4. Components of Security Architecture
• Spheres of Security
– Shows how information is under attack from variety of sources.
• Levels of Control
– Safeguards provide three levels of control.
• Defense in Depth
– Shows the layered implementation of security.
• Security Perimeter
– It defines boundary between outer limit of organization and the
outside world.

6. Spheres of Security
• Foundation of the security framework,
• Info Sec is designed using three layers
Presented By, K.Senthil Kumar,Asst Professor,Sri Eshwar College of Engineering

7. Levels of Control
• Managerial Controls
– Set the direction and scope of the security process and provides
detailed instruction for its conduct
• Operational Controls
– Address personnel security, physical security and protection of
production inputs and outputs
• Technical Controls
– It protects information assets.
– Examples – Logical access control  identification, authentication,
authorization, accountability, cryptography.

8. Defense in Depth
• Defense in depth is called as layered
implementation of security.
– Policy prepares organization to handle threats
– Training avoids attack enabled by ignorance.
– Technology detects attack and provide reaction.
– Redundancy is important in any implementation

9. Security Perimeter
• A security perimeter is the level of security that
protects all internal systems from outside attacks.
• Components of Perimeters are
– Firewalls
– DMZ
– Proxy Servers
– IDPS

10. Firewalls
• Firewalls is a computing device or specially
configured computer
• It allows or prevent access to defined area
based on rules.
• It is placed on security perimeter

13. Intrusion Detection and Prevention System
• IDPS detects unauthorized activities
within the inner network.
– Host Based IDPS
– Network Based IDPS
