Network security is formed in the heart.
As a new form of crime, information crime is increasingly rampant. In order to improve students' awareness of prevention, the school recently launched publicity and education activities on network information security and fraud prevention. Each class actively cooperates with the organization to carry out network information security education within the class and promote daily network security education.
In this activity, the teacher gave a lecture in every class, and let the students have a certain understanding of network information security and fraud through PPT. Through some specific cases, it is pointed out that network fraud means that others use illegal means such as forgery, information theft, data tampering and virus destruction to destroy terminal data, send false information and forge transaction information. It also emphasizes that students' awareness of information security is poor and the present situation of security education is not optimistic. At the same time, the lecture also taught students specific preventive measures by emphasizing information security issues. Tell us that while surfing the Internet, we should pay attention to identifying information, stay away from bad information and surf the Internet in a civilized way. And keep alert to fraudulent information, and form good safety habits and self-protection awareness.
The successful completion of this publicity activity has guided the students to improve their network security ability and self-prevention awareness, and also enabled them to master some preventive measures. It reflects the concern of the school for students, and helps to build a college system with local security, overall security, intelligent security and overall security, and create a good school atmosphere.
Basic content of network security
First, cyber attacks.
1. Attacks on the network can be roughly divided into two categories: service supply and non-service attacks. Attacks can be divided into eight categories: system intrusion attack, buffer overflow attack, deception attack, denial of service attack, firewall attack, virus attack, Trojan horse attack and backdoor attack.
2.ApplicationDependentAttrack refers to an attack on a server that provides a certain service for the network, which causes the server to "refuse service" and makes the network work abnormally. Denial of service tracking attacks have the following effects: consuming bandwidth, consuming computing resources, and crashing systems and applications. , which prevents legitimate users of a service from accessing the services they have access to.
3. ApplicationIndependent Attrack is not for specific application devices, but for the underlying protocols such as network layer. This kind of attack often uses the loopholes in the protocol and operating system to achieve the purpose of the attack, which is a more hidden and dangerous attack means.
Second, information security.
Information security in 1. network mainly includes two aspects: information storage security and information transmission security.
2. Information storage security refers to how to ensure that information statically stored in networked computers will not be illegally used by unauthorized network users.
3. Information transmission security refers to how to ensure that information is not leaked and attacked during network transmission.
The main threats to information transmission security are: intercepting information, tampering with information and forging information.
The main technologies to ensure the information security of network system are data encryption and decryption.
Third, the problem of preventing denial.
Rejection prevention refers to how to prevent users of information sources from not acknowledging the information they sent afterwards, or not acknowledging the account after receiving the information. Authentication, digital signature, digital envelope and third-party confirmation are needed to ensure the legality of network information transmission and prevent denial.
Fourth, the internal security of the network
We sometimes hear the news that a company's customer information was leaked, and it was found that it was caused by a retired employee of the company's background theft. Security protection within the network refers to how to prevent users with legal status from intentionally or unintentionally revealing behaviors harmful to network and information security. To solve the unsafe factors in the network, we must start from two aspects: on the one hand, we can monitor the running state of the network and the working state of users at any time through network management software, and record and audit the use state of extremely important network resources (hosts, databases, disks, etc.). ); On the other hand, it is to standardize and improve the network use and management system and strengthen user training and management.
Verb (abbreviation of verb) network antivirus
At present, viruses can be roughly divided into six categories: boot virus, executable file virus, macro virus, mixed virus, Trojan virus and network language virus. Network antivirus needs to be solved from two aspects: antivirus technology and user management.
Six, network data backup and disaster recovery
No matter how powerful the enterprise is, it can't avoid network disaster. Some are avoidable disasters (such as administrators mistakenly deleting data), and some are inevitable disasters, such as unexpected power failure and line damage. Alipay and WeChat also had several downtime last year. Therefore, network data backup and disaster recovery are extremely important.
In the actual network operating environment, the function of data backup and recovery is very important. Although it can be avoided from the perspective of prevention, it is impossible to completely guarantee that the system will not go wrong.
