Step 1 – Securing the router
Let’s hope the manufacturer built in a way to automatically update the software/firmware. If you think that sounds like a pretty insecure assumption, you are correct. Let a hacker get some malware on your device, and it can use UPnP to open you up to all sorts of evil activities. Investing in a password manager is a much better option than trying to remember a multitude of long, complex passwords.
As a workaround, you can turn off the firewall when you’re gaming or performing other tasks that require a faster connection.

Use MAC address filtering to keep unwanted devices off your network
According to a FlexJobs & Global Workplace Analytics report, there has been a 159% Increase in Remote Work Since 2005. While you might have done everything to protect your home network, your online accounts are important as well.

It is one of a set of computer security policies an organization should curate, including policies that cover acceptable use of devices and networks, mobile devices, and email. It should reflect your organization’s assets, capabilities, and vulnerabilities. Cybersecurity includes processes and technologies that aim to protect data, software, and hardware data from attacks that could result in damage or unauthorized access. Cybersecurity usually focuses on high level threats to government and military institutions, and enterprise-level civilian institutions such as banks and health care organizations.

After all, not everyone in your organization needs to be able to physically or electronically access everything on your network. You must also consider the physical security of the various devices, servers and systems that are used to power and maintain your network. In order to effectively implement and maintain secure networks, it’s important to understand the common vulnerabilities, threats and issues facing IT professionals today. While some can be fixed fairly easily, others require more involved solutions.
Networks follow protocols, which define how communications are sent and received. Each device on a network uses an Internet Protocol or IP address, a string of numbers that uniquely identifies a device and allows other devices to recognize it.
