- Configuration Management
- Change Management
- Data Management
- Identity and Acccess Management
- Incident Response
- Mobile Device Management
- Network Operations
- People Resources
- Risk Management
- System Design Documentation
- Security Governance
- Service Lifecycle
- Systems Monitoring
- Site Operations
- Training and Awareness
- Third Party Management
- Vulnerability Management

Download CIS Benchmark pdf files for each product (Amazon Linux, MongoDB, etc.) from:
PROTIP: View the “Distribution Independent Linux Benchmark” first because Benchmarks specific to a Linux distribution repeat much of its contents.
Download and review “Measures and Metrics” pdf and excel:
CIS Security Benchmarks for Linux
These are common asset items to be protected, as addressed by CIS Benchmarks across several Linux distributions:
Initial setup 1.1. Filesystem Configuration 1.2. Configure Software Updates 1.3. Filesystem Integrity Checking 1.4. Secure Boot Settings 1.5. Additional Processing Hardening 1.6. Mandatory Access Control 1.7. Warning Banners
Services 2.1. inetd Services 2.2. Special Purpose Services 2.3. Service Clients
Network Configuration 3.1. Network Parameters (Host Only) 3.2. Network Parametres (Host and Router) 3.3. IPv6 3.4. TCP Wrappers 3.5. Uncommon Network Protocols 3.6. Firewall Configuration
Logging and Auditing 4.1. Configure System Accounting (auditd) 4.2. Configure Logging
Access, Authentication, and Authorization 5.1. Configure cron 5.2. SSH Server Configuration 5.3. Configure PAM 5.4. User Accounts and Environment
System Maintenance 6.1. System File Permissions 6.2. User and Group Settings
Under each sub-item above are specific recommendations with Bash script commands to implement them out and commands to audit whether they have been implemented. That code is incorporated in the “CIS-CAT Lite (CIS Configuration Assessment Tool)” below.
Items in the Benchmark described as (Scored) indicates when compliance with the given recommendation impacts the assessed target’s benchmark score. Failure to comply with “Scored” recommendations will decrease the final benchmark score. Compliance with “Scored” recommendations will increase the final benchmark score. Compliance on “(Unscored)” items make no difference to the total score.
Compliance scores go to 100.

