(Newswire.net — November 6, 2015) — Security is highly important for absolutely any website that exists online, ranging from the personal blog to the international businesses. The problem is that there are some visitors that will not have the best interests in mind. Sites that have a poor security will always end up hacked.
Security vulnerabilities are sometimes the result of sub-standard practices with web development.
According to the pros at Sydney web developers you consider the following when designing a well secured website:
Minimizing User Inputs
A user input is a great access point for the dishonest hacker. We can see it as a gate that is open and that can be used for people to put in data into a site. In the event that you are not careful, hackers will be able to easily destroy information. There are even cases in which complete website control can be gained. Minimizing user input is a way to reduce the number of access points that a hacker can use. Only use user data in the event that it is absolutely necessary.
The Whitelisting Approach
When using user data, make sure to whitelist just some input types! Value lists have to be created and added to a whitelist feature. Before user input is processed, the system is to analyze if input present in a whitelist is present. If not, the next step is not taken. As an example, if first name is seen as necessary input, whitelist only letters. Numerals would not be normal to be used.
Try To Avoid Using GET Requests
This is definitely something that is important. A GET result is really easy to be error prone. This is due to the fact that parameters are going to be clearly visible in the browser’s URL. You should be careful and avoid using this function even when dealing with information that is not sensitive. It is important to do this because you want to avoid various threads like SQL injection. The POST request is definitely much better.
Sanitizing Parameters And Inputs
User inputs and URL parameters are dangerous in the event that they are not properly processed. This does include them being sanitized. URL parameters and user inputs should just be used in the event that there is no other opportunity. Sanitize data by using that whitelist method that was mentioned above. At the same time, do put a limit on how many user inputs and the parameters length. You can easily find information about how to do this on the internet.
Every Form Should Use Just One Token
Every single form has to use a single token. Language specific functions can easily generate unique tokens and this will vary based on the programming language that is used. When the token is generated, it has to be stored inside the use session and the form has to check if requests come from the form that it should. If not, the query would be rejected.
