Internet Security Problems. The Computer Emergency Response Team (CERT), responsible for monitoring security attacks on the Internet, recently issued a warning that internet security incidents are on the rise. Since February, the number of automated attacks has grown from seven to thirty‐seven, involving thousands of hosts. Weaknesses in Unix operating systems were partially responsible for the break‐ins, and users were strongly urged to change their passwords. The National Institute of Standards and Technology (NIST) is planning a “TCP/IP Firewalls Initiative” to offer guidance on Internet connection and security design.
