Having any computer or device connected to the internet can potentially get the computer or device infected with a virus or malware. A computer virus or malware is any malicious software that runs with or without the user’s knowledge but causes an unwanted effect. Some malicious programs can cause serious damage to the data stored on the computer or device. There are even viruses and malware that record your personal data, such as a credit used to purchase a gift online. With this information, a user’s identity can be stolen or the information used to make purchases without their knowledge or consent. No matter for what purpose you use your computer, whether it is for performing hydrodynamic analysis with an engineering software or simply browsing the internet. Any computer or device connected to the internet requires a level of protection suited for the data stored on the computer. This article explores ways to keep your data and computer safe from malicious software.
Before investing in an entire suite of programs and software to keep your computer and devices safe, you will need to ask yourself how the computer and device is primarily used. If it is only to browse the internet and no sensitive data is stored on the computer or device, then a smaller investment is needed for protecting your data. If sensitive data is stored or used on your computer or device, then it would be better to add the maximum amount of protection. Each layer of security added increases the security of your computer or device in a linear manner. For maximum protection, one would add as many layers that makes financial sense.
The first layer of security that is essential is the network security. Making sure all incoming and outgoing traffic within your own network is encrypted prevents data breaches stemming from network vulnerabilities. Adding another layer for network security would be a firewall. The firewall could be set to only allow trusted ports and connections to pass through your network.
Once your network is secured, you will need to explore more layers when using trusted computers or devices to access the internet. Even though you may have a secure network, your computers or devices accessing the internet could potentially bring in a virus or malware. Many people and companies use a real-time anti-virus and/or anti-malware program. These programs recognize malicious software or website and prevent the user from downloading or visiting the site. Making sure that the anti-virus or anti-malware program is updated daily is also important. Everyday new viruses or malware programs are created and released over the internet, which is why any anti-virus or anti-malware program must have its definitions updated regularly. This allows the program to recognize any potential threats.
Protecting your data from malicious software through many layers of security is a great start. However, no matter how much protection you put in place there still is a possibility of your data being stolen or corrupted. It is just as important to back-up your data and store it in a secure encrypted drive in the case of data corruption. This will allow you to restore your data and continue without losing too much time.
