gfi-languard-how-to-deploy-agent-network-wide-on-servers-workstations-1aGFI LanGuard Agents are designed to be deployed on local(network) or remote servers and workstations. Once installed, the GFI LanGuard Agents can then be configured via LanGuard’s main server console, giving the administrator full control as to when the Agents will scan the host they are installed on, and communicate their status to the GFI LanGuard server.

Those concerned about system resources will be pleased to know that the GFI LanGuard Agent does not consume any CPU cycles or resources while idle. During the time of scanning, once a day for a few minutes, the scan process is kept at a low priority to ensure that it does not interfere or impact the host’s performance.

Cloud-Based Solutions

This section contains useful articles regarding Cloud-based services and how they can help companies save on running costs, administration and investments on new equipment.  We take a look at the top reasons why Small Medium Businesses (SMBs) should consider cloud-based services and what their drawbacks are.

Dealing with User Copyright Infringement (Torrents), Data Loss Prevention (DLP), Unauthorized Remote Control Applications (Teamviewer, RDP) & Ransomware in the Business Environment

GFI WebMonitor - Control user copyright infringement in the Business EnvironmentOne of the largest problems faced by organizations of any size is effectively controlling user internet access(from laptops, mobile devices, workstations etc), minimizing the security threats for the organization (ransomware – data loss prevention), user copyright infringement (torrent downloading/sharing movies, games, music etc) and discover where valuable WAN-Internet bandwidth is being wasted.

Organizations clearly understand that using a Firewall is no longer adequate to control the websites its users are able to access, remote control applications (Teamviewer, Radmin, Ammyy Admin, Remote desktop etc), file sharing applications - Bittorrent clients (uTorrent, BitComet, Deluge, qBittorrent etc), online cloud storage services (Dropbox, OneDrive, Google Drive, Box, Amazon Cloud Drive, Hubic etc) and other services and applications.

The truth is that web monitoring applications such as GFI’s WebMonitor are a lot more than just a web proxy or internet monitoring solution.

Web monitoring applications are essential for any type or size of network as they offer many advantages:

  • They stop users from abusing internet resources
  • They block file-sharing applications and illegal content sharing
  • They stop users using cloud-based file services to upload sensitive documents, for example saving company files to their personal DropBox, Google Drive etc.

The Risk in the Business Environment – Illegal Downloading

GFI WebMonitor The Risk in the Business Environment – Illegal DownloadingMost Businesses are completely unaware of how serious these matters are and the risks they are taking while dealing with other ‘more important’ matters.

Companies such as the Motion Picture Association of America (MPAA) and the Recording Industry Association of America (RIAA) are in a continuous battle suing and fighting with companies, ISPs and even home users for illegally distributing movies and music.

Many users are aware of this and are now turning to their company’s internet resources, which in many cases offer faster and unlimited data transfer, to download their illegal content such as movies, games, music and other material.

An employer or business can be easily held responsible for the actions of its employees when it comes to illegal download activities, especially if no policies or systems are in place.

In the case of an investigation, if the necessary security policies and web monitoring systems are in place with the purpose of preventing copyright infringement and illegal downloading, businesses are less vulnerable to the illegal implications of their users, plus it allows them to track down and find the person responsible.

Minimise Internet Security Threats, Scan & Block Malicious Content, Application Visibility and Internet Usage Reporting for Businesses

gfi-webmonitor-internet-usage-reporting-block-malicious-content-1aFor every business, established or emerging, the Internet is an essential tool which has proved to be indispensable. The usefulness of the internet can be counteracted by abuse of it, by a business’s employees or guests. Activities such as downloading or sharing illegal content, visiting high risk websites and accessing malicious content are serious security risks for any business.

There is a very easy way of monitoring, managing and implementing effective Internet usage. GFI WebMonitor can not only provide the aforementioned, but also provide real – time web usage. This allows for tracking bandwidth utilisation and traffic patterns. All this information can then be presented on an interactive dashboard. It is also an effective management tool, providing a business with the internet usage records of its employees.

Such reports can be highly customised to provide usage information based on the following criteria/categories:

  • Most visited sites
  • Most commonly searched phrases
  • Where most bandwidth is being consumed
  • Web application visibility

Some of the sources for web abuse that can be a time sink for employees are social media and instant messaging (unless the business operates at a level where these things are deemed necessary). Such web sites can be blocked.

GFI WebMonitor can also achieve other protective layers for the business by providing the ability to scan and block malicious content. WebMonitor helps the business keep a close eye on its employees’ internet usage and browsing habits, and provides an additional layer of security.

On its main dashboard, as shown below, the different elements help in managing usage and traffic source and targets:

WebMonitor’s Dashboard provides in-depth internet usage and reporting

Figure 1. WebMonitor’s Dashboard provides in-depth internet usage and reporting

WebMonitor’s main dashboard contains a healthy amount of information allowing administrators and IT managers to obtain important information such as:

  • See how many Malicious Sites were blocked and how many infected files detected.
  • View the Top 5 Users by bandwidth
  • Obtain Bandwidth Trends such as Download/Upload, Throughput and Latency
  • Number of currently active web sessions.
  • Top 5 internet categories of sites visited by the users
  • Top 5 Web Applications used to access the internet

Knowing which applications are used to access the internet is very important to any business. Web applications like YouTube, Bittorrent, etc. can be clearly identified and blocked, providing IT managers and administrators a ringside view of web utilisation.

The Most Dangerous Websites On The Internet & How To Effectively Protect Your Enterprise From Them

whitepaper-malicious-website-contentCompanies and users around the world are struggling to keep their network environments safe from malicious attacks and hijacking attempts by leveraging services provided by high-end firewalls, Intrusion Detection Systems (IDS), antivirus software and other means.   While these appliances can mitigate attacks and hacking attempts, we often see the whole security infrastructure failing because of attacks initiated from the inside, effectively by-passing all protection offered by these systems.

I’m sure most readers will agree when I say that end-users are usually responsible for attacks that originate from the internal network infrastructure. A frequent example is when users find a link while browsing the Internet they tend to click on it to see where it goes even if the context suggests that the link may be malicious. Users are unaware of the hidden dangers and the potential damage that can be caused by clicking on such links.

The implications of following links with malicious content can vary for each company, however, we outline a few common cases often seen or read about:

  • Hijacking of the company’s VoIP system, generating huge bills from calls made to overseas destination numbers (toll fraud)
  • The company’s servers are overloaded by thousands of requests made from the infected workstation(s)
  • Sensitive information is pulled from the workstations and sent to the hackers
  • Company Email servers are used to generate and send millions of spam emails, eventually placing them on a blacklist and causing massive communication disruptions
  • Remote control software is installed on the workstations, allowing hackers to see everything the user is doing on their desktop
  • Torrents are downloaded and seeded directly from the company’s Internet lines, causing major WAN disruptions and delays

As you can see there are countless examples we can analyze to help us understand how serious the problem can become.
