Catalyst 6500 core switches deployed IDS and firewall module, monitoring the safety

We are the only one Practice Test site can offer demo for almost all products. Cisco Certification 300-101 Practice Test Exams And Successful CaseThree-dimensional defense of subnet segment: the head 300-101 Practice Test office data center deploys double redundant PIX535 fire wall, divides the head office network into multiple isolation network segments: internal functional network, external Practice Test 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 200-310 pdf network USES two Catalyst6500 high-performance switches with IDS module to 300-101 Practice Test enhance security monitoring of the business network through 300-115 pdf IDS module.OA network 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 security isolation between virtual lans, which is important for 300-101 Practice Test large OA networks.Guangdong Practice Test 200-310 pdf development bank network system, including the head office Practice Test data center and branch network, all need with the Internet, online banking, a 300-101 Practice Test shekel of silver coupon, and pedestrian liquidation, and other public 300-115 pdf information network interconnection, because these public information network is a 300-115 pdf completely open to the public information resources, so the network interface Practice Test Practice Test as the Practice Test most vulnerable to hacking and require special safety control, provide reliable security.Therefore, Cisco has adopted the current advanced Cisco PIX firewall products 300-115 pdf 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 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 300-115 pdf 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 as the only export bank internal network, with the Internet and other public information network 300-101 Practice Test interconnection security 300-101 Practice Test control, at 300-101 Practice Test 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 200-310 pdf control, allowing 200-310 pdf only specific hosts to enter the PIX.The router is connected through multiple wan ports and 300-115 pdf provides certain security control to prevent illegal access and operation.In order to strengthen the control and management of the whole network, deployment of the ACS and Cisco for guangdong development Practice Test 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 that successful security solution should adopt integrated protection on the network infrastructure, 200-310 pdf and not only consider some special safety equipment.As a Practice Test result, 200-310 pdf cisco has integrated security capabilities into its various network products to ensure 300-101 Practice Test that the entire network 300-115 pdf 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 300-101 Practice Test 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 200-310 pdf of public information network, such as DNS server with guangdong development bank, the 200-310 pdf 200-310 pdf WWW server and E-mail servers 300-101 Practice Test located in external PIX firewall, with 200-310 pdf these servers as part of the opening to the outside world, the ministry of internal and external users to provide the corresponding services, its itself also become a Practice Test part of the public information network.These servers in order to provide effective security, prevent the outside of the user to 200-310 pdf 300-115 pdf the illegal operation of the server, the server, delete, modify, or the content, should be carried out to external access can Practice Test strictly Practice Test control.With 300-115 pdf the firewall function of Cisco router, the operation of external users on the servers can be restricted to prevent the 200-310 pdf servers from being damaged from the outside.2. The second layer of security protection is protected by PIX firewall, which completely separates the 300-115 pdf internal Practice Test network of enterprises from the external network. PIX is the only outlet for the internal network subsystems.By using PIX firewall to isolate the internal and external network, the security Practice Test of the internal network is further guaranteed.PIX provides a complete record of 300-115 pdf all access, including illegal intrusion attempts.PIX realized from the network layer to application layer security protection, 300-115 pdf can be based on packet source address, destination address, TCP 300-115 pdf port Numbers and packet length on the communication control, 300-101 Practice Test as a move method to access is prohibited.3, the third layer security protection provided 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 200-310 pdf to switch each port, only allow 300-115 pdf specific MAC address of the workstation through the specific port access, port to communicate with the 300-101 Practice Test 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 IP address filtering, this protection has higher security.Through the above three layers of security protection, 300-115 pdf guangdong development bank network system to realize the 300-115 pdf reliable from link layer to application layer security control, have the effect to prevent illegal access external, has the very high security.Reading this wasn't the first 300-101 Practice Test time I've paused to consider whether my heart's and my people's infatuation with autumn is 200-310 pdf not a worldly indulgence. The promise of the Kingdom is fullness of life, not pretty Practice Test death. Halloween just means "the night before the Saints" and all the gruesomeness on display 300-101 Practice Test represents the demons coming out one last night before the Saints arrive and drive them all away. A Practice Test Christian 200-310 pdf may secretly treasure the festival for 200-310 pdf that reason, but how can she join in when 300-101 Practice Test her place is not with the demons and decay, but with the Saints and salvation? Whence this covert delight in the season's celebration of fear and death?
