This is a minor patch to improve upon findings in version 2.3.0.

Changes:

Convert all skipped tests to uppercase

Updated French translation
Exclude custom.prf from tarball (download via website)

Lynis 2.3.0 (2016-07-13)

We are excited to announce this major release of auditing tool Lynis. Several big changes have been made to core functions of Lynis. These changes are the next of simplification improvements we made. There is a risk of breaking your existing configuration. See the tips below to upgrade.

This release will soon also be available in our software repository. For more details see https://packages.cisofy.com to install and upgrade Lynis.

Upgrade tips

Default profile and custom profiles: Settings of multiple profiles can now be merged. Instead of making changes to default.prf, copy your changes to custom.prf. Use 'lynis show profiles' to show any detected profiles. Only include your changes in custom.prf, to keep the configuration clean and tidy. They will then overwrite the defaults. Use 'lynis show settings' to see if they are applied.

Check your cron jobs: When using --quiet, the output will be really quiet now. Use --show-warnings-only if you still want to see the warnings. Lynis will now exit with error 0, even when warnings have been found. Use option error-on-warnings=yes (custom.prf) to exit with code 78 when it has any warnings.

Details

Ansible

New Ansible examples for deployment: https://github.com/CISOfy/lynis-ansible

Databases

Lynis will check also for DB2 instances and report the status.

Developer Mode

With this release the developer mode is introduced. It can be activated with the --developer option, or developer-mode=yes in profile. In development mode, some details are displayed on screen, to help testing of existing or new tests.

To get easy access, a new profile has been added (developer.prf).

Examples: lynis audit system --profile developer.prf lynis audit system --developer

A new software development kit (SDK) for Lynis is available on GitHub. This will help contributors and developers to test software quality, including linting and running unit tests. The devkit also supports building DEB and RPM files for easy deployment. The repository can be found on https://github.com/CISOfy/lynis-sdk

Documentation

Template files have been updated to provide better examples on how to create custom tests and plugins.

To simplify the usage of Lynis, a new helper utility has been added: show. This helper will show help, or values (e.g. version, plugin directories, etc). Some examples include: lynis show options, lynis show commands, lynis show version, etc. See lynis show for all available details.

File Systems

The XFS file system detection has been added. Mount points /dev/shm and /var/tmp are now checked for their options. Comparison of the mount options has been improved. A new test has been added to check if /var/tmp has been bound to /tmp.

Language Support

Lynis now supports language translations, with the language profile option. Initial languages: Dutch (nl), English (en), French (fr).

You can help by translating the language files in the db directory.

Mac OS X Improvements

Package manager Brew has been added

nginx

Show suggestion when weak protocol is used, like SSLv2 or SSLv3. The protocols are now also parsed and stored as details in the report file.

Packages

Systems running CentOS, Debian, openSUSE, RHEL, Ubuntu and others, may now use our own software repository: https://packages.cisofy.com

Performance

Several performance improvements have been implemented. This includes rewriting tests to invoke less commands and enhanced hardware detection at the beginning.

Plugins

You can set the plugin directory now also via a profile. First match wins. Priority: 1) argument, 2) profile, 3) default

--plugindir is now an alias for --plugin-dir

Profiles

Lynis now support multiple profiles. By using a file 'custom.prf', it allows to inherit values first from default.prf, then merge it with custom.prf.

Several tests have been altered to support multiple profiles.

New profile options: quick=yes|no (similar to --quick) developer (see Developer section) check-value

Remote scanning

Although Lynis is a aimed on running on local hosts, there is still an ongoing demand for running remote scans. With 'lynis audit system remote' tips are now provides to perform such a scan via SSH.

Software

Zypper calls are now marked with a non-interactive flag to prevent it waiting for any interactive input.

Solaris

Improve execution for Solaris systems.

SSH

The configuration of SSH is now parsed from the SSH daemon directly. This enables handling with new defaults more easily, as OpenSSH sometimes introduces new keys, or change their default value between versions.

