5 Going Mobile... and the Key Threats Access from anywhere Extensive access to corporate information New features added daily Hostile environment (public) Attractive target for attackers Increased attack surface Source: Dimension Research The impact of mobile devices on information security 5

6 Attack Vectors against Mobiles Source: Fraunhofer SIT: How Smartphones and Co. may be Cheating on you 6

7 Facts McAfee Threats Report: First Quarter 2013 the total number of samples in our mobile malware zoo reached 50,926, with 28 percent of that arriving in 2013 (source this is the Q1 report!) IP addresses in the United States are again both the source and the target of most malicious network activity. Q1 only! 7

8 Facts (continued) Attacks on Mobile devices focus either: Using the mobile to steal sensitive data Getting access data to backend systems Apple: 50% of smartphone users do not set up a passcode Phishing Companies from the United States are the most targeted, suffering 80 percent of all attacks. Phishing by country: 8

10 Where the data comes from Mobile Gateway C++ Application Java Application HTML Application ABAP RFC/BAdI SAP ALL Mobile apps eventually call ABAP programs

11 The Attack Surface of SAP

13 Since The Attack Surface of SAP

14 The Attack Surface of SAP Since NetWeaver Gateway

15 The Forgotten Layer Business Runtime SAP security must be addressed holistically Business Run-time Apps must properly enforce Business Logic GRC & SoD are only effective if they are enforced within the applications Business Logic Business Runtime Database Operating System

16 SAP System Security Tests Testing of >550 SAP Systems (including some of the largest organizations of the world) Over 95% of the systems analyzed were exposed to espionage, sabotage and fraud attacks None of the evaluated SAP systems were fully updated with the latest SAP security patches Most of these exploitable vulnerabilities have been publicly known to SAP customers for more than 5 years Source: Onapsis-BlackHat 2012

17 Increased External Access Points Increased External SAP Access Points

18 Never Trust the Other Side! - Security Paradigm Unsecured devices have access to sensitive backend systems (e.g. BYOD) 93% have mobile devices connected to their corporate networks The attacks against Mobiles continue to rise dramatically 52% of large companies say cost of mobile security incidents last year exceeded $500,000 45% have more than five times as many personal mobile devices as they had two years ago, a 36% increase from 2012 Best Practice: Stringently enforce device-level security Test and validate the complete application and data processing 18

19 Our SAP systems are secure

21 Source of Defects Source of Defects Little/no technical specifications Manual/Basic code reviews Testing focused on functional aspects External/3 rd Party development Limited/no code change monitoring

22 Definitions Average (Arithmetic Mean): Median: The value in the middle, when the numbers are sorted Example: 1,2,3,100,101 Median = 3 LOC = Lines of Code (without comments and empty lines) KLOC = 1 Thousand LOC MLOC = 1 Million LOC

31 Security Guidelines for SAP Culture Increase awareness of the need for SAP Security (for example, though workshops) Provide security training (Developer, Administrator, User, etc) Organization Make SAP Security an integral part of your corporate security strategy Develop company and partner security standards and processes that are binding! Compliance Make security a pre-requisite for all SAP projects Test that all delivered applications comply with security standards Add SAP Security to your audit activities Seite

32 Security Guidelines for SAP continued Technology Implement automated testing into your change control process to enable faster detection and mediation of security and quality defects Cost Awareness The earlier that defects are found, the less they cost to correct Cost of a correcting a single defect when found in: Unit testing (DEV) = $100 User Testing (QA) = $1,000 In productive system (PROD) =$10,000 After System failure, attack, = $?????? 32

33 ID Vulnerability Description BIZEC APP/11 Standard Security Tests Protecting Against Security Defects APP-01 ABAP Command Injection Execution of arbitrary ABAP Commands APP-02 OS Command Injection Execution of arbitrary OS Commands APP-03 Native SQL Injection Execution of arbitrary SQL Commands APP-04 Improper Authorization (Missing, Broken, Proprietary, Generic) Missing or incorrect Authorization Checks APP-05 Directory Traversal Unauthorized write/read access to files (SAP Server) APP-06 Direct Database Modifications Unauthorized Access to SAP Standard Tables APP-07 Cross-Client Database Access Cross-Client Access to Business Data APP-08 Open SQL Injection Malicious Manipulation of OSQL Commands APP-09 Generic Module Execution Unauthorized Execution of Modules (Reports, FMs, etc.) APP-10 Cross-Site Scripting Manipulation of the Browser UI, Identity Theft APP-11 Obscure ABAP Code Hidden / untestable ABAP Code

34 LEARNING POINTS Attacks on mobile Devices are rising exponentially. The combination of increased external (Web, mobile, etc.) applications has increased the diligence required by companies to ensure that their SAP systems are safe and stable. Custom ABAP and 3rd party code often have a relatively high number of defects that can introduce serious risks to your SAP production systems. Manual code reviews and basic tools offer no real protection at a relatively high cost.

35 RETURN ON INVESTMENT Implementing automated testing into your change control process will enable faster detection and mediation of security and quality defects The earlier that defects are found, the less they cost to correct Cost of a correcting a single defect when found in: Unit testing (DEV) = $100 User Testing (QA) = $1,000 In productive system (PROD) =$10,000 After System failure, attack, = $??????

36 BEST PRACTICES Enforce stringent security and quality standards for all custom and 3rd party code add them to contracts! Implement change control procedures that include automatic testing of all ABAP changes before importing to productive systems.
