Stay ahead of cyber threats with insights into SQL injection attacks. Learn prevention techniques and safeguard your database

1. SQL Injection
SQL Injection is a type of attack where a malicious user can manipulate
the data in a database by injecting unauthorized SQL code. The
consequences can be devastating and the risk to security is high.

2. Types of SQL Injection Attacks
1 In-band SQLi
The attacker uses the
same communication
channel to launch the
attack and retrieve data.
2 Blind/Inferential
SQLi
The attacker sends
requests to the server
with specific queries and
analyzes the response
to infer information.
3 Error-based SQLi
The attacker exploits
errors and generates
SQL queries that trigger
them.

3. Examples of SQL Injection Attacks
Target
The 2017 Equifax Data Breach
exploited an Apache Struts
vulnerability to inject malicious
code. The result: 146.6 million
Social Security numbers
stolen.
Potential
Instrumentalizing SQL Injection
attacks, PayPal, Ticketmaster,
and British Airways have all
suffered significant data
breaches in recent years.
Unforeseen
Cornell University discovered
that one of its web applications
was exposing all database
information, allowing anyone to
execute database queries and
alter data because of an SQL
Injection vulnerability.

4. Tools to Prevent SQL Injection Attacks
Prepared Statements
The simplest form of
preventing SQL Injection
attacks is through the use
of prepared statements.
Stored Procedures
Stored procedures, which
are implemented and
stored on the server side,
can prevent SQL Injection
attacks by encapsulating
database access in a
package that cannot be
modified by exploits.
Web Application
Firewalls
Web Application Firewalls
can prevent SQL Injection
attacks by filtering and
blocking malicious requests
before they reach the
server.

5. Best Practices to Avoid SQL Injection
Vulnerabilities
1
Input Validation
Validate and sanitize all user input before
processing and be sure to use parameterized
queries. Input validation can help stop several
types of attacks, including SQL Injection
attacks.
2
Use Least Privilege Principle
Limit permissions to execute stored
procedures. Use database roles and
permissions to limit who can execute them.
3
Audit Your Application and
Database
Auditing helps to identify security
vulnerabilities and prevent attacks. Monitor
your database and web application for
suspicious activity.

6. Conclusion
Impacts Everything
A successful SQL Injection attack can take down
entire systems and expose entire data sets.
Security is Key
Keeping your applications and systems up-to-
date with the latest patches is your best defense
against these vicious attacks.
