Network Switches

Most business networks today use switches to connect computers, printers, phones, cameras, lights, and servers in a building or campus.
A switch serves as a controller, enabling networked devices to talk to each other efficiently. Through information sharing and resource allocation, switches save businesses money and increase employee productivity.There are two basic types of switches to choose from as part of your networking basics: managed and unmanaged.
An unmanaged switch works out of the box but can't be configured. Home-networking equipment typically offers unmanaged switches.
A managed switch can be configured. You can monitor and adjust a managed switch locally or remotely, giving you greater control over network traffic and access.

Network Routers

Routers, on the other hand, connect multiple networks together. They also connect computers on those networks to the Internet. Routers enable all networked computers to share a single Internet connection, which saves money.
Routers connect your business to the world, protect information from security threats, and can even decide which computers receive priority over others. Beyond those basic networking functions, routers come with additional features to make networking easier or more secure. Depending on your security needs, for example, you can choose a router with a firewall, a virtual private network (VPN), or an Internet Protocol (IP) communications system.

Network Firewalls

Network firewalls are security devices used to stop or mitigate unauthorized access to private networks connected to the Internet, especially intranets. The only traffic allowed on the network is defined via firewall policies – any other traffic attempting to access the network is blocked. Network firewalls sit at the front line of a network, acting as a communications liaison between internal and external devices.
A network firewall can be configured so that any data entering or exiting the network has to pass through it – it accomplishes this by examining each incoming message and rejecting those that fail to meet the defined security criteria. When properly configured, a firewall allows users to access any of the resources they need while simultaneously keeping out unwanted users, hackers, viruses, worms or other malicious programs trying to access the protected network.There are a number of major firewall types that prevent harmful information from passing through the network:
Application-layer Firewalls: This is a hardware appliance, software filter, or server plug-in. It layers security mechanisms on top of defined applications, such as FTP servers, and defines rules for HTTP connections. These rules are built for each application, to help identify and block attacks to a network.
Packet Filtering Firewalls: This filter examines every packet that passes through the network – and then accepts or denies it as defined by rules set by the user. Packet filtering can be very helpful, but it can be challenging to properly configure. Also, it’s vulnerable to IP spoofing.
Circuit-level Firewalls: This firewall type applies a variety of security mechanisms once a UDP or TCP connection has been made. Once the connection is established, packets are exchanged directly between hosts without further oversight or filtering.
Proxy Server Firewalls: This version will check all messages that enter or leave a network, and then hide the real network addresses from any external inspection.
Next Generation Firewalls (NGFW): These work by filtering traffic moving through a network – the filtering is determined by the applications or traffic types and the ports they are assigned to. These features comprise a blend of a standard firewall with additional functionality, to help with greater, more self-sufficient network inspection.
Stateful Firewalls: Sometimes referred to as third generation firewall technology, stateful filtering accomplishes two things: traffic classification based on the destination port, and packet tracking of every interaction between internal connections. These newer technologies increase usability and assist in expanding access control granularity – interactions are no longer defined by port and protocol. A packet’s history in the state table is also measured.
