legitimate application of SQL statements all captured, unified into the "white list", to prevent legitimate statements are false, through the semester perfect period, and then switch to the protection period, At this point, if there is a bulk export of sensitive data through the Web Access application backdoor, the database firewall will report "new statement", such statements belong to the "gray list" statement, the security administrator to judge t

1. The existence and development inevitability of IDS (Intrusion Detection System) (1) complexity of network security itself, and passive defense methods are not powerful. (2) related firewalls: devices with network boundaries can be attacked by themselves, and some attacks are poorly protected. Not all threats come from outside the firewall. (3) Easy intrusion:

equipment, and make a detailed inspection record. At the same time, we should also increase the intensity of the wireless network in the vicinity of the wireless LAN work environment for dynamic monitoring, a certain time also need to the unit of the Network system security assessment and audit; In addition, for organ

interruption, the system supports setting off-line policy and time limit; Under normal policy permissions, users can use security domain and quarantine data off-line normally, but prohibit unauthorized export and network outbound, the system will record the operation log and audit in detail. 　　7. Data Security Outgoi

steal your network information, you can use your system resources to work for him, More typical is the "botnet." Security issues from outside the network, focusing on protection and monitoring. From the internal security of the network, the personnel is controllable, can t

skills here are also very useful for IIS administrators with a strong budget. First, develop a set of security policies The first step to protect Web servers is to ensure that the Network Administrator understands every rule in the security policy. If the company's top management does not regard server security as an

How to create a "clean" network environment, not only in the use of how powerful security equipment, that is only a symptom and not the root causes, the right approach should be to create a new security infrastructure to build a new network order. Recognize the "standard" and "This" of

Packet Inspection) technology. This kind of firewall technology through a module called "State Monitoring", without affecting the normal operation of network security on the premise of the use of data extraction methods to monitor the various levels of network communication, and according to a variety of filtering rules to make

should also increase the intensity of the wireless network in the vicinity of the wireless LAN work environment for dynamic monitoring, a certain time also need to the unit of the Network system security assessment and audit; In addition, for organizations involved in the organization of core privacy information and t

Logs and security logs from these systems to your extensive monitoring infrastructure.6. Audit: include the recently integrated network in your regular internal and external audit content to ensure the effectiveness of the implementation and control of measures.If you are responsible for data

up for some of the vulnerabilities and risks. Experienced administrators can also use hacker tools to simulate attacks on the network to find Network Vulnerabilities. 4. Intrusion Detection Intrusion detection technology is designed and configured to ensure the security of computer systems. It can detect and report unauthorized or abnormal phenomena in the syste

When talking about network security, I want to learn more or less about it. The so-called network security means that the hardware, software, and data of the network system are protected, measures to ensure continuous and reliable operation of the system without accidental o

Regarding the Security protection of Cloud computing data centers, CSA (Cloud Security Alliance, Cloud Security Alliance) put forward a total of eight suggestions in D7 of the Cloud computing key field construction guide, four security risks related to network

accidents.Iii. New blocking methods for Intranet Security ProductsTo sum up, there are many problems with ARP spoofing blocking methods. Therefore, Intranet security products should use this method dialectically, qi Ming and stars put forward different ideas in their daily internal network security risk management and

Regardless of the Internet or Intranet environment, the network will always encounter various security threats ", we must find a way to fully understand the network security status of the system, in order to effectively resolve security threats. Many methods are available to

able to distinguish and control the users accessing and accessing the network information. More importantly, the switch should also be coordinated with other network security devices to monitor and block unauthorized access and network attacks. New features for secure switches 802.1X Enhanced

security threats Although low-grade Wireless LAN may bring us a variety of unexpected security threats to the wireless LAN, it may cause a lot of security risks to the information system of the Organization, however, for small-scale organizations that do not have high security requirements, low-grade Wireless LAN can

layers of a network. The traditional way of defining and configuring segmentation is time-consuming and prone to human error, resulting in a large percentage of security vulnerabilities. In addition, implementation also requires deep expertise in device configuration syntax, network addresses, application ports, and protocols. Like isolation,

security, has been attacked by hackers. Firewall The purpose of the firewall is to establish a security control point between the internal and external two networks, and to allow, deny or redirect the data flow through the firewall to achieve the audit and control of the service and access to and from the internal network
