02. Watch out for SQL injection
SQL injection attacks are when an attacker uses a web form field or URL parameter to gain access to or manipulate your database. When you use standard Transact SQL it is easy to unknowingly insert rogue code into your query that could be used to change tables, get information and delete data. You can easily prevent this by always using parameterised queries, most web languages have this feature and it is easy to implement.
03. Protect against XSS attacks
Cross-site scripting (XSS) attacks inject malicious JavaScript into your pages, which then runs in the browsers of your users, and can change page content, or steal information to send back to the attacker. For example, if you show comments on a page without validation, then an attacker might submit comments containing script tags and JavaScript, which could run in every other user's browser and steal their login cookie, allowing the attack to take control of the account of every user who viewed the comment. You need to ensure that users cannot inject active JavaScript content into your pages.
04. Beware of error messages
Be careful with how much information you give away in your error messages. Provide only minimal errors to your users, to ensure they don't leak secrets present on your server (e.g. API keys or database passwords). Don't provide full exception details either, as these can make complex attacks like SQL injection far easier. Keep detailed errors in your server logs, and show users only the information they need.
05. Validate on both sides

Validation should always be done both on the browser and server side. The browser can catch simple failures like mandatory fields that are empty and when you enter text into a numbers only field. These can however be bypassed, and you should make sure you check for these validation and deeper validation server side as failing to do so could lead to malicious code or scripting code being inserted into the database or could cause undesirable results in your website.
06. Check your passwords
Everyone knows they should use complex passwords, but that doesn’t mean they always do. It is crucial to use strong passwords to your server and website admin area, but equally also important to insist on good password practices for your users to protect the security of their accounts.
07. Avoid file uploads
Allowing users to upload files to your website can be a big website security risk, even if it’s simply to change their avatar. The risk is that any file uploaded, however innocent it may look, could contain a script that when executed on your server, completely opens up your website.
08. Use HTTPSAdvertisement
HTTPS is a protocol used to provide security over the Internet. HTTPS guarantees that users are talking to the server they expect, and that nobody else can intercept or change the content they're seeing in transit.
