INTRODUCTION TO NETWORK SECURITY
1.1Importance of network security in modern infrastructure
Threat landscape: types of attacks, actors, and motivations
Confidentiality, Integrity, and Availability (CIA triad)
Authentication, Authorization, and Accountability (AAA)
Security Policies and Standards
2 THREATS AND VULNURABILITIES
Introduction -Threats and Vulnerabilities
DoS/DDoS, IP spoofing
ARP poisoning, DNS spoofing, and MAC flooding
Protocol-specific vulnerabilities (e.g., DNS cache poisoning)
Vulnerability scanning and patch management
Tools: Nessus, OpenVAS
NETWORK SECURITY DEVICES AND TECHNOLOGIES
Types (stateful, stateless, application-layer firewalls)
Configuring firewall rules and policies
Difference between IDS and IPS
Network-based and Host-based IDS
Types of VPNs (site-to-site, remote access)
NAC(Network Access Control) concepts and implementation
NETWORK TRAFFIC ANALYSIS
Importance of packet analysis in security
Importance of packet analysis in security
Packet capture and packet analysis tools (e.g., Wireshark, tcpdump)
Network baselining, identifying anomalies
Protocol analysis, flow analysis
Syslog, NetFlow, SIEM (Splunk, Elastic Stack)
Analyzing and interpreting logs
CRYPTOGRAPHY AND NETWORK SECURITY
Fundamental of Cryptography
Symmetric and Asymmetric Cryptography
Cryptography Algorithms and Numericals
Hash functions, digital signatures, certificates
Public Key Infrastructure (PKI) concepts
SSL/TLS protocols
Encrypting traffic over network protocols
SSH, and HTTPS
NETWORK SECURITY ANALYSIS AND FORENSIC
Incident handling and response lifecycle
Evidence collection, preservation, and chain of custody
Log analysis and event correlation
Deep packet inspection (DPI) and identifying patterns
SECURING WIRELESS NETWORKS
Wireless protocols and standards (WEP, WPA, WPA2, WPA3)
Wireless vulnerabilities and attacks (e.g., deauthentication attacks)
Implementing secure authentication (e.g., EAP, 802.1X)
Securing wireless access points and network segmentation
ADVANCED TOPICS IN NETWORK SECURITY
Core concepts and design principles
Implementing a zero-trust network model
Cloud-specific threats and best practices
Cloud network security tools and configurations
Threat intelligence and proactive defense
