It often feels that the threat of cyberattacks can only be combatted with fresh and advanced strategies. But that’s not necessarily true. As it turns out, a simple countermeasure could have prevented the infamous SolarWinds attack late last year.
That countermeasure isn’t anything new, either. It follows a decade-old security recommendation. If the victims of the attack just blocked all outbound connections from the servers running SolarWinds software, it would have rendered the malware hackers sneakily installed on those servers useless.
The revelation comes from a June 3 letter from the Cybersecurity and Infrastructure Security Agency (CISA) to Senator Ron Wyden, and highlights that, while increased spending in both the public and private sector is certainly necessary, good cybersecurity practices already exist.
