I could explain to you SQL injection or a rainbow table, but in practice, I don't know how to keep my own PC safe (eg. when browsing on public WiFi). What configuration do you use to keep your computer secure?<p>1. What antivirus do you use?<p>2. Do you use a VPN? A personal one or a service?<p>3. What Firefox/Chrome plugins do you use? (eg. HTTPS Everywhere)<p>4. Do you use a program to store passwords?<p>5. What do you use for backups?<p>6. What other tricks do you have?
1. None on linux. I used MSE while I was on Windows. ufw is a a good linux firewall to have.<p>2. Personal vpn occasionally.<p>3. ghostery + adblock along with a hosts file which blocks most stuff(<a href="http://winhelp2002.mvps.org/hosts.htm" rel="nofollow">http://winhelp2002.mvps.org/hosts.htm</a>). I use privoxy while browsing on iPad<p>4. lastpass, as I have to use other computers often<p>5. Manual Copying. Dropbox+Spideroak. Plan to shift to dejadup soon.<p>Other tricks:<p>- enable 2 factor auth on google<p>- I use a truecrypt volume for stuff I don't want other people to see.<p>- Use different passwords everywhere. I use x+<common_pass>+y scheme for one-time passwords on various sites (assuming xyz.com).<p>- I personally find that staying anonymous everywhere is not worth the effort. I put in special effor when I have to.<p>Edit: formatting