Systemd

Added support for detecting systemd and reporting it as a service manager. The systemd plugin has been released as a community plugin.

Uploads

Solved a bug which added the proxy configuration twice.

Profile options: upload-tool and upload-tool-arguments

General Improvements

The screen output has been improved, to show more meaningful things when some parameters are missing. Several old variables and lines have been cleaned up.

The Display function now allows the --debug flag. This helps in showing some lines on screen, which would normally be hidden (e.g. items not found or matched).

Logging has been improved in different areas, like cleaning up and add more relevant messages where needed.

The interface colors have been changed, to make it more obvious how the software can be used. Also the wait line between categories have been altered, to properly display on systems with a white background.

When no auditor name has been specified, it will say that instead of unknown.

Functions file has been cleaned up, including adding developer debug information when old functions are still be used. Later on these functions will be deleted, and therefore placed at the bottom.

Lynis 2.2.0 (2016-03-18)

We are proud to present this new release of Lynis. It is a major upgrade, and the result of many months of work. This version includes new features and tests, and many small enhancements. We encourage all to test and upgrade to this latest release.

Highlights

The biggest change in this release is the optimization of several functions. It allows for better detection, and dealing with the quirks, of every single operating system. Some functions were fortified to handle unexcepted results better, like missing a particular binary, or not returning the hostname.

This release also enables tests to be shorter, by adding new functions. Some functions were renamed or slightly changed, to provide more value to the tooling. Another big change in this release is a wide set of optimizations and quality testing. Outdated pieces were removed, or rewritten, to support features seen in newer distributions.

In the area of compliance, adjustments have been made to start supporting more in-depth testing for this. Ideal for companies who have a particular compliance need, or want to test and enforce the system hardening levels of their systems.

Last but not least, many small changes make this software easier to use. On our website we added new guides to provide help and support.

We like to thank our contributors, in particular Kamil Boratyński, Steve Bosek, and Eric Light. Their contributions helped us greatly shaping this release.

Below are the changes per category:

Automation tools

Detection for CFEngine has been improved. Also additional logging and reporting of automation tools.

Authentication

Depending on the operating system, Lynis now tries to determine if failed logins are properly logged. This includes checking for /etc/login.defs file [AUTH-9408]. Merged previous password check for Solaris into test AUTH-9228. User ids on AIX will be gathered and added to the report [AUTH-9234].

New plugin is introduced to analyze PAM settings. It including items like:

Two-factor authentication methods
Minimum password length, password strength and protection status against brute force cracking
Password history

Report option: auth_failed_logins_logged

Boot

Added detection for Mac OSX boot loader. Initial support to test UEFI settings, including Secure Boot option. Options boot_uefi_booted and boot_uefi_booted_secure added to report file

Compliance

This release prepares for upcoming extensions to assist with compliance testing. The profile has a new option, which can be used to define what standards should be tested for, if any test is available. The related option is: compliance_standards

Right now these standards can be selected:

CIS benchmarks
HIPAA
ISO27001/ISO27002
PCI DSS

Note that additional tests will be implemented in future releases and then tagged to these particular standards.

DNS and Name services

Support added for Unbound DNS caching tool [NAME-4034], including a configuration check [NAME-4036].

Record if a name caching utility is being used like nscd or Unbound. Also logging to report as field name_cache_used

Firewalls

Test for IPFW firewall on FreeBSD has been improved: status of pflogd will no longer be displayed, when pf is not available.

New test FIRE-4532 introduced for detection of the Mac OS X application firewall. Also, the status of application firewalls is audited now.

FIRE-4508 is another new test, which tests chains of iptables and their default policy (ACCEPT or DROP). This release also supports the upcoming nftables technology with new test FIRE-4536. It is expected that it will replace iptables later on, so this test will perform a status check. Additional FIRE-4548 will perform a version detection of the userland utility nft and determine if there are any rules configured.

