Modern antivirus software provide protection not only from virus, but also from worms, Trojan-horses, adwares, spywares, keyloggers, etc. It was originally designed to detect and remove viruses from computers. AntivirusĪn antivirus is a tool that is used to detect and remove malicious software. A software firewall protects your computer from internet threats.

Software firewalls are installed on your computers. For larger networks − e.g., for business purpose − business networking firewall solutions are available. Most hardware firewalls provide a minimum of four network ports to connect other computers. These are also found in broadband routers. Hardware firewalls are standalone products. A firewall also helps in providing remote access to a private network through secure authentication certificates and logins. Every message entering or leaving the intranet goes through the firewall to be examined for security measures.Īn ideal firewall configuration consists of both hardware and software based devices. Many routers that pass data between networks contain firewall components and conversely, many firewalls can perform basic routing functions.įirewalls are commonly used in private networks or intranets to prevent unauthorized access from the internet. Most personal computers use software-based firewalls to secure data from threats from the internet. Firewalls that are hardware-based also provide other functions like acting as a DHCP server for that network. A firewall establishes a barrier between a trusted internal network and the internet.įirewalls exist both as software that run on a hardware and as hardware appliances. FirewallsĪ firewall is a network security system that manages and regulates the network traffic based on some protocols. Examples include firewalls, content filtering, web caching, etc. These devices serve as all-in-one security devices. For example, penetration testing devices and vulnerability assessment appliances. These devices scan the networks and identify potential security problems. These devices identify and report on unwanted traffic, for example, intrusion detection appliances. Firewalls, antivirus scanning devices, and content filtering devices are the examples of such devices. These security devices block the surplus traffic. Types of Network Security Devices Active Devices The most common and simple way of protecting a network resource is by assigning it a unique name and a corresponding password. It is the duty of network administrators to adopt preventive measures to protect their networks from potential security threats.Ĭomputer networks that are involved in regular transactions and communication within the government, individuals, or business require security. Network security is the security provided to a network from unauthorized access and risks.