CIS states the status of the above Control Measures as the percentage among all the organization’s assets. But CIS doesn’t weight some parts of the organization more over others.
CIS borrows from Statistics for the area under the curve at integer levels of Standard Deviation (called a Sigma). CIS scores are named “Sigma Level One” to “Sigma Level Six”, with One at 69% or Less 31% or Less 6.7% or Less 0.62% or Less 0.023% or Less 0.00034% or Less
PROTIP: Also identify and count the base of consideration whether controls are applicable. A control may not be applicable to every item or organizational role assessed. Such are a separate set of calculation not addressed by CIS but need to be considered nonetheless to measure progress toward assessment completion.
The above form the basis for Security Implementation Plans provided by services vendors such as GuidePoint. Such plans sequence work so that technical and organizational dependencies among tasks are achieved in the appropriate order.
- Make a full backup of your machine before starting this procedure.
Request an email to download the free “CIS-CAT Lite (CIS Configuration Assessment Tool)” at https://learn.cisecurity.org/cis-cat-lite (file CIS-CAT Lite v3.0.56.zip).
“CIS-CAT Lite provides a fast, detailed assessment of your system’s conformance with CIS Benchmarks for Windows 10, Mac OS, Ubuntu, and Google Chrome. Simply run the tool,receive a compliance score (1 - 100) and quickly view remediation steps for non-compliant settings.”
Expand downloaded file “CIS-CAT Lite v3.0.56.zip” to folder cis-cat-lite.
- Read the CIS-CAT Users Guide.pdf (104 pages).
- Install a JVM because the CISCAT.jar is Java-based.
- Move the folder under “temp” or other folder of your choice. Change to that directory.
On a Mac, open a Terminal and run CIS-CAT.sh
chmod CIS-CAT.sh ./CIS-CAT.sh
Alternately, run CIS-CAT.BAT on Windows machines.
- Click “Accept” to the pop-up GUI.
Click “Benchmark” to select from the pull-down.
There is also the LiteCIS-CAT Pro (for paid members) which covers CLI as well and provides more Benchmark items to scan (for a price).
Select “CIS_Apple_OSX_10.12_Benchmark” even if you have a more recent version.
View the misc folder benchmarks.txt to see this list:
- Click “Next”.
- Selet Profile Level 1.
- Notice that the report goes to your user home folder, not your present Working Directory containing the program.
- Click “Next” then “Start Assessment”, and watch the progress scroll by.
- Click “View Reports”.
- Exit the program.
- Click on the Benchmark link associated with a number in the “Fail” column.
- Assess each Fail.
Some people prefer to hold off on automatic updates until hearing if early adopters experienced problems. The risk is fending off “zero day” security issues.
2.2.2 Ensure time set is within appropriate limits
The default NTP server is
sudo ntpdate -sv time.apple.com
However, the ntpdate tool was removed in macOS Mojave 10.14 because the
ntpd daemon since Mavericks (10.9) and Yosemite (10.10) is no longer responsible for adjusting the time. and instead a new program pacemaker has been introduced — so how can I know things are working or need adjustment to keep time?
sudo sntp -sS pool.ntp.org
2.4.3 Disable Screen Sharing
CIT Fails thinking that Screen Sharing is enabled. But in System Preferences, Sharing, only Printer sharing is selected.
3.1.1 Retain system.log for 90 or more days
/etc/asl.conf to change from
> system.log mode=0640 format=bsd rotate=seq compress file_max=5M all_max=50M
> system.log mode=0640 format=bsd rotate=utc compress file_max=5M ttl=90
Add for 3.1.2 Retain appfirewall.log for 90 or more days
> appfirewall.log mode=0640 format=bsd rotate=utc compress file_max=5M ttl=90
3.1.3 Retain authd.log for 90 or more days
sudo vim /etc/asl/com.apple.authd
Replace or edit the current setting
* file /var/log/authd.log mode=0640 compress format=bsd rotate=seq file_max=5M all_max=20M
with a compliant setting:
* file /var/log/authd.log mode=0640 format=bsd rotate=utc compress file_max=5M ttl=90
3.2 Enable security auditing
sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.auditd.plist
RESPONSE: /System/Library/LaunchDaemons/com.apple.auditd.plist: service already loaded
3.5 Retain install.log for 365 or more days
* file /var/log/install.log format='$((Time)(JZ)) $Host $(Sender)[$(PID)]: $Message'
* file /var/log/install.log mode=0640 format=bsd rotate=utc compress file_max=5M ttl=365
5.1.1 Secure Home Folders
Run one of the following commands in Terminal, substituting user name:
sudo chmod -R og-rwx /Users/username sudo chmod -R og-rw /Users/username
RESPONSE: chmod: Unable to change file mode on /Users/wilsonmar/projects/WM/bin/jad.readme.txt: Operation not permitted
There is also a Docker CAT: https://www.cisecurity.org/benchmark/docker/

In the US federal government, the Federal Information Security Management Act of 2002 (FISMA) is a law implented according to National Institute of Standards and Technology (NIST) Special Publication (SP) 800-53 [pdf].
In 2011 a “cloud first” policy was defined in the Federal Risk and Authorization Program (FedRAMP) [pdf] where federal agencies make use of cloud service providers (CSPs) given authority to operate (ATO) after receiving system authorization from an independent security assessment conducted by a 3PAO (third-party Assessor).
A System Security Plan (SSP) is required by the OMB Security Authorization of Information Systems in Cloud Computing [pdf].
Coalfire came up with this count of controls:
FedRAMP added 144 control to 728 in FISMA, for a total of 872 controls.
DISA SIST & SRG
Security Technical Implementation Guides (STIGs) [Wiki] defines (over 425) “lock down” configuration settings to minimize vulnerabilities to malicious attack of DOD IA (Information Assurance) and IA-enabled devices/systems, both Windows and Apache Unix. Cloud Computing Security Requirements Guide (CC SRG) are also defined by DISA (Defense Information Systems Agency) which provides a Viewer to scan for them.
SCAP (ecurity Content Automation Protocol) [Wikipedia] checklists enable automated vulnerability management, measurement, and policy compliance evaluation of systems deployed in an organization. See the 2015 viewer video.
See https://www.open-scap.org/ for tools.
