It depends on what services you are running on your server, what is the server configuration, etc. 1) Maintain a log of what is going on and watch it regularly. 2) Have only required services running, disable all other services. 3) Use secure services like SFTP instead of plain text FTP, and https instead of http if possible and if necessary, so that MITM attacks are minimized. 4) Provide authentication in whatever service you are providing. 5) Have proper and secure input processing wherever possible (to prevent SQLi and XSS, etc). 6) Use firewalls and make sure you are secure against DOS and DDOS. There are a lot more but it depends on what services you are providing. Please be specific and provide the necessary data. -- Cheers, Hrishikesh Murali _______________________________________________ To unsubscribe, email [email protected] with "unsubscribe <password> <address>" in the subject or body of the message. http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
