Systems Affected by OpenSSL
Overview
Brief notes about compiling Apache and Openssl stand-alone on /usr/local/, on SUSE 15 SP3. Previously Apache was installed on top of the binaries installed by the SUSE packages. However, that method disabled the possibility of using the newest OpenSSL libraries; because updating OpenSSL would break other system utilities. Hence, compiling stand-alone in /usr/local/.

Overview
Brief notes on how to install and run tripwire on SuSE Enterprise Linux SLE 15. Tripwire checksums critical files in a database. Afterward you can inspect the checksum for files that have changed or files that have been breached. So for example, files in /bin/ should never change unless an upgrade was performed; Tripwire can scan daily for delicate files changed; a good security intrusion detection software.
