to the access control list (ACL) entries. This entry identifies specific types of packets that can be sent to each host and all other traffic is blocked. It will also check the MAC address of a requester to determine whether the device being used are able to make the connection is authorized to access the data or not.
Hybrid firewalls
It is a type of firewalls which combine features of other four types of firewalls. These are elements of packet filtering and proxy services, or of packet filtering and circuit gateways.
2. Development Era:
Firewall can be categorised on the basis of the generation type. These are-
First Generation
Second Generation
Third Generation
Fourth Generation
Fifth Generation
First Generation:
The first generation firewall comes with static packet filtering firewall. A static packet filter is the simplest and least expensive forms of firewall protection. In this generation, each packet entering and leaving the network is checked and will be either passed or rejected depends on the user-defined rules. We can compare this security with the bouncer of the club who only allows people over 21 to enter and below 21 will be disallowed.
Second Generation:
Second generation firewall comes with Application level or proxy servers. This generation of firewall increases the security level between trusted and untrusted networks. An Application level firewall uses software to intercept connections for each IP and to perform security inspection. It involves proxy services which act as an interface between the user on the internal trusted network and the Internet. Each computer communicates with each other by passing network traffic through the proxy program. This program evaluates data sent from the client and decides which to move on and which to drop.
Third Generation:
The third generation firewall comes with the stateful inspection firewalls. This generation of the firewall has evolved to meet the major requirements demanded by corporate networks of increased security while minimizing the impact on network performance. The needs of the third generation firewalls will be even more demanding due to the growing support for VPNs, wireless communication, and enhanced virus protection. The most challenging element of this evolution is maintaining the firewall's simplicity (and hence its maintainability and security) without compromising flexibility.
Fourth Generation:
The fourth generation firewall comes with dynamic packet filtering firewall. This firewall monitors the state of active connections, and on the basis of this information, it determines which network packets are allowed to pass through the firewall. By recording session information such as IP addresses and port numbers, a dynamic packet filter can implement a much tighter security posture than a static packet filter.
Fifth Generation:
The fifth generation firewall comes with kernel proxy firewall. This firewall works under the kernel of Windows NT Executive. This firewall proxy operates at the application layer. In this, when a packet arrives, a new virtual stack table is created which contains only the protocol proxies needed to examine the specific packet. These packets investigated at each layer of the stack, which involves evaluating the data link header along with the network header, transport header, session layer information, and application layer data. This firewall works faster than all the application-level firewalls because all evaluation takes place at the kernel layer and not at the higher layers of the operating system.
3. Intended deployment structure:
Firewall can also be categorized based on the structure. These are-
Commercial Appliances
It runs on a custom operating system. This firewall system consists of firewall application software running on a general-purpose computer. It is designed to provide protection for a medium-to-large business network. Most of the commercial firewalls are quite complex and often require specialized training and certification to take
full advantage of their features.

Office Home Office
The SOHO firewall is designed for small office or home office networks who need protection from Internet security threats. A firewall for a SOHO (Small Office Home Office) is the first line of defence and plays an essential role in an overall security strategy. SOHO firewall has limited resources so that the firewall product they implement must be relatively easy to use and maintain, and be cost-effective. This firewall connects a user's local area network or a specific computer system to the Internetworking device.
Residential Software
Residential-grade firewall software is installed directly on a user's system. Some of these applications combine firewall services with other protections such as antivirus or intrusion detection. There are a limit to the level of configurability and protection that software firewalls can provide.
4. Architectural Implementation
The firewall configuration that works best for a particular organization depends on three factors: the objectives of the network, the organization's ability to develop and implement the architectures, and the budget available for the function.
There are four common architectural implementations of firewalls:
Packet-filtering routers
Packet filtering firewall is used to control the network access by monitoring the outgoing and incoming packets. It allows them to pass or halt based on the source and destination IP addresses, protocols and ports. During communication, a node transmits a packet; this packet is filtered and matched with the predefined rules and policies. Once it is matched, a packet is considered secure and verified and are able to be accepted otherwise blocked them.
Screened host firewalls
This firewall architecture combines the packet-filtering router with a separate and dedicated firewall. The application gateway needs only one network interface. It is allowing the router to pre-screen packets to minimize the network traffic and load on the internal proxy. The packet-filtering router filters dangerous protocols from reaching the application gateway and site systems.
