The Open Web Application Security Project (OWASP) releases a comprehensive list of top vulnerabilities affecting networks and web applications. In this article, we explore the <strong>Top 10 OWASP Network Vulnerabilities<\/strong> and how to guard against them using tools and techniques available through platforms like <a href=\"https:\/\/spywizards.com\/\">SpyWizards.com<\/a>.<\/p>\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"1_Injection_Attacks_SQL_Command_LDAP\"><\/span><span class=\"ez-toc-section\" id=\"1_Injection_Attacks_SQL_Command_LDAP\"><\/span>1. <strong>Injection Attacks (SQL, Command, LDAP)<\/strong><span class=\"ez-toc-section-end\"><\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Injection vulnerabilities occur when untrusted data is sent to an interpreter. This can allow attackers to execute unintended commands or access data without proper authorization. <strong>SQL Injection<\/strong> is one of the most notorious forms. To protect against this, ethical hackers often perform <strong>network security penetration testing<\/strong> to identify weak points in applications.<\/p>\n<p><strong>Learn More:<\/strong> <a href=\"https:\/\/spywizards.com\/\">How to become an ethical hacker<\/a><\/p>\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"2_Broken_Authentication\"><\/span><span class=\"ez-toc-section\" id=\"2_Broken_Authentication\"><\/span>2. <strong>Broken Authentication<\/strong><span class=\"ez-toc-section-end\"><\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Broken authentication allows attackers to compromise passwords, keys, or session tokens.
