about the time you quit using Yahoo and have probably given its management an equal amount of thought. When you’re at work, though, you’re logging into Microsoft products, almost inevitably. In fact, your phone may sync with your Microsoft account, allowing you to edit a document while on the train, commuting to work, or check out a spreadsheet on the fly while eating lunch with friends. The widespread user base of these two account types, as well as the device and account interconnectivity most of use employ for our daily lives, point to why they are the two most frequently hacked account types. If you are a threat actor, you know how to leverage access to these accounts to do a lot–a LOT–of damage.

In our last blog for this series, TRUE Security Consultant, Steven Anderson, detailed the importance of personal security as paramount in working into professional security. Simply put, if threat actors can get into your personal account, it’s very simple for them to pivot into your work accounts, either through spyware, information they glean while reading your emails, or even something as simple as a reused password. In this installment, Anderson walks us through, step-by-step, how to lock down your Google and Microsoft accounts. Be safe out there, kids, so you can avoid that sinking feeling of discovering a breach.
