Do Cloud Services Need Antivirus | Cloud Antivirus

Recently, cloud services have become familiar, haven't they?

Previously, I saved my documents on my PC and operated emails, websites, databases, etc. on my own server. Now that cloud services have become commonplace, all of these features are being replaced by cloud servers.

However, in order to introduce a new product, you need to understand the risks well.

First, I will explain the main risks of using the cloud.

so we often hear concerns about "cloud services". Antivirus is especially common. Services over the network inevitably carry the risk of viruses and unauthorized access, which are threats on the Internet.

So, this time, I would like to talk about antivirus measures that are of concern when using cloud services.

Attack on the Cloud

A problem these days is cyber attacks on servers. Not only cloud services but also corporate systems can be targeted by cyberattacks, but attack methods such as concentrating a large amount of access to paralyze communication and stealing information are used.

Although it is a risk that cannot be dealt with at the user level, cloud service vendors are taking various measures. Since the countermeasures of each vendor are published, please use it as a judgment standard at the time of introduction.

Not only cyber attacks but also disaster responses are properly taken by vendors. Similarly, countermeasures are open to the public, so please check when considering.

Viruses and Malware

A virus is a type of malware (malicious program) that can be executed and damaged without the user's knowledge.

Whether it is a cloud service or not, there is a risk that the virus will infect your local PC through email, websites, etc.

Many companies have installed cloud antivirus software depending on the infection route and the type of virus for cloud services, it also scans the data stored on the server.

Human Error

There are cases where account information is leaked due to improper management of account information or loss of a device, or data on the cloud is leaked due to incorrect file-sharing settings. There are measures such as strengthening account authority management, detecting abnormal access and suspending the account, and monitoring confidential information with DLP.

Exchange Online Protection (EOP)

Email is one of the gateways to malware intrusion. In some cases, the malware itself is attached to the email, but in other cases, spam emails can be used to promote access to the malware or become a gateway to phishing scams.

Exchange Online Protection (EOP) is equipped with spam filters, safe senders and rejected lists, IP addressing, content filters, etc., and has a quarantine function to detect and prevent unauthorized access.

Advanced Threat Protection (ATP)

Free antivirus software refers to a list of known viruses and detects matching programs like viruses, but it was difficult to deal with new viruses. Advanced Threat Protection (ATP) is an email filtering service that supports unknown viruses.
