Explore the distinctions between cyber security and digital forensics, their overlapping aspects, and the career opportunities they offer.
Working in cyber security and digital forensics is like playing in attack and defence roles for the same football team. Both disciplines work to safeguard information, networks, programs and other digital assets. But while cyber security is proactive, digital forensics is reactive.
Cyber security is developing, implementing and auditing security mechanisms that protect information. Working in the field involves predicting and detecting vulnerabilities to prevent cyberattacks before they happen.
Professionals working in this area design secure systems using programming, encryption and security tools. Creating security policies and governance and delivering relevant staff training are common non-digital based elements of cyber security.
Digital forensics is the gathering, analysing and retrieving of electronic data, assets, and evidence. The goal is often to identify the individuals behind and mechanisms used for hacking or malware and sources of data breaches.
Digital forensics can also be used to retrieve other evidence of crime. During evidence gathering, legal protocols and regulations must be observed. Digital forensics investigators can write reports and appear as expert witnesses in court. The field includes detection across different types of digital devices and systems including computer forensics, mobile forensics, database forensics, malware and incident response.
Cyber security and digital forensics are complementary elements of information security. Both involve identifying vulnerabilities and weaknesses. However, the scope of the roles is different and most simply defined as prevention versus response. After a data breach, digital forensic detective work can inform improvements to safeguard information. Cyber security and digital forensic roles may come into conflict if a digital forensics investigator identifies security system failings.
Studying digital forensics alongside cyber security gives broader knowledge of information security issues. Students gain a deeper understanding of how the disciplines overlap and work together and are able to pursue cybersecurity or digital forensics specialisms. Graduates may also opt to move into overarching or related roles within information technology.
If you're exploring how to become a digital investigator or forensic analyst, you should know these are roles in a high-growth sector. Knowledge of these areas is valued and in demand.
