Comparison between Next Gen Firewall with Traditional Firewall
There is no one method to getting the robust security you require in our contemporary era of systems, networks, people, and clouds. Your organisation must implement various functions, processes, and policies to cope with cyber threats while adhering to cybersecurity best practices.
Use Securiwiser to add more security layers. A security monitoring application called Securiwiser assesses the cybersecurity posture of your business, highlighting vulnerabilities and exploits on a simple-to-read dashboard. It continuously monitors your network and cloud security and looks for viruses, incorrect setups, unusual port behaviour, and much more.
History of firewalls
The Digital Equipment Corporation developed the first firewalls in the late 1980s (DEC). The original version of the firewall could function on the Physical layer, Data Link Layer, Network Layer, and Transport Layer of the OSI (Open Systems Interconnection) model. This firewall was primary, but it could examine the characteristics of each packet of data travelling over the network and determine if it complied with any defined rules. The package was discarded if it didn’t comply with the regulations; else, it was permitted to pass. It was so simple and easy to handle, belied how reactive it was, making it vulnerable to cunning hackers or automated programmes.
The third generation of firewalls, also known as next gen firewall Malaysia, which most enterprises and internet users currently use, was created as a result of significant breakthroughs in firewalls during the next ten years. However, before Palto Alto Networks developed the first NGFW in 2008, next-generation firewalls had just begun probing deeper into Transport layer headers and had not yet developed into the full mode of security we are familiar with today.
It controls the flow of traffic entering and leaving your network, like all firewalls, using information from ports, protocols, and policies, as well as the source and destination IP addresses.
Traditional firewalls can do the following:
- Unbiased inspection Most conventional firewalls carry out stateless checks and are uninformed about sessions.
- Packet filtering ensures that incoming and outgoing packets are examined before being allowed to pass. Instead of being transmitted, packages that don’t comply with the filter’s requirements are discarded.
- When users use public networks, such as the internet, VPN support helps keep private networks safe.
Although their name implies, they are not seen as the most sophisticated security firewalls now accessible since they are restricted to evaluating the network layer and transport layer of a packet to make choices.
This takes us to the most effective firewall defence currently available: next-generation firewalls.
Next-generation firewalls (NGFWs)
The main tasks of old firewalls are usually included in next gen firewall Malaysia (NGFWs). Still, they also often contain a lot of extra features and complexity to defend networks and systems from attacks and provide you with more layers of protection.
They have a lot of application-level controls, as noted above, and go beyond the static inspection that traditional firewalls are frequently restricted to.
- Deep Packet Analysis (DPI), which provides a thorough inspection of the message’s contents, including its source, allows the NGFW to understand the full context of each packet. Standard packet filtering scans the header of a package.
- Application awareness enables organisations to detect non-business apps and impose program-specific policies, such as outright disabling an application, because they can inspect the application layer.
- NGFW can actively identify and stop intrusions with the help of an IPS, which also drops malicious packets and logs or blocklists IP addresses.
- Simplified architecture and single console access provide quick access and streamline the management and upgrading of security protocols, saving time and enhancing efficiency, which is essential in cybersecurity.
In contrast to classic firewalls, where complexity will slow down everything, next-generation firewalls offer several advantages, including maintaining network speed and high availability despite the complexity of their jobs and configurations.
Differences Between Traditional and Next-Generation Firewalls
|Parameter||Traditional Firewall||New Generation Firewall|
|Working Layer||Traditional firewalls work from Layer 1 to Layer 4||NGFWs work through Layers 2 to Layer 7|
|Packet Filtering||In a traditional firewall, packet filtering allow an administrator to review both ingoing and outgoing packets before they are allowed to pass through the networks||Deep Packet Filtering (DPI) inspects the contents of each packet, including its source, unlike standard packet filtering, which only reads the header of the packet.|
|Stateful or stateless inspection||In a stateless inspection, a firewall inspects each packet individually based on static information like the source and destination. On the other hand, stateful firewalls look at the overall context of the network connection and provide greater security.||All NGFWs conduct stateful packet inspections, but take it one step further.|
|Virtual Private Networks (VPNs)||Traditional firewalls allow access to VPN to keep the private network secure when using the internet||NGFWs also allow access to VPNs to keep the private network secure when using the internet|
|Application awareness||It do not have applications awareness and do not allow admits to set specific rules for different applications.||NGFWs possess application awareness and enables organisations to set application-specific rules|
|Intrusion Prevention System (IPS)||Traditional firewalls do no provide IPS||NGFWs have IPSs, which are capable of actively blocking intrusions and blacklisting all future traffic from a malicious source|
|Threat Intelligence||It works on the basis of rules set by the administrator, and thus do not have threat intelligence.||NGFWs are constantly learning and updating their database of malicious software and threats offering greater protection every time a new threats tries to breach the system|
|Reporting||Traditional firewalls only provide standard reports||NGFWs offer organisations to pull customised reports with near real-time detail and plenty of reporting options|
Data more secure
Traditional firewalls may offer your network systems some basic security. Still, the unique requirements and delicate nature of running a business demand more profound protection, which only a next-generation firewall can deliver. Even a modest data breach can cause your consumers to lose faith in your company. Your customers need to know they can trust you with their data. Because they lack proper security measures, hackers target small businesses. If you haven’t already, this is a critical factor in your decision to upgrade to a next-generation firewall. But not all NGFWs will work for every organisation, as no two are the same.
