Virus is okay !? IPad security measures that can be done immediately-iPad computerization course

The App Store only publishes apps that Apple considers to be a security issue.

2) Sandbox mechanism On the iPad, apps made by other companies and data created by those apps are saved in a dedicated area called "sandbox". Behavior in a sandbox is designed to be unaffected by another sandbox, so even if it contains a virus, it will be quarantined in the sandbox and will not affect other apps or OS. (There is no antivirus software for the iPad because it cannot scan the data in the sandbox).

Note that it is not 100% safe

However, although the iPad (similarly the iPhone) has a low risk of viruses, there are some parts that cannot be said to be "absolutely safe." This is because there have been several incidents in the past where the "thick walls" of the App Store and sandboxes have been broken.

Regarding the App Store, an app containing a virus called "Xcode Ghost" was released in September 2015 after passing through Apple's review. Since it was an App Store in China, it had little impact on Japan, but it was a big news because it shook the safety myth of the App Store.

Also, in October 2019, security company Wandera announced that it had found 17 malware-infected apps on the App Store. Apple immediately removed and updated its security tools on Trojan horses that perform ad fraud-related tasks in the background, such as repeatedly visiting web pages and clicking links.

In addition, security maker Norton has a mechanism that the concept of sandbox was established on the company's website more than 20 years ago, and malware that tries to avoid detection by sandbox has appeared for personal computers, so it is versatile. It explains that it is not. In addition, there have been cases where a virus was sent when connecting to a Mac or Windows PC to back up an iPad or iPhone. It's a good idea to understand that the iPad is "relatively safe for now" and take steps to minimize its risk.

Measures to reduce the risk of viruses

1) Keep your iPad OS and apps up-to-date The latest versions of iPad OS and third-party apps released regularly by Apple have vulnerabilities and the latest security measures, so be sure to install them. Let's use it.

2) Don't install apps from other than the App Store Although the App Store has proven to be incomplete in the past, it's still the safest place to get apps for the iPad. Normally, the iPad has a mechanism that allows you to install apps only from the App Store, but you can also install custom apps for business use directly without going through the App Store. Others try to improperly control the device by inducing them to install a configuration profile instead of an app. Never install it unless you can be sure that the publisher is safe.

3) Be careful when connecting to a Mac or Windows PC Install security software on your Mac or Windows PC and try to keep it virus-free so that it will not be infected when you connect your iPad. Also, refrain from connecting to untrusted other people's Macs and Windows PCs.

4) Do not connect to unreliable networks There are various Wi-Fi spots in the city, but some of them have no service provider. The Wi-Fi network name can be easily changed, so it's possible that you're daring to disguise it as a trusted company name. Be aware that connecting to such unreliable Wi-Fi does not mean that you will be infected with a virus, but the chances are not zero.

5) Beware of fake warnings and suspicious links Avoid accessing suspicious sites on your iPad. Some of them will display a fake warning message like "Apple security virus detected!" The moment you visit the site, and press the "To get rid of malware" button to install the countermeasure tool. May be prompted. If you accidentally press the button, you will be directed to a malicious site and there is a risk of security damage. If you see such a pop-up, close the site immediately. Also, be careful not only on the internet but also on suspicious links via email or SNS.

Be careful other than viruses

If you follow these basic precautions, you don't have to be overly afraid of viruses on your iPad, which is inherently secure. Rather, the iPad should look at non-virus threats that many people are likely to suffer. Of particular note is the damage caused by online fraud such as phishing for the purpose of fraudulent income of money and account information. That's why most of the security software released for iPad has a function to detect malicious sites, dangerous emails and SMS.

In addition, other security measures for iPad include protection from theft and snooping, account management such as ID / password, and measures against leakage of personal information and privacy. Let's take a closer look next time, including measures against phishing scams.
