Hello, I am quark. Yesterday (09.15) 3 o'clock in the morning, Meranti came, immediately weeping, flying debris, water and electricity, the coastal area is really hurt, but I still came back, yesterday did not update, and today together. Last time we learned how hackers are preparing for an attack, today we are officially in the attack phase, learning How to sniff the network to get information about the specific situation of the target host

You can reduce the pressure to protect your network by using the following four steps. Here are some ways to strengthen your network defenses. Recently, Microsoft is promoting that if you want to get a truly secure network, you have to focus on 5 important areas. These areas include perimeter protection, network protec

and applications. With the multi-carrier traffic scanning engine, the gateway can monitor Web traffic in real time and classify new sites and dynamic content in real time, so as to actively detect security risks and prevent malware intrusion. Websense Web Security Gateway supports ThreatSeeker Network technology, prov

audit system can see more detailed information, such as the download file name, file type, size and so on. It is helpful for administrators to monitor whether network resources are legitimately used. Fast location of attack source and target In the case of Internet worm propagation, the network behavior of the host infected by the worm will be different from t

of small organizations to enjoy convenient networking. 1. Check for security In order to keep abreast of the security status of the wireless network of the Organization, we should regularly check the Intranet and Internet usage of the Organization and the working status of core network devices, and make a detailed ins

In the construction of the new network system, network security is the primary consideration for the majority of users. In general, users are willing to invest heavily to buy advanced firewalls and software. However, the vast majority of users have little knowledge of the security of the

wireless peer-to-peer Security WEP) for encryption, because the latter is far more vulnerable than the former. To use WPA, you can update your WAP and/or your wireless NIC, but this is worth the cost. If you have not continuously updated your operating system, you may also need to install the WPA client on your computer. However, if you are safe with the latest Windows XP service pack, or you can switch to Windows Vista to support WPA, which also pro

perimeter network so that intruders cannot attack a wired network even if the wireless client is cracked. Users on the wireless network are also required to use VPN when connecting to a wired network. Use an IDs or response sensor to monitor all online on the wireless

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:

performance. The tester can use a passive scan mode without logging on to the AP. In passive mode, the wireless network card of the tester only receives signals and does not send data. If the RF quality can meet the requirements, the administrator can log on to the wireless network in client mode for testing, such as logon test, PING, and throughput test. In general, the Administrator must verify whether t

XP service pack, or you can switch to Windows Vista to support WPA, which also provides other security protection ). Wireless Network Security for large organizations As the company grows, it is more important to restrict the use of wireless networks. It is important to establish a policy to prevent the emergence of unspecified wireless access points and to regu

attacker.At this point the attacker controls the traffic between PC A and computer B, and he can choose to passively monitor traffic, acquire passwords and other secret information, and falsify data to change the communication between Computer A and computer B.4, the harm of ARP spoofingARP spoofing can cause the target computer to fail communication with the gateway, which will lead to traffic redirection, and all data will pass through the attacker

Possible types of attacks on Linux Network "Denial of Service" Attack The so-called "Denial of Service" attack means that hackers use destructive methods to block the resources of the target network, temporarily or permanently paralyze the network, so that the Linux network server cannot provide services for normal use

intranet, Or implanted in the back door by an attacker, leading to disastrous consequences. Therefore, to filter inappropriate content, to forcibly remove malicious code and viruses, to manage, monitor and supervise employees to use the Internet correctly, is the urgent task to improve the profit of enterprises. the security of the chat tool The chat tool here refers to the real-time information exchange t

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

The development of wireless network technology can be described as rapid. How should we set the network for many of our network technicians in the Enterprise? Next we will summarize nine methods to address enterprise network security. Generally, the devices used by hackers c

can access a service that does not exist or is opened. Wireless Network Security Settings-monitoring network intruders Users should always monitor network activities and ensure that they can track their trends. The more users, especially administrators, learn about maliciou

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 swit

protocols and convert them accordingly. Therefore, a vswitch that uses network layer information to define a VLAN is less efficient than a vswitch that uses data link layer information. 2. Enhanced Network Security Broadcast on a shared-bandwidth LAN will inevitably cause security issues, because all users on the
