Secure Password Management System with Geolocation Analysis
Secure Password Management System with Geolocation Analysis
In the modern digital landscape, security is paramount, especially concerning user authentication processes. The development of a secure, modular, and user-friendly application that adheres to established
security standards is essential for safeguarding sensitive information. This paper discusses the design and implementation of a Python-based web application hosted on AWS Cloud9, focusing on creating robust login and password management features aligned with NIST SP 800-63B guidelines, enhanced with logging, monitoring, and geolocation functionalities.
Introduction
The primary goal of this project is to develop a web application facilitating user authentication, password updates, and security monitoring. It employs Python and Flask frameworks within the Cloud9 IDE environment, leveraging file-based data storage and external libraries for security features, logging, and geolocation. The system emphasizes security best practices, including password complexity enforcement, common password detection, rate-limiting, and log auditing.
Design and Functional Components
Password Login and User Authentication
The login form enables users to enter their username and password, which are validated against stored credentials in a file. To ensure secure authentication, the application utilizes secure sessions and password hashing mechanisms. Upon successful login, the user receives a greeting message. If credentials are invalid, the system logs the attempt with details like timestamp and IP address, and enforces rate limiting to prevent brute-force attacks.
Password Storage and Security Verification
User credentials are maintained in a plain text or structured file. Passwords are checked for compliance with NIST guidelines, which specify a minimum length of 8 characters, a maximum of 64, and the exclusion of commonly-used or compromised passwords, as listed in CommonPasswords.txt. The application compares the input password against this list using efficient search algorithms, such as Python list membership checks.
The application employs password validation functions that enforce these rules and provide user feedback on rejection reasons, improving usability and security. When a password fails validation, the user is prompted to select a different secret.
Password Update Functionality
Authenticated users can update their passwords via a dedicated form. The system verifies the new password with the same security criteria as during login—length, safety, and entropy. Post-validation, the system updates the credentials file securely and confirms the change to the user.
Rate Limiting and Lockout Mechanisms
To thwart brute-force attacks, the system enforces rate limiting after 15 failed attempts from a particular IP address within a defined window, such as five minutes. The attempt count and timestamps are stored temporarily, with failed attempts logged with date, time, and IP address.
Successful authentication resets these counts, ensuring legitimate users are not hindered after successful login.
Logging and Log Analysis
All failed login attempts are logged into a dedicated file, including the date, time, and IP address. This log serves as a record for audit and security analysis. A separate Python log analyzer reads this log, identifies IP addresses with more than 10 failed attempts within a five-minute window, and utilizes the ip2geotools library to geo-locate these IPs.
The geolocation results include latitude and longitude coordinates, providing insight into the origins of suspicious activities. An example report details the IP, number of failed attempts, date of activity, and geographic coordinates, useful for security incident response.
Implementation Details
Web Framework and File Handling
The system employs Flask to manage web routes and forms, handling user inputs securely. User credentials are stored in structured text files, loaded into memory at runtime, and updated as needed. Data structures like Python lists facilitate fast password searches.
Security and Validation Functions
Core functions include: validate_password_length:
Ensures password is at least 8 and no more than 64 characters.
check_common_password:
Checks if the password exists in CommonPasswords.txt.
rate_limit_attempts:
Tracks and limits failed login attempts per IP.
log_failed_attempt:
Records failures with timestamp and IP.
All functions are designed modularly to maximize code reuse and readability.
Geo-location with ip2geotools
The ip2geotools library, installed via pip, provides geolocation capabilities. Using the request object from Flask, the application extracts the remote IP address and queries the database for latitude and longitude coordinates using DbIpCity.
Security Considerations
The system implements multiple security layers, including:
Password complexity and safe password checks.
Rate limiting to prevent brute-force attacks.
Logging of suspicious activity for audit purposes.
Use of secure session management and input validation.
These measures align with contemporary security standards, reducing vulnerabilities and facilitating incident response.
Conclusion
This Python web application embodies a comprehensive approach to secure user authentication and activity monitoring within a cloud environment. Combining best practices for password security, activity logging, and geolocation analysis provides a strong foundation for safeguarding user data and detecting malicious activities. By leveraging Flask, file I/O, structured data management, and external geolocation libraries, this system demonstrates an effective integration of security measures and user management
capabilities crucial for modern web applications.
