Google CS Network Protocols

Network Protocols A set of rules for devices to communicate over a network, describing data delivery and structure. Serve as instructions for receiving devices to process data. Categories of Network Protocols Communication Protocols: govern data exchange and transmission between devices. Management Protocols: monitor and manage network activity. Security Protocols: ensure secure data transmission using encryption. Communication Protocols TCP (Transmission Control Protocol): establishes connections and streams data between devices. UDP (User Datagram Protocol): connectionless protocol for fast data transmission.

Understanding OCSP: Enhancing Digital Certificate Security

Understanding OCSP: Enhancing Digital Certificate Security The Online Certificate Status Protocol (OCSP) is a critical mechanism for maintaining the security of servers and network resources by checking the status of digital certificates in real-time. OCSP is an alternative to the older Certificate Revocation List (CRL) method, which required frequent updates to ensure client-side accuracy. How OCSP Works OCSP addresses the main limitation of CRLs by providing real-time certificate status checks. When a user attempts to access a server, OCSP sends a request for the certificate status.

Understanding Certificate Revocation Lists (CRLs)

What is a Certificate Revocation List (CRL)? A Certificate Revocation List (CRL) is a critical security feature that maintains the trustworthiness of digital communications. Managed by a Certificate Authority (CA), a CRL is a directory of digital certificates that have been invalidated before their scheduled expiration dates. This list helps various endpoints, such as web browsers, determine whether a certificate should be trusted. CRLs are essentially blocklists of certificates that should no longer be trusted.

Intro to Networks

Hub Switch Router & Modem Hub: A basic networking device that connects multiple Ethernet devices, making them act as a single network segment. It broadcasts data to all connected devices, which can lead to collisions and inefficiencies. Switch: An advanced version of a hub that connects devices on a local area network (LAN). Unlike a hub, a switch intelligently forwards data only to the specific device that needs it, reducing collisions and improving network efficiency.
