IT Professionals

Windows Systems Administrators are expected to implement Internet Protocol Security (IPSEC) policy within their server environment. IPSEC should be deployed in addition to host based firewalls for an added layer of protection. The ITSG provides stock IPSEC policies for Windows File, Web, FTP, MSSQL and MYSQL servers. The stock policies restrict access to Drexel subnets and provide limited inbound and outbound access to the Internet.

IPSEC Policy Downloads
