EVE-NG Community Edition is the first clientless multivendor network-emulation software that can be run in a completely isolated environment so that network and security professionals can create virtual proof of concepts, solutions and training environments. The limitations [of the community version vs. pro] are ok for me. The only thing you need to think about is the connections/cables, but you get used to doing that at the beginning of the lab when everything is still shut down. Otherwise, I have the client side pack for Wireshark, which works great.
AS-Stats is a simple tool that uses Perl scripts to generate per-AS traffic graphs for one or more routers based on the NetFlow/sFlow records.

SSL Security Test is an online tool for testing the security of your web and email server SSL, SSL certificate and PCI DSS, HIPAA & NIST. Explains, “It is a scanner tool that runs externally and from a webbrowser … It is free, but to get printable reports, or to save results, it costs money. I recommend when using it that you check “hide from global results” as if you do not, your IP and vulnerabilities will become public info. This is a great assessment tool, and is basically just an external server that runs sslscan (Linux command line) on all 65k ports to see if anything is open. Will also tell you if your edge router has old encryption and such.”
OCS Inventory is an asset-management solution that discovers the soft and hard composition of each machine and server as well as the active elements on your network. A web console allows you to view inventory results and the detected network hardware and to create deployment packages.
EasyJob helps you organize and execute all your PowerShell and BAT scripts from a single interface. Its author, akshin1995, explains: “As a sysadmin, I use many PowerShell scripts on a daily basis.

It does have the M365 Business plans split into two separate locations—Biz Premium with M365, the others under O365. Bear in mind that the original predates the rebranding of O365 plans.

NIST Password Guidelines and Best Practices are considered by experts to be the gold standard for password security because of how well researched, vetted and applicable they are for the private sector. Find out if your organization is using password practices that are outdated or even counterproductive, so you can keep your data safe. Who adds, “Honestly, it worries me the amount of IT pros glossing over these requirements.”
Some helpful advice: “Documentation feels less like extra work… if you do it up front while you are building a system. This helps to pause at each major step and document any whys or gotchas that can be difficult to remember once you hit the next bump in the road during setup.
Personally for each new system deployment I create a minimum of 4 pages:
- The build process so others can see what I did.
- Any topology or overview diagrams.
- A page dedicated to systems info, requirements (system, firewall, permissions), service accounts, other dependent or connected systems.
- A how-to page full of common admin tasks.
While it is a bit of a pain to always have to do this for every system, it is a far greater pain when something breaks and you don’t have this basic info ready to go.”
This suggestion can help ease user panic resulting from tech issues so you can improve outcomes: “Sometimes users don’t realize it, but they are looking for some emotional support along with a fix for their problem. We techies tend to believe that emotions have no legitimate place in a support call. But, hey, if it helps end the call faster, it’s in our interest to be a little supportive. A friend of mine, who supports complex software, gets frantic calls from one of her clients. After listening to the problem, first thing she does is ask the client about their cat. Client loves the cat and calms down talking about it. My friend interrupts (doesn’t make sense to ‘waste’ too much time) after a few moments, says something nice about the cat, and immediately asks a specific question about the problem. She gets much better results faster. As for users who have trouble following directions, shoot them a link from your KB which has both an illustrated step by step and a link to a screen video. Don’t have them? Your company should make it easy and efficient for you to create them and should incent your team to do so. You will still get pushback and obvious questions, but it can save you some time and aggravation.”
