2. For modern enterprises that increasingly rely on Internet applications, the ever-changing security threats and changing regulations and standards make it a big problem to maintain a reliable network environment

in today's global economic environment, companies and enterprises have never been so inseparable from each other as now. However, although it is more convenient to do business on the Internet, it is more difficult to ensure the security and reliability of data exchange and communication. For large and small enterprises, the changing security threats and changing regulations and standards make the maintenance of reliable network environment a big problem

here are ten security policies to establish online trust relationship inside and outside the enterprise. Although these strategies are not comprehensive, they focus on the top ten threats faced by enterprises: E-mail system, traditional password security mechanism, identity authentication, phishing and so on

1. Without SSL protection, data integrity will be endangered

SSL server certificates should be deployed for your entire enterprise as soon as possible. SSL is the most widely deployed security protocol in the world. It should be deployed on any server to protect all kinds of confidential and personal information transmitted from browser to server

SSL encryption is one of the most important technologies used to protect websites, intranets, extranets and other server based applications. Without it, the integrity of data exchanged through public and private networks will be endangered, which will ultimately affect business continuity and profits. SSL can protect network access, online contact and digital transactions, because it can establish a secure channel between the server and the user

in the past few years, people's understanding of the advantages of SSL technology has been greatly improved. More and more users pay attention to the padlock symbol that indicates that the session uses SSL encryption

nowadays, thousands of websites have installed X.509 special server digital certificate, which can activate SSL between browser and server. All modern web browsers and servers have integrated the function of supporting SSL. Therefore, from the enterprise point of view, you only need to install the certificate on the server. Once the browser and the server exchange signals, all the data transmitted from one side to the other side are encrypted, which can prevent any eavesdropping that may endanger the security or integrity of the transmitted data

2. Without reliable physical and network security, sensitive enterprise data will be in danger

using firewall, intrusion detection, client PC virus software, server based virus checking, and ensuring the latest security patches on all systems can prevent most types of threats from affecting the company's business, damaging sensitive data, or threatening business continuity

network security involves computer system and network access control, detection and response to intrusion activities. Poor security will bring huge risks: data theft, service interruption, physical damage, system integrity is endangered, unauthorized disclosure of company proprietary information

in order to protect the network access channel, we should start from the basic aspects, such as locking up the unused computers. In addition to the basic aspects, more reliable solutions include the use of key cards, hardware tokens, and biometrics to control access to particularly sensitive areas

firewall is a necessary part of network security. Firewalls restrict access from one network to another, and check and restrict all traffic through the network. Firewalls should restrict access from Internet and one internal network (such as application server) to another network (such as database). It is necessary to consider which IP addresses and ports the firewall should allow. In addition, it is recommended to use multi-layer firewalls for parts of the network with significantly different functions - one for the DMZ, a second for the web server, a third for the application server, and a fourth possibly for the database

intrusion detection system can monitor attacks, analyze and review logs, alarm administrators when attacks occur, protect system files, reveal hacker's methods, indicate which loopholes need to be plugged, and help to track criminals who implement attacks

another indispensable

means is to ensure that the virus and Trojan horse check software on all clients are up-to-date. There are thousands of viruses out there, and each new one is more cunning and destructive than the original one. Recently, several viruses spread by e-mail and spread all over the world have caused great damage and loss. A particularly reliable solution is to run server based virus software on the e-mail transmission system (such as Microsoft Exchange) to prevent the infected e-mail from being transmitted to users or infecting other clients through one client

finally, the simplest and most effective way is to make sure that you have a security patch for each latest version of all operating systems and applications. Hackers are clear about the loopholes in Microsoft's IIS Web server, and always take the site running IIS Web server as the target. Over the years, patches to plug IIS security vulnerabilities can be obtained free of charge, but there are still more than 30% of IIS systems on the Internet without the latest patches. Therefore, it is necessary to reiterate that all security patches should be applied immediately

3. Develop your own PKI system or choose managed PKI service

when a trusted third party expands a complex, secure and expensive public key infrastructure (PKI) and manages it for you, the fully managed security service can enable you to focus on the applications needed to promote the company's business development

public key infrastructure (PKI) is a tool that can use various applications in a way that was not possible in the past. If there is no effective way to issue, revoke and manage certificates, after the company deploys the welfare system on the intranet, it is not expected that employees can only use the system to query welfare information, especially if a large proportion of employees work far away. Similarly, if the access is not secure and reliable, the sales team will not be able to make full use of the company's important system: CRM system. Nowadays, many companies are restricting the use of e-mail, and many companies prohibit the use of instant messaging - all because these systems are not yet secure

