1. 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

Where the decimal point is depends on the size of the number, for example, 21.9 yuan, the decimal point is between one and nine, that is 21.8 yuan

for example, 5.24 yuan

5 represents five one yuan, namely 5 yuan. 2 means two one corners, that is, two corners. Four stands for four one points, namely four points

generally, RMB is divided into yuan Jiao units, but sometimes it can be expressed in yuan, ten thousand yuan or hundred million yuan for needs. Know that 1 yuan = 10 Jiao, 1 yuan = 100 Fen, 10000 yuan = 10000 yuan, etc., and vice versa can be expressed by decimal. You can know 1 jiao = 0.1 yuan, 1 Fen = 0.01 yuan, 1 yuan = 0.0001 yuan, you can know 1 yuan, 3 jiao, 5 fen = 1.35 yuan, 675002 yuan = 675002 yuan, etc

extended data:

notes for RMB. If the standard invoice has been printed with the amount unit, the blank of the amount unit before the first amount should be filled with "zero"

2. The word "whole" should be added at the end of the amount in words“ The word "whole" means that the amount of RMB in words has been written completely, and there is no amount after it“ Any number after the word "whole" is invalid

3. The amount of RMB in words cannot be altered. The altered amount is invalid

4. The amount unit of RMB in words "ten thousand" does not have "person" side, while the amount unit of RMB in words "ten thousand" has "person" side

6. The fourth set of RMB binary was issued on May 10, 1988. It is the full version watermark of ancient coins. In addition, in 1990, it also issued the version with the same face pattern and lighter back color. This is the 1990 version we saw

coin collection not only has the value of appreciation, but also becomes another important function. According to a conservative estimate, the fourth set of RMB has been increasing year by year since 2008, with an annual consumption of 8 million copies. The consumption at most indicates the rection of storage. The final result is the price rise of the fourth set of RMB 2.80 version. At present, the stock of 802 is about 700000 to 1.2 million, or 1.5 million to 2.5 million. The scarcity also makes it popular in the fourth set of RMB

nowadays, the market value of the 80 edition is about 32, while the market value of the 90 edition is about 15. However, all of them have to be brand new. If you still have them at home, you should collect them well
