The document outlines essential practices for network security management, emphasizing the importance of firewalls, network segmentation, and data encryption. It also highlights the need for robust backup processes and a clear incident response strategy to ensure preparedness against potential breaches. Regular testing and updates of these measures are necessary to maintain their effectiveness.

1. Firewalls: First Line of
Defense
Employ firewalls to screen inbound
and outbound network traffic.
Configure firewalls to permit
essential traffic and block
unauthorized activities.
Leverage advanced features like
deep packet inspection and
intrusion prevention.
SECURING YOUR NETWORK: EFFECTIVE
PRACTICES FOR NETWORK SECURITY
MANAGEMENT
Network Segmentation
Enhances Security
Enhance security through network
segmentation into smaller zones.
Apply distinct security measures
based on data importance.
Mitigate breach impact and prevent
lateral attacker movement.
Backup and Disaster
Recovery Planning
Establish robust backup and
recovery processes.
Regularly backup critical data and
systems.
Validate the efficacy of the
restoration process.
Data Encryption for
Protection
Ensure data security through
encryption at rest and in transit.
Utilize HTTPS for online traffic and
VPNs for secure public network
communication.
Incident Response
Preparedness
Develop a clear incident response
strategy.
Outline stages from detection to
recovery and communication.
Regularly test and refine the plan
for ongoing relevance.
