Foundations and Evolution of Cybersecurity
📌 Cybersecurity is the effort to protect systems, networks, and data from illegal actions like use, disclosure, modification, disruption, or destruction.
💾 The concept dates back to the early 1970s with Thomas's creation of the program "Creeper," which moved across the ARPANET.
🛡️ The first commercial antivirus software, such as VirusScan by John McAfee, emerged in 1987.

Common Cyber Attack Types
👾 Malware (including viruses, Trojan horses, and worms) is designed to damage systems or steal data.
🎣 Phishing involves deceptive techniques used to trick victims into revealing personal information.
🔒 Ransomware attacks encrypt data and demand payment (ransom) for its return; this was highlighted in the attack on Indonesia's national temporary data center.
💣 Other major threats include SQL Injection (exploiting database vulnerabilities) and Denial of Service (DoS) attacks (overwhelming services with traffic).

Types of Cybersecurity Strategies
🌐 Network Security focuses on protecting computer networks from unauthorized access, using tools like firewalls to control traffic.
💻 Application Security concentrates on protecting software from vulnerabilities, often involving penetration testing (APT).
☁️ Cloud Security specifically safeguards data and systems within cloud computing environments through strict access controls.
⚙️ Operational Security ensures that people, processes, and technology work together effectively to secure infrastructure, often involving regular system audits.

The Cybersecurity Response Process
🚨 The process is layered, beginning with detection of suspicious activity and immediate prevention by blocking malicious traffic.
🛠️ Following analysis, containment involves isolating infected devices to stop the spread, often followed by patching software vulnerabilities.
🔄 Recovery focuses on restoring systems to a pre-attack state, typically by restoring from data backups or reinstalling software.
🔍 The final stage involves investigation and reporting (forensic analysis) to understand the attack source and document findings to prevent future similar incidents.

Key Points & Insights
➡️ With 221 million internet users in Indonesia in 2024, the risk of cyber threats is continually rising alongside digitalization.
➡️ Effective cybersecurity requires layered mechanisms across detection, prevention, containment, and recovery phases.
➡️ Individuals and organizations must continuously update their knowledge about evolving online threats, not just relying on technological defenses.
