Cybersecurity
Cybersecurity
Cybersecurity protects systems, networks, applications and data from unauthorised access, disruption and misuse. Strong security combines people, processes and technology.
Tools and technologies
- OWASP ZAP
- Burp Suite Community Edition
- Wireshark
- Nmap for authorised testing
- Wazuh
- OpenVAS / Greenbone
- Multi-factor authentication
- Backups and endpoint protection
Practical examples
- A WordPress site security checklist covering updates, least privilege and backups.
- A log-monitoring dashboard that flags repeated failed logins.
- An authorised test of a deliberately vulnerable lab application.
Application areas
- Secure web and mobile applications
- Incident response
- Network defence
- Cloud security
- Identity and access management
- Security awareness
Suggested hands-on project
Mini project: create a defensive checklist for a test WordPress site, enable MFA, review user roles, update software, configure backups and verify that a restore works. Test only systems you own or have written permission to assess.
A typical workflow
Identify assets and risks → apply secure configuration → monitor logs → test within authorised scope → patch and recover → document incidents → improve controls continuously.
How to get started
Choose one small, measurable problem, build a prototype with sample data, document assumptions, test common failure cases, and collect feedback before expanding it.
Responsible use: Only scan or test systems with explicit permission. Do not use security tools to access accounts, disrupt services, steal data or bypass controls.
