14 - **authentication**: Authentication is the security process that validates the
15 claimed identity of a device, entity or person, relying on one or more
16 characteristics bound to that device, entity or person.
18 - **Authorization**: Parses the network to allow access to some or all network
19 functionality by providing rules and allowing access or denying access based
20 on a subscriber's profile and services purchased.

25 ---------------------------- | -------------- | --------------------------------------
26 Application-Cloud-Download-1 | authentication | Must implement authentication process.
27 Application-Cloud-Download-2 | Authorization | Must implement Authorization process.

35 - **Deep Packet Inspection**: **DPI** provides techniques to analyze the payload
36 of each packet, adding an extra layer of security. **DPI** can detect and
37 neutralize attacks that would be missed by other security mechanisms.
39 - A **DoS** protection in order to avoid that the Infrastructure is no more
40 accessible for a period of time.
42 - **Scanning tools** such as **SATS** and **DAST** assessments perform
43 vulnerability scans on the source code and data flows on web applications.
44 Many of these scanning tools run different security tests that stress
45 applications under certain attack scenarios to discover security issues.
47 - **IDS & IPS**: **IDS** detect and log inappropriate, incorrect, or anomalous
48 activity. **IDS** can be located in the telecommunications networks and/or
49 within the host server or computer. Telecommunications carriers build
50 intrusion detection capability in all network connections to routers and
51 servers, as well as offering it as a service to enterprise customers. Once
52 **IDS** systems have identified an attack, **IPS** ensures that malicious
53 packets are blocked before they cause any harm to backend systems and
54 networks. **IDS** typically functions via one or more of three systems:

64 Domain | Object | Recommendations
65 ---------------------------------- | ------------- | ----------------------------------------------------------
66 Application-Cloud-Infrastructure-1 | Packet | Should implement a DPI.
67 Application-Cloud-Infrastructure-2 | DoS | Must implement a DoS protection.
68 Application-Cloud-Infrastructure-3 | Test | Should implement scanning tools like SATS and DAST.
69 Application-Cloud-Infrastructure-4 | Log | Should implement security tools (IDS and IPS).
70 Application-Cloud-Infrastructure-5 | App integrity | Applications must be signed by the code signing authority.

78 For data transport, it is necessary to **encrypt data end-to-end**. To prevent **MITM** attacks,
79 no third party should be able to interpret transported data. Another aspect
80 is the data anonymization in order to protect the leakage of private information
81 on the user or any other third party.
83 The use of standards such as **IPSec** provides "_private and secure
84 communications over IP networks, through the use of cryptographic security
85 services, is a set of protocols using algorithms to transport secure data over
86 an IP network._". In addition, **IPSec** operates at the network layer of the
87 **OSI** model, contrary to previous standards that operate at the application
88 layer. This makes its application independent and means that users do not need
89 to configure each application to **IPSec** standards.
91 **IPSec** provides the services below :
93 - Confidentiality: A service that makes it impossible to interpret data if it is
94 not the recipient. It is the encryption function that provides this service by
95 transforming intelligible (unencrypted) data into unintelligible (encrypted)
97 - Authentication: A service that ensures that a piece of data comes from where
98 it is supposed to come from.
99 - Integrity: A service that consists in ensuring that data has not been tampered
100 with accidentally or fraudulently.
101 - Replay Protection: A service that prevents attacks by re-sending a valid
102 intercepted packet to the network for the same authorization.
103 This service is provided by the presence of a sequence number.
104 - Key management: Mechanism for negotiating the length of encryption keys
105 between two **IPSec** elements and exchange of these keys.
107 An additional means of protection would be to do the monitoring between users
108 and the cloud as a **CASB** will provide.
