3.設計了訪問控制功能
? 我們設計了初步的訪問控制能力,其主要方式是非涉密人員看不到涉密文件,具體來說是非涉密人員根本就無法從前端頁面上看到涉密文件的任何信息,從名字到存儲路徑。簡而言之就是非涉密人員根本不知道涉密文件的存在。
? 我們目前的加密是對文件存儲路徑的加密,簡而言之就是數(shù)據(jù)庫里只放文件的存儲路徑,在我們的設計中,服務器應該存放在一間安全的機房里,用戶通過安全連接來訪問數(shù)據(jù)庫,得到所需公文的路徑,進而訪問公文。
4.在本地上安裝了項目所需環(huán)境,并進行了測試
(1)安裝依賴庫
pip3 install filetype
pip3 install django-sslserver
pip3 install gmssl
pip3 install secrets
(2)調(diào)整本地MySQL
? 我在部署的時候出現(xiàn)了這個問題:
Django.db.utils.OperationalError: (1045, "Access denied for user 'root'@'localhost' (using password...
? 經(jīng)過王上查閱資料,得知這是由于Mysql 8.0 的部分語法,密碼的加密方式發(fā)生了改變,在8.0 中的用戶密碼采用的是cha2 加密方法,Django 對這種加密的密碼進行編譯導致密碼設置錯誤。
? 解決方法如下:
mysql -u root -p
use mysql;
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'newpassword';
FLUSH PRIVILEGES;
修改密碼以后,重新執(zhí)行:
python manage.py runserver
(3)寫入加密測試代碼
