1 Protecting Mainframe and Distributed Corporate Data from FTP Attacks: Introducing FTP/Security Suite Alessandro Braccia, DBA Sistemi XXVIII Convegno Annuale del CMG-Italia Milano - 28 Maggio 2014 Roma 29 Maggio 2014

2 Agenda About SAC The Problem How Attackers Operate Popular Hacking Tools FTP Issues What the Products do and how Conceptual Overview Why are our products important?

3 About SAC Founded in 1990 Developed a number of very successful products Until now purely development company Products were private labeled by other companies, for ex: AF/Operator: Candle Corporation (now IBM) TapeSaver: Mobius Management Systems (now Unicom) These products have been sold or moved to subsidiaries Focus on the FTP/Security Suite Establishing Worldwide Partner Network

4 The Problem Complex problem, lack of understanding in market place Big vendors focus security discussion on their products Most attacks never make it to the press do not educate the market Customers often: Do not know how hackers operate Spend a lot of money on some solutions Lack tools in other (important) areas Result: Companies don t even know they were attacked or notice it many months later and don t know what was taken

5 How attackers operate Attackers can be Hobbyists, Amateurs or Professionals Use automated tools Attack weaknesses in common Tools and Protocols Prefer those that are not typically monitored Prime Target: FTP The world s most common data interchange protocol, including corporate IT Customers forget they use it, no one responsible No Management / Monitoring Tools By default attacks are typically not logged Attack tools available on internet, instructions on YouTube

6 Popular FTP Hacking Tools THC-Hydra ( Medusa ( Ncrack ( Brutus (

7 Search Hack FTP on YouTube

8 Where is FTP used? With External Partners Often hosting sensitive data On Web Servers Providing access to the corporate web site and other resources As departmental data interchange tool Often deployed without IT s knowledge & involvement Typically extremely vulnerable due to lack of security In the Data Center Server <-> Server and Server <-> Mainframe data transfer

9 FTP Issues Don t know where they use FTP and how much No Tools to monitor and audit FTP usage Lack of compliance Not able to detect attacks Not able to determine what was taken Not sufficiently protected against FTP attacks Firewalls and IDS (Intrusion Detection Systems) cannot do it

10 Intrusion Detection Systems Designed primarily to detect intrusions from outside Malicious employees and contractors are a common threat Looks for anomalies in network traffic Does not understand the network protocols it looks at Recognizes brute force attacks by frequency, not content Can be circumvented easily

11 The FTP/Security Suite FTP/Auditor: FTP Server discovery Where is FTP running, how is it secured? FTP/Sentry: Real-Time monitoring and alerting What is happening? What problems are occurring? Sentry Desktop: Auditing and historical analysis Who accessed which files - when and from where? Exceptions and Alerts FTP/Armor: Securing FTP Servers Detects attacks, alerts IT staff and blocks intruders Complements Intrusion Detection Systems FTP/Guardian: Integrates Mainframe FTP with Mainframe Security

12 Conceptual Overview Real Time Monitor Sentry Desktop Remote Agents FTP Activity DB (SQL Server)

13 Typical FTP Attack User: Administrator Password: AAAAA Password: AAAAB Password: AAABA Password: AAABB IP n.n.n.n

14 FTP Attack with FTP/Sentry User: Administrator Password: AAAAA Password: AAAAB Password: AAABA Password: AAABB Real Time Monitor IP n.n.n.n FTP Activity DB (SQL Server)

15 FTP Attack with FTP/Sentry User: Administrator Password: AAAAA Password: AAAAB Password: AAABA Password: AAABB Real Time Monitor Alert Console IP n.n.n.n Sentry Desktop

16 FTP Attack with FTP/Sentry User: Administrator Password: AAAAA Password: AAAAB Password: AAABA Password: AAABB BLOCK IP n.n.n.n BLOCK IP n.n.n.n Real Time Monitor IP n.n.n.n BLOCK IP n.n.n.n Remote Agents

17 FTP Attack with FTP/Sentry User: Administrator Password: AAAAA Password: AAAAB Password: AAABA Password: AAABB IP n.n.n.n Connection refused Remote Agents

18 Why are our products so important? Without them our Customers would not: Know which servers are vulnerable through running FTP Be protected against FTP attacks Be able to notice an attack what ID was compromised and what was taken Be able to audit WHEN WHO accessed WHAT from WHERE Have operational visibility and control of their FTP infrastructure

19 Interesting Studies & Reports Carnegie Mellon Software Engineering Institute: Insider Threat Study: Illicit Cyber Activity Involving Fraud in the U.S. Financial Services Sector Key Findings: An average of 32 months elapsed between the beginning of the fraud and its detection by the victim organization The insiders means were not especially sophisticated the fraud was possible due to lack of controls/security, not the skills of the perpetrators

20 Interesting Studies & Reports Forrester: Understand The State Of Data Security And Privacy: 2012 To 2013 Key Findings: Intentional Data Theft accounts for 45% of all Data Breaches 33% of Intentional Data Theft is committed by Malicious Insiders 66 % of Intentional Data Theft is committed by External Attacks

21 Interesting Studies & Reports Ponemon Institute: 2012 Cost of Cyber Crime Study: United States Key Findings: Average cost of a data breach in the US is $8,933,510 Certain industries, such as Financial Services, experience higher cost The companies in the study experienced an average of 1.8 successful attacks per week
