EthicalHat’s Network Redesign Service is geared towards optimizing your network security and performance by:
- Identifying critical network assets and systems
- Segmenting the network
- Using effective monitoring and incident prevention tools
- Using SIEM tools for aggregating event logs and identifying anomalies
- Always using the Principle of Least Privilege to prevent unauthorized access
An organization’s critical assets include both the sensitive data and information stored in its systems, and the system hardware itself. Identifying and classifying these assets is the first step towards formulating an effective network redesign plan.
Segmenting the network involves physically and logically separating internet-facing systems from internal systems that store and use high-value data. Breaking up the network into multiple different layers ensures that malicious actors who gain an entry into your network cannot move laterally beyond a point and don’t get access to sensitive information.
As part of our Network Redesign Service, we help you plan and implement your network segmentation for maximum security. We can also tweak your network security architecture on an ongoing basis to make sure your IT assets and information remain secure as the threat landscape evolves, and that you continue to meet all your compliance needs.
We use a range of intrusion detection, intrusion prevention and data loss prevention tools to defend your systems and data against cyber attacks. If you already have the tools in place, we help you configure these for increased security. Additionally, we leverage some of the best Security Information and Event Management (SIEM) tools in the industry to help you aggregate logs, identify malicious activity, and remediate vulnerabilities in your IT environment.
One of the most important Network Redesign services were provide is hardening routers and switches through secure configuration and more effective use of their security features. We help you identify the networking devices that are most critical for security and must be secured as a priority. These include internet connected routers at the network border, switches in the “demilitarized zone” or DMZ, and routers and switches used for packet filtering.
We also help with VLAN network segmentation both for increased security and improved performance. Segmenting the VLAN network blocks unauthorized access and significantly reduces packet-sniffing attempts, in addition to facilitating efficient bandwidth use and keeping out inessential traffic.
Finally, in all our Network Redesign projects, we help clients effectively implement the Principle of Least Privilege. This involves preventing privilege escalation attempts and low-level user account compromise by properly configuring user accounts, networks, databases and applications.
