If a Website indicates me that I am protected by a secure connection, can I trust it ?
Not necessarily. A secure connection ensures only the identity of the website that you are visiting, and this on the basis of information provided by the certification organization. Also make sure that secure encrypted link is enabled. You must keep in mind to only give your personal information to sites or organizations known and who you trust. Before entering any information on a website, you should see the reputation it has on the internet, so simply search the name of the website on google and see what others have to say.
Now that you know this, you should also know more about recognizing a true "secured connection".
What is the meaning of the padlock located on the left/right side of the url page on some website ?
If you ever meet a lock on the bottom part of a page or located next to the URL bar, this means the connection is secure.The padlock indicates the implementation of SSL (security standard transfers, which can encrypt data, authenticate the server and message integrity) or TLS. To be sure that these pages are under the protection of SSL, just read the url of the site, it must start with https:// the s stands for secures it indicates that the presence of security is guaranteed.
What do the letters SSL found on some websites mean ?
If there are dangers on the net, there are also safety zones. SSL (Secure Sockets Layers) guarantee the existence of a secure data exchange. SSL is a security standard transfers, which encrypts data, to authenticate the server and message integrity. SSL is typically used by online stores through which many banking transactions are made. When data is transmitted, they enter a certain path, which makes this information invisible to any person other than the exchange destination. Thus, it is possible to give his credit card number or other confidential information with a security guarantee. Attention, SSL guarantees a security in data transfer but not a security from your PC (therefore information cards can be stolen if you are infected with a virus or keylogger). Note that in SSL there is no client authentication. This technology is being replaced by the TLS which is more secure.
Wait.. so the SSL doesn't guarantee a good security ?
SSL does not provide a sufficient level of security against piracy. 100% of online banks websites use SSL. SSL is certainly very secure but does not guard against unauthorized access using the login data (username and password). So there is still a need to generalize a reinforced authentication security.Nevertheless, It is important to have a recent version of your web browsers, so that they can handle this level of encryption.
