What is Firewall?

A firewall is a device or set of devices configured to permit, deny, encrypt, or proxy all computer traffic between different security domains based upon a set of rules and other criteria. In another words, a firewall is a dedicated appliance, or software running on another computer, which inspects network traffic passing through it, and denies or permits passage based on a set of rules.

 

Security Threats

Security is the soft white underbelly of broadband Internet service and the threats are real. How pervasive are security threats on the Internet?

The 2000 Computer Crime and Security Survey published by the FBI and Computer Security Institute found that 71% of all companies reported being attacked by independent external hackers in the last 12 months.

A Gartner Group survey shows more than over 50% of small and midsize enterprises (SMEs) using the Internet will be hit by hackers.

According to IDC, the average new DSL connection experiences three attempted “hacks” in the first 48 hours.

Security threats come in a variety of forms, but the end result is the same: a serious disruption to your business. Compounding the security weaknesses of the Internet is the widespread availability of “hacker-helper” programs on the Internet. Today, talented hackers are writing extremely powerful hacking tools and making them available for download on the Internet. No longer must the attacker be an expert or understand the nuances of the target’s vulnerabilities, all they need to do is point the tool at the target and hit the “Attack” button. A complete security solution protects your business from unauthorized access to network, Denial of Service (DoS) attacks, viruses, inappropriate content, as well as private data communications over the Internet via a VPN. Therefore, Timeer Networking Services offers the total protection for your company with the Firewall Protection.

Common Types of Internet Security Threats Your Business Faces

  • Unauthorized Access to Your Network. Hackers breaking into your network can view alter, or destroy private files. A hacker can, for example, modify accounting, medical, or academic records, and then leave, with the break-in and changes going undetected until it is too late. Hackers may use a variety of readily available "hacker's helper" tools to break into the network Once in, the hacker has control of your computer and access to your confidential data.

  • Denial of Service (DoS) Attacks. Increasingly prevalent Denial of Service (DoS) attacks, such as Ping of Death, SYN Flood and LAND Attack, aim not to steal information, but to disable a device or network so users no longer have access to network resources. Even if your network is not being attacked, it can be used as an unwitting ally in Denial of Service attacks on other networks. Using Trojan Horses or other malicious attachments, hackers plant tools on hundreds and sometimes thousands of computers to be used in future attacks. So, in addition to protecting your own LAN from attacks, you need to prevent your LAN computers from being compromised and used in attacks on others.

  • Capture of Private Data Going Over the Internet. As your private data moves over the Internet, hackers using programs called packet sniffers can capture your data as it passes from your network over the Internet and convert it into a readable format. The source and destination users of this information never even know that their confidential information has been tapped.

  • Offensive Content. Inappropriate Internet content can create an uncomfortable work environment and cause potential legal problems for your business. Network users risk viewing inappropriate content, decreasing productivity, and inviting lawsuits by abusing company resources with unregulated Web browsing.

The common internet security threats above can be avoided if you have a properly configured and up to date firewall. Please contact our Houston office, or use the Contact Us form to start protecting your data from the Internet World.
