DNS system associated with DDoS attacks

Absrtact: August 7 google on its official blog announced that they will https into its search algorithm mechanism, the use of HTTPS security certification of the site will be Google to give more trust, which is conducive to the site in the Google search results ranking upgrade. But on August 7, Google on its official blog announced that they will https into its search algorithm mechanism, the use of HTTPS security certification site will be more trust by Google, which is conducive to the site in Google's search results ranking upgrade. But the current HTTPS's impact on Google's site rankings is very limited, but one of its hundreds of ranking factors is very weak. The HTTPS part of the algorithm adjustment will affect Google's global search volume of about 1% of the results.





will Google improve HTTPS's weight on the site rankings? This possibility exists because Google wants to give webmasters some time to adjust their websites, from HTTP to HTTPS. Future HTTPS security certification may be one of the most important factors affecting the ranking of websites.




Introduction to
HTTPS and its differences from HTTP


when it comes to HTTPS and SSL, let's say the difference between HTTP and them first. We are not unfamiliar with HTTP, that is, Hypertext Transfer Protocol (hypertext transmits Kyoto), the agreement between the browser and the World Wide Web server communication rules, is our usual Internet transmission data on the basis of the Protocol, has been very widely used. Most websites now use HTTP protocol. But HTTP has a certain flaw in security, that is, the lack of plaintext transmission and message integrity detection. This security flaw is easily exploited to obtain personal information, such as cell phones, identity information, credit card numbers, and so on. In particular, online transactions, payments, etc. have become very common.





It is against the security risks of HTTP, Netscape Netscape Company put forward HTTPS protocol to enhance the security of data transmission on the Internet. HTTPS adds an SSL (secure Sockets Layer) protocol that guarantees data traffic security between TCP and HTTP. This SSL-based HTTP Information Transfer Protocol is HTTPS (Hyper Text transmits Kyoto over Secure Socket Layer), which is abbreviated to HTTPS. SSL is now replaced by the new TLS (by Layer Security). HTTPS uses a different data port than HTTP, the former being 443 and 80.





Adoption/Conversion to HTTPS considerations


Google announced this algorithm adjusted, I believe there will be many webmaster to the existing Web site to HTTPS or for the new Web site to apply for HTTPS certification. So what are the issues to pay attention to?


1.SSL Security certification is divided into three kinds: Single Web site certification, multiple domain name certification, and contains the domain name of the Web site certification, choose which type of certification, according to their actual needs, different certification price charges are not the same.


2. To use the 2048-bit root certificate, this is Google recommended


3. If you are adding SSL authentication to an existing Web site, make sure that URLs that contain https are allowed to be indexed in robots.txt


4. To unify the URL criteria because https://www.****.com and http://www.***.com are two different pages for Google. Website URL conversion process to comply with Google's website relocation optimization Advice Guide.


Conclusion


HTTPS security certification has been trusted by Google, Google is also for its own web site all the use of HTTPS security certification, which has become a major trend in the present. The use of HTTPS security certification will depend on the industry and affordability of each site. The undeniable fact is that it is not possible for all sites to use HTTPS, even if the use of HTTPS security certification will not give the site a very significant ranking upgrade, because the final ranking depends on the content value of the site and trust. Through this Google algorithm adjustment, we have seen that Google has the ability, a decision may have a huge impact on the entire Internet. The future of HTTPS as a universal standard for Internet communication protocols is unknown. See!
