Security deployment and upgrade of cisco switches

There are still prospects for the security deployment and upgrade of cisco switches. There may be no specific cisco switch security mode for the cisco switch Security description, so it may not help you, cisco switch security has become a new highlight in the switch market.

Equipment redundancy is also important

The physical cisco switch security, that is, the redundancy capability, ensures the safe operation of the network cisco switch. No manufacturer can ensure that its products do not fail, but whether the product can be quickly switched to a good device in case of a fault is a matter of concern. Redundant devices, such as the backup power supply, backup management module, and redundant port, can ensure that the backup modules and cisco switches can be assigned security to the network even if the device fails.

Deployment of cisco switch Security

The emergence of cisco switch security greatly enhances the security capabilities of cisco switches at the layer of switches. Cisco switch security can be configured at the core of the Network, as with cisco Catalyst 6500, a modular core switch that focuses cisco switch security functions.

In this way, you can configure the security policy of the cisco switch on the core switch to achieve centralized control and facilitate the monitoring and adjustment of network administrators. In addition, the core switches have powerful capabilities. The security performance of cisco switches is a very expensive task. The core switches can do their best to do this.

Placing the cisco switch security at the network access layer or aggregation layer is another option. In this way, the core of cisco switch security is to put power down to the edge, and implement cisco switch security performance at each edge to block intrusion and attacks and suspicious traffic out of the edge.

Ensure the security of cisco switches across the network. In this way, cisco switch security needs to be configured on the edge. Many manufacturers have introduced cisco switch security for various edge or aggregation layers. They build a strong cisco switch security line around the core like a bastion host. The security of cisco switches is sometimes not alone. For example, the PPPoE authentication function requires support from the Radius server. In addition, some other switches can interact with intrusion detection devices, you need support from other network devices or servers.

Cisco switch security upgrade

There are many new cisco switch security products on the market. They are born with some cisco switch security functions as soon as they are released. How can some old switches be guaranteed by cisco switches. Generally, this problem is well solved for modular switches.

The common solution is to insert new security modules on the old modular switch. For example, Cisco Catalyst 6500 has firewall modules, intrusion detection IDS modules, and other security modules; the 6610 switch of Digital China is equipped with the PPPoE authentication module. Directly inserting the old switch can solve these new problems. If the previously purchased switch is a fixed switch, some competent models need to install new cisco switch security functions by upgrading the firmware.

Prospect of cisco switch Security

As users have higher and higher requirements on the network environment, the security requirements for cisco switches are also growing. Many users believe that it is worthwhile to invest a certain amount in vswitch security to improve the robustness and security of the entire network.

In particular, some industry users have no need to connect to the network. Such as banks, securities, and large enterprises, the loss caused by one or more outbreaks of Network viruses is sufficient to exceed the extra investment in cisco switch security. Cisco switch security has become a new highlight in the switch market.
