ITSD Division Overview and Cybersecurity Threat Landscape
- 1. Information Technology Services Division , ITSD - Abhinav Biswas Alt. CISO, NKN Data Centre, Electronics Corporation of India Limited, ECIL Department of Atomic Energy.
- 2. Information Technology Services Division , ITSD • Corporate Threat Landscape • Signature Based • Analytics based (Sandboxing & GTI ) • Log Correlation & Big Data Analysis • Nessus, Acunetix
- 3. Information Technology Services Division , ITSD Gathers information secretly and sends to another entity without the user's consent. Stops from using your PC until you pay a certain amount of money (the ransom). e.g. Encryption Ransomware, CryptoLocker Psychological manipulation of people into performing actions or divulging confidential information. Act of attempting to acquire information such as usernames, passwords, and credit card details by masquerading as a trustworthy entity in an electronic communication. Voice-over Phishing
- 4. Information Technology Services Division , ITSD A weakness which allows an attacker to reduce a system's information assurance. A possible danger that might exploit a vulnerability to breach security and thus cause possible harm. A piece of software or a sequence of commands that takes advantage of a bug or vulnerability. An attempt to destroy, expose, alter, disable, steal or gain unauthorized access to or make unauthorized use of an asset. (A realized Threat using an Exploit on Vulnerability is an Attack.) An observable change to the normal behavior of a system, environment, process, workflow or person. An event attributable to a root cause. All incidents are events but many events are not incidents. (An Attack is a series of security incidents.)
- 5. Information Technology Services Division , ITSD - Advanced Persistent Threats (APT) - Zero-day Attacks (ZDA) - Smart Mobile Malware (SMM) - Web-based Plug-in Exploits (WPE) - Free availability of Root-kits, SpamBots, Phishing Tools etc. - Digital Currencies (BitCoin) & Anonymous Payment Services. - Strategic Government institutions. - Polymorphism, Dynamic URLs, Virtualization, Cloud, Smart Phone/ Mobiles, Social Sites, BYOD, Internet Of Things (IOT/IPv6)
- 6. Information Technology Services Division , ITSD Lure Redirect Exploit Kit Dropper File Call Home Data Theft Recon
- 7. Information Technology Services Division , ITSD 7 Social Media Email Mobile Attack Vectors Web Redirects Malware Recon XSS Dropper Files C n CExploit Kits Phishing
- 8. Information Technology Services Division , ITSD • 1a) Identify target • 1b) Determine browsing habits • 2) Select favorite website • 3) Compromise and host exploits • 3)Drop malware • 4)Determine target profile • 4)Wait for opportunity to further compromise
- 9. Information Technology Services Division , ITSD Internet Customer Attacker Vuln. ADSL Router Changes the DNS server entries in the modem to rogue DNS servers and changes the password of the DSL router Rogue DNS Server Attacker scans for the DSL router and logs onto Admin console via WAN interface by exploiting vulnerabilities in the router firmware or configuration flaws; or by infecting connected computer
- 10. Information Technology Services Division , ITSD 3 FORWARD FACING ONLY, LACK OUTBOUND PROTECTION No contextual analysis of Internal Threats. 2 LACK OF REAL-TIME INLINE CONTENT ANALYSIS No Byte-Range Data Packet Analysis for Data Loss/ Theft Detection 4 LACK OF ADVANCED ANALYTICS & ANOMALY DETECTION No Sandboxing in existing UTMs, NGFWs. No SSL packet inspection. 1 PRIMARILY BASED ON SIGNATURE & REPUTATION Signature history cannot keep up with the dynamic future of threats

Information Technology Services Division , ITSD WEB Content Analysis Malware Sandbox Forensic Reports SSL Inspection Video Controls EMAIL Spear-Phishing URL Sandboxing Anti-Spam TLS Encryption Image Analysis DATA Content Aware DLP Drip Data Theft Detection OCR of Image Text Geo-Location MOBILE Cloud Service Malicious Apps BYOD Policy Reporting/Invent ory Monitor Discover Classify DISCOVER MONITOR CLASSIFY PROTECT WHERE WHATWHO HOW ESSENTIAL INFORMATION PROTECTION External Risks Internal Risks
- 13. Information Technology Services Division , ITSD
