Security Audit Checklist: 7 File Transfer Security Questions Every CISO Should Ask Before the Next Audit

File transfer security is no longer just an IT checkbox, it's mission-critical. In 2024, more than 70% of data breaches involved data in motion, often caused by unsecured file transfers between internal systems, partners or cloud platforms. When file transfer processes aren’t properly secured, auditors will quickly uncover the gaps. And in today’s increasingly strict compliance environment, that’s a conversation no CISO wants to have.

This article, developed for Global E-Director, serving organizations across the MENA region, explores the essential security audit checklist for file transfer systems. It highlights the key questions CISOs should be asking about file transfer security, practical steps to prepare file transfers for security audits and how solutions like Globalscape MFT help close critical security gaps with confidence.

What file transfers include

In modern enterprises, file transfer isn’t just FTP:

• API and automated system data movement

• Cloud uploads/downloads (AWS, Azure, Google Cloud)

• Email and attachments

• Secure Managed File Transfer (MFT) tools like Globalscape MFT

How insecure transfers increase risk

Data moving without encryption or visibility is like sending cash through the mail anyone can intercept it. CISOs need to lock down not just endpoints, but the paths data takes.

Why Auditors Focus on File Transfers

Compliance standards

Auditors evaluate file transfer security against key frameworks:

• ISO 27001

• SOC 2

• PCI DSS

• HIPAA

• GDPR

Across these, secure transfer, logging, access control and encryption are recurring requirements.

What auditors look for

Auditors won't just ask are file transfers secure? They want evidence:

• Encryption proof

• Logs showing transfers and recipients

• Policies governing file movement

Question 1 – Do We Have Full Visibility Into All File Transfers?

You can’t secure what you don’t see.

Shadow IT unauthorized tools used by teams remains a top risk. Even today, 45% of organizations report unmanaged file exchange tools in use.2

Globalscape MFT helps by offering centralized visibility into all file transfers, reducing blind spots and giving auditors clear oversight reports.

Question 2 – Are Our File Transfers Encrypted End-to-End?

Encryption isn’t optional, it's mandatory.

Secure protocols like TLS 1.3, SFTP and HTTPS ensure data is protected both in transit and at rest. Missing either is a compliance gap.

Question 3 – Who Can Access, Send and Receive Sensitive Files?

The principle of least privilege is key. Only authorized roles should transfer sensitive files.

Integrations with Identity and Access Management (IAM) tools (e.g., Active Directory) make sure roles and rights are properly enforced.

Question 4 – Are File Transfers Logged, Tracked and Auditable?

Immutable logs are non-negotiable. Auditors want:

• Who sent the file

• When it was sent

• Where it went

SIEM tools tied to file transfer logs make this audit-ready.

Question 5 – How Do We Handle Third-Party and Vendor File Transfers?

Vendors often have weak security controls. Using unencrypted email or FTP for third-party exchanges is a red flag.

A secure MFT like Globalscape MFT replaces insecure methods by offering encrypted transfer with partner authentication.

Question 6 – Can We Detect and Respond to Suspicious File Transfer Activity?

Anomaly detection is more than logging. It’s about alerts when something unusual happens like large outbound transfers after hours.

Integration with monitoring platforms helps CISOs and security teams respond fast.

Question 7 – Are Our File Transfer Policies Documented and Enforced?

A policy that isn’t enforced is useless. Auditors will ask for:

• Written policy documents

• Evidence of training sessions

• Enforcement controls in place

Regular awareness programs reduce user-caused risks.

File Transfer Risk Comparison

File Transfer Method	Visibility	Encryption	Auditability	Risk Level
Email Attachments	Low	None	None	High
FTP (Legacy)	Low	Weak/None	Poor	Very High
Cloud Share (Ad-hoc)	Variable	Partial	Partial	Medium-High
Secure MFT (e.g., Globalscape MFT)	High	Strong	Strong	Low

How to Build a File Transfer Security Audit Checklist

Elements to include

Your security audit checklist should cover:

• Inventory of systems

• Encryption standards

• Logging and SIEM integration

• Vendor/partner transfer controls

• Access control

• Policy documentation

Mapping to audit frameworks

Align each item with frameworks like ISO 27001 and SOC 2 to ensure auditors see traceable control mappings.

Secure File Transfer Features Checklist

Checklist Item	Required	Audit Evidence
End-to-End Encryption	Yes	Config logs, protocol settings
Centralized Transfer Monitoring	Yes	Dashboard screenshots, reports
Access Control Policies	Yes	IAM configs, role definitions
Vendor Transfer Controls	Yes	Secure partner integrations
Anomaly Detection & Alerts	Preferred	SIEM alerts, incident logs
Training & Policy Acknowledgment	Yes	Attendance records, signed policies

How to Prepare File Transfers for Security Audits

Pre-audit self-assessment

Conduct mock audits:

• Check logs for gaps

• Verify encryption protocols

• Ensure policies are up to date

Common mistakes to avoid

• Assuming email is secure

• Ignoring ad-hoc transfer tools

• Not updating encryption protocols

How Globalscape MFT Helps Improve Security

Globalscape MFT is more than a secure tool, it's a compliance partner. Key advantages include:

• Centralized dashboard for all transfers

• Enterprise-grade encryption

• Automated logging and reporting

• Vendor and partner secure exchange

• SIEM and IAM integration

With Globalscape MFT, CISOs can simplify how to prepare file transfers for security audits producing auditor-ready reports in minutes, not weeks.

Conclusion

Preparing for your next audit doesn’t have to be stressful or disorganized. By asking the right questions about file transfer security and leveraging purpose-built solutions like Globalscape MFT, CISOs can move beyond basic compliance and build true security maturity.

For Global E-Director, serving organizations across the MENA region, a strong security audit checklist combined with proactive preparation and the right technology transforms audits from high-pressure exercises into confidence-building milestones that strengthen long-term security posture.
