【REVIEW】 enterprise network security, no more than exists in the following areas: malicious attacks, viruses.There is no absolute security, only relative safety, relying on a single software or hardware to support the task from the enterprise network, it is not enough, the network is from a pre-dominant factor.
With the extension of the network rise and popularity, more and more companies are implementing units and the network office, saving a large extent, the time difference to communicate with customers, although the Internet has brought revolution in office automation, but also leadto a number of commercial hackers and viruses!This makes the company very high-level headache, but as long as the defense of good safety net measures, easily read a newspaper or a cup of tea no problem!
Let us work together to understand the points of major damage!
First, malicious attacks
Good people and bad people everywhere in the world, the same network, for a man not by the software or technology to protect the enterprise's external network is concerned, will withstand the test of a large number of network attacks, although sometimes these attacks are aimless,but it can not do break through the defense to reach a computer outside the network within the network, ranging destroy the entire network, while in access to critical business information.In particular, some unscrupulous rookie-level malicious users, the network will enable enterprises to become full of holes, a mess!The attacker did not pay attention to strategies for SMEs relatively large number of security threats.
Second, Trojans harm
The virus is always a hot topic on the Internet, network security of enterprises occupy a large part of the ratio, once the malicious virus infection was of considerable interest, then the business can only hope machine sigh up!The virus has several notable features: infectious, invisible, latent, destructive, triggered.This time the most widely spread worm-like virus and a lot of attacks on procedures, use of system vulnerabilities related to communication, while the infection itself does not target specific, random and channeling, but for some worm-type virus for a few minutesThe infection can easily within the hundreds of thousands of computers, spread quite amazing ... ... a time bomb, Trojan horse known, the most ancient allow enterprises to headache, if not a disposition of that business-critical information onYangruhukou a steady flow of leaks, which caused thousands of losses to the enterprise!
The software security preparedness
Since there is another impact on the enterprise security hazards so that what are you waiting for?Quickly erected a network isolation with it!
1, the system patches
Enterprise computer must have the necessary computer compartment to the trigeminal every five to every Bubu, branded all kinds of loopholes in the new patch, so that malicious users will not be controlled by the extreme procedures, expert in Microsoft considered, but loopholes in this regardAfter the Illuminati is also known, but professional website often than enterprises to understand the information, I often see more of the appropriate site is essential!
Second, the firewall application
Firewall bluntly, that is, between the machine and set up a network of checkpoints, the preparation can be achieved through certain procedures and malicious attacks illicit interception capacity!For businesses, the firewall protection of an enterprise's internal network information security, even if a corporate internal network users to access the Internet, have breached the firewall rules, 也会 blocked by a firewall immediately notify the enterprise network managers can not only prevent Wenjian leakage,better serve to prevent malicious users from the Internet all the malicious access or attacks, malicious users are in the hands of every move.If the person is a Trojan used in control technology, then the firewall can also cut the other side of the horse foot 11!And to determine the Trojans extended enterprise income from the land itself!Enterprise Firewall the most significant feature is to provide a double hot backup capabilities to meet the business requirements of the firewall more reliable, when the time of the failure of the primary firewall, backup, firewall, the firewall can automatically take over the main and stable operation of the functioncarefree way to protect the normal operation of enterprise networks, network security guard to take up the duties.
Third, anti-virus software process
Superior performance of the antivirus software as a competent doctor, and always be able to prevent all diseases, including the ability to anticipate the virus, and virus database provided by merchants reaction time whether to update the rate, which to a large extent determinethe company's ability to cope with the virus struck, reducing the severity of confidential leaks and damage degree!Greater protection to the corporate network flow!Anti-virus software available under the virus contagious, hidden high, long incubation period, the destructive practices of extreme interest and trigger different, tailored to develop.
Natural anti-virus
1.Boot sector virus can be, and clear presence of the virus in the computer memory, and restore the changes made to the virus on the memory!
2.Implementation of online monitoring, real-time anti-virus, unknown virus in the forecasting analysis using the code!
3.To track the source of the virus, accurate positioning the site, and credited the report file to achieve the rapid analysis for enterprise network administrators to countermeasures.
4.Charles Xie virus manufacturing machines to produce the virus, regardless of how the virus changes, is capable of analyzing all kinds of DVD, VCD discs, all compressed to penetrate anti-virus scanning, and provides a virus disaster recovery!
4, Trojan Solutions
For the general ordinary horse, by the firewall and antivirus software audits with the use of enough let ashes, but stubborn horse, it must rely on the enterprise network managers analyze.Trojans are usually admitted enterprise computer products with an application process will be random from the start, and take up some memory, where the class can view the process of analysis and comparison software to find out the behind the scenes EXE murderers!And Shun-Tang-style touch to solve Trojan laowo melon!The Trojan horse is simply occupy several areas.
Detection of three methods
1, open the Start menu program group in the start-up projects to see which documents the existence of a strange start.
2, in the Start menu items to input run msconfig, the system will pop up "System Configuration Utility."
At this point if view the system.ini, win.ini, startup group started the project, "shell is equal to Explorer.exe", if not possible in the horse.
3, to the registry check in the Start menu's Run key in input regedit, open the Registry Editor, expand the branch registry under HKEY-LOCAL-MACHINESoftwareMicrosoftWindowsCurrentVersionRun to see if there are strange key startup files.Of course, there are many places in the registry to hide Trojans, the best way is to HKEY-LOCAL-MACHINESoftwareMicrosoftWindowsCurrentVersionRun or other Trojan horse program to find primary key below the file name, file name and through its comprehensive search of the entire registry wasknow it has a few hiding places, and then to 11 and clear!
Five, enterprise Notes
There is no absolute security, only relative safety!Although many of the past two years, the emergence of integrated information security equipment in the overall cost and ease of use, small and medium enterprises provide a lot of attractive features, but not enough to solve the information security company in the field of the plight suffered.Rely on a single software or hardware to support the task from the enterprise network, it is not enough, the network is the pre-factors from the dominant position.Enterprise network administrators must be strengthened sense of service, experience and speed of solution to the problem and try to find the first time to come up with viable solutions, put into practice, this is the best strategy!
