What is network security?

Network Security includes all the actions that businesses, institutions, and organizations take up on to protect their network, by protecting a network, companies can protect their assets, values, and ongoing operations. A secure network means that a hacker or competitor may not or have difficulties getting critical or sensitive data. A network is well secure when a user has to go through many layers before gaining access to the specified network. So, the more secure layers you have, the more secure the network is.

Why network security is so important?

Network security is a very serious topic. A computer network is probably the most significant system that is running within your home or company. A network is responsible for almost everything that the computer does such as email, web browsing, sharing files, sharing printers, etc. So if your computer network is down by any means, you or an entire company is greatly inconvenienced.

There are numerous amount of security issues that may cause a network to be down. Two of which is, (1) an attack on a personal computer. Example, a computer may be infected with viruses or spyware. (2) real time attack on the servers. Since the servers are responsible for many important functions on the network such as receiving or sending emails, or storing sensitive information about a you or a company, the  penalty would be damaging if the servers have been tampered with.

Network security measures

Since this topic is so serious, we have provided a short list of security measures to think about when you’re installing a Local Area Network (LAN).

Be on the lookout for bugs: A lot of computer viruses are just plain annoying, but do remember that it only takes one malicious virus to crash a network. Buy or download dependable antivirus software, keep them up-to-date and think about other security measures that may help.
Use physical security: This may include keeping your server in a looked room, removing disk drives from workstations that is not in use, and installing alarm systems where necessary. Remember, there is absolutely no security software program out that can protect you from someone breaking in and steal sensitive information.
Stay on top of network security changes: Staying on top of these changes can lower the vulnerability of your LAN. Always try to keep your operating system up-to-date with latest bug fixes and security patches. Frequently use security test to check your network for security holes and possible break-ins. Also for companies, be sure to block access or remove users accounts right after they leave your company.
Use secure passwords: Stay away from passwords that contain dictionary words or personal information. Also avoid giving users the option to change their passwords regularly. A poorly generated password can compromise a whole network.
Use a firewall: A firewall can filter through both incoming and outgoing traffic. There are software firewalls like ZoneAlarm that will protect your network against malicious programs called Trojan horses, which can allow intruders to enter and take control of your computer.

Overall, an effective network security programs involves hardware and software security, as well as programs to educate users. Users should be taught so that they will know what to do. A firewall can only block a few websites, but it is totally up to the user to take precautions when browsing the web.

Passwords are what you use to gain access to your computer or personal information that you’ve saved on it and in your online accounts. If attackers should get a hold of such information, they can use your name to open new credit card accounts, apply for a mortgage, or pretend to be you in online transactions.

Every time you logon to a system, you must be able to show that you are who you say you are. If an attacker or someone else gets a hold of your password, he or she will have full access to any information link to that password. This could involves accessing your files, your email, your student or financial records, payroll and more. Password security is a serious issue. If a password is not properly secure, it can easily wreak havoc in your life if you become a victim of Identity Theft.

Password security is one that not only affects individual users but users on networks on the internet as well. If an attacker has the right tools and education he or she can gain access and control other computers and systems on the same network and take information about local users logging on to those machines.

Finally, it does not take a highly skilled hacker to take control of a computer on which he or she has an account. A majority of these tools used to gain access are downloadable from the internet which require a little or no knowledge of how they work.

Security Camera Systems Commonly Known As CCTV Are More Important Than Ever in Protecting Us

Posted on by

A CCTV System or a Security Camera System are one and the same thing. CCTV means Closed Circuit Television, but since the development of digital Security Camera Systems the phrase CCTV does not reflect what can be achieved now.

A Security Camera System can do all that an alarm system can do but with eyes (cameras). One of the first of many advantages of the security CCTV industry going digital was the ability of a camera to detect motion without a separate PIR. The second benefit was the ability to record digitally to a hard drive, the same as in a computer.

This development meant VHS tape systems would become obsolete. Now, if there has been an incident, and you want to review on your digital Security Camera System, you do not need to run through hours of a VHS tape to find the incident.

A digital system records each incident (motion detected by a camera) as a separate file and logs each file in date and time order. Theoretically if there has been, no incidents, then the system will not have recorded any motion detections. So a quick look at where the files are recorded should show nothing to view.

Unlike a VHS tape which would have recorded for 4 to 8 hours of a cameras view whether there was any detected movement or not. Digital Security Camera Systems (CCTV) were a great advance for the security and monitoring industry as they could reduce the time spent on viewing hours of recordings.

There are basically two types of digital Security Camera Systems available today. PC based surveillance systems and Digital Video Recorders (DVR), which both come as 4, 8, 12, 16 channels (camera inputs). PC based surveillance systems can now have up to 32 channels (camera inputs).

Although these systems are digital, cameras are analogue. It is a bit like the signal we receive for our TV’s, it is analogue but is converted by the TV to digital. Very soon that TV signal will be digital and we must have suitable receivers to handle the new digital signal.

In the same way as TV, Security Camera Systems (CCTV) are now digital but the signal from each camera is analogue. But now that is also changing to a digital signal by way of IP (Internet Protocol) cameras. Although these new IP cameras look similar to analogue cameras the images it sees are processed digitally and transmitted back to the PC based surveillance system or DVR digitally over computer network cable (CAT5/6).

Although CCTV moved into the digital age at the beginning of 2000 it was only the digital video recorders (DVR) that you can call digital. The cameras were and still are mainly analogue. But that is slowly changing with the development of Internet Protocol (IP) cameras. These are truly digital and in some cases are computers in their own right.

Most people’s perception of CCTV is a large retail outlet with a CCTV control room with a security man sitting in front of banks of camera images. Many companies today rely on these CCTV systems to help combat the theft of their stock and protection of their staff. Also most councils and government departments operate CCTV surveillance systems in the fight against crime.

Now the cost of digital Security Camera Systems has come down dramatically due to technological developments and a growing market almost every home owner and business can afford a Security Camera System if they feel they have a need to protect their family, property, business, staff, stock, equipment, etc.

I sold a computer and security business in mid 2008. The main part of the business was the sale and installation of digital security systems commonly known as CCTV. I now help with Internet marketing of a number of family and friends websites along with a number of my own websites. I also provide a consultancy service on security systems through my website http://www.security-camera-system.co.uk.
