Internet Security

The tutorials I watched were Explaining Cookies, Email Attachment Tips, and Explaining What Firewalls do and don't do.  In Explaining Cookies I learned there is a type of cookie called a tracking cookie that tracks where you go on the Internet and reports this information to advertisers.  The advertisers then use this information to place advertisements on webpages.  I found it surprising that they can use these cookies to find detailed information about users lifestyles, spending habits, and more.  In Email Attachment Tips I learned that bad grammar is the first sign that something is a scam or virus.  Bottom line is to trust your instincts, if it seems suspicious it probably is.  In Explaining What Firewalls do and don't do I learned that you need both hardware and software firewalls.  Hardware firewalls do no block viruses from the Internet.  Software firewalls are the second line of defense against these.  They can do many things like warn you against dangerous Internet activity.  These are all things that I will share with others so that they are better informed about Internet security.
