A firewall, sometimes known as a packet filter, is a software program that runs on a computer or server to prevent harmful malware from entering and allowing or denying data packets based on defined security criteria. Consider, for example, a network firewall that separates networks.
A next gen firewall, often known as NFV or future-generation firewall, is a network security system that goes beyond the capabilities of a basic firewall. Future-generation firewalls provide features including cloud-delivered threat intelligence, app awareness and control, and integrated intrusion prevention.
Virtualization domains that are firewall-protected can use integrated access control, malware persistence, and User Account Control (UAC) to improve security. They include additional protection against contemporary risks such as sophisticated malware and application-layer attacks, incorporated intrusion prevention, threat intelligence providers, and account takeover
A firewall is a computer software that monitors and controls network traffic in accordance with rules via packet inspection and filtering. The following table lists some of the ways that traditional firewalls differ from NGFWs.
There are five things to consider while selecting a next-generation firewall:
Extensive Network Visibility
Users should have access to all of the data, including threat actions on networks and devices, as well as live applications and internet sites.
Quick Detection Time
The average blackout period is around 100 to 200 days. Fortunately, a next-generation firewall is anticipated to react in milliseconds and discover breaches promptly, allowing it to avoid damage.
Seamless Integration
A next-generation firewall must be able to communicate with other technologies as well as automate security processes such as impact analysis, policy management, and optimization.
Advanced Security and Breach Prevention
The primary responsibility of an NGFW is to keep your network and organization secure. It should include advanced capabilities that can identify sophisticated malware swiftly, IPS built-in to detect stealthy threats, a world-class threat intelligence firm, and URL filtering abilities that enforce URLs’ norms.
Flexible Management Options
Your next-gen firewall should be able to meet your exact requirements while also recording each usage scenario and providing a range of bandwidth alternatives.
The Benefits of a Next-Generation Firewall
Gartner discovered that NGFW outperformed traditional firewalls in malware detection and blocking, allowing for improved network and company security.
DDoS attacks may inflict substantial damage to the Internet as a whole, and we think that taking certain precautions now might help to reduce future DDoS assaults. An updated network architecture will be far more resistant and safe against sophisticated attacks (APT).
The terms “cloud-based firewall” and “shared services capability” have no technical significance. Nonetheless, NFVs can be used to improve basic firewall protection and management.
