Wireless Network security issues should not be generalized. The corresponding security policies should be changed for different network structures and environments. For example, for home wireless networks, encryption is relatively simple and complicated for enterprise networks. We will introduce wireless
rely entirely on this measure. It can also be said that using MAC address filtering is not a life-saving solution for hackers who are desperately cloning MAC addresses and trying to connect to users' wireless networks, however, you must take this measure to reduce network risks.
Set security password
It is critical to set a password for wireless Internet access. Selecting a strong password helps the
With the development of network security technology, apart from firewall and anti-virus system protection, intrusion detection technology has become an effective way to defend against hacker attacks. Although the intrusion detection technology is still evolving, the market for intrusion detection products is growing, and the third wave of network
Before giving you a detailed introduction to the smart wiring management system, let's first understand the principle and mechanism of the smart wiring management system, next, we will introduce the EtherSeal cabling system to ensure network security, provide reliable solutions for high-density intelligent Cabling Management Systems, and make up for security mana
The malicious network behavior of the network server includes two aspects: first, malicious attacks, such as denial of service attacks, network viruses, etc., which are designed to consume server resources, affect the normal operation of the server, or even the network paralysis of the server; the other is malicious in

This article introduces the security threats and defense policies of the network system of the electronic file center, hoping to help you.
1. security threats that affect the network system of the electronic file center.

layer of security. Remember, however, that it can adversely affect network settings and performance. You must enter the SSID manually into the client, which complicates the configuration of the client. This also causes an increase in the discovery request and response packet, thereby reducing the available bandwidth.
8. Do not trust MAC address filtering
Another false notion of wireless

Enter ipconfig/all and press enter to view information about all computer NICs. The "Physical Address" Physical Address) column displays the MAC Address of the computer.
Once you have a list of authorized MAC addresses, you can use the installation soft
format with a higher security factor. After all, the data stored in the FAT format disk partition is easier to access and damage than the data stored in the NTFS format disk partition, in addition, all the security software and encryption software are also for the NTFS format, and the protection for the FAT format is very weak.
In addition, it is best to use specialized
for netForensics in Edison, New Jersey, pointed out: "Once the technology is appropriate and logs are collected, a monitoring program needs to be implemented to evaluate the traps and possible upgrades in the action.
Network and security administrators often spend time collecting log data, but they do not process the data or have no ready-made resources to monitor
SNMP (such as the Internet router), first make sure that the devices have the appropriate patches installed.

Note that this type of SNMP vulnerability is not the only hardware device. This vulnerability also exists in Windows (excluding XP), Linux, some versions of UNIX, some mail servers and commercial servers, and some management tools including HP OpenView and CA Unicenter. This means that if you are using network management tools to
Financial service providers are restricted by a large number of customers' data security protection rules. Gramm-leaching-Bliley Act (GLBA Act) is widely used and abstract, but it requires risk identification and evaluation for all types of networks, implement and monitor security measures, including wireless networks. Other regulations, such as the famous Paymen

11. Prevent Packet sniffing.
Hackers often install the sniffing software on computers that have intruded into the network, monitor network data streams, and steal passwords, including SNMP communication passwords, as well as vro logon and privileged passwords, in thi

Security expert tip: the best way to protect yourself is that you don't need much technology.
1. The request to re-enter the account information, or will stop the credit card account and other messages ignored.
2. More importantly, do not reply to or click on a link to a message-if you want to verify the email message, use the phone instead of the mouse, and if you want to visit a company's Web site, use a browser to access it directly ins
list acl of the vro port to prevent attacks by using the dedicated VLAN. Virtual ACLs can also be used to eliminate the impact of dedicated VLAN attacks.
By limiting the number of MAC addresses on the vswitch port, the technology that prevents the CAM table from being drowned can also prevent DHCP depletion. As RFC 3118 performs DHCP message verification, DHCP depletion attacks become increasingly difficult.
In addition, IEEE802.1X can monitor basic

Note: the preceding four-line command will filter some data packets in the BOOTP/DHCP Application. You must be fully aware of these data packets when using these commands in a similar environment.
11. Prevent Packet sniffing
Hackers often install the sniffing software on computers that have intruded into the network,
Spoofing and reduce the possibility of hackers using the user system to attack another site.
Monitoring configuration changes
After you modify the vro configuration, You need to monitor it. If you use SNMP, You must select a powerful shared string. It is best to use SNMP that provides message encryption. If you do not remotely configure the device through SNMP management, you are advised to configure the SNMP device as read-only. If you refuse to wri
