Key Questions for a Cybersecurity Gap Analysis in Data Protection

How to Conduct a Zero Trust Data Gap Analysis

Is your data truly secure? A Zero Trust Data Gap Analysis helps organizations identify vulnerabilities, strengthen compliance, and prevent breaches before they happen.

✅ What data do you have, and where is it stored?
✅ Who has access, and is it properly restricted?
✅ Is sensitive data encrypted at rest, in transit, and in use?
✅ Are you meeting regulatory requirements like OMB, FISMA, and CISA?

Our latest blog breaks down the key questions every organization should ask to assess their cybersecurity posture and close critical gaps.

Zero Trust Data Gap Analysis – Annotated Key Questions

When conducting a Zero Trust Cybersecurity Gap Analysis for Data Protection, organizations must ask why each question matters and what potential answers reveal. 

Below is an annotated list of key questions with explanations:

1. Data Discovery & Classification

📌 Why This Matters: Data cannot be protected if an organization doesn’t know what data it has, where it is stored, or who has access to it. Classification helps prioritize protection based on sensitivity and regulatory needs.

✅ Key Questions & Implications:

• Do we have a comprehensive inventory of all sensitive data (PII, PHI, financial data, Controlled Unclassified Information,  proprietary information)?
  ➡️ If no: There’s a risk of unprotected sensitive data, increasing the chance of regulatory non-compliance and breaches.

• Have we classified data based on sensitivity, regulatory requirements, and business value?
  ➡️ If no: All data is treated the same, leading to inefficient security spending and increased risk exposure.

• Do we track where data is created, stored, processed, and transmitted?
  ➡️ If no: Shadow IT and data sprawl make it harder to detect leaks, breaches, and compliance violations.

• Can we automatically detect and classify sensitive data across on-prem, cloud, and SaaS environments?
  ➡️ If no: The organization is likely blind to where sensitive data resides, making it vulnerable to unauthorized access.

2. Access Controls & Identity Management

📌 Why This Matters: Unauthorized access is a leading cause of breaches. Zero Trust enforces least privilege access and ensures continuous authentication.

✅ Key Questions & Implications:

• Do we enforce role-based access control (RBAC) and least privilege principles?
  ➡️ If no: Employees or systems may have unnecessary access to sensitive data, increasing insider threats.

➡️ If yes: Do you also consider data attribute based control? E.G. what kind of data is it and who shouldhave access to it.

• How do we manage and secure privileged accounts?
  ➡️ If poorly managed: Attackers can escalate privileges, move laterally, and exfiltrate data.

• Is multi-factor authentication (MFA) required for all users, especially for accessing sensitive data?
  ➡️ If no: Phishing attacks or credential theft could easily lead to unauthorized access.

• Are third-party vendors and contractors restricted in their access to critical data?
  ➡️ If no: Vendors may introduce supply chain risks, as seen in breaches like SolarWinds.

• Do we have just-in-time (JIT) access to reduce long-standing privileges?
  ➡️ If no: Standing access increases the risk of maliciously using stolen or compromised credentials.

3. Data Encryption & Protection

📌 Why This Matters: Encryption ensures that even if data is stolen, it remains unusable.

✅ Key Questions & Implications:

• Do we have Data Loss Prevention (DLP) solutions in place?
  ➡️ If no: There's no way to detect, block, or respond to data leaks in real-time.

• Is all sensitive data encrypted at rest, in transit, and in use?
  ➡️ If no: Data is exposed at various points, making it a target for attackers.

• Are we using strong encryption standards (e.g., AES-256, TLS 1.2/1.3)?
  ➡️ If no: Weak encryption can be broken, exposing data to threats.

• How are encryption keys managed—are they stored separately from the encrypted data?
  ➡️ If keys are stored together: Attackers can steal both data and the keys to decrypt it.

• Do we enforce geofencing or jurisdictional controls for data sovereignty compliance?
  ➡️ If no: Sensitive data may be subject to foreign laws, increasing compliance risk.

4. Cloud & Third-Party Security

📌 Why This Matters: Cloud breaches are not always the provider’s fault—companies must protect their data in shared environments.

✅ Key Questions & Implications:

• Are we following the shared responsibility model for cloud security?
  ➡️ If no: Organizations may assume cloud providers handle security beyond their actual responsibility.

➡️ If yes: Do we have a clear idea of who is responsible for data security throughout its lifecycle.

