IP phone in the office in 2002, the deployment of workplace sharing becomes more convenient, because it gives employees can use the Cisco CallManager mobile extension function, easily in any work area set any a phone to your own personal extension. Through the cisco wireless LAN technology, employees can freely Shared from offices in any location, including desk and access the company network, conference room, which can be in the office any space into an efficient workplace. In this case, all the measure make Cisco's Sao Paulo office has evolved from a traditional environment of fixed offices and cubicles to an almost entirely virtualized workplace.Using the Internet solutions, cisco greatly reduces the space requirements of office, and in three years time saved $1.2 million in profit and loss cost, and a $1 million spending (cash flow).That translates to a 30 per cent reduction in the cost per employee per year - from $8,483 per person per year to $5,671 per person per year. The office's productivity has also improved.One survey found that staff at the Sao Paulo office saw their productivity increase by an average of 9% in the new working environment (more on this below).In addition, because this kind of environment, technology environment and office management encourages employees to move office, so employees can work from home in the rush hour, so that each employee can save on average every week 4 hours of traffic jam.
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 of the business network through 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 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 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 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 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 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 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 and operation.In order to strengthen the control and management of the whole network, deployment of 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.
