F-Secure Client Security Components and Features................. 18

Introduction to F-Secure Policy Manager ................................... 23

Basic Terminology ...................................................................... 26

1.1 Overview

This section describes the main components of F-Secure Client Security

and F-Secure Policy Manager and provides an introduction to policy

based management.

1.2 F-Secure Client Security Components and

Features

F-Secure Client Security is used for protecting the computer against

viruses, worms, spyware, rootkits and other malware, and against

unauthorized access from the network. F-Secure Client Security consists

of Virus Protection, Internet Shield, and Application Management. When

installing F-Secure Client Security, you can select which of these

components are installed.

1.2.1 Virus and Spy Protection

Virus and Spy Protection includes several scanning methods: Real-Time

Scanning, E-mail Scanning, Web Traffic Scanning, Rootkit Scanning, and

Manual Scanning. It also includes System Control, Automatic Updates,

the F-Secure Automatic Update Agent and the Virus News service.

Real-Time Scanning

The Real-Time Scanning feature gives you continuous protection against

viruses and spyware as files are opened, copied, moved, renamed and

downloaded from the Web.

Real-Time Scanning functions transparently in the background, looking

for viruses whenever you access files on the hard disk, diskettes, or

network drives. If you try to access an infected file, Real-Time Scanning

will automatically stop the virus from executing. It will then either remove it

from the file or display a warning, as specified in the security policy. For

more information, see “Configuring Real-Time Scanning”, 164.

CHAPTER 1 19

E-mail Scanning

E-mail Scanning can be used for scanning both incoming and outgoing

e-mail messages and attachments. It prevents viruses from getting inside

the company network and it also prevents you from accidentally sending

infected attachments outside. E-mail Scanning can be configured to drop

infected attachments from incoming e-mails. When it has found an

infection in an outgoing e-mail, it can block the outgoing e-mail traffic until

the problem has been solved. For more information, see “Configuring

E-mail Scanning”, 172.

Web Traffic (HTTP) Scanning

Web Traffic Scanning protects computers against viruses in HTTP traffic.

It scans HTML files, image files, downloaded applications and executable

files, and removes viruses automatically. For more information, see

“Configuring Web Traffic (HTTP) Scanning”, 176.

Rootkit Scanning

If you want to ensure there are no suspicious hidden files, hidden

processes, hidden applications or hidden drives in your computer, you

can scan the system manually for rootkits. For more information, see

“Configuring Rootkit Scanning (Blacklight)”, 170.

Manual Scanning

You can use Manual Scanning, for example, after you have installed

F-Secure Client Security, if you suspect that there might be a virus or

spyware on the computer, or if a virus has been found in the local area

network. You can select whether all files or only a certain types of files are

scanned. You can also decide what action to take with an infected file, the

Disinfection Wizard will guide you through the process. You can also use

the Scheduled Scanning feature to scan your computer automatically

and regularly, for example weekly or 1-2 times a month.

20

System Control

System Control is a new, host-based intrusion prevention system that

analyzes the behavior of files and programs. It provides an extra-layer of

protection by blocking undiscovered viruses, worms, and other malicious

code that try to perform harmful actions on your computer. For more

information, see “Configuring System Control”, 169.

Automatic Updates

The Automatic Updates feature keeps the virus and spyware definitions

always up-to-date. The virus definitions updates are signed by F-Secure

Anti-Virus Research Team. The signature is based on strong encryption

and the packet cannot be altered in transit.

In case of complex viruses the virus definitions updates include removal

tools that are executable binaries. The integrity of the delivered

executable code is very important, and F-Secure scanning engines check

that all update code is signed by F-Secure Anti-Virus Research. If the

integrity is compromised, the code will not be executed. For more

information, see “Configuring Automatic Updates”, 159.

F-Secure Automatic Update Agent

With F-Secure Automatic Update Agent, you are able to receive virus

definition updates and informational content without interrupting your

work to wait for files to download from the Web. F-Secure Automatic

Update Agent downloads files automatically in the background using

bandwidth not being used by other Internet applications, so you can

always be sure they will have the latest updates without having to search

the Web.

If the F-Secure Automatic Update Agent is always connected to the

Internet, it will automatically receive new virus definition updates after

they have been published by F-Secure.

When the F-Secure Automatic Update Agent service is started, it

connects to F-Secure’s Automatic Update Server. The agent will keep

polling the server regularly to see whether there is new content available.

The agent downloads only the parts of virus definitions that have changed
