Which communication standard relies on the concept of "Web of Trust"? SELECT THE CORRECT ANSWER Public Key Infrastructure (PKI) Pretty Good Privacy (PGP) Federated identity IPsec
Pretty Good Privacy (PGP) PGP does not use a hierarchy of CAs, or any type of formal trust certificates, but relies on a "web of trust" in its key management approach. Each user generates and distributes his or her public key, and users sign each other's public keys, which creates a community of users who trust each other. This is different to the CA approach where no one trusts each other, they only trust the CA.

An SSID (Service Set Identifier) is a name (up to 32 characters) that uniquely identifies a wireless network. It is recommended to disable the broadcasting of the SSID. What security does this provide? SELECT THE CORRECT ANSWER Prevents man-in-the-middle attack Prevents detection by packet sniffing tools Prevents denial or service attacks Provides security by obscurity
Provides security by obscurity SSID should be disabled if the network is not for public use, but realize that hiding the SSID is not true security because any hacker with basic wireless knowledge can easily discover the SSID. Hiding the SSID is security by obscurity as it does not secure the network; you must enable encryption. Even when broadcast is disabled, the SSID can still be detected using packet sniffing tools.
An airline has taken measures to protect the passenger data (name, address, passport number) by storing it in one file and the travel history in the other file. In addition, each passenger is given a passenger number (P8705), so this data is added to the dataset. By separating passenger data and travel history, it is possible to find which passenger belongs to which passenger number in one file. the other file contains travel behaviour belonging to the passenger number. These files are kept separately with role-based access control. In this way, the travel data is analyzed without each employee knowing the true identity of the passenger. This limits the dissemination of sensitive information within the company and improves the protection of passengers' personal data. Which data protection measure is described here? SELECT THE CORRECT ANSWER Pseudonymization A1, E1 A6, E1 A6, E6
Pseudonymization The GDPR defines pseudonymization as "the processing of personal data in such a way that the data can no longer be attributed to a specific data subject without the use of additional information."
