本文主要是介绍Bandit：一款Python代码安全漏洞检测工具，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
工具介绍
Bandit这款工具可以用来搜索Python代码中常见的安全问题，在检测过程中，Bandit会对每一份Python代码文件进行处理，并构建AST，然后针对每一个AST节点运行相应的检测插件。完成安全扫描之后，Bandit会直接给用户生成检测报告。
工具安装
Bandit使用PyPI来进行分发，建议广大用户直接使用pip来安装Bandit。
创建虚拟环境（可选）：中国菜刀
virtualenv bandit-env安装Bandit：
pip install bandit
# Or if you're working with a Python 3 project
pip3 install bandit
运行Bandit：
bandit -r path/to/your/code用户还可以使用源码文件直接安装Bandit，先从PyPI下载原tarball，然后运行下列命令：
python setup.py install工具使用
节点树使用样例：
bandit -r ~/your_repos/projectexamples/目录遍历使用样例，显示三行内容，并只报告高危问题：
bandit examples/*.py -n 3 –lllBandit还能够结合配置参数一起运行，运行下列命令即可使用ShellInjection来对examples目录运行安全扫描：
bandit examples/*.py -p ShellInjectionBandit还支持使用标准输入模式来扫描指定行数的代码：
cat examples/imports.py | bandit –使用样例：
$bandit -h

--ignore-nosec do not skip lines with # nosec comments
-x EXCLUDED_PATHS, --exclude EXCLUDED_PATHS
comma-separated list ofpaths (glob patterns supported)
to exclude from scan(note that these are in addition
to the excluded pathsprovided in the config file)
-b BASELINE, --baseline BASELINE
path of a baselinereport to compare against (only
JSON-formatted filesare accepted)
--ini INI_PATH path to a .bandit file that suppliescommand line
arguments
--version show program's version number andexit
CUSTOMFORMATTING
-----------------
Availabletags:
{abspath}, {relpath}, {line}, {test_id},
{severity}, {msg}, {confidence}, {range}
Exampleusage:
Default template:
bandit -r examples/ --format custom--msg-template \
"{abspath}:{line}: {test_id}[bandit]:{severity}: {msg}"
Provides same output as:
bandit -r examples/ --format custom
Tags can also be formatted in python string.format()style:
bandit -r examples/ --format custom--msg-template \
"{relpath:20.20s}: {line:03}:{test_id:^8}: DEFECT: {msg:>20}"
See python documentation for moreinformation about formatting style:

基准线
Bandit允许用户指定需要进行比对的基线报告路径：奇热影视
bandit -b BASELINE这样可以帮助大家忽略某些已知问题，或者是那些你不认为是问题的“问题”。大家可以使用下列命令生成基线报告：
bandit -f json -o PATH_TO_OUTPUT_FILE版本控制整合
安装并使用pre-commit，将下列内容添加至代码库的.pre-commit-config.yaml文件中：
repos:
- repo: https://github.com/PyCQA/bandit
rev: '' # Update me!
hooks:
- id: bandit
然后运行pre-commit即可。
扩展Bandit
Bandit允许用户编写和注册扩展以实现自定义检测或格式化（Formatter）功能。Bandit可以从下列两个节点加载插件：
bandit.formatters
bandit.plugins
Formatter需要接收下列四种输入参数：
result_store:一个bandit.core.BanditResultStore实例
file_list:需要扫描检测的文件列表
scores:每个文件的扫描评分
excluded_files:列表中不需要扫描的文件
利用bandit.checks来对特定类型的AST节点进行检测扫描：
@bandit.checks('Call')
defprohibit_unsafe_deserialization(context):
if 'unsafe_load' incontext.call_function_name_qual:
return bandit.Issue(
severity=bandit.HIGH,
confidence=bandit.HIGH,
text="Unsafe deserializationdetected."
)
注册插件时Bandit给用户提供了两个选项：
1、 如果你直接使用了安装工具（setuptools），我们需要在setup调用中添加下列信息：
# Ifyou have an imaginary bson formatter in the bandit_bson module
# anda function called `formatter`.
entry_points={'bandit.formatters':['bson = bandit_bson:formatter']}
# Ora check for using mako templates in bandit_mako that
entry_points={'bandit.plugins':['mako = bandit_mako']}
2、 如果你使用的是pbr，你需要在setup.cfg文件中添加下列信息：
[entry_points]
bandit.formatters=
bson= bandit_bson:formatter
bandit.plugins=
mako = bandit_mako
