DDoS Protection: Distributed Denial of Service (DDoS) attacks can overwhelm a website or application with a flood of traffic, rendering it inaccessible to legitimate users.
CDNs often include DDoS protection mechanisms to mitigate these attacks by filtering malicious traffic and allowing only legitimate requests to reach the origin server.
Web Application Firewall (WAF): A WAF is a security system that monitors and filters HTTP traffic between a web application and the internet. CDNs may offer WAF capabilities to inspect incoming traffic for suspicious or malicious activity, such as SQL injection attacks, cross-site scripting (XSS), and other common web application vulnerabilities. WAFs can help protect against unauthorized access and data breaches.
SSL/TLS Encryption: Secure Socket Layer (SSL) and Transport Layer Security (TLS) encryption protocols are used to encrypt data transmitted between a web server and a user’s browser, ensuring that sensitive information remains private and secure. Many CDNs offer SSL/TLS encryption as part of their services, allowing websites to enable HTTPS encryption easily.
Bot Management: CDNs may include bot management capabilities to distinguish between legitimate user traffic and automated bot traffic. Bot management features can help prevent malicious bots from scraping content, committing fraud, or launching attacks against the website or application.
Content Security Policies (CSP): CSP is a security standard that helps prevent various types of attacks, including cross-site scripting (XSS) and data injection attacks, by specifying which content sources are allowed to be loaded on a web page. Some CDNs offer CSP enforcement capabilities to help enforce these policies and protect against common web security vulnerabilities.
IP Reputation Blocking: CDNs may maintain lists of known malicious IP addresses and automatically block traffic from these sources. This helps prevent attacks from known bad actors and reduces the risk of security incidents.
Access Control: CDNs may offer access control features to restrict access to certain content or resources based on predefined rules. This can help enforce security policies and prevent unauthorized access to sensitive information.
By leveraging these security features, websites and applications can enhance their security posture and reduce the risk of security breaches, downtime, and data loss. CDNs play a crucial role in protecting online assets and ensuring a safe and secure browsing experience for users.
