What is data security? In modern business, it is about securing critical information from getting into the wrong hands and ensuring all your company, employee, and customer data. Data breaches can have a devastating impact on businesses, especially those that handle sensitive information every day.

Read on to learn more about data security for businesses and why having a strong cybersecurity strategy is important in protecting that information.

The Definition of Data Security

Data security is defined as “the process of maintaining the confidentiality, integrity, and availability of an organization’s data in a manner consistent with the organization’s risk strategy,” by the National Cybersecurity Center of Excellence (NCCoE) brand of the Nation Institute of Standards and Technology (NIST).

This can happen in 3 stages: before, during, and after an incident takes place.

  • Before the incident: confirm that the security architecture and response plan are in place

  • During the incident: ensure the organization detects and responds appropriately

  • After the incident: verify that a plan is in place with the ability to recover effectively and efficiently

Data Storage’s Role in Data Security

The method by which this data was stored has changed over the years as well. From the humble beginnings of handwritten documents stored inside a file cabinet to data files on hard drives to the current cloud storage such as Microsoft’s OneDrive and Google’s Google Drive.

As technology has evolved, the policies and procedures were forced to keep up with cybercriminals attempting to steal sensitive data. This is now known as Data Loss Prevention.

Securing Paper-Based Data Storage

When data was stored in paper documents, the security process started with locked file cabinets. Later, obsolete documents were shredded (and then upgraded to cross shredding) to prevent documents from being stolen from the company garbage. At times, even the data disposal location was secured.

Data Security for Digital Documents

As technology advanced to storing data on hard drives, new ideas were needed. One of the first ideas implemented was file permissions, which allows only authorized people to view files. File encryption emerged next, which made data unintelligible without a cipher to decrypt it.

Cloud Technology and Data Security

As mobile technology surfaced, the adoption of biometrics, using physiological data to open or access files, increased. Most recently, cloud technology allows data to be stored at a data center via a third-party provider.

Why Data Security is Important for Modern Businesses

Understanding how data security works and its importance is vital for businesses in today's digital environment, regardless of size and scale.

About 52% of breaches are from a malicious attack, which had a combined direct and indirect average cost of $4.27 million.

Business Costs of a Data Breach

Besides the obvious pitfalls associated with losing critical business data, a data breach can result in many other costs, including:

  • Loss of production

  • Company trust erosion

  • Systems locked down with attackers demanding payment to remedy it (ransomware)

  • Stolen proprietary data like a blueprint or schematic that is in development or production

  • Possible fines for HIPPA violations to companies in the healthcare industry

  • Stolen company, customer, or employee data resulting in fraud or identity theft using stolen Personally Identifiable Information (PII)

Data Security Solutions for Businesses

Managed security services providers (MSSPs) like DOT Security offer a solution to help in all 3 stages: before, during, and after.

It begins with a Risk Audit to check a company’s current security situation. In addition to the risk audit, a Gap Analysis is often performed by compliance experts to determine if a company is still compliant with the necessary government regulations.

When both are done, cybersecurity specialists review the findings to determine the best course of action, including the protocols, software, best practices, and training necessary for your business to stay secure and protect its most valuable data, such as:

  • Access management to control who can access certain information

  • Encryption to secure who can view data and protect it during transfers and storage

  • Endpoint security to secure devices accessing the business network

  • Awareness training to help your staff understand cyberattacks and how to spot them

In Conclusion

With the increase of attacks and data breaches occurring, it is important that company, customer, and employee data all be protected. To do this, businesses need to establish a strong cybersecurity posture that includes cybersecurity best practices, software, and employee education on the importance of data protection.
