A website vulnerability is any website flow which can be traced and exploited by a hacker. In spite of numerous security systems available in the contemporary period, the hackers anyhow manage to explore and find security breaches and hacking vulnerability in order to attack websites. The moment hackers succeed in hacking the website, they gain access to the admin panel and control the commands and can display anything they wish which may be potentially harmful to your reputation.
Eventually, all your data and information, as well as the information of your clients and customers, are now at the hands of the hackers and they can ultimately use them as they wish and for their malicious benefits. The most dangerous thing the hackers can do is to corrupt or delete all your database and website files from your website. In this context, everybody who has a website should consider all possible security threats while developing the website, and make sure that all essential preventive measures are implemented.
The SQL injection is a type of code injection attack which is normally used by the hackers through inserting code in the computer program. Since the database of the website has all the data and information of the clients and customers, the hackers try to access the database of the website by using SQL injection. The hacker first finds an input to incorporate SQL query and then inserts malicious play-load that is already incorporated in the query and eventually executed through the server. Once this is done, the hacker can read, create, and alter or even can delete any records that are maintained and applied in the database. The websites which have improper user input verification, as well as validation, are vulnerable to SQL injection. Therefore, the inputs provided by the user should always be verified and validated to protect your website from SQL injection.
Similarly, there are other numerous vulnerabilities which are normally traced by the hackers such as broken authentication and session management, XSS or cross-site scripting, insecure direct object reference, wrong security configuration, CSRF or cross-site request forgery, remote code execution, username enumeration etc. Some of the primary, as well as essential and important measures which can very effectively save the website from potential hackers, are never to visit any other websites when you are logged into your website or some of your sensitive sites such as your bank pages etc. In addition to this, you should always logout your website once your job is completed, and should never save login credentials.
