How to Use a Firewall For The Best Protection

Firewalls are one of the most used security tools to prevent malware attacks. Although they have been in existence since the 90s, courtesy of advancing technologies they have transitioned to next-generation firewalls (NCFW) which are instilled with renewed features like Deep packet inspection (DPI) and Intrusion prevention system (IPS).

The COVID blow shifted the traditional workplace to a WFH setup which made Cybersecurity more essential. In this modern scenario, the role of the firewall has been accentuated.

Firewalls act as a shield and eradicate any intrinsic or external traffic that is harmful. However, to use any firewall to the best of your ability, it is important to follow the points mentioned below. But before we understand how to use any firewall to its fullest potential first let’s understand how a firewall operates.

How a Cloud Firewall Works

Firewalls give beneficial immunity against malicious online dangers and are recognized by firms as a key tool in network safety. A cloud firewall can be integrated directly into a firm’s intrinsic infrastructure. With the development of Next-generation firewalls, companies have surpassed the requirement of physical firewall equipment. You just need to give it approval and it starts working, evading DDoS attacks.

6 Tips For Getting The Most Out Of Your Cloud Firewalls  

Here are 6 useful pieces of advice you can execute to optimize your cloud firewall

Carry Out a Robust Access Control Policy

Execute a role-based access strategy that curbs access based on the user’s role in the company. Admins can also enforce Zero Trust security regulations and give applications to applications or other cloud devices on a “need to know” principle.

Dry Run your Cloud Firewalls

Check the execution skills of your cloud firewall against enormous quantities of traffic. This will indicate if your firewall is prepared to deal with vast amounts of uncertain traffic without slowing down the system or curtailing performance.

Repeatedly Review your Firewalls Regulations

Perform systematic firewall security and study your company’s firewall security strategy. Industry restrictions alter and you must be on top of all principles to stay in the agreement. Deduce if there have been any new strategy laws or if any older rules have been appropriately identified.

Analyze Encrypted Data

All sent and received encrypted traffic should be available for examination. Some cloud firewalls have improved characteristics that enable them to evaluate encrypted traffic for malware. You could also employ an SSL forward proxy to evade malware disguised as SSL encrypted traffic from entering the company network.

Prohibit VPN Access

VPN users can present a big danger to the security of your company as they work from outside the internal cloud network. Be vigilant with permission for VPN users, and simply formulate firewall supervisions to restrict access to only what they require. You may need to separate firm LAN/WLAN networks and prohibit traffic outside the network.

Create Secure Wireless Entry for Visitors

Develop numerous secure wireless entry points to stave off any harmful attacks. Visitors to the network should have their own defined network entry and should not be lent open access to the inner network.
