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

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

59 Domain | Object | Recommendations
60 ---------------------------------- | ------------- | ----------------------------------------------------------
61 Application-Cloud-Infrastructure-1 | Packet | Should implement a DPI.
62 Application-Cloud-Infrastructure-2 | DoS | Must implement a DoS protection.
63 Application-Cloud-Infrastructure-3 | Test | Should implement scanning tools like SATS and DAST.
64 Application-Cloud-Infrastructure-4 | Log | Should implement security tools (IDS and IPS).
65 Application-Cloud-Infrastructure-5 | App integrity | Applications must be signed by the code signing authority.

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