Security frameworks & governance
The playbooks organisations use to decide what to protect and how.
What it is
A security framework is a structured set of good practices so organisations don't have to invent security from scratch. The NIST Cybersecurity Framework groups work into six functions: Govern, Identify, Protect, Detect, Respond and Recover. ISO 27001 is an international standard for running an information security management system. MITRE ATT&CK catalogues how real attackers behave, so defenders can check their coverage. Governance is the layer above the tools: policies, risk decisions and making sure rules are actually followed. Compliance (meeting rules like GDPR, HIPAA or PCI DSS) overlaps with security but isn't the same thing: you can be compliant and still insecure.

The NIST CSF in practice
When a company says it is 'mapping to the NIST CSF', it means checking each function: do we know what we have (Identify)? Can we stop attacks (Protect) and spot them (Detect)? Do we have a plan to Respond and Recover? The newest version added Govern to put risk ownership at the centre.

How defenders stop it
- Pick a framework that fits your size and sector rather than starting from nothing
- Use MITRE ATT&CK to find gaps in what you can detect
- Treat compliance as a floor, not the goal: meeting rules is not the same as being secure
- Write policies people can actually follow, and review them

1. What are the six functions of the NIST Cybersecurity Framework?
- Govern, Identify, Protect, Detect, Respond, Recover
- Plan, Do, Check, Act, Review, Repeat
- Scan, Patch, Monitor, Alert, Block, Report
- Confidentiality, Integrity, Availability, Audit, Comply, Insure
Show answer
Govern, Identify, Protect, Detect, Respond, Recover. The NIST CSF groups work into Govern, Identify, Protect, Detect, Respond and Recover.
2. Which statement about compliance is true?
- You can be compliant and still insecure
- Compliance guarantees security
- Compliance only applies to governments
- Compliance replaces the need for a framework
Show answer
You can be compliant and still insecure. Meeting rules like PCI DSS is a minimum bar; it doesn't guarantee you're actually secure.
3. What is MITRE ATT&CK mainly used for?
- Mapping real attacker tactics so defenders can find gaps
- Encrypting data at rest
- Assigning IP addresses
- Writing privacy policies
Show answer
Mapping real attacker tactics so defenders can find gaps. ATT&CK catalogues how attackers behave, so teams can check what they would and wouldn't detect.
