A Denial of Service (DoS) attack aims to disrupt the normal functioning of a service by overwhelming it with excessive traffic, rendering it unavailable to legitimate users. Mitigation strategies include:

Rate Limiting: Implement limits on the number of requests from a single source to prevent abuse.
Traffic Filtering: Use firewalls and intrusion detection systems to filter out malicious traffic.
Load Balancing: Distribute traffic across multiple servers to manage load and prevent single points of failure.
Anti-DDoS Services: Employ specialized services that detect and mitigate distributed denial of service (DDoS) attacks.

DevSecOps integrates security practices into the DevOps process, aiming to make security an integral part of the software development lifecycle. It emphasizes the importance of embedding security measures early in the development process rather than addressing them at the end. This approach involves automating security checks, conducting regular vulnerability assessments, and fostering collaboration between development, security, and operations teams. DevSecOps is important because it helps identify and mitigate security vulnerabilities early, reducing the risk of breaches and ensuring compliance with regulatory standards.

A Content Delivery Network (CDN) is a network of geographically distributed servers that work together to deliver web content, such as images, videos, and scripts, to users more efficiently. The primary purpose of a CDN is to reduce latency and improve load times by caching content closer to the end user. This not only enhances the user experience but also reduces the load on the origin server and can help with handling high traffic volumes and mitigating DDoS (Distributed Denial of Service) attacks.

HTTP (HyperText Transfer Protocol) and HTTPS (HyperText Transfer Protocol Secure) are protocols used for transmitting data over the web. The key difference is that HTTPS includes an additional layer of security through SSL/TLS encryption. This means that data transmitted over HTTPS is encrypted, making it more secure against eavesdropping and tampering. HTTPS is crucial for protecting sensitive information, such as login credentials and payment details, from being intercepted by malicious actors.

APIs (Application Programming Interfaces) are sets of rules and protocols that allow different software applications to communicate with each other. They define the methods and data formats that applications can use to request and exchange information. APIs play a crucial role in software development by enabling integration between disparate systems, facilitating the use of third-party services, and allowing developers to build applications that leverage existing functionalities without needing to reinvent them.
