Features that provide Web security when browsing online
When browsing online it is important to know the features that provide Web security that we stay safe and protect ourselves from threats that exist online. As such there are protection mechanisms which provide robust internet security which enables this protection.
Authentication
Authentication is a process of verification of the identity of a user who logs into a computer system or web application through a user and password credentials. It is a measure of protection of our data that guarantees the integrity of the same protecting them from theft and viruses. It is also a way to identify the data that belong to us from an internet platform or computer system. Currently it is spreading among the most well-known platforms such as Facebook, Google, among others, a two-step authentication measure that incorporates the previous security and a verification system that sends some digits to the cell phone that must be entered in the access.

Authentication Type |
Explanation – What it means? |
|
Anonymous logon |
This is where no username or password is required. Instead authentication is handles automatically by the browser and server. |
|
Basic authentication |
A username and password is required. This is where within a webpage a user will be prompted to type in their username and password in order to gain access. Once these credentials are verified the information is sent across the internet as plain text. |
|
Secure authentication |
A username and password is required. This differs from basic authentication as the information is encrypted before it is sent across the internet. Therefore if anyone intercepts it, it will be rendered useless as the information is encrypted. |
Digital certificate
A digital certificate will provide identification information (similar to a passport), is exceptionally difficult to forge and can be verified because it was issued by a trusted agency containing the name of the certificate holder, a unique serial number, expiration dates, a copy of the public key of the certificate holder and the digital signature of the authority that issued the certificate. These certificates can guarantee the security of a website through the implementation of SSL (Secure Socket Layer) and for this it is essential to have a digital certificate and install it on our website. They can also be used in corporate VPN connections, where only authorized devices with correctly configured certificates can access their business connections. In some companies, employees must encrypt and digitally sign email communications sent from their devices to ensure the privacy of sensitive information, demonstrate the origin of the message and mitigate phishing attacks.
Encryption
It is a security measure that is used to store or transfer sensitive information that should not be accessible to third parties. This is done by encryption algorithms such as AES, Cesar or MD5, so that it can not be used or read, even when they are intercepted. These measures can be adopted to protect hard drives and external memories that contain confidential information, encryption is also used to send messages and emails. It is used in the encryption of Wi-Fi connections and anonymous browsing or it can be used to encrypt the information of a database through the user’s own password.
Firewall
A firewall is a hardware device or software that allows managing and filtering all incoming and outgoing traffic between 2 networks or computers of the same network. It allows that they can only access the data.
The function of a firewall is to protect individual computers or servers from possible attacks of denial of services or unwanted access by intruders that can steal confidential data, lose valuable information or even deny services in our network. Setting up a firewall on our computer is a way of preserving our security and privacy to protect our home or business network and keep the stored information safe.
