1. On the evening of February 6, 360 Network Security Research Institute announced that the world's First Android mining worm broke out, which affected a number of smart TVs, TV boxes, set-top boxes, etc. with the "ADB debugging" switch on. This group of malware is not a traditional Android virus, but a new type of malware specialized in "mining" in the background of Android devices. Within 24 hours, 5000 devices have been infected with Android mining worm, and at present, more than 7000 devices have been infected. China and South Korea are the hardest hit areas of this worm disease.

3. Now the mainstream protection software basically comes with its own real-time monitoring firewall, and general worms can cope with it (what else do you want to do if you really encounter a giant god, such as panda burning incense, and the country can't help it for a while)
first, you need to know about worms http://ke..com/view/226576.htm?fr=aladdin
but as soon as the epic worm appeared, Software killing companies will want to recruit, and Microsoft will also patch for vulnerabilities, so it's the same sentence
frequently make important patches, frequently update the virus library of software killing, and pay attention to network security, and don't blindly open the unknown

3. Rebound Trojan refers to the connection from the inside to the outside. Of course, the firewall of windows can't prevent it (XP system is typical), but now the firewall technology has been improved, such as comodo firewall. If you don't turn on D + protection, it's correct
4 and 5 don't explain much. You know that they are right when you use killing software
6. I don't play programming, and I can't talk nonsense about the answer to question 6.

7. I don't know why you can't cut off the network, but according to my experience, all infected computers must be cut off! After the network is cut off, you can either kill the virus (troublesome), or restore the backup (the fastest, but you need to kill the virus completely, isn't 360 good), or format and reload the system (you still need to kill the virus completely). In short, the disconnected machine must be completely clean and nontoxic after treatment, and the latest patch must be made, and the software for killing soft protection (360 antivirus + guard) must be installed to avoid re infection! In addition, it's better to use netstat - A - N command on the poisoned computer to check the external connection of the machine. If it is judged to be a suspicious connection, the suspicious address will be blocked on the gateway router, and the virus will not be continuously downloaded from the address. How to judge: turn off all programs that may be connected to the network, and then use the command, it is very clear
I have successfully dealt with the problem of burning incense virus and unknown virus in large area of LAN.

