Ever wondered how an attacker is able to access other peoples’ data with their own computers? Hackers exploit using a structured query language (SQL) code which gives the computers new commands. The SQL statements control the database through a web application to bypass security measures. A malicious play load created by the attacker gives commands executed in the database. With vulnerable user inputs in the web applications, attackers are able to access, modify, and delete data and run some operating system commands in some cases.
SQL injections have proved an effective way of manipulating data layers despite the presence of intrusion detectors and firewalls installed. According to the 2011 data breach investigations report produced by Verizon Business, nearly 25% of all compromised record were accessed with the SQL injection systems (Walters, 2010). Once attackers gain control over the database, they have full access to data and the ability to attack other users within the database. Hackers are even able to act as the system administrators of the database servers.
Delegate your assignment to our experts and they will do the rest.
Evaluating the value of data that can be compromised helps to understand the impact of SQL injection attack. Most companies have had an affected public image that have resulted to profit losses in the events of vicious attacks. SQL injection attacks have been frequently experienced where customers” credit card numbers have been stolen. Other businesses have been robbed of their clients and fallen victim of the SQL injections. The Open Web Application Security Project (OWASP) lists SQL injection as the number one threat to web application security in their document (OWASP Top 10 2017). SQL injection attack therefore creates a great impact through compromised authentication and authorization of web pages.
