    3. 3. Today’s Agenda Today’s Threats Defenses – and What Does & Does Not Work Improving SMB Security Q&A
    4. 4. Today’s Threats

    9. 9. Typical SMB Defenses
    10. 10. Defense-in-Depth <ul><li>Traditional Defenses … </li></ul><ul><ul><li>Antivirus </li></ul></ul><ul><ul><li>Patching Microsoft OS and Apps </li></ul></ul><ul><ul><li>Firewalls </li></ul></ul><ul><ul><li>Strong Passwords </li></ul></ul><ul><ul><li>End-User Education Programs </li></ul></ul><ul><ul><li>… Don’t Always Work: If They Did, We Wouldn’t Have IT Security Breaches! </li></ul></ul>
    11. 11. Defenses – What Does Not Work
    12. 12. Defenses <ul><li>Where Traditional Defenses Fall Short </li></ul><ul><ul><li>Risk from Un-patched 3 rd Party Apps </li></ul></ul><ul><ul><li>Controlling Local Admins Gone Wild </li></ul></ul><ul><ul><li>Preventing Zero-Day Attacks and Targeted Malware </li></ul></ul><ul><ul><li>End-User Education Isn’t Keeping Up </li></ul></ul><ul><ul><li>Actionable Reporting and Security Measurement </li></ul></ul>
    13. 13. Why Antivirus Doesn’t Work <ul><ul><li>Swamped by the Deluge </li></ul></ul><ul><ul><li>Can’t keep up with rising daily volume of malware </li></ul></ul><ul><ul><li>Can’t defend against zero-day threats (on average, only 19% of new malware signatures are detected on day 1) </li></ul></ul><ul><ul><li>Severely impacts endpoint performance </li></ul></ul><ul><ul><li>36% of SMBs rely on free AV </li></ul></ul>
    14. 14. Hidden Costs of Antivirus <ul><li>Acquisition Costs </li></ul><ul><ul><li>Licensing (license cost, maintenance, support) </li></ul></ul><ul><ul><li>Installation (HW / SW, roll-out, other) </li></ul></ul><ul><li>Operational Costs </li></ul><ul><ul><li>System Managemenet </li></ul></ul><ul><ul><li>Incident Management (help desk, escalation, re-imaging) </li></ul></ul><ul><ul><li>Lost Productivity </li></ul></ul><ul><li>Extraordinary Costs </li></ul><ul><ul><li>Data Breach </li></ul></ul>Operational (60~80%) Acquistion (20~40%)
    15. 15. Why Patching Microsoft Alone Doesn’t Work <ul><li>Missing the Target </li></ul><ul><ul><li>Relying on “free” tools </li></ul></ul><ul><ul><li>Go beyond Microsoft </li></ul></ul><ul><ul><li>Most organizations take at least twice as long to patch 3 rd party application vulnerabilities than they do to patch OS vulnerabilities </li></ul></ul><ul><ul><li>60% of users are running un-patched versions of Adobe </li></ul></ul>
    16. 16. Hidden Costs of Free Patching <ul><ul><li>Why “Free” Can Cost You More </li></ul></ul><ul><ul><li>Speed and Accuracy </li></ul></ul><ul><ul><li>Time to deploy non-MSFT or custom application patches </li></ul></ul><ul><ul><li>No CVE information </li></ul></ul><ul><ul><li>Visibility and Compliance </li></ul></ul><ul><ul><li>Lack of hardware and software inventory </li></ul></ul><ul><ul><li>Limited reporting </li></ul></ul>
    17. 17. Defenses <ul><li>What Else Doesn’t Work </li></ul><ul><ul><li>Buying advanced tools, such as IDS, PKI, black-box solutions, while ignoring the basics </li></ul></ul><ul><ul><li>Preventing attack methods instead of shoring up IT risk sources and focusing on preventing malware execution </li></ul></ul>
    18. 18. Defenses <ul><li>Better End-User Education </li></ul><ul><ul><ul><li>Do your users know the company security policies and do they understand their importance? </li></ul></ul></ul><ul><ul><ul><li>Do you show your users what your “real” AV detection screen looks like? </li></ul></ul></ul><ul><ul><ul><li>Do they know that they are most likely to be infected from legitimate web sites, social media, USB keys, etc.? </li></ul></ul></ul>
    19. 19. Defenses – What Does Work
    20. 20. Defenses <ul><li>What Does Work </li></ul><ul><ul><li>Focusing on the Basics </li></ul></ul><ul><ul><li>Prioritize and Implement </li></ul></ul><ul><ul><li>Using past history to determine this year’s priorities </li></ul></ul><ul><ul><li>Make a ranked list and begin </li></ul></ul><ul><ul><li>Go for low hanging fruit first </li></ul></ul><ul><ul><li>Using Strong Data to Convince Management </li></ul></ul>
    21. 21. Focus on the Operational Basics Source: Aberdeen Group, Managing Vulnerabilities and Threats (No, Anti-Virus is Not Enough), December 2010 Assess Prioritize Remediate Repeat <ul><li>Identify all IT assets (including platforms, operating systems, applications, network services) </li></ul><ul><li>Monitor external sources for vulnerabilities, threats and intelligence regarding remediation </li></ul><ul><li>Scan all IT assets on a regular schedule for vulnerabilities, patches and configurations </li></ul><ul><li>Maintain an inventory of IT assets </li></ul><ul><li>Maintain a database of remediation intelligence </li></ul><ul><li>Prioritize the order of remediation as a function of risk, compliance, audit and business value </li></ul><ul><li>Model / stage / test remediation before deployment </li></ul><ul><li>Deploy remediation (automated, or manually) </li></ul><ul><li>Train administrators and end-users in vulnerability management best practices </li></ul><ul><li>Scan to verify success of previous remediation </li></ul><ul><li>Report for audit and compliance </li></ul><ul><li>Continue to assess, prioritize and remediate </li></ul>
    22. 22. Defenses – What Does Work <ul><ul><li>Augment existing defense-in-depth tools </li></ul></ul><ul><ul><li>Comprehensive Patch and Configuration Management </li></ul></ul><ul><ul><li>Application Control / Whitelisting </li></ul></ul><ul><ul><li>Device Control </li></ul></ul><ul><ul><li>Encryption </li></ul></ul>Blacklisting As The Core Zero Day 3 rd Party Application Risk Malware As a Service Volume of Malware Traditional Endpoint Security
