IT Pro Tuesday #160

Get this in your inbox each week.

Welcome back to IT Pro Tuesday!

Did you know that Microsoft 365 allows ransomware threats, phishing messages and spam to enter your users’ mailboxes? Although Microsoft provides email threat protection on M365, it only offers a basic level of security that is not enough. To prevent your users from introducing ransomware and other threats, you still need an additional layer of email security.

This week, we’re proud to announce a new, free tool we developed so sysadmins can find out how many threats make it through to your organization on M365 and proactively prevent users from being tricked. It’s called 365 Threat Monitor, and we’re excited to share it with all of you in the IT Pro Tuesday community! 

365 Threat Monitor is a forever-free mobile app that detects any threats that breach your Microsoft 365 security. Once it identifies a malicious email, it sends a phone alert so you can instantly delete it with just one click and prevent any damage. The app is developed by Hornetsecurity, which provides premium email security services to 40,000+ customers worldwide.
To celebrate the launch, Hornetsecurity—the people behind IT Pro Tuesday—are offering the forever-free version to the first 10,000 M365 IT admins who download the app.

Setup takes seconds – Learn more and download the app here.

We're also marking the occasion with a categorized MEGA LIST of all the items we've featured over the past 6 months. Enjoy!

Security Content Automation Protocol (SCAP) is a compliance checker tool for evaluating the hardening of your machines. It used to be available only for DoD, government or contractor use but was recently released to the public by DISA. This automated program scans a machine (locally or remotely) to determine security posture based on Security Technical Implementation Guidelines (STIGs)—the checklists that identify what constitutes an open or closed vulnerability and how to remediate it. swatlord notes that "STIGs (the rules SCC derives from) are what the DoD and DISA think should be set in order to harden machines... some of the items they hit against are no longer standard practice (eg expiring passwords). This is why it’s important to not just blindly remediate open STIG items without understanding how it impacts your environment."

gProfiler is an easy-to-use, open-source tool that produces a unified visualization of what your CPU is working on, displaying stack traces of your processes across native programs, Java and Python runtimes and kernel routines.

Apcupsd is designed for power management and control of most of APC’s UPS models on Unix and Windows machines. During a power failure, it notifies users that a shutdown may occur. If power is not restored, a system shutdown will follow when the battery is exhausted, a timeout (seconds) expires, or runtime expires based on internal APC calculations determined by power consumption rates.  Apcupsd works with most of the Smart-UPS models and most simple signaling models such as Back-UPS and BackUPS-Office. gerdesj likes that it "has a mini web interface that can show multiple UPS's details."

Pping measures the roundtrip delay application that packets experience relative to any capture point on the connection's path, using the naturally occurring reflected signal that can be obtained when the timestamp option is used in a TCP connection. These delays are collected per TCP connection with outbound packets providing the signal and inbound packets the reflection, and Pping measures the delay of two different round-trips from the monitored packets. jiannone suggests it as a "more intriguing option [for service assurance monitoring] ... It's an edgier solution but not synthetic in any way. The philosophy is spot on. The execution requires a lot of effort though."

A great idea for labelling cables, compliments of reddwombat: "Use wrap mode, but not directly on cable. Put a large diameter plastic straw over the cable first. On fiber, it gives you more space to type… also allows spinning to read it, and labels tend to stay stuck."

GoogleDrummer adds, "You can still do this with premade, just run a cut up the straw, place it around the cable, then wrap the label around the cut closing it back up." 

And gregarious119 shares another idea: "Something we have found to make installs/troubleshooting/organization easier is that we have our patch cables color coded to length: 5’-White, 7’-Green, 10’-Blue, 14’-Gray, 25’-Black, 50’-White, Custom-Purple, Orange-Non-data (Video/HDMI converters, etc), Red-Crossover, Yellow-Datacenter. It's not a game-changer, but it really makes identification quick and easy when you're in a pinch and need to install something quickly."

moltari adds, “We color code by what they do: black-Security, Purple-WAP, Yellow-Corp Data, Blue-Phone, etc."


We all hate accidentally sending unfinished emails, especially on sensitive topics, but it happens nonetheless. To eradicate the risk from your life, hasthisusernamegone suggests, "[D]on't compose it in your email client at all. All my ‘this is official, don't get this wrong’ emails are composed in a basic text editor (often Notepad), then copied and pasted over to Outlook when I'm happy with them. Then it gets another proof-read and a chance for the spell-check to do it's thing and only then does it get sent. That way I can't accidentally send a half-finished email to the board or whoever."


A great idea, kindly shared by gartral:

I automated the clock cards (mag strip badges) re-encoding the strips that *always* fail between 4-6 weeks of daily use. Cards have a barcode that identifies the person for certain systems. Cards have mag strips that identifies them for the doors… Took a tedious job Security absolutely despised doing and turned it into a self-help kiosk.

Workflow went from: Get buzzed in by security > have chat with guard > wait 5+ minutes for guard to fumble around… < repeat last step 1x > Get freshly written card

to: Get buzzed in > Shrug at Security > Scan badge > Enter AD Password > Swipe Card > Continue your day.


Some sage advice from technicalityNDBO for anyone thinking they should probably feel more 'expert' in the field by now:

"IT is like a knowledge treadmill. You're always learning new technology and forgetting obsolete. Other skilled trades allow for spending 100% of your effort into getting better and better. In IT, you have to invest a non-significant amount of effort into just not getting worse."


Building on our recent tip about logging terminal sessions, ahelsby adds:

[W]hen logging your terminal sessions – make sure you don’t log your password to those plain text log files! You can also log all of your powershell work too – I use the following to save to a temporary directory and update the window title with the filename

$transcriptlog = "c:\temp\powershelllogs\" + $env:username + (get-date -uformat "%y%m%d-%H%M%S"") + ".txt"

catch [System.InvalidOperationException]{}
start-transcript $transcriptlog
$host.ui.rawui.WindowTitle = $transcriptlog

If using powershell, install the psreadline module and then add the following to your $profile so your history does not contain any commands with the secret words in it.

Set-PSReadLineOption -AddToHistoryHandler {
    $sensitive = "password|asplaintext|token|key|secret|credential"
    return ($line -notmatch $sensitive)


A trick for rack mounting a heavy switch from docmn612:

"Screw a rack screw into the hole right below the one the device is going in, and rest the ears on those. The device should stay put while you lift one side up at a time and screw in the bottom screw."


Time-savers offered by shipsass:

  • Is user in any admin groups: whoami /groups | find "Admin"
  • Reboot in 10 minutes: shutdown -r -t 600
  • Generate battery report: powercfg /batteryreport
  • Generate wifi report: netsh wlan show wlanreport
  • Force an app to stop running: taskkill /f /im notepad.exe
    ...on a remote computer: taskkill /s computername /im notepad.exe
  • Windows update stuck shutting down trustedinstaller and you need to force reboot (run from another networked pc): sc \\computername queryex trustedinstaller
    Taskkill /s computername /f /im trustedinstaller.exe

An engineering suggestion from PeakSufficient2839:

"Set up your favorite terminal program to log EVERY session. Make a folder, put it somewhere you'll remember, and log all your sessions into it. I called mine ‘Sessions’ and put it on my desktop. This works wonderfully for tracking config changes, remembering CLI commands, ‘show’ commands from weeks ago etc. I've come back to files over and over again, finding relevant info from previous events. Totally worth it."
