DNS (Domain Name System) rules refer to the guidelines and configurations that govern the operation and management of DNS within a network or organization. These rules include setting up DNS servers, configuring zones and records, defining DNS resolution behavior, and ensuring security and reliability of DNS services. DNS rules also encompass policies for DNS name … Read more
The five basic commands of SNMP (Simple Network Management Protocol) are used for managing and monitoring network devices and systems. These commands include: GET: Retrieves the value of a specified object or variable from an SNMP agent running on a network device. It is used to query the current status or configuration of a device. … Read more
The SMTP (Simple Mail Transfer Protocol) method refers to the set of rules and procedures used for sending emails between servers and from email clients to servers. SMTP defines how email messages are formatted, transmitted, and delivered over the internet. It operates on TCP port 25 (or port 587 for encrypted connections using STARTTLS). When … Read more
Denial of service (DoS) refers to a cyberattack that aims to disrupt or temporarily suspend the services of a host connected to the internet, typically by overwhelming the target system with a flood of malicious traffic. This flood of traffic can exhaust system resources such as bandwidth, processing power, or memory, rendering the system unavailable … Read more
Ethernet transmits data using a protocol called the Ethernet protocol, which is part of the IEEE 802.3 standard. It employs a method known as packet switching, where data is divided into smaller units called frames. Each frame contains the destination and source addresses, as well as error-checking information to ensure data integrity. Frames are transmitted … Read more
DDoS, or Distributed Denial of Service, is a type of cyberattack where multiple compromised systems, often infected with malware and controlled remotely by attackers, are used to flood a target system or network with overwhelming traffic. This flood of traffic can exhaust the target’s resources such as bandwidth, processing power, or memory, leading to a … Read more
Ethernet works by using a protocol called Ethernet protocol, which is part of the IEEE 802.3 standard, to facilitate communication over a local area network (LAN). It divides data into frames, which contain source and destination addresses and error-checking information. These frames are transmitted over physical media like copper or fiber optic cables, ensuring data … Read more
WPA (Wi-Fi Protected Access) protocol is a security standard designed to secure wireless computer networks. It provides encryption and authentication mechanisms to protect data transmitted over Wi-Fi networks from unauthorized access. WPA was developed as an improvement over the earlier WEP (Wired Equivalent Privacy) protocol, which had vulnerabilities that made it susceptible to attacks. Wi-Fi … Read more
TLS (Transport Layer Security) is a cryptographic protocol designed to provide secure communication over a computer network. It ensures the privacy and data integrity between two communicating applications, such as a web browser and a server. TLS encrypts the data exchanged, preventing eavesdropping and tampering. It also includes mechanisms for authenticating the communicating parties, often … Read more
HTTP (HyperText Transfer Protocol) itself is not tied to any specific programming language. It is a protocol used for transmitting hypermedia documents, such as HTML. Programming languages like Python, JavaScript, Java, Ruby, and others can implement HTTP functionality through libraries or built-in modules that handle HTTP requests and responses. These languages provide APIs and tools … Read more
