HP 15 6 Elitebook 850 G2 Notebook User Manual

							Managing a Computer Setup DriveLock password (select products only)
CAUTION:To prevent a DriveLock-protected hard drive from becoming permanently unusable, record the
DriveLock user password and the DriveLock master password in a safe place away from your computer. If you
forget both DriveLock passwords, the hard drive will be permanently locked and can no longer be used.
DriveLock protection prevents unauthorized access to the contents of a hard drive. DriveLock can be applied
only to the internal hard drive(s) of the computer. After DriveLock protection is applied to a drive, a password
must be entered to access the drive. The drive must be inserted into the computer or an advanced port
replicator in order for it to be accessed by the DriveLock passwords.
To apply DriveLock protection to an internal hard drive, a user password and a master password must be set
in Computer Setup. Note the following considerations about using DriveLock protection:
●
After DriveLock protection is applied to a hard drive, the hard drive can be accessed only by entering
either the user password or the master password.
●
The owner of the user password should be the day-to-day user of the protected hard drive. The owner
of the master password may be either a system administrator or the day-to-day user.
●
The user password and the master password can be identical.
●
You can delete a user password or master password only by removing DriveLock protection from the
drive.
NOTE:For select products, a BIOS administrator password must be set before you can access the
DriveLock features.

Using antivirus software
When you use the computer to access e-mail, a network, or the Internet, you potentially expose it to
computer viruses. Computer viruses can disable the operating system, programs, or utilities, or cause them
to function abnormally.
Antivirus software can detect most viruses, destroy them, and, in most cases, repair any damage they have
caused. To provide ongoing protection against newly discovered viruses, antivirus software must be kept up
to date.
Windows Defender is preinstalled on your computer. It is strongly recommended that you continue to use an
antivirus program in order to fully protect your computer.
For more information about computer viruses, access the HP Support Assistant.
Using firewall software
Firewalls are designed to prevent unauthorized access to a system or network. A firewall can be a software
program you install on your computer and/or network, or it can be a solution made up of both hardware and
software.
There are two types of firewalls to consider:
●
Host-based firewalls—Software that protects only the computer it is installed on.
●
Network-based firewalls—Installed between your DSL or cable modem and your home network to
protect all the computers on the network.
52 Chapter 7   Security 
						

							When a firewall is installed on a system, all data sent to and from the system is monitored and compared
with a set of user-defined security criteria. Any data that does not meet those criteria is blocked.
Your computer or networking equipment may already have a firewall installed. If not, firewall software
solutions are available.
NOTE:Under some circumstances a firewall can block access to Internet games, interfere with printer or
file sharing on a network, or block authorized e-mail attachments. To temporarily resolve the problem,
disable the firewall, perform the task that you want to perform, and then reenable the firewall. To
permanently resolve the problem, reconfigure the firewall.
Installing critical security updates
CAUTION:Microsoft® sends out alerts regarding critical updates. To protect the computer from security
breaches and computer viruses, install all critical updates from Microsoft as soon as you receive an alert.
You can choose whether updates are installed automatically. To change the settings, type control panel
in the taskbar search box, and then select Control Panel. Select System and Security, select Windows
Update, select Change settings, and then follow the on-screen instructions.
Using HP Client Security (select products only)
HP Client Security software is preinstalled on your computer. This software can be accessed through the , t
HP Client Security icon at the far right of the taskbar or Windows Control Panel. It provides security features
that help protect against unauthorized access to the computer, networks, and critical data. For more
information, see the HP Client Security software Help.
Using HP Touchpoint Manager (select products only)
HP Touchpoint Manager is a cloud-based IT solution that enables businesses to effectively manage and
secure their company assets. HP Touchpoint Manager helps protect devices against malware and other
attacks, monitors device health, and enables customers to reduce time spent solving end-user device and
