PC Security is the practice of safeguarding a personal computer’s hardware, software, and data from unauthorized access, damage, or theft. It ensures the system operates correctly, preserves your privacy, and keeps your files intact. In today’s digital landscape, effective defense relies on the “CIA Triad”: keeping data private (Confidentiality), ensuring data is not modified maliciously (Integrity), and maintaining system access (Availability). 🛡️ Core Defense Pillars
To secure a PC effectively, you must understand the foundational tools that build a virtual wall around your data:
Antivirus Software: Monitors, detects, and deletes malicious programs like viruses, ransomware, trojans, and spyware. Operating systems often feature robust built-in protection, such as Microsoft’s Windows Defender.
Firewalls: Acts as a virtual barrier that controls incoming and outgoing network traffic based on strict security rules.
User Account Control: Restricts programs from executing administrator-level changes without your direct permission.
Tamper Protection: Prevents malicious apps from covertly disabling your active security settings. ⚠️ Critical Security Threats
