Multi-Layered Security Plan Essay

Protecting sensitive or confidential info is paramount in umteen businesses. In the event such information is made public, businesses may face legal or fiscal ramifications. At the very least, they will suffer a loss of customer trust. In most cases, however, they substructure recover from these financial and other losses with appropriate investment or compensationHaving information of unlike security levels on the same computer systems poses a real threat. It is not a straight-forward matter to seclude contrastive information security levels, even though different users log in using different accounts, with different permissions and different access controls (Red Hat, Inc. 2006).Below I have listed the IT infrastructure of Richman Investments along with recommendations in individually infrastructure on levels of security that should be implemented for a more secure network.IT Infrastructure change1. User expanse The people who access an administrations information system.* The first thing that should be implemented is a mandatory Computer Security training session to educate the users on the graceful use of work computers.2. Workstation Domain Users (most) connecting to the IT infrastructure.* The workstation domain comes with its own problems such as unauthorized access to the system, the steering to fix this problem would be to implement access policies and guidelines.3. LAN Domain A collection of computers attached to one another or to a common connection medium.* Implement second or ternary level identity check to gain access to sensitive systems, applications, and date. Keep all hardware in a secure location with access only with proper ID.4. LAN-to-WAN Domain Link between the grand Area Network (WAN) and the Internet.* Conduct post configuration penetration tests of the layered security solution inwardly the LAN-to-WAN Domain. Test inbound and outbound traffic and fix any gaps. Also, apply e-mail server and attachments antivirus and e-mail quarantining for unknown file types. Stop domain-name Web site access based on content-filtering policies.5. WAN Domain Wide Area Network (WAN) connects remote locations to the Local Area Network (LAN).* Encrypt confidential data transmissions through service provider WAN using VPN tunnels.6. Remote Access Domain Connects remote users to the organizations IT infrastructure.* Remote Access Domain, Being that the users are off site it is hard to say that the users cry information has not been compromised. In such cases when abnormalities are spotted or data is accessed without proper authorization, data should be completely encrypted to prevent any sensitive materials from being sold or presented to the open market.7. ashes/Application Domain- Holds all the mission-critical systems, applications, and data.* Develop a business continuity plan for mission-critical applications providing tactical steps for maintaining availableness of operations. Perform regular rigorous software and Web-application testing and penetration testing prior to launch.
