Data security in cloud computing is a set of policies, tools, procedures and technologies that used to protect customer’s data, applications and networks. In this post, we will discuss on what is data security in cloud computing.

What is Data Security in Cloud Computing?

What is data security in cloud computing? Data security in cloud computing is the process of protecting the data from cyber threats or unauthorized access. It ensure the data confidentiality, integrity and availability of data that an organization store and access.

Data security is very important for both cloud service providers and clients. Here are some useful tips to keep your data safe and secure in cloud computing.

1. Use Strong Password

The first thing you have to create and use a strong password which can protect data from hacking. Never use simple password to remember in mind such as date of birth, mobile no, employee id, student id, test123, 123456. However, here are some tips to create a strong password:

  • The password length should be at least 10 characters long.
  • The password doesn’t contain your user name, real name, company name or institution name.
  • The passwords should contain uppercase letters (A – Z), lowercase letters (a – z), numbers (0 – 9), and special character (@, #, $, %, ^, (,), &, *!).
  • Example for strong password:C#a25^ub@2 is a strong password and standard password

It is strongly recommended to you that use strong and unique passwords for different account and change your password regularly, usually between 30 and 180 days.

2. Data Encryption

Data encryption is one of the best ways to ensure data security in cloud computing. It provides the more security of your data because you need to decryption before accessing the data. This decryption process will protect data against service providers and unauthorized users also.

There are different types of encryption methods such as AES, MD5, and SHA 1 are used to encrypt and decrypt the data.

3. Antivirus Software

Antivirus is a program that helps to protect malware, viruses, and unwanted threats on your cloud data and prevent hackers from unauthorized access of your data.

If you expose yourself to malware and viruses then hackers can easily access your system. So, you have to use very effective anti-virus software for your system, which will protect all kinds of files and information.

You should use a professional anti-virus software to secure your data in cloud computing, which are as follows:

4. Data Integrity

Data integrity gives the guarantee that data is in correct format, ensure quality, and protecting data from unauthorized modification or deletion.

When user storing data to the cloud, they think cloud service providers are providing reliable services to them and hopes that their data are in secured way. But it is true that the cloud service providers may be unfair and user’s data may be altered or deleted by them and also may discard the data which has not been accessed by user’s.

So, data integrity is one of the major concerns with cloud computing data storage.

5. Inside Malicious

Malicious insiders are the people who are authorized to manage the user’s data or who have access to the data such as database administrators, partners, and contractors of the cloud services company.

They are doing illegal activities such as they can steal or corrupt the data whether they are getting paid by other companies. In that case, cloud service providers may not be aware of that issue because of their inability to properly managing their employees.

To prevent from inside malicious attack cloud service provider can “create a system to notify them when data breaches happen”.

6. Denial of Service Attack

Data availability is a process which ensuring the data is available for uses anytime whenever needs it. It is very important for some company because they are providing critical services so, their systems to be available all the time.

In cloud services system, resources are shared by many clients. In that case, if an attacker uses all available resources then others cannot use those resources, as a result data will be unavailable which lead to denial of service attack. Sometimes could slow accessing those resources.

7. Data Loss

There are many ways to lose data in the cloud computing system such as technology fails, backup copies are lost, and servers’ crash. However, the most common factors for data loss in the cloud are as follows:

  • Accidental Deletion
  • Malicious attack
  • Overwriting Data
  • Data encryption
  • Data backups and Recovery

To protect losing the data, here are the some important tips:

  • Use a strong API between the cloud service provider and the client where clients can manage and control their data.
  • Use data encryption technology for data storage in cloud
  • Specifying the backup and recovery strategies

Conclusion

Finally, as a cloud service provider you should ensure the data security in cloud computing. We have discussed the topics What is data security in cloud computing. Hope the article will be helpful for you.
