Mutual TLS (mTLS) is an authentication method that ensures secure communication between both parties in a connection. Unlike regular TLS, which verifies only the server’s identity, mTLS authenticates both client and server by exchanging and validating digital certificates. This approach forms a cornerstone of Zero Trust security frameworks, where nothing is trusted by default. Whether […]
Digital certificates form the backbone of secure online interactions, verifying identities and ensuring encrypted communication. However, when these certificates are compromised or misused, they must be promptly revoked to maintain trust. This is where Certificate Revocation Lists (CRLs) come in. Maintained by Certificate Authorities (CAs), CRLs are essential for identifying and invalidating revoked certificates before […]
Port 80 and port 443 define how data travels on the web. Port 80 supports HTTP, offering no encryption, while port 443 enables HTTPS, ensuring secure interactions. With online safety becoming a priority, HTTPS has replaced HTTP as the standard for secure data transmission and protection. This article explores their differences, revealing why port 443 […]
Public and private keys are vital to encryption, which keeps data secure across the internet. These cryptographic tools enable everything from safe online shopping to secure emails, but their roles and differences can be confusing. This article explains the concepts of public and private keys in simple terms, highlighting their uses, strengths, and practical applications. […]
What keeps your online banking, emails, and shopping transactions secure? Public key cryptography. This groundbreaking encryption method ensures that your data stays private and tamper-free during digital exchanges. Unlike traditional encryption methods, it uses two keys: a public key for encryption and a private key for decryption, eliminating the need for shared secrets. In this […]
The internet may seem vast and open, but behind the scenes, a network of security protocols keeps it safe. One of the key players in this system is the SSL certificate—the digital file that verifies a website’s legitimacy. But what happens when a certificate goes bad? That’s where OCSP, the Online Certificate Status Protocol, comes […]
How can you inspect encrypted data without leaving it exposed? That’s where SSL bridging makes all the difference. While many are familiar with SSL/TLS encryption, SSL bridging goes a step further by adding extra layers of protection. Whether you’re an IT professional, a student in cybersecurity, or a decision-maker exploring network security options, understanding SSL […]
When you visit a website, especially one handling sensitive information, your data must travel securely from your device to the web server. Here’s where SSL termination comes into the picture. This article explains how it works, its advantages and drawbacks, and how to implement it effectively. Keep reading, and you’ll learn how to use this […]
Have you ever wondered how you can establish secure connections without the involvement of a third party? That’s where self-signed certificates come into play. But what is a self-signed certificate, and when should it be used? In this article, we’ll dive into self-signed certs, exploring how they work, their advantages and disadvantages, and when they […]
When exploring digital security, you’ll encounter the term intermediate certificate. But what is an intermediate certificate, and why is it so significant? Let’s break it down and understand how intermediate certificates fit into the SSL/TLS framework and the broader Public Key Infrastructure (PKI).
