Understanding IPSec Transport and Tunnel Modes: Securing Network Traffic

Image
IPSec (Internet Protocol Security) is a framework of open standards for ensuring private, secure communications over IP networks through cryptographic security services. IPSec operates in two distinct modes: Transport Mode and Tunnel Mode, each suitable for different security scenarios. Analyzing how each mode functions helps in determining the appropriate application to secure network traffic effectively.  IPSec Transport Mode  Functionality and Usage In Transport Mode, IPSec encrypts only the payload and ESP trailer of an IP packet, leaving the header untouched. This mode is typically used for end-to-end communications between devices, such as between a client and a server or between two servers in a private network. The main advantage of Transport Mode is that it provides a secure connection without altering the IP headers, allowing the packets to move seamlessly across the network without requiring adjustments by routers.  Operational Process Authentication and Key Exchange : Befor

Web Application Firewalls

Image
  Introduction A WAF helps protect web applications by filtering and monitoring HTTP traffic between a web application and the Internet. This article delves into the workings of WAF technology, provides concrete examples and use cases, and offers insights into how organizations can leverage this technology for enhanced security. How a Web Application Firewall Works A Web Application Firewall functions by sitting between the web application and the client, acting as a shield that inspects incoming and outgoing traffic. Here’s a breakdown of how WAF technology works. Traffic Monitoring The WAF continuously monitors HTTP/HTTPS traffic to and from the web application. It inspects requests and responses for suspicious patterns, anomalies, and known attack signatures. Rule-Based Filtering WAFs operate on a set of predefined rules that detect and block malicious traffic. These rules can be customized based on the specific needs and vulnerabilities of the web application. Commonly used rule se
