SPIRIT BEHAVIOURS

Create the Future, Get it done Together

At VOIS, we always establish robust firewall rules and network security that prevent unauthorised access to our network. We inspect incoming and outgoing traffic using security rules to identify and block threats.

Challenges and Solutions

Challenges

Our firewall rule base used to grow significantly with added complexity and inefficiency. Due to the complexity of the rule base, there has always been a concern that security gaps may exist, allowing potential threats to go undetected and unauthorised access to critical systems.

Solutions

After assessing existing firewall and security policies, we identified redundant rules and conducted risk assessments to eliminate these rules and remove complexity. We continuously monitored the network for security incidents or policy violations during change. We maintained up-to-date documentation of the rule base with changes and generated reports that provided insights into rule-based performance, compliance status, and security postures. We analysed the rule base to identify redundant rules, rule owners, and stakeholders within the organisation to make them aware of the activity. We also conducted a risk assessment to determine the impact of rule changes on network security. We deactivated the number of access lists under clean-up activity with all change management processes.

Value and Impact

15K

Removed and deactivated more than 15K rules from the firewall without an incident.

Enhanced our security postures, firewall performance, compliance, and risk mitigation.

Intelligent Dispatching Tool - R1

Our Incident Management teams partnered with Vodafone Germany and built a database-to-database connection as a web-based application for fast, automated dispatching techniques, eliminating manual operations where there were delays. Our Intelligent Dispatching (DB) tool is connected to remedy any issues through Amazon Web Services (AWS) data migration services to get all relevant tickets and then pass those tickets to our logic and dispatching algorithm.

Empire (Apple Launch – 2023) - Data & Analytics

With the support of our teams in India, we launched 'Empire' for Vodafone UK. Historically, iPhone launches have been regarded highly due to the revenue generation and direct customer impact. Our operations team wanted to ensure the best possible support during the event. Our operations team implemented an alerting system using AppDynamics for business transaction monitoring, so any degradation in any of the business services will raise alerts that will invoke the incident management process.
