Three-dimensional defense of subnet segment: the head office data center deploys double redundant PIX535 fire wall, divides the 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. Meanwhile, the scope of virus infection can also be effectively controlled, which greatly improves the security of each network segment.The core switch of the business network USES two Catalyst6500 high-performance switches with IDS module to enhance security monitoring 210-065 Exam details of the business network 210-065 Exam details 100-105 test downloadthrough IDS 100-105 test module.OA network is a key part of security and a major part of internal security risks. Therefore, 400-101 exam OA network USES two Catalyst6500 high-performance switches with IDS and Firewall modules.The Firewall module enables security isolation between virtual lans, which is 210-065 Exam details 100-105 test important for large OA networks.Guangdong development bank network system, including the head 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 to the public information resources, so the network interface as the most vulnerable 400-101 exam to hacking and require special safety control, provide reliable security.Therefore, Cisco has 100-105 test adopted the current advanced Cisco PIX firewall products and advanced and reliable firewall technology to provide reliable security protection for the entire network system.PIX of NAT (Network Address Translation) function for guangdong development bank 100-105 test Intranet Address Translation of each workstation provide dynamic or static gain legal external Address, such as well as 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 210-065 Exam details two PIX firewalls with a Failover cable to perform a two-machine thermal backup.Firewall as the only export bank 210-065 Exam details internal network, with the Internet and other public information network interconnection security control, at the same time for each workstation to access external information network within the network address translation (NAT) function.The switch USES MAC address 400-101 exam filtering for security control, 100-105 test 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 and 400-101 exam operation.In order to strengthen the control and management of the whole network, deployment of the ACS and Cisco for 400-101 exam 100-105 test guangdong development bank access control server and security Policy Manager (Cisco Secure Policy Manager), using CSPM powerful strategy management infrastructure, users 400-101 exam can bank on the network security products for 100-105 test scalable, unified management.
Hierarchical integrated defense: cisco SAFE that successful 210-065 Exam details security solution 400-101 exam should adopt integrated protection on the 400-101 exam network infrastructure, and not only consider some special safety 400-101 exam 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 100-105 test Internet/extranet wan connection of public information network, such as DNS server with guangdong development bank, 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 external users to provide the 100-105 test corresponding services, its itself also become a part of the 100-105 test public information 400-101 exam network.These servers in order to provide effective security, prevent the 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 damaged210-065 Exam detailsfrom the outside.2. The second layer of security protection is protected by PIX firewall, 400-101 exam which completely separates the internal network of enterprises from the external network. PIX is the only outlet for the internal network 400-101 exam subsystems.By using PIX firewall to isolate the internal and external network, the security of 100-105 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, can be based on packet source address, destination address, TCP 210-065 Exam details port Numbers and packet length on the communication control, as a move method to access is prohibited.3, the third layer security protection provided by the 400-101 exam LAN switches Catalyst 6500 core switches deployed IDS and firewall 210-065 Exam details 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 100-105 test series switches have MAC address filtering 100-105 test function, therefore can be defined according 400-101 exam to the need to 210-065 Exam details switch each port, only allow specific MAC address of the workstation through the specific port access, 210-065 Exam details 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 400-101 exam with the IP address filtering, this protection has higher security.Through the above three layers of security 400-101 exam 210-065 Exam details protection, guangdong development 210-065 Exam details bank network system to realize the 100-105 test reliable from link layer to application layer security control, have the effect to prevent illegal access external, has the very high security.Reading this wasnt the first time I’ve paused to consider whether my hearts and my peoples infatuation with autumn is not a worldly indulgence. The promise of the Kingdom is fullness of life, not pretty death. Halloween just means the night before the Saints and all the gruesomeness on display represents the demons coming out one last night 100-105 test before the Saints arrive 210-065 Exam details and drive them all away. A Christian 210-065 Exam details may secretly treasure the festival for that reason, but how can she join in when her place 210-065 Exam details is not with the demons and decay, but with the Saints and salvation? Whence this covert delight in the seasons celebration of fear and death?
