Security O & M is not feasible only by single item prevention

Diverse security threats and diversified Protection

With the development of IT technology, the IT environment of enterprises becomes more and more complex, and security threats become more diverse and serious. Many enterprises try to maintain a secure IT environment by deploying the best single product security solution, but this also makes the IT environment more complex. In this case, enterprises need a security management platform solution to help them implement real-time monitoring and respond quickly.

Why does Internet security fail?

Firewall is the most common tool to ensure network security for a long time and an important measure to protect enterprise network security. Firewall technology is undoubtedly the best choice for enterprises. A firewall is a combination of components set between different networks or network security domains. It monitors, limits, and modifies the data streams that span the firewall, and shields internal network information as much as possible.

To ensure the security of Web websites, you must first consider the security of Web servers. In general, Web websites built on Unix systems have better security, followed by Linux systems. Enterprises should first consider deploying the Web server architecture on the Unix System Platform under economic conditions. System patches must be installed in a timely manner regardless of the system. In addition, the security of Web server software should be considered.

A Virtual Private Network is an extension of an enterprise's intranet. VPC helps remote users, branches, and business partners establish trusted and secure connections with the company's intranet. A virtual private network can be accessed through the global Internet of mobile users, or through a virtual private line for secure communication between enterprise websites to economically and effectively connect to the relevant security extranet virtual private network.

The Secure Mail Gateway can effectively protect the mail server from various forms of network attacks from the network layer to the application layer, it also provides Email users with functions such as Blocking spam, scanning and removing email viruses, and filtering email content. Using products based on content filtering, virus detection and prevention of Spam can greatly improve the prevention accuracy.

These are the security products and policies widely used in enterprise Internet Security O & M management. They are mainly used to ensure the normal, secure, and stable operation of networks and services. However, at present, worms, viruses, Trojans, botnets, spam, and so on are rampant, and only security products and security policies are insufficient.

Unified solutions are required for Intranet Security

The internal information network is composed of a large number of terminals, servers and network devices. Any part of the security vulnerabilities may paralyze the entire network. This poses unprecedented challenges to the controllability and reliability of each component of the Intranet.

Traditional network security concerns the prevention of Internet attacks on the Intranet. Traditional firewalls, intrusion detection systems, and VPN are designed and considered based on this idea.

The Internet security threat model assumes that the internal network is safe and trustworthy, and all threats come from the external network. The approach is primarily through the Intranet and Internet border egress. The threat model of Intranet security assumes that any terminal, user, and network in the Intranet network is insecure and requires careful management of all the nodes and participants in the internal network. It can be seen that, compared with the internet security model, the Intranet security model requires a more comprehensive, objective, and strict security system and more fine-grained security control measures.

Internet security mainly prevents external intrusion or illegal external traffic access. It also focuses on technologies such as firewalls and intrusion detection. Intranet security management is much finer than Internet Security Management. In terms of technology, Intranet security usually uses reinforcement technology, such as setting access control and identity management.

Because the intranet information transmission usually uses broadcast technology, data packets are easily listened to and intercepted in the broadcast domain. Therefore, a manageable security switch is required, network segments and VLANs are used to physically or logically isolate network resources to enhance Intranet security. Important data must be backed up to maintain enterprise intranet security. It is essential to select well-functional and Flexible backup software.
Intranet anti-virus management must be fully integrated with the Internet. In addition to traditional manual detection and removal and file monitoring, the network layer and mail client must be monitored in real time. Because the Intranet is generally logically isolated from the Internet through the firewall, you can use measures such as NAT address translation and terminal pc ip/MAC Address binding to protect Intranet security. In addition, the use of online behavior management system software can achieve Website access restrictions, web content filtering, instant tool filtering, IP Address binding, IP address access control and other functions, to ensure the normal operation of key enterprise applications.

Therefore, an enterprise intranet security O & M management system must be established, including identity authentication, authorization management, data confidentiality, and monitoring and auditing. These factors must be closely integrated and interconnected.

Security O & M should also be platform-based

With the increasing number of enterprise network applications and scale, network management becomes more and more heavy, and network faults also occur frequently: network operation is not understood, and the system becomes a bottleneck; when the system becomes faulty, it cannot be detected and diagnosed in time. There are many network devices and complicated configuration management. network security is threatened ...... Currently, many enterprises are considering purchasing network management software to enhance network management and optimize existing network performance. Network management software systems have become an indispensable IT component for enterprises.

At present, network management system developers develop corresponding management software for different management contents, including the network management system (NMS), Application Performance Management (APM), and Desktop Management (DMI), employee behavior management (EAM), security management, etc. Asset Management and fault management in traditional network management models are still popular. More and more businesses will enter the monitoring scope of network management, and the segmentation of business monitoring will become the focus of improving the network management system in the future. The security management platform is a sub-branch.

When enterprise network engineers face a large amount of network data, they need clear ideas, clear organization, and practical basis. Therefore, the security management platform has become their best choice. For example, the Broada security management platform provided by guangcommunication can centrally detect and respond to security threats, so that network engineers can obtain the latest security information, through powerful real-time troubleshooting and Security Threat Response Functions, you can view the security status view of enterprise IT systems, so as to sort out useful data, improve security management efficiency, and reduce IT total costs.
