Script and Browser Integrity Check

In Lucid, script and browser integrity checks are essential components of our security framework. These checks help prevent malicious scripts and browser extensions from compromising our platform's security and stealing sensitive user data.

What is Script and Browser Integrity Check?

Script and browser integrity checks refer to the mechanisms used to verify the authenticity and integrity of scripts and browser extensions interacting with our platform. This includes checking for malicious scripts, verifying browser extensions, and ensuring that all interactions are legitimate and secure.

Key Features of Script and Browser Integrity Check

1. Script Validation: We validate all scripts interacting with our platform to prevent malicious code from being executed and to ensure that only authorized scripts are allowed to run.
2. Content Security Policy (CSP): We implement a robust Content Security Policy (CSP) to define which sources of content are allowed to be executed within our platform, preventing malicious scripts from being loaded.
3. Subresource Integrity (SRI): Our platform uses Subresource Integrity (SRI) to ensure that all scripts and stylesheets loaded from external sources are authentic and have not been tampered with.

Servive Workers

In Lucid, service workers enhance the security and performance of our web applications. A service worker is a script that runs in the background, allowing us to manage network requests, cache resources, and provide a better user experience.

What are Service Workers?

Service workers are JavaScript files that run in the background, separate from the main thread of the web application. They act as a proxy between the web application and the network, allowing us to intercept and manage network requests.

Key Features of Service Workers

1. Network Request Management: Service workers enable us to manage network requests, allowing us to cache resources, handle offline requests, and provide a better user experience.
2. Resource Caching: Our service workers cache frequently-used resources, such as images, scripts, and stylesheets, to reduce the number of network requests and improve page load times.
3. Push Notifications: We use service workers to handle push notifications, allowing us to send targeted and personalized notifications to our users.
4. Background Sync: Our service workers enable background sync, allowing us to synchronize data in the background, even when the user is offline.
5. Security: Service workers provide an additional layer of security, allowing us to validate and sanitize network requests, and prevent malicious activities, such as cross-site scripting (XSS) attacks.

How We Use Service Workers

We use service workers to enhance the security and performance of our web applications, providing a better user experience and protecting our users' sensitive data. By leveraging the capabilities of service workers, we can:

1. Improve page load times and reduce latency
2. Enhance security and prevent malicious activities
3. Provide a better user experience, even in low-network conditions
4. Synchronize data in the background, ensuring that our users' data is always up-to-date

Webpage Handling

In Lucid, when a webpage opens, our platform initiates a series of security checks and protocols to ensure a safe and secure browsing experience for our users. These checks help prevent malicious activities, such as cross-site scripting (XSS) attacks, and protect our users' sensitive data.

What Happens When a Webpage Opens?

When a webpage opens, our platform performs the following security checks and protocols:

1. Domain Validation: We validate the domain of the webpage to ensure it is legitimate and authorized, preventing phishing and other types of attacks.
2. HTTPS Encryption: Our platform checks for HTTPS encryption to ensure that all data transmitted between the user's browser and our server is encrypted and secure.
3. Content Security Policy (CSP): We enforce a Content Security Policy (CSP) to define which sources of content are allowed to be executed within the webpage, preventing malicious scripts from being loaded.
4. Cross-Site Scripting (XSS) Protection: Our platform includes XSS protection mechanisms to prevent malicious scripts from being injected into the webpage and stealing sensitive user data.
5. Malware Scanning: We scan the webpage for malware and other types of malicious code, ensuring that our users are protected from potential security threats.

Content Tracing

In Lucid, content tracing is a critical security feature that helps us monitor and track the flow of sensitive data within our platform. This feature enables us to detect and prevent potential data breaches, ensuring the confidentiality, integrity, and availability of our users' sensitive information.

What is Content Tracing?

Content tracing refers to the process of monitoring and tracking the flow of sensitive data, such as Personal Identifiable Information (PII), financial data, or confidential business information, as it moves through our platform. This includes tracking data access, modifications, and transmissions to ensure that all interactions are legitimate and authorized.

Key Features of Content Tracing

1. Data Flow Monitoring: We monitor the flow of sensitive data in real-time, tracking all access, modifications, and transmissions to ensure that data is handled correctly and securely.
2. Access Control: Our platform enforces strict access controls, ensuring that only authorized users and systems can access, modify, or transmit sensitive data.
3. Audit Logging: We maintain detailed audit logs of all data interactions, providing a complete record of all access, modifications, and transmissions for forensic analysis and compliance purposes.
4. Anomaly Detection: Our platform uses advanced anomaly detection techniques to identify and alert on potential security threats, such as unauthorized data access or suspicious data transmissions.

