General Security Issues
Studentnet Recommended Browsers
Outdated browsers are one of the major security risks on the Internet. It is
essential to keep your browser up-to-date, as that is the only genuine
protection against such vulnerabilities. See
recommended versions of popular browsers supported by Studentnet.
The POODLE Attack
An exploit directed against out-of-date browsers is the POODLE attack, which exploits SSLv3, used in older
browsers. TLS (Transport Layer Security), implemented in recent browsers,
provides protection. More information on POODLE.
The Shellshock bash Vulnerability
Wikipedia for more information.
Shellshock is a family of major security bugs in the widely used Unix bash
shell, first disclosed on 24 September 2014. Software such as web servers use
bash to process commands. Attackers can use vulnerable versions of bash to
execute arbitrary commands and gain unauthorized access to systems. By 25
September botnets based on Shellshock-compromised computers were already being
used for distributed denial-of-service attacks and vulnerability scanning.