the previous generation of PKI is very good in theory, but in fact, it needs to install complex hardware and software, as well as special IT personnel and special security measures to protect the system. Needless to say, all this means huge financial costs. However, PKI has been mature and innovative enough to become an outsourcing part of the application system. Trusted third party certification authority (CA) can build, maintain and manage the public key infrastructure needed by enterprises, and ensure its security. Ca, which provides fully managed services, has expertise in verification techniques and methods. Enterprises need to know the business rules they want to implement and the applications they need to deploy in order to realize business process automation. The integration point is how to use certificates in applications to implement security. Many applications already have certificate ready function, such as browser, e-mail and VPN; The increasing use of certificates has become a general trend

fully hosted security services have several important parts: flexible verification model (how can we know who someone is), management interface (who in the organization is authorized to make changes and control the process), and operation interface (how different groups in the organization can obtain certificates)

most organizations need to outsource their applications to trusted third parties to meet one or more of the following requirements: secure access, secure messaging and paperless transactions. For all large organizations, it is an important requirement that employees can safely access enterprise networks such as intranet and key applications such as CRM system. E-mail or instant messaging programs provide a mechanism to confirm the identity of the sender and protect the content from eavesdropping. Paperless transaction can fully digitize the paper-based process that needs to use the original signature to indicate the content, thus saving the time and cost of paper-based process< Free software can crack the password within 30 minutes

password security is very poor, and it is getting worse and worse, which makes your security system vulnerable to attack. It can enforce strict rules of password usage, thus greatly enhancing this defense capability

with the speed of the computer, the temptation of password cracking is increasing, which is more attractive to those criminals. As more key business systems are connected to the Internet, password cracking can gain more benefits. With downloadable free software, anyone can crack a 6-character password in 30 minutes and an 8-character password in 6 hours

you need to make rules immediately about how people create passwords and how often they change them. Password creation rules include: mixed use of uppercase and lowercase letters; Always have at least one number and punctuation; Don't use the name in your profile; The length should be at least 8 characters. The most important thing is, if you need to use your password continuously, if you input it incorrectly five times, make sure that all passwords are disabled to prevent the behavior of trying to crack the password with brute force. Run the password cracking program inside to find out the password with poor security. Then, we begin to replace these weak passwords with low-cost, outsourced authentication and digital SSL certificate services

5. E-mail will reveal your business secrets

issue digital client certificate for all employees to sign / encrypt e-mail, so as to protect enterprise data and further make employees feel at ease about the source, authenticity and confidentiality of all enterprise communications

secure messaging (think of initial e-mail and subsequent instant messaging and voice over IP [VoIP]) is designed to ensure that only the intended recipient of the message can read it. The more frequently e-mail is used, the more important it is to the company's confidential information. This is especially true for emails sent to

outside the enterprise. E-mail is transmitted from one server to another through the public network in clear text format. Servers along the way can and do save all the messages they receive and have the right to do so. On most e-mail systems, the sender has no control over who can receive the forwarded e-mail messages, and there is no trace of someone receiving the forwarded e-mail messages

any two employees can sign and encrypt messages sent to each other as long as they simply exchange client certificates, so as to ensure that these messages have not been tampered with; The source was confirmed; Any difference between the two

in battle, carefree Chuanqi adds special effects such as shock, crack and fog to the game in a unique way, which makes the battle experience of carefree Chuanqi feel wonderful

4. Compared with the internal skill, the youliqi shield pays more attention to the external protection. Tiredness and a layer of iron man's armor can protect you from the pain of flesh. Moreover, after years of research by blacksmiths in beech City, although the shield can not fly automatically, it is very light and easy to carry.

5. Digital currency is the currency issued by the central bank, and it has nothing to do with Anyi.

6. Mining machine is one of the ways to obtain. It is a kind of network virtual currency proced by open source P2P software. It doesn't rely on a specific currency institution to issue, but is generated by a large number of calculations of a specific algorithm. It uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions economically. The decentralized nature of P2P and the algorithm itself can ensure that the currency value cannot be manipulated by mass proction
any computer can become a mining machine, but the profit will be relatively low, and there may not be one in ten years. Many companies have developed professional mining machines, which are equipped with special mining crystal. They are tens or hundreds of times higher than ordinary computers.

