This article introduces the security threats and defense policies of the network system of the electronic file center, hoping to help you.
1. security threats that affect the network system of the electronic file center.
Networks, computers, servers, storage devices, system software, and file management information systems are the basic IT environment for the survival of electronic file and file information, and also the risk factors that lead to file information security. Among them, due to the openness of the Internet and the lack of installation configurations of various operating systems and software, there are many security vulnerabilities and defects. For example, the operating systems currently used all have network security vulnerabilities, and the operating system security is not perfect. The security of the firewall products and whether the settings are incorrect must be carefully checked to ensure the security of the firewall. Security threats to the system Intranet, as well as the lack of effective means to monitor the network system, can easily lead to network system paralysis, information theft, data tampering, illegal access, transmission theft, and data interception, potential hazards such as interface interception.
2. At present, the main prevention policies and deficiencies of the network system of the electronic file center are as follows.
At present, the main protection policies of the network system of the electronic file center are firewall technology and intrusion detection technology, but these two technologies have different degrees of deficiency.
(1) firewall technology. A firewall is a combination of components composed of routers or computers in different network or network security domains. The firewall has strong anti-attack capabilities. It is the only portal for information between different networks. It is set to prevent unauthorized communication from entering the protected network, implement effective access, supervision, and control over the network to prevent hacker access and attacks. However, there are also various vulnerabilities in the firewall, and hackers may still use system defects to bypass the firewall for attacks. At the same time, the firewall cannot protect attacks from internal networks and viruses. Therefore, the firewall protects the network passively. The attacked network does not know who initiated the attack on the network, and what method has been taken to achieve the attack purpose, I don't even know what measures should be taken to protect the network. defense measures are relatively passive. This forces organizations to strengthen their network security policies.
(2) intrusion detection technology. Intrusion detection is the combination of firewalls (including signs of attacks on several key points in the security audit and monitoring of computer systems ). It includes system intrusion and internal unauthorized intrusion. It is a technology used to detect violations of security policies in computer networks. Intrusion detection technology has certain intelligent functions in identification. It detects networks and can extract and summarize intrusion features to help the system deal with network attacks, recognition and response, provides internal and external attack logs, which expands the security management capabilities of system network administrators. Although the human intrusion detection technology will promptly report the monitoring and attacks, the hacker attack methods are diverse and changing, and the intrusion detection technology is also difficult to detect in use, therefore, false positives or false positives may occur.
Therefore, from the above analysis, we can see that the current network security technology uses passive defense methods, network defense technologies that take firewalls and intrusion detection systems as the main technology lags behind today's various complex and variable hacker attack technologies. This requires us to turn passive defense into active defense. The honeypot technology helps system network administrators understand hacker trends and attack methods by observing and recording hacker activities on the honeypot, as an active defense technology, these network security problems can be solved.
