- The firewall, IPS, and IDS differ in that the firewall acts as a filter for traffic based on security rules, the IPS actively blocks threats, and the IDS monitors and alerts on potential security breaches. A firewall sets the boundaries for network traffic, blocking or allowing data based on predetermined protocols.

Firewall vs Antivirus Explained. What’s the difference between firewall and antivirus software? Firewalls focus on controlling network traffic and preventing unauthorized access. By contrast, antivirus programs target and eliminate threats at the device level. More specifically, their key differences include:

Packet-filtering firewallswork on the network layer of the OSI model, examining each incoming and outgoing packet’s header information (such as source and destination IP addresses, port numbers, and protocols) to determine whether the packet should be allowed or blocked based on preconfigured rules.
Stateful inspection firewallsoperate on the transport layer of the OSI model. They maintain a state table to track the state of each active connection, which allows them to inspect both packet headers and payloads. Stateful inspection firewalls can filter packets based on their context, providing more robust security than packet-filtering firewalls...
Application-layer firewalls, also known as proxy firewalls, operate at the application layer of the OSI model. They act as intermediaries between clients and servers, intercepting and analyzing application-level protocols and data to enforce security policies.
Next-generation firewalls (NGFWs)are an evolution of traditional firewalls that offer a more comprehensive and integrated approach to network security. In addition to basic firewall capabilities, NGFWs provide advanced threat protection features like intrusion prevention systems (IPS), deep packet inspection, user and application identification, an...
Cloud-based firewalls, also known as Firewall-as-a-Service (FWaaS), are a type of firewall hosted in the cloud and delivered as a subscription-based service. They provide centralized management, configuration, and maintenance of security policies across distributed networks, devices and users.
Circuit-level gateway firewallsoperate at the session layer of the OSI model. They establish a connection between the client and the server, acting as a relay for data packets. This type of firewall filters traffic based on the state of the TCP handshake, ensuring that the session is legitimate before allowing data to flow between the two parties.
Network firewallsare hardware or software-based solutions that provide security at the perimeter of a network. They act as a barrier between an organization’s internal network and the outside world, filtering and inspecting data packets based on predefined rules.
Host-based firewallsare software applications installed on individual devices, such as laptops, desktops, or servers. They filter incoming and outgoing traffic on a per-device basis and can be configured with specific rules for each device, providing a more granular level of control.
There is no one-size-fits-all solution when it comes to firewalls. The type of firewall you choose will depend on your organization’s specific needs, its network complexity, and the types of threats you want to guard against. By understanding the different types of firewalls, their advantages and disadvantages, and their use cases, you can make an ...
The major distinction is that a firewall blocks and filters network traffic, but an IDS/IPS detects and alerts an administrator or prevents the attack, depending on the setup. A firewall permits traffic depending on a set of rules that have been set up. It is based on the source, destination, and port addresses.
