Data Security Standards: Key Regulations, Compliance, and Implementation Tips

We live in a place where each day millions of data get stored and managed by organizations. This includes your account details, email, messages and transactions. In order to protect the digital data, businesses must follow the data security standards to create tailored strategies and solutions against cyber attacks.

In this blog, you will get to know the widely used data security standards and how businesses can follow them to safeguard their data.

What Are Data Security Standards?

Data security standards are certain rules and guidelines created by government, international organizations, and industry groups for data protection that must be followed by organizations.

Data security standards are applied to almost every industry, like banks, hospitals, and e-commerce, which guides them to securely collect and store their customer data. Industries following these standards can reduce the risk of data breaches.

Key Data Security Regulations You Should Know

PCI Data Security Standards (PCI DSS)

PCI data security standards are globally followed to protect the cardholder details during transactions. The PCI Data Security Standards were developed in 2004 by top card companies, including Visa, American Express, and Mastercard.

Following are the 12 requirements under the PCI DSS:

1. Installation and maintenance of firewalls
2. Don’t use vendor-supplied defaults for security parameters
3. Safeguard cardholder details
4. Encryption of data across private and public networks
5. Use of antivirus software and solutions
6. Regular update of security systems
7. Only authorized user can access the data
8. Each user must get a unique ID to access the account
9. Secure storage of transactional data
10. Keep track of all access to network resources and cardholder data
11. Regular scans of security systems
12. Support data security with policies and programs

By following these requirements, businesses can comply with PCI DSS. On the other hand, non-compliance can lead to heavy penalties.

ISO Data Security Standards 27001 (ISO)

ISO includes internationally approved standards that help businesses in building a strong information security system (ISMS). As of now, there are over 25,000 standards covered in the ISO. Among these standards, ISO 27001 is one of the most certified standards when it comes to cybersecurity.

Here’s how a business can become ISO 27001 certified:

• Get management support and budget
• Decide what parts of the business to cover
• Find and list your security risks
• Plan how to fix or reduce those risks
• Write down your security policies and rules
• Put the security measures in place
• Train your employees on security
• Run the system for a few months to show it works
• Check yourself with internal audits
• Fix any gaps found
• Hire an approved external auditor
• Pass the document review (Stage 1)
• Pass the on-site check (Stage 2)
• Do yearly check-ins to keep the certificate

With an ISO certification, businesses can improve the trust of their partners and customers.

General Data Protection Regulation (GDPR)

The General Data Protection Regulation (GDPR) is passed by the European Union (EU) and focuses on maintaining the data privacy and security of the European users. It is to be noted that this law is applied to any organization that holds the data of EU citizens.

Here are the rules that businesses must follow under GDPR:

• Ask for clear consent before collecting any personal data
• Tell users exactly what data is being collected and why
• Collect only the limited data needed for the stated purpose
• Allow users to access their personal data whenever they want
• Allow users to correct any inaccurate data about them
• Allow users to request deletion of their data
• Allow users to transfer their data to another service provider
• Report any data breach to the relevant authority within 72 hours
• Appoint a Data Protection Officer (DPO) if processing large amounts of sensitive data
• Ensure third-party vendors and partners also comply with GDPR rules
• Do not use personal data for any purpose beyond what was originally stated
• Store personal data only for as long as it is needed
• Implement strong technical and security measures to protect personal data
• Maintain clear records of all data processing activities
• Get parental consent before collecting data from children under 16

Companies that don’t follow these rules are penalized up to 20 million euros or 4% of their global revenue earned.

How Businesses Can Implement Data Security Standards

Limit Access Control

Businesses should implement role-based access and permission to make sure that only specific people can access the data.

Data Encryption

Data must be encrypted at both rest and transit to avoid any breaches. Moreover, using key management solutions can help securely store the encrypted data.

Use Security Tools & Solutions

Install security tools like firewalls and antivirus along with cybersecurity solutions like the HSM modules.

Train Your Employees

Human error is a common mistake that causes data breaches. Therefore, employees must be trained and aware of cybersecurity practices to avoid cyber attacks.

Conduct Regular Security Audits

There should be a regular check of security systems to find any vulnerable spot and fix it before hackers can exploit it.

Work With a Trusted Technology Partner

Businesses can also partner with a reliable cybersecurity company, like AppleShineTech, that can help them understand their security needs and provide catered solutions.

Conclusion

In conclusion, every business must adhere to these rules, as protecting their customer data is not only a legal requirement but also a major responsibility.

Following these key data security standards like the PCI DSS, ISO and GDPR can help protect businesses from various cyber threats like data breaches, identity theft and financial fraud.
