Earlier, data was protected by difficult passwords and encryption techniques but hackers found different means to hack the password and access business information. With technological developments in various fields, this security challenge is now met by cloud computing.
Cloud computing offers the benefits of interconnected servers, various platforms to deliver internet-based computing services that are flexible and effective. Security of the data is the key risk where personal information has to be transferred or accessed from anywhere. Verification of correct data storage without any knowledge of the whole data and continuous assurance of data safety in the cloud is becoming very challenging day by day. Cloud computing enables the user to effectively store the data in a remote server and access it any time from any location.
Critical components for storing business and sensitive personal data in the cloud are data protection, disaster recovery, and storage management. Cloud computing has other benefits in the form of online storage and users can increase the space as per their needs and business requirements. Data security for such services includes various aspects like secured channels, encryption techniques, access control, and the service provider should also consider the security triad: availability, integrity, and confidentiality.
Cloud computing service providers are adopting various encryption techniques to store the data so that hackers cannot use the data for their personal benefits. 123-bit encryption technology is used and only an authorized user can have access to the data and decode it when needed. Data can be encrypted from your web browser so that the data sent cannot be read and modified along the way. Once the file is received by the cloud provider, it will be decrypted. If you want the files to be stored in an encrypted form then you should encrypt them before sending or use the cloud storage provider to encrypt them.
Data security in cloud computing also includes storage maintenance tasks like a proper backup of data, replication and easy recovery of the stored data. Reliability is a common aspect of many cloud-based service providers and users should be ensured that their data is safely stored in the server. Replication of data is performed by a mechanism like RAID or a file system and other recovery methods also include a copy on write cloning, continuous integrity checking with automatic repair.
Cloud computing service providers evaluate their resources and try to use them most effectively. There are three different types of cloud computing, private, public and hybrid. The underlying feature of each service is that it should be available to the users and effectively optimize the resources as per the model paid for. Whatever model the user chooses, the company needs to ensure that the cloud has an automated data life cycle management advanced application protection and build in data reduction for secured data storage.
Availing the service of cloud computing is definitely a plus as it reduces the user's burden of maintaining, disaster recovery, and backup and protecting the data by using the latest technology. It is also important to remember that business owners are not experts in data security and so they don't have the same expertise or storage resource to maintain the safety and integrity of the data. The concern that arose about data protection, privacy and security should not be ignored and organizations should take every step to protect their data from unauthorized access.
Security of data is the concern of various companies and cloud service offers a safe and secured space where the organizations can easily store their data. These third parties take care of all the security issues of the data stored and adopt the latest technologies and encryption methods so that there are no security breaches. This means that the service provider bears the legal responsibility of how the data is handled and protected from any unauthorized access.
