Several measures to ensure network security
1 to ensure hardware security.
Common hardware security measures mainly include the use of UPS power supply to ensure that the network can run under continuous voltage; Lightning protection, waterproof, fire prevention, anti-theft, anti-electromagnetic interference and safety protection of storage media.
2. Ensure system security
Install antivirus software and update system patches in time. Turn off unnecessary services and permissions as much as possible. For foreign storage media, the virus must be killed before use.
3, defense system and backup recovery system
Firewall can be used to realize security functions such as access control, identity authentication and access audit between different areas. Intrusion detection system (IPS) is a reasonable supplement to firewall, which can help the system to deal with network attacks and improve the integrity of information security infrastructure.
4, security audit and system operation and maintenance
Monitoring network content and authorized normal internal network access behavior can help us understand the situation of clients and servers in the network, abnormal processes and hardware changes, and the repair of system vulnerabilities and patches.
5, personnel management and system security
Strengthening the safety awareness of computer personnel, improving their safety quality, sound rules and regulations and an effective and easy-to-operate network security management platform are important conditions for doing a good job in network security.
How can we ensure the security of personal information and how should we protect it?
Recently, many news reports have leaked personal information, and people pay more and more attention to the protection of personal information. Personally, I think that apart from legislating in this respect to strengthen the protection of personal information. We should also start from ourselves and strengthen the awareness of personal information protection. Usually, there will be some short films about this knowledge when you take public transportation such as subway and bus. I searched online, and Gu 'an has a professional FLAS film about information security, including personal information security, which is very interesting and practical. If you are interested, you can search ~
How to effectively protect information security?
Strengthen the management of operation and maintenance audit, conduct safe, effective and intuitive operation audit on the management and maintenance of internal databases, servers, network equipment and safety equipment, make detailed records of policy configuration, system maintenance and internal access, provide fine-grained audit, support the full playback of the operation process, and provide multi-angle and all-round security protection before, during and after the event; Auditing and monitoring data access behavior, focusing on strengthening database auditing technology, monitoring and auditing data warehouse access behavior, and timely warning and stopping ongoing database theft; It can also provide effective electronic evidence; Angkai technology operation and maintenance audit system and database audit system give you the strongest information security protection.
How to ensure information security
First, transparent encryption software. A large number of data documents and various files are generated by enterprise users every day, and these files need to be encrypted in the process of generation, use, storage and circulation. This requires the use of enterprise-level "transparent encryption software".
Second, file delivery management. When you need to send a file, set reading times, aging, editing rights, screen capture restrictions, etc. Ensure that all kinds of documents play a protective role when sent to customers. At present, there are many such software products for document delivery management. It is understood that Tian Rui Green Shield software includes transparent encryption and outbound security system to ensure enterprise information security.
How to ensure personal computer information security
Protect your computer at ordinary times and give some advice.
1, still need to install anti-virus software. It is necessary to update the virus database in time and install a firewall (to prevent Trojan horses and hacker attacks, etc.). ) regular anti-virus to maintain the safety of computer operation;
It is suggested that the landlord can install Tencent computer housekeeper, which integrates free professional security software and anti-virus management (only need to download one copy), occupying less memory, good anti-virus, good protection and no error killing. We have embedded anti-virus engines in world-class anti-virus software such as cloud anti-virus engine, anti-virus engine, Jinshan cloud anti-virus engine, AVIRA anti-virus engine, Red Umbrella and anti-virus repair engine!
Among them, software upgrades, bug fixes and garbage cleaning are all set automatically and regularly, which is necessary for lazy people.
2. Fix vulnerabilities and patches; Open Tencent Computer Manager-Toolbox -Bug Fixing
3. Don't go to some unknown websites at ordinary times, and don't download things casually;
4. Beware of portable storage devices (such as USB flash drives). Recently, the U disk virus is quite rampant);
5. Do not enter unknown websites or receive strange emails. After downloading the compressed package file, scan the virus first.
