A web proxy is used primarily to enhance privacy, security, and access control when browsing the internet. It acts as an intermediary between a user’s device and the websites they visit, intercepting and forwarding web requests. Web proxies can mask the user’s IP address, making their online activities more anonymous. They also cache web content, … Read more
A peer-to-peer (P2P) network is a decentralized communication model where participants, called peers, share resources directly with each other without the need for a centralized server. In a P2P network, each peer acts both as a client and a server, capable of initiating connections to other peers to share files, services, or other resources. This … Read more
The four types of cloud storage are: Public Cloud Storage: Managed by cloud service providers and accessible over the internet to the general public or multiple organizations. Examples include Amazon S3, Google Cloud Storage. Private Cloud Storage: Operated solely for a single organization, either managed internally or by a third-party vendor. It offers more control … Read more
Cloud storage refers to storing data on remote servers accessed through the internet rather than on local storage devices. It allows users to upload, store, and manage data securely while enabling convenient access from anywhere with an internet connection. Cloud storage providers manage the infrastructure and ensure data availability, scalability, and redundancy. To use cloud … Read more
Cloud architecture refers to the design and structure of cloud computing environments, encompassing various components and technologies that enable the delivery of cloud services. It typically involves multiple layers and components, each serving specific functions to ensure scalability, flexibility, and reliability of cloud-based applications and services. Key components include virtualization, networking, storage, management tools, and … Read more
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
There are several methods of load balancing that distribute incoming network traffic across multiple servers or resources to optimize performance and ensure high availability: Round Robin: In this method, requests are sequentially distributed across a group of servers in a circular order. Each server is assigned a turn to handle incoming requests, ensuring an even … Read more
