Computer systems running vendor-unsupported or end-of-life operating systems are potential security threats to the UAB campus network. Vendors do not provide security patches for unsupported systems, and these unpatched systems can be exploited by attackers. Such exploitations can result in disrupted experiments, corrupted research data and/or completely compromised systems. UABIT reserves the right to disconnect these computers from the campus network to mitigate this data breach risk (see UAB’s Acceptable Use of Computer and Network Resources policy). UAB system administrators are responsible for maintaining the security of all information systems, per the campus Data Protection and Security Policy, which includes updating applications and operating systems.
Windows XP will not be supported after April 2014. Windows versions prior to Windows XP and any version of Mac OS X prior to version 10.6 should be considered unsupported.
The information in this guidance statement applies to all constituents internal to UAB.
We recommend that systems running legacy, unsupported operating systems should not be used. They should be disconnected from the network because of the significant security risk to the university’s network and environment. If the device is critical and cannot be turned off or disconnected, the device should be physically isolated from the university network. If disconnection and/or isolation are not possible, then an exemption and risk acceptance form will need to be completed, signed by the appropriate dean or vice president, and filed with Enterprise Information Security.
Unsupported legacy operating systems:
Windows XP after April 8, 2014
Mac OS X Family
Mac OS 9.x
OS X 10.5 (Leopard)
OS X 10.4 (Tiger)
OS X 10.3 (Panther)
OS X 10.2 (Jaguar)
Ubuntu 11.10 after May 9, 2013
Ubuntu 11.04 and Prior
Ubuntu 10.04.4 LTS
Debian 5.0 (lenny)
Debian 4.0 (etch)
Debian 3.1 (sarge)
Debian 3.0 (woody)
Other Unix OS
AIX prior to 6.1
Solaris prior to 9 (SunOS 5.9)
•Upgrade to Windows 7
A large-scale project is underway to upgrade all university-owned computers on the UAB campus to Windows 7 by April 8, 2014. At that time, Microsoft will cease its support for Windows XP, which has been the operating system primarily used by UAB computers in recent years. As a result of Microsoft no longer supporting this operating system, XP computers will no longer receive security updates. This creates a greater chance of XP computers being infected by viruses or compromised by malware.
This leaves one budget cycle to accomplish funding of this project. Upgrading to Windows 7 for any system needing network connectivity should be completed by April 2014.
• Install IE 9 and the most recently released version of JAVA
We are updating our minimum recommendations for versions of Internet Explorer and Java as UAB systems have improved functionality to support newer browsers and the currently secure version of Java. Internet Explorer 9 and Java (latest release) are recommended for installation on Windows 7 systems.
• Windows 8 not currently recommended for use
As XP fades away, Microsoft has rolled out its newest operating system, Windows 8. The transition from XP has prompted some users to ask why IT doesn’t upgrade to Windows 8 instead of Windows 7. The answer is that Windows 8 is currently not recommended for widespread use in the UAB environment due to the following reasons:
- Currently, not all of UAB’s business systems support Internet Explorer 10, the minimum version of IE used by Windows 8.
- Windows 8 introduces management changes that IT is not yet ready to address.
- Windows 8 is best used on hardware that is specifically made for Windows 8, such as touchscreen displays or touchpads. Other than the touchscreen/touchpad functionality, Windows 8 possesses similar functionality to Windows 7 from an end user’s point of view.
- PGP (UAB’s approved laptop encryption tool) is not supported on Windows 8 laptops. A recommended alternative is Microsoft’s Bitlocker product. (See Bitlocker with windows 8 for more information)