6. Close unnecessary ports.
7. If you have time and energy, learn some common computer skills and knowledge;
Finally, I want to say that if you are really careful at ordinary times, but you are still poisoned, there is nothing you can do! (It is a good choice to back up the system with Ghost)
How to improve the security ability of network information
Sound network and information security measures With the popularization of enterprise networks and the expansion of network openness, sharing and interconnection, people pay more and more attention to network information security. A secure computer network should have reliability, availability, integrity, confidentiality and authenticity. Computer network should not only protect the security of computer network equipment and computer network system, but also protect data security. Network security risk analysis The vulnerabilities of computer system and communication facilities are isomorphic, which pose a potential threat to computer network. Information networking makes information open and information utilization free, which leads to the sharing and interaction of information resources. Anyone can publish and obtain information online. In this way, the problem of network information security has become the core problem that harms the development of the network, and the information infringement caused by the connection between the Internet and the outside world is particularly serious. At present, the unsafe factors of enterprise network information come from viruses, hackers, Trojans, spam and so on. Computer virus is a destructive program that endangers the security of computer system and network. It can directly destroy computer data and information, and also occupy a lot of disk space, seize system resources, thus interfering with the normal operation of the system. With the development of Internet technology, the maturity of enterprise network environment and the increase of enterprise network application, the ability and mode of virus infection and transmission have changed from simple to complex and hidden, especially the Internet environment and enterprise network environment provide an environment for virus transmission and survival. Hacking attacks have become frequent events in recent years, and the incidents of server attacks in the network are endless. Hackers use the loopholes and defects in computer systems, network protocols and databases to invade computer systems by means of password cracking, trap doors, back doors, Trojan horses, etc., destroying information or occupying system resources, so that users cannot use their own machines. Generally, the networks of large enterprises have Internet connection and provide services such as WWW and email. Therefore, the internal network of an enterprise connects with the outside through the Internet and exchanges a lot of information, of which about 80% of the information is e-mail, and more than half of the e-mail is spam, and it is still increasing year by year. Information security in enterprise LAN can not be ignored. Nodes in the network share network resources through the network * * *, and may inadvertently store important confidential information or personal privacy information in the * * * shared directory, thus causing information leakage; There is even a phenomenon that internal personnel write programs to spread through the network or use hacker programs to invade other people's hosts. Therefore, network security should not only guard against external networks, but also guard against internal networks. Network security measures Therefore, there are many network security risks to consider. Therefore, enterprises must adopt a unified security strategy to ensure network security. Complete security technologies and products include: identity authentication, access control, traffic monitoring, network encryption technology, firewall, intrusion detection, antivirus, vulnerability scanning, etc. The causes of safety accidents include technical factors, management factors and omissions in the design of safety architecture. 1. Measures to prevent external intrusion (1) Network encryption (Ipsec) IP layer is the most critical layer in TCP/IP network. As a network layer protocol, the security mechanism of IP can provide transparent coverage security protection for various application services in its upper layer. Therefore, IP security is the basis of the whole TCP/IP security and the core of network security. IPSec is the only protocol that can provide security for any form of Internet communication. IPSec can provide security through data flow or connection, so it can achieve very detailed security control. For users, different levels of security protection can be defined according to different requirements (that is, IPSec channels with different protection strengths). IPSec provides security services for network data transmission, such as data confidentiality, data integrity, data source authentication and replay prevention. , so that when data is transmitted through the public network, there is no need to worry about being monitored, tampered with and forged. IPSec achieves these goals by using various encryption algorithms, authentication algorithms, encapsulation protocols and some special security protection mechanisms. These algorithms and their parameters are stored in SA(Secur) at both ends of IPSec communication. ......
How to ensure information security
Users find the importance of personal computer information security. When your computer is stolen, robbed, hacked, or obtained by others due to force majeure, how to ensure that your computer information loss is minimal and your secret information is not obtained by others? This deserves the attention of all laptop users. The Yanzhaomen incident sounded the alarm for ordinary PC users: Who doesn't have some important information? Who doesn't have some secrets that only belong to themselves? Worry may even lead to some fears, and no one knows when something unexpected will happen to them. So I summarize a set of personal computer security scheme for your reference. First, the classification of local information to manage personal information, we must first classify our own information, mainly including: mail, documents (DOC, XLS, PPT, PDF, TXT), files (other types), photo files, video files, etc. Then, according to the level of confidentiality, this information is divided into three levels. The most confidential information is top secret, followed by secret, and files without confidentiality are ordinary. Second, the account security system does not join the domain. The local computer has only one administrator and one password. You need to log in with a password to access the system. Commonly used network service accounts also need to log in with passwords. Regarding the password security of local computers and network service accounts,
How to establish a complete information security system
How to Cultivate Managers' Innovative Thinking
1. devote yourself wholeheartedly. The first step is to devote yourself wholeheartedly to developing your own innovation ability. Don't give up trying. Set goals, get help from others, and spend some time every day developing your innovative skills.
Being an expert is one of the best ways to cultivate innovative ability. Through in-depth understanding of the theme, you will be able to better think about novel or innovative solutions to problems.
