Website Security Tips
Hosting from trusted Source
Security of the site can be more reliable when it is hosted by a very trusted source. The reason why it is essential to have your website hosted from a trusted hosting service provider is that they have the right mechanism to control or restrict any malicious intruders from entering the site and damaging it or accessing data that is stored in the site.
Enabling the firewall would prevent unauthorized access to the website from a private computer network connected via the intranet. The firewall can be implemented as software or hardware that can selectively identify and block any incoming information as per the filters in it. Thus, blocking any malware or malicious software that can harm the website.
SSL certificate does not make the website secure, but it secures the information that flows through the website. This is especially applicable to the website that has user sensitive data like financial data or identifies specific data like social security numbers. The SSL certificate will encrypt any information that is fed into the website. In case the website is hacked, the information remains safe as the data cannot be decrypted without the encryption key.
This is another factor that can help to make a website more secure. It is important to ascertain the type of access that is permissible to a user, whether it is read and write access whereby the user can make changes to the contents of the website or read-only access whereby the user cannot add any data other than reading it. File permission is a crucial aspect which makes a website secure. Defining permissions on file extensions on the site helps in securing the content available on the site to a certain extent.
Always keep a backup
A backup storage of data is vital to overcoming any instances where the website may crash and lead to the loss of important information. Sometimes it may happen that due to virus entering the website, it crashes, and all the information is lost. Keeping a backup of the information will help in retrieving the data easily. Files can also be configured using. ngix files or .config files where specific policies can be added that helps in improving the overall security of the website.
Another way by which we can make the information on our website security is by encrypting access to some of the content available on the site which is very safe and essential from a website point of view, and the general visitor does not have access to. Information such as Passwords and Bank Account numbers are the ones who should be encrypted in such a way so that the general visitors are not able to access it.
Usage of parametrized query
There are attacks which occur on sites because of SQL injection when an attacker uses a URL to manipulate a place. This can be prevented by always using Parametrized queries which are easy to implement in most languages.
Cross-check the information shared
While giving error information to users, you need to make sure that accidently you are not sharing the secret information. It is always advisable not to provide exception details so that SQL injection can catch them and decipher what it means. Also, proper validation is required which should be done on the browser as well as the server side to make the website secure as these can be bypassed which could lead to malicious script affecting the website.
Customize your site
To make your website more secure it is essential that a customized admin page is created so that the intruder is unable to access the website admin page because that is where most of the critical information is there.
Choice of passwords
An essential aspect which adds to website security is through the protection of a password. The password that is chosen for a website should be strong enough so that nobody can decipher it. Security algorithms help a great deal in securing your passwords and making it a hard nut to crack, so if you have a website, then it should have inbuilt website security and readymade login credentials for password setting and reset, be extra careful. Also, one needs to make sure that during file uploads, it is seen that specific permissions have been incorporated in the file so that unknown person cannot decipher it.
Avoid multiple users
Another important factor to investigate is that does your website have numerous user logins? If it does, then one needs to make sure that the admin knows each user and that every user is assigned specific permissions to access a website.
Usage of HTTP2
You should use HTTP2. HTTP2 enables header compression. It will smaller the requests instead of sending full header every time under HTTP2.
Always Update CMS
There are many web applications which are easy to install like Joomla, WordPress, Magento etc. These Applications are very user-friendly and would automatically remind the user about the next update it is coming up with and the process to keep it updated is quite easy. So always update your application to latest version to avoid hacking through loopholes of previous version.
Hence, regular monitoring of the website especially if you have a payment gateway is imperative. You need to make sure that you have a security log data to meet Payment Card Industry Data security standard.
