7. It was, as every year for years has been, a year of new records.
Cyber incidents targeting businesses nearly doubled from 2016 to 2017, driven by
ransomware and new attack methods.

93% of all breaches in 2017 could have been avoided with simple cyber hygiene
practices, such as regularly updating software, blocking fake email messages, and
training employees to recognize phishing attacks.

8. “I’ve told our entire team that our goal can’t be simply to fix the problem and move
on. Confronting cybersecurity risks is a daily fight. While we’ve made significant
investments in data security, we recognize we must do more. And we will”
— CEO Smith, Equifax
In 2020, organizations are expected to spend $101.6 billion on cybersecurity. Its 38%
increase from 2016
— The International Data Corporation (IDC)

9. What it means to us!
• Application security is becoming a mandatory skill for all roles in software industry
• New specialized opportunities are opening up
• Global Cybersecurity Skills Gap is increasing
“Cisco estimates that there are currently 1 million unfilled cybersecurity jobs worldwide,
while industry giant Symantec predicts that by 2019 the number will be 1.5 million”
