Cyber risks are growing rapidly as technology develops. For both large and small businesses, it has become essential to protect the most vital corporate assets, i.e., data. A firewall serves as the first line of defense against any cyberattack, and if it is robust enough, it can thwart the attack at the point of entry. Let’s dive deep and understand what exactly is a firewall and the reasons why you should use a firewall.
What is Firewall?
A firewall is the first layer of network security that is used to filter and block incoming and outgoing data. A firewall can be hardware or software depending on the size of the network. Most of the operating systems of mobiles and computers have a basic firewall application pre-installed in them, but they are not as effective as a dedicated firewall application or hardware installed in the network for protection.
Firewalls are capable of filtering the incoming data based on IP and protocol configuration. It also blocks the traffic coming from an unknown IP address and also protects the network from Denial of Service (DoS) and Distributed Denial of Service (DDoS) attacks.
Here are the 5 reasons why you should use a firewall for your business:
Unauthorized individuals cannot access your network because of firewalls. However, you can also prevent your users from accessing a certain set of websites. This is helpful if you want to stop your staff from visiting improper websites that might download harmful software while they are on your network. For instance, you might forbid your staff from visiting websites that promote gambling or pornography. You can also prevent users from accessing shady online stores or any other website that might provide unlawful downloads. By doing this, you may limit network exposure to websites that can encourage dangerous malware to infiltrate your systems and manage what your employees see when they use their work computers.
Network bandwidth can be managed with the use of firewalls. You can restrict the amount of bandwidth made available for particular categories of data using a firewall. This could be achieved by restricting the bandwidth made available for streaming media files or other types of content. Only particular types of traffic may be configured to pass through a firewall to access the Internet. You might, for instance, want to block access to some websites while allowing users to connect to your business printer.
Firewalls don’t necessarily have to be software, as was previously mentioned. Most households have hardware firewalls that are incorporated into the router. Using the router administrator login information, you may access these firewalls (be careful to change the default password first). Once you’ve logged in, you should be able to inspect the settings and make any necessary changes. Sometimes you’ll need to make adjustments, especially if you’re using a games console to play online. For instance, one typical solution for online gaming connectivity troubles on the PlayStation 3 and PlayStation 4 is to change the NAT type. Before you begin saving any changes, make sure you acquaint yourself with the settings by reading the router’s documentation. For big organizations, firewalls are mostly hardware devices as the computer network of those organizations is huge and needs extra safety and configurations.
Conclusion:
In light of all of this, it is important to consider what a firewall cannot achieve. Malware is a term we’ve already used, but it covers the full range of Trojans, viruses, worms, and other malicious software. Firewalls are unable to stop malware such as viruses, worms, keyloggers, and other threats. Consequently, an anti-virus tool must be employed in addition to a firewall.