Sessions

Lucid ensures a seamless and efficient browsing experience by managing sessions dynamically. Every time a user opens Lucid, a new session starts, ensuring that no background processes linger when the browser is closed. This means that once a session is terminated, all associated activities cease, preventing unnecessary resource consumption.

Lucid's session handling is tightly integrated with Context Bridge, allowing secure and efficient communication between different browser components while maintaining user privacy and security.

Why Session Management Matters

Proper session management brings several benefits to the user, such as:

1. Resource Efficiency: Since Lucid does not leave background processes running, it conserves system resources.
2. Security and Privacy: Closing the browser ensures all processes are terminated, reducing potential attack vectors.
3. Better Performance: Sessions are designed to start fresh each time, reducing unnecessary clutter and optimizing the browsing experience.

Debugger

We value transparency and security, which is why it includes a built-in debugger that logs all processes performed on a user's computer. These logs are stored locally, ensuring complete control over the data. This system enhances security, privacy, and usability by providing insights into browser activity.

Why Debugging is Important

1. Transparency: Users can verify what processes the browser runs in the background.
2. Security: Log files help identify any unauthorized actions or vulnerabilities.
3. Bug Tracking: If a bug occurs, Team Aquin can use the logs to diagnose and resolve issues efficiently.

By keeping logs on the user's device rather than sending them externally, Lucid maintains a strong stance on privacy while offering a useful tool for troubleshooting and security.

Cross Origin Resource Sharing and Same Origin Policy

Our primary goal is to provide a safe and seamless browsing experience for our users. Two crucial security features that help us to achieve our goal are Cross Origin Resource Sharing (CORS) and Same Origin Policy (SOP).

What is SOP?

SOP is a fundamental security feature that states that a web page can only access resources, such as stylesheets, images, and scripts from the same origin:

• The same protocol (HTTP or HTTPS)
• The same domain (aquin.app)
• The same port (80 or 443)

What is CORS?

CORS is a mechanism that allows web pages to access resources from different origins, while still maintaining the security features of SOP. CORS enables web servers to specify which origins are allowed to access their resources, and under what conditions.

How have we improved security?

We have made significant improvements to CORS and SOP implementations to provide an even more secure browser experience. Key improvements include:

1. Strict CORS enforcement: We have made CORS enforcement stricter to prevent malicious scripts from bypassing security restrictions.
2. Improved request handling: We have optimized our request handling to reduce latency, improve performance, and enhance security.
3. Enhanced SOP restrictions: We have made SOP restrictions better to prevent malicious scripts from accessing sensitive data such as financial information, passwords, emails, and more on any website.

Content Security Policy and Cross-Site Scripting

We understand the importance of protecting our users from malware. In this case, we also protect users from Cross-Site Scripting (XSS) to make our users more secure while navigating the Internet.

What is Content Security Policy and Cross-Site Scripting?

Content Security Policy (CSP) is a security feature that helps prevent Cross-Site Scripting (XSS) attacks by defining which sources of content are allowed to be executed within a web page.

Cross-Site Scripting (XSS) is a type of attack where an attacker injects malicious code into a website to steal sensitive information such as passwords, emails, authentication codes, or even take control over the user's session.

How do we prevent Cross-Site Scripting?

We prevent Cross-Site Scripting (XSS) by adding Content Security Policy (CSP) and other techniques such as:

1. Disabling Dangerous JavaScript Code Execution: We disable dangerous JavaScript Code Execution so the attacker does not attempt to do a Cross-Site Scripting attack using JavaScript.
2. Content Security Policy (CSP): Lucid has a feature called Content Security Policy that prevents Cross-Site Scripting from happening in the browser.
3. Other security methods: We have added many security methods to Lucid such as Popup Blocker

Event and Form security

We protect our users from malicious attacks. Two important areas of security are event and form security. These areas are crucial in ensuring that our users' data and information are safe from unauthorized access and malicious activities. We take the security of our users very seriously, and we have implemented various measures to prevent attacks and protect our users.

What are Events?

Events are a crucial part of web development, allowing users to respond to interactions such as clicks and submits. However, events can also include vulnerabilities if not secured well, such as Cross-Site Scripting (XSS) issues and event handler injection. These vulnerabilities can be exploited by attackers to steal user data or perform other malicious activities.

What is Form Security?

