# SQLQueryShield
|
20 |
-
|
21 |
-
## Model Description
|
22 |
-
|
23 |
-
SQLQueryShield is a vulnerable SQL query detection model. It classifies SQL queries as either vulnerable (e.g., prone to SQL injection or unsafe execution) or benign (safe to execute).
|
24 |
-
|
25 |
-
The checkpoint included in this repository is based on [microsoft/codebert-base](https://huggingface.co/microsoft/codebert-base) and further finetuned on [SQLShield](https://huggingface.co/datasets/salmane11/SQLShield), a dataset dedicated to text-to-SQL vulnerability detection composed of vulnerable and safe NLQs and their related SQL queries.
|
26 |
-
|
27 |
-
|
28 |
-
## Finetuning Procedure
|
29 |
-
The model was fine-tuned using the Hugging Face Transformers library. The following steps were used:
|
30 |
-
|
31 |
-
1. Dataset: SSQLShield, only the SQL queries from the (NLQ, SQL) pairs were used for training.
|
32 |
-
|
33 |
-
2. Preprocessing:
|
34 |
-
|
35 |
-
- Input Format: Raw SQL query strings.
|
36 |
-
|
37 |
-
- Tokenization: Tokenized using microsoft/codebert-base.
|
38 |
-
|
39 |
-
- Max Length: 128 tokens.
|
40 |
-
|
41 |
-
- Padding and truncation applied.
|
42 |
-
|
43 |
-
## Intended Use and Limitations
|
44 |
-
|
45 |
-
SQLQueryShield is intended for use as a post-generation filter or analysis tool in any system that executes or generates SQL queries. Its main role is to detect whether a SQL query is potentially harmful due to vulnerability patterns such as SQL injection, improper string concatenation, or unsafe expressions.
|
46 |
-
|
47 |
-
Ideal use cases:
|
48 |
-
|
49 |
-
- Filtering SQL queries in Text-to-SQL applications
|
50 |
-
|
51 |
-
- Post-processing or validating user-generated SQL before execution
|
52 |

|
53 |
