These attacks vary in complexity and intent, but understanding them is key to developing strong defence strategies.


Metrics That Matter

In cybersecurity, metrics help measure performance and identify areas for improvement. Some commonly used metrics include:

MTTC: Mean Time to Contain

MTTA: Mean Time to Acknowledge

MTBF: Mean Time Between Failures

MTTR: Mean Time to Recovery

MTTD: Mean Time to Detect

NHT: Non-Human Traffic

RCA: Root Cause Analysis

CIA: Confidentiality, Integrity, Availability

These metrics guide decision-making and help organisations improve their security posture.


Standards and Frameworks

Compliance with industry standards and frameworks is vital for maintaining cybersecurity. Here are some of the most widely recognised:

ISO: International Organisation for Standardisation

NIST: National Institute of Standards and Technology

GDPR: General Data Protection Regulation

HIPAA: Health Insurance Portability and Accountability Act

PCI-DSS: Payment Card Industry Data Security Standard

SOX: Sarbanes-Oxley Act

DORA: Digital Operational Resilience Act

CSF: Cybersecurity Framework

UCF: Unified Compliance Framework

These frameworks ensure that organisations align with best practices and regulatory requirements.


Certifications for Professionals

Certifications validate the skills and knowledge of cybersecurity professionals. Here are some of the most respected:

CISSP: Certified Information Systems Security Professional

CISM: Certified Information Security Manager

CISA: Certified Information Systems Auditor

GIAC: Global Information Assurance Certification

PICNIC: Problem in Chair, Not in Computer

PEBKAC: Problem Exists Between Keyboard and Chair

WTF: What the Freak

RTFM: Read the Freaking Manual

KISS: Keep It Simple, Stupid

These light-hearted terms remind us to approach challenges with a sense of humour.


Organisations Shaping Cybersecurity

Several organisations play a key role in advancing cybersecurity knowledge and standards:

ISACA: Information Systems Audit and Control Association

ISC²: International Information System Security Certification Consortium

CIISec: Chartered Institute of Information Security

OWASP: Open Web Application Security Project

These organisations drive research, education, and certification in the field.
