Web Exploits: SQL Injection / Cross-site Scripting
Botnets: Updating and Modifications
BYOD: Personal and Professional usage
Data Loss: Intellectual Property Protection, Health data, Compromises
Failed Trust: Certificate system, authentication
Big data : Greater storage of data = greater liability
Internet of things : greater attack surface
Cloud & Virtualization
Evolution of SCADA networks to IP
Virtual / common currencies
Targeted and Persistent Attacks
Sponsored Cyber Operations: espionage, attacks, offensive security

Security Operations Center
• SOC is a centralized location where an organization’s security,
network, end-user devices and systems are monitored.
• Through people, processes and technology, a SOC is dedicated
to detection, investigation, and response of log events
triggered through security related correlation logic.
• Delivers 24x7x365 security management, monitoring and
reporting services.

Vulnerability Management
• VM services covers four activities - Vulnerability Assessment of IT assets, validation of
identified vulnerabilities, Providing Recommendations and Reporting
• Provides an independent baseline and validation of the organization’s security posture.
• Risk analysis and develop remediation plans that are tailored to unique business
requirements and security needs
Vulnerability Assessment
• Scanning of the target infrastructure,
establishing a baseline and making
compliance easier by validating external
posture
Penetration Testing
• Manual testing and exploits, in addition
to false positive reduction of automated
results
• Providing an overall security picture at a
lower cost with repeatable exercises
• Verifying that defense in depth and
response capabilities are working as
designed, along with security controls
validation
• Periodically verifying assets are properly
protected; evaluating recurring
differentials and managing vulnerabilities
• Required by many industry regulations
and standards

Network & Security Operations
The NOC’s purpose has always been to ensure "power, ping, and pipe" to
computing resources and is critically measured on uptime. Conversely, the SOC’s
purpose has been to "protect, detect, react, and recover" and is critically measured
on response time.
