With the growth of the information and technology, the network security becomes even more important to secure the database from the unauthorized person. Nowadays more cybercrime using the data for information leaking, Identity Theft, and Cyberstalking. Fortunately, there are available or a way to measure the security control for the airport such as implement the firewall, antivirus, service auditing and Intrusion-detection systems.
Firewall
It important to setup the network firewall as a security measure which with help to defend any device or connection based on the set of rules configure by the system administrator. The firewall works as filtering and examine the information packet and determining the source before they forward to the destination for the data packet. There is two type of firewall which is hardware firewall and software firewall. The hardware firewall is network build into the device such as router help to filter the unsuspicious incoming connection from entering the server or the host computer based on the administered configuration which works effectively. The software firewall is are stand-alone software are install into the host computer act as anti-virus protection example BullGuard

They must present any loss of data and information to unauthorized user. The internal organization must review and analysis the IT security of the organization in term of IT security, infrastructure and internal control. For some organization can get a security consulting to conduct the certified the service audit where they review the OS/ platform layer, network/ server layer, and the application layer. They will run the security test for the vulnerability and giving the security overview as a result. There are few example of the service auditing they must review the scope such as network architecture, database server and Lan/internet
In order to protect the application servers from the internet, the most common un-trusted network, the proposal suggests a firewall to be installed between the internal network and external router. The firewall would be an Adaptive Security Appliance (ASA) firewall, "the ASA is not just a pure hardware firewall. In brief, the Cisco ASA is a security device that combines firewall, antivirus, intrusion prevention, and virtual private network (VPN) capabilities. It provides proactive

This is only a small part of the prevention of infiltration of your network and computer. If one desires to learn more, go above and beyond and continue to learn on how to keep your network secure.
The firewall is commonly the first line of defense in the layered security structure. Also known as a broader sentry. “The firewall protects the internal network from unauthorized access from the internet, but also has the ability to protect internet from rogue users or applicatio...
A hardware firewall is used most often when multiple devices on a network need to be protected by a firewall. Hardware firewalls are a necessity if you need to have a centralized point for protection and easy management of the firewall. You can purchase hardware firewalls as just a physical device or as part of broadband router that already has the firewall built into it. Hardware firewalls can be some-what effective with very little, and sometimes no, effort on the users part in terms of actually configuring the device. Most hardware firewalls come already set with predefined rules on what is ok to pass through onto the network and what is not ok to pass through onto the network. Almost any computer user can plug in a hardware firewall, adjust a few settings and be on their merry way. But being how this device is made to protect your computer(s), your network, and possibly your assets, it would behoove you to learn the specific features of the firewall, what it allows and what it doesn’t allow, and how to enable and disable those features. Once you know how everything works you should test your firewall for optimal security and protection. Firewalls are not all created equally so it is important that your read all documentation that came with the device and go over the manual to get a full understanding of what exactly you have gotten yourself into. Your hardware firewall should always sit on the outermost portion of your logical network. This is known as the perimeter of ...
One essential part of the airport system is security. Today, security is a major priority that airports must administer strictly. Due to the recent terrorist attacks on September 11, 2001, airports along with airlines want their customers to feel safe.
Lastly, the application layer (Layer 7) supplies services to application procedures and threats are static passwords and SNMP private community strings (Holl, 2003). Organization will need to enforce encryption to limit the exposure of personal information, ensure that patches are installed for applications, patching and is performed on all network and hardware devices, hardening of operation system and implements secure authentication methods (Baker & Wallace, 2007). Additionally, a quality anti-virus is utilized on workstations, servers and other devices connected to the organization IT infrastructure. All types of attackers discussed in this paper are applicable. Black hat hackers and cyber terriorist will control exploit vulnerabilities in networks and application systems that are not properly patch as well as malware writer
This paper has covered the many different aspects of airport security. It is important to keep in mind that procedures, regulations, and technology associated with airport security are in a state of constant change. However, it is through these changes that our nation’s airports will show a steady improvement towards the safety and security of the passengers that visit them.
A firewall is a network device, hardware, software, or a combination of the two, whose purpose is to enforce a security policy across its connections. It is comparable to a wall that has a window where the wall serves to keep things out, except those permitted through the window. A security policy acts like the glass in the window; it permits some things to pass, light, while blocking others, air. The heart of a firewall is the security policy that it enforces.
Airport security is critical because it has significant effects of the country’s economy. Design or modification should integrate security measures into airport planning. Such modifications are likely to affect the landside elements, terminal elements, as well as airside elements. The identification of potential vulnerabilities in the airport is instrumental in developing airport design modifications that aim at integrating security needs.
There are two main types of Firewalls one is Enterprise Firewall or Network Firewall and other is Host based Firewall. Two of these are generally used to secure the system by controlling the network traffic by allowing or denying them. Their primary function is to filter the traffic. Network Firewalls are used for protecting the perimeter of network Whereas Host based Firewall protects an individual computer regardless of the network it is connected to. The primary role of firewall is to enforce security policy.
Hardware and software are combined to get the firewall. The access control policies, enforces corporate security and others are the effective firewall that are been created on the markets. The firewall gives the benefits to any organization that use and has it in their systems. The benefits that they get are security and auditing. Firewall is being choosing by the organization because it has the high security that can save all the data and files. If the firewall is not being use by the organization, it can expose the system that created to the intruders like hackers and spies.
Not many people know or are aware of what a firewall is or how it works. Firewalls are installed onto your computer system as a security system that is making sure that nothing such as a virus gets into your computer, it also controls the incoming and outgoing network traffic based on how the person set the settings. Firewalls were first used in the 1980’s it was called a packet filter before actually called a firewall. Firewalls are meant to be installed on your computer so that your computer won’t be hacked. A firewall is the most common security system used in any type of computer. Many people think that a firewall is something simple that once it is installed and applied, then it will work perfectly fine, but in reality a firewall should
This paper describes the basic threats to the network security and the basic issues of interest for designing a secure network. it describes the important aspects of network security. A secure network is one which is free of unauthorized entries and hackers
The packet-filtering firewall will keep out unauthorized data from entering the network and reduce the number of ports that are accessible by the users and outside threats.
