When contacted, Sify’s Regional Manager (North) Punit Sharma claimed Sify has an ‘‘online monitoring system’’. The ISP’s Delhi-based Chief Communications Officer David Appasamy said in an e-mail interview: ‘‘Sify has implemented Intrusion Detection Systems, Firewalls and other mechanisms in the network and has a Security Task force which constantly monitors unnecessary activity on the network and takes appropriate action’’.ids , firewalls are all good news but incapable of monitoring activity on local area segments . these are devices meant for usually ingress filtering and rarely egress except for some state based firewalls . for the network monitoring to be working one needs to install hardware like a managable switch , have ACL 's and run other ids which can monitor sniffing activity at the CTO level which seems highly improbable . you are still better off relying on yourself and get that firewall installed , run an antivirus and install a good anti-spyware , malware software . leaving things like your privacy in sify's hand is a joke .
