Quick recap
Debajit discussed the importance of security in complex architectures, particularly against malicious traffic and application-level threats, and introduced the concept of a Web Application Firewall (WAF) for web application security. He also explained the integration of web solutions with AWS, the use of WAF for blocking requests from specific countries, and the importance of implementing rules in AWS to protect against malicious attacks. Lastly, he discussed the AWS Health Dashboard, the functionalities of AWS services, the importance of tagging in AWS services, and the use of the AWS Tag Editor for better visibility and control.
Summary
Web Application Firewall and Security
Debajit discussed the ongoing recording sessions and the importance of understanding the various services and their uses. He emphasized the need for security in complex architectures, particularly against malicious traffic and application-level threats. Debajit highlighted the role of a Web Application Firewall (WAF) in protecting against cross-site scripting and SQL injections. He explained that WAF sits at layer 7 of the OSI model and is specifically designed for web application security. Debajit also mentioned that he would discuss other types of firewalls in future sessions.
Web Solutions Integration With AWS
Debajit discussed the integration of web solutions with AWS, focusing on the architecture and positioning of the web. He explained that the web can be integrated with the applications load balancer and the CloudFront CDN. Debajit also discussed the creation of a web access control list (WAF) and its integration with the CloudFront. He demonstrated how to view the WAF dashboard, which provides insights into blocked requests and their sources. Debajit concluded by mentioning the possibility of creating a new WAF.
WAF Rules and AWS Security Integration
Debajit discussed the use of Web Application Firewall (WAF) for blocking requests from specific countries, as per customer requirements. He explained the process of creating a rule to block requests from all countries except Bahrain, and demonstrated how to delete or edit these rules. Debajit also mentioned the importance of AWS security and suggested subscribing to the AWS security specialty course. He further discussed the integration of WAF with various services such as Amazon API Gateway, App Runner, and AppSync. Debajit also hinted at launching a new course on AWS database specialty.
Implementing AWS Rules for Security
Debajit discussed the importance of implementing rules in AWS to protect against malicious attacks. He explained the process of creating and managing rules, including the use of AWS Manage Rules and third-party rules from companies like F5, Fortinet, and Imperva. Debajit also highlighted the importance of testing and enabling rules before blocking requests to avoid catastrophic situations. He further explained the concept of rate-based rules and how they can be used to limit request rates. Debajit also touched on the topic of IP settings and the creation of custom IP sets for specific environments. He concluded by mentioning the integration of JavaScript SDKs and the bot control feature, which requires a separate payment.
Protecting Against DDoS Attacks With Shield
Debajit discussed the importance of protecting against Distributed Denial of Service (DDoS) attacks, which involve overwhelming a network with requests from various locations. He explained that while Network Access Control List (NaCl) can protect against a limited number of attacks, it becomes difficult to manage when the number of requests exceeds thousands. Debajit introduced Shield, a service that can be tightly integrated with NaCl to protect against DDoS attacks. He noted that Shield is an expensive service, costing $3,000 per month, but is necessary for enterprise customers who want advanced protection against security threats. Debajit also mentioned that Shield provides a summary of attacks and their locations, helping to identify potential threats.
