- 26. SOC Process Number of processes and procedures for an SOC is determined by its scope, how many services are offered, the number of customers supported, and the number of different technologies in use. An established global SOC environment may have tens or even hundreds of procedures. At a minimum, the basic procedures that are required for maintaining the SOC are: • Monitoring procedure • Notification procedure (email, mobile, home, chat, etc.) • Notification and escalation processes • Transition of daily SOC services • Shift logging procedures • Incident logging procedures • Compliance monitoring procedure • Report development procedure • Dashboard creation procedure • Incident investigation procedures (malware, etc.) SIEM monitoring and correlation • Antivirus monitoring and logging • Network and host IDS/IPS monitoring and logging • Network and host DLP monitoring and logging • Centralized logging platforms (syslog, etc.) • Email and spam gateway and filtering • Web gateway and filtering • Threat monitoring and intelligence • Firewall monitoring and management • Application whitelisting or file integrity monitoring • Vulnerability assessment and monitoring

- 36. Securing the SOC- Security Controls It is imperative to protect SOC environment with following controls • Layered security – Information security for SOC users and Information – Physical security for SOC users, visitors and Infrastructure – Common security layer for entire information and based on contract additional security controls implemented • Information Security for SOC users and Infrastructure – Process level: ISMS(Information Security Management System) – Integration of security controls with SIEM/ Service desk tools – IDM: Authentication and Identity access management, Multi factor authentication – Network level: Firewall, IPS, VPN, Antivirus, Web filter software` – Desktop level: Antivirus, security compliance, Strong authentication and access control – Datacentre level: Firewall, IPS, VPN, Antivirus, Host based IDS – Access log: Syslog server for user audit trail and analysis
- 37. Securing the SOC- Physical Security Controls For SOC users, visitors and Infrastructure – Security guards on round the clock duty – Video Surveillance: monitor human movement – Biometric controls: For access to Datacenter and critical SOC areas – Tape vault: To store the logs generated in tapes and backup. This is statutory requirements – Access card: to operate doors and movement in and out of SOC – Visitor Management System: Register entry and pass generators, badge card for visitors – Glass and other barriers for dedicated space for certain clients in SOC

- 39. Summary of future SOC and new trends: • Future SOC will spend more time on security analytics and less time on device monitoring • New age SOC will use more resources to identify new, unknown threats/ malware/ malicious code and less time blacklisting known threats after attacks • Big Data will be part of SOC tool set • Out of the box SOC with lesser integration with different tool set in SOC • Integrated with Social sites to know human behavior and predict the attacks • Integrated with national agencies and international CERT to have uniform and instant response to attacks • Able to counter attack and stop all future activities from attackers from internet/ internal users • SOC will act as single agency to prevent security incidents, frauds happening in E- Systems, compliance of regional laws across geography boundaries • Will proactively provides alerts for financial frauds and violation in business process New trends
