CHAPTER 1. KASPERSKY ANTI-
HACKER
1.1. Introduction
What is Kaspersky Anti-Hacker?
Kaspersky Anti-Hacker is a personal firewall that is designed to safeguard a
computer running a Windows operating system. It protects the computer against
unauthorized access to its data and external hacker attacks from the Internet or
an adjacent local network.
Kaspersky Anti-Hacker:
• Monitors the TCP/IP network activity of all applications running on your
machine. If it detects any suspicious actions, the program notifies you and
if required, blocks the suspect application from accessing the network.
This allows you to preserve confidential data on your machine. For example, if a Trojan tries to transmit any data from your computer, Kaspersky
Anti-Hacker will block this malware from accessing the Internet.
• The SmartStealth™ technique makes it difficult to detect your computer
from outside. As a result, hackers will lose the target and all their attempts
to access your computer will be doomed to fail. Besides, this allows for
prevention of the DoS (Denial of Service) attack of all types. At the same
time you will not feel any negative influence of this mode while working on
the Web: the program provides conventional transparency and accessibility of the data.
• Blocks the most common hacker network attacks by permanently filtering
the incoming and outgoing traffic, and also notifies the user about any
such attacks.
• Monitors for attempts to scan your ports (these attempts are usually followed by attacks), and prohibits any further communication with the attacking machine.
• Allows you to review the list of all established connections, open ports,
and active network applications, and if required, lets you terminate unwanted connections.
Kaspersky Anti-Hacker 7
• Allows you to secure your machine from hacker attacks without special
configuration of program settings. The program allows simplified management by choosing one of five security levels: Block all, High, Medium,
Low, Allow all. By default the program starts with the Medium level, which
is a training mode that will automatically configure your security system
depending on your responses to various events.
• Allows flexibility of security system configuration. In particular, you can set
the program to filter network operations into wanted and unwanted, and
you can configure the Intrusion Detection System.
• Allows you to log certain security-related network events to various special-purpose logs. If required, you can define the detail level of the log entries.
The program may be used as a separate software product or as an integral
component of various Kaspersky Labs solutions.
Attention!!! Kaspersky Anti-Hacker does not protect your computer from
viruses and malicious programs that can destroy and/or corrupt your
data. It is advised that you use Kaspersky Anti-Virus Personal for this
purpose.
1.2. What’s new in v. 1.5
New features of version 1.5
The new version of this program:

CHAPTER 3. STARTING WORK
How to start working with the
software product. Example of
security system configuration
As soon as you install the program and restart your computer the security system
is activated. In fact, from this very moment, Kaspersky Anti-Hacker is monitoring
for attacks against your machine and attempts by your applications to interact via
a local network or the Internet.
After you enter the system you begin to work as usual. When no network
connection is established, the security system on your machine is indicated only
by the

current security level and change this level if required (for details of the program
main window refer to subchapter 5.3 on page 29). By default the Medium level is
enabled. This level allows you to configure your security system conversationally.
In most cases you will not have to configure the system yourself: the most
frequently used applications are allowed by default to establish network
connections strictly according to their type. However sometimes you will have to
configure your security system manually. Let’s review the corresponding
example:

Follow these steps:
1. Select the Allow activity of this application according to its
type option button and Web browser (IE, Netscape...) from the
drop-down list.
2. Press ОК.
After this, Kaspersky Anti-Hacker will allow Microsoft Internet Explorer
to establish the connection. In addition, the application will be allowed to
establish other connections in accordance with its type.
As you have probably noticed, there are three options in the Create a rule for
IEXPLORER.EXE dialog box:
• Allow activity of this application according to its type (the option you
selected in the example above) – allows only network communication that
is compliant with the specified application category. Select the required
category from the drop-down list below the option button. You can allow
any activity of this application by selecting Allow all from the drop-down
list.
Starting Work 21
• Block any network activity of this application – blocks the specified
application from any kind of network activity including the described operation.
• Customize the rule – allows you to specify the operations that will be al-
lowed for this application. If you select this option button and click ОК, the
rule wizard window will appear on your screen. Use the rule wizard to define requirements for the operations to be allowed for this application (for
details of the rule wizard see subchapter 6.3.2 on page 49).
If you are not sure which option to select, use the Allow once or the Block once
buttons at the bottom of the dialog box. Later on you will be able to monitor the
application behavior and decide which option to select.
If you close the training window by pressing the
right corner, the operation at issue will be blocked this time.

