• Most cyberattacks are preventable, says AT&T

The majority of cyber attacks carried out against businesses stem from ‘known’ or common threats, according to research from AT&T.

The company’s report, called The CEO's Guide to Navigating the Threat Landscape, revealed that 90% of cyber attacks carried out last year came from ‘known’ threats, and therefore could have been prevented had the appropriate security measures been in place.

Mo Katibeh, senior vice president of advanced solutions, AT&T, said: "The daunting depiction of newly discovered security threats often gets attention from media and business leaders alike. But in fact, most attackers are targeting businesses using forms of attacks we already know about and can help defend against.

“In today's digital age, businesses need to remain vigilant about deploying and updating core security protections, and in educating employees on how their actions might impact the company's security."

In light of the report, businesses are advised to make sure that defences are in place to protect them against known threats such as ransomware. Creating a company culture in which staff are aware of cyber security risks and take action to mitigate them can also help to prevent avoidable hacks.

Organisations can also decrease their chances of falling victim to an attack by making sure that they’re up to date with security patches, software updates and keeping security concerns in mind when implementing new technologies.