Forms are a common way for users to interact with a website, providing a way to collect user input. However, forms can also be a vulnerability if not properly secured, with types of security issues including form tampering and Cross-Site Request Forgery (CSRF).

How are we protecting our users?

We protect our users by using various methods of security and implementing the latest security measures possible, such as:

1. Enhanced Event Handler Validation: Lucid has improved event handler validation to detect and prevent malicious code from being injected into event handlers. This validation ensures that only authorized code is executed, preventing attackers from injecting malicious code.
2. Better Form Data Validation: We have enhanced form data validation that detects and prevents code from being submitted through forms. This validation ensures that user input is sanitized and validated, preventing attackers from injecting malicious code or stealing user data.
3. Regular Security Updates: We are committed to regularly updating our browser for security. We understand that new vulnerabilities and threats emerge every day, and we are committed to staying ahead of these threats by regularly updating our browser with the latest security patches and protections.

Secure HTTPS and HTTP

We prioritize Hypertext Transfer Protocol Secure (HTTPS) over Hypertext Transfer Protocol (HTTP) due to security reasons.

What is HTTP and HTTPS?

Hypertext Transfer Protocol (HTTP) is a protocol used to transfer data from one computer to another, such as websites. The issue with HTTP is that it is not secure, which is why we prioritize Hypertext Transfer Protocol Secure (HTTPS) for a secure connection between computers, or in this case, websites.

Risks Associated with Unsecure Connections

There can be various risks associated with unsecure connections when navigating the web. These risks primarily occur when using HTTP instead of HTTPS. These are the following risks with HTTP:

1. Man-In-The-Middle (MITM) Attacks: Unsecure connections can be vulnerable to MITM attacks, where an attacker intercepts and alters the communication between your browser and the website.
2. Data Tampering: Unsecured connections can be vulnerable to data tampering, where an attacker alters the data being exchanged between the browser and the website.
3. Data Stealing: Data stealing is the most common method that happens with an unsecure connection (HTTP). The attacker steals the data being transferred between computers (in this case with websites). The data can include passwords, usernames, financial information, or more private information.

What do we do to get a secure connection?

We use various methods to establish a secure connection, such as prioritizing HTTPS over HTTP whenever possible. We have implemented the following methods:

1. HTTPS by Default: We have implemented HTTPS by default if it is available on the visited website.
2. Encryption: Lucid has implemented encryption, which protects your data from interception, data stealing, and more.

JavaScript Code Execution

We understands the importance of ensuring the security of our user's browsing experience. One of the most important security issues is with code execution, such as JavaScript.

What is JavaScript Code Execution?

JavaScript is a programming language used to create websites and more. It allows developers to add effects and respond to user interactions, among other things. However, there is a problem: with JavaScript, you can also execute malicious scripts, which can compromise the security of the browser and put your data at risk.

Risks with JavaScript Code Execution

There are several risks with JavaScript code execution, such as:

1. Cross-Site Scripting (XSS): XSS attacks occur when an attacker injects malicious code into a website, which can be executed in the browser.
2. Malicious Script Injection: An attacker can execute malicious JavaScript code in any browser, allowing them to steal important and private data.

How do we prevent it?

We prevent it by using up-to-date libraries and code in Lucid, as well as other techniques such as Sandboxing and more.

We provide additional measures, including:

1. Content Security Policy (CSP): Implementing Content Security Policy (CSP) to define which sources of content are allowed to be executed within a web page. This helps prevent inadequate scripts from being executed.
2. JavaScript Sandbox: We use Sandboxing to ensure a protected environment in Lucid.
3. Suspicious Site Blocker: We use a Suspicious Site Blocker technique to block malicious sites.

Malware and Phishing Protection

We understand the importance of protecting our users from malware and phishing attacks. That is why we have implemented robust security measures to detect and prevent these types of threats.

What is Malware?

Malware is a program whose main purpose is to steal data from people or damage their Operating System. Malware can steal and edit all types of data such as passwords, emails, usernames, financial information, private information, and it can also edit or create files to include fake information or execute more malware.

What is Phishing?

Phishing is a type of online attack where an attacker attempts to trick a user into revealing sensitive information, such as passwords, financial information, photos, and all types of files. This method involves fake emails, websites, or messages that appear to be legitimate but are actually designed to steal your private information.

Risks with Malware and Phishing

There are various risks with these types of methods to steal information, such as:

1. Data Theft: Malware and phishing attacks can compromise your personal data, including emails, passwords, and all types of data.
2. Financial Loss: These types of stealing methods can cause financial loss, either through direct theft or by compromising your financial information.
