Code Explanation:
The program code above defines a Python class CybersecurityAudit
tailored for auditing websites for common cybersecurity vulnerabilities. The core of the program revolves around three main methods: get_links
, hash_file
, and check_files
.
get_links
is responsible for fetching all internal links from the specified domain that ends with certain file extensions. It uses therequests
library to make an HTTP GET request andBeautifulSoup
to parse the HTML content and extract the links.hash_file
generates a SHA-256 hash for a given file, mainly used for integrity checks. This ensures that a file has not been tampered with by comparing the calculated hash to a previously known value. Although thehash_file
method is included, it’s not utilized in this snippet. It’s a best practice to provide such functionality for auditing the integrity of files.check_files
takes the list of links and performs security checks on each. For the sake of simplicity, this function only checks for the presence of theX-Frame-Options
header, which is important for protecting against clickjacking attacks. If the header is missing in the HTTP response, a security issue is noted.
Finally, the program creates an instance of CybersecurityAudit
for the domain ‘http://example.com’, fetches internal links, and then checks each link for security issues. This simple demonstration targets a single aspect of security, but a full-fledged audit would include many more checks and validations, such as for Content Security Policy (CSP) headers, XSS vulnerabilities, and more.
By integrating these cybersecurity best practices, the program provides a starting point for automated audits but can be significantly expanded upon to assess a website’s security posture in depth.
