上午烤J。(~~照样迟到~~)

看了看第一题,发现就是map的板子,`max(0,52-mp.size());`,五分钟秒了。

第二题看上去是大模拟,敲了30min,样例没过!!!调了30min,样例过了,(注意这个细节)放在旁边拍着去了,感觉100pts。

第三题爆搜了15min,直接打表(然而电脑冒青烟了,换了一台键盘卡住的),还写错了,直接爆了。后不知找规律的好,写了俩特殊性质,估分60pts?

第四题神马思路都没有,注释了一个`I AK IOI`,没啥事干,吃了一巧克力,干掉极域,颓到考试结束。

咕260pts。

##### 谷

中午烤谷。外国语学校旁那家肉丝面贼好吃,上你谷接受神犇光环照耀。

##### S

第一题:$\texttt{不可以,总司令!}$喜提25pts。

### CSP (Content Security Policy) 2024 Updates and Information A Content Security Policy (CSP) is an added layer of protection that helps detect and mitigate certain types of attacks, including Cross-Site Scripting (XSS) and data injection attacks. In the context of evolving web technologies and increasing security threats, several updates are anticipated for CSP in 2024. #### Enhanced Reporting Mechanisms The reporting mechanisms within CSP will be enhanced to provide more detailed insights into policy violations. This includes improved support for `report-to` directives which allow developers to specify endpoints where violation reports can be sent[^1]. These enhancements aim at providing real-time feedback on potential security issues, enabling quicker responses from development teams. #### Broader Directive Support New directives may be introduced or existing ones expanded upon to cover additional aspects of web application security. For instance, there could be greater control over what resources can execute scripts, frame ancestors, object sources, etc., thereby reducing attack surfaces further. #### Integration with Emerging Web Standards As new standards emerge in areas like HTTP/3 adoption, CSP policies need to adapt accordingly. Expectations include seamless integration between these protocols ensuring consistent enforcement across different network conditions without compromising performance or user experience. #### Increased Focus on Privacy Protection With growing emphasis placed globally on privacy regulations such as GDPR, CCPA among others; future versions of CSP might incorporate features specifically designed to address personal data handling practices during content delivery processes while maintaining robustness against malicious activities. ```python # Example Python code demonstrating setting up basic CSP headers in Flask framework. from flask import Flask, make_response app = Flask(__name__) @app.route('/') def index(): resp = make_response("Hello World!") csp_header_value = ( "default-src 'self'; " "script-src 'self' https://trusted.cdn.com;" ) resp.headers['Content-Security-Policy'] = csp_header_value return resp ```
