The introduction of the microprocessor, a single chip with all the circuitry that formerly occupied large cabinets, led to the proliferation of personal computers after 1975.
A side effect of hosting data in the cloud is that you cannot control who has physical or logical access to the servers on which your data is stored and processed. When an organizationa€™s database is in the cloud, it becomes possible for people to gain access. DBaaS regulatory compliance refers to the actions taken by organizations to comply with the laws and regulations that apply to databases hosted in the cloud. A performance attack can be caused by flooding the database with artificial requests (DDoS) or by targeted attacks that impact a sensitive asset in the database.
The challenge of discovering sensitive data falls into two categories: finding it in structured data and in unstructured data (databases are structured data). In an SQL injection attack, malicious SQL statements intended for execution by a database are inserted into an entry field on a website. DBAs, software developers, quality assurance personnel and others (whether employees or external partners) frequently require extensive access to databases in order to perform their roles.
Cloud-hosted applications and databases typically utilize resources that are shared by multiple customers, or tenants.
For computers generally referred to as PCs, see IBM Personal Computer and IBM PC compatible.
While many of the traditional on-premises risks remaina€”data leakage risk from privileged users with access to the data, the presence of unidentified sensitive data and SQL injection attacks are some examplesa€”the cloud introduces its own additional risks.There are also ways to leverage the cloud by outsourcing some of the risk mitigation to the cloud provider. More specifically, certain employees of the cloud provider will have access to the servers, and therefore, your data.


Cloud providers maintain physical data centers in multiple locations for reasons of performance and redundancy.
All it would take is to crack the database password or exploit some other weakness in the security configuration.
In actuality, cloud-hosted databases are more resistant to performance attacks because of their inherent agility. Third-party vendors offer technology that is capable of scanning all of an enterprisea€™s databases and automatically discovering sensitive data. One possible result is that the server will expose data from the database that it should never return. This essentially means that the organization cannot block their access, even to sensitive databases, without preventing them from doing their jobs. Two of these shared resourcesa€”memory and diska€”present the danger that one tenant may be able to access sensitive data belonging to a different tenant.
This introduces a possible avenue of data theft over which you have no control at all.In DBaaS environments, where the provider provisions the software, you are forced to trust the provider and its security practices to a much greater degree. DBaaS deployments can be protected by network firewalls that function similarly to on-premises firewalls. It is possible that solutions with the equivalent functionality, stability and performance are not even available yet for cloud environments. The flexibility and scalability of DBaaS environmentsa€”and thus their resilience in the face of a performance attacka€”will always be greater than any standard on-premises database. These types of attacks exploit a security vulnerability in a Web applicationa€™s software and sometimes also in a closed source application.The first line of defense against SQL injection attacks is one that must be implemented by developers on the code level.


On the other hand, it is dangerous and unnecessary for these types of roles to have total and unfettered access to all of a companya€™s sensitive data. Second, they offer automatic backups that allow customers to restore data from their own backups. Any organization that has to comply with regulations in a DBaaS environment has to use third-party tools to achieve compliance.
Finding sensitive and regulated data within enterprise databases is one of the key challenges to implementing data security and regulatory compliance. The major cloud providers do not currently offer off-the-shelf solutions to this threat; instead, it is expected that third-party solutions be used. These risks are part of the price you pay for enjoying the benefits of sharing resources with other tenants. Third, they offer data replication services that mirror their clientsa€™ data, sometimes to other regions, for load-balancing and performance purposes. All major cloud providers provide basic firewalls that, with a few simple rules, can ensure that access to the database will only be granted from the organizationa€™s own network. While the major DBaaS providers do not offer tools for the automatic discovery of sensitive and regulated data, third-party tools are available.
