COLUMBIA SCHOOL DISTRICT WEB FILTERING

June 2007 We decided to enter into a 3 year contract with Secure Computing (N2H2) for Web filtering services because I did not believe that AT&T was going to have what we needed in time for school to start (Aug 2007) The 3 year was a 3 for 2 deal. (Cost about $3.00 per computer per year)

What CSD Demanded Ability to filter by groups (teachers, students, office and administrators) Ability to whitelist sites quickly. Ability to allow users to easily request site reviews. Ability to design a system that was difficult to beat. (Integration of filter with other security components)

Components of the Filtering System Management Server Filtering Server Reporting Server (Can be all in one)

Platforms for the Management & Reporting System –Windows 2000 SP4 –Windows 2003 SP2 –Windows 2003 SP1 –Windows XP Pro SP2 –Windows Vista –Red Hat ES 3.0 Update 6 –Red Hat ES 4.0 Update 2 –Red Hat ES 5.0 –Red Hat ES 5.1 –Solaris 8/9/10

Filter Server Platforms (IFP or Proxy) Check Point FireWall-1 Check Point FireWall-1 NGX R65 for Windows 2003 Server SP2 Cisco ASA – Adaptive Security Appliance (via IFP) Cisco Content Engine (via IFP) Cisco IOS Firewall (via IFP) Cisco PIX Firewall (via IFP) Cisco PIX v6.2 and later Microsoft ISA Server 2006 Microsoft ISA Server 2004 Microsoft ISA Server 2000 MS ISA Server 2000 SP2 for Windows 2003 SP2 MS ISA Server 2000 SP2 for Windows 2000 SP4 Nortel (via IFP) Nortel ACC v3.0 or later Nortel ASF SonicWALL (via IFP) SonicWALL v6.3 or later Squid Proxy Server Stratacache (via IFP) Sun Java System Web Proxy Server Sun Java System Web Proxy Server for Solaris 8, 9, and 10 Sun Java System Web Proxy Server for Solaris 8, 9 3Com SuperStack Blue Coat Proxy SG Blue Coat (Network Appliance) NetCache Cisco Content Engine and Content Engine Network Module (supported for SmartFilter and earlier versions) Computer Associates eTrust Intrusion Detection Computer Associates eTrust Secure Content Manager eSoft InstaGate Hewlett Packard TRU64 McAfee Secure Content Management Appliances NetIQ WebMarshal Netopia Parental Controls Novell BorderManager Secure Computing Sidewinder® G2 Firewall™ Secure Computing Sidewinder G2 Security Appliance

COLUMBIA SCHOOL DISTRICT RedHat 5.1 Proxy Server (At each school) Windows 2003 Management/Reporting (Central Office)

PROS 1.I am not at the mercy of AT&T 2.New filter sites updated every night 3.Update deployment is simple 4.Comprehensive Reporting 5.Ability to filter by, IP Address group or by Active Directory groups. 6.Proxy server method reduces network traffic. 7.Easy for users to request reviews. 8.Tech Support is OUTSTANDING!!!

CONS Not a piece of cake to install the Linux server applications. Recompiles Squid. Configuration of the manager was not very intuitive for me. Instructions were not very helpful. Presumed that the installer would understand the terms that were not used in the conventional sense.