In this way you can conversationally configure your computer security system in
an appropriate way.
To review the list of defined rules, select Application rules from the
Service menu or press the
button in the main window toolbar.
We recommend that you use the Medium level for the first few weeks after
program installation. This will allow the program to automatically configure your
security system depending on your responses to various network events. Create
the rules allowing standard network operations.
When the training period is over, you can switch the program to the High level,
and secure your computer against any unauthorized network events and hacker
attacks. However, remember the newly installed applications will by default be
disabled from accessing the local network and/or the Internet. To teach your
Kaspersky Anti-Hacker to handle these new applications you will have to switch it
back to Medium or manually define the appropriate rule for these applications.
CHAPTER 4. KASPERSKY ANTI-
HACKER – PREVENTING
HACKER ATTACKS
4.1. Kaspersky Anti-Hacker
Operating Principles
How does Kaspersky Anti-Hacker
operate? Application rules. Packet
filtering rules. Intrusion Detection
System.
Kaspersky Anti-Hacker protects your computer from network attacks and
preserves your confidential data. To do this, Kaspersky Anti-Hacker monitors all
network operations on your computer. There are two types of network operation:
• Operations on the application level (high-level). At this level, Kaspersky
Anti-Hacker analyses activity of network applications, including web
browsers, mail programs, file transferring programs and others.
• Operations on the packet level (low-level). At this level, Kaspersky AntiHacker analyses data packet sent/received by your netcard or modem.
You work with Kaspersky Anti-Hacker by creating special filtering rules for
network operations. Some filtering is performed automatically by the Intrusion
Detection System, which can detect port scanning, DOS attacks, etc., and can
then block the assaulter. In addition, you can define your own filtering rules to
reinforce protection of your machine.
For every type of network operation there are separate lists of Kaspersky AntiHacker rules.
• Application rules. Here you can select the required application and allow
an activity that is compliant with the application type. You can define any
number of rules for every application, as required. If any network activity
not meeting conditions of the rule is detected on your machine, the program will notify you and allow you to block the unwanted action (if Me-
Kaspersky Anti-Hacker – Preventing Hacker Attacks 23
dium level is enabled). In order to define the simplest rule for an application, you can simply select its type from the drop-down list (for details see
subchapter 6.3.2.1 on page 49). To define a more complicated rule, you
can specify the remote services and addresses allowed for this application.
• Packet filtering rules allow or block network packets sent or received by
your machine. These rules review the packet header (the protocol used,
the port numbers, the IP addresses etc.), and take decisions on the basis
of this data. These rules are applied to all network applications running on
your machine. For example, if you create a rule to block a certain IP address, all network communications to this address will be prohibited.
Packet filtering rules have a higher priority than application rules, i.e.
these rules are instigated first. For example, if you create a rule to block
all incoming and outgoing data packets, then the program will apply no
application rules while filtering data packets.
4.2. Security Levels
What security levels are supported
by Kaspersky Anti-Hacker?
The program allows you to select one of the following security levels:
• Allow all – disables the security system on your machine. When this level
of security is selected, any network activity is allowed on your machine.
• Low – allows network activity of all applications except those explicitly
prohibited by user defined application rules.
• Medium – notifies you about network events related to your applications
and allows you to configure your security system for optimal performance.
If a network application on your computer tries to connect to the local
network or the Internet, the training mode will be activated. The application and the network operation details will be displayed on your screen.
On the basis of this data the program will prompt you to select one of the
following courses of action: to allow or to block this event once, to completely block activity of this application, to allow the application activity according to its type, or to define additional network communication settings.
Depending on your answer, the program will create a rule for this application that will subsequently be applied by the program automatically.
• High – prohibits network activity for all applications except for those ex-
plicitly allowed by user defined application rules. When this security level
24 Kaspersky Anti-Hacker
is enabled, the program training dialog box does not appear on your
screen, and all attempts to establish connections not defined in the user
rules are blocked.
