What is Data Security? | Best practice for Data Security

In general, we carry a lot of data in our daily lives; data is what gives information its meaning and value. Data security involves defending data from unauthorized internal and external use. Data security refers to the procedures and tools used to safeguard private and sensitive data from unauthorized access, use, disclosure, disruption, alteration, and destruction.

It is significant because it contributes to the protection of data’s integrity, availability, and confidentiality, all of which are crucial for both people and businesses. Take the necessary precautions to secure data because failing to do so can result in monetary loss, harm to one’s reputation, and even legal culpability.

Why data security is important? | What is the purpose of data security?

If the wrong hands get into contact with the data, information about your personal and professional lives could be exploited against you.

The data may contain priceless information such as trade secrets belonging to your business or personal information like your Social Security number, tax identification number, date of birth, and passport number.

Data-security is a constant concern, but using encryption is one technique to lessen the likelihood that the data will be abused or fall into the wrong hands.

There are numerous techniques to specify and encrypt data in one’s own style so that it can be utilized simultaneously and decrypted as needed.

Now that encryption is a feature of the operating system, users may go there and encrypt data according to their capabilities.


Data Security Council of India and other countries

Everyone wants to protect their data, thus there are various organizations that periodically set policies and phrases that describe how to do so. One of these organizations is the council.

A data security council was established by NASSCOM in India to provide guidelines for data-security and privacy. In similar ways, many countries have their administrative body for data handling and that is the council body.


Data security in cloud computing

Nowadays, as cloud adoption rises, it is equally critical to secure cloud data. Any cloud provider, including Google, Microsoft, and Amazon Web Services, is acceptable.

Although it’s unlikely that cloud service providers will be primarily responsible for data-security, they do offer the bare minimum of security as a common technique.

The mechanism adds various pricing with distinctive characteristics, allowing customers to adopt and secure their data in cloud computing, although all cloud service providers enable consumers to adopt a good data-security system tool.

By implementing a web application firewall (WAF) one can protect data from web servers and services.


Data security and privacy

data security, data privacy

Data privacy and data security are slightly different concepts.

Data must be secured against both internal and external attackers during the data security process.

The primary variables in the data privacy process are data governance concerns with usage limitations and control and data collection.


Data security is a common risk of cloud computing

Risks of Cloud Computing


When data is stored on the cloud, its custodian is in charge of keeping it secure. However, the owner can also choose whether they wish to use a global standard security layer to protect the data or stick with the custodian’s normal method of doing so.

because access to the data can be made over the Internet or through a private ISP link in a secure manner. When data is accessed over a private, secure link, it is safe; nevertheless, using data in cloud computing is frequently risky when data is accessed over the public Internet.


Data security and storage in cloud computing | Data security in cloud computing


The amount of the data is always taken into consideration when processing it for security by the owner because it varies and depends on the business. Customers purchase storage space in the cloud computing system based on the size of the data.

In cloud computing, one can choose the level of data-security they want, and the data can be made fully or partially encrypted to make it secure.


Data security in DBMS; Database security

The database management system is referred to as DBMS.

Because data is stored in the database in the form of tables and records, it is essential to secure the data when using the database. However, not all users that access the database will necessarily need to use all of the tables.

Bifurcating the accessibility of the data with internal and external users and adequate access procedures is a recommended practice when adding effective data security to the DBMS.


Data security in Salesforce

Any business using CRM is holding data and information about their customers, vendors, and partners in Salesforce, which is a repository for data relating to customers and their relationships with them.

The data could be abused or utilized by a rival if it falls into the wrong hands, which would be bad for the company’s bottom line.
