Firewall Operations: How They Keep You Secure

From computers to smartphones, software developers have crafted every type of security measure possible to keep your devices safe, but the threat of malware and viruses is always looming. With products like Mcafee and Bitdefender, the tools are out there to keep your devices from being infected by the nasty threats lurking the internet. One of the best tools still used today is the firewall, an old standby for protecting your computer from oncoming threats and we will be going over how it works.

Firewalls are software programs designed to keep malicious programs, malware, and intruders from accessing your devices from the internet. To illustrate a clearer picture, think of firewalls as a water filter for your computer. It only allows safe data to come through the wall while blocking out anything dangerous from the internet. On all windows computers, dating back to Windows XP, a firewall is automatically installed to ensure that both your computer and wireless network are protected from harm.

There are two different types of Firewalls: hardware and software firewalls. All computers are equipped with software firewalls, as they are mainly equipped to block malware and other harmful intrusions. The downside to software versions, however, is that they are unable to protect multiple devices at once, meaning it benefits personal computers rather than a group. Businesses need to rely on having all their devices protected without having to pay for several versions of the same protection software. In this case, buying firewall hardware is the best option.

For multiple computer systems, including servers and private networks, there are always hardware firewalls that protect networks from outside dangers. It designed to be built into an internet router to protect your local network while offering more options compared to firewall software. For example, you can adjust who can gain access to your virtual private network through your firewall, allowing only trusted personnel in and blocking out any outside users. Thanks to the firewall hardware, your business will avoid any dangerous hacking attempts that come from a network breach.

Overall, firewalls are necessary for any person, business, or otherwise to protect themselves from any threat, from viruses to spyware. Since the Equifax breach some time ago, taking the proper security measures to ensure both your business and your customers’ information is secure is one of the most important goals for anyone to succeed. A firewall is just the first step to ensuring your peace of mind for both your computer and your business.
