Firewall Intrusion Detection And Honeypot Using Raspberry Pi

A firewall protects networked computers from intentional hostile intrusion that could compromise confidentiality or result in data corruption or denial of service. It may be a hardware device or a software program running on a secure host computer. It must have at least two network interfaces, one of the network it is intended to protect, and one for the network it exposed

A firewall is a system designed to prevent unauthorized access to or from a private network. You can implement a firewall in either hardware or software form, or a combination of both. Firewalls prevent unauthorized Internet users from accessing private networks connected to the Internet, especially intranets. All messages entering or leaving the intranet (i.e., the local network to which you are connected) must pass through the firewall, which examines each message and blocks those that do not meet the specified security criteria. In protecting private information, a firewall is considered a first line of defense; it cannot be the only line of defense. Firewalls are generally designed to protect network traffic and connections, and therefore do not attempt to authenticate individual users when determining who can access a particular computer or network. Furthermore, firewalls can be set up to prevent employees from accessing certain content or downloading

The Firewall systems will be used to prevent scanning activity as well as blocking malicious IPs from entering the network. This is critical because being able to block this type of traffic can save a network and the people who watch it a lot of time on incident investigations. When hackers are scanning a network they are looking for reply backs from any port(s) that will respond. This can help them finger print a system and by knowing what is on a network they can use this information for crafting attacks. Once this is identified by a security team they can block the intruding IP at the firewall. This will prevent all traffic coming and going to the suspicious IP in question.

Firewall is a combination of hardware and software that isolates an organization's internal network from the Internet at large, allowing specific connections to pass and blocking others. Network security system that monitors and controls the incoming and outgoing network traffic based on predetermined security rules. The term "firewall" it is also known in other disciplines, and in fact, these terms are not only concerned with network terminology. We also use a firewall, for example, for separating the garage from the house, or a separate apartment with one other apartment. In this case, a firewall is a barrier (barrier) against fire is meant to slow the spread of flames in case of fire before firefighters arrived to extinguish the fire. Another example of a firewall can also be found on vehicles, where the firewall separates the passenger compartment and the engine compartment.

A Firewall basically prevents the private network connected to the internet from being accessed by unauthorized user and therefore handles the traffic of internet. Hardware and software firewalls are the types of this network security system. It examines the each data in the network and blocks the data which is not valid and are from unauthorized user. We will discuss here only software firewalls.

Information play an essential role in everywhere. For a company, in order to run the company well, information management is a necessary skill, and leaking information, odds are , causes significant damage to the company. Even though a private network will not have as great damage as an organization, people like to keep their privacy. Therefore, the security of a home network is as important as the security of a company, and it is more universal. Hence this article will present how to built a

Today’s “Cyber Domain” is growing rapidly to keep pace in an ever more competitive world. Businesses are adopting new ways of doing Business due to the increasing dependency on networked communication devices, network access points and cloud-based services. Building a sophisticated Computer Network Defense (CND) plan in order to protect, analyze, monitor, respond and detect unauthorized access to computer networks is becoming increasingly difficult. Sophisticated cyber criminals are taking advantage of rapid business digitization and evolving IT

Software applications undergo software development life cycle (SDLC) which involve requirement gathering, system design, application development, quality analysis and maintenance. Different strategies such as extreme programming, agile, and scrum can be employed to achieve efficient software development and maintenance plan. System analysis and design models built using object oriented methodology and UML help in understanding the purpose of software application and act as blueprint to implement the software.
