4 What is it? A collective set of policies, standards, processes and procedures that limits or controls access to, and use of, information to authorized users. IS is the process of protecting data from unauthorized access, use, disclosure, destruction, modification, or disruption. 3

5 Is Information Security something new? Julius Caesar is credited with the invention of the Caesar cipher c50 B.C. to prevent his secret messages from being read should a message fall into the wrong hands. WW II brought about significant advancements in IS in that formalized classification of data based upon sensitivity of information and who could have access to the information was introduced. The rapid growth and wide spread use of electronic data processing and electronic business conducted through the Internet fueled the need for better methods of protecting these computers and the information they store, process and transmit. 4

6 Information Security Core Principles Confidentiality Holding sensitive data in confidence, limited to an appropriate set of individuals or organizations. Integrity Data can not be created, changed, or deleted without authorization Availability The information, the computing systems used to process the information, and the security controls used to protect the information are all available and functioning correctly when the information is needed. The opposite of availability is denial of service (DOS)

7 Password Construction Techniques Constructing tough-to-crack passwords is an important way that you can protect information and your identity. A good password must also be unique. When constructing your password, never use easy-to-guess password elements such as: Your User ID (jsmith) A phone number or street address Names of family members, close friends, coworkers, pets, etc. Your title or function (secretary, manager, security, etc.) Names of places

8 Password Protection Technique Once you ve constructed a hard-to-guess password, these are some important steps you should take to protect it: Do not give your password anyone even if they claim they have a valid business reason. Change your passwords on a periodic basis as even the strongest passwords can be guessed or misplaced over time. In most cases, your business will select the appropriate period and it will be enforced automatically by the operating system or application. Watch out for applications that "remember" your password, so that you do not have to input the password again. Typically these applications have a checkbox on the log in screen that asks: "Remember my ID on this computer?" Always select no in response to this question.

10 Types of Social Engineering Psychological Subversion Establishing a relationship with an insider to gain access to continuing stream of information Masquerading Impersonating people with legitimate access or a need to know to gain access Shoulder Surfing Stealing information by watching a legitimate user type in a password

11 Examples of Social Engineering Tailgating Entering secure locations by following behind someone with legitimate access Dumpster Diving Finding improperly discarded information Look out for Rushing Name-dropping Intimidation Small mistakes, for example: misspellings, misnomers, odd questions, etc. Requesting forbidden information

12 Identity Theft What is it? A component or subset within IS principles and the CIA Triad. According to the non-profit Identity Theft Resource Center, identity theft is "sub-divided into four categories: Financial Identity Theft - using another's name and SSN to obtain goods and services Criminal Identity Theft - posing as another when apprehended for a crime Identity Cloning - using another's information to assume his or her identity in daily life Business/Commercial Identity Theft - using another's business name to obtain credit
