Computer Security

Computer security is a very broad term to decipher and its meaning has evolved in recent years. Before data security became one of the biggest issues of concern and widely publicized in the industry, the general idea of computer security was focused on the physical machine.

Computer security means safeguarding any application or data present in your computer. It is a rather broad subject and involves an arsenal of applications and technologies to prevent itself from potential, harmful viruses.


As per the traditions, computer facilities were physically protected for the following three reasons:

- Prevention of theft or any damage to the hardware

- To avoid theft of or damage to the information

- Excluding any disruption of service.

Now since computers are more vulnerable to malware than physical theft, experts have started to realize that they should focus more on the software front.


What is the best security for your home computer?

Every desktop (if running windows) is pre-configured with a robust Windows Defender advanced enough to tackle all risks related to security. The program is quite austere in itself and instantly brings into light the programs that try accessing data they are not deemed to access otherwise.

Though, the defender is equally robust when it comes to safeguarding security, you need certain more advanced security tools – and hardware – to safeguard network.

Below are some of the best security applications you will find in the market. Again, there are other equally powerful applications as well, so we have narrowed our list down to the ones we believe are the best in business –

- Bitdefender

- Kaspersky

- ESET NOD32 Antivirus

Since your computer is at its most vulnerable when connected to the internet, you should prefer internet security over antivirus.


What security do you need to safeguard your computer?

This would be long list. You will need an anti-virus, anti-spyware, firewall and online security. And, to end up saying that your computer is fully safeguarded would be an overstatement. Security tools, however robust, are never sufficient to stop an attack. No matter how carefully and wisely the applications might have been coded, there always lingers risks. The system could be having loopholes that nobody had ever discovered; loopholes that malicious attackers might be waiting to exploit in order to gain unauthorized access to your computer.


Computer security Measures


Earlier, these strict procedures were only and obvious computer security measures to take for an organization. However, advanced virtual machine security measures like remote terminal access, communications, and networking provide meaningful protection for both the information or the service and ensuring that both are perfectly secure.

In the IT industry, the term computer security refers to some simply advanced techniques ensuring that data stored in a computer is not accessible by any unauthorized users or individuals. Most of the computer security measures involve data encryption and passwords.

Do laptops need antivirus?


Yes, all computers, mobile phones, tablets should ideally have an antivirus application installed. Laptops are the same as desktops, though more portable. You would need the same type of security application on your laptop as you would need in a desktop computer. So, yes, laptops need antivirus applications as well.


Is it safe to use laptops or computers without antivirus?

It is not completely safe to use laptops and computers with antivirus, let alone using them without antivirus application. As mentioned earlier, antivirus will only mitigate risk and not eliminate it completely.


Computer security threats

There are several types of computer threats you should be familiar with. Note that we have written “threats” and not “viruses”.


- Trojan horse – a Trojan is not a virus but a program that looks authentic but instead destructs your entire computer. Trojans are not classifies as viruses because they do not replicate.

- Virus – perhaps the only thing that comes to mind when someone talks about computer security threats. One must note than virus is a threat-type. What makes it so lethal is its capacity to attach itself with an exe file, thus leaving behind it, a trail of destruction, infecting files it came contact with. Viruses cannot spread without aid.

- Worm – there is no way no check the spread of worms once your computer is infected by one. Worm is the deadliest of all computer threats, primarily because it can travel between computers without aid. Worms make use of file systems to transfer within the computer.
