Ever since the cloud computing solutions have been introduced, they have changed the way small and large businesses work today. Cloud indeed comes with lots of benefits which are hard to ignore but there are tons of concerns when it comes to the cloud security. The cloud security alliance has come with some of the serious security threats that prevail in cloud computing.
Here are some of the biggest security concerns explained:
- Data Breaches
The first and foremost cloud threat is data breach which results in the loss of personal and credit card info. Cloud computing has introduced many avenues of attacks. There is a need of hypervisor operation and virtual machine operations. It is even a question of concern that whether absolute security can ever exist in cloud. These breaches are like nightmares for the organizations because a lot of sensitive data may fall into the hands of competitors. Flaw in the application does not just allow the hacker to get access to the client’s data but also the data of every other client attached in the row. The more copies of data you create and maintain on the cloud, the more prone it is to security breaches.
- Data Loss
When an intrusive action takes place or malicious content is released, data loss is inevitable. Data loss occurs when the disk drive dies and you have no backup created for that data. It can also occur when the owner has lost the key. Even losing small amount of data can result in disaster. Whether it is the business or its consumers, data loss is quite terrifying especially if it is a permanent loss. There are lots of techniques of preventing data loss but no matter what you do, it occurs anyways.
- Account Hijacking
Although account or service hijacking may sound to be a concern of elementary level but it can become a huge problem. Softwarevulnerabilities and phishing,loss of passwords and buffer overflow attacks can results in loss of control over the user account. When an intruder takes control of your account, he can manipulate data, eavesdrop on your transactions and even provide reputation damaging responses to your customers. Your reputation will be at stake if your account is hijacked. Through hijacking, if the credentials are lost, the wrong party can get access to systems and accounts of individuals. This would ultimately compromise on the availability, integrity and confidentiality of the services.
- Insecure APIs
API defines how a third party connects application to the service by offering verification that the third party which is producing the application is the one who he actually says he is. If an organization is relying on weak APIs, the organization is exposed to a number of security issues related to integrity, confidentiality, accountability and availability.
- Denial of Service
This is one of the oldest disputes of online operations but it is still a threat. The automatic service requests must be screened or detected when the operations are tied up. However, today the attackers have become sophisticated and it has become hard to determine where the incoming traffic is coming from. When the denial of service pops up in front of the customer service, the service might impair without any shut down and the customer might get billed for the cloud service for the resources which have been consumed during the attack.
These are just a few threats to name but that does not mean cloud is no good. The truth is, there is no escape for cloud, we simply need improved solutions to overcome these vulnerabilities so that the security threats can be minimized and the actual benefits of clouds are reaped.
