The term “unauthorized access” means invading the privacy of someone’s computer without their consent. Such a situation can arise if you leave your system unattended or use your internet without any firewall to protect against malware and viruses. To protect your data, you can take preventive measures regardless of your operating system.
Today, users know password protection is essential for wireless networks and systems. Irrespective of the fact that cyber rogues can access your private data, there are still a few loopholes that most users aren’t aware of. Therefore, the shortcomings are utilized by cybercriminals to gain access to your system.
This article covers the best tips and techniques to prevent unauthorized computer or network access.
Install all Security Patches
People who use Windows PCs ignore Microsoft updates that ensure the security and protection of your confidential data. These usually pop up during work – thus, users tend to ignore them to avoid interruptions. However, they are unaware that these updates are critical as they include updated security patches that ensure better data protection.
Suppose you are concerned about why these updates are required. In that case, it is because the operating system and browser you use have specific susceptibilities, which may give unauthorized computer access to hackers. In addition, hackers can quickly determine loopholes to invade a computer. It is recommended to set the Microsoft Updates to automatic to save time and valuable data.
Browsing the Internet? Pay Attention to File Sharing
It is critical if you are surfing the internet on a Local Area Network (LAN) with unlimited file-sharing features. To keep your data protected, you should turn off this feature. If you do not want to deactivate it, share files and folders only with users and systems you know. Enrolling it can make your system an easy target for hackers to invade.
Keep the Firewall On
If you understand the concept of a firewall, you should also know its significance. It acts as a protective wall or layer between you and the internet. Before sending, a firewall’s primary responsibility is to track and scrutinize all the data exchanged between the computer and the server. When your firewall thinks there is a threat, a pop-up warning message may notify you. With a firewall turned on, you can quickly stop malware or viruses.
Carefully Read your Email Messages and Know the Senders
Most users need to pay more attention to email security despite knowing it. It is imperative to ignore email messages you receive from unknown sources. Further, do not open any attachments from a source you do not trust. Email attachments are among the oldest methods to send malware and viruses.
Maintain a Proper Backup of your Data Online
One thing that you should avoid doing is surfing the internet for essential data on a computer that is infected. It may further create trouble as hackers can easily invade your computer to get unauthorized access to your valuable data and information. 
Creating and maintaining a backup of all your data online is recommended. There are different platforms available to store your data on the server. Rest assured, such platforms are reliable as they offer limited or unlimited storage space for a specific amount.
Use Strong Passwords
Using a personal password for all your accounts is essential to prevent unauthorized access. Users have to be more careful about this if they use a shared system. Apart from this, make sure to change passwords often.
- Use antivirus software. “Do not avoid security patches.” Download a solid antivirus to prevent viruses, worms, and others. It will prevent your computer from being hacked.
- Keep the software up to date.
- Verify your software security. Do not allow any application to make changes to your computer.
- Back up early and often. Use websites that provide storage and allow you to keep a copy of your information. It will help to keep the data safe.
