Network Security

Ensure that firewalls are deployed at the network perimeter and within internal segments to monitor and filter incoming and outgoing traffic according to
predefined security rules.
By analyzing network traffic for suspicious patterns or known attack signatures, intrusion detection and prevention systems (IDPS) can detect, log, and prevent malicious activity.
Implement virtual private networks (VPN) to ensure secure remote access for users, which encrypts traffic between endpoints and the network in order to protect the integrity and privacy of data.
To limit access, minimize attack surfaces, and protect against potential security breaches, segment the network into isolated zones (e.g., DMZ, internal network, guest network).
Implement strict access control policies (Role-Based Access Control, Least  Privilege) to ensure that only authorized users and devices are able to access sensitive network resources.
Protect endpoints by deploying endpoint protection tools (e.g., antivirus, anti- malware) to prevent threats from infiltrating the network.
Ensure the confidentiality and integrity of sensitive data while in transit and at rest by implementing encryption protocols (e.g., SSL/TLS, IPsec).
The use of multi-factor authentication (MFA) is an additional layer of security to verify the identity of users beyond passwords for critical network access.
Monitoring and logging of security activities: Consistently monitor traffic on the network and forensically analyze log entries to detect anomalies, perform forensic analysis, and ensure compliance with security policies.
Plan for identifying, containing, and mitigating security breaches to minimize the impact of potential attacks through the development and maintenance of a comprehensive incident response plan.