7. When the protagonist fan comes to the palace, the code of creation is taken away by clausa, the minister who plans to conquer the world, and kidnaps king cross. Fan and Kai decide to find clausa, recover the code and save the king. Task 1: according to blacksmith Locke's instructions, every scene that needs to go out from the bottom of the palace to reach the outside of the palace is the hub to all areas. Follow the entrance marked with the road sign of the forest to enter the forest, kill the mutant wild boar in the forest, and get a mutant wild boar tooth. Go back to the palace and have a dialogue with blacksmith Locke. Note 1: after obtaining the task props, the screen will prompt the quantity of task props. You can also go to the task menu to check whether the quantity of task props meets the needs of the task. Note 2: NPCs who hand over tasks have question marks on their heads. Note 3: file it at the exit of the palace. Talk to the soldier. File it often. Task 2: Locke said that two more iron ores are needed to make a hunter's double-edged sword. Go out of the palace to the field, follow the exit below to enter the mine cave (the road sign says the mine cave), press 3 keys in the mine cave to dig, dig out two iron ores and return to the palace to Locke Mining depends on character, EN) task 3: after getting double-edged, enter the palace hall above the palace and have a dialogue with Kai. Task 4: need to build equipment, and then talk to blacksmith Locke. Task 5: blacksmith Locke asked fan to find 2 variant wild boar hairs, 2 variant wild boar skins and 6 iron ores. Boar fur and skins were killed in the forest to get them, and iron ores were g in the mine cave for 6 more. Then he came back to talk with Locke. Locke gave a set of Hunter suits and remember to put them on the menu. Note 3: it's faster to go to the forest to fight monsters. It's suggested to buy a pair of shoes with quick recovery and Lingbo micro step shoes to make it easier to fight. Task 6: after getting the equipment, enter the palace hall and have a dialogue with Kai. Task 7: get out of the palace, walk all the way to the junction outside the palace, walk left into the forest, and walk all the way. After about five scenes, you can see boss and chaotic python. After dialogue, start fighting. Be careful of its left and right impact, it's easy to kill you. Note 4: chaotic Python has strong attack power and thick blood. It is suggested that you buy a knight suit and then fight him. You can also fight monsters slowly and go to lockner to synthesize a set of highly toxic suit and weapons, or buy more medicine (gift bag), or synthesize some medicine. Task 8: after destroying the chaotic python, you can directly go out from the above exit to reach the hub outside the palace, enter the palace, and then go up into the hall to trigger the plot. Task 9: go out from the palace to the hub, enter the upper right entrance, the snow mountain, and go straight in. After five scenes, trigger the plot and meet the sage Moya The snow beasts are more powerful. Don't provoke them now. The worst thing is to have a knight's equipment. If not, fight slowly. Don't be surrounded.) task 10: Kill 10 snow Beasts (white orangutans) in any area of the snow mountain. Go back to talk with the sage Moya. Task 11: go back to the palace again and have a dialogue with Kay. Task 12: talk to Locke and build a new weapon. Task 13: get out of the palace, get to the junction, and enter the entrance in the lower right corner, desert. Hunt two claws and one bone of the rock beast (the lizard), then go to the mine to get two copper ores, and come back to rock. Task 14: after you get the flaming explosion sword, you need to build a rock suit. You can go to the desert or the flaming cave. You need to find 2 teeth, 2 bones, 2 shells, 2 claws and 4 gold mines. When you come back to Locke, Locke will give you a set of rock suits. This set of equipment is very good. Task 15: go to the palace again and have a dialogue with Kay. Task 16: get out of the palace, enter the desert and walk straight in. After about five scenes, you can see the fierce wind and lion, and fight. It's suggested to bring more HP recovery and magic attack. Otherwise, it will be difficult to fight. Task 17: after destroying the lion, return to the palace and meet the sage Moya. Task 18: to defeat the split air Dragon, you need a flying suit. According to the sage Moya's tips, you can find three strange bird teeth, two strange bird shells, three strange bird sharp blades, two strange bird claws, and six alloy ores. The strange bird can be found in all the wild scenes. It's the blue flying creature that you can fight wherever you go. It's better to go to the forest. It's better to fight at a lower level, Alloy ore is more difficult to dig, it is a test of character and enrance, come on dig it. Task 19: after getting the flying suit, you have to go through Moya's final postgraate entrance examination, and go to the arena in the lower right corner of the Palace (that is, the scenes of various stores). You can pass as long as you pass 18 levels. It's a bit difficult. It's better to synthesize the strongest weapons in Locke's weapons store and equip them If you can't do it, buy the holy light suit.) before the challenge, remember to archive. The archive is at the entrance of the arena. Task 20: after passing the postgraate entrance examination in the arena, the plot ends. Go out of the palace, arrive at the hub, enter the Yandong cave in the lower left corner, go to the deepest place, see the split dragon, talk, and eliminate the split dragon. Game clearance.
