information systems monitoring certification, said: " Isaca is aware of the need to provide a differentiated network security training and certification approach, as global businesses need more effective ways to discover and hire skilled professionals. In today's threatening environment, technicians who rely on unskilled training and certification are like those who rely on a military strategy guide but ha
Is it safe for enterprises to have firewalls? Is the current enterprise network architecture secure? What are the current problems with enterprise network security infrastructure? The new generation of dedicated security agent devices will be an important part of the enterprise's n
specific workstation. This function can improve the security performance of the SNMP service. Configuration command: snmp-server community xxxxx RW xx; xx is the access control list number SNMP Version 2 using MD5 digital identity authentication method. Different vro devices are configured with different digital signature passwords, which is an effective way to improve overall security performance.
Summary
amount of storage space, you can store the user's private key and digital certificates, the use of USB key built-in public key algorithm to achieve user identity authentication. Because the user's private key is stored in the password lock, it can not be read theoretically in any way, so the
Management Solution
SNMP is widely used in the monitoring and configuration of routers. SNMP Version 1 is not suitable for managing applications over the public network because of its low security. The access list allows only SNMP access from a specific workstation. This function can improve the security performance of the SNMP service. Configuration command: sn

The first step in securing your Web server is to ensure that your network administrator is aware of every system in your security policy. If the company's executives do not regard the security of the server

1.1 Wireless Peer-to-peer Privacy WEP (Wired equivalent Privacy)
WEP uses RC4 symmetric encryption at the link layer, and the user's encryption key must be the same as the AP's key to gain access to the network's resources, thereby preventing unauthorized users from listening and access by illegal users. WEP provides a 40-bit and 128-bit length key
.
The default wireless LAN has absolutely no security at all, and almost all APS are configured to turn on WEP for encryption or use the default key provided by the original manufacturer. Because of the open access mode of WLAN, the hacker can enter the wireless network through its default password.
Once the wireless LAN is connected to the enterprise, the hack
First, the preface
My experience tells me: Information security is a kind of artificial confrontation against information protection, it is the competition between man and man in technology and thinking, and it is the war of real "no smoke". The way of attack is multi-faceted and multi-level, so it is a complicated project to establish an effective information security guarantee system, it is a "war" becau
In small and medium-sized enterprises, administrators responsible for network management are also responsible for ensuring network security. Similarly, the requirements of security management and network management are integrated into a broader field of
reception. As long as malicious users have certain knowledge about wireless networks, the security of enterprise wireless networks is quite a problem. Intruders can destroy and intrude through highly sensitive receiving devices.
The default Wireless LAN has no security at all. Almost all APs enable WEP Encryption Based on the default configuration or use the default ke
