Website Security
Why need website security?
In this day and age where almost everything is done online on and through the internet. From electronics to clothing and even something as simple as groceries are ordered online. There are so many websites for so many things that security is now the utmost concern for everyone. From the website owner to the website user everyone wants their own platform to be safe and secure. Web security is important to keep the hackers and online thieves from accessing your private data. Without a security system, the users and the website both are open to attacks and spread of viruses.
Your website can be vandalized, your data could be stolen or worse your website could be completely destroyed therefore it is extremely necessary to maintain a website security system to protect yourself from the ones with ill intent.
What exactly is website security?
Website security basically gives you the ability to protect yourself from viruses, malware, and spyware. The most important part is to understand that security threats are real and you will always be vulnerable to threats. So what shall you do to protect yourself in that case? Well, this is where website security comes in.
Website security software is something which protects us from malware and viruses. This software keeps your website, web servers and web applications safe and protects them from attackers. Since website security attackers are becoming more sophisticated the web security also needs to improve hence various number of tools were introduced like scan my server, quterra, detectfy, tinfoil security, and many more. These tools provided security against many kinds of cyber-attacks from simple viruses to dangerous malwares. Know more about protection tools here
What is a computer virus?
A computer virus is a program that reproduces itself by copying itself to another program on your computer. In other words, a virus copies itself in operational applications or documents and spreads itself gradually. The whole reason as to why viruses are created is to disrupt the vulnerable system and steal private data. It is very convenient for the viruses to sneak into computers by evading the security system.
5 signs that you have a computer virus
Did you ever stop and think that your computer or your laptop might be working slowly or even lagging at times.
So here are the signs that will help you:
- 1. Constant pop-up windows
- 2. Reduced performance and processing
- 3. Missing or excess files
- 4. Unwanted programs messages start up
- 5. System crash
Unrelated pop-up ads are a normal indication of a computer virus. sometimes you may see that there is a pop-up ad about an antivirus never click on that ad as it can be another malware or a rogueware hiding behind that message but once you click on it you will allow access for that virus to enter your computer.
If by chance your computer is taking longer than usual to start up or even starting certain programs takes some time check first if it isn't due to the lack of ram or a slower processor if not then it certainly is due to a virus.
Always keep track of the data you keep stored in your computer because viruses tend to delete files from your hard disk or they might even reproduce itself on your computer. If you notice missing or extra files then immediately run an antivirus scan.
Sometimes you notice that some applications start-up even when you don't click on them, then it is sure for a sign that your computer is infected with a virus.
If there is a stop during a program running or your whole system crashes and you see a blue screen in front of you then it's safe to say that your computer isn't working properly now this blue screen or blue screen of death (BSOD) is a Microsoft Windows operating system error screen which is displayed to indicate system conflict.
Important viruses you should know about
Computer virus
A computer virus is a kind of malicious software that when you accidentally open or run it unknowingly starts replicating itself by modifying other computer programs and infecting them with its own code.
Boot sector virus
Boot sector virus is another computer virus that directly infects your storage device's master boot record. Now it is not necessary for the virus to boot the target's computer to infect it. Even start-up of some media which is not bootable can trigger the virus. This virus usually spreads through the means of physical media like a USB drive or a portable hard disk.
Direct action virus
This is the kind of virus what we call a non-resident virus and the way it functions is by selecting multiple files at a time and infects them every time the code is triggered. The virus mainly focuses on replicating itself and spreading the infection whenever it is triggered. Simply put when a program is run then automatically the virus runs too and then it starts replicating itself using other programs as a host.
Resident virus
A resident virus is that kind of a virus which will hide and store itself within the memory banks of the computer. Since it's a resident virus it will load its replication code into the memory so it does not need a trigger mechanism instead the virus becomes active whenever the operating system loads.
Polymorphic virus
As you can understand by the name itself polymorphic virus is something which will constantly replicate or 'morph' when triggered hence making it notorious for antivirus programs to detect. in other words a polymorphic virus, when it starts infecting also duplicates itself and make better and more dangerous copies of itself and changing its appearance every time.
The multipartite virus
A multipartite virus is a type of computer virus that infects files and programs and spreads itself in many other ways. This virus basically follows 2 types of infecting methods i.e. through file infection and boot infection.
File infection - it means that the virus activates and spreads when the infected file is run.
Boot infection - it means that the virus activates and spreads when the computer boots up.
FAT virus
This is another type of virus which was designed to target systems using a Microsoft product. Its purpose is to get into the information database on a computer. The FAT acts like a record book. It stores information about the data, like where it started and what part of the hard drive is unused and then it attacks the file allocation table.
