About you?

What is information?

Information vs Data?

How is information safe?

What is information?

Some problems:

• Reperesentation and Storing

• Processing

• Transfer

• Safety

Information is a abstract notion, to denoteanything that is a result of interaction.

Information vs Data

• What is Data?

Information vs Data

Data is plain fact

Information vs Data

Information Data

Data is any sort of raw fact. Information is data in a usable form, ussually processed in some way. It’s data plus interpretation.

- Subjective - Objective

- Abstract - Visual

- Result of interaction - A component of interaction

How is “information safe”?

• Confidentiality

• Integrity

• Trust

• Others…

The safety of information is guarantee for some properties of information. In a specific context,

specific properties must be guarantee

Why must we care

Because:

• Information is very very important

• Data is not safe

• Information safe is very interesting

• Finally, it’s your subject

Goal and objectives• Understand the basic principles andconcepts of “information safe”

• Study main aspects of Network security

=> Then:

• Have a good background about “informationsafe”

• Can study other fields such as datasecurity, database security, networksecurity, web security, …

• Can design security solutions
