Modern Security Landscape Explained in Simple Terms

Security technologies form the backbone of modern IT, covering databases, networks, endpoints, cloud, and identities to protect organizations against evolving cyber threats.

• Database Security → Protects databases with firewalls, encryption (TDE), and monitoring tools to stop data leaks.
• Network Security → Shields your network using firewalls (NGFW), WAF (for websites), IDS/IPS (attack detection/prevention), and DDoS protection.
• Endpoint Security → Secures laptops, mobiles, and servers with antivirus (EPP), advanced detection (EDR), mobile management (MDM).
• Cloud Security → Protects cloud apps and services with monitoring (CSPM), workload protection (CWPP), and secure access (SASE).
• Identity & Access → Ensures only the right people get in using IAM (identity management), PAM (admin control), and MFA (extra login security).
• Application Security → Keeps software safe by testing for bugs (SAST/DAST), protecting APIs, and blocking attacks during runtime (RASP).
• Threat Monitoring → Detects and responds to threats using SIEM (log analysis), SOAR (automation), and UEBA (user behavior analytics).
• Data Protection → Keeps data safe with encryption keys (HSM), rights management (IRM), and backup + disaster recovery.
• OT/IoT Security → Protects industrial systems (SCADA, ICS) and IoT devices (sensors, gateways).
• Zero Trust & Perimeter-less → Security model that says “Never trust, always verify” using ZTNA and SDP for secure access.

Above layered security solutions create a holistic defense strategy—ensuring data, applications, and systems remain resilient in today’s digital-first world.
