This not only helps maintain customer trust and confidence but also provides a competitive advantage by enabling organizations to protect intellectual property, meet compliance requirements and improve efficiency.
7. Avoids Additional Costs
Data breaches may be costly for businesses, necessitating additional investments to address the consequences and build a more robust infrastructure to protect data in the future. Ensuring a safe and secure infrastructure from the beginning prevents these additional costs.
Three Elements of Data Security
Confidentiality, integrity, and availability (CIA triad) are three data cybersecurity pillars:
- Confidentiality ensures that only authorized users with the required credentials can access confidential data.
- Integrity ensures the stored data is reliable, accurate, and not subject to unwarranted changes.
- Availability ensures data is accessible for businesses promptly and securely.
Five Data Security Best Practices
- Provide Cybersecurity Training
- Ensure Data Security Compliance
- Craft a Thorough Strategy
- Strengthen Protocols and Response Plans
- Reach Out for Professional Help
Data security best practices can improve your existing security strategy, prevent data breaches and help with overall business management:
1. Provide Cybersecurity Training
Cybersecurity training provides individuals or teams with knowledge and skills to protect digital devices, networks, and sensitive data from cyberattacks. It can cover cyber threats, security protocols, data protection, and incident response topics.
Cybersecurity training aims to raise awareness of cyber threats and provide the tools and knowledge to recognize, prevent and respond to potential security incidents. If your in-house team handles security matters, you must train them to protect sensitive data most effectively.
Without cybersecurity training, the teams’ performance will also be limited, increasing the risk of data breaches. Another option is to hire a cybersecurity company to help you keep valuable data safe from malicious activities.
2. Ensure Data Security Compliance
Organizations must adhere to guidelines such as PCI DSS, HIPAA, GDPR-General Data Protection Regulation, the California Consumer Protection Act (CCPA), and the Sarbanes Oxley Act (SOA). Data discovery and categorization tools can help find regulated data to protect cardholder information with relevant security measures.
Many compliances require regular assessments, including:
- Identifying potential hazards
- Checking possibilities and impact of potential hazards
- Implementing measures for risk assessments
- Evaluating the success measures of the implemented tactics
3. Craft a Thorough Strategy
A well-rounded data security strategy should incorporate administrative, technical, and physical controls, such as policies, processes, and IT security measures. This should also include regular data backups in all formats to ensure data can be recovered in case of an unexpected event.
Moreover, a comprehensive strategy should also facilitate secure data collaborations. For instance, when sensitive information is shared via email, it is recommended to establish a digital rights management system or use another secure email solution to prevent unauthorized access. Checklists and a robust standard framework can also help achieve these goals.
4. Strengthen Protocols and Response Plans
Cybercriminals constantly improve their attack strategies, making it crucial for businesses to implement stronger security protocols to prevent these threats.
Consistent team penetration testing and automated monitoring are effective techniques that can help organizations avoid potential threats. Cyber-threat awareness training is also essential to help employees understand how to recognize and mitigate risks. Prevention measurements also include storing backups in independent data systems and regular compliance audits, which can identify weaknesses or loopholes in the system.
By investing in these practices, organizations can minimize the risks of cyber-attacks and protect sensitive data from being compromised.
5. Reach Out for Professional Help
If organizations don't have in-house security teams, they should seek professional help. External advisors can provide valuable insights into current government laws and regulations and assist with making significant shifts in the organization's security strategy. Moreover, penetration testing companies can simulate cyberattacks to discover vulnerabilities and help you develop appropriate defensive strategy.
Another safe practice is consistently transferring data to a reliable and trustworthy location to ensure its protection. By implementing these measures, organizations can strengthen their security posture and better safeguard sensitive data against threats.
Seven Types of Data Security
- Access Control
- Disaster Recovery and Backups
- Data Resiliency
- Data Masking
- Data Erasure
Organizations can practice data security in different ways. They are as follows:
1. Access Control
Access control refers to limiting physical and digital access to the central system. Computers and gadgets are protected through a mandatory login, and entry to physical spaces is restricted to authorized personnel only.
Authentication refers to accurately identifying users before they access data. It requires access restrictions and correct identification: passwords, PINs, swipe cards, tokens, and biometrics.
3. Disaster Recovery and Backups
Regular backups can significantly reduce the impact of data breaches, system failures, data corruption, and disasters. Restoration requires a backup stored in a different format, such as a hard drive, physical disk, cloud, or local network.
4. Data Resiliency
Data resiliency refers to the speed and accuracy of an organization in bouncing back after a cyberattack. It may also be demonstrated during power shortages, hardware attacks, or other cases that affect data integrity and availability.
5. Data Masking
Data masking obscures sensitive data using proxy characters, keeping them private and unreadable even if hackers gain unauthorized access. It enables development and training using real data while protecting Personally Identifiable Information (PII) and ensuring compliance. Authorized users can revert the data to its original state.
6. Data Erasure
Appropriate data discarding is more secure than standard data wiping. It uses software to overwrite data on any storage device completely. Data erasure also ensures that data cannot be retrieved and doesn’t land in the wrong hands.
Encryption uses an algorithm to transfer standard text characters into an unreadable format. It scrambles data for only authorized users to unlock and access the information.
