With the rise in cyberattacks and with greater security risks, there needs to be a complex security intact to drive away the possible threats from accessing personal and sensitive information. Encoding the information transmitted from the browser to the server and vise versa can be the right solution to stay away from hacker’s interference. SSL/TLS encryption is required to encode the business and customer data . Internet Giants – Google, Microsoft and Facebook are focusing in implementing SSL/TLS encryption. Implementing SSL certificates would work out expensive and complex. Hence you will need to know the following fundamentals of SSL.
What is SSL/TLS?
SSL or Secure Socket layer is a cryptographic protocol that was first developed by Netscape in 1990s to deliver website authenticity by ensuring that the information passed through the website is safe and secure by converting the plaintext to unreadable coding language. The SSL protocol establishes encryption with a pair of keys public and private keys. The website encrypted with an SSL shows an https symbol with a padlock visible in the URL of the browser.
Why SSL is important?
The HTTP laden browsers are prone to vulnerable attacks. The data that are passed over the website can be interfered by hackers and it can be exploited to tamper and conduct fraudulent attacks and identity theft. Banks, financial and insurance companies that are liable to protect customer data implement SSL/TLS encryption making the information unavailable for the hackers to illegal access. However there are small websites that are yet to implement the use of SSL.
How hard it is to set up an SSL Certificate?
SSL implementation on a website is a bit tricky. Certificate Authorities provide SSL certificates to businesses to authenticate their websites. CAs deliver different types of SSL certificates to match each of the business requirements. The business entity is validated by the CA to prove that the business is legitimate. The validation process varies as per the type of SSL Certificate. SSL Certificates are bound to expire and it is critical for the IT administrator of the business entity to keep track of it and renew the same prior expiry to avoid inconsistency in the encryption process.
SSL and its Weaknesses?
There has been attacks that had compromised SSL/TLS connections already. Heartbleed is one such vulnerability that was identified in Open SSL – a most popular SSL application. Certificate Authorities have also been vulnerable to attack with hackers generating fake SSL certificates for phishing purposes. There are over 600 CAs known to deliver SSL certificates out of which Comodo and Verisign are the best.
Solution to overcome problems?
Securing the private SSL/TLS is probably the most vital criteria which is made plausible by hardware security units to protect and control the digital keys.
