What is Data Security - Types, Strategy, Compliance and Regulations

What is Data Security?

Why is Data Security is so important? We are living in the age of the Data Revolution, and every aspect of our lives has turned out to be data-driven. Just by controlling data, one can control institutions, organizations, and even governments. Today, we have access to a large amount of data, the means to store it, and the ability to read it and draw insights. But what if such crucial data falls into the wrong hands? And what if the data is corrupted or lost?

And that is why Data Security is so important.

Data security is the process of safeguarding sensitive digital information from unauthorized access, corruption, and theft throughout the data lifecycle.

This includes every aspect of information security, such as the physical security of the hardware and storage devices for the data, the security of the software application, and organizational policies and regulations.

This means the data will be protected against attacks by criminals who will encrypt or modify it. Data leaks will be prevented, and we will ensure that the data is easily accessible for authorized personnel.

Data security and robust cybersecurity strategies are very important for any organization to protect itself from cybercriminal activities. It also safeguards against insider threats and human error, which are regular occurrences in large organizations handling a large amount of data.

The data security concept involves using tools and technologies to handle critical data and provide protection for it through encryption, data masking, redaction of sensitive files, and so on.

 

Why is Data Security Important?

Studies show that on average, a country like the USA suffers a loss of 8 million USD due to data breach issues. 25,000 user accounts are impacted due to data violations. These incidents are more than financial losses; a data breach leads to a loss of customer trust and damages the reputation of the organizations. And below are a few other important reasons why data security is crucial.

Importance of Data Security

☑ Governments around the world are introducing stringent rules and regulations surrounding data privacy. This enables the user with more rights, and if unforeseen events may occur, with these rights, the user can file lawsuits against organizations, resulting in fines and settlements.

☑ Data criminal activities like social engineering, ransomware, and advanced persistent threats are on the rise. These threats are extremely difficult to counter and are capable of wreaking havoc on an organization’s data.

☑ Companies are expected to take up additional standards set by industry regulators if the nature of the data they deal with is highly sensitive. For example, organizations dealing with credit card transactions are expected to adopt PCI/DSS (Payment Card Industry Data Security Standards).

 

What is the difference between Data Security, Data Protection, and Data Privacy?

While all these names do sound similar and they deal with securing data, they do have a distinct function. Let us discuss each of these measures in detail.

☑ Data Security – Data security is a measure to protect your data against unauthorized access, loss, and encryption. For example, encrypting your data so that the hackers won't be able to use it

☑ Data Protection – This is the process of creating backups or duplicates so that you’ll be safe from accidental erasure or deletion. Using a cloud backup is one of the data protection methods; here, even if the hardware containing the data is lost, the data will be secure in the cloud.

☑ Data Privacy – Data privacy involves the collection and usage of data concerning the regulation and consent of the users. Website cookies are one of the best examples of data privacy where the user’s permission is requested to collect data.

 

What are the different types of Data Security?

There are a lot of data security measures to protect sensitive information, here, let us discuss the most commonly used types.

Data Security Types

Encryption

Data Encryption is the process of translating plaintext (unencrypted) to ciphertext (encrypted). If the user needs to access encrypted text, they need an encryption key, and to access decrypted text, they need a decryption key.

In other words, encryption means coding data mathematically so that it can only be read or decrypted by someone with the correct key or cipher. Digital encryption renders digital information unreadable to unauthorized users with the help of algorithms.

Data Masking

Data Masking is one of the most important types of data security methods; it is achieved by hiding the original data with modified content. Data masking involves interchanging some elements of the data, which would enable the security and confidentiality of the information.

There are several kinds of data masking techniques, like static data masking, deterministic data masking, on-the-fly data masking, etc.

Data Resiliency

Data Resiliency is the ability of a network, server, or even an entire data center to recover quickly and continue operating even if there is any equipment failure, like a power outage, system issues, or other disruptions. Organizations need to have efficient methods to counter any hardware malfunction that would affect data availability. The speed of the recovery is very important to minimize the impact.

Data Erasure

Data Erasure also referred to as data clearing or data wiping, is a software-based method of overwriting the data to destroy all the electronic information in the device or the digital media. It is usually done by overwriting zeros and ones on all the sectors of the device.

You can achieve data sanitization by overwriting data on the storage device, which would render the data irrecoverable.

 

What are the different Data Security Solutions?

It is common knowledge that organizations today use a vast amount of data in various forms. And this data is highly complex, distributed, and stored in a multi-cloud environment. It is very challenging to work with such a data system.

Especially understanding where the data resides, tracking the usage, monitoring file movements, and mitigating the risk involved in them. 

Data security solutions offer organizations a systematic approach to monitoring and streamlining these tasks.

And below are some of the data security solutions.

Data Security Solutions

☑ Data classification tools – sensitive information can reside in both structured and unstructured forms in databases like a data warehouse, big data platform, and cloud. Data discovery and data classification tools will help in identifying sensitive data and assessing the risk associated with it. It will also automate the process so that it can be applied across all the data platforms.

☑ Data activity monitoring – using this method, you can analyze the pattern of the data and file usage. You can continuously monitor who is using the data and spot any outliers. You can automate it to block access to the data when an anomaly is spotted.

☑ Vulnerability and risk assessment tools – there are a lot of risks and vulnerabilities involved in the software and technology we use, and sometimes they can escape our attention. This resource will help you identify risk factors like outdated software, misconfigurations, weak passwords, etc. It can also detect the data source’s risk of exposure. And ensure Database security.

☑ Compliance reporting – security compliance is a big part of data security solutions; organizations have to comply with the guidelines of regulatory bodies, and failing to do so will incur hefty fines. This solution will track any compliance issue and alert you to any deterrents to timely correction.

 

Data Security Strategy

So far, we have discussed the need for data security systems and different types of data security solutions. In the following section, let’s dive deep into different types of data security strategies. The main components of a data security strategy are people, processes, and technologies.

Information security cannot be achieved just with tools and technologies. At the end of the day, it’s the people who work on them, and hence organizations should make information security a top priority and infuse it into their organizational culture.

Physical security of servers and devices – irrespective of whether you have in-house data storage or third-party data storage, security facilities are required to protect devices housing your data. It needs to be fully equipped against any intrusion, fire, and other factors.

Access and control management – there is a commonly used principle followed in most organizations when it comes to data handling known as ‘least privilege access’. Which means the information needs to be handled by as few people as possible. And access needs to be granted only on the basis of the highest requirements.

Application security – all the software applications used should be updated to the latest version, and need to be continuously monitored so that there is no outdated software in use.

Backups – a robust data security strategy must be able to counter any unforeseen challenges, even ones like data losses. Thoroughly tested copies of all critical data must be saved. And these backups should be subjected to the same physical and logical security guidelines.

Employee awareness – there are numerous instances of security breaches due to human negligence; hence, employees must be trained on information security. From following hygienic password practices to spotting social engineering attempts, awareness among the people working with the data can greatly aid data security.

Network and endpoint security monitoring – risk management, detection, and response tools should be employed across the platform. This will mitigate the risk of a potential data breach.
