Endpoint Protection: New Approaches to Best Practices With such a wide variety of threats to guard against, it's only natural for security administrators to become overwhelmed with preventive maintenance requirements. Ultimately, this leads to gaps in network defense. This article defines the importance of desktop policy enforcement and presents a workable model for all skill ranges of security administrators to utilize for endpoint protection.

One Virus Engine Is Not Enough: The Case for Maximizing Network Protection with Multiple Anti-Virus Scanners All responsible organizations protect their networks from virus attacks by installing an email security product. Yet, how does one choose the right solution out of the wide variety of virus scanning engines available? And is one anti-virus engine enough to protect the internal network from mass-mailing viruses, worms and other email-borne threats?

Norton AntiVirus C.E 7.6 Since the Introduction of Norton Antivirus 7.x, Symantec have managed to created a truly remarkable product with full single point manageability, centralized quarantine, single engine (NavX), remote rollout (Push Based from Console), Web based installer (Pull) , single definition set for all flavors of Nav (Using MicroDefs), customizable Liveupdate technology (Centralized Microdefs) and something new called the Digital immune system ©. Just to mention a few of the new features. In this document I will cover most of the new fetchers of NavCE, I have also included some URL’s at the end of the paper that you can feather research this product.

OpenAV: Developing Open Source AntiVirus Engines This article will take a look at the OpenAntivirus AV engine, assess its progress so far, and offer some suggestions of how the developers can continue to develop it. While some of the commentary in the following sections may be fairly critical, the purpose of this paper is not to flame the OpenAV project or its developers but, on the contrary, to salute their efforts. Hopefully, this article and the comments herein will make a significant contribution to the development of a viable, working open source antivirus product.

Life After AV: If Anti-Virus is Obsolete, What Comes Next? In this article, I will address what I believe will be its replacement - behavioral blocking - including what is currently available, and how behavioral blocking needs to function for it to successfully defeat malicious code.

A Day in the Life of an Anti-Virus Lab The first stage of the process at any lab is to sift out the definitely-innocent non-virus files from the potentially infected ones. Many labs use one or more processes to accomplish this, usually by identifying the known "normal" files by matching them against an ever-growing database of files which have been thoroughly analysed and verified as virus-free. Using checksums and other pattern matching technology, each new file is compared to the known clean files to determine if it should be subject to further investigation or simply culled from the analysis process. If a file matches a known-clean file, it is removed from the process and the customer informed that it is not a virus. On any given day, the ratio of safe to suspect files received in a lab can vary tremendously.

Security Management View of Implementing Enterprise Antivirus Protection This paper provides practical information to consider when planning the deployment, upgrade, design, or engineering of an enterprise antivirus solution. Antivirus solutions usually focus on Microsoft Windows environments, but this paper adds some tangential notes about Macintosh and UNIX variants. Included are descriptions of security management activities that increase the benefit of antivirus product(s) deployment in an enterprise setting, such as describing deployment design within a "layers of defense" paradigm. Other facets of operating, administering, and maintaining antivirus technologies are also described in addition to the identification of some management metrics that quantify the value of antivirus deployment.

Heuristic Techniques in AV Solutions: An Overview Heuristic technologies can be found in nearly all current anti-virus (herein referred to as AV) solutions and also in other security-related areas like intrusion detection systems and attack analysis systems with correlating components. This article will offer a brief overview of generic heuristic approaches within AV solutions with a particular emphasis on heuristics for Visual Basic for Applications-based malware.

Who Goes There: An Introduction to On-Access Virus Scanning, Part One Anti-virus programs protect a computer system from viruses by examining the computer's memory and file system for signs of virus infestation. This examination process is called scanning. Anti-virus programmers use two main scanning strategies - on demand and on access scanning. In on-demand scanning, users voluntarily activate a virus-scanning program each time they want to examine the computer for viruses. In on-access virus scanning, the virus scanner that continually examines the computers memory and file system automatically activates each time one of these resources is accessed by a program.

Malware Myths and Misinformation, Part Two: Attachments, AV Software and Firewalls This article is the second of a three-part series looking at some of the myths and misconceptions that undermine anti-virus protection. In the first part of this series, we considered a class of myths and misconceptions that we summarized as the school of "I'm safe because I don't do Microsoft." In this installment, we will consider a class based on perceived immunity through mail hygiene. It is, perhaps, unfair to regard all of these as myths and misconceptions. They might, however, be regarded as problematic because they tend to lay so much stress on security that they impair an organization's ability to carry out its day-to-day business. The first one, though, is decidedly misleading.
