How to choose the right firewall

We have plenty of vendor-specific training available in our vast training library, so you can use Juniper, CheckPoint, Palo Alto or Palo Alto firewalls. You might also consider CompTIA Security+, Certified Ethical Hacker or (ISC.2) CISSP certifications.
The right firewall can make a big difference in opening up your critical data to the Internet and protecting your internal network and intellectual properties. Your firewall is the virtual wall that protects your network resources from the Internet. Unidentified malicious traffic and data breaches can lead to millions of dollars in losses. Firewalls prevent DoS attacks, block unauthorized access to the network, and filter network traffic.
These questions will help you narrow down your options as you choose the firewall that is right for YOU.
Do you need remote access for home-based users?

While you can buy a secondary system or VPN solution to your network, a hardware firewall solution that includes VPN and its architecture is more cost-effective is far better.
How secure are you against DoS/DDoS attacks?
Over the past few years, there have been major Distributed Denial of Service attacks (DDoS), targeting large businesses. As attackers add more zombies to their botnet, DDoS attacks are becoming more common. DDoS attacks are launched without any warning or notice. An abrupt drop in bandwidth or performance on public-facing servers or IT resources is the only alert.
These attacks can be detected and stopped by a firewall. To target suspicious traffic, you can combine the router with intrusion detection systems. A firewall can stop an attack from beginning to end, but it is only a basic tool. Don’t forget to configure your defenses correctly. Attackers will continue their attack. Make sure you have DDoS mitigation and detection in your firewall.
Are Masquerade Ports Critical for Critical Services Required?
Many services use a standard port. However, you can use an alternate port to avoid attacks against a particular service. Administrators of Windows are used to opening RDP (port 3389). Hackers often use this port to probe for security holes in the network. If administrators still require RDP from outside resources, the solution is to change the port that connects with the servers. This is done on the server, and is “allowed by the firewall.” This can be done using more ports than RDP. If the service isn’t critical and doesn’t require a standard port, you can increase security by choosing an alternate port and configuring it on the router.
The router will forward traffic to an alternative port and filter any incoming requests for the standard port. A firewall has one of the greatest advantages: filtering traffic.
How do you know when an attack occurred?
How do you know if your firewall is blocking an incoming attack? Although you can rely upon the firewall to stop an attack from occurring, it is equally important to know when one has occurred or is currently in progress. A firewall can alert a group of administrators that a critical attack is underway.
Once an administrator is alerted, router logs and firewall logs can be used to determine the source of the attack. The administrator can quickly stop an attack from causing major downtime to the business by setting up the right firewall.
