How to protect devices from serious security issues


Zero days. If it sounds serious, that’s because it is.

“You have zero days to respond to this threat…this is where something was released, there is no known defence, no known fix,” explained CEO Dr. Chris Pierson from BlackCloak, a company that provides security defense for high-end networks. value of individuals and executives.

“These will be the biggest of the most well-known big vulnerabilities.”

Zero Day security issues have recently appeared on the iPhone, Google’s Chrome web browser, and Windows operating system.

That means software vendors have to scramble to release a patch. Otherwise, hackers can use the vulnerability to their advantage.

“They are going to target people who work in the intelligence sector, people who work in government journalists, corporate executives, people who work for defense industrial companies, these are the people most at risk,” Pierson said.

But ordinary people can also be affected.

“It happens all the time, it happens more often than you might think,” said Steve Tcherchian, chief information security officer at XYPRO Technology, a company that provides security software to financial institutions.

“You won’t be able to work, you won’t be able to make phone calls, your files could be locked potentially forever, your children’s photos, it’s all at stake,” Tcherchian said.

Hackers don’t even have to target you specifically. A website you visit may deliver malicious code to your devices.

The best way to prevent this from happening is simple: update your software.

“From your router to your smart devices, your kids’ computers, your kids’ phones, iPads, it all needs to be continually checked and updated…it may seem like a daunting task, but I’m telling you that the ‘alternative is not worth it,’ said Cherchian.

On iPhone, Android, Mac, and PC, there are two places to check: the operating system and the App Store. Be sure to back up all important files before updating.

iPhone: Go to Settings > General, then tap Software Update.

Android: Go to Settings > Software Update

Mac: Click the Apple menu in the upper left corner of your screen, then choose About This Mac. Then click on Software Update.

Windows: Search for “update” in the taskbar, then choose Check for updates. Tap Check for Updates again.

Chrome: Tap the three little dots in the upper right corner of the screen, then hover over Help, then click About Chrome. Chrome will check for updates. Reboot to install them.

For a more hands-on approach, enable automatic updates, which usually happen overnight.

“Installing these updates will ensure that you have the latest version of the software and that any vulnerabilities of which they are aware are properly patched and patched so that they can no longer be exploited,” concluded Cherchian.

Many people don’t install these updates because they don’t like features or settings to change. It’s understandable, but at the very least, make sure you install all critical security updates, even if you’re not upgrading the entire operating system.
