SubjectCyber Security Advisory –“Advisory Regarding Remote Access and Telecommuting”

Ø  Due to outbreak of CORONA COVID-19 Pandemic, many organizations have adopted to “Work from Home” “Remote Access and Telecommuting”

Ø  Unprecedented and multifold increase in usage and dependency on Digital Communications, have also resulted in cyber criminals using this opportunity to target “Users” and “Information Communication Technologies” 

Ø  To mitigate threats arising from “Work from Home / Remote Access and Telecommuting”, SEBI has advised us to ensure that Members / Participants, implement prescribed measures. 

1.       The intermediaries shall have proper remote access policy framework incorporating the specific requirements of accessing the enterprise resources securely located in the data centre from home, using internet connection.

2.       For implementation of the concept of trusted machine as end users, the intermediary shall categorize the machines as official desktops / laptops and accordingly the same may be configured to ensure implementation of solution stack considering the requirements of authorized access.  Official devices shall have appropriate security measures to ensure that the configuration is not tampered with. The intermediary shall ensure that internet connectivity provided on all official devices shall not be used for any purpose other than the use of remote access to data centre resources.

3.       If personal devices (BYOD) are allowed for general functions, then appropriate guidelines should be issued to indicate positive and negative list of applications that are permitted on such devices. Further, these devices should be subject to periodic audit.

4.       The intermediary shall implement the various measures related to Multi-Factor Authentication (MFA) for verification of user access so as to ensure better data confidentiality and accessibility. VPN remote access through MFA shall also be implemented. It is clarified that MFA refers to the use of two or more factors to verify an account holder’s claimed identity.

5.       The intermediary shall ensure that the trusted machine is the only client permitted to access the data centre resources. The intermediary shall ensure that the Virtual Private Network (VPN) remote login is device specific through the binding of the Media Access Control (MAC) address of the device with the IP address to implement appropriate security control measures.

6.       The intermediary shall explore a mechanism for ensuring that the employee using remote access solution is indeed the same person to whom access has been granted and not another employee or unauthorized user. A suitable video-recognition method has to be put in place to ensure that only the intended employee uses the device after logging in through remote access. The intermediary shall implement short session timeouts for better security.  Towards this end, it is suggested that the intermediary may consider running a mandatory monitor on the device that executes:

a.    At random intervals takes a picture with the webcam and uploads the same to the intermediary’s server,

b.   At random intervals pops up and prompts biometric authentication with a timeout period of a few seconds.  If there is a timeout, this is flagged on the intermediary server as a security event.

7.       The intermediary shall ensure that appropriate risk mitigation mechanisms are put in place whenever remote access of data centre resources is permitted for service providers.

8.       Remote access has to be monitored continuously for any abnormal access and appropriate alerts and alarms should be generated to address this breach before the damage is done.  For on-site monitoring, the intermediary shall implement adequate safeguard mechanism such as cameras, security guards, nearby co-workers to reinforce technological activities.

9.       The intermediary shall ensure that the backup, restore and archival functions work seamlessly, particularly if the users have been provided remote access to internal systems.

10.   The intermediary is advised to exercise sound judgement and discretion while applying patches to existing hardware and software and apply only those patches which were necessary and applicable.

11.   The Security Operations Centre (SOC) engine has to be periodically monitored and logs analyzed from a remote location. Alerts and alarms generated should also be analyzed and appropriate decisions should be taken to address the security concerns. The security controls implemented for the Remote Access requirements need to be integrated with the SOC Engine and should become a part of the overall monitoring of the security posture.

12.   The intermediary shall update its incidence response plan in view of the current pandemic.

13.   The intermediary shall implement cyber security advisories received from SEBI, MII, CERT-IN and NCIIPC on a regular basis.

14.   Further, all the guidelines developed and implemented during pandemic situation shall become SOPs post Covid-19 situation for future preparedness. 

Ø  All Member / Participants are advised to take note of above and initiate necessary steps with immediate effect.
