Network Security
Protecting business networks through structured security controls, secure connectivity and practical network defence.
Overview
Network security is the foundation of a reliable and secure IT environment. Electroluxss provides practical network security support designed to help businesses protect network infrastructure, control access, secure communications and reduce security risks.
Our approach focuses on understanding the existing network environment, identifying security and connectivity requirements, investigating problems and supporting practical solutions that improve reliability and security.
What Network Security Covers
Firewall Security
Configuration and administration of firewall environments, including security rules, access controls, NAT policies, traffic inspection and policy review.
Access Control
Supporting appropriate control over which users, devices, applications and network segments can communicate with protected resources.
Network Segmentation
Supporting logical separation of networks to help control communication between different network environments and reduce unnecessary exposure.
VPN Security
Support for secure remote-access and site-to-site connectivity, including VPN troubleshooting, configuration review and traffic-related issues.
NAT Configuration
Support for Network Address Translation requirements and investigation of connectivity problems caused by NAT policies.
Security Policies
Reviewing and troubleshooting firewall and network security policies to help ensure permitted traffic is appropriately controlled.
Key Network Security Areas
Firewall Administration
Managing and reviewing firewall-related configurations and security controls.
Security Policy Management
Supporting policy review, troubleshooting and security rule analysis.
Network Traffic Analysis
Investigating network traffic patterns and identifying unexpected behaviour.
Firewall Log Analysis
Reviewing relevant logs to help investigate blocked, allowed or unusual traffic.
Common Network Security Issues We Help Investigate
- Users unable to access required applications
- VPN connections failing or disconnecting
- Traffic being unexpectedly blocked
- Incorrect or conflicting firewall rules
- NAT-related connectivity problems
- Communication between network segments not working
- Unexpected network traffic
- Firewall policy conflicts
- Connectivity problems following configuration changes
- Difficulty identifying the source of network traffic
Our Approach
We first understand the network environment and reported requirement. Relevant firewall policies, network paths, traffic behaviour, logs and configurations can then be examined to identify the likely cause. Appropriate troubleshooting or configuration actions are supported, followed by validation of expected network behaviour.
Technologies & Areas
Network security work can involve a range of security and networking technologies and environments, including:
- Palo Alto Networks
- Check Point
- Cisco
- Fortinet
- VPN technologies
- TCP/IP networking
- VLANs
- Routing and switching
- DNS and DHCP
- Network monitoring and packet analysis
Why Network Security Matters
A well-managed network security environment can help organisations protect important network resources, control unnecessary access, improve visibility into network traffic and reduce configuration-related risks.
Effective network security can also support secure remote connectivity, investigation of unusual network behaviour and more reliable business connectivity.