3. reward your curiosity. A common obstacle to developing your innovative ability is that being curious is an illusion. When you are curious about something, don't scold yourself, reward yourself. Give yourself a chance to explore new topics.
It is important to realize that sometimes innovation is a reward in itself, but it is equally important to cultivate intrinsic motivation. Sometimes, the real reward of innovation lies in the process itself, not the product.
Willing to take risks When you start to develop your innovative skills, you must be willing to take risks in order to improve your ability. Your efforts may not be successful every time, but they will still improve your innovation ability and cultivate skills that can be used in the future.
6. Build self-confidence. Lack of self-confidence in your ability will inhibit your creativity, which is why it is so important to build self-confidence. Record your progress, praise your efforts and always try to reward your creativity.
7. Invest time in innovation If you don't invest time in innovation, you won't be able to develop your innovative talents. Set aside some time each week to focus on certain types of creative projects.
8. Overcome negative attitudes that hinder innovation According to a study published in the Proceedings of the National Academy of Sciences in 2006, positive emotions can improve your creative thinking ability. According to Dr. Adam Anderson, the lead author of this research report, "If you are doing a job that requires creativity, or working in a think tank, you will want to have a good mood." Focus on eliminating negative thoughts or self-criticism that may damage your ability to innovate.
9. Overcome the fear of failure and worry that you may make mistakes or your efforts will fail, thus hindering your progress. Whenever you find yourself feeling this way, remind yourself that mistakes are only part of the process. Although you may stumble on the road of innovation occasionally, you will eventually achieve your goal.
10. Brainstorming to stimulate new ideas is a common technology in academic and professional fields, but it can also be used as a powerful tool to develop your innovative ability. Put aside your own judgment and self-criticism, and then start writing down relevant ideas and possible solutions. The goal is to generate as many ideas as possible in a relatively short time. Next, focus on clarifying and refining your own ideas to achieve the best choice.
1 1. Recognize that most problems have multiple solutions. Next time you deal with a problem, try to find various solutions. Don't simply rely on your initial idea, take time to think of other possible ways to deal with this situation. This simple action is a good way to cultivate your problem-solving ability and creative thinking.
12. Write an innovation diary and start to write a diary to record your innovation process and track your creativity. Keeping a diary is a good way to reflect on what you have done and find other possible solutions. Diary can be used to save ideas for future inspiration.
13. Creating a brain map (mind map) is a good way to connect various ideas and seek innovative answers to questions. To create a brain map, you must first write down a central topic or word, and then link related factors or ideas around the central word. Although similar to brainstorming, this method allows branching ideas and provides a very intuitive way to see how these ideas are interrelated. (Translator: Recommended open source brain mapping software FreeMind)
14. Challenge yourself When you have some basic innovative skills, it is very important to constantly challenge yourself to further improve your ability. Find more difficult solutions, try new things and avoid always using the solutions you have used in the past.
15. Try the "six hats" technique. "Six hats" means looking at the problem from six different angles. In this way, you can generate more ideas instead of looking at the problem from one or two angles as in the past. Red hat: Look at the problem with emotion. How do you feel? White hat: look at the problem objectively. What is the truth? ......
How to ensure personal computer information security
Due to the popularity of notebook computers, we hope that more and more users will find the importance of personal computer information security. When your computer is stolen, robbed, hacked, or obtained by others due to force majeure, how can we minimize the loss of your computer information and prevent your secret information from being obtained by others? This deserves the attention of all laptop users. The Yanzhaomen incident sounded the alarm for ordinary PC users: Who doesn't have some important information? Who doesn't have some secrets that only belong to themselves? Worry may even lead to some fears, and no one knows when something unexpected will happen to them. So I summarize a set of personal computer security scheme for your reference. First, the classification of local information to manage personal information, we must first classify our own information, mainly including: mail, documents (DOC, XLS, PPT, PDF, TXT), files (other types), photo files, video files, etc. Then, according to the level of confidentiality, this information is divided into three levels. The most confidential information is top secret, followed by secret, and files without confidentiality are ordinary. Second, the account security system does not join the domain. The local computer has only one administrator and one password. You need to log in with a password to enter the system, and the commonly used network service accounts also need to log in with a password. For the password security of local computers and network service accounts, please refer to another article of Moonlight Blog, Security Protection Measures for Ten Common Network Passwords. At present, it is safest to use Google's services for network services. Users need to have two Google accounts, one is their most commonly used Google account, used for ordinary and secret mail or file operations, and use this account to communicate with the outside world. The other is a top secret Google account. All emails and files defined as top secret information are kept in this top secret Google account. No information is stored on the local computer, and the password of the top secret Google account is not stored locally. Only the invisible window or privacy mode is used to access