IDC Review Network (idcps.com) reported on August 04: according to the sampling monitoring results of CNCERT and the data released by the National Information Security vulnerability sharing platform (CNVD), during the fourth week of July (from 2015-07-20 to 2015-07-26), the overall evaluation of China's Internet network security index was good.

Next, please pay attention to the Internet network security situation in China from July 20 to July 26 with IDC Review Network:

(figure 1) basic situation chart of network security in the fourth week of July

According to figure 1, in the fourth week of July, the overall evaluation of China's Internet network security index is good. Among them, the number of hosts infected with the virus in China was 518000, down 25.3% compared with last week; the total number of tampered websites in China was 2652, a decrease of 30.2% from the previous month, of which the number of government websites dropped to 65

In addition, the total number of backdoor websites implanted in China reached 2892, a decrease of 34.6% compared with last week, of which the number of government websites decreased by 30.1%; the number of counterfeit pages aimed at domestic websites increased by 1.1% month-on-month to 4919

In addition, the number of new information security vulnerabilities was 191, a decrease of 16.6% from last week. Among them, the number of high-risk vulnerabilities decreased by 25.2% month-on-month to 77.

As shown in figure 2, the number of hosts infected with network viruses this week is about 518000, a decrease of 25.3% compared with last week. Among them, about 462000 hosts are controlled by * * or zombie programs, a decrease of 22.8% compared with the previous month; the number of hosts infected with conficker worms has decreased to 56000, a decrease of 41.3%.

The IDC Review Network learned through figure 3 that there were 9 new network virus names this week, 6 fewer than last week, 0 new network virus families and 2 less than the previous week.

(figure 4) Distribution of domain name registration at Fangma site at home and abroad

Take a closer look at figure 4 and note that the proportion of domain name registration in the territory of the Fangma site this week is as high as 61.6%, still in the first place, an increase of 9.9% compared with the previous month. In addition, the proportion of overseas and unknown territories ranked second and third, and the proportion shrank one after another, accounting for 37.7% and 0.6%, respectively.

(figure 5) the top-level domain names of 159 release sites

Looking at figure 5, we can see that the top-level domain names of the 159 Fangma sites this week are as follows: .com accounts for 86.2%. CN accounts for 7.5%. Net accounts for 3.1%. Info accounts for 1.3%. CC, .ORG and .HK all account for 0.6%. Compared with last week, the ranking has changed. Among them, .CN and .NET rank interchangeably.

II. Website security

(figure 6) Distribution of tampered websites by type in China

According to figure 6, in terms of network security, the most easily tampered websites in China are still .com websites, accounting for 75.4%, up 1.4% from the previous month. Net ranks behind, with the share falling to 6.3%. Followed by 2.5% of the .gov, 2.1% of the ORG, 0.1% of the .EDU, the ring ratio increased.

(figure 7) the websites implanted into the backdoor in China are distributed by type.

Observing figure 7 IDC Review Network, it is learned that the websites implanted into the backdoor in China are distributed by type, and the top six are .com, .ORG, .NET, .GOV, .EDU and .biz. Among them, .ORG accounted for 7.4%, a month-on-month increase of 5%, so its ranking rose from the fourth last week to the second. As a result, the rankings of .NET and .gov fell by 1 place to 3 and 4 respectively. The rest of the rankings remain the same.

III. Important loopholes

(figure 8) Information security vulnerability chart

From figure 8, we can see that a total of 191 new information security vulnerabilities were added this week. Among them, the largest number of medium-risk vulnerabilities was 89, down 25.8% from the previous month, followed by 77 high-risk vulnerabilities, down 25.2% from the previous month, and the lowest number of low-risk vulnerabilities, up 316.7% from the previous month.

(figure 9) vulnerabilities included this week are distributed by type of impact object.

As shown in figure 9, the top six lists of vulnerabilities are distributed according to the type of affected objects this week, which has changed compared with last week. The ranking of operating system vulnerabilities and database vulnerabilities rose to 2nd and 3rd, accounting for 22.5% and 12.6%, respectively. In addition, the ranking of application vulnerabilities remained unchanged, ranking first, with the proportion shrinking to 57.1%. The rest of the rankings declined, with WEB application vulnerabilities falling from No. 2 to No. 5, down 14.4% from the previous month to 3.1%.

To sum up, during the fourth week of July, the overall evaluation of China's Internet network security index is good. No serious network security incidents have been found.
