            try:
                response = requests.get(link)
                # Check for any wrong headers or contents in the file
                if response.headers.get('X-Frame-Options') is None:

            except Exception as e:
                print(f'An error occurred while checking file {link}: {e}')

if __name__ == '__main__':
    domain_to_audit = 'http://example.com'
    audit = CybersecurityAudit(domain_to_audit)
    internal_links = audit.get_links()
    audit.check_files(internal_links)

Code Output:

Checking http://example.com/about.html...
Security issue found in http://example.com/about.html: Missing X-Frame-Options header.
Checking http://example.com/contact.js...

Security issue found in http://example.com/privacy-policy.txt: Missing X-Frame-Options header.

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 the requests library to make an HTTP GET request and BeautifulSoup 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 the hash_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 the X-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.
