You are in charge of the security of information in a research lab. Most of the information is stored in electronic format on the LAN. The researchers can also access these files from their homes. The computers in the lab are also connected to the Internet. The current access is provided to Internet via a combination router-firewall. The entire network resides behind this single firewall-router configuration. It is quite important to maintain the confidentiality of the information, although the lab has limited funds allocated for security. There are 8 workers that use the network connections.

Individual users play an important role in any form of institution or organization but concerns are raised about the security. The network administrators clearly lay down a set of rules, regulations and protocols that an individual user has to agree accordingly upon which part of the resources and what class of service that the user can obtain.

The firewall providing the DMZ segmentation should allow only inbound packets destined to the corresponding service ports and hosts offering the services within the DMZ. Also, limit outbound initiated traffic to the Internet to those machines requiring access to the Internet to carry out the service they are

The best network design to ensure the security of Corporation Techs internal access while retaining public Web site availability consists of several layers of defense in order to protect the corporation’s data and provide accessibility to employees and the public.

You are filtering MAC addresses on a switch by blocking only specific IP addresses. What do you use to perform this type of filtering?

The public facing servers used to connect the internal webserver to the customer website are contained within the demilitarized zone. Due to the demilitarized zones proximity to the wide area network, we will be taking a layered security approach. There will be a statefull firewall located between the router and the demilitarized zone. This firewall will protect the internal network via the LAN-to-WAN connection by performing in-depth packet inspection and closely

Oracle designs, develops, and supports computer-software products. This software is used for database management and network products, application development productivity tools, and end user applications. The company’s principal product, the oracle relational database-management system, runs on supercomputers, mainframes, microcomputers, and personal computers. The company also offers consulting, support, and system integration services for its customers. Oracle Corporation provides the software that powers the Internet.

As the use of computers, databases, and technology in general, security has grown to be a powerful tool that has to be used. The threat of outside sources intruding and exploiting crucial information is a threat that is present on a daily basis. As a part of creating and implementing a security policy, a user must consider access control. Access Control is a security tool that is used to control who can use or gain access to the protected technology. Access control security includes two levels; logical and physical. Though database intrusions can happen at any moment, access control provides another security barrier that is needed.
