Simple Mail Transfer Protocol (SMTP) works by facilitating the transfer of email messages between servers. When an email is sent, the SMTP client on the sender’s side establishes a connection to the SMTP server, typically using TCP. The client and server then communicate through a series of commands and responses to transfer the email. The … Read more
The transfer method of SFTP (Secure File Transfer Protocol) involves securely transferring files between a client and server over an encrypted connection. SFTP operates over the SSH (Secure Shell) protocol, ensuring that all data, including file contents, commands, and authentication, is encrypted during transmission. The data transfer method of SFTP relies on establishing an SSH … Read more
Intrusion detectors work by monitoring network traffic or system activities for signs of malicious activity or policy violations. These systems analyze data from various sources, such as network packets, system logs, and user behavior, to detect patterns that may indicate an intrusion. When suspicious activity is identified, the system generates alerts to notify administrators, enabling … Read more
A firewall operates as a network security system designed to monitor and control incoming and outgoing network traffic based on predetermined security rules. It acts as a barrier between a trusted internal network and untrusted external networks, such as the internet. Firewalls examine each packet of data passing through them and make decisions to allow, … Read more
The API gateway protocol refers to the standardized method or set of rules that an API gateway uses to communicate with clients and backend services. It defines how requests and responses are structured and exchanged between these components, ensuring consistency and interoperability across different systems and applications. API gateways typically use HTTP or HTTPS protocols … Read more
POP3 (Post Office Protocol version 3) is a standard protocol used for retrieving email from a remote mail server to a local email client. It is one of the most commonly used email protocols alongside IMAP (Internet Message Access Protocol). The default protocol for POP3 is TCP/IP, which is used to establish communication between the … Read more
An API gateway acts as a intermediary between clients and backend services, handling tasks such as routing requests, managing API traffic, enforcing security policies, and providing additional functionalities like authentication and rate limiting. It serves as a single point of entry for multiple APIs, simplifying client access and enhancing the scalability and security of the … Read more
The POP3 protocol operates in two modes: Download and Delete (Standard Mode): In this mode, known as standard POP3, emails are downloaded from the server to the client’s device (such as a computer or smartphone). Once downloaded, emails are typically removed from the server, which means they can only be accessed from the device that … Read more
SSL (Secure Sockets Layer) is a cryptographic protocol designed to secure communication over the internet by encrypting data transmitted between a web browser and a server. It ensures that sensitive information such as login credentials, credit card details, and personal data remains confidential and protected from unauthorized access or interception. SSL is used to establish … Read more
An API gateway is used to manage and optimize the communication between clients and backend services that expose APIs. It acts as a single entry point for multiple APIs, providing functionalities such as request routing, protocol translation, security enforcement (e.g., authentication and authorization), rate limiting, logging, monitoring, and more. Essentially, it helps streamline API management … Read more
