Knowledge Check: Identity and Security as a Service Quiz Answer

Along with SaaS, PaaS and IaaS, service providers may also offer “as a service” models such as identity as a service (IDaaS) and security as a service (SECaaS).  

IDaaS provides organizations within an SSO solution for use in a web-based environment. This service is usually cloud-based and a pay-for-use model. 
SECaaS provides a subscription-based security solution that doesn’t require hardware to be run on an organization’s premises. It is based on the software as a service concept.

Q.1 Based on your understanding of service models and the definition of each of these models, determine whether each statement regarding IDaaS or SECaaS is TRUE or FALSE. (D7, L6.1) 

SECaaS is based on the SaS concept.  

True

False

Q.2 SECaaS provides a slower provisioning and any security tools available are limited. 

True
False

Q.3 Log management, reporting, authentication, access control and SaaS are all core features of IDaaS.  

True
False

Q,4 Antivirus solutions are really the extent of SECaaS.  

True
False

Threat to Storage Types Quiz Answer

The following are three types of cloud storage options available to an organization: 

Block: Used where low-latency, dedicated storage is required, often by systems such as databases. 
File: Usually supported by network attached storage (NAS) and used where applications and users require access to shared data or files. 
Object: Used when data is stored as an object that is the file and its metadata which is attached to a customer of applications identifier.

Regardless of the storage type, the threats and safeguards or countermeasures remain largely the same.

Directions: Match the critical area to the potential threat or risks the area introduces to storage types. (D7, L6.1) 

Q.1. The accidental dissemination of private or critical data to unauthorized recipients. Storage providers might accidentally make data incorrectly, thus making it public.  

Rogue devices
Shared resources
Data leakage
Lack of backups
Data privacy
APIs
Outsourcing control

Q.2. Maintaining access to private data is outside of your direct control. It is impossible to ensure the correct access, which might result in the loss of privacy. 

Rogue devices
Shared resources
Data leakage
Lack of backups
Data privacy
APIs
Outsourcing control

Q.3. Multi-tenanted providers offering shared access to devices such as servers. The data of organization A might become visible to organization B. If organization A uploads malware, all users of the shared resource might be infected. 

Rogue devices
Shared resources
Data leakage
Lack of backups
Data privacy
APIs
Outsourcing control

Q.4. The shared storage provider now has access to all systems (their IT personnel) and thus the data. There is no direct visibility into the actions of these individuals, making malicious activity hard to see and even harder to prevent. 

Rogue devices
Shared resources
Data leakage
Lack of backups
Data privacy
APIs
Outsourcing control

Q.5. Lack of automated recovery points (copies). Not all storage providers offer an automated service. A lack of copies can render an organization unable to function.  

Rogue devices
Shared resources
Data leakage
Lack of backups
Data privacy
APIs
Outsourcing control

Q.6. The use of BYOD and IoT that can introduce devices with weakened or no security. They are also unregistered devices having access to corporate data. 

Rogue devices
Shared resources
Data leakage
Lack of backups
Data privacy
Outsourcing control

Q.7. to assist cloud migration and acts as an intermediary between users and storage providers. Can lead o a break in confidentiality, integrity, privacy, availability and accountability. 

Rogue devices

Shared resources

Data leakage

Lack of backups

Data privacy

Outsourcing control
