We’ve talked about Malware and the importance of Keeping Computers Up To Date, and even just about The Things We Should Fear. But what new hazards are unveiled when you connect two or more computers together? When some of those computers aren’t on your own network? When malusers are out there trying to break into your network? When you’re actually inviting everyone into your network by running servers and services? Should you just outsource everything? Or are there tools available for the Non-Profit SysAdmin to help secure your networks?
We’ll talk about the hazards of running a public network, and go over a list of tools and software.

- Another secure firewall: pfSense

- Vulnerability not acknowledged by vendor:
- City knew of massive cyber breach days before admitting it | CBC News

- Bugs in the software
- Errors in procedures
- “If the data was in the cloud it would have been safe”
- What is The Cloud?
- Somebody manages the servers, still subject to human error
- But reduces the human interaction that is needed
- Maybe if everything is run by robots…
- But that’s not the way Nonprofits operate, engaging people to be more involved
- Open Source groups want more interaction, so still room for error
- eg. LibreOffice: Get a professional to manage website? Or keep local group involvement? No to robots
- Robots have programmers too
- One more level of abstraction
- Problems solved?
- Email spoofing, phishing schemes: Joe Jobs, third-party addressbooks breached
- Could contact the apparent sender, but that person may not be involved in the message at all
