2. About Key Size Analysis of Brute Force Attack and CyberSecurity Malaysia Key Size Analysis of Brute Force Attack is a fast password cracker, currently available for many flavors of Unix, Windows, DOS, BeOS, and OpenVMS. Its primary purpose is to detect weak Unix passwords. CyberSecurity Malaysia began its operation as the Malaysian Computer Emergency Response Team (MyCERT) in 1997. In 1998, it became the National ICT Security & Emergency Response Centre (NISER) and by 2007, NISER underwent another transformation and was renamed CyberSecurity Malaysia. With a new mandate, CyberSecurity Malaysia is positioned as the national cyber security specialist under the Ministry of Science, Technology and Innovation (MOSTI). www.mimos.my© 2010 MIMOS Berhad.
