Firewalls are essential for protecting against cyber threats, acting as a barrier between trusted internal networks and untrusted external networks. They monitor and control network traffic based on predetermined security rules. Choosing the right type of firewall depends on factors like organization size, budget, and security needs. See Also There are various types of firewalls, … Read more
A computer or network firewall is the first line of defense in safeguarding computer and networking resources. At a basic level a firewall works by filtering incoming and outgoing traffic based on predefined rules. From simple packet filtering to advanced deep packet inspection, firewalls help prevent unauthorized access and minimize the risk of cyberattacks. See … Read more
Introduction Port scanning tools are software applications designed to scan and analyze the open ports on a computer system or network. These tools are used to identify which ports are active, closed, or filtered. By scanning a system’s ports, network, and security admins can determine what potential vulnerabilities exist, and which measures to take to … Read more
Geolocation is a technique of identifying the geographic or physical location of a person or device with digital information using longitude and latitude mapping. Methods used for geolocation include Global Positioning Systems (GPS), Wi-Fi positioning, Cell tower trilateration and IP address based location mapping. Find out your IP Address and Geolocation your our public IP … Read more
Nmap is a powerful command line tool network scanning tool that is used to identify open ports, services, and vulnerabilities on a network. Nmap works by sending packets to target hosts and networks and analyzing the responses or the lack thereof. The primary use for nmap is to do port scanning, which involves scanning a … Read more
In an increasingly connected world, preventing malicious activity in networked environments is critical to maintaining the security and confidentiality of sensitive information. Port scanning is a common method attackers use to identify open,closed and filtered ports on a target system, and it’s a precursor to more malicious activity, such as exploiting vulnerabilities or launching denial-of-service … Read more
What is Port Scanning and How Does it Work? Port scanning is a method that involves the examination of a network’s open and closed ports to identify vulnerabilities and access. Port scanning works by actively or passively accessing a port to find out if it is active or closed. Port scanning has therefore become a … Read more
Introduction A port is a 16-bit number used in TCP/IP (Transmission Control Protocol/Internet Protocol) networking in combination with the IP Address of a computing device to for applications and services to communicate between devices. In this post I will go over details of how and how a port is created and used. What is a … Read more
Introduction Localhost is a term used in computer networking to describe the loopback address 127.0.0.1. This IP address refers to the local computer and is commonly used not only for local testing and debugging purposes but also for running networked apps locally. A loopback address, 127.0.0.1 for localhost, is a special IP address that directs … Read more
What is a MAC Address? A MAC (Media Access Control) address is a unique identifier assigned to a hardware called network interface controller (NIC) for use as a network address. This use is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth. The NIC aka Network controller is computer hardware that makes … Read more