Firewalls are classified according to the scope of work and its characteristics, including filtering firewalls, application proxy firewalls and composite firewalls
1, filtering firewall
filtering firewall is in the network layer and transport layer, which can be analyzed based on the address of data source and protocol type to determine whether it can pass. In line with the firewall standards, the information can be transmitted only when the security performance and type are met, and some unsafe factors will be filtered and blocked by the firewall
2. Application proxy firewall the working scope of application proxy firewall is at the highest level of OIS, above the application layer. The network traffic can be isolated completely, and the application layer can be supervised and controlled by a specific agent
Composite firewall is widely used. It integrates the advantages of packet filtering firewall technology and application proxy firewall technology, and abandons the original disadvantages of the two kinds of firewall, which greatly improves the flexibility and security of firewall technology in application practice 
extended data:
through the defense function of firewall in the intermediate process of internal and external network, it can realize the effective circulation of internal and external resources, deal with various security problems in time, and improve the security of information and data. Firewall technology has a certain ability to resist attacks, for external attacks have the role of self-protection, with the progress of computer technology, firewall technology is also developing
10. Firewall
the so-called firewall refers to a protective barrier composed of software and hardware devices, which is constructed on the interface between internal network and external network, private network and public network. It is an image of a method to obtain security. It is a combination of computer hardware and software, A security gateway is set up between Internet and intranet to protect the intranet from the invasion of illegal users. The firewall is mainly composed of four parts: service access rules, verification tools, packet filtering and application gateway,
a firewall is a software or hardware between a computer and the network it connects to (the hardware firewall is used less, such as the Ministry of defense and large computer rooms, because it is expensive). All network traffic flowing in and out of the computer goes through this firewall< According to the English Chinese Dictionary of securities investment, firewall English is a legal barrier within financial institutions that strictly distinguishes banking business from securities business, aiming at preventing possible unfair transactions such as insider information sharing. Use the firewall metaphor not to start a fire
waterproof wall
waterproof wall is a proct trademark registered by Sanli Wangan in 2004, trademark number: 3975196, which is used for intranet anti leakage procts. Today, it has become the representative of Intranet anti leakage procts. We can see that in addition to the formal Shanli waterproof wall, there are many intranet leakage proof procts, which are also called waterproof wall
compared with firewall, it is a security proct to prevent internal information leakage
network, peripheral interface, storage medium and printer constitute the whole way of information leakage. Waterproof wall for these four ways of leakage, in advance, in the event, after a comprehensive protection. Together with anti-virus procts and external security procts, it forms a complete network security system< In the 21st century, with the rapid development of information instry, the Internet is developing rapidly. Accompanied by the increasingly rampant computer virus. Although many enterprises have a certain sense of security, and deployed the network version of anti-virus software and hardware firewall, but in the face of new worms such as SQL rammer, it is still not enough. In the face of today's bad Internet security situation, how can we guarantee the security of the enterprise network< According to the statistics of ICSA (International Computer Security Association), only 7% of the viruses are transmitted through disk, and 93% of the viruses come from the Internet, including email, webpage, QQ and MSN
according to the technical analysis report of China's computer virus epidemic investigation released by the public information and Network Security Supervision Bureau of the Ministry of public security, the proportion of computer transmission through CD-ROM, disk and other storage media has decreased significantly, while the number of virus infection through network download and browsing has increased the most. The proportion of e-mail transmission has also increased. The trend of computer virus networking is more and more obvious. How to effectively prevent network virus is an important topic in the future anti-virus work
at present, the vast majority of enterprises in China are using network version antivirus software + firewall to protect the normal operation of the enterprise network
network version antivirus software is a set of antivirus software deployed in the enterprise network for centralized management. It can check and kill the virus inside the enterprise and ensure the security of the enterprise network system to a certain extent, but it still has great limitations
first of all, the network version of antivirus software is installed on the original operating system, so the stability of the operating system itself and whether there are loopholes have a certain impact on the use of the network version of antivirus software. Secondly, although the network version of anti-virus software can detect and kill viruses, it can not guarantee that viruses enter the LAN from the Internet
moreover, more and more network viruses begin to exploit the vulnerabilities of the operating system to attack and spread. The time from the release of vulnerability patches by operating system manufacturers to the emergence of viruses spreading by using this vulnerability is getting shorter and shorter, and the time that viruses leave system administrators to repair the system is also getting shorter and shorter. However, if the operating system vulnerabilities are not repaired in time, these viruses can easily bypass the anti-virus software and directly infect the computer, which greatly reces the effectiveness of anti-virus software. How to prevent the virus from entering the internal network has become the primary problem faced by the enterprise network security
many enterprises have graally realized that it is not enough to only use the network version of anti-virus software for protection, and more and more enterprises have begun to use hardware level protection procts to cooperate with it, such as network firewall, intrusion detection system and so on. However, for viruses, can these protection procts really effectively intercept network viruses
practice has proved that network firewall still can not really meet the needs of enterprise security protection. The traditional network firewall is like a door, only open and closed two states, and can not monitor the network status in real time. It can only prevent viruses and hackers by blocking IP< At present, there are many kinds of anti-virus walls in the market. Basically, all companies procing anti-virus software are procing anti-virus walls. Anti virus walls are a kind of high-end anti-virus equipment suitable for large networks. At present, the well-known anti-virus walls in the market include anqihua, Kaspersky, trend, rising and CP. These are well-known manufacturers of anti-virus walls. In terms of performance, the anti-virus wall of anqihua still has great advantages. From hardware to software, anqihua's equipment has incomparable technical advantages, and technology decides everything
