Introduction - How to Perform Network-Wide Security Event Log Management

Microsoft Windows machines have basic audit facilities but they fall short of fulfilling real-life business needs(i.e., monitoring Windows computers in real-time, periodically analyzing security activity, and maintaining along-term audit trail). Therefore, the need exists for a log-based intrusion detection and analysis tool such asGFI EventsManager.

This paper explains how GFI EventsManager’s innovative architecture can fill the gapsin Windows’ security log functionality – without hurting performance and while remaining cost-effective. Itdiscusses the use of GFI EventsManager to implement best practice and fulfill due diligence requirementsimposed by auditors and regulatory agencies; and provides strategies for making maximum use of GFIEventsManager’s capabilities.

Web Monitoring for Employee Productivity Enhancement

Posted in Security Articles

Introduction

All too often when web monitoring and Internet use restrictions are put into place it hurts company morale and does little to

enhance employee productivity. Not wanting to create friction in the workplace many employers shy away from using what could be a significant employee productivity enhancement tool. Wasting time through Internet activities is simple and it’s a huge hidden cost to business. Just answering a few personal e-mails, checking the sports scores, reading the news headlines and checking to see how your bid is holding up can easily waste an hour of time each day. If the company has an 8 person CAD department and each of them spends an hour day on the above activities, that’s a whole employee wasted!

Employees both want and don’t want to have their Internet use restricted. The key to success in gaining productivity and employee acceptance of the problem is the perception of fairness, clear goals and self enforcement.

Security Threats: A Guide for Small & Medium Businesses

Posted in Security Articles

Introduction - What Does an SMB Need?

A successful business works on the basis of revenue growth and loss prevention. Small and medium-sized businesses are particularly hit hard when either one or both of these business requirements suffer. Data leakage, down-time and reputation loss can easily turn away new and existing customers if such situations are not handled appropriately and quickly. This may, in turn, impact on the company’s bottom line and ultimately profit margins. A computer virus outbreak or a network breach can cost a business thousands of dollars. In some cases, it may even lead to legal liability and lawsuits.

The truth is that many organizations would like to have a secure IT environment but very often this need comes into conflict with other priorities. Firms often find the task of keeping the business functions aligned with the security process highly challenging. When economic circumstances look dire, it is easy to turn security into a checklist item that keeps being pushed back. However the reality is that, in such situations, security should be a primary issue. The likelihood of threats affecting your business will probably increase and the impact can be more detrimental if it tarnishes your reputation.This paper aims to help small and medium-sized businesses focus on threats that are likely to have an impact on, and affect, the organization.

These threats specifically target small and medium-sized business rather than enterprise companies or home users.

Web Security Software Dealing With Malware

Posted in Security Articles

Introduction

It is widely acknowledged that any responsible modern-day organization will strive to protect its network against malware attacks. Each day brings on a spawning of increasingly sophisticated viruses, worms, spyware, Trojans, and all other kinds of malicious software which can ultimately lead to an organization's network being compromised or brought down. Private information can be inadvertently leaked, a company's network can crash; whatever the outcome, poor security strategies could equal disaster. Having a network that is connected to the Internet leaves you vulnerable to attack, but Internet access is an absolute necessity for most organizations, so the wise thing to do would be to have a decent web security package installed on your machines, preferably at the gateway.

There are several antivirus engines on the market and each product has its own heuristics, and subsequently its own particular strengths and weaknesses. It's impossible to claim any one as the best overall at any given time. It can never be predicted which antivirus lab will be the quickest to release an update providing protection against the next virus outbreak; it is often one company on one occasion and another one the next.

Web security can never be one hundred percent guaranteed at all times, but, there are ways to significantly minimize the risks. It is good and usual practice to use an antivirus engine to help protect your network, but it would naturally be much better to use several of them at once. Why is this? If, hypothetically speaking, your organization uses product A, and a new virus breaks out, it might be Lab A or Lab B, or any other antivirus lab, which releases an update the fastest. So the logical conclusion would be that, the more AV engines you make use of, the greater the likelihood of you nipping that attack in the bud.

The Web Security Strategy for Your Organization

Posted in Security Articles

Introduction

In today's business world, internet usage has become a necessity for doing business. Unfortunately, a company's use of the internet comes with considerable risk to its network and business information.

Web security threats include phishing attacks, malware, scareware, rootkits, keyloggers, viruses and spam. While many attacks occur when information is downloaded from a website, others are now possible through drive-by attacks where simply visiting a website can infect a computer. These attacks usually result in data and information leakage, loss in productivity, loss of network bandwidth and, depending on the circumstances, even liability issues for the company. In addition to all this, cleanup from malware and other types of attacks on a company's network are usually costly from both the dollar aspect as well as the time spent recovering from these web security threats.

Fortunately, there are steps a company can take to protect itself from these web security threats. Some are more effective than others, but the following suggestions should help narrow down the choices.
