Network security aims to protect networks from unauthorized access, data loss, and viruses. There are two main types of network security: physical security and logical security. Key goals of network security are confidentiality, integrity, and availability of data. While network security safeguards data through encryption, firewalls, and anti-virus software, it also has disadvantages such as cost and potential for a false sense of security.

NETWORK SECURITY
CONTENTS Introduction Types of Network Security Security from Goals of Network Security Importance of Security Preventive steps for network security Way to secure data Advantages Disadvantages Scopes of improvement Conclusion
INTRODUCTION Network The networks are comprised of “nodes”, which are “client” terminals and one or more “server” and “host” computer Security Security is the condition of being protected against or loss. In the general case is the concept similar to safety Network Security Controlling systems to prevent any accidental or intentional data loss
TYPES OF NETWORK SECURITY There are two types of network security 1. Physical Security 2. Logical Security
SECURITY FROM We need Security from • Unauthorized access • Viruses • Hackers
GOALS OF NETWORK SECURITY  Confidentiality  Integrity  Availability
IMPORTANCE OF SECURITY  Huge amount of internet access.  Huge amount of personal, commercial, governmental, and military information.  The vast connectivity also poses monumental risks.
PREVENTIVE STEPS FOR NETWORK SECURITY  Establishing a plan  Know your attackers  Determine the pain of thresholds  Understand the sources of risk
WAY TO SECURE DATA  Encryption  Anti-virus Packages  Firewall
ADVANTAGES  Network Security Safeguard our data from 1.Hackers 2.unauthorized access 3.Viruses  Network Security makes our system robust.  Network Security makes the system reliable.
DISADVANTAGES  Cost can be a big factor  False sense of Security
SCOPES OF IMPROVEMENT  Cost  Difficult to implement  Difficult to identify potential threads  Compatibility: between two systems  Maintenance
CONCLUSION  Network Security is very important for any organization  It plays a major role in protecting the network from any type of intrusions, virus attacks, spyware etc.
