Security Concept for PDF Annotator

Introduction

At PDF Annotator, we understand the importance of security in modern software development. Our customers trust us to deliver a reliable and secure tool to manage and edit PDF documents. To honor this trust, we have implemented a comprehensive security framework designed to ensure that our software and business operations are protected against threats. Below, we outline the steps we take to safeguard the integrity, confidentiality, and availability of our product and infrastructure.

PDF Annotator is an on-premise software application, meaning all processing and data management occur locally on the user’s device. Unlike SaaS applications, we do not transfer or store any user data on external servers. This approach ensures that sensitive documents remain under the full control of our users, eliminating risks associated with cloud-based storage and transmission.

1. Secure Development Lifecycle (SDLC)

1.1 Code Review and Quality Assurance

• All code changes undergo peer review to ensure they meet security and quality standards.
• Automated static code analysis tools are employed to identify potential vulnerabilities, such as buffer overflows, injection risks, and insecure code patterns.

1.2 Dependency Management

• Third-party libraries are regularly audited for known vulnerabilities.
• We use tools to monitor dependencies for security updates and patches, applying them promptly when needed.

1.3 Testing

We conduct rigorous testing, including:

• Unit tests
• Integration tests
• Regression tests
• Fuzz testing to identify unexpected behaviors or crashes

2. Secure Infrastructure

2.1 Access Control

• Development and production environments are separated.
• Access to source code repositories and servers is restricted to authorized personnel and secured using strong authentication mechanisms.
• Least privilege principles are applied to minimize access to sensitive data and systems.

2.2 Backup and Recovery

• Regular backups of critical data and source code are performed.
• Backups are encrypted and stored in multiple secure locations.
• Disaster recovery plans are in place and tested periodically.

2.3 Secure Communication

• Communication between servers, as well as between our application and external services, is encrypted using industry-standard protocols.
• Sensitive data is never transmitted or stored in plaintext.

3. Application Security

3.1 End-User Security

• The software is digitally signed to ensure authenticity and integrity.
• Updates are delivered securely via a trusted update mechanism to prevent tampering.
• Optional password protection for PDF files edited with our software.

3.2 Data Privacy

• PDF Annotator does not collect or transmit user documents or personal information without explicit user consent.
• Any temporary files created during operation are securely deleted upon application exit.

4. Employee Awareness and Training

• Security awareness training is provided to all employees.
• Employees are educated on secure coding practices, phishing prevention, and how to handle sensitive information.

5. Incident Response Plan

• We maintain an incident response plan to address potential security breaches or vulnerabilities.
• Security incidents are logged, reviewed, and remediated promptly.
• Customers are notified in the event of a significant security issue impacting their data or the software.

Conclusion

The security of PDF Annotator and the data handled by our software is of utmost importance to us. By adhering to industry best practices, continuously improving our processes, and staying informed about emerging threats, we aim to provide a secure and reliable product for our users. We remain committed to maintaining the trust our customers place in us.
