Overview of data breaches and losses

- [Instructor] In the next few chapters,…we'll take a look at our most common attacks…and delve a little bit deeper…into these few types of attacks…by first exploring what it is, why it matters,…a case study related to the attack, and finally,…how to sell these potential services…surrounding this attack.…And we'll start with data breaches and losses.…Typically, a data breach is when a hacker…finds a way to access your data…and then corrupts it, holds it ransom, or deletes it.…Therefore, the result is the loss of data…or access to this data.…
