How do Passkeys Work? "When you create an account using passkeys, your device creates a public-private key pair. The public key is stored on the service's servers while the private key is securely stored on your device, within dedicated components designed to keep sensitive data. These include Secure Enclave on Apple devices, Trusted Platform Module (TPM) on Windows and Android, and Samsung Knox for Galaxy devices. These components are isolated from the main processor, and function as a vault, which even in the event of malware attack or breach, sensitive user data remains secure. Passkeys also work across devices; thanks to secure ecosystems, private keys are synchronized across all devices, making authentication seamless on any device where a cloud account such as iCloud or Google is active. Upon login, Instead of asking the user for a password, the service is asking the user to use the device unlock mechanism. The device signs the challenge with the private key and sends it back to the service for verification by the public key. The private key is scoped per domain. The device creates a time-based signature for each login attempt and expires shortly after it is created, ensuring that even if intercepted, it cannot be reused or exploited. This happens in real time and provides a very secure and seamless login." https://lnkd.in/g5BMurj5

Are you tired of managing 100s of passwords? I have something that can remove the need for all those passwords. FIDO (Fast Identity Online) authentication stands out as an alternative to traditional password-based systems, offering enhanced security and convenience. So what is FIDO? It is a set of open standards developed by the FIDO Alliance to create more secure and user-friendly authentication mechanisms. It uses public-key cryptography, eliminating the need for passwords. Technical Breakdown: Registration Process: When you sign up with a FIDO-enabled service, your device creates a new public/private key pair. The private key stays securely on your device, while the public key is registered with the service. Authentication Process: When you log in, the service sends a challenge to your device. Your device signs this challenge with the private key, sending the signed response back. The service verifies the response using the public key. Types of FIDO Authentication: FIDO U2F (Universal 2nd Factor): Adds an extra layer to existing passwords, often using a USB token. FIDO UAF (Universal Authentication Framework): Enables passwordless authentication using biometrics or PINs. FIDO2/WebAuthn: Extends FIDO's capabilities to web applications, enabling seamless, passwordless authentication across platforms. Why FIDO? Security: It protects against phishing, man-in-the-middle, and replay attacks. User Experience: Streamlines logins, making them faster and more intuitive. Privacy: Keeps biometric data and private keys on your device, ensuring personal information stays secure. With major organizations like Google, Microsoft, and Facebook adopting FIDO standards, it’s clear this method is reshaping online security. How do you see FIDO authentication changing the future of online security? #Authentication #FIDO #Security

Ever wondered how you seamlessly log in to different apps using the same credentials? That's the magic of identity protocols! Let's dive into some common identity protocols that you might encounter in your digital journey: 1️⃣ OpenID Connect (OIDC): Imagine this as a secure way to verify your identity across different applications. It works by building on top of OAuth2, another protocol that handles authorization (think permissions). OIDC uses JSON tokens, a lightweight and modern format, to exchange information between applications. 2️⃣ Security Assertion Markup Language (SAML): SAML is an open standard for exchanging authentication and authorization data between different parties. It's based on XML and is used to communicate security information, like who you are and what you're allowed to access, between an identity provider and a service provider. These protocols are like behind-the-scenes heroes, ensuring a smooth and secure login experience for users. #identityaccessmanagement #IAM #microsoft #microsoftsecurity #microsoftsc300 #cybersecurity #comptia #security+ #cysa+ #cc

𝗗𝗮𝘆 𝟮𝟬 𝗼𝗳 𝗠𝘆 𝟯𝟬-𝗗𝗮𝘆 𝗜𝗔𝗠 𝗖𝗵𝗮𝗹𝗹𝗲𝗻𝗴𝗲: 𝗦𝗶𝗺𝗽𝗹𝗶𝗳𝘆𝗶𝗻𝗴 𝗢𝗔𝘂𝘁𝗵 🎄 Today, I want to discuss OAuth 2.0 (Open Authorization), a standard that allows applications to access resources on behalf of users. 𝙆𝙚𝙮 𝙋𝙤𝙞𝙣𝙩 - OAuth 2.0 is focused on authorization, not authentication. It differs from protocols like OpenID Connect (OIDC). One of its primary uses is enabling third-party login integration. This allows users to log into applications using their credentials from providers like Google, Facebook, or Twitter, simplifying the login process and enhancing user experience. OAuth 2.0 uses Access Tokens to grant authorization for resource access. The widely used JSON Web Token (JWT) format may include expiration dates for security. 𝗥𝗼𝗹𝗲𝘀 𝗶𝗻 𝗢𝗔𝘂𝘁𝗵 𝟮.𝟬: • Resource Owner: The user or system that owns the protected resources. • Client: The application needing access to those resources, requiring the appropriate access token. • Authorization Server: Issues access tokens after authenticating and obtaining consent from the resource owner. • Resource Server: Protects user resources and validates access tokens before granting access. #IAM #OAuth #Cybersecurity #AccessControl #DigitalSecurity #30DayChallenge

Day 10 of David Meece #cybertechdave100daysofcyberchallenge Encryption in Transit vs. End-to-End Encryption: Understanding the Difference In a world where data security is paramount, understanding encryption methods is key to protecting sensitive information. Two commonly misunderstood terms are Encryption in Transit and End-to-End Encryption (E2EE). Let’s break it down! A)Encryption in Transit- Encryption in transit protects data while it is being transmitted across networks—like moving through your browser, email servers, or APIs. Think HTTPS, VPNs, or TLS for web traffic. Example: When you shop online, HTTPS encrypts your payment details as they travel from your device to the retailer’s server. Important: Once the data arrives at its destination (e.g., servers on the other side), it’s decrypted. Here, the server or intermediary systems can access and process your data. B)End-to-End Encryption (E2EE)- E2EE takes encryption a step further. With E2EE, your data is encrypted on your device and can only be decrypted by the intended recipient, no one in between (not even the service provider) can access it. Example: Secure messaging apps like WhatsApp provide E2EE to ensure that only you and the person you are messaging can read the conversation—even the app provider cannot. Important: While E2EE is highly secure, it might not apply to metadata (e.g., when or where the message was sent). So, what is the difference? Encryption in Transit offers protection while data is being transmitted. Once it reaches its destination, the server or application can access the data. End-to-End Encryption ensures only intended recipients can access the data. Even service providers or administrators can not decrypt it. Why Does This Matter? Encryption in transit is critical for securing web traffic, file uploads, and other communications. However, E2EE adds an extra layer of privacy, ensuring only you and your recipient can access sensitive information. As businesses, choosing the right encryption method depends on the sensitivity of your data and your privacy needs. Remember: encryption is not a one size fits all solution, layered security is the key! #DataSecurity #Encryption #Cybersecurity #EndToEndEncryption

Demystifying Public & Private Keys in Website Authentication & Encryption Public and private keys are the backbone of secure communication and website authentication. Here’s a simple breakdown: 🔑 Public Key: • Shared openly and used to encrypt sensitive data (like passwords or payment details). • Example: When you visit a secure website (HTTPS), your browser uses the website’s public key to safely send your data. 🔒 Private Key: • Kept secret by the website’s server. • Example: The server decrypts your data using its private key, ensuring only the intended recipient can access it. 💡 In Testing: • Authentication Testing: Validates secure login processes using public-private key pairs. • Encryption Testing: Ensures sensitive data is correctly encrypted and only accessible by the intended party. Why does this matter? To protect against eavesdropping, prevent data breaches, and maintain trust in online transactions. Secure communication isn’t just a necessity—it’s the foundation of modern web interactions. Are your systems up to the challenge? #cybersecurity #websecurity #webtesting
