1 Patch Management Tools

2 Solution Components Analysis Tools Microsoft Baseline Security Analyzer (MBSA) Office Inventory Tool Online Update Services Windows Update Office Update Content Repositories Windows Update Catalog Office Download Catalog Microsoft Download Center Management Tools Automatic Updates (AU) feature in Windows Software Update Services (SUS) Systems Management Server (SMS) Prescriptive Guidance Microsoft Guide to Security Patch Management Patch Management Using SUS Patch Management Using SMS

3 Client Patch Management Options Consumer and Small Business: Windows Update User Initiated Deployment or Automated Updates Access to all available updates Deployment from Microsoft.com Medium Business: Software Update Services User Initiated Deployment or Automated Updates Administrator approved updates only Deployment from servers behind firewalls Enterprises: SMS and SMS Software Update Services Feature Pac k User or Administrator Initiated Deployments Administrator approved updates Deployment from servers behind firewalls ReportingScheduling

4 MBSA: What It Does Helps identify vulnerable Windows systems Scans for missing security patches and common security mis-configurations Scans various versions of Windows and other Microsoft applications Scans local or multiple remote systems via GUI or command line invocation Generates XML scan reports on each scanned system Runs on Windows Server 2003, Windows 2000 and Windows XP Integrates with SUS & SMS Evaluate & Plan New Update Deploy Identify Assess

5 MBSA: How It Works* Microsoft Download Center MSSecure.xml MSSecure.xml contains Security Bulletin namesSecurity Bulletin names Product specific updatesProduct specific updates Version and checksum infoVersion and checksum info Registry keys changedRegistry keys changed KB article numbersKB article numbers Etc.Etc. MBSA Computer *Only covers security patch scanning capabilities, not security configuration detection issues SUS Server 2.Downloads CAB file with MSSecure.xml & verifies digital signature 1.Run MBSA on Admin system, specify targets 3.Scans target systems for OS, OS components, & applications 4.Parses MSSecure to see if updates available 5.Checks if required updates are missing 6.Generates time stamped report of missing updates

6 MBSA 1.1.1

7 Windows Update: How It Works Scenario 1: User Initiated Access Windows Update Service 2.Client side code (CC) in browser validates WU server & gets download catalog metadata 1.User goes to Windows Update (WU) & selects ‘Scan for updates’ 3.CC uses metadata to identify missing updates 4.User selects updates to install 5.CC downloads, validates, & installs updates 6.CC updates history & statistics information* *Note: No personally identifiable information is collected. See

8 Windows Update: How It Works Scenario 2: Automatic Updates Initiated Access Windows Update Service 2.AU validates WU server & gets download catalog metadata 1.AU check WU service for new updates (every hours) 3.AU uses metadata to identify missing updates 4.AU either notifies user or auto-downloads using BITS & validates new updates 5.AU either notifies user or auto-installs updates 6.AU updates history & statistics information* *Note: No personally identifiable information is collected. See

9 SUS 1.0: What it Does Deploys Windows security patches, security rollups, critical updates*, and service packs only Deploys above content for Windows 2000, Windows Server 2003 and Windows XP only Provides patch download, deployment, and installation configuration options Bandwidth optimized content deployment Provides central administrative control over which patches can be installed from Windows Update Provides basic patch installation status logging *Including critical driver updates Evaluate & Plan Identify Assess New Update Deploy

10 SUS Benefits Gives administrators control over patch & update management Works with Group Policy* to prevent installs of non-approved updates from Windows Update Allows staging & testing of updates before installation Simplifies & automates key aspects of the patch management process Ease of use alleviates difficulty of keeping supported systems up-to-date, reducing security risks *Note: Use of SUS does not require implementation of Active Directory or Group Policy

