Comprehensive Understanding of Cisco Series Router Security Configuration

Cisco SDM is a good tool for vro security configuration. It features easy to learn and allows users to easily complete vro settings. Cisco SDM is based on Cisco IOS®An intuitive Web device management tool developed by Software routers.

It simplifies router security configurations through smart wizard, allowing customers and Cisco partners to quickly and easily deploy configurations and monitor Cisco systems without having to know the command line interface (CLI ).®Vro. Many Cisco routers and Cisco IOS Software versions support Cisco SDM. The model supported by Cisco SDM.

Ease of use and built-in Application Intelligence

With Cisco SDM, users can not only easily configure routing, switching, security, and Quality of Service (QoS) services on Cisco routers, but also perform active management through performance monitoring. Now Cisco SDM users can remotely configure and monitor Cisco routers without using the Cisco IOS Software CLI. The Cisco sdm gui can help non-expert users of Cisco IOS Software complete routine operations, provide easy-to-use smart wizard, automatically perform router security management, and provide users with comprehensive online help and guidance.

The Cisco SDM smart wizard guides you through systematic configuration of LAN, WLAN and WAN interfaces, firewalls, intrusion prevention systems (IPS), and IP Securtiy (IPSec) VPN to gradually complete the router and router security configuration. The Cisco SDM smart wizard can intelligently detect error configurations and propose repair suggestions. For example, if the WAN interface is specified by DHCP, Dynamic Host Configuration Protocol (DHCP) traffic is allowed to pass the firewall. In addition to detailed steps to help users enter correct data in Cisco SDM, online help embedded in Cisco SDM also provides the corresponding background information. Network and security terms and definitions that users may encounter are included in the online vocabulary.

For network experts familiar with Cisco IOS Software and its security features, Cisco SDM provides advanced configuration tools that can quickly configure and precisely adjust the security features of routers, this allows network experts to review commands generated by Cisco SDM before providing a router configuration change solution. Cisco SDM helps administrators use the Secure Sockets Layer (SSL) and vro security configuration (SSHv2) Protocols to connect to the remote location to configure and monitor vro1 Fig 1 ). Using this technology, you can establish a secure connection between your browser and vro over the Internet. When deploying a branch office, you can configure and monitor the Cisco SDM Router from the company headquarters, thus reducing the requirements of the branch office for senior network administrators.

Integrated Router Security Configuration

When deploying a new router, you can use the best practices recommended by the International Computer Security Association (ICSA) and Cisco Technical Support Center (TAC) to quickly configure the Cisco IOS Software firewall using Cisco SDM. Advanced firewall wizard allows one-step deployment of high, medium, and low application firewall settings. Cisco SDM users can configure the strongest VPN default values and automatically perform security audits. In addition, Cisco SDM users can perform step-by-step firewall locking and quickly deploy secure site-to-site connections through step-by-step VPN. The IPS signature table bundled with Cisco SDM recommended by Cisco can quickly deploy worm, virus, and protocol attack defense systems. The Cisco SDM network access control (NAC) wizard allows you to easily and quickly integrate NAC and Client Security Status management into your existing network infrastructure.

When calling a vro that has been configured, Cisco SDM users only need to perform one-step security audit to evaluate the advantages and disadvantages of the vro configuration by comparing with general security vulnerabilities. Administrators can precisely adjust their existing router security configurations to better meet their enterprise needs. Cisco SDM can also be used for routine operations, such as monitoring, fault management, and troubleshooting.

Router Security Configuration

In addition to vro security configuration, Cisco SDM can also help you quickly and easily perform vro service configuration, for example: lan wlan, WLAN and WAN interface configuration, dynamic routing, DHCP server, QoS policy, and so on. By using the LAN Configuration Wizard, you can not only assign IP addresses and subnet masks to Ethernet interfaces, but also enable or disable DHCP servers. The WAN Configuration Wizard allows you to configure xDSL, T1/E1, Ethernet, and ISDN interfaces for WAN and Internet access. In addition, for serial connections, you can also implement frame relay, Point-to-Point Protocol (PPP), and advanced Data Link Control (HDLC) encapsulation. In addition, Cisco SDM allows you to configure static routes and common dynamic routing protocols, such as "Open Shortest Path First" (OSPF) and "route information protocol" (RIP) version 2nd and "enhanced internal gateway routing selection protocol" (OSPF ).

Now, using Cisco SDM, you can easily apply QoS policies to any WAN or VPN channel interface. The QoS policy wizard automatically executes the Cisco Architecture Principles of QoS policies to effectively distinguish real-time application speech or video) structured Query Language for key business applications [SQL], Oracle, Citrix, routing protocol, etc.) traffic and other network traffic Web emails ). With network-based application recognition (NBAR) monitoring in Cisco SDM, users can inspect application-layer traffic in real time in a visualized manner, and continuously analyze the impact of QoS policies on various application traffic.

Monitoring and Troubleshooting

In monitoring mode, Cisco SDM can quickly display the status and performance data of important Router Security Configuration resources in a graphical manner, such as interface status normal or abnormal), CPU and memory usage. For wireless models, Cisco SDM fully supports real-time 802.11a/B/g interface statistics. Cisco SDM can use integrated routing and security features on routers to diagnose WAN and VPN connections in depth and eliminate faults in a timely manner. For example, when a VPN connection is rectified, Cisco SDM checks the router configurations and connections from the WAN interface layer to the IPSec Crypto Map layer. When you test configuration and remote peering connections at each level, Cisco SDM provides the success or failure status, possible causes of failure, and repair suggestions from Cisco TAC.
