The flexibility of CPL ensures that organizations can implement tailored security policies that align with their operational and compliance requirements. Unlike static access control lists, CPL enables complex, context-aware policies that adapt to changing network conditions, user roles, and business needs.

Basic CPL Constructs

CPL is structured around several core constructs, including variables, operators, conditions, and actions. Variables store information about the request or user, such as the URL, client IP address, or authenticated username. Operators define how variables are evaluated, such as equals, contains, or matches regular expression. Conditions are used to combine variables and operators into logical statements, determining when a policy rule should be applied. Actions define what happens when a condition is met, including allowing, denying, redirecting, or logging the request.

Understanding these constructs is essential for building effective CPL scripts. Basic CPL syntax requires precise attention to detail, as errors in script structure or logic can result in policy misconfigurations that impact user experience or security enforcement.

Creating Effective CPL Policies

Effective CPL policies require careful planning and organization. Administrators must first identify the objectives of the policy, whether it is to enforce web usage restrictions, implement malware scanning, or manage bandwidth utilization. Policies are then structured hierarchically, allowing multiple conditions and actions to be evaluated in sequence.

For example, a policy may first check whether the request originates from a specific user group, then evaluate the requested URL against a category filter, and finally determine the appropriate action, such as blocking access or redirecting to a compliance notice. By layering conditions and actions, administrators can create nuanced policies that address a wide range of scenarios.

Advanced CPL Techniques

Advanced CPL scripting allows for more sophisticated policy logic, including loops, conditional branching, and the use of regular expressions.

Blue Coat ProxySG provides robust SSL proxying capabilities to address these challenges, allowing organizations to intercept, decrypt, inspect, and re-encrypt SSL/TLS traffic while maintaining end-to-end security. Mastery of SSL proxying and encrypted traffic management is a core competency for Blue Coat Certified ProxySG Professional (BCCPP) candidates, as it directly impacts the ability to enforce policies and secure enterprise networks in modern environments.

Fundamentals of SSL Proxying

Secure Sockets Layer (SSL) and Transport Layer Security (TLS) are cryptographic protocols designed to protect the confidentiality and integrity of data transmitted over networks. While these protocols prevent eavesdropping and tampering, they also prevent security appliances from inspecting traffic using traditional methods.

ProxySG addresses this challenge by acting as an intermediary between clients and servers in a process known as SSL interception or SSL proxying. The appliance decrypts the incoming encrypted traffic, evaluates it according to pre-configured policies, and then re-encrypts the traffic before forwarding it to its destination. This enables organizations to apply critical security controls such as content filtering, malware scanning, authentication enforcement, and data loss prevention to encrypted traffic without compromising the trust established by SSL/TLS.

SSL proxying provides significant security benefits. It allows administrators to identify hidden threats that leverage HTTPS for communication, such as command-and-control traffic, ransomware, or credential-stealing payloads. By inspecting traffic at the application layer, administrators can implement granular controls, ensuring that policy enforcement is precise and effective.

Configuring SSL Proxying on ProxySG

Configuring SSL proxying requires careful planning to balance security, performance, and privacy considerations. The process begins by enabling SSL interception on the ProxySG appliance and defining SSL proxy rules.

Advanced Authentication Mechanisms

Authentication is one of the most crucial aspects of ProxySG deployment. It ensures that users are verified before gaining access to network resources, thereby preventing unauthorized access while maintaining usability. Enterprises often face the challenge of securing access for a diverse range of users—including employees, contractors, guests, and remote users—while minimizing friction and maintaining productivity. ProxySG supports multiple authentication methods to address these requirements.

Kerberos authentication provides seamless internal access for employees within a corporate network. By using ticket-based authentication, Kerberos allows users to log in once and gain access to multiple resources without repeatedly entering credentials. This method improves user experience, reduces password fatigue, and mitigates the risk of credential theft. Additionally, Kerberos supports mutual authentication, allowing both clients and servers to verify each other’s identity, thereby protecting against man-in-the-middle attacks and impersonation threats.

The Blue Coat Authentication and Authorization Agent (BCAAA) serves as a centralized gateway for authentication and access control, enabling organizations to integrate ProxySG with enterprise identity systems such as Active Directory, LDAP, or other directory services. BCAAA allows administrators to enforce role-based access policies, ensuring that users access only the resources appropriate for their role. This centralized approach reduces administrative overhead and ensures consistent enforcement of security policies across the enterprise. BCAAA also supports multi-factor authentication (MFA), which adds an additional layer of security for high-risk users or sensitive applications, such as financial systems or confidential data repositories.

Guest authentication addresses the need for temporary access for contractors, visitors, or third-party collaborators. Through controlled guest portals, organizations can provide time-limited access to specific resources without granting permanent credentials. These portals often include bandwidth restrictions, URL filtering, and logging capabilities, allowing administrators to maintain oversight and enforce policy compliance. Guest authentication ensures secure access for external users while protecting internal resources and sensitive information.

By combining these authentication mechanisms, organizations can implement a layered security model. Internal users can authenticate seamlessly through Kerberos, privileged users can authenticate via BCAAA with MFA, and temporary users can access resources through secure guest portals. This multi-layered approach not only enhances security but also supports regulatory compliance by providing detailed logs and audit trails for all authentication events. In practice, enterprises benefit from improved security posture, reduced risk of unauthorized access, and a better balance between usability and control.

SSL Proxying and Encrypted Traffic Management

The increasing adoption of HTTPS and other encrypted protocols has created new challenges for enterprise security.

By inspecting encrypted traffic, administrators can identify and block threats that would otherwise bypass traditional security controls.

Certificate management is another essential aspect of SSL proxying. ProxySG requires certificates for client-side and server-side communications. Administrators must generate, import, export, and renew certificates to maintain trust and uninterrupted operation. Managing certificate authorities, monitoring expiration dates, and handling revocation lists are critical tasks to prevent trust issues, connection failures, and potential vulnerabilities. Proper SSL certificate management ensures seamless communication, reduces client errors, and maintains enterprise security integrity.

Compliance and legal considerations are also central to SSL proxying. Decrypting traffic can raise privacy concerns and regulatory obligations, particularly in sectors such as healthcare, finance, and government. Organizations must ensure that SSL inspection policies comply with data protection laws, clearly define which traffic is intercepted, and establish mechanisms to protect sensitive information. Logging and reporting help demonstrate compliance and provide transparency for audits. Selective decryption policies allow organizations to inspect high-risk traffic while excluding sensitive domains to maintain user privacy and regulatory adherence.

Performance optimization is essential to prevent SSL proxying from degrading user experience. Decrypting and inspecting encrypted traffic increases processing overhead. Administrators must allocate resources effectively, configure multiple SSL workers, implement caching strategies, and monitor appliance performance using SGOS diagnostic tools.
