Intranet SecurityFor enterprises, the problem should start from four levels and take into account the internal network security of the enterprise comprehensively. In terms of it o M, the security of user behavior should be determined. Finally, when users pass layer-by-layer security checks, in addition, enterprises also need to check the security of their infrastructure configurations to ensure boarding security. In response to the above problems, ac
1. Overview of Intranet Security
After the 21st century, with the rapid increase of information technology in China, the Intranet Information security has received more and more attention. In just a few years, Intranet security products and vendors have emerged. However, it is worrying that although many products and vendors provide services with the concept of
to ensure that in the complex network environment and work environment, as well as complex conditions can be very good work. It mainly determines whether it includes data leakage prevention, Internet behavior management, data use and application behavior audit, etc. (2) Stability: The product can operate stably in large data environment and even extreme environment, there is no single point of failure. And, need to ensure that its processing capacity (throughput) can cope with the pressure of e
enhanced, it also monitors network traffic transmitted in the Intranet, confirms whether data access complies with permission regulations, and handles changes to hardware and software environments.
Moreover, with the advancement of information security awareness, enterprises' focus is no longer limited to monitoring and management of information nodes, and more factors such as application efficiency and ma
affected global network operations and even the economy, these worms exploit the Program vulnerability in the operating system or application. At the same time, exploiting vulnerabilities has become one of the most common methods for hackers. Attackers first discover vulnerabilities through scanning tools and then use corresponding attack tools to launch attacks. This attack mode is simple and extremely harmful. The fundamental way to eliminate vulnerabilities is to install
BT Operation Principle Analysis and Intranet speed-up method (transfer)
Because Intranet users cannot provide an external port, they cannot act as servers. however, when using BT, we found that it could allow Intranet users to send messages. As a programmer, we couldn't help downloading its source code for analysis (to see it, I also specifically wrote Python :})
personnel security standards. If it is implemented in the regulations, it will be very meticulous, such as the security management of in-service personnel and the security management of resigned personnel.
In addition, people use the tool. For security tool products), and the use of daily office software, because each person's quality is different, the use of these tools, security awareness is different. "
It can be seen that the addition of human fa

After a long wait for virus detection and removal, several new viruses have been detected on the server, but unfortunately these viruses have almost nothing to do with the failure to access the Internet over the Intranet, because after these viruses are cleared, the Intranet
Intranet Security Status Quo Analysis
The theory of Intranet security is relative to the traditional network security. In the traditional network security threat model, it is assumed that all the personnel and devices in the Intranet are secure and trusted, while the external network is insecure. Based on this assumption, Internet security solutions such as anti-
Almost all enterprises have paid more attention to network security. They have successively purchased firewalls and other devices to block security factors from the Internet. However, Intranet attacks and intrusions are still rampant. Facts have proved that the company's internal insecurity is far more terrible than the external harm.
Most enterprises pay attention to improving the border security of enterprise networks, but do not mention their inves
Most enterprises pay attention to improving the border security of enterprise networks, but do not mention their investment in this area, but the core intranet of most enterprise networks is still very fragile. Enterprises have also implemented corresponding protection measures for internal networks, such as installing network firewalls and intrusion detection software that may easily reach tens of thousand

Data shows that manufacturing enterprises are also faced with problems such as data leakage, lack of confidentiality, and poor monitoring. How can we select a suitable Intran

In addition to increasing security patches, we also need to establish a monitoring system for the system and establish and implement effective user passwords and access control systems.
