  4. C-DAC Trivandrum An ISO 9001-2000 certified premier R&D Institution involved in the design, development and deployment of world class Electronic and IT solutions for economic and human advancement, under Department of Information Technology, Government of India Established in 1974 as Keltron R&D Center; Taken by GoI in 1988; Formerly Known as ERDCI Work force of 800+

  5. AREAS OF RESEARCH • Control & Instrumentation • Power Electronics • Broadcast & Communications • Strategic Electronics • ASIC Design • Cyber Forensics

  6. Resource Centre for Cyber Forensics The Resource Centre for Cyber Forensics (RCCF) is the premier centre for cyber forensics in India. It was setup in C-DAC, Thiruvananthapuram by the Ministry of Communications and Information Technology and has been functioning for the past three years. The primary objectives of RCCF are • Develop Cyber Forensics tools based on requirements from Law Enforcement Agencies (LEA) • Carry out advanced research in cyber forensics • Provide technical support to LEA Resource Centre for Cyber Forensics

  7. Current Threat Landscape Resource Centre for Cyber Forensics

  8. E-Commerce Today • Practically every organization and every network connected user are engaged in some form of e-commerce • Some of the categories are • Consumer e-commerce (Web stores and auctions), digital products (software downloads), content, back-end systems (payment, catalogues), B2B commerce, trading networks, and advertising • Communications systems (email), social networking sites are also getting into e-commerce Resource Centre for Cyber Forensics

  11. Major Security Concerns Threats and criminals are becoming faster, smarter and more covert Criminals are exploiting vulnerabilities along the entire Web ecosystem to gain control of computers and networks “Invisible threats” (such as hard-to-detect infections of legitimate websites) are making common sense and many traditional security solutions ineffective.

  12. Malware for financial fraud Infostealer malware – Banking Trojans – Keyloggers (Form grabbing) – Remote Login websites Botnets – Spam – Hosting Phishing websites, Malware – Operation of infected system Automated attack toolkits – Propagation of malware – Stealing information Automated Phishing/Fraud Toolkits Resource Centre for Cyber Forensics

  13. What is Typically Stolen • User IDs • Passwords • Credit card numbers • Bank Account details • Personal Information Numbers • Social Security Numbers • Email ids Resource Centre for Cyber Forensics

  14. Security Issues in Banking • ReadiMinds a, specialist, transactional security & fraud prevention software company, recently conducted a survey on 'State of Online Security in Financial Institutions in India - 2008'. Respondents represented cross-section of India's top 40 banks. The study primarily focused on the issues pertaining to online identity theft and online financial frauds. Key findings of this survey: • 30% of banks reported to have been victims of identity theft during the last one year. • 30% of banks reported to have been victims of phishing during the last one year. (The figure for Asian Banks is 25%) 25-Sep-14 Resource Centre for Cyber Forensics 14

  15. Need of the Hour Enterprises must have a procedural and technical infrastructure in place to respond immediately to computer-related security breaches and investigate malicious activity and employee misconduct An Enterprise Investigation solution with incident response capability is required for a complete security solution. This solution has to bring computer forensic technology to the enterprise along with incident response and investigation capability – an Enterprise Forensics and E-Discovery solution 25-Sep-14 Resource Centre for Cyber Forensics 15

  17. Enterprise Forensics - Advantages • Enterprise Forensics provides very effective monitoring of networked computers. The actions allowed on remote machines can be configured and monitored from a server. Any nefarious activity on the monitored machines is immediately tracked and necessary actions to counter such activities can be automatically initiated. • Securely investigate/analyze many machines simultaneously over the LAN/WAN at the disk and memory level. • Acquire data in a forensically sound manner. • Limit incident impact and eliminate system downtime with immediate response capabilities. • Investigate and analyze multiple platforms using a single tool. • Efficiently collect only potentially relevant data upon requests. 25-Sep-14 Resource Centre for Cyber Forensics 17

  18. Enterprise Forensics - Advantages • Proactively audit large groups of machines for sensitive or classified information, as well as unauthorized processes and network connections. • Identify fraud, security events and employee integrity issues wherever they are taking place and investigate/remediate with immediacy without alerting targets. • Identify and remediate events, injected DLLs, Rootkits and hidden/rogue processes. 25-Sep-14 Resource Centre for Cyber Forensics 18

  19. E-Discovery Required to enforce legal holds and automatically search, identify, collect, preserve and process electronically stored information across the network E-discovey allows to search and collect relevant Electronically Stored Information (ESI) across the network without disruption and preserves ESI. It also helps in avoiding over-collection of information 25-Sep-14 Resource Centre for Cyber Forensics 19

  20. E-Discovery Advantages Highly scalable Operates from a central location, with no disruption to end- users Highly flexible, automated search & collection based on: — File type (e.g., .doc, .xls, .ppt) — Key words (target specific content) — Metadata (created, last-written/last-accessed times etc.) — Patterns (e.g., social security or credit card numbers) — Hash values (i.e., “digital fingerprints”) — Custodians (by user name or SID) — Foreign Language Support (Unicode & code pages) 25-Sep-14 Resource Centre for Cyber Forensics 20
