AOSSL - Always on SSL
AOSSL (Always on SSL) refers to a security practice in which all pages and all content on a website are served exclusively over a secure HTTPS (SSL/TLS) connection, rather than using unsecured HTTP for any part of the site. The aim is to enhance data privacy and integrity for users by ensuring encrypted communication at all times, not just on login pages or checkout flows.
Key Features and Benefits
Full-Site Encryption
Under AOSSL, every resource (HTML, images, scripts, etc.) is delivered via HTTPS, preventing data from being intercepted or tampered with in transit.
Protection of Sensitive Information
User credentials, payment details, and any other sensitive data remain secure throughout the entire browsing session.
This approach helps reduce risks like session hijacking or man-in-the-middle attacks.
Consistent User Experience
Instead of switching between HTTP and HTTPS, users see the secure padlock icon in their browser at all times, promoting trust in the website.
SEO Advantages
Major search engines, such as Google, give a slight ranking boost to HTTPS-enabled sites.
Secure sites often load more reliably across networks, resulting in better user engagement metrics (like lower bounce rates).
Compliance with Industry and Regulatory Standards
Certain data protection regulations may require an encrypted channel for handling personal or financial information. AOSSL ensures compliance by default.
Implementation Considerations
Server Configuration
Obtain and correctly install an SSL/TLS certificate (e.g., from a Certificate Authority or using services like Let’s Encrypt).
Update server settings so that all HTTP requests are redirected to HTTPS (301 redirect).
Mixed Content Prevention
Ensure that all internal links, images, scripts, and embedded content use secure URLs (
https://
).
Any non-HTTPS resource loaded within an HTTPS page can trigger browser warnings or block content entirely.
Performance Optimization
Modern HTTPS protocols typically offer efficient encryption, meaning minimal performance overhead.
Techniques such as HTTP/2 further optimize loading speed under HTTPS by enabling multiplexing and other enhancements.
Testing and Maintenance
Check for SSL configuration errors and test different browser/client environments to confirm everything is served securely.
Keep certificates and server software up to date to guard against emerging security threats.
Conclusion
AOSSL (Always on SSL) is the practice of enforcing HTTPS for every page and resource on a website. By consistently encrypting data in transit, AOSSL helps maintain user privacy, protect sensitive transactions, and build trust, while also offering advantages in search rankings and regulatory compliance.
