"We are moving to the Cloud..." This is the new moda and we are in a new era. On-Premise Infrastructures are disappearing or are in sharp reduction due to the several advantages the Cloud provides: Show
So, it seems that Cloud can resolve most of the problems that Managers have to face on every day. Is this true? If everything have been analysed correctly, I will continue to say "no". Cloud cannot resolve all the security an Organization has with just a snap of the fingers! Data is moved to another entity, so other layers, risks and threats are introduced. On the market there are several XaaS cloud models but the 3 fundamentals are:
2. Platform as a Service (PaaS): in this model, the Customer loses the controls of the Infrastructure layer and OS layer. Indeed, the Cloud Service Provider installs, maintains and administers the OS. The OS layer is secured by the CSP by using its internal security policy. In this model, in addition to the IaaS model, other questions from the Cloud Customer side arise:
3. Software as a Service (SaaS): most of the controls are ceded to the Provider. Customer moves and creates the data on the new cloud platform. The Customer is ultimately responsible for any unauthorized disclosure of PII (Personal Identifiable Information) in the Cloud. There are no contracts or clauses that remove/cover this responsibility. Funny, eh? Customers using this layer will ask themselves:
For all the models, there are several security questions that would come into mind, such as:
The list of questions is long and should become longer during the Business Impact Analysis (BIA). As an Organization, do not move to any Cloud model before you can understand the risks of each one. Adherence to Standards like ISO, Contracts and SLAs should cover your questions and more. Make sure to read carefully the contract your Cloud Provider is offering to you. Do not sign it without first conducting a BIA and make sure to engage a Cloud Security Architect. Moving too fast to the Cloud can be tricky and can cost a huge amount of money. Upload data in the Cloud can be free but downloading the data from the Cloud to move to another Cloud Provider or to move back to On-Premise have some costs. READ THE CONTRACT and ENCRYPT YOUR DATA!

Personally Identifiable Information (PII) is a legal term pertaining to information security environments. While PII has several formal definitions, generally speaking, it is information that can be used by organizations on its own or with other information to identify, contact, or locate a single person, or to identify an individual in context. Non-sensitive PII can be transmitted in unsecure form without causing harm to an individual. Sensitive PII must be transmitted and stored in secure form, for example, using encryption, because it could cause harm to an individual, if disclosed. Organizations use the concept of PII to understand which data they store, process and manage that identifies people and may carry additional responsibility, security requirements, and in some cases legal or compliance requirements.

Personally Identifiable Information (PII) in Privacy LawPII and similar terms exist in the legislation of many countries and territories:
What Qualifies as PII?According to the NIST PII Guide, the following items definitely qualify as PII, because they can unequivocally identify a human being: full name (if not common), face, home address, email, ID number, passport number, vehicle plate number, driver’s license, fingerprints or handwriting, credit card number, digital identity, date of birth, birthplace, genetic information, phone number, login name or screen name. Beyond these clear identifiers, there are “quasi identifiers” or “pseudo identifiers” which, together with other information, can be used to identify a person. For example, according to a US governmental study, 87% of the US population can be uniquely identified by a combination of gender, ZIP code and date of birth. Pseudo identifiers may not be considered PII under United States legislation, but are likely to be considered as PII in Europe. Who is Responsible for Safeguarding PII?From a legal perspective, the responsibility for protecting PII is not solely attributed to organizations; responsibility may be shared with the individual owners of the data. Companies may or may not be legally liable for the PII they hold. However, according to a study by Experian, 42% of consumers believe it is a company’s responsibility to protect their personal data, and 64% of consumers said they would be discouraged from using a company’s services following a data breach. In light of the public perception that organizations are responsible for PII, it is a widely accepted best practice to secure PII. A common and effective way to do this is using a Data Privacy Framework. Creating a Data Privacy FrameworkA Data Privacy Framework is a documented conceptual structure that can help businesses protect sensitive data like payments, personal information, and intellectual property. The framework specifies how to define sensitive data, how to analyze risks affecting the data, and how to implement controls to secure it. While there are established data privacy frameworks such as the Payment Card Industry Data Security Standard (PCI DSS), the ISO 27000 family of standards, and the EU General Data Protection Regulation (GDPR), there are benefits to creating a custom framework for your organization. A custom Data Protection Framework will help you put an emphasis on the most sensitive and valuable data within your organization, and design controls that are suitable for your organizational structure, culture, regulatory requirements, and security budget. Follow the steps below to create a custom Data Privacy Framework. ClassificationDefine, assess and classify PII your organization receives, stores, manages, or transfers. For each type of PII, identify:
AssessmentConduct a Privacy Impact Assessment (PIA) to determine, for each type or classification or PII, how it is collected, where it is stored, and how it is disposed of, as well as the potential security risks for each type of PII. Compliance Environment
PII Security ControlsThe Data Privacy Framework should define which security controls the organization needs to have in place to prevent data loss or data leak:
