The cloud is the newest frontier of the digital space، but with every new frontier comes new and unforeseen dangers. Businesses that depend on the cloud for storing their data have run into a number of problems regarding how to secure that data. According to Gartner، as much as 95% of data breaches occurring on public cloud server through to 2022 are likely to be because of the customer. So how do we secure our cloud data to avoid ending up within this statistic?، as the Technical Times said
Encrypting Data Regardless of Where it is Encryption is a useful tool to ensure that data doesn't get waylaid on its way from server to client. Based on the definition by Digital Guardian، we can say that encryption is a method of garbling a message so that it can only be understood by someone who has the correct key to restructure that message and make sense of it. Most of the data that we encrypt is stationary or "at rest" data. This refers to data that is stored on local disks or physical storage. The more interesting usage of encryption is by using it with "in flight" data or data that is being transferred over a network or stored on a cloud server. Thus ensures that the data is secure until the person who needs to access it presents it with the decryption key. Generally، encryption utilizes TLSSSL connections or IPsec VPN tunnels in order to create encrypted channels of communication for in flight data. Businesses can seek to utilize this methodology when securing their data on the cloud.
Closed Access Security Broker (CASB) Methods The direction that many companies decide to go when it comes to securing their cloud data is by employing a CASB، managed through an API. Because of the scalability of an API-based CASB، they tend to be adaptable، and able to be deployed in both small and large use cases. What a CASB seeks to do is to monitor network activity and to limit high-risk operations such as downloading of files and information distribution from the unsecured Internet. Many cloud vendors have moved towards making CASBs available، as part of their included offerings for business customers. The CASB system is defined on a per-user basis، so that even if a user tries to access the data through their personal device، the same security measures would be applied to that device in keeping with what that particular user is allowed to access. Computer World notes that a CASB is especially useful in the case where a company's security perimeter only reaches the edge of the company's network، and data from the business' server is being accessed outside of the company.
