Firewall Protect Your Company

As more of the world becomes familiar with how the internet works, there’s a proportional increase in the number of people who use it for malicious purposes. Protecting your company against cybercriminals and pranksters may appear to be above and beyond your expertise. However, using a firewall to protect your online presence is a very simple way to reduce the amount of time and brain space you need to dedicate to cybersecurity. So, what does a firewall protect your company against and what won’t it protect against? In this article, we’ll find out.

What Is A Firewall?

A firewall is a security system that monitors the incoming and outgoing online traffic affecting your information technology network. The firewall blocks or allows packets of information according to a prescribed set of security rules. Ultimately, a firewall is employed to prevent malicious actors or applications from accessing your internal network.

Types Of Firewalls

There are two main types of firewalls: hardware and software.

Hardware Firewalls

Hardware firewalls are built into the components that make up your computing network. This includes servers, computers and all other physical computing constituents. Hardware firewalls typically don’t require any setup and begin working when the equipment is powered up. Hardware firewalls assess incoming data packets and allow them or exclude them according to the security protocols they’re programmed to follow.

Software Firewalls

Software firewalls are third-party applications that are added to provide extra protection to the computing network. Software firewalls need to be installed in a system and typically require some type of manual setup. Software firewalls assess outgoing traffic and can also reduce the spread of malicious code within your network.

Benefits Of Firewalls

Firewalls have been used since the advent of the internet and are constantly being upgraded to keep up with the evolution and expansion of online threats. There are many benefits to using firewalls and most experts would say they are absolutely necessary.

Prevent Undesirable Network Access

If the wrong parties are allowed access to your network, the damage they can cause is only limited by their skill and imagination. Firewalls are used to prevent malicious actors from gaining access to a system and causing problems.

Minimize Exposure To Digital Threats

Firewalls can prevent the traffic that carries digital threats from getting into your systems. They can be used to increase the resilience of your system while also limiting any damage that might be caused by these digital threats.

Protect Software And Hardware Integrity

Firewalls can be used to minimize the damage that can be caused to both software and hardware by malicious actors. They can provide security against data breaches and thereby increase privacy.

What A Firewall Won’t Protect Against

Although firewalls play a major role in protecting computer networks, they aren’t able to protect your systems against every threat.

Installation Of Malware

Although firewalls may be able to identify traffic that originates from suspicious origins, malware needs to be installed, often by an internal user, for it to be able to take over a system. If you or someone using your network inadvertently installs malware, it’s too late for the firewall to help you. This would be where antivirus software would need to be employed.

Spoofing

Spoofing is when a malicious actor imitates a legitimate user to gain access to a system. The firewall won’t recognize a malicious actor if they’re identified as legitimate. Spoofing can occur through emails, email attachments and via spoofed websites set up to look legitimate. Because spoofing usually depends on a legitimate user making a mistake, the firewall is typically overridden.

Conclusion

Although firewalls are powerful forms of network protection, they can’t protect your network against everything. While you most definitely should be using both hardware and software firewalls, you’ll need to bolster them with other forms of digital protection. This should be combined with the knowledge to carry out best practices and avoid being tricked by malicious actors.
