What is SSL?
SSL stands for Secure Sockets Layer, a standard security technology for creating encrypted links between web servers and browsers. This link ensures that all data passed between the web server and the browser remains private and complete. SSL is the industry standard, with millions of websites using SSL to protect online transactions with customers.
SSL allows secure transmission of confidential information such as social security numbers, credit card numbers or login credentials. Without SSL, the data sent between the client and the server will be sent in plain text – which makes it easy to intercept. Anyone who can hijack the data stream has unlimited access to plain text. With SSL, the data is encrypted – even if it is intercepted, it cannot be decrypted.
How to tell if a wbsite is SSL secured?
Check the SSL certificate
View the URL of the website. If it starts with “https” instead of “http”, it means that the site is protected with an SSL certificate (s stands for security). The SSL certificate protects all data as you pass it from the browser to the web server. To obtain an SSL certificate, the company must go through the verification process.
Look at the Domain
Cyber attackers sometimes create websites that mimic existing websites and try to trick people into buying or logging into their phishing websites. These sites usually look exactly like existing sites.
To avoid this type of attack, always check the domain name of your site. If you receive an email from a bank or other online provider, do not click on the link in the email. Type the domain in your browser to make sure you are connected to the website you plan to be.
