K-12 Cybersecurity Attacks Mounting
- By Dian Schaffhauser
A study of data available from various security incident-tracking resources found that there have been 301 reported cybersecurity attacks against schools so far this year, compared to just 124 in 2018. However, that number would be much higher if it were possible to include other cases that "went either unreported or even undetected," according to security company Barracuda Networks, which released the analysis.
According to the company's security researchers, which examined data related to 721 incidents reported since January 2016 and tallied by the K-12 Cybersecurity Resource Center, the most common types of threats targeting schools fell into five categories:
- Data breaches (31 percent);
- Malware (23 percent);
- Phishing (13 percent);
- Network or school infrastructure hacks (10 percent); and
- Denial-of-service attacks (4 percent).
Another 16 percent of security events involved accidental disclosure of data; and 3 percent were classified as "other."
Phishing was of special interest to the researchers as a type of security problem that often goes unreported by schools unless "an incident occurs as a result or the campaign is large enough to warrant attention." In the United States, the company noted, 5 percent of the phishing incidents reported to the Resource Center were W-2-related. Another area of concern: phishing that was intended to "scam" the school or district, which made up 4 percent of the total attacks and struck individuals or districts to the tune of thousands of dollars per incident.
Barracuda offered advice in its report:
- First and foremost, invest the money to put a "full" perimeter security portfolio in place, including "network firewalls, web filters, e-mail protection and application firewalls."
- Stay on top of internal security, such as intrusion detection, data backup and anti-malware programs, and especially keep up with security patches.
- Adopt incident response functionality to help when a security incident takes place and to isolate and remediate the problems.
- Finally, invest in "capable IT security staff" or put in place managed services that can deliver this expertise to the school or district.
The complete analysis is openly available on the Barracuda website.
