Study Notes
Module 1 - Threat Modeling Overview
- Threat modeling is a strategic process for identifying potential attack scenarios and vulnerabilities in applications, used to clearly identify risk and impact levels.
- Each function in the threat modeling process requires careful consideration of multiple risk factors influenced by threat, vulnerability, and impact levels.
- A key characteristic of threat modeling is its strategic approach, anticipating threats via calculated and simulated attack patterns.
- Threat modeling is a chain-like reaction of tactical events across multiple domains (e.g., business objectives, system/database administration, vulnerability management).
Threat Modeling Overview - Definition, Origin, and Use (Process)
- Threat modeling's process is a key distinguishing quality.
- It involves a chain-like reaction of tactical events across multiple domains, with input and contributions from other stakeholders related to a protected application environment.
Threat Modeling Overview - Definition, Origin, and Use (Attack)
- Attack reflects a major science in threat modeling.
- The discipline involves researching how attack patterns may exploit software vulnerabilities;
- Threat modeling techniques dissect attacks, exposing faults in design and development, and unveiling attacker motivations.
Threat Modeling Overview - Definition, Origin, and Use (Vulnerabilities)
- Vulnerabilities are more prevalent in other IT security efforts.
- Threat modeling uses vulnerabilities at platform and software levels to aggregate and correlate with possible attack scenarios.
Threat Modeling Overview - Definition, Origin, and Use (Application Environment)
- The application environment is the object of the threat modeling process.
- Other security procedures typically address single aspects of an application, lacking a holistic approach.
- Threat modeling's value is in encompassing benefits of isolated procedures to secure the entire application environment.
Threat Modeling Overview - Definition, Origin, and Use (Risk)
- Risk is the key interest in threat modeling, a supportive role in achieving business objectives.
- Threat modeling identifies risks from evolving threats, compounded by software/network vulnerabilities, and driven by attack motives in business information within an application environment.
Threat Modeling Overview - Definition, Origin, and Use (Threat Modeling)
- Threat modeling provides precise risk communication by clarifying how a business application environment could be compromised and the probability of actual risk.
- Risk unifies security and business professionals for collaborative enterprise protection.
Threat Modeling Overview - Definition, Origin, and Use (Impact)
- Impact is the ability to properly answer the question "How bad is it?".
- Security professionals must consider all possible threat scenarios for a prioritized risk-based analysis to provide an effective and credible answer.
Threat Modeling Overview - Definition, Origin, and Use (Art of Espionage)
- Surveying internal readiness is similar to gathering information about an enemy's intent and capabilities.
- Threat models must also account for attack motives, capabilities, vulnerabilities, and available information.
- Threat modeling process complexity lies in expedient analysis and process development, as reconnaissance (information gathering) efforts may be inconclusive.
- Misinformation and an incorrect attack-scenario set can derail threat modeling and mislead defense efforts from creating effective countermeasures.
Threat Modeling Overview - Definition, Origin, and Use (External information sources)
- External sources include application/platform vulnerabilities and attack libraries containing current and past exploits.
Threat Modeling Overview - Definition, Origin, and Use (Attack library)
- Attack libraries consist of exploits required to successfully attack an application and are critical for maintaining flexibility in software products when facing evolving threat scenarios.
- Maintaining threat modeling requires continuous updating. While threat models may initially seem rigid, they should have the flexibility to incorporate the latest threat intelligence.
Threat Modeling Overview - Definition, Origin, and Use (Designing Countermeasures)
- Designing effective countermeasures for software is crucial to differentiate application threat modeling from other traditional efforts.
- Good countermeasures consider not only perceived threats but also potential threat evolution or adaptation to historical forms, thus avoiding a false sense of security.
Threat Modeling Overview - Rationale and Evolution of Security Analysis (Cyber warfare)
- Terms like "cyber warfare", "zero-day botnets" describe complex challenges for information security professionals.
Threat Modeling Overview - Rationale and Evolution of Security Analysis (Environmental Threat Factors)
- Attack motives can be influenced by environmental factors, which impacts attack characteristics such as intensity, sophistication, the possibility of successful exploitation or ability to distort/eliminate forensic evidence.
Threat Modeling Overview - Rationale and Evolution of Security Analysis (Product of the Environment)
- The environment encompasses social, political, economic, belief-based, and financial factors that drive software adversaries.
- Motives such as revenge, spite, espionage and fraud may be influenced by external conditions such as war, layoffs, or economic hardship.
Threat Modeling Overview - Rationale and Evolution of Security Analysis (Environmental factors)
- Environmental factors influence attack windows of opportunity.
- Social, political, environmental, and economic events can create conditions ripe for attacks.
