what is HSTS protocol?what is HSTS protocol?

November 28, 2020November 28, 2020 | rajinforajinfo | 0 Comment | 11:56 pm

HSTS, or HTTP Strict Transport security header(Strict-Transport-Security) is set on your domain, a browser will do all requests to your site over https from then onwards. In case when a hacker is redirecting this user to a fake domain.com, the browser remembers to use SSL because of the HSTS, so requests the secure site.

Browser needs to visit your site first to see this header, this will be active only after the first visit.

Why HSTS?

You can set SSL certificate on your domain, anyone can still use your site over http. The simplest solution is to add a redirect to your site and forces it over SSL. But user is open to attacks when the hackers directs the request to a site pretending to be non secured domain.

Do you Need SSL(https) for the Website?Do you Need SSL(https) for the Website?

July 17, 2020July 17, 2020 | rajinforajinfo | 0 Comment | 10:20 pm

What happen’s if you don’t have the SSL?

  • If the SSL certificate gets flagged as invalid by the browser, the data exchanged between you and the website you’re trying to connect to will be transferred in cleartext. Potentially, any user credentials or other sensitive data communicated over the channel can be sniffed or stolen. It is always recommended not to proceed over an insecure connection.
  • The user’s visiting your website will lose trust due to a lack of perceivable credibility.
  • Some users might be convinced that you are hosting a malicious website and would choose to steer clear even after the issue gets fixed.
  • Adversely impacts business and brings down the reputation especially if you are not a known player experiencing a temporary technical glitch.

How to Get it freely?

If you have website which is using wordpress then you an use below plugin to get the free SSL certification and install it make the website from http to https. Click here to get it freely.

WordPress SSL pulgin

The intention behind having an SSL/TLS certificate was not just for authentication but also to establish the identity of the remote server with whom the client browser communicates.

SSL /TLS protocol to ensure that data travels securely over the wire. Encrypting data in transit helps to prevent any malicious user from sniffing the network to steal sensitive information like passwords, credit card details, etc.

SSL or Secure Sockets Layer and TLS (Transport Layer Security) are cryptographic protocols designed to provide a secure communication channel between clients and servers over the internet. TLS is the relatively newer version when compared to SSL, SSL is the older encryption protocol.

New Law Passed Jallikattu WinsNew Law Passed Jallikattu Wins

Young Indians Saving Jallikattu

Young Indians Saving Jallikattu

The much awaited the Law for Jallikattu Was Passed. This is the huge victory for students #StudentsPower. Proud Movement for all. Unity wins. Jallikattus are big events that draw people in thousands. They generate a lot of consumption around them which is significant for the rural poor.

Why Jallikattu?

Supporters of native breeds argue that foreign breeds might not be a better option in the long run. Native breeds require less expensive maintenance and are less vulnerable to diseases and viruses. Jersey cows also require more grazing pastures. In the long run, native breeds are a better economic option. And Jallikattu is one big way people keep on rearing native cattle.

Artificial insemination, where semen from one bull can impregnate scores of cows, is criticized because it is believed to destroy the genetic diversity of cattle. It makes cattle more vulnerable to viruses and diseases. The supporters of native breeds argue that this has led to foreign companies creating monopoly on semen.

The low-yield milk of native cows can generate a huge demand as increasingly people perceive it to be more nutritious.