Renamed FIRE-4511 to FIRE-4502.

File Integrity Monitoring

Test added to include osqueryd as a supported tool.

Hardware

Detection of firewire is enhanced (both ohci and core detected).

Logging

Extended the test syslog-ng logging to remote systems. The log Lynis itself produces is also enhanced, to be more detailed for several tests.

Malware

ESET and LMD (Linux Malware Detect) have been added. Discovered malware scanners are also logged to the report.

Mount points

FILE-6374 is expanded to test for multiple common mount points and define best practice mount flags.

Networking

Best practices for IPv6 configuration on Linux are now collected. Also network interface names from most operating systems.

Operating systems

Improved support for Debian 8 systems, and displaying Gentoo for Gentoo-based systems. Detection of VMware release has been added. Boot loader exception is not longer displayed when only a subset of tests is performed. FreeBSD systems can now use service command to gather information about enabled services.

Several paths have been added to allow better detection on systems running FreeBSD and others.

Passwords

AUTH-9286 change has been extended to both capture minimum and password age.

Proxy support

A proxy can now be specified in the profile, to allow uploads via a HTTP or SOCKS proxy.

Service Managers

SystemV init is now detected.

Software and Packages

Now information will be logged when vulnerable software packages were found. Support for DNF (Dandified YUM) for Fedora systems has been added. This is done in several tests: PKGS-7350 (installed packages), PKGS-7352 (security notices), PKGS-7354 (integrity tests).

SSH

Multiple configuration tests of SSH are now merged into SSH-7408. This enables easier testing later on and reduces repetition.

Virtual machines and Containers

Detection of virtual machines has been extended in several ways. Now VMware tools (vmtoolsd) are detected and machine state is improved with tools like Puppet Facter, dmidecode, and lscpu. Properly detect Docker on CoreOS systems, where it before gave error as it found directory /usr/libexec/docker. Check file permissions for Docker files, like the socket file [CONT-8108].

Individual tests

[AUTH-9204] Exclude NIS entries to avoid false positives [AUTH-9230] Removed test as it was merged into AUTH-9228 [AUTH-9234] Support for AIX added [AUTH-9288] Test for expired passwords [AUTH-9328] Show correct message when no umask is found in /etc/profile.

The first release within the 2.x branch! It includes several new features, to simplify or improve auditing on Unix based systems, including BSD, Linux, Mac OS and more traditional systems like AIX, HPUX and Solaris.

New features and many improvements are the reason for the bump to a major release, also a beginning of a new era. Many tools to audit or harden systems have being released, yet none have been maintained over a long period of time.

Lynis Support and Feedback

This software is supported and under development by CISOfy. By providing a dual license, this software is kept up-to-date and enhanced. Both customers and the community, benefit from this licensing. This release is available thanks to your input and feedback.

Lynis Helpers

New in this release is the support for helpers. Small utilities which enhance Lynis by providing a single goal. The first helper available is to audit Docker build files.

Lynis Improved OS support

Many changes have been implemented to better support Linux, FreeBSD, NetBSD DragonBSD and OpenBSD in particular. Upcoming releases will include smaller "improvement rounds" for other systems as well.

Lynis New technologies

More utilities and technologies are supported now. Technologies and tools like systemd, Docker, nftables.

Lynis Lynis Enterprise

As this code is shared, customers have an additional option to define to what server they want to upload the audit results. Also, commercial plugins have been bundled.

Lynis New parameters

Several new options have been added:

--dump-options (see all options)
--report-file (define a different location for the report file)

Lynis General

Documentation on the website has been extended: https://cisofy.com/support/ The man page, Lynis binary and several tests have improved texts.

This release is exceptional in that it includes many changes. We have done a lot of testing on different platforms. You could expect this software to be stable. Still, an assumption is no guarantee and especially no substitution for testing in your own environment. If you encounter issues, please report them via one of the links above in this changelog.
