Internal Network Security
Introduction
The development of technology has brought Internet to become the mass communication media between people or companies. Through Internet, people can communicate with other people in various places. Companies can get many advantages by using Internet network to support their business. Therefore, companies are trying as hard as they can, and give high effort in protecting their network from attack and make sure that they have the best network security.
Most people think that the threat of security attack is only come from outside the company. In fact, the attack from inside the company network is more harmful with high frequency to be happened. As written by Cryptek (2001), which based the argument from some articles, that threats from inside are far more dangerous than attacks from outside, and even FBI also stated that the average cost of an insider breach is $ 2.4 million while the average cost of a break-in from the Internet is $ 27,000.
All the facts above show that company must also think how to defend their network security from inside intruders, and not only concern about put firewall to protect their network security from outside. Companies must find way how to protect their information assets from attack, and make their network security is effective to block the threats either from outside or inside company.

The Importance of Internal Security
There are some reasons why inside intruders are as harmful and dangerous with outside intruder. It is because, for some organizations, especially big one, to support their company’ business, their facilitated their partners, customers, relations with the easiness technology can offer such as remote offices, mobile customers. All of the facilities boost up the use of corporate LAN increase, which resulted the increase of internal security threats, vulnerabilities to be attack by either outside or inside intruders.
As written in Cryptek (2001), there are some problems make the inside network

These passwords will be changed on a regular basis. Access to the local network will be secured by user authentication passwords. Users will be limited to only the system resources that they absolutely need to complete their work. Users’ passwords must be changed every 90 days.…

    Looking at the network diagram provided I determined that the user, workstation, LAN, LAN-to-WAN, and system/application domains involved in the company should be redesigned to implement better access controls to provide multi-layered security. The most important access control implementation would be the user domain where the company should put emphasis on training; how to recognize social engineering attacks, how to create strong passwords, and how often they should be changed. The workstation domain should focus security via virus and malware scanning, operating system patching, and other types of application-level firewalls. To achieve a multi-layered security approach in the LAN domain I would recommend using an intrusion detection system (IDS) and an intrusion prevention system (IPS) to prevent unauthorized access. Security for the LAN-to-WAN domain should be implemented through the use of a firewall or DMZ to also prevent unauthorized access into the company’s network.…

    Between every network and the outside host of threats there is a first line of defense. For almost every network this will be a firewall. A firewall can be both hardware and software and is usually a combination of the two. A firewall creates a barrier between networks. Any outside computer or client must pass through the firewall to access the network or its resources. Only a computer or system that has proper access can easily access a network protected by a properly configured firewall. Though it is not infallible, a firewall is the first and perhaps best means of security…

    Currently the security for the internet server and the location of it in the network is not as protected as it should be and it is not the best design either. The internet server must be located out of the company firewall to protect the systems and network internally. By doing this it separates the remote server system the system has proper validation and connection through the system allows access to the rest of the network. Staffs that are located in the firewall can authenticate through a proxy system and then access the internet, which in turn allows them to communicate…

    To secure the network and ensure a degree of protection from external intrusion, the first step is to ensure it is a private network and each host in the different remote locations is part of the private network; this minimizes the intrusion from public networks. Through the use of firewalls in the central computer network enforces authentication of all users in the network thus minimizing internal and external unauthorised access (Stallings, 2007).…

    In User Domain the people are often the weakest link in IT security. In Workstation Domain is vulnerable if not kept up to date. In LAN-to-WAN Domain IP addresses are accessible from anywhere in the world, and attackers are constantly probing public IP addresses. They look for vulnerabilities and when one is found, they pounce. In Remote Access Domain is vulnerable to authentication because when the user provides credentials to prove identity, if found the attacker can later use them to impersonate the user. Also when data is passes between the user and the server. In WAN Domain is the same vulnerabilities as LAN-to-WAN Domain. In System/Application should remove unneeded services and protocols, change default passwords, and regularly patch and update the server systems.…
