Hierarchical integrated defense: cisco SAFE that successful security solution should adopt integrated protection on the network infrastructure, and not only consider some special safety equipment.As 210-260 exam a result, cisco has integrated security 200-310 exam capabilities into its various network products to ensure that the entire Exam dumps network is 200-310 exam fully integrated and three-dimensional.Guangdong Exam dumps development bank has implemented such a three-dimensional integrated security defense.Take the guangdong development 200-310 exam bank’s outreach network system, for example, which USES three layers of integrated security protection, including routers, firewalls and switches.1, the first 210-260 exam layer security protection provided by the router to achieve router in Internet/extranet 200-310 exam wan connection of public information network, such as DNS server 200-310 exam with guangdong 210-260 exam development bank, the WWW server and 210-260 exam 210-260 exam E-mail 200-310 exam 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 corresponding services, its itself also become a part of the public information network.These servers in order to provide 200-310 exam 210-260 exam effective security, prevent Exam dumps the outside of the user to 200-310 exam 200-310 exam the illegal operation of the server, the 210-260 exam server, delete, modify, or the content, should be carried out to external access can strictly control.With the firewall function of Cisco Exam dumps router, the operation 200-310 exam of external users on the 200-310 exam servers can be restricted Exam dumps to prevent the servers from being damaged from the outside.2. The second layer of security protection is protected by PIX Exam dumps firewall, which completely 200-310 exam separates the internal network of enterprises from the external network. PIX is the only outlet for 210-260 exam the internal network subsystems.By using PIX firewall to isolate the internal and external network, the 210-260 exam security of the internal network is further guaranteed.PIX provides a complete record of all access, including illegal intrusion attempts.PIX Exam dumps realized from the network Exam dumps layer to application layer security protection, can be based on 200-310 exam packet source address, destination address, TCP port Numbers and packet length on the communication control, as a move method to access 210-260 exam 210-260 exam is prohibited.3, the third layer security protection provided by the Exam dumps LAN switches Exam dumps 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 210-260 exam Exam dumps through the specific port access, port to communicate with 210-260 exam the connection Exam dumps PIX.Due to the uniqueness of the MAC address and not configured, this kind of control, in fact, from hardware to control a 200-310 exam specific machine, compared with the IP address filtering, this protection has Exam dumps higher security.Through the above three layers of security protection, guangdong development Exam dumps bank network system to realize the reliable from link layer to application layer security control, have the effect to prevent illegal access external, has the very 200-310 exam high security.Reading this wasn’t the first time I’ve paused to consider whether my heart’s and my people’s 210-260 exam infatuation with autumn is not a worldly indulgence. Exam dumps The promise of the Kingdom is fullness of life, not pretty death. Halloween just means Exam dumps “the night before the Saints” and all the gruesomeness on display represents the demons coming out one last night 200-310 exam before the Saints arrive and drive them all away. A Christian may secretly treasure the festival for that reason, but how can she join in when her place is not with the demons 210-260 exam and decay, 210-260 exam but with the Saints and salvation? Whence this covert delight in the season’s celebration of fear and death?
