In the field of Computer Networking support, the specializer area of network security consists of the plannings and policies adopted by the Computer network administrator and network support specialist to prevent and monitor without official authorization access, misuse, modification, or denial of the computer network and network-accessible resources.
Computer networking support and security is the process of preventing and detecting unauthorized use of your computer. Prevention measures help you to stop unauthorized users (also known as “intruders”) from accessing any part of your computer system. Detection helps you to determine whether or not someone attempted to break into your system, if they were successful, and what they may have done.
The term network security refers to steps taken with the intention of protecting your computer and data network of threats from Trojan horses, worms, viruses, ad ware, hacker attacks, spyware, denial of service attacks, identity theft and theft by data interception.
In short, small business network security measures are implemented to protect the computers in your office by ensuring their integrity, reliability, usability and safety of your computer network and data. Effective network security targets a variety of threats and stops them from entering or spreading on your network.
Implementation of Network Security
To better understand its implementation, let us consider a hypothetical example. Let us assume a new Fort Knox was being setup and you were in charge of its security. How would you go about ensuring the security of the vault and the bank in general?
You would probably want to start at the vault itself by building one of solid steel or titanium having three feet thickness or so. The thickness would make it impervious to drilling or even powerful blasts. Then you would probably install movement detectors, heat detectors and tremor sensors. For the vault door itself you would probably want to use the world’s best locking system controlled by two or more authorized personnel. Moving one layer ahead, you might consider it a good idea to have a posse of security guards to prevent all but only authorized personnel from approaching the vault and so on. In other words, you would rely on several measures implemented like layers of an onion. And that is also exactly how computer network and data security measures are implemented – there is no one particular software or hardware rather, it is several measures implemented at several levels.
All these measures need to be reviewed no less than once a year because hackers and malicious software creators quickly learn how to bypass your security measures by hard work, sheer ingenuity and lots of skill. Computer network even includes your peripheral and communication devices. Hackers are known to routinely hack into the telephone network, pretend to be an authorized employee and phone up the system administrator to request that the password to a certain computer or wifi router be reset. A few seconds is all it takes for the hacker to get into your computer system.
Network security solution and measures include but are not limited to installation of up-to-date anti-virus and anti-spyware, anti-adware, properly configured state-of-the-art firewalls, intrusion prevention systems and virtual private networks (VPN’s), to ensure secure remote access.
Major Benefits of Network Security
A good network security ensures that your company meets the mandatory regulatory compliance because network security helps protect sensitive data and reduces the risk of legal action from affected parties due to data theft. Network Security also saves your company a lot of embarrassment by not getting bad media attention that follows any security breach, it also protects from unwanted (and usually expensive) disruptions. Ultimately, network security ensures the protection of your most important asset – your business reputation.
