Cybersecurity is critical in our connected world. Learn encryption, authentication, secure coding practices, and defense mechanisms to protect systems from threats.
Core Security Principles
Confidentiality: Keep information private and protected from unauthorized access.
Integrity: Ensure data is accurate, complete, and unmodified.
Availability: Systems and data must be accessible when needed.
Authentication: Verify user and system identities.
Authorization: Control what authenticated users can access.
Non-repudiation: Users cannot deny their actions.
Essential Security Measures
Password Management: Strong, unique passwords, regular changes, multi-factor authentication
Software Updates: Keep systems and applications patched
Firewalls: Filter network traffic
Antivirus/Malware: Detect and remove malicious software
Encryption: Protect sensitive data in transit and at rest
Backups: Regular, tested backup procedures
Network Security: VPNs, network segmentation, monitoring
Common Security Threats
Malware: Viruses, worms, trojans, ransomware
Phishing: Social engineering attacks via email
Weak Passwords: Dictionary attacks, brute force
Unpatched Software: Exploitation of known vulnerabilities
Insecure Coding: Buffer overflows, SQL injection
Insider Threats: Unauthorized access by employees
DDoS Attacks: Overwhelming server capacity