- 14. Information Technology Services Division , ITSD (Similar to Bomb Detonation Sandbox) - Tightly controlled access to resources - URL sandbox/File sandbox - Isolated environment/network - Multiple Detection Environment (Virtual Machines) - Customizable & Realistic Virtual environment - Behavior based classification & Risk scoring - Instrumented Forensic Data Collection - Big log Data interpretation - Post-incident data (SIEM - Security Incident Event Management) - Real-time Threat Intelligence (GTI) - Integration with other sources (local/national/international) - PCAP (Packet Capture) & Replay
- 15. Information Technology Services Division , ITSD - Content & Context Aware logs - Device & Application logs, Authentication & IAM log, Endpoint security devices, user identity, location, VA scan data, Netwrk flows, OS events, DB transaction logs - Remove redundancy. - Threat Intelligence & Risk Analysis - Behavior Profiling
- 16. Information Technology Services Division , ITSD
- 17. Information Technology Services Division , ITSD - Concept of the network perimeter evaporates - No Physical Segregation across VMs - Web access to all Resources - VM to VM vulnerability exploitation (Colocation of VMs) - Easy Reconfiguration (Lack of Persistence) - Still a hot research topic - Instance Isolation in Software Defined Data Centre (SDDC) - Homo-morphic encryption based virtual disks. - Randomized Memory Mapping & Distributed Scheduling.

Editor's Notes
- Security Challenges faced by todays security administrators. APT – New model of targetted attacks. Tradition Defense – Why they fail in present scenario? Focus on new technology – SIEM Virtual – New threats emerging from adoption of VMs VA/PT – Why they are necessary?
- I assume, - Aware of basic terminologies like, malware, virus, trojans, rootkits etc. Spyware - New form of malware. – Very stealthy in nature with No symptoms Social Engg – People are much more social online than offline becoz of platforms lik FB, watsapp. - friendly conversation, digging out sensitive info. Spear-Phishing mail – Online SBI Vishing – Abrupt way of psychological manipulation – Call from MD & send mail
- APT – Targetted attacks which specific goals 0-day - vulnerabilities which are not yet detected or no patch available. Bad guys. Mobile – App Permissions : Chat App - access to mail, browsing history etc. - Not save Payment credentials. Plugins- Wordpress – developed by third party – not tested Free – Tools like Metasploit Stuxnet – Designed by america in collaboration with Israel for Iraninan nuclear reactors- 0-day flaws of Siemens PLC software - Increased the spinning speed of centrifuges and got burnt, whole plant came down
- APT – Sophisticated attack targetted to a specific organisation for steal confidential info like IP Not 1 or 3 people – Organisation of people working together It’s not just spread malware and say spread it to 10 million people if there’s a 1% hit that’s fine no. Specific to a particular system or person. Drip data – bit by bit – different locations Strength of a chain depends on weakest link. Weakest link is human, lets see how. Stealthy Can span across a duration of days to years. Common cold vs Cancer
- Stuxnet- PLC technician went inside with laptops which were infected. They were not aware. Other ways, - Throw Pendrives.
- Browser fingerprinting. Ads based on browsing history. Discounts on product.
- www.ipeindia.org How DNS works?
- How Antivirus works? Only Packet Headers Inspection. Insider threats. Bad guy with malicious intention. Mail Administrators can check mail if not encrypted.
- 3 aspects of Data – CIA App – Unnecessary services & ports Network – NAC, NMS, ECIL SNAS No access to datacentre, DC & DR security
- Some advanced techniques. Content – Not just headers. Full packet inspection Video - Websense SSH, Remote shell login Drip Data
- Apart from them, New Advanced Technologies
- Market leaders – HP & IBM
- Both Good and Bad guys use it. Ethical hacking.
- System integrity – Tripwire VPN UTM How much is it worth investing> Criticality of data. Famous Quote – “If someone steals your password, you can change it. But if someone steals your thumbprint, you can’t get a new thumb.”
