• INTRODUCTION
• TYPES OF NETWORK SECURITY
• ADVANTAGES
• DISADVANTAGES
• CONCLUSION

3. INTRODUCTION:
• Network security consists of the polices, procesess and practices
adopted to prevent, detect and monitor access, misuse, modification,
or denial of a computer network and network-accessible resources.
• Network security involves the authorization of access to data in a
network, which is controlled by the network administrator.
• Users choose or are assigned an ID and password or other
authenticating information that allows them access to information
and programs within their authority.

4. TYPES:
• 1. Firewall
• Firewalls filter the traffic on your network. They work to prevent and block unauthorized internet
traffic.
• 2. Network Segmentation
• Network segmentation divides a network into multiple sections, and each section then acts as their
own individual networks
• 3. Access Control
• Access control gives you the ability to grant or deny access to individual users based on their
responsibilities within your network.
• 4. Remote Access VPN
• A remote access virtual private network (VPN) provides integrity and privacy of information by
utilizing endpoint compliance scanning, multi-factor authentication (MFA), and transmitted data
encryption.

5. TYPES:
• 5. Zero-Trust Network Access (ZTNA)
• The Zero Trust Network grants specific access to an individual user based on the
exact role they play within the network.
• 6. Email Security
• Email security is set up to prevent users from unknowingly providing sensitive
information or allowing access to the network via a malware-infected email.
• 7. Data Loss Prevention (DLP)
• DLP is a network security technology that aids in preventing sensitive information
from accidentally being leaked outside of the network by users.

6. ADVANTAGES:
• Protects against cyber attacks
• Access levels
• Keep your data safe
• Updates are now centralized
• Centrally managed

7. Disadvantages:
• Setup is expensive
• It takes time
• Incompetent administration

8. CONCLUSION:
• Internet connectivity, email and the web, now vital for small business,
pose many risks to computer system and the privacy of the company’s
data.
• The onslaught of viruses, worms compounded with the increasing
problem of spyware, adware, and blended threats continue to attack an
organization’s network through multiple methods.
