Remote Administrator Overview

ESET NOD32 Antivirus Overview

ESET NOD32 Antivirus is an award-winning, multi-platform, unified anti-threat system

with a powerful graphical user interface. NOD32 stops more than just traditional viruses

-- it also detects, removes, and prevents these threats:

Adware

RATs (remote access tools)

Spyware

Trojan horses

Worms

Rootkits

Keyloggers

Potentially dangerous applications

These threats could affect the privacy, security, and confidentiality of the information on

a computer. Collectively, they are referred to as malicious software, or malware.

ESET NOD32 uses award-winning technology to detect tomorrow’s threats, in real-time,

by analyzing code execution for malicious intent – keeping you ahead of the malware

writers.

Core ESET NOD32 Antivirus Technology

ESET NOD32 Antivirus employs a unique technology called ThreatSense®, an optimized

scanning engine that looks for threats in four different ways in parallel:

Traditional signatures

Generic signatures

Passive heuristics

Active heuristics

First, let’s take a look at these methods as general concepts...

Remote Administrator Overview

Traditional Signatures

A specific threat has a specific set of bytes that uniquely identifies it.

Searching for that exact pattern of

bytes, an anti-threat tool can find and

identify that specific threat.

Though well suited to exploit

detection, signature scanning is

reactive and based on the

identification of a single object.

Because of this, it has limitations

against today’s advanced threats.

Limitations for Signature-based Threat Scanning

New threats are not detected until signatures are generated. PCs may be vulnerable

for hours, days, or weeks.

Malware writers use achiving and packing techniques to circumvent signature-

based detection. Compressing files hides the malware from signature-based tools.

Only some parts or forms of a complex virus may be detected initially. With a

polymorphic (dynamically changing) virus, some infected files might remain

undetected.

Pattern recognition techniques like signatures work effectively and efficiently for known

threats, but are ineffective for protecting against new threats. Heuristic scanning is the

solution to this problem...

Heuristics Explained

Heuristics is a method that uses rules to solve problems. For anti-threat software,

heuristics are a set of rules used to detect malicious behavior without needing to

uniquely identify the specific threat, as a classic signature-based “virus scanner” does.

Heuristics used by an anti-threat program might have rules to look for things like this:

Something that tries to copy itself into other programs

A program that decrypts itself when run

Code that binds to a TCP/IP port and listens for instructions over a network

connection

A process attempting to manipulate (copy, delete, modify, rename, etc.) files

required by the operating system or applications

Remote Administrator Overview

The advantage of heuristics is it can detect not just variants, or modified forms, of

existing malicious programs, but also new, previously unknown malicious programs.

Generic Signatures

One way to use heuristics to improve signature-based detection is to use generic

signatures. A generic signature is a scan pattern that matches more than one specific

piece of malware, possibly an entire family or set of variants.

Generic signatures help an anti-threat

system measure how similar something

is to known malware. Does it look like

anything we already know?

By looking for similarities, the anti-

threat tool can spot malware it hasn’t

seen before, without requiring a

definitive signature for that specific

threat.

However, Generic signatures may be

too restrictive, only finding threats that

have only minor differences.

Passive Heuristics

Passive Heuristics analyze a program as it is scanned, tracing through the instructions in

a program before passing the code to the processor for execution.

The idea is to analyze the suspicious

code to see what it appears to be

designed to do.

Passive heuristics rules look for

patterns, routines, or program calls that

indicate malicious behavior. This

approach is sometimes called

“code analysis.”

Passive heuristics, though a useful tool,

is very difficult to do well. There is no

single action that a malicious program

can perform that is not also allowed in

a “good” program.

Remote Administrator Overview

Active Heuristics

With active heuristics, the anti-threat system can execute the code to see what it actually

does. Execution occurs in a controlled, protected environment to avoid real damage.

The engine lets the code run in a

virtual environment and examines the

behavior performed in and changes

made to that virtual environment.

Active heuristics are useful in defeating

encryption, compression, and

polymorphic threats. It causes the

malware to “show” what it is designed

to do. This provides immediate

protection, not relying on signatures of

known threats for identification.

Since the code actually runs, it can’t

hide its malicious content.

ThreatSense® - Leveraging all detection

The best anti-threat solution is one that makes intelligent use of all viable detection

methods. That’s the idea behind NOD32’s ThreatSense® technology.

Viruses, worms, and spyware are constantly evolving as malware writers try to

circumvent security software. ThreatSense keeps NOD32 a few steps ahead.

The ThreatSense engine is a sophisticated, well-balanced system of advanced heuristics

and malware signatures, providing the best detection without compromising speed or

detection.

For most existing threats, ThreatSense includes a traditional form of malware signatures.

It also uses next-generation generic signatures to quickly detect known malware families

and their future variants.

Remote Administrator Overview

In addition to traditional and generic signatures, ThreatSense’s advanced heuristics

proactively decode and analyze executable code in a protected environment to identify

increasingly sophisticated malicious behavior, characteristic of today’s evolving threats.

What makes ThreatSense technology so accurate is its ability to perform all these types

of detections in parallel, not only improving its detection but also the speed with which

it operates. ThreatSense’s blended approach to detection leverages the benefits of each

technology and makes NOD32 the fastest, most accurate, and lowest impact solution in

the industry.

The Value of NOD32

If you’re managing thousands of workstations and servers across remote locations, you

need a robust, comprehensive solution you can rely on. NOD32 provides all-in-one

protection, small footprint, and fast performance, regardless of the size of the

organization. ESET NOD32 Antivirus products are advanced and easy on system

resources.

NOD32’s Remote Administrator makes it easy to deploy, monitor, and manage 10,000

machines from a single console. This powerful centralized management console installs

in minutes. An entire network of 500 machines can be installed in just a few hours.

technology is at the core of each product ensuring the most-advanced protection

regardless of platform or network configuration.

Let’s begin by looking at the advanced protection available for individual workstations...

NOD32 for Windows Workstations

Desktop and mobile PC users can get the anti-threat protection they need with NOD32

without having to sacrifice detection or speed. And NOD32 is one of a very few products

that currently supports Windows® 64-bit systems

NOD32 was designed to perform anti-threat detection and prevention in two different

areas:

On-Access scanning – scanning files and data as they are accessed, safeguarding the

system at the most likely point of vulnerability. On-Access scanning also targets

operations with a specific type of data access (email, HTTP, etc.)

On-Demand scanning – scanning systems (storage, memory, boot sectors, etc.) as a

definitive task, either as desired or as a regularly scheduled operation.

What does ESET NOD32 Antivirus do?

ESET NOD32 Antivirus searches for threats within PCmemory, the system areas of disks,

files stored on those disks, and on HTTP and POP3 communication streams. A number of

different objects can hold viruses or other malware, such as files, archives, self-extracting

archives, run-time packers, and e-mail. NOD32 can open and inspect a variety of archive

file formats, including self-extracting files and files compressed with runtime packers.

NOD32 uses a variety of techniques to detect threats, which allow NOD32 to detect new,

unknown threats that may not have a name yet.
