Firewall defined

A firewall is a network security device that monitors incoming and outgoing network traffic and permits or blocks data packets based on a set of security rules. Its purpose is to establish a barrier between your internal network and incoming traffic from external sources (such as the internet) in order to block malicious traffic like viruses and hackers.

How does a firewall work?
Firewalls carefully analyze incoming traffic based on pre-established rules and filter traffic coming from unsecured or suspicious sources to prevent attacks. Firewalls guard traffic at a computer’s entry point, called ports, which is where information is exchanged with external devices. For example, “Source address 172.18.1.1 is allowed to reach destination 172.18.2.1 over port 22."

Think of IP addresses as houses, and port numbers as rooms within the house. Only trusted people (source addresses) are allowed to enter the house (destination address) at all—then it’s further filtered so that people within the house are only allowed to access certain rooms (destination ports), depending on if they're the owner, a child, or a guest. The owner is allowed to any room (any port), while children and guests are allowed into a certain set of rooms (specific ports).

Firewall Logs Monitoring

The Need for Comprehensive Firewall Logs Analyzer Application
Just deploying the necessary security tools (Firewall and other end security devices) in itself will not secure your network, but the security data from the tools need to be analyzed and the extracted security information should be reported or alerted to ensure that the network is secured. Hence, the analysis of firewall syslogs and other security device logs is vital to network security.

Firewall logs analysis reveals a lot of information about the security threat attempts at the periphery of the network and on the nature of traffic coming in and going out of the firewall. The analyzed firewall logs information provides real-time information to the Administrators on the security threat attempts and so that they can swiftly initiate remediation action. It allows you to plan your bandwidth requirement based on the bandwidth usage across the firewalls. Firewall log monitoring plays an important role in business risk assessment. Analyzing firewall traffic logs is vital to understand the network and bandwidth usage. Firewall Analyzer, a  firewall monitoring tool, offers many features that help in collecting, analyzing and reporting on firewall logs.

Managed Firewall Services Market

The managed firewall is a service provided by managed security service providers (MSSPs) to monitor network traffic and address security threats in organizations. Managed firewall service providers embed firewall security throughout the network and provide services such as configuration, administration, monitoring, support, and installation of the firewall system. Managed firewall solutions integrate security services into products resulting in a scalable, manageable, and transparent network infrastructure. Managed firewall services are either standalone or integrated with other security management offerings. Managed firewall services secure business from threats, malware, spam, cybercriminal activities, and viruses. Threat detection and remediation, real-time security monitoring, management, and analysis of firewall logs are a few of the key tasks performed by the managed firewall security service providers within organizations.

Managed firewall service providers to reduce IT costs by providing end-to-end firewall management services. Managed firewall services also help organizations meet regulatory compliance requirements such as PCI DSS, ISO27001, etc. Managed security services involve services such as consulting, deployment and integration, and monitoring and maintenance. Further, they also include application control i.e. blocking applications and web content filtering, which means blocking of access to malicious websites. A rise in the cloud deployment model, an increase in investment in IT infrastructure development, and the growing number of cyber-attacks with day-to-day technological advancements are the key factors driving the growth of the managed firewall services market. Major cyber-attacks in 2017, such as WannaCry and Petya further indicate the need for managed firewall services.

Types of firewalls

Other types of firewalls include packet-filtering firewalls, stateful inspection firewalls, proxy firewalls and next-generation firewalls (NGFWs).

• A packet-filtering firewall examines packets in isolation and does not know the packet's context.
• A stateful inspection firewall examines network traffic to determine whether one packet is related to another packet.
• A proxy firewall (aka application-level gateway) inspects packets at the application layer of the Open Systems Interconnection (OSI) reference model.
• An NGFW uses a multilayered approach to integrate enterprise firewall capabilities with an intrusion prevention system (IPS) and application control.
• A personal firewall is a software used to protect a single internet-connected computer from attacks, as opposed to a multitude of devices.
