According to Bharti Airtel, it has upgraded the service-oriented communications (SOC) to a higher threat-level status for a week in the wake of likely cyber-attacks.
In addition, the telco has asked its business enterprise customers to take proactive steps in the wake of growing cyber threats.
The move follows a recent advisory by Indian Computer Emergency Response Team (CERT-In) warning against large scale phishing attacks using COVID-19 as a bait.
To this end, Airtel has urged its customers to take proactive measures such as continuous monitoring of network traffic for all channels, which include email, the internet, and others. It has also asked enterprise customers to enable geo-location monitoring for traffic coming from neighboring countries. The telecom operator has also recommended the installation of updated patches on all assets/webpages, which are accessible via the internet, besides encouraging them to harden server and application infrastructure.
Further, the telco has also advised all employees working from home to update the anti-virus and other software patches.
