Since Windows 10 contains free antivirus, is it unnecessary to take security measures? Consider whether it is necessary to install premium antivirus, and use it for the security of your own PC.
Does Windows 10 Need Antivirus Software?
Microsoft has installed antivirus software called "Windows Defender" on Windows 10. The software that comes standard is free to use. If I have antivirus software that I can use for free, do I have to install antivirus software? We will explain the basic contents of the standard antivirus software.
Windows Defender Reliability
The role of antivirus software is to prevent cyber attacks. In that respect, it's not bad at all. However, the disadvantage is that there are many differences in the attacks that can be prevented depending on how the user sets them. If you make a mistake in the settings, you may be attacked by attacks that you should be able to prevent. As a result, the performance is inferior to other antivirus software. Another drawback is that there are many false positives. It has also been reported that other antivirus software detected malware that was not determined to be malware.
Is Windows Defender the Minimum?
Antivirus has traditionally been left to the individual consciousness. As a result, the number of PCs infected with malware is increasing, and there are increasing cases of damage to the surroundings. Windows Defender was adopted as a measure to prevent the damage from becoming large. Therefore, it can be said that the minimum necessary security measures are required. In fact, security measures are limited to antivirus and firewalls. It meets the requirements in terms of the minimum required security, but it may not be sufficient in dealing with new threats that are emerging one after another.
Key Features of Windows Defender
What are the specific functions of the standard antivirus software that can take basic security measures? I will explain each function.
Real-time Protection
"Real-time protection" is a function that checks the downloaded file for malicious code or data. When the browser downloads the file, if it finds malicious code or data, it will notify the user. This function prevents malware infection by downloading files.
Content Scan
"Content scan" checks the file for fraud. All that is done automatically is a "quick scan" that looks at the core and commonly used locations of the system. All other scans are manual. There is a "Full scan" to check the whole and "Custom scan" to check the specified location. There is also a feature called "Windows Defender Offline Scan". Windows Defender Offline Scan is a useful feature when you are infected with a virus. After rebooting and running the Defender, you can scan your entire PC even if you are not connected to the internet.
Firewall
"Firewall" detects and blocks unauthorized communication in the rules for network communication such as TCP, UDP, and IP. Since it is a function that mainly works to prevent intrusion, if the company's PC is infected with a virus with the same settings, the damage may spread. To prevent the spread of infection from communication from your company's PC, change the settings and block communication when infected with a virus.
SmartScreen
This is a function that alerts the user, "Are you sure you want to access?" When trying to display a site that distributes malicious software or is phishing. I have a list of dangerous sites and I will display a message accordingly. Unlike security, which operates by detecting the behavior of malware, it operates when a list or certain conditions are met.
Companies Need to Take Measures Outside the Cover
These basic functions are just a part of security measures. There are many attacks that require other countermeasures. Therefore, companies need to take measures outside the cover introduced below.
Spam and Ad Blocking Premium
Malware infections often result from spam emails. Therefore, being able to block spam reduces the risk of virus infection. Adblocking is also an effective security measure. There is also a way to pretend to be an advertising banner and lead to a malicious site, so it is a good idea to block it.
Behavior Detection
New viruses are being born one after another. Therefore, security measures are not sufficient with conventional systems that detect known information. That is where "behavior detection" comes in handy. Since it is a mechanism that judges by the movement of the virus, not the information in the pattern file, there is a high possibility that it can handle a completely new virus.
Conclusion
The number of PCs infected with the virus has increased, and the damage has begun to spread around it. To deal with this situation, Windows Defender was created so that anyone can take the minimum security measures. However, its functionality is limited. Especially in the case of PCs used in companies, sufficient measures cannot be taken. In order to use your PC safely, it is recommended to install the most premium antivirus.
