Intranet security requires you to know yourself and know that data leakage prevention is the key

This year's various data leakage events are numerous, highlighting the serious shortage of Enterprise Intranet security. When you constantly respond to external attacks and build a high wall for external security of the enterprise, have you ever wondered whether a small internal vulnerability may cause the collapse of the entire security line? You must be at ease, otherwise a small negligence may make all your security efforts at a loss.

Compared with Intranet security, viruses, Trojans, hackers, worms, spyware, and spam are mostly attacks with unclear targets, internal theft, malicious destruction, out-of-control permissions, security vulnerabilities, and other such attacks are targeted, causing greater harm.

After more than a decade of development, Intranet security has evolved from auditing to security protection for more platforms; from simple online behavior management products and asset management products to complex and comprehensive Intranet security management products. Despite this, Intranet security in the new era is still facing greater challenges. How can enterprises deploy an Intranet security defense system? Under cloud computing and mobile Internet Trends, what are the most important aspects of Intranet security? Recently, I have discussed with many people in the security industry. The following are some suggestions:

Know yourself and know yourself is the top priority

We cannot always talk about how important Intranet security is, but do not take practical actions. So what should enterprises do first in improving Intranet security?

Huang Kai, product director of Yixin technology, said that the first thing enterprises need to do is to understand themselves. As the saying goes, "Know Yourself And know yourself" cannot be defeated. To achieve Intranet security, you must understand the operation of enterprise information, so as to understand the data protection requirements, select appropriate products according to each specific requirement, and finally establish a complete Intranet security system.

Specifically, it is necessary to assess the information security status of an enterprise as a whole, use a unified platform for risk and security management, and detect internal problems, in this way, we can draw a clearer and more accurate picture of the current security situation of the entire enterprise, and adopt targeted protection measures to minimize the security risks of the enterprise. Another important point is that enterprises must implement "Visualization" of operations to monitor the security status of the entire information system at any time, so as to quickly respond and even predict potential risks, turn passive defense into active defense.

In the past, Intranet security was only simple monitoring and auditing. Now the management scope of Intranet security includes Information Security Protection Information Leakage Prevention DLP), network security control, host security check, Patch Management and Vulnerability Detection), behavior management desktop behavior audit, online behavior audit, External Device Control), system O & M Asset Management, software distribution, and system maintenance) these three aspects.

The above three aspects are indispensable to form a solid Intranet security system. Taking the IP-guard product of Yixin technology as an example, it initially only provides computer behavior monitoring within the enterprise. With the continuous development of Intranet security, according to the systematic overall defense concept, now it has provided a triple protection system. The first one is auditing, that is, knowing what is done; the second is control, that is, Preventing confidential information from being taken away; the third is encryption, that is to say, you are not afraid to take it away.

Data leakage prevention is the focus

Nowadays, cloud computing, virtualization, and mobile devices are no longer uncommon. What changes should Intranet security be made in the face of these new trends? What will be its core technology in the future?

Huang Kai believes that, even under the cloud computing trend, most enterprises will not store their most important information on the cloud. In this regard, the Intranet security of enterprises is not changing much. However, the general trend is to establish private clouds for enterprises. Therefore, Intranet security will focus on Private clouds. At the same time, the application of virtualization and mobile devices has made data flow wider. Therefore, in the future, the focus of Intranet security is data leakage prevention DLP ). Regardless of the platform, the protection of sensitive information will become one of the issues that enterprises must consider.

Therefore, in terms of technology, Sandbox technology, which is widely used for network access, will be applied to Intranet security. Its core is to isolate sensitive data from common data. In addition, behavior trend analysis and operation content analysis will become more common. The former provides timely warnings for possible illegal operations and provides personalized and rich report analysis. The latter includes keyword alarm and document content check.

In general, to achieve Intranet security, enterprises should first pay attention to Intranet security, and then control the circulation of internal information after analyzing their own security requirements, implement data protection. Think twice and proceed with caution. Intranet security will go further.
