Updates for Microsoft SQL Server 2008 Express (64-bit edition) runs on each Microsoft Lync Server 2010 Standard Edition server (for the back-end database) and on all other Lync Server 2010 server roles (for the Local Configuration Store), unless you have upgraded these databases to SQL Server 2008 R2 Express. You should consider these databases as part of routine security update maintenance, as should SQL Server on the back-end database of a Front End pool, the Monitoring database, and the Archiving database. 25

Microsoft Lync Server 2010 Security Guide Best Practice Keep current with Windows Update. Addressing Threats at Your Internet Boundary for Lync Server 2010 The ability to communicate over the Internet with external employees, partners, and customers is clearly desirable. At the same time, your network is most vulnerable along its Internet boundary. Safeguarding that boundary is the single most important and effective step you can take maximizing the overall security of your Microsoft Lync Server 2010 network. This section describes the safeguards provided by Lync Server 2010 for various types of communications across the corporate firewall. It also includes recommended best practices for safeguarding your perimeter network. In This Section Edge Servers for Lync Server 2010 Firewalls for Lync Server 2010 Federation Safeguards for Lync Server 2010 HTTP Reverse Proxy for Lync Server 2010 Edge Servers for Lync Server 2010 The Microsoft Lync Server 2010 perimeter network is home to three edge services, each of which handles a particular type of traffic across the corporate firewall: The Access Edge service, formerly known as the Access Proxy, handles all SIP traffic crossing the corporate firewall. The Access Edge service is required for all external user scenarios, including conferencing, remote user access, federation, and public IM connectivity. The Web Conferencing Edge service proxies Persistent Shared Object Model (PSOM) traffic between the Web Conferencing service and external clients. External conference traffic must be authorized by the Web Conferencing Edge service before it is forwarded to the Web Conferencing service. The Web Conferencing Edge service requires that external clients use TLS connections and obtain a conference session key. The A/V Edge service provides a single trusted connection point through which audio and video traffic enters and exits your network. With an A/V Edge service, users can: Add audio and video data to meetings with external participants. Share audio and video directly with an external user (point-to-point). Share their desktop and applications with external users through the Application Sharing Server, using IM and conferencing. The A/V Edge service also handles audio for Enterprise Voice for external users.

    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.
