Data Protection in the Cloud

How to Consider Cloud Computing Data Protection Technology Challenges?

A single physical system has numerous virtual machines within virtualised environments. It is called a condition which is known as multi-tenancy. This hypervisor software is capable of maintaining isolation and segmentation between virtual machines. They augmented it with open source or commercial virtual network and virtual security appliances or add-ons.

There are, however, challenges to traditional security best practices which germs from multi-tenancy such as system segregation and separation of duties.

What is Cloud Encryption?

Encryption can be challenging to implement for performance issues, and access controls. Extending internal encryption platforms and capabilities into the cloud can seem to be equally daunting. Typical cloud encryption applications range from limited encryption only of data to encrypted connections.

Encryption is considered as one of the most practical approaches to data security, interfusing the content of any system, database, or file in such a way that it’s unlikely to decipher without a decryption key. Cloud storage providers encrypt data on receipt, passing encryption keys to the customers so that data can be safely decrypted when needed in the models which have end-to-end encryption of any data.

Practising secure encryption key management and by applying encryption, companies can ensure that only authorised users have access to confidential and sensitive data. Even if lost, stolen, or accessed externally without authorisation, encrypted data is obscure and essentially meaningless without its key.

What Are the Main Forms of Data Exposed to Theft?

• Medical Data – The last couple of years have witnessed a swell of attacks on the healthcare industry records. In common cases, the banks and retailers tend to be the cybercrime victims; however, with health care records, the scope of fraud are more. The data contained in health care files and documents are a lucrative option as it offers more information on the identity of the victims.
• Data Breach and Information Theft – Lack of identity management and proper authentication leads to data breaches within organisations. As businesses try to allocate permissions appropriate to every user’s job role, they often struggle with identity management. Poor identity management can yield gaping holes in enterprise cyber-security. Multi-factor authentication systems, phone-based authentication, one-time passwords are some of the ways to protect cloud services by making it harder for hackers to log in. Every business that has an online presence must ensure the safety of its customers and their data.
• Insufficient Due Diligence – Due diligence is the method of estimating cloud vendors whether they are implying the best practices. A significant component of this process involves verifying if the cloud provider can meet the level of service expected by an enterprise and suggest adequate cloud security controls.
• Financial Details – Bank account numbers, payroll details, credit card numbers, loan information are all extremely sensitive. The form of the Gramm–Leach–Bliley Act (GLBA) adds an extra layer of protection to the financial records. In this, any financial institution is required to explain all their information-sharing practices to their customers.

Data breach is the result of malicious and presumably intrusive action. Reputable cloud services usually have several security protocols that help them protect confidential information. The most efficient method is to use multi-factor authentication and encryption. Certain regulations, such as HITECH and HIPAA in the healthcare industry and the EU Data Protection Directive require disclosures about data protection. Following the legally-mandated breach disclosures, regulators can levy fines against an enterprise or company. In fact, it’s not uncommon for customers whose data is compromised to file lawsuits.