11 SUS 1.0: How It Works Parent SUS Server Firewall Child SUS Server Bandwidth Throttling Windows Update Service Bandwidth Throttling 2.Administrator reviews, evaluates, and approves updates 1.SUS Server check for updates every hours 3.Approvals & updates synced with child SUS servers* 4.AU gets approved updates list from SUS server 6.AU either notifies user or auto-installs updates 7.AU records install history 5.AU downloads approved updates from SUS server or Windows Update *SUS maintains approval logs & download, sync, & install statistics

12 Client Component: Automatic Updates Centrally configurable to get updates either from corporate SUS server or Windows Update service Can auto-download and install patches under admin control Consolidates multiple reboots to a single reboot when installing multiple patches Included in Windows 2000 SP3, Windows XP SP1, and Windows Server 2003 Localized in 24 languages

13 Server Component: SUS Server Downloads updates from Windows Update Web based administration GUI Specify server & update process configuration options View downloaded updates Approve updates & view approved updates Security by design and default Requires NTFS; Installs IIS Lockdown and URL scanner* Supports secure administration over SSL Digital signatures on downloaded content validate authenticity Uses HTTP for content synchronization – only port 80 needs to be open Server side XML based logging on Web server Patch deployment & installation statistics Supports geographically distributed or scale-out deployments with centralized management for content synchronization & approvals Localized** in English & Japanese *If not already installed **Note: Delivers updates for all 24 supported client languages

14 SUS 1.0

15 SMS 2003: What it Does Identifies & deploys missing Windows and Office security patches on target systems Can deploy any patch, update, or application in Windows environments Inventory management & inventory based targeting of software installs Install verification and detailed reporting Flexible scheduling of content sync & installs Central, full administrative control over installs Bandwidth optimized content distribution Software metering and remote control capabilities Identify New Update DeployAssess Evaluate & Plan

16 SMS 2003 Patch Management: Benefits Gives administrators control over patch management Allows staging & testing of updates before installation Fine-grained control of patch management options Automates key aspects of the patch management process Can update a broad range of Microsoft products (not limited to Windows and Office) Can also be used to update third party software and deploy & install any software update or application High level of flexibility via use of scripting

17 SMS 2003 Patch Management: How It Works Firewall SMS Site Server SMS Distribution Point SMS Clients Microsoft Download Center SMS Distribution Point 2.Scan components replicate to SMS clients 1.Setup: Download Security Update Inventory and Office Inventory Tools; run inventory tool installer 3.Clients scanned; scan results merged into SMS hardware inventory data 4.Administrator uses Distribute Software Updates Wizard to authorize updates 6.Software Update Installation Agent on clients deploy updates 7.Periodically: Sync component checks for new updates; scans clients; and deploys necessary updates 5.Update files downloaded; packages, programs & advertisements created/updated; packages replicated & programs advertised to SMS clients SMS Clients

18 SMS 2003 Patch Management: Functionality System scanning & patch content download Content from Microsoft Download Center MBSA & Office Inventory plug-ins scan for missing patches Supports updating of remote & mobile devices Updates various versions of Windows, Office, SQL, Exchange, and Windows Media Player without need for update packaging / scripting Administrator control Update targeting based on AD, non-AD groups, WMI properties; additional options via scripting Patches content is downloaded from a central SMS repository only when the deployment process is initiated by the SMS administrator Specific start and end times (change windows); multiple change windows Easily move patches from testing into production Reference system patch configurations can be used as a template to verify or enforce compliance of systems that must mimic reference system configuration

19 Patch download & installation Delta replication (site-site, server-server) of patches Uses BITS* for mobile / remote client-server Uses SMB* for LAN / priority situations Reminders and rescheduling of install / reboot & enforcement dates Optimized graceful reboots, but forced when enforcement date arrives Per-patch reboot-needed detection to reduce reboots Status & Compliance Reporting Deployment status as patches are attempted Standard and customized reports through read-only SQL queries Determine actual baselines in the environment before changing the environment SLA measurement and rate-of-spread SMS 2003 Patch Management: Functionality (2) *Requires SMS Advanced Client
