What type of vulnerability scan would be most likely to detect a SQL injection issue
Snort is an open-source, free and lightweight network intrusion detection system (NIDS) software for Linux and Windows to detect emerging threats. Snort can be used to detect SQL injection attacks. Show

Vital Information on SQL InjectionsVulnerabilities in SQL Injection is a high risk vulnerability that is one of the most frequently found on networks around the world. This issue has been around since at least 1990 but has proven either difficult to detect, difficult to resolve or prone to being overlooked entirely.
How to Fix SQL Injection VulnerabillitiesUse of Vulnerability Management tools, like AVDS, are standard practice for the discovery of this vulnerability. The primary failure of VA in finding this vulnerability is related to setting the proper scope and frequency of network scans. It is vital that the broadest range of hosts (active IPs) possible are scanned and that scanning is done frequently. We recommend weekly. Your existing scanning solution or set of test tools should make this not just possible, but easy and affordable. If that is not the case, please consider AVDS. Penetration Testing (pentest) for SQL InjectionThe Vulnerabilities in SQL Injection is prone to false positive reports by most vulnerability assessment solutions. AVDS is alone in using behavior based testing that eliminates this issue. For all other VA tools security consultants will recommend confirmation by direct observation. In any case penetration testing tools for discovery of Vulnerabilities in SQL Injection produces the highest discovery accuracy rate, but the infrequency of this expensive form of testing degrades its value. The ideal would be to have pentesting accuracy and the frequency and scope possibilities of VA solutions, and this is accomplished only by AVDS. Security Updates on Vulnerabilities in SQL InjectionGiven that this is one of the most frequently found vulnerabilities, there is ample information regarding mitigation online and very good reason to get it fixed. Hackers are also aware that this is a frequently found vulnerability and so its discovery and repair is that much more important. It is so well known and common that any network that has it present and unmitigated indicates “low hanging fruit” to attackers. Confirming the Presence of Vulnerabilities in SQL InjectionAVDS is currently testing for and finding this vulnerability with zero false positives. If your current set of tools is indicating that it is present but you think it is probably a false positive, please contact us for a demonstration of AVDS. False positive/negativesThe secret killer of VA solution value is the false positive. There was an industry wide race to find the most vulnerabilities, including Vulnerabilities in SQL Injection ,and this resulted in benefit to poorly written tests that beef up scan reports by adding a high percentage of uncertainty. This may have sold a lot of systems some years ago, but it also stuck almost all VA solutions with deliberately inaccurate reporting that adds time to repairs that no administrator can afford. Beyond Security did not participate in this race to mutually assured destruction of the industry and to this day produces the most accurate and actionable reports available. Patching/Repairing this VulnerabilityVulnerabilities in SQL Injection is a high risk vulnerability that is also high frequency and high visibility. This is the most severe combination of security factors that exists and it is extremely important to find it on your network and fix it as soon as possible. What is the most common SQL vulnerability?For instance, in the case of a financial application, an attacker can use SQL injection to change account balances. Even worse, attackers can gain administrative rights to an application database. The most common risk of an SQL injection attack is the theft of user data.
How are SQL injection vulnerabilities detected?Blind SQL injection is used where a result or message can't be seen by the attacker. Instead, the technique relies on detecting either a delay, or a change in the HTTP response, to distinguish between a query resolving to TRUE or FALSE .
Which application can be used to detect SQL injections?SQLMap is the open source SQL injection tool and most popular among all SQL injection tools available. This tool makes it easy to exploit the SQL injection vulnerability of a web application and take over the database server.
Which type of vulnerability is demonstrated by an SQL injection?SQL injection (SQLi) is a web security vulnerability that allows an attacker to interfere with the queries that an application makes to its database. It generally allows an attacker to view data that they are not normally able to retrieve.
