Website server hacker protection software

NET then it's worth using membership providers as they are very configurable, provide inbuilt website security and include readymade controls for login and password reset. 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.

If you have a file upload form then you need to treat all files with great suspicion. If you are allowing users to upload images, you cannot rely on the file extension or the mime type to verify that the file is an image as these can easily be faked.

Even opening the file and reading the header, or using functions to check the image size are not foolproof. Most images formats allow storing a comment section that could contain PHP code that could be executed by the server. So what can you do to prevent this? Ultimately you want to stop users from being able to execute any file they upload. By default web servers won't attempt to execute files with image extensions, but don't rely solely on checking the file extension as a file with the name image.

Some options are to rename the file on upload to ensure the correct file extension, or to change the file permissions, for example, chmod so it can't be executed. Ultimately, the recommended solution is to prevent direct access to uploaded files altogether. This way, any files uploaded to your website are stored in a folder outside of the webroot or in the database as a blob. If your files are not directly accessible you will need to create a script to fetch the files from the private folder or an HTTP handler in.

NET and deliver them to the browser. Image tags support an src attribute that is not a direct URL to an image, so your src attribute can point to your file delivery script providing you set the correct content type in the HTTP header. For example:. Most hosting providers deal with the server configuration for you, but if you are hosting your website on your own server then there are few things you will want to check.

Ensure you have a firewall setup, and are blocking all non essential ports. If possible setting up a DMZ Demilitarised Zone only allowing access to port 80 and from the outside world. Although this might not be possible if you don't have access to your server from an internal network as you would need to open up ports to allow uploading files and to remotely log in to your server over SSH or RDP.

If possible have your database running on a different server to that of your web server. Doing this means the database server cannot be accessed directly from the outside world, only your web server can access it, minimising the risk of your data being exposed.

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. If you have anything that your users might want private, it's highly advisable to use only HTTPS to deliver it. That of course means credit card and login pages and the URLs they submit to but typically far more of your site too. A login form will often set a cookie for example, which is sent with every other request to your site that a logged-in user makes, and is used to authenticate those requests.

An attacker stealing this would be able to perfectly imitate a user and take over their login session. That's no longer as tricky or expensive as it once was. Let's Encrypt provides totally free and automated certificates, which you'll need to enable HTTPS, and there are existing community tools available for a wide range of common platforms and frameworks to automatically set this up for you.
