How to back up your Gmail: The ultimate guide.AWS: Here's what went wrong in our big cloud-computing outage.We urge all organizations to join us in this essential effort and take action."Īdditional steps recommended by CISA include: enumerating any external facing devices with Log4j installed ensuring the security operations center actions every alert with Log4j installed and installing a web application firewall (WAF) with rules to focus on Log4j. "We will only minimize potential impacts through collaborative efforts between government and the private sector. "To be clear, this vulnerability poses a severe risk," CISA director Jen Easterly said Sunday. But it also recommends setting up alerts for probes or attacks on devices running Log4j.
