With the rise of cloud computing, several security concerns have been expressed by organizations on the adaptation of cloud technology. Let’s have a look at the cloud security vulnerabilities and its mitigation for the enterprises.
Even though some of the cloud service providers take security seriously, the reality is that there are a few of them who still consider security as second priority taking the ‘cost factor’ into consideration. This would be fatal because the cost factor cannot be quantified by any means taking the security factor into account. The breach of data in the cloud directly implies the breach of trust by the cloud service providers to its clients.
As CIOs become increasingly comfortable hosting critical software in the public cloud, there are certain security challenges that are crucial. Here’s a look at some of the cloud security risks
Malicious attacks such as DDoS attacks on the public cloud infrastructure are nothing new to enterprises. In addition to crippling the cloud availability that run critical infrastructure in the cloud, DDoS attacks also cost large amounts of processing power bill that the cloud customers or end-users will have to pay.
Data Breach and Loss
If a hand-held device without adequate security used for accessing the administration aspect of the cloud is lost or misplaced — will allow unauthorized person to access sensitive information and data theft in the cloud.
When your crucial business data is on the cloud is breached and stolen, will prove fatal for an enterprise business. Any breach in the cloud infrastructure or loss of critical data from the cloud storage will only reaffirm the fact that data security is the lifeline of business. It has often been observed that DDoS attack is only a diversion for a greater security threat, such as an attempt to steal or delete data.
Insecure APs, Apps and APIs
One of the key reasons of data breach is due to insecure access points which uses various interfaces that are used by the cloud users. Hackers usually trace such insecure entry points or vulnerabilities and exploit them.
One of the issues which I see is that cloud based apps are designed and deployed for usability rather than its security. Traditionally, the CIOs have the notion that since the cloud based apps are functional, the apps are void of innate vulnerabilities. Often the cloud based app’s code and it’s APIs determines its security.
Another instance is the possibility of a malicious hacker using application vulnerability such as insecure APIs, cross-site scripting, SQL injection or other means to steal the sensitive data in the cloud.
Internal Security Threat
Insider threat in enterprises due to weaker authentication and identity management can lead to employees having unauthorized access to the cloud infrastructure and have disastrous effect on the organization. Due to the sensitivities involved in an insider threat, quickly identifying the insider can be a little time consuming and tedious process.
Another issue with the cloud users is the misconception that providing cloud security services is the sole responsibility of the cloud service providers. While the primary security in the cloud is provided by the cloud service providers, the cloud users should realize about ‘insider’ threat and they should have a robust internal security policy in place to provide comprehensive cloud security.
