Security Guide - Poor Network Configuration

What is the cost of poor network configuration?

In the rush to secure your retail network the temptation is to focus on the obvious network entry points around your system’s perimeter, where sensitive data is exchanged. However, it is also essential to think about what  will happen if you do experience a breach.

Hackers’ tactics

No network can ever be 100% secure from cyber attack. However, a pragmatic retailer will install measures that severely limit the chances of and the impact of a breach. Hackers generally look to infiltrate a soft target first, for example a contractors’ system or in-store Wi-Fi, before moving on to areas with sensitive business data. A common tactic is to target a contractor with a phishing email to steal their log on credentials and then use these to infiltrate a network, for example breaching their POS system.

How to optimise your network configuration

1. Segment your network: Group applications and databases together depending on how sensitive or business critical they are and then keep them together on specific virtual local area networks within your system. Once important functionality is isolated it’s possible to monitor usage more easily and strictly limit traffic.

2. Role-based access: Simply put, you should only grant access to specific parts of your network to colleagues who need it. To achieve this an administrator should either approve or deny access rights based on an employee’s function. For example, only customer service reps should be given access to customer profile information.

3. Apply granular controls: Once your network is segmented you can finely tune your settings so that your system is optimised further. For example, fine tuning a rule that states “Only customer service reps may access customer profiles” to “only customer reps that handle sales or refunds may access customer profile information”.
