Security+ Key Point
If you’re planning to take the Security+ exam, you might like to remember this key point.
The lack of input validation is one of the most common security issues on web-based applications. Input validation verifies the validity of inputted data before using it, and server-side validation is more secure than client-side validation. Input validation protects against many attacks, such as buffer overflow, SQL injection, command injection, and cross- site scripting attacks.
This is one of the Remember This blocks from the CompTIA Security+: Get Certified Get Ahead: SY0-501 Study Guide. As a study habit, I encourage readers to repeat these key points to themselves as often as possible. The more you repeat the information, the more likely you are to remember it when you take the exam.
The CompTIA Security+: Get Certified Get Ahead: SY0-501 Study Guide provides additional information needed to fully understand this key point.
