The following are the most common cloud security threats for individuals and businesses. At any one point, you may be a victim of any of these threats. Although the extent to which these threats can harm you varies, they may disrupt your convenience or operations of your business.
By far, losing data remains one of the most common cloud security threats. You can lose your data in different ways. For example, hackers may succeed in attacking your account. If they do so, they may decide to erase your data as a way of inconveniencing your operations. Given that you may not be backing up your data losing it to criminals may disrupt your operations substantially. Second, errors of your cloud service provider can also lead to data loss. If hackers succeed in accessing the cloud, they may destroy all the data found in the cloud. This means that you will lose your data.
Criminals can access your account and hijack it. They can then hold the account for ransom. Alternatively, criminals can hijack an account and use it for their malicious activities. For example, they may intentionally manipulate the data to disrupt your operations. Alternatively, if they are holding a business account, they may release confidential information to the public. Releasing your confidential information to the public may end up damaging your reputation. Also, hackers can hold an entire cloud storage service at random. In such a case, they will damage the operations of several businesses and individuals who store their data with the particular cloud service.
Application Programming Interface (APIs) are special protocols that software engineers develop to help people access and use cloud services. It is based APIs that you can access your account to any cloud storage service, upload data, move the data and even delete some files. Therefore, APIs make life easy for individuals and businesses who store data on cloud services. However, weaknesses in APIs makes cloud storage services very vulnerable to attacks. Criminals can use insecure APIs to access cloud storage services. This puts many cloud storage services at risk.
People store sensitive data in the cloud. Similarly, businesses store confidential information in the cloud services. Businesses may store data about their operations or clients. Cyber criminals can access the data even when the data is in the cloud. This can happen in several ways. For example, criminals may succeed in hacking into a particular cloud storage service. Although this is a rare occurrence, it is possible. If it occurs, criminals may steal your personal data. They may then use the data to defraud you or others. Similarly, they may take data about your clients if you store confidential business data in the cloud.
Denial of Service Attacks
Denial of Service attacks remains one of the most frequent attacks that criminals use against websites. Interestingly, criminals can successfully stage this type of attack against a cloud storage service. This is what happens. Cybercriminals, using complex malware, can take charge of several computers. They then remotely command the computers to send a large number of requests to a single cloud storage service. The service, overwhelmed by fake requests for service, fails to deliver. In so doing, the criminals force the service to fail to serve genuine clients.
General security concerns
Many clients do not understand some of the most important safety of cloud storage services. For example, many clients do not bother to check how the cloud storage services keep the encryption keys. This is an important issue given that if a cloud storage service loses the keys to a rogue employee, you will end up losing your data. Alternatively, some cloud storage services allow their clients to keep their encryption keys. However, many clients do not understand the different security arrangements that cloud storage services offer them.
Employees of cloud storage services have access to a lot of insider information. In practice, cloud storage services take strict measures to prevent their employees from accessing secure client data. However, the possibility of rogue employees abusing internal procedures remains. An employee may abuse internal processes and release confidential customer data to the public. This may hurt both the clients and the cloud storage service.
