Watch what you post• The biggest risk to our privacy is what we post ourselves
• Be aware that anything you post online can be copied and pasted
• If it’s really embarrassing or really a secret, don’t post it online, even if you have the tightest possible privacy settings
Keep hackers at bay• All privacy bets are off if hackers get user names and passwords
or break into one of your accounts
• Even if you practice great security, there is always a chance of a data breach at some company or agency with access to your data
Security tips• Use strong passwords, change them periodically and don’t use
the same password for multiple accounts
• Check your online credit and bank accounts
• Use security software and keep it and your operating system and applications up-to-date
• Use WiFi security
• Use the privacy tools associated with your social networks
• Only provide personal or financial information to websites you know and trust
• Be aware of the mobile and social networking apps you’re using
• Know how to use your browser’s private or “ingonito” mode and how to erase the history from your browser.
How tracking cookies work
1. You visit a website that has an ad on it that’s placed by one of the advertising networks. The ad is delivered from a server owned by the advertising network
2. The network puts a cookie on your machine that records the ad that was shown and the site you visited
3. When you visit another site that displays ads from the same network, the cookie is updated with information about the current ad and current site.
4. Over a period of time the network can get a pretty good idea of sites in its network that you’ve visited
How to delete & block tracking cookies
• Many security products can be used to remove tracking cookies and the major browsers also have tools to remove them
• DoubleClick, which is owned by Google, offers instructions on how to opt out of cookies
• All the browser companies have agreed to include a “do not track” feature in future browsers, but tracking will be the default setting unless you change it. Mozilla Firefox, the first to implement this feature
Control mobile location sharing
• Some mobile apps are designed to share your location: Use them thoughtfully and only share with those you trust.
• Review setting periodically. A “friend” could become an ex-friend.
• Pay attention to the permissions on all mobile apps. Only use location-aware apps that you trust
Don’t overlook the “obvious”• Watch what you say on your phone while you’re in
public — people around you might be listening
• Be aware of others viewing your screen. Consider getting a privacy screen for your laptop
• Shred your old financial records and other confidential documents before throwing them in the trash or recycling bin
Facebook privacy settings
Access general privacy settings by clicking down arrow in upper right corner

Facebook inline privacy controls
• Whenever you add content, you can select the audience
• Be aware that whatever audience you last selected remains for subsequent posts until you change it
Facebook system-wide settings
Control those apps
