What is Data Security Management?

Data security management is the practice of safeguarding an organization's sensitive information against unauthorized access, breaches, data corruption, and other security threats. Managing data security typically involves a comprehensive strategic plan with policies, technologies, and risk management tools designed specifically to protect sensitive data.

Key Components of Data Security Management

Businesses that build and execute a plan for data management in cybersecurity plan are better able to reduce their risk of a breach, maintain stakeholder and customer trust, avoid litigation, and protect their reputation.

An effective cybersecurity data security management and control strategy includes the following elements:

• Access Control: Restricting data access to authorized personnel only.
• Data Encryption: Encoding data to prevent unauthorized access during storage and transmission.
• Network Security: Implementing measures like firewalls and intrusion detection systems to protect data during transmission.
• Incident Response Planning: Establishing protocols to address data breaches or security incidents promptly.
• Compliance and Auditing: Ensuring adherence to legal and regulatory requirements through regular audits.

Equally important, but somewhat more obvious is the need to use strong passwords, multi-factor authentication (MFA), and clearly define and communicate data security practices across the organization. This can be part of onboarding, but should also be reinforced or revisited at regular intervals with all departments that touch organizational and customer data.

Data Security Threats and Breaches: By The Numbers

Data security threats continue to evolve. According to the Identity Theft Resource Center’s (ITRC) 2024 Data Breach Report, in 2024 the most common data breaches that led to victim notices were:

• Cyberattacks: 1,229,866,035 victim notices
• System and Human Errors: 116,671,768 victim notices
• Physical Attacks: 189,354 victim notices
• Supply Chain Attacks: 203,144,092 victim notices

The global average cost of a single data breach in 2024 was $4.88 million, according to IBM’s Cost of a Data Breach Report 2024. That's compared to $4.35 million in 2022, a roughly 11% increase.

Let's explore just one data security policy we know has a track record of protecting organizations of all sizes against security breaches: multi-factor authentication.

Case Study: MFA for Data Security Breach Prevention

That ITRC report found at least 196 of the compromises that led to those victim notices could've been prevented with the addition of MFA to any of their legacy services. Specifically, the attacks against Ticketmaster, AT&T and Change Healthcare (a subsidiary of UnitedHealth) would've been prevented. Speaking before a Congressional Subcommittee, executives with Change acknowledged their attackers used stolen credentials from accounts not protected with MFA. Through those compromised accounts they gained access to the system.

"Change Healthcare was a relatively older company with older technologies, which we had been working to upgrade since the acquisition. For some reason, which we continue to investigate, this particular server did not have MFA on it." - UnitedHealth CEO Sir Andrew Witty testifying before the Oversight and Investigations Subcommittee in May 2024.

Data Security Policies and Compliance

Data Security Policies and Compliance help organizations protect sensitive data and maintain strong brand reputations.

Let's explore how three commonly referred regulations are specifically built with security and privacy in mind:

• General Data Protection Regulation (GDPR): A far-reaching, broad, and robust data security law protecting all EU citizens from data privacy breaches and data misuse.
• California Consumer Privacy Act (CCPA): Gives California residents more control and consumer rights over how businesses and organizations collect and handle their sensitive personal information.
• Health Insurance Portability and Accountability Act (HIPAA): Creates security measures to keep the protected health information (PHI) of consumers from unauthorized access or disclosure without a patient’s consent or knowledge.

Adhering to these data protection laws is crucial for organizations to protect sensitive data and avoid legal repercussions.

Cloud Data Security

Cloud Data Security is crucial for securing dynamic working processes as employees increasingly work from home. Cloud data security solution features include:

• Encryption
• Access controls
• Data loss prevention

These measures are essential for protecting sensitive data and preventing unauthorized access. According to a report by Cybersecurity Ventures, the global cost of cybercrime is expected to reach $10.5 trillion by the end of 2025.

This cost assignment shows the increasing importance of cloud data security in protecting sensitive information regardless of an organization's size or industry.

Keys to Resiliency: Data Backup

• Data backup: restores data in the event of a storage failure, data breach, or disaster.
• Real-time alerts: can automate notifications for potential data misuse, allowing for swift action to mitigate risks.
• Risk assessment: involves understanding who has information about your data and security practices, ensuring that only authorized personnel have access.
• Data auditing: addresses major concerns like data protection, accuracy, and accessibility.

Best Practices for Enhancing Data Security Measures

Organizations should adopt the following strategies to better manage data security:

• Implement MFA: Requiring multiple verification methods to access systems.
• Regularly Update and Patch Systems: Keeping software and systems current to mitigate vulnerabilities.
• Conduct Employee Training: Educating staff on security protocols and recognizing potential threats.
• Perform Regular Security Assessments: Identifying and addressing potential security gaps proactively.
• Develop a Comprehensive Data Backup Plan: Ensuring data recovery in the event of loss or corruption.

Developing a robust data security management strategy involves continuously monitoring for emerging threats and implementing a cyclical four-step process to manage risks effectively.

How Tailscale Improves Data Security Management Strategies

Tailscale works with your existing stack to improve your data security management strategies through several key features:

• Zero Trust Networking: Tailscale's policy engine operates in a least-privileged mode by default, requiring explicit permissions for users, devices, groups, and tags. This approach minimizes unauthorized access and strengthens security postures.
• Continuous Verification: By integrating with endpoint detection and response (EDR) systems like CrowdStrike, Tailscale continuously verifies device compliance, ensuring that only trusted devices can access the network. This continuous verification aligns with zero trust principles.
• Secure Access Controls: Tailscale allows dynamic management of user and group lifecycles through System for Cross-domain Identity Management (SCIM). It authenticates network access using Single Sign-On (SSO) and Multi-Factor Authentication (MFA), reinforcing access security.
• End-to-End Encryption: Using the WireGuard protocol, Tailscale makes sure all connections are encrypted end-to-end to protect data during transmission and maintaining confidentiality.
• Comprehensive Audit Logging: Tailscale provides streaming of configuration audit logs, network flow logs, and Secure Shell (SSH) session recordings into preferred Security Information and Event Management (SIEM) systems. This capability enhances monitoring and detection of anomalous activities.

By integrating Tailscale into your security infrastructure, organizations can effectively reduce their risk surface area, implement robust access controls, and maintain continuous verification of devices and users, thereby strengthening their overall data security management.