• Have we assessed the security posture of third-party vendors who handle our data?
  ➡️ If no: Vendor breaches (e.g., MOVEit attack) can expose sensitive data.

• Are API security controls in place to prevent unauthorized data access?
  ➡️ If no: APIs may allow attackers to bypass traditional security defenses.

• Do our contracts with cloud providers include data security and compliance SLAs?
  ➡️ If no: The organization may have no legal recourse in a cloud data breach.

5. Endpoint & Network Security

📌 Why This Matters: Remote work, BYOD, and unmanaged endpoints increase the attack surface for ransomware and data exfiltration.

✅ Key Questions & Implications:

• Do we have endpoint detection and response (EDR/XDR) in place?
  ➡️ If no: Organizations lack real-time visibility into endpoint threats.

• Are network segmentation and micro-segmentation implemented?
  ➡️ If no: Attackers can move laterally unchecked inside the network.

• How do we prevent data exfiltration through USBs, email, or unapproved cloud storage?
  ➡️ If no: Sensitive data may be leaving the organization without detection.

6. Incident Response & Data Breach Preparedness

📌 Why This Matters: Delays in breach response increase financial losses and regulatory penalties.

✅ Key Questions & Implications:

• Do we have a data breach response plan with defined roles and responsibilities?
  ➡️ If no: The organization will scramble to respond when a breach happens.

• Are we meeting regulatory requirements for breach notification (e.g., NIST, FINRA, FISMA, GDPR 72-hour rule, CCPA, HIPAA)?
  ➡️ If no: Many regulations have limits on when a breach needs to be reported after occurring. The company could face major fines and legal action. 

• Do we have immutable backups to protect against ransomware?
  ➡️ If no: Recovery may not be possible without paying a ransom.

• Do we have controls in place for data exfiltrated during a ransomware attack when the attached has the admin credentials?

➡️ If no: We are open to ransomware extortion since the hacker has our data and we have no control over it.

7. Compliance & Regulatory Alignment

📌 Why This Matters: Failing to comply with GDPR, CCPA, HIPAA, FISMA,CISA,  NIST 800-171 can result in huge fines and reputational damage.

✅ Key Questions & Implications:

• Do we conduct regular compliance audits and risk assessments?
  ➡️ If no: Gaps may exist that could result in penalties.

➡️ If yes: Do they address data level controls inside and outside the network?

• Are employees trained on data privacy regulations and security best practices?
  ➡️ If no: Human error remains the biggest attack vector. Automation for data access control can limit this.

8. Data Governance & Lifecycle Management

📌 Why This Matters: Who should access which data, where, and when is part of governance. As is a chain of custody for sensitive data. Data should be retained only as long as necessary to minimize risk.

✅ Key Questions & Implications:

• Do we have a data retention and disposal policy?
  ➡️ If no: Unnecessary data hoarding increases the attack surface.

• How do we track who has access to data and how it is used?
  ➡️ If no: There is no way to audit misuse or unauthorized access.

9. Financial & Legal Costs of Data Loss

📌 Why This Matters: Understanding potential financial exposure helps justify security investments.

✅ Key Questions & Implications:

• What is the expected financial or legal cost of a major data breach?
  ➡️ If unknown: The organization may underestimate risks and underfund security. The industry average is $2.73 million.

10. Cyber Insurance 

📌 Why This Matters: Many organizations assume their cyber insurance policy will cover them after a breach—but most policies have major exclusions. 🔍

✅ Key Questions & Implications: Cyber Insurance: Are You Really Covered?

Research from Sophos shows that 99% of companies filing cyber insurance claims report their policies failed to cover all recovery costs. The primary reason for this shortfall is that total recovery expenses exceed policy limits.

🔹 What’s Often NOT Covered?
❌ Human error (if security best practices weren’t followed)
❌ Nation-state cyberattacks (considered “acts of war”)
❌ Ransomware payments (some policies limit or deny coverage)
❌ Regulatory fines & non-compliance penalties
❌ Data exfiltration (if no proof of misuse is found)

✅ How to Protect Your Business
🔐 Implement Zero Trust Data Security—encrypt sensitive data so even if stolen, it’s useless.
📜 Review your policy—ensure it aligns with your security posture.
🛡️ Strengthen DLP & access controls to minimize risks insurers won’t cover.

Time to rethink your cyber insurance strategy.