Remember that all applications installed after you switch to this
security level are by default disabled from accessing the Internet
or the local network.
• Block all – disables your computer from accessing the Internet or the lo-
cal network. This level creates a situation in which all attempts to establish connection via the Internet or the local network are blocked as if your
computer is physically disconnected.
With the High, Medium or Low level enabled you can set the
supplementary security tool – Stealth mode (see subchapter 5.6 on
page 33). This mode allows only the network activity initiated by you, all
other types of activity (remote access to your machine, checking of your
machine using the ping utility and so on) are prohibited, if not explicitly
allowed by the user rules.
Actually it means that you computer becomes "invisible" from the
external environment. Hackers lose the target and all their attempts to
access your computer are doomed to fail. Besides, this allows for
prevention of the DoS (Denial of Service) attack of all types.
At the same time you will not feel any negative influence of this mode
while working on the Web: Kaspersky Anti-Hacker allows the network
activity initiated from your machine.
Attention! The intrusion detection system is enabled for all security
levels except for Allow all. However, if required, you can manually
disable it (see subchapter 6.5.1 on page 69).
4.3. Recommended Settings
How to select proper security levels,
and define rules for various
situations?
What components of Kaspersky Anti-Hacker should be used and what security
level should be selected? The answer depends on the task you want to
accomplish.
Task 1. How to protect your data from external attacks via the
Internet?
Kaspersky Anti-Hacker – Preventing Hacker Attacks 25
The following are two of the main methods used by hackers to steal
or corrupt user data via the Internet: penetration into a target computer system using computer software errors, and infection of a target
computer by Trojans.
If you learn about an error in one of the programs installed on your
machine, be sure to create a blocking rule for this application. It is
advised that you create a complex blocking rule (see
subchapter 6.3.2.1 on page 49) that will take into account features of
this error.
Suppose your computer is infected by a Trojan via a diskette or by
email, and the malicious program attempts to send some data via the
Internet. Kaspersky Anti-Hacker will easily preserve your data by
blocking this operation (at the High level), or by issuing an
appropriate notification (at the Medium level).
Attention!!! Kaspersky Anti-Hacker does not protect your computer
from viruses and malicious programs.
For example, a Trojan may use a standard mail program on your
computer to send out your confidential data. In this case Kaspersky
Anti-Hacker will not be able to prevent the action. Moreover, if your
computer is infected by a virus or a malicious program, your data may
simply be destroyed and the computer may become a virus source. In
this case Kaspersky Anti-Hacker may only partially eliminate consequences of the infection. To effectively protect your system from viruses and malicious programs it is advisable that you use the
Kaspersky Anti-Virus Personal/Personal anti-virus program in combination with Kaspersky Anti-Hacker. Also, we recommend that you
create application rules allowing your computer applications to engage in activity strictly according to their type. It is also advisable that
you use the list of application rules to assign those types of activities
to the applications that strictly correspond to operations allowed for
these applications. This way, the risk of unauthorized network operations performed on your machine will be minimized.
Suppose, you learn that your computer is constantly attacked by a
remote machine.
Task 2. How to block attacks from certain Internet addresses?
You may prohibit your computer from communication with certain
remote addresses by configuring appropriate packet filtering rules.
For example, in figure 12 you can see a rule blocking communication
with the 111.111.111.111 address.
To prevent from such situations, it is advisable that you keep your
Intrusion Detection System enabled.

For example, you may use Kaspersky Anti-Hacker to block banner
display on web pages. To do this, create a packet filtering rule to block
communication with web sites from where the banners are usually
downloaded (for example, linkexchange.ru).
Suppose you are afraid of attacks from the local network or want to
protect your personal data from thieves.
Task 3. You must monitor operations on the local network
The computer communicates with a local network at the operating system level, therefore it is not always possible to identify the application
involved. In this case you must create an appropriate packet filtering
rule to secure your data.
In order to simplify configuration of the security system, Kaspersky AntiHacker preinstalls some packet filtering rules allowing communication
via the local network. By default the local network is allowed. However,
you can redefine the default packet filtering rules to completely block
access to the local network, or allow it only for certain computers.
