It is important to make a good password • Stops others from stealing your information • Stops others from stealing your identity • Stops others from getting you in trouble

What is Identity Theft? • It is when someone impersonates another person • Physical identity theft is a minor problem • Electronic identity theft is a major problem

What identifies you Electronically? • Identification numbers (social security number, student id, . . . ) • Usernames or account names • Passwords or pin numbers

Where could identity theft occur • Anywhere you have personal information • Accounts (School, Facebook, Bank, Amazon, Credit Card etc. ) • Emailing personal information

You should NEVER… • Give your password to anyone • A friend or family • An IT person • An anonymous email • Be careful when unexpected requests for passwords appear

Also, be careful about social engineering • • People just flat out asking you to sign in so they can "test" the system People using personal information to "guess" your password Someone watching over your shoulder to see what you type Do NOT write down your information and tape it to your keyboard, desk drawer, etc.

What doesn't make a good password? • The default password, whatever it is • A word spelled backwards, in any language • Your name, your boy/girl friend's name • A word with a number tacked onto the end • ANY word in English • Standard number for letter • ANY word in ANY language replacements 3=E, 0=O • Non words that have cultural • Short passwords meaning (R 2 D 2, C 3 PO)

Some Rules: • Keep your password to yourself • You should never have to give your password to a person • Keep a secure password • Keep separate passwords for different systems • Always be careful with your password

Why these rules for passwords? • Identity Theft has become a major problem • In most systems, your account name or number along with your password are your identity on that system • Most account names are public information

Parts of an Email Message

Parts of an Email Message • TO: email address(es) of primary persons • CC: (carbon copy) email address(es) of other people who may be involved/interested in the contents of the message (Think FYI) • BCC: (blind carbon copy) email address(es) of other people who will receive a copy, but the fact that they have received a copy is concealed from other recipient(s) • Use this when sending an email to a group of people where you don't want to share membership/emails with the group • Use it when you don't want the person bcc'd to be forced to acknowledge that they received a copy • It also stops "reply all" • Subject: short summary of contents • Body: message

Email Attachments • A file sent along with an email message • File format is maintained • Size is usually limited • In most email clients: • Find the attach button • Select the file you want to attach • Be careful of attachments • Don't open attachments from people you don't know/trust • Zip or self-extracting zip files (. zip or. exe)

Email Etiquette • First and foremost THINK about what you are sending • Would you put it on paper? • Someone might print it out • Would you want it to last forever? • Most systems are backed up, and most people are capable of saving email messages • Would you want it used in court? • System records are subject to subpoena • Would you want it published? • Some records are subject to the laws

Email Etiquette • Don't "e-mail angry" • Be careful with confidential information • Keep it clean • Organize your message - you don't want to read something that is a mess • Content – be clear in your message • Be clear in your subject line • You want the recipient to read it • People receive tens to hundreds of email messages a day • You don't want it caught in a spam filter

Email Etiquette • Beware of the "reply all" • Briefly introduce yourself • Your e-mail is a reflection of you • Be concise and to the point • Answer all questions and preempt further questions • Use proper spelling, grammar & punctuation • Pay attention to the TO and CC fields

Final Tips • Be careful when you don’t recognize the sender • Notice the actual email address • Don’t respond to threats – “send us your password and email before you lose all your contacts” • Notice phishing emails - poor grammar or misspelled words can be an indicator • Keep passwords private and update them every 90 days
