🔐 Cybersecurity & Ethical Hacking
What is Cybersecurity & Ethical Hacking?
Cybersecurity is the practice of protecting systems, networks, and data from digital attacks. It ensures confidentiality, integrity, and availability of information.
Ethical Hacking is the authorized practice of probing systems for vulnerabilities to strengthen security. Ethical hackers (or penetration testers) use the same techniques as malicious hackers but with permission, to help organizations defend against threats.
A Cybersecurity Professional / Ethical Hacker is responsible for:
➤ Identifying vulnerabilities in systems and networks
➤ Performing penetration tests and security audits
➤ Monitoring and responding to cyber threats
➤ Implementing firewalls, encryption, and secure protocols
➤ Training teams on security best practices
➤ Ensuring compliance with standards like ISO, GDPR, HIPAA
Domains of Cybersecurity
1. Network Security
Protecting internal/external networks from intrusions.
Tools: Wireshark, Nmap, Snort
2. Application Security
Securing software and web apps against exploits.
Tools: Burp Suite, OWASP ZAP
3. Cloud Security
Protecting cloud platforms (AWS, Azure, GCP).
Tools: Prisma Cloud, AWS Security Hub
4. Endpoint Security
Securing devices like laptops, phones, IoT.
Tools: Antivirus, EDR (CrowdStrike, SentinelOne)
5. Cryptography
Encrypting sensitive data for confidentiality.
Tools: OpenSSL, GPG
6. Incident Response & Forensics
Detecting, analyzing, and responding to breaches.
Tools: Splunk, ELK Stack, Autopsy
