The most effective way to protect against malware is to ensure all software is up-to-date and has the latest security fixes. This can be difficult to manage on traditional operating systems with many software components from many vendors all with different update mechanisms and user interfaces. Chromebooks manage updates automatically so Chromebooks are always running the latest and most secure version.
One of the strengths of Chrome OS and Chromebooks is how easy Google makes it to sync your experience between devices using your Google account. Sign in to any Chromebook with your account and within minutes it's personalized from your bookmarks to apps to the wallpaper on your desktop. This also means a strong and unique password is essential for tight security.
If you share your Chromebook with friends and acquaintances, then you need to get acquainted with Guest mode. It lets someone use your Chromebook without being able to touch your Google account. Not only does it keep them from accessing your data and files, but it also prevents them from messing up your settings. A guest's browsing history, cookies, bookmarks and downloads will be trashed after they are done using your Chromebook and you exit Guest mode and log back into your account.
Go to Settings and click Screen lock and sign-in in the People section. Next, enter your password and toggle on Show lock screen when waking from sleep. If you have a long, complicated password that you'd rather not need to enter each time you wake up your Chromebook, select PIN or password and then click the Set up PIN button and choose a six-digit (or more) PIN that you can use instead of your password to unlock your Chromebook.

No matter how hard you work to secure that Chromebook, the security of that device is only as strong as the password used by the account holder. Not only should the account use a very strong, very unique password, it should make use of two-factor authentication (2FA). To setup 2FA, visit your Google Account Security page and enable 2-Step Verification (Figure A).
Next we want to prevent your browsing history from syncing to your Google account. To do that, type chrome://settings/syncSetup in the Chrome address bar. In the resulting page (Figure B), disable the entry for History.
Robust protection against ransomware (and many other threats) requires multiple layers of defense. The National Institute of Standards and Technology (NIST) outlines five main functions in the Cybersecurity Framework that serve as the primary pillars for a successful and comprehensive cybersecurity program in any public or private sector organization. Below are the recommendations from NIST and examples of how our Cloud technologies can help address ransomware threats:
Our CISO Guide to Security Transformation whitepaper outlines steps for a risk-informed, rather than risk-avoidance, approach to security with the cloud. A risk-informed approach can help you address the most important security risks, instead of addressing the risks that you already know how to mitigate. Cloud service providers make this risk-informed approach easier and more efficient for you by developing and maintaining many of the controls and tools that you need to mitigate modern security threats. Services like Cloud Asset Inventory provide a mechanism to discover, monitor, and analyze all your assets in one place for tasks like IT ops, security analytics, auditing, and governance.
Pillar #3 - Detect: Define continuous ways to monitor your organization and identify potential cybersecurity events or incidents. In the case of ransomware, this may include watching for intrusion attempts, deploying Data Loss Prevention (DLP) solutions to detect exfiltration of sensitive data from your organization, and scanning for early signs of ransomware execution and propagation.
During a ransomware attack or security incident, it's critical to secure your communications both internally to your teams and externally to your partners and customers. Many organizations with legacy Office deployments have shifted to Google Workspace because it offers a more standardized and secure online collaboration suite, and in the event of a security incident, a new instance can quickly be stood up to provide a separate, secure environment for response actions.
Protecting against ransomware is a critical issue for all organizations, and these questions and best practices are only the start of building a mature and resilient cybersecurity posture. It's important to remember that you can't focus on a single piece of defense; you need a comprehensive cybersecurity program that enables you to identify, prevent, detect, respond, and recover from threats. Above all, you need a range of solutions from a battle-tested and highly-resilient cloud platform that works across these elements in an integrated way with your business. To learn more about how Google Cloud can help you implement a comprehensive cybersecurity program to protect against threats like ransomware and more, visit our Google Cloud Security Best Practices Center.
Much like phones and tablets, there are now countless ways for malicious phishing links to be delivered. You could receive phishing messages on any apps from Google Hangout, WhatsApp to Facebook Messenger. Once you click on the link, attackers can steal your credentials or trick you into installing malicious Android or Chrome apps.
Apps for Chrome OS, as well as Android apps that work on Chromebooks, are just as susceptible to malware as apps for any other operating systems. Without elevated privilege to scan apps, antivirus for Chromebooks must look for the behaviors of a threat. By analyzing a large dataset of Chrome OS devices and apps, modern antivirus solutions can detect threats in new versions of apps to protect you from brand new viruses.
The last thing I would recommend is to set appropriate policies. There are malicious Chrome extensions out there. There was recently a proof of concept called the Cursed Chrome, which can take full control of your browser. To protect against these threats, I suggest putting together a list of pre-approved extensions that you allow your Chromebooks to install. This way, your users are much less likely to accidentally install malware.
Beware of relying on any piece of software, even your operating system, to protect you in all circumstances. A computer is only as smart as its user. And as a smart user, what are some strategies you should keep in mind to protect your Chromebook The following suggestions will keep your Chromebook from succumbing to adware, ransomware, spyware, or any other kind of malware you might encounter.
Employees working from seemingly secure remote locations have presented cybercriminals with easier targets on a much larger attack surface. With more of our valuable data being moved or generated online than ever before, cybersecurity can no longer be an afterthought. But not all of us are IT security experts, which is why it is important to have a laptop with built-in security features you can depend on.
New and more advanced cyberthreats are constantly emerging, which is why the best way to keep your data protected is by ensuring your computer is up to date with the latest security patches. The problem is that Windows updates can be annoying, disruptive, and sometimes even cause certain programs to stop working. Windows users also need to install additional third-party antivirus software, which can become costly and difficult to manage.
Chrome OS takes care of all of that for you, as updates happen automatically and silently in the background without slowing down the machine or inconveniencing users with long installation times. This means your Chromebook will always be protected from the latest security threats, without you having to lift a finger or wait for updates to finish before you can get back to work.
There should be no false illusions that Chrome OS is any different; it is not. The same tricks that are so successful on macOS can be equally effective on Chrome OS, and Malwarebytes has top-notch mobile malware researchers who work hard every day to keep Android and Chromebook users safe from such threats.But does my Chromebook really need antivirusSince there is, definitively, already malware that can affect Chromebooks, it's reasonable to install antivirus software on a Chromebook. And since Chromebooks are increasing in popularity, it's also reasonable to assume cybercriminals will continue to develop more malware to get their piece of the pie. Once Pandora's Box has been opened for a device, operating system, browser, or other platforms, we've never once seen the bad guys back away from it.
