• Stalkers

How can you be tracked?

• Interactions with your Internet Service Provider (ISP)
• “Like” buttons and advertisements

• Keyloggers
• Logs on the websites you visit
• Wifi (and wired) snooping

Get Organized: Week 5 Materials

A bit late, but here are the slides and handout from week 5 of the ‘Get Organized’ series. Week 5 was about budgeting.

For those who attended the series, please send me feedback of the constructive and/or showering-in-praise type. Let me know which sessions you liked (or didn’t), whether or not the structure was useful, what has worked for you, what really didn’t work for you, what you wish I’d covered (or covered more), etc. And if you qualified for those 2 free hours of help, I will be in touch at the end of the month!

For those who didn’t attend, or missed some sessions, if anyone is really interested and would definitely come out to a second offering of the series (perhaps a bit reorganized; probably in June/July), please contact me at laura @ bettertogetherdesign.com.

• Verifying identity (secure web browsing, encrypting email…)

• Email phishing and scams
• Privacy and tracking
• Firewalls, Routers, and Wifi

There is still space left in the course, so feel free to register by leaving a comment below.

Computer Security Session 1: Passwords, Overview

version 1.0

Passwords

Passwords are like housekeys for computer services. They are intended to be secrets that allow you to access resources, but deny access to others.

Here are some questions to ask yourself about passwords:

• What are the passwords protecting?
• If one password is breached how many other computer services become vulnerable?
• Who else knows your passwords? How much do you trust them?
• What services have your passwords? How much do you trust them?
• How many passwords do you have to manage?
• How do you manage your computer passwords?
