Series Stackable Manage Switched Data Sheet â€Myassignmenthelp.Com

Question: Discuss About The Series Stackable Manage Switched Data Sheet? Answer: Introducation Main scope of this project is to create the secure network design for B2B solutions. The B2B solutions is medium sized organization. It interests to create the secure network design. The B2B solutions has the six building such as finance office, Information technology office, research office, sales office, transport office and head office. Each office contains the workstations. The Finance offices has the 50 work stations, sales office has the 25 work stations, transport office has the 50 workstations, head office has 50 work stations and information technology office has the 250 workstations. These buildings are connected with the routers and each building has the single subnet. The proposed network design for B2B solutions is provides the productivity and security of the network. It uses the cisco products to reduce the maintenance and operational costs. The Network security threats will be analysed. The network design hardware and software components are will be addressed. The pro posed network design will be ensuring the confidentiality, integrity, availability and Authorization of the network. Security Threats The Network security threats are classified into two types such as passive threats and active threats. The Network security threats diagram is shown in below [1]. The passive threats re referred to as eavesdropping dropping and it involves the attempted by an attacker to obtain the information relating to communication by using the traffic analysis and release of message content method. The Release of message contents are used to transferred the file may contain the confidential and sensitive information. It prevents the opponent from data or message transmission. The traffic analysis is a kind of attack done on encrypted messages. The active threats are involving the data stream modification and false stream creation by using the masquerade, replay, message modification and denial of service techniques. The Denial of services attack takes place when the network availability to a resource is blocked by an attacker. It disruption of an entire network by disabling the network [2]. The proposed network design provides the secure network by using the firewalls. The firewalls provide the security and productivity of the network. The Firewalls is us ed to blocking the unauthorised access to prevent the sensitive informations. Software Requirement The Network design software requirements are shown in below. Operating system windows Memory 2 GB RAM Hard Drive 2.2 GB Hardware Requirement The Hardware requirements are shown in below [3]. Cisco Routers Cisco 800 Series Routers Cisco Switches Cisco Small Business 500 Series Switch Cisco Access Point Cisco 300 Series Access Points Cisco Firewall Cisco ASA 5506-X with Fire POWER Services Cisco Core switch Cisco Nexus 7000 Series Switches Requirement Specification Specification of network devices is shown in below. Cisco Routers cisco 800 Series routers It uses maximum power consumption is 11w to 18 w. It does not have the extended shock-vibe It has operating temperature and altitude is 0 to 40-degree Celsius. It has maximum 85% of humidity [4]. Cisco Switches - Cisco Small Business 500 Series Switch It supports he standard 802.1d spanning tree protocol. In VLAN, it supports the 4096 Vlan simultaneously port based. In Voice VLAN, the voice traffics are automatically assigned to a voice specific VLAN. IT blocking Head of Line It supports the classless Inter domain routing Cisco Access Point - Cisco 300 Series Access Points It enhanced the mobile guest experience. It provides the strong security [5]. Easy to set up the peer-peer video conferencing for collaboration It easily enables the next generation connected digital classrooms. It minimizing the total cost of ownership for the network. Cisco Firewall - Cisco ASA 5506-X with Fire POWER Services It provides the ASA firewall functionality, advanced breach detection and advanced threat protection. Highly secure and reliable access High performance It uses advanced malware protection like blocking, detection, analysis, remediation and tracking to protect the enterprises [6]. It reduces operation costs. It provides the administrative visibility. Cisco Core Switch - Cisco Nexus 7000 Series Switches It combines the high levels of scalability with operational flexibility. It provides the integrated resilience combined with features. It also provides the reliability and availability of the network. High Performance. It helps to ensure the system reliability [7]. Network Design The B2B solution network infrastructure is shown in below. The B2B solutions network infrastructure consists of six building such as Finance office, sales office, head office, information office, research office and transport office. The Six building totally contains the 500 work stations. These are connected with the routers. The router connecting the core switch to connect the six building through cisco switches. The cisco products are providing the secure and scalability of the network for B2B solutions. The Proposed network design is used to provide the secure communication between the employees and organization team. It maintains network availability and usability [8]. The Proposed network design has the flexibility and availability of the network to delivers the secure network for entire organizations. The secure network design is decrease the operational and maintenance costs. Because the proposed network design does not require the maintenance costs to maintain the network. The cisco products are reduced the operational costs. The si x building are securely communicated with each others [9] Justification for CIAA The network design ensures the confidentiality, integrity, availability and authorization by using the cryptographic algorithms. the cryptography plays a major role in network security. The network security goals are based on confidentiality, integrity, availability and authorization. these are designed to act as guide for information security policies [10]. Confidentiality The confidentiality is protecting the information from the disclosure to unauthorised users. The confidentially protecting the information by encrypting the information. the encryption ensures the only the right peoples can be read the information. It provides the security for the sensitive information [11]. Integrity The integrity is used to protecting the information from being modified by unauthorized users. the cryptography plays a major role in ensuring the data integrity. The to protect the integrity by using the various methods includes hashing the data and comparing the hash messages. The availability is used to protect and ensures the information that authorised users are able to access the information when needed. It does not allow the unauthorised users accessing the information. It denying the access to information has become a very common attack. To ensure the data availability by backup the informations. It provides the security and productivity. It reduces the down time [12]. Authorization The authorization is used to allow an authorised users only accessing the information. The cryptography algorithms also provide the authorization of the users. It first authenticates the users, after provides the accessing permission. The Cryptography authorization is used to provide the security from attackers. Conclusion B2B solutions current network does not have the security. The B2B organization team interested to create the secure network design. The network design has the six building such as finance office, transport office, research office, sales office, head office and information technology office. Overall B2B network infrastructure has the 500 workstations. These building are connected with the routers. The router connecting each building by using the core switch. The six buildings are communicated with each other. The proposed network design provides the secure network design by using firewalls. The firewall is used to provides the productivity and security for the network. It blocking the unauthorised users. The network security threats are identified and discussed. The hardware and software requirements are identified and discussed in detail. The Justification of confidentiality, availability, integrity and authorization is done by using the cryptographic algorithms. References [1]J. Kurose and K. Ross,Computer networking. .
