Solution Components Solution Components Office Inventory Tool is no longer needed MBSA 1.2 (released in January 2004) includes Office scanning functionality Update Management Guidance Implementing a consistent, high quality update management process is the key to successful update management Microsoft delivers best practices prescriptive guidance as long as effective update management Uses Microsoft Operations Framework (MOF) Based on ITIL (defacto st in addition to ard as long as IT best practices) Details requirements as long as effective update management: Technical & operational pre-requisites Operational processes & how technology supports them Daily, weekly, monthly & as-needed tasks to be per as long as med Testing options Three update management guidance offerings Microsoft Guide to Security Patch Management Patch Management using Software Update Services Patch Management using Systems Management Server In as long as mation Technology Infrastructure Library Emphasizes security patching & overall security management Comprehensive coverage of patch management using the specified technology Assess Identify Evaluate & Plan Deploy
MBSA Helps identify vulnerable Windows systems Scans as long as missing security patches in addition to common security mis-configurations Scans various versions of Windows in addition to other Microsoft applications Scans local or multiple remote systems via GUI or comm in addition to line invocation Generates XML scan reports on each scanned system Runs on Windows Server 2003, Windows 2000 in addition to Windows XP Integrates with SUS & SMS MBSA: How It Works Microsoft Download Center MSSecure.xml MSSecure.xml contains Security Bulletin names Product specific updates Version in addition to checksum info Registry keys changed KB article numbers Etc. MBSA Computer Only covers security patch scanning capabilities, not security configuration detection issues SUS Server Downloads CAB file with MSSecure.xml & verifies digital signature Run MBSA on Admin system, specify targets Scans target systems as long as OS, OS components, & applications Parses MSSecure to see if updates available Checks if required updates are missing Generates time stamped report of missing updates Windows Update (WU) Microsoft online update service (windowsupdate.microsoft.com): Identifies missing Windows OS patches / updates on accessing computer Generates targeted list of missing updates Installs user selected missing updates Provides update installation history WU content can be automatically downloaded via Automatic Updates Supplemented by Windows Update Catalog site which provides: Comprehensive repository as long as all Windows in addition to Designed as long as Windows logo device driver updates Search to find desired update Manual download of desired updates Download history as long as accessing computer Windows 98 in addition to later versions. Note: also updates 64-bit editions of Windows Server
Windows Update: How It Works Scenario 1: User Initiated Access Scenario 2: Access via Automatic Updates (AU) Windows Update Client side code (CC) in browser (or AU) validates WU server & gets download catalog metadata User points browser to WU site & selects Scan as long as updates or AU automatically checks as long as new updates (every 17-22 hours) CC (or AU) uses metadata to identify missing updates WU (or AU – if so configured) lists missing updates in addition to user selects updates to download CC (or AU) downloads, validates, & installs updates. AU downloads using BITS, in addition to can be configured to allow user to select updates to install CC (or AU) updates history & statistics in as long as mation Note: No personally identifiable in as long as mation is collected.
