BSI 200-3 covers risk analysis based on IT-Grundschutz. It's needed when the standard Grundschutz measures aren't sufficient — for assets with high security requirements or unusual scenarios.
* The BSI 200-3 process; a supplementary risk analysis kicks in only where standard Gru...
Q What are the three pillars of information security, and why does relying on just one fail?
Information security stands on three pillars — technology, processes, and people — and it is only as strong as the weakest of them; a firewall means nothing if the process is undefined or an employee clicks the phishing link.
* Information security rests on three complementary p...
Q In a "Value at Risk" view of cyber risk, which three high-level factors combine to determine the ris...
Vulnerability, Assets, and Profile of Attacker — together they answer who/why, what/how, and where/when an attack happens.
* Value at Risk — three factors combine: Vulnerability (where/when), Assets (what/how), Attacker Profile (who/why). *
Value at Risk decomposes cyber risk in...
Q In the second modelling step you "identify your high-value asset." What kinds of things count as hig...
High-value assets are the systems and processes that produce value or money — e.g. a customer database, web portal, payment process, reconciliation, a SWIFT gateway, the production/operational-technology (OT) process, an ERP or HR system, or logistic planning.
The point is to fin...
Q In step 6 you "determine current and desired-state measures." How does referencing MITRE mitigation...
Listing concrete, catalogued mitigations — like network segmentation (M1030) or multi-factor authentication (M1032) — turns vague intentions into specific, traceable controls mapped to the threats they counter.
Example improvements from the worked exercise include segmenting the...
Q What is BSI Standard 100-4 and what are the phases of its emergency management lifecycle?
BSI 100-4 covers emergency management (business continuity), providing a methodology for establishing and maintaining an organization-wide emergency management system.
Key characteristics:
Methodology for business continuity management (BCM)
Creates a standalone management syste...
Q A "Value at Risk" analysis is meant to answer who/why, what/how, and where/when about a cyberattack....
Who and why = threat types and their motivations; what and how = the type and technical sophistication of the attack; where and when = the organization's vulnerability measured against a cyber-resilience maturity level.
"Who and why" addresses target attractiveness and threat mot...
Q What is a "Threat Matrix" of adversary versus intent, and what does each axis represent?
A Threat Matrix maps types of adversary (rows) against types of target (columns) and fills each cell with the intent — the kind of harm that actor would pursue against that target.
* Threat Matrix — adversary types (rows) × target groups (columns); each cell names the intent, co...
Q What is the purpose of comparing a "current state" against a "desired state" for each security measu...
The gap between where a control is today (current) and where it needs to be (desired) is exactly the work the improvement roadmap must fund — it makes the investment case concrete and prioritizable.
For each measure (segmentation, access management, XDR monitoring, incident respo...
Q What is the relationship between ISO 27001 certification and BSI IT-Grundschutz?
An ISO 27001 certificate based on IT-Grundschutz includes both an ISMS audit and a verification of concrete IT security measures — making it more rigorous than a standard ISO 27001 certification.
ISO 27001 on IT-Grundschutz:
Covers both the ISMS (management system) and the concr...
