The Importance of Firewalls

While antivirus software is an important part of efficient protection against viruses and harmful information on the internet, it is not adequate in and of itself! Antivirus software use built-in heuristic algorithms to identify threats and quarantine them. However, no operating system can ever be entirely safe from a cyber assault.

Firewalls safeguard a network’s perimeter by monitoring and filtering all network traffic, both desirable and unwanted. They establish barriers to deter prospective attackers and harmful applications, protecting the network from illegal access, after undesirable traffic has been discovered.

Users may also customize their firewall’s security settings to meet their personal or business privacy demands. Excessively restrictive settings may prevent a person from accessing the internet completely.

A firewall shouldn’t be your only consideration for securing your home network. It’s important to make sure all of your internet-enabled devices have the latest operating system, web browsers, and security software. You also should secure your wireless router. This might include changing the name of your router from the default ID and password it came with from the manufacturer, reviewing your security options, and setting up a guest network for visitors to your home.

Without a firewall, potential attackers can simply identify your computer as a susceptible target, enter your network covertly, and undermine the system’s security.

Microsoft Vulnerability Reports in 2020

Windows 10 was once deemed the most secure OS. With over 1 billion users utilizing the system, the highest priority has to be its security. However, over the years, it continues to experience vulnerabilities.

And it’s not just Windows 10, other Microsoft products, such as its browsers, Edge and Internet Explorer had issues with flaws. Sources say that in 2020, exposures reached to 1,268. This was the highest it has been, with 132 of those deemed critical.

What can help?

The biggest reason for the vulnerabilities involved admin rights. When others are given rights, the risk of attacks heighten. Removing them can lower the risk.

While there were a wide number of vulnerabilities found in various Microsoft products in 2020, for the first time, Elevation of privilege, which occurs when an application gains rights or privileges that should not be available to them, accounted for the largest proportion. It almost tripled in number year over year from 198 in 2019 to 559 in 2020, making up 44% of all Microsoft vulnerabilities in 2020.

Online Privacy and What that Entails

Companies everywhere are utilizing information given by online users every day. This comes in several ways, such as advertisements and cookies. By collecting this information, companies have opportunities to sell it or use it to their own advantages.

While the majority of this collection is harmless, users often do not know what they are giving online. To heighten the online privacy, here are a couple ways without tracking you.

Virtual Private Networks, or VPN’s, allow users to anonymously surf the web. This handy software gives no location detection, so companies online can’t track information. Prices for VPN’s are cheap and available everywhere.

Check your privacy settings on your computer, phone, or other devices. Some include ‘Incognito Mode’ which doesn’t save any information to your history browsing, nor login credentials. It’s also important to not allow companies to use tracking while using their applications.
