Effective cybersecurity relies on a combination of tools, technologies, and practices. Explore some of the core mechanisms used to protect against cyber threats.
Firewalls
Network security systems monitoring and controlling traffic based on rules. Act as barriers between trusted and untrusted networks.
Antivirus/Anti-malware
Detects, prevents, and removes malicious software using signature-based, heuristic, and behavioral analysis.
Encryption & Hashing
Converts info into code (encryption) or creates unique strings for integrity (hashing). Includes Symmetric/Asymmetric keys, Digital Signatures.
IDS/IPS
Intrusion Detection Systems (IDS) monitor and alert. Intrusion Prevention Systems (IPS) also block detected intrusions.
Authentication & Access Control
Verifying identity (passwords, MFA, biometrics) and restricting resource access based on "Least Privilege" principle.
VPNs (Virtual Private Networks)
Create secure, encrypted connections over public networks for private access and enhanced online privacy.
Core Security Practices & Tools
Security Best Practices
- Patch Management: Regularly applying software updates and security patches to fix known vulnerabilities. Critical as most attacks exploit known flaws.
- Data Backup & Disaster Recovery Plan (DRP): Creating data copies and having a plan to restore IT systems after a disruptive event. Crucial for business continuity.
- Secure Coding Practices: Developing software with security built-in from the start to minimize vulnerabilities like SQL injection and XSS.
- Cyber Hygiene & User Awareness Training: Basic user practices (strong passwords, cautious habits) and educating users about threats. The human factor is often the weakest link.
Security Information and Event Management (SIEM)
A centralized platform that collects, aggregates, and analyzes security-related data (logs, events) from various sources across an organization's IT infrastructure. It provides real-time visibility into security events, helps detect threats, and facilitates incident response.
India has developed a multi-layered institutional and policy framework to address cybersecurity threats. Key components are outlined below.
