Both versions have a number of features in common, but SNMPv2 offers enhancements, such as additional protocol operations. A managed device is a network node that contains an SNMP agent and that resides on a managed network. Managed devices, sometimes called network elements, can be routers and access servers, switches and bridges, hubs, computer hosts, or printers. An agent is a network-management software module that resides in a managed device.
Planning Considerations for Secure Management and Reporting Configuring logging for your Cisco routers is a straightforward operation when your network contains only a few Cisco routers.
However, logging and reading information from hundreds of devices can prove to be a challenging proposition and can raise the following issues and considerations: What are the most important logs? How are important messages separated from routine notifications? How do you prevent tampering with logs?
How do you ensure that time stamps match?
What log data is needed in criminal investigations? How do you deal with the volume of log messages? How do you manage all the devices? How can you track changes when attacks or network failures occur? Securing administrative access and device configurations is also a straightforward operation for smaller Cisco router networks.
However, managing administrative access and device configurations for many devices can raise questions such as those listed. Each of these issues is specific to your needs. To identify the priorities snmpv1/v2 read-write access reporting and monitoring, you must get input from management and from the network and security teams.
The security policy that you implement should also play a large role in answering these questions. From a reporting standpoint, most networking devices can send syslog data that can be invaluable when you are troubleshooting network problems or security threats. You can send this data to your syslog analysis host from any device whose logs you want to view.
This data can be viewed in real time, on demand, and in scheduled reports. Depending on the device involved, you can choose various logging levels to ensure that the correct amount of data is sent to the logging device. You must also flag device log data within the analysis software to permit granular viewing and reporting.
For example, during an attack, the log data that is provided by Layer 2 switches might not be as interesting as the data that is provided by the intrusion prevention system IPS.
To ensure that log messages are synchronized with one another, clocks on hosts and network devices must be synchronized. For devices that support it, NTP provides a way to ensure that accurate time is kept on all devices. When you are dealing with an attack, seconds matter, because it is important to identify the order in which a specified attack occurred.
Configuration change management is another issue related to secure management.
When a network is under attack, it is important to know the state of critical network devices and when the last known modifications occurred. Creating a plan for change management should be a part of your comprehensive security policy; however, at a minimum, you should record changes using authentication systems on the devices and archive configurations using FTP or TFTP.
Secure Management and Reporting Architecture Figure shows a management module with two network segments that are separated by a Cisco IOS router that acts as a firewall and a VPN termination device. The segment outside of the firewall connects to all of the devices that require management.
The segment inside of the firewall contains the management hosts themselves and the Cisco IOS routers that act as terminal servers. Secure Management and Reporting Architecture The information flow between management hosts and the managed devices can take two paths: Information flows within a network on which no production traffic resides.
Information flows across the enterprise production network, the Internet, or both. The connection to the production network is only provided for selective Internet access, limited in-band management traffic, and IPsec-protected management traffic from predetermined hosts.
In-band management occurs only when a management application does not function OOB, or when the Cisco device being managed does not physically have enough interfaces to support the normal management connection.
This latter case employs IPsec tunnels. Because the management network has administrative access to nearly every area of the network, it can be a very attractive target to hackers.
The management module has been built with several technologies designed to mitigate such risks.The EC Energy Box is the latest evolution of NRGence™ - ATEN's energy intelligence solutions. It is the Remote monitoring offers secure access with bits SSL encryption, and customizable account policies for user HTTPS, and SNMPv1&v2&v3 (Read, Write, Trap).

The new HP OpenView Network Node Manager SPI for SNMPv3 supports secure SNMP and SNMP management through firewalls. Slideshow.
Remote monitoring offers secure access with bits SSL encryption, and HTTPS, and SNMPv1&v2&v3 (Read, Write, Trap). Event notifications can be monitored via Syslog/SMTP/SNMP trap and by audible alarm for real-time local and remote alerting. The NRGence™ EC Energy Box is the intelligent cost effective solution. Each device in the network, supports its own MIB/TCS file, read/write community, unique IPv4 or IPv6 Address, port number combination and unique values. The devices fully supports SNMPv1, v2, v3; TFTP and Cisco IOS software. The PDU scrambler also provides access to the SNMP script API methods. Management of Networks through RMI.
