Web Security Using Certificates, CDNs, and Firewalls

In today’s interconnected digital landscape, web security is paramount. To maintain the integrity and confidentiality of data, it is crucial to use a combination of tools and technologies. This chapter focuses on three key components – certificates, Content Delivery Networks (CDNs), and firewalls. We will also see how we can use certificates alongside load balancers. Certificates, particularly X.509, play a vital role in securing communications between clients and servers by enabling TLS (short for Transport Layer Security). This encryption helps to safeguard data in transit, making it essential for preventing data breaches and maintaining privacy.

Load balancers enhance the reliability and performance of web services by efficiently distributing incoming network traffic across multiple servers. By doing so, they ensure that no single server bears too much load, thus preventing downtime and optimizing resource use...