this top-secret Google account. Third, the processing tools for daily operation documents are: mail-Gmail; Documentation-Google Docs; Instant messaging–-gtalk (built-in Gmail); Other documents–-Dropbox, TC, WinRAR, etc. In the daily file operation, we should pay attention to using the network services of large foreign companies as much as possible, and have the function of data export to avoid data loss caused by service closure. We recommend Google's service. Mail and documents should be placed on the server as much as possible, and mail clients should be used as little as possible, and Gmail and Google Docs services should be used more. A large number of files can be saved through cloud storage services such as Dropbox, and files with top secret information can also be synchronized through another Dropbox account. After the synchronization is completed, Dropbox will be closed and local files will be deleted. If you need to back up confidential or top secret files locally, you need to use file encryption technology. The simplest method is to use WinRAR and other tools to encrypt and compress the password and set a long password with more than 8 digits. Fourth, the steps to deal with emergencies First of all, the most important thing is to immediately modify the commonly used Google account password. You can click here to modify it in the browser, and your mobile phone can also log in to Google through your mobile browser to modify your password. Top secret Google account is relatively safe, because the password is not stored locally, and it is always accessed through private mode. Secondly, modify the password of Dropbox, and disconnect the permissions of the lost computer after logging in to Dropbox to prevent others from modifying your network files. Then, modify the passwords of other network applications, such as SNS, Weibo, blog and other systems. Usually, passwords are kept locally. After changing the password, the user must log in again to access the password. I use the figure below to show the whole computer information security scheme. After these operations, even if our computer is lost, others can only get the local ordinary files of the computer, but can't get the important confidential files stored on the server, which can prevent our confidential data from being obtained by others, thus ensuring the information security of the user's personal computer.
How to Strengthen Personal Information Security
Personal self-protection is the first important link of network privacy protection. Netizens have many ways to protect their online privacy.
The first is to isolate personal information from the Internet. When there is important information in a computer, the safest way is to disconnect the computer from other computers connected to the Internet. This can effectively avoid the invasion of personal data privacy and the economic loss caused by database deletion and modification. In other words, it is best not to store important personal information in the computer that netizens use to surf the Internet. This is also a common practice in many units at present. The second is to use encryption technology when transmitting files involving personal information. In computer communication, information is hidden by cryptographic technology, and then the hidden information is transmitted, so that the information is stolen or intercepted in the transmission process, and the thief cannot know the content of the information. The sender uses the encryption key to encrypt the information through encryption equipment or algorithm and send it out. After receiving the ciphertext, the receiver uses the decryption key to decrypt the ciphertext and restore it to plaintext. If someone steals it in transmission, they can only get incomprehensible ciphertext, thus ensuring the security of information transmission.
Third, don't leave personal information on the Internet easily. Netizens should be very careful to protect their information, and don't casually disclose personal information including email addresses online. Now, some websites require netizens to get some "membership" services by logging in, and some websites encourage netizens to leave personal information by giving gifts. Netizens should pay great attention to this. Just because a form or application needs to fill in personal information doesn't mean that you should disclose it automatically. If you like, you can turn passivity into initiative and use some false information to deal with the excessive demand for personal information. When required to input data, you can simply change the letters of your name, postal code and social security number, which will associate the input information with a false identity, thus * * * introducing data mining and feature testing technology. Be more careful about personal information that uniquely identifies the identity class, and don't disclose it easily. This information can only be used for online banking, passport reapplication or dealing with trusted companies and institutions. Even if you must leave personal information, you must first determine whether there are policies and measures to protect the privacy and safety of netizens on the website.
The fourth is to install a firewall in the computer system. Firewall is a way to ensure network security. Firewall can be installed on a separate router to filter unwanted packets, or it can be installed on the router and the host. In terms of protecting network privacy, firewall mainly plays the role of protecting personal data security and personal cyberspace from illegal invasion and attack.
The fifth is to use software to counter Cookie and completely delete files. As mentioned above, websites that set up Cookie information can read the personal information of netizens with the help of browsers, and track and collect their online habits, which poses a threat and violation of personal privacy. Netizens can take some software technologies to counter Cookie software. In addition, because some websites will send some unnecessary information to the computers of network users, netizens can also protect their network privacy by clearing the data temporarily stored in memory after surfing the internet every time.
Sixth, the protection of minors' network privacy should be carried out with the help of parents or guardians and related software technologies, in addition to educating minors on privacy knowledge and media literacy.
