Designed And Description Design Evaluated

 

The Scope of this project is to create the secure network design for B2B solutions. The B2B solutions expanding their operations. So, organization team decided to creating the network design. The B2B solutions has the six building and various departments. It Each building the has the separate work stations. The Six buildings are finance office, sales office, research office, transport office, Information technology office and head office. the finance office contains the 100 work stations, sales office contains the 25 workstations, research office contains the 25 work stations, transport office contains the 50 work stations, head office contains the 50 work stations and information technology office contains the 250 work stations. Each building has the single subnet. These are connected with each other by using the routers. The Proposed network design provides the security and productivity of the network infrastructure for B2B solutions. The Network security threats are will be identified. The proposed network infrastructure hardware and software components are will be addressed and discussed in detail. The justification of proposed network design will be justified by ensuring the confidentiality, integrity, availability and authorization model in the network.

Network Security Threats

The security threats are divided into two categories like active and passive threats. The passive threats are identified to as eavesdropping and it involves the attempted by hackers to obtain the information related to communication [1]. It obtained by using the release of message content and traffic analysis method. The release of message content is used to identified the transmitted the file may contain sensitive and confidential information. So, it prevents the opponent from the message or data transmissions. Another method is traffic analysis. It is a kind of attack done on encrypted messages. The Active threats is including the false stream creation and data stream modification by using the denial of service and message modification method. The denial of services is one of the attack and it take the place when the network availability to a resource is blocked by a hacker. The proposed network design is used to provides the secure network by using the cisco firewalls. The firewalls are used to blocking the unauthorised access to prevent the sensitive information’s.

The proposed network infrastructure for B2B solutions is shown in below.

The B2B solutions proposed network infrastructure is used to provide the security and productivity of the network [8]. It has the six building for various department. These are finance office, transport office, sales office, head office, research office and information technology offices. These are connected with each other by using the router. The router is connecting the six building by using the core switches and switches. The Each building has the single subnet. Each building is communicated with others. The Proposed network design uses the cisco network devices like cisco routers, switches, access point, core switches, server and cisco server. It provides the secure wireless network connection for each building by using the cisco access point. It cisco network devices are used to reduce the operational and maintenance costs [9].

Justification

The Proposed network solutions is used to ensures the confidentiality, availability, integrity and authorization of the network [10]. The CIAA model provides the secure and effective network for B2B solutions by using the cryptographic algorithms. The Cryptography is plays a major role in network security. The CIAA models is one of the network security techniques. The proposed network solutions ensure the CIAA model by using the cryptographic algorithms. Justification of CIAA model is shown in below.

Confidentiality

It is used to prevent the sensitive information from unauthorized users. It only allows the authorised users to accessing the sensitive information. It provides the high data security. It encrypting the information to protect the sensitive information by using the SSL/TLS security protocol for communications over the network.  It ensures the information confidentiality include enforcing the file access control and permission to restrict access to information’s [11].

Integrity

The integrity is used to maintains the data consistency, trustworthiness and accuracy through the network. It ensures that data cannot be modified by unauthorised users. It measures the file permissions and access control lists. It verifies the data integrity by using the checksums and cryptographic checksums.

Availability

The availability is used to ensure the authorised users are able to access the information when needed. It provides the sensitive information for authorised users at the right times. It denying the unauthorised users are accessing the information. It ensures the data availability by using the cryptographic algorithms [12].

Authorization

The authorization is used to authenticate the users to accessing the sensitive information. It allows the authenticated users only accessing the campus information through the network. The Cryptographic algorithms provide the users authentications to accessing the information. The cryptographic mechanisms are used to provide secure network and effective network. The CIAA model is used to maintains the organization security and provide the scalable and reliable network.

Conclusion

The B2B solutions decided to create the secure network design because the organization expanding their operations. The B2b solutions consists of six building and various departments.