Dual-homed host firewalls
The network architecture for the dual-homed host firewall is simple. Its architecture is built around the dual-homed host computer, a computer that has at least two NICs. One NIC is to be connected with the external network, and other is connected to the internal network which provides an additional layer of protection. With these NICs, all traffic must go through the firewall in order to move between the internal and external networks.
The Implementation of this architecture often makes use of NAT. NAT is a method of mapping assigned IP addresses to special ranges of no routable internal IP addresses, thereby creating another barrier to intrusion from external attackers.
Screened Subnet Firewalls
This architecture adds an extra layer (perimeter network) of security to the screened host architecture by adding a perimeter network that further isolates the internal network from the Internet. In this architecture, there are two screening routers and both connected to the perimeter net. One router sits between the perimeter net and the internal network, and the other router sits between the perimeter net and the external network. To break into the internal network, an attacker would have to get past both routers. There is no single vulnerable point that will compromise the internal network.
VPNs
A VPN stands for virtual private network. It is a technology which creates a safe and an encrypted connection on the Internet from a device to a network. This type of connection helps to ensure our sensitive data is transmitted safely. It prevents our connection from eavesdropping on the network traffic and allows the user to access a private network securely. This technology is widely used in the corporate environments.
A VPN works same as firewall like firewall protects data local to a device wherever VPNs protects data online. To ensure safe communication on the internet, data travel thr
ough secure tunnels, and VPNs user u

authentication method to gain access over the VPNs server. VPNs are used by remote users who need to access corporate resources, consumers who want to download files and business travellers want to access a site that is geographically restricted.
Intrusion Detection System (IDS)
An IDS is a security system which monitors the computer systems and network traffic. It analyses that traffic for possible hostile attacks originating from the outsider and also for system misuse or attacks originating from the insider. A firewall does a job of filtering the incoming traffic from the internet, the IDS in a similar way compliments the firewall security. Like, the firewall protects an organization sensitive data from malicious attacks over the Internet, the Intrusion detection system alerts the system administrator in the case when someone tries to break in the firewall security and tries to have access on any network in the trusted side.
Intrusion Detection System have different types to detects the suspicious activities-
1. NIDS-
It is a Network Intrusion Detection System which monitors the inbound and outbound traffic to and from all the devices over the network.
2. HIDS-
It is a Host Intrusion Detection System which runs on all devices in the network with direct access to both internet and enterprise internal network. It can detect anomalous network packets that originate from inside the organization or malicious traffic that a NIDS has failed to catch. HIDS may also identify malicious traffic that arises from the host itself.
3. Signature-based Intrusion Detection System-
It is a detection system which refers to the detection of an attack by looking for the specific patterns, such as byte sequences in network traffic, or known malicious instruction sequences used by malware. This IDS originates from anti-virus software which can easily detect known attacks. In this terminology, it is impossible to detect new attacks, for which no pattern is available.
4. Anomaly-based Intrusion Detection System-
This detection system primarily introduced to detect unknown attacks due to the rapid development of malware. It alerts administrators against the potentially malicious activity. It monitors the network traffic and compares it against an established baseline. It determines what is considered to be normal for the network with concern to bandwidth, protocols, ports and other devices.
Access Control
Access control is a process of selecting restrictive access to a system. It is a concept in security to minimize the risk of unauthorized access to the business or organization. In this, users are granted access permission and certain privileges to a system and resources. Here, users must provide the credential to be granted access to a system. These credentials come in many forms such as password, keycard, the biometric reading, etc. Access control ensures security technology and access control policies to protect confidential information like customer data.
The access control can be categories into two types-
Physical access control
Logical access control
Physical Access Control- This type of access control limits access to buildings, rooms, campuses, and physical IT assets.
Logical access control- This type of access control limits connection to computer networks, system files, and data.
The more secure method for access control involves two - factor authentication. The first factor is that a user who desires access to a system must show credential and the second factor could be an access code, password, and a biometric reading.
The access control consists of two main components: authorization and authentication. Authentication is a process which verifies that someone claims to be granted access whereas an authorization provides that whether a user should be allowed to gain access to a system or denied it.
