Microsoft Lync Server 2010 Security Guide Security Framework for Lync Server 2010 This chapter provides an overview of the fundamental elements that form the security framework for Microsoft Lync Server 2010. Understanding how these elements work together is essential for making informed decisions about securing your particular Lync Server 2010 deployment. These elements are as follows: Active Directory Domain Services (AD DS) provides a single trusted back-end repository for user accounts and network resources. Role-based access control (RBAC) enables you to delegate administrative tasks while maintaining high standards for security. Public key infrastructure (PKI) uses certificates issued by trusted certification authorities (CAs) to authenticate servers and ensure data integrity. Transport Layer Security (TLS), HTTPS over SSL (HTTPS), and mutual TLS (MTLS) enable endpoint authentication and IM encryption. Point-to-point audio, video, and application sharing streams are encrypted using Secure Real-Time Transport Protocol (SRTP). Industry-standard protocols for user authentication, where possible. Windows PowerShell provides security features that are enabled by default so that users cannot easily or unknowingly run scripts. These fundamental security elements work together to define trusted users, servers, connections, and operations to help ensure a secure foundation for Lync Server 2010. The topics in this section describe how each of these fundamental elements works to enhance the security of your Lync Server infrastructure.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
