Amid the current government shutdown, over 80 government websites are either down or insecure. With no IT staff around to renew their TLS (Transport Layer Security) certificates, many government websites are being left open to vulnerabilities. Some of the sites are set up so that they become inaccessible to the public if their TLS certificates are not up-to-date. Yet, others simply warn users that the site is not secure, then allows you to bypass the warning and continue onto the site. Once on an insecure site, users will be vulnerable to man-in-the-middle attacks.
