In this digitally connected world, one technology stands at the forefront of protecting businesses from cyber threats: Firewall. When discussing Firewall, we commonly encounter two main types: Traditional Firewall and Next-Generation Firewall (NGFW).
This article explores the fundamental differences between Traditional Firewall and Next-Generation Firewall (NGFW), helping you determine which offers the best protection for your business.
What is a Firewall?
A firewall is a security system designed to protect a computer network from attacks that could compromise the integrity, confidentiality, or availability of data. In the late 1980s, Digital Equipment Corporation (DEC) developed the first firewall as an initial step in safeguarding networks.
Firewall operates on the first four layers of the OSI model: the Physical Layer, Data Link Layer, Network Layer, and Transport Layer. Early-generation firewall, though simple, were effective in scrutinizing every data packet passing through the network to ensure compliance with configured rules. If the package meets the rules, permission is granted; otherwise, the packet is rejected.
However, despite their effectiveness, these early-generation firewall tend to be reactive and vulnerable to clever tactics used by hackers or bots.
Over time, there have been significant developments in firewall technology, leading to the emergence of Next-Generation Firewall (also known as third-generation firewall), which are now widely adopted by businesses and internet users.
8 Differences between Traditional Firewall and Next-Generation Firewall (NGFW)
Understanding the distinctions between Traditional Firewall and Next-Generation Firewall (NGFW) is crucial for safeguarding business networks and data against increasingly sophisticated cyber-attacks. Let's delve into the significant differences between the two:
1. Work Layer
Traditional Firewall: Operate from Layer 1 to Layer 4
NGFW: Function across Layer 2 to Layer 7
2. Packet Filter
Traditional Firewall: Allow administrators to review incoming and outgoing packets before passing through the network
NGFW: Utilize Deep Packet Filtering (DPI) to examine the contents of each packet, including its source, offering a more thorough analysis than standard packet filters that only read packet headers
3. Stateful or Stateless Inspection
Traditional Firewall: Inspect each packet individually based on static information
NGFW: Perform stateful packet inspection, considering the context of the entire network connection to provide enhanced security
4. Virtual Private Networks (VPN)
Traditional Firewall: Allow access to VPN to maintain security for private networks using the internet
NGFW: Like Traditional Firewall, also allow access to VPN for securing private networks
5. Application Awareness
Traditional Firewall: Lack application awareness, preventing administrators from setting custom rules for different applications
NGFW: Possess application awareness, enabling companies to establish rules specific to certain applications
6. Intrusion Prevention System (IPS)
Traditional Firewall: Do not provide IPS
NGFW: Equipped with IPS, capable of actively blocking intrusions and blacklisting future traffic from malicious sources
7. Threat Intelligence
Traditional Firewall: Rely on rules set by administrators, lacking threat intelligence
NGFW: Continuously upgrade and update database software to adapt to new and sophisticated threats
8. Reporting
Traditional Firewall: Provide only standard reports
NGFW: Produce various reporting options that can be accessed in detail and in real-time
While traditional firewall offers basic protection, the need for deeper security and responsiveness to evolving threats strengthens the case for adopting Next-Generation Firewall (NGFW).
