- Servers did not facilitate outgoing calls;
- Received an exorbitant telecom bill of Rs. 50 lakhs;
CHALLENGES
- Telecom Service Provider was forcing the NGO to pay the amount;

STRATEGY
- Investigations were performed on servers;
- Servers were found to be compromised;
- System hardening was ensured;
- Firewall was properly configured;
- Public Network PRI Line Servers were secured;
IMPACT
