8 Web Security Threats and Vulnerabilities

Injection Attacks: Malicious code is injected into the website to execute unauthorized commands, such as SQL injection or cross-site scripting (XSS).
Cross-Site Request Forgery (CSRF): A malicious website tricks a user into performing an unwanted action on a trusted site.
Session Hijacking: An attacker steals a user's session ID to gain unauthorized access to their account.
Phishing: Attackers attempt to trick users into revealing sensitive information, such as passwords or credit card details.
Denial of Service (DoS) Attacks: Overwhelming a website with traffic to make it unavailable to legitimate users.
Malware: Malicious software that can infect a website and compromise its security.
Weak Password Policies: Using weak or easily guessable passwords can make a website vulnerable to attacks.
Unpatched Vulnerabilities: Failing to update software and plugins can leave the website exposed to known vulnerabilities.

8 Web Security Measures

Strong Passwords: Encourage users to create strong, unique passwords and use two-factor authentication.
TLS/SSL: Use Transport Layer Security (TLS) or Secure Sockets Layer (SSL) to encrypt data transmitted between the website and users.
Regular Updates: Keep software and plugins up-to-date to address security vulnerabilities.
Input Validation: Validate user input to prevent injection attacks.
Security Headers: Implement security headers like HTTP Strict Transport Security (HSTS) and Content Security Policy (CSP) to protect against common attacks.
Firewall: Use a firewall to protect your website from unauthorized access.
Web Application Firewall (WAF): Deploy a WAF to detect and block malicious attacks.
Security Audits: Conduct regular security audits to identify and address potential vulnerabilities.
