Cisco Certification Exams And Successful CaseThree-dimensional defense of subnet 200-125 exam dumps segment: the head office data center deploys double redundant PIX535 fire wall, divides the Practice Test head office network into multiple isolation network segments: internal functional network, external network, INTERNET, etc.The isolation of firewall prevents security problems such as cross-network attack and internetwork interference. Practice Test Meanwhile, the scope of virus infection can also be 200-125 exam dumps 300-101 Questions and Answers effectively controlled, which greatly Practice Test improves the security of each 200-125 exam dumps network segment.The core switch of Practice Test the business network USES two Catalyst6500 200-125 exam dumps high-performance switches with IDS module to enhance security monitoring of the business network through IDS module.OA network 200-125 exam dumps is a key part of security and a major part of internal security risks. Therefore, OA network USES two Catalyst6500 high-performance switches with IDS and Firewall modules.The Firewall module enables Practice Test security isolation between virtual lans, which is important for large OA networks.Guangdong development bank network system, including Practice Test the head 200-125 exam dumps office data center and branch network, all need with the Internet, online banking, a shekel of silver coupon, and pedestrian liquidation, and other public information network interconnection, because these public information network is a completely open 200-125 exam dumps to the public information resources, so the network interface as the most vulnerable to hacking and require special safety control, provide reliable security.Therefore, Cisco has adopted the current advanced Cisco PIX firewall products and advanced and reliable firewall technology to provide reliable Practice Test security protection for the entire network system.PIX of NAT (Network 200-125 exam dumps Address Translation) function for guangdong development bank Intranet Address Translation of each workstation provide dynamic or 300-101 Questions and Answers static gain legal external Address, such 200-125 exam dumps as well as 300-101 Questions and Answers to hide the internal Network, and can save the Address resource.In order to improve network reliability and eliminate single point of failure, cisco took measures to connect two PIX firewalls with a Failover cable to perform a two-machine thermal backup.Firewall Practice Test as the only export bank internal network, with the Internet and other public information network interconnection security control, 300-101 Questions and Answers at the same time for each workstation to access external information network within the network address translation (NAT) function.The switch USES MAC address filtering for security control, allowing only specific hosts to enter the PIX.The router is connected through multiple wan ports and provides certain security control to prevent illegal access 300-101 Questions and Answers and operation.In order to strengthen the control and management of the 300-101 Questions and Answers whole network, deployment of 300-101 Questions and Answers the ACS and Cisco for guangdong development bank access control server and security Policy Manager (Cisco Secure Policy Manager), using CSPM powerful strategy management infrastructure, users can bank on the network security products for scalable, unified management.

Hierarchical integrated defense: cisco SAFE Practice Test that successful security solution should adopt integrated 300-101 Questions and Answers protection on the network infrastructure, and not only consider some special safety equipment.As a result, cisco has integrated security capabilities into its various network products to ensure that the entire network is fully integrated and three-dimensional.Guangdong development bank has implemented such a three-dimensional integrated security defense.Take the guangdong development bank’s outreach network system, for example, which USES three layers of integrated security protection, including routers, firewalls and switches.1, the first layer security protection provided by the router to achieve router in Internet/extranet wan connection of public information network, such as DNS server with guangdong development bank, Practice Test the WWW server and E-mail servers located in external PIX firewall, with these servers as part of the opening to the outside world, the ministry of internal and Practice Test external users to provide the corresponding services, its itself also become a part of the public information network.These Practice Test servers in 300-101 Questions and Answers order to provide 200-125 exam dumps effective security, prevent the 200-125 exam dumps outside of the user to the illegal operation of the server, the server, delete, modify, or the content, should be carried out to external access can strictly control.With the firewall function of Cisco router, the operation of external users on the servers can be restricted to prevent the servers from being damaged from the outside.2. The second layer of security protection is protected by PIX firewall, which completely separates 300-101 Questions and Answers the internal network of enterprises from the external network. 300-101 Questions and Answers PIX is the 200-125 exam dumps only outlet for the internal network subsystems.By using PIX firewall to isolate the internal and external network, the security of Practice Test the internal network is further guaranteed.PIX provides a complete record of all access, including illegal intrusion attempts.PIX realized from the network layer to application layer security protection, 200-125 exam dumps can Practice Test be based on packet source address, destination address, TCP port Numbers and packet length on 200-125 exam dumps the communication control, as Practice Test a move method to access is prohibited.3, the third layer 300-101 Questions and Answers security protection provided 300-101 Questions and Answers by the LAN switches Catalyst 6500 core switches deployed IDS and firewall module, monitoring the safety of the complex intranets effectively, is the third barrier against external attacks to prevent, is a good method to prevent internal attacks.Another Catalyst series switches have MAC address filtering function, therefore can be defined according to the need to switch each port, only allow specific MAC address of the workstation through 300-101 Questions and Answers the specific port access, port to communicate with the connection PIX.Due to the uniqueness of the MAC address and not configured, this kind of control, in fact, from hardware to control a specific machine, compared with the 300-101 Questions and Answers IP address filtering, this protection has higher security.Through the above three layers of security protection, guangdong development bank network system to realize the reliable from 200-125 exam dumps link layer to Practice Test application layer security control, have the effect to prevent illegal access external, has the very high security.Reading this wasn’t the first time I’ve paused to consider whether my heart’s and my people’s infatuation with autumn 200-125 exam dumps is not a worldly indulgence. The promise of the Kingdom is fullness of life, not pretty death.
