It is more it security basics than ever for data breaches and cyber attacks to occur. The attacks are no longer limited to large corporations with resources and sophisticated information security practices, but small businesses and even online marketplace sites can fall victim. This can cost a company revenue and expose the organization to liability risks. In fact, many successful attacks are the result of momentary lapses in cyber security best practices or simply user error.

Authentication is a first step, and it should be designed to ensure the identity of users is known. This could be something as simple as requiring a password when logging in or more complex, such as requiring a two-factor authentication system or a virtual private network that masks the internet protocol address (IP) so it is not identifiable.

Authorization is a second step and validates the permissions that a user has on a specific resource or set of resources. A common mistake is to hide permissions and require authorization only when the action is explicitly allowed, but this can lead to dangerous situations such as allowing administrators to delete other users’ accounts. Instead, it is often better to deny actions by default unless they are explicitly allowed and only allow the most sensitive actions after authorization has been verified.

Finally, output encoding is an important step in validating input and ensuring that the data that is sent to a client is formatted correctly for consumption. This prevents malicious data from being transmitted to the client where it might be used for exploiting vulnerabilities or triggering faults in the application.
