Modern enterprises are saturated with telemetry. Endpoint agents, centralized logging, behavioral analytics, and automated detections have made off-the-shelf red team tools increasingly brittle and predictable. Most red team tools fail not because they're buggy, but because they behave in ways detection systems are designed to notice. Red Team Tool Development teaches readers how to think, design, and build differently. Instead of showing how to run popular frameworks, this book focuses on how offensive tools actually behave in monitored environments and why that behavior so often gives them away. The authors walk readers through the foundations of detection-aware tool design, explaining how payload structure, execution flow, and environmental interaction influence visibility across modern detection stacks. Each chapter centers on modular, adaptable examples that show not just what works, but why it works. Readers learn how small design decisions surface in logs, alerts, and behavioral analytics, and how thoughtful toolcraft can reduce detection while still achieving realistic adversary objectives. The result is a field-ready reference for red teamers who need to build their own tools when public ones fail, and for detection engineers and threat hunters who want a clearer view of how advanced operators design tooling to evade automated defenses.

Protect your information assets with effective risk management

In today’s information economy, the development, exploitation and protection of information and associated assets are key to the long-term competitiveness and survival of corporations and entire economies. The protection of information and associated assets – information security – is therefore overtaking physical asset protection as a fundamental corporate governance responsibility. 

Information security management system requirements

ISO 27000, which provides an overview for the family of international standards for information security, states that “An organisation needs to undertake the following steps in establishing, monitoring, maintaining and improving its ISMS […] assess information security risks and treat information security risks”. The requirements for an ISMS are specified in ISO 27001. Under this standard, a risk assessment must be carried out to inform the selection of security controls, making risk assessment the core competence of information security management and a critical corporate discipline.

The world's most infamous hacker offers an insider's view of the low-tech threats to high-tech securityKevin Mitnick's exploits as a cyber-desperado and fugitive form one of the most exhaustive FBI manhunts in history and have spawned dozens of articles, books, films, and documentaries. Since his release from federal prison, in 1998, Mitnick has turned his life around and established himself as one of the most sought-after computer security experts worldwide. Now, in The Art of Deception, the world's most notorious hacker gives new meaning to the old adage, "It takes a thief to catch a thief."Focusing on the human factors involved with information security, Mitnick explains why all the firewalls and encryption protocols in the world will never be enough to stop a savvy grifter intent on rifling a corporate database or an irate employee determined to crash a system. With the help of many fascinating true stories of successful attacks on business and government, he illustrates just how susceptible even the most locked-down information systems are to a slick con artist impersonating an IRS agent. Narrating from the points of view of both the attacker and the victims, he explains why each attack was so successful and how it could have been prevented in an engaging and highly readable style reminiscent of a true-crime novel. And, perhaps most importantly, Mitnick offers advice for preventing these types of social engineering hacks through security protocols, training programs, and manuals that address the human element of security.
