Security and Maintenance Practices
Keep Your System Patched
Operating system and third party software periodically update for security and enhancement reasons. Some software packages have update managers to help remind you that software updates are available. Don’t wait, take the time to install those updates. Please note that some updates may require a reboot of the system so remember to save and close any open files to protect your data.
BigFix can help you monitor and/or patch your computers. Use this tool to not only report potential system issues, but keep your system patched. Further information can be found on our Patch Management page.
Reboot Your Computer
You should reboot your computer at least once a week if you can. This will ensure that all software updates are downloaded, installed and registered in a system. This is one of the single most important things you can do to help keep your system healthy.
BigFix is a widely adopted cross-platform endpoint management system utilized by private companies, government agencies, and academia. BigFix has a Patch Management module which can identify systems with applications that are out of date and allow system managers to take action to install patches and remediate issues. Berkeley Lab IT has adopted two modes of BigFix, one active the other passive. The Active Mode is recommended for most systems at the Lab, including laptops, desktops, and shared workstations. The Passive Mode is used primarily for monitoring and reporting on system status, software licensing, and asset management. BigFix can be downloaded from the Software Store.
Lastly, BigFix can help automate and manage your asset inventory. Berkeley Lab Property Management and IT have piloted a program to certify the existence of a DOE tagged asset. Any DOE-barcoded system running BigFix and present on the LBL network can be automatically verified for inventory purposes, without the barcode being scanned, see Help IT Automate Your Asset Inventory.
LBNL Cyber Security has defined the Minimum Security Requirements and all computers connected to the Berkeley Lab network must meet these requirements. One requirement is the installation of an antivirus software with automatic updates. Berkeley Lab IT has adopted Sophos as the enterprise solution. Sophos can be downloaded from the Software Store.
Use Multi-Factor Authentication (MFA)
Utilizing at least a two factor authentication process helps protect your online accounts and access to your resources. Berkeley Lab IT recommends everyone adopt MFA. Further details can be found on the MFA site.
Clean Up Your Files
Low disk space can lead to poor system performance and problems with file integrity. Please take the time to clear out any caches, delete data in your downloads folder or temporary folders, and remove any unnecessary data. Remember you have unlimited disk space on Google, use that disk space to your advantage.
Third party software tools claim they can help with system clean up. Do not install CCleaner on Lab computers.
Clear Your Browser Cache
When your browser performance becomes erratic or sluggish start with clearing the cache.
Backup Your Data
Your data is important so don't wait for that disaster. Be proactive and obtain a backup solution that meets your needs. Berkeley Lab IT has adopted Druva inSync as the enterprise backup tool. Druva inSync can be purchased from the Software Store.
Google Drive / Team Drive
Berkeley Lab IT has provided a repository of software from https://software.lbl.gov. Both free and software for purchase can be found on this site. If you are unable to find your software, a request to firstname.lastname@example.org can be submitted. Berkeley Lab IT can also provide access to iOS applications via Apple's Volume Purchase Program (VPP), see Mobile App iOS Purchases.
When working off-site, always utilize Berkeley Lab's VPN (virtual private network). A virtual private network is an encrypted connection over the Internet from your device to a network. Essentially when running VPN, your computer is on Berkeley Lab's secure network and enables you access to restricted resources such as FMS. Cisco VPN software can be downloaded from the Software Store.
Ensure you are designated as the custodian of your computing devices. Property Management guidelines are described here. As the custodian of your computer, you are required to follow all cyber security requirements and protect your computer from loss or theft. If lost or stolen follow Instructions for Reporting Lost, Damaged, Destroyed or Stolen IT Assets.
Hostname Naming Conventions
In order to more easily identify the point of contact for desktop and laptop systems at the Lab, particularly when a cyber security event has been detected and the owner has to be notified, a naming convention for the computer's hostname is being used for standard deployments. Lab staff who do not utilize IT for workstation support should consider adopting the standard themselves.
The standard format is as follows: (LDAP username)-(OS Identifier)(last two digits of the DOE number located on the machine)
Example: cwnelson-x44 or cwnelson-w39
Virtual machine (VM)
- Use the standard format for a Physical Machine, but prefix the OS Identifier with the letter 'v'
- Use the last two digits of the host's DOE number (this is the computer that the VM will be running on)
Example: cwnelson-vt44 for a Windows 10 VM running on a host with the DOE number ending in 44
The current convention allows for for 1 VM of each type of OS on a given workstation.
Operating System identifiers
|Windows 8 or Windows 8.1||E||Eight|
|Mac OS X||M||Mac|
|Red Hat Linux Family||R||RHEL|
|Other Linux Family||L||Linux|
|BSD Unix Family (FreeBSD)||B||Berkeley|
|Virtual Machine||Va||Virtual where a denotes the OS Version, i.e. VT is a virtual Windows 10 system|
