5 things to know about Firewall

Things to know about firewalls

Many small businesses tend to procrastinate on proper company network protection just because they don’t know where to start. But when it comes to cybersecurity, there’s always is a risk of being too late. So, let’s get an overview of the basics. One of the first lines of defense for a company network is properly configured and installed firewalls. They are one of the oldest computer security defenses that remain a crucial foundation of network protection today. Firewalls can be software or hardware technologies that restrict incoming and outgoing network traffic through specific criteria configured by the user.


1. Firewalls must be configured properly

You have to spend time adjusting Access Control Lists (ACL) that specify what you trust into and out your network. Firewall rules typically allow you to whitelist, blacklist, or block certain websites or IP addresses.

2. Firewalls must be constantly updated

Maintaining a set of rules is one of the most important functions firewalls can have. They need to keep updated continuously to ensure that it can detect the most recent threats.

3. Firewalls are not created equal

Next-Generation Firewalls have advanced features such as anti-virus protection, web content filtering, application control, and intrusion detection/protection are available. But sometimes this will slow down your network. To avoid this, configure the firewall properly, which is quite a sophisticated task.

4. New technologies bring challenges

Considering the increased popularity of cloud solutions and Bring Your Own Device (BYOD) trend, an organization’s network perimeter is no longer well defined. Mobile devices that are not enabled with firewalls can potentially become a source of risk. The solution is to install personal network firewall software on mobile and other employee-owned devices.

5. More than just cybersecurity

Firewalls aren’t just about cybersecurity. They allow you to run and view detailed reports about network traffic, which is critical if you have to meet specific compliance requirements, such as HIPAA. It can enforce group policies by leveraging web content filtering controls and securely support remote users.

Technology is constantly evolving, offering more functionality and advanced features. It is essential for cybersecurity but adds an extra level of complexity. Protect your business reliably and focus on growth. Get in touch with Klik Solutions experts right now!
