Mastering Cyber Intelligence

By: Jean Nestor M. Dahj

Overview of this book

The sophistication of cyber threats, such as ransomware, advanced phishing campaigns, zero-day vulnerability attacks, and advanced persistent threats (APTs), is pushing organizations and individuals to change strategies for reliable system protection. Cyber Threat Intelligence converts threat information into evidence-based intelligence that uncovers adversaries' intents, motives, and capabilities for effective defense against all kinds of threats. This book thoroughly covers the concepts and practices required to develop and drive threat intelligence programs, detailing the tasks involved in each step of the CTI lifecycle. You'll be able to plan a threat intelligence program by understanding and collecting the requirements, setting up the team, and exploring the intelligence frameworks. You'll also learn how and from where to collect intelligence data for your program, considering your organization level. With the help of practical examples, this book will help you get to grips with threat data processing and analysis. And finally, you'll be well-versed with writing tactical, technical, and strategic intelligence reports and sharing them with the community. By the end of this book, you'll have acquired the knowledge and skills required to drive threat intelligence operations from planning to dissemination phases, protect your organization, and help in critical defense decisions.

Integrating threat intelligence into SIEM tools – Reactive and proactive defense through SIEM tools

In an organization with no CTI program, a SIEM tool collects system logs and internal documentation from all devices (servers, wireless access points, firewalls, IDSs, and IPSs), applications (for example, software applications and protocol applications), and endpoints (for example, PCs, printers, and mobile devices) that connect to the network. It collects data from different system environments and different formats. It then consolidates, correlates, and converts that data to human-readable formats. Systems and people can query the processed data to identify abnormal activities. The SIEM system generates alerts (alarms) that indicate possible threats or attacks. All system events and flows must be logged to ensure proper internal visibility. A SIEM system can help with reactive and proactive system defense depending on the detected activity. A reactive defense is the system...
