The Seven Domains of IT Infrastructure

Extracts from this document...

Introduction

Seven Domains of IT Infrastructure Seven domains can be found in a typical IT infrastructure. They are as follows: User Domain, Workstation Domain, LAN Domain, LAN-to-WAN Domain, Remote Access Domain, WAN Domain, and System/Application Domain. Each of these domains is viewed as portals for attackers if countermeasures are missing or fail. It is very imperative for businesses to protect each of these seven domains. It only takes one unprotected domain for an attacker to gain access to private data. The User Domain is comprised of individuals that are often not aware of the tricks of attackers. For example, networks usually have strong passwords that one must know in order to gain access to the Internet. Nevertheless, social engineers can persuade individuals to give out personal information such as passwords and other types of private information. ...read more.

Not only can malware affect a single computer but also can infect the whole network. If a computer does have an antivirus program, it must keep its definitions updated simply because new malware can come into existence. By having an antivirus program that is regularly updated can greatly decrease the likelihood of the workstation becoming infected with malware. Inside the firewall is an area known as the LAN Domain. The LAN Domain can either consist of many computers connected together or a few computers connected together. If measures aren't taken to protect the LAN Domain, attackers will easily gain access to the system. The computer systems are all connected by hubs, switches, and routers. Computer systems connected by hubs contribute to sniffing attacks. ...read more.

Conclusion

If the data is left unprotected, attackers will have the potential to attack the system. The WAN instead of the LAN is used as the Internet for most businesses. Given this condition, it is very important for businesses to maintain security on all systems for two reasons. First, the WAN is an untrusted zone. Second, the Internet is also an untrusted zone that is composed of hackers. Therefore, it is highly recommended that businesses keep all systems heavily secured in order to prevent attackers from gaining access. Last but not least, the System/Application Domain consists of servers that must be protected. Several steps must be taken to keep attackers from gaining access to the System/Application Domain. First, all services and protocols that are not used should be removed. Second, new passwords should be formed. Third, the server system should be updated. Last, all firewalls should be turned on. ...read more.
