When it comes to security, it can be an overwhelming subject to elaborate upon. There is definitely more than one potential problem we need to think about when it comes to securing our computers, our online accounts, and our wireless networks. Many security problems are caused by other people, whether it’s a company releasing software with dangerous security holes or a website getting hacked and leaking our passwords. While we can’t stop these problems from occurring, we can reduce the danger.
What is Networking?Networking is simply a process that takes places through a network which is a collection of computers, mainframes, peripherals, servers, network devices, or other devices connected to one another to allow the sharing of data. An excellent example of a network is the Internet. It connects millions of people all over the world. To the right is an example image of a home network with multiple computers and other network devices all connected to each other and the Internet.
Types of Networks
- Bus topology
- Mesh topology
- Ring topology
- Star topology
- Tree topology
- Hybrid topology
Networking Basics: Things to Know AboutComputers, mobile phones, peripherals and even IoT devices can be connected through a network. The essential networking basics are typically switches, routers and wireless access points. Through them, devices connected to a network can communicate with one another and with other networks, like the Internet.
- Switches - Switches are the foundation of most business networks. These allow devices on your network to communicate with each other, as well as with other networks, creating a network of shared resources.
- Routers - A router is a device that connects multiple devices together. Router enable all networked computers to share a single Internet connection. It basically acts as a dispatcher.
- Access Points - Access points allows networks to connect through a wireless network without cables. It primarily acts as an amplifier for your network.
Importance of FirewallA firewall is an application that controls traffic to and from a computer or network and either permit or denies communication-based on a set of rules within a security policy. Depending upon the organizational situation, a firewall is important in the following ways:
- Enables damage control
- Measures zones of risks
- Detects failure mode
- Ease of use
Key Takeaways from the Whitepaper titled, "The MUO Network Manual"
- A networking guide aims to provide with all the basics needed to deal with networking related tasks
- Wired connections still have the best bandwidth and are not affected by common household RF(radio-frequency) interference
- Firewalls are frequently used to prevent unauthorized access of private resources, like those available on a company network from other users on the Internet
- A VPN connection with a decent encryption setting can thwart any sniffing attack
