Testing results

Note There are discrepancies between different CIS sources. After a meeting with @72nomada, we have agreed to use https://www.cisecurity.org/controls/cis-controls-navigator for compliance verification. However, for this testing, we have used the sources specified in the preconditions section. So we should check manually every compliance detected error, especially ISO values.

Preconditions ### Compliance review Compliance validation has been performed using the following CIS mapping: - **PCI DSSV3.2.1**: https://learn.cisecurity.org/CIS-Controls-and-Sub-Controls-Mapping-To-PCI-DSS-v1.0-excel - **PCI DSSV4.0**: https://learn.cisecurity.org/CIS-Controls-v8-Mapping-to-PCI-DSS - **SOC2**: https://learn.cisecurity.org/CIS-Controls-v8-SOC2-Mapping - **HIPAA**: https://learn.cisecurity.org/CIS-Controls-v8-HIPAA-Mapping - **ISO**: https://learn.cisecurity.org/controls-sub-controls-mapping-to-ISO-v1.1.a - **NIST_800_53**: https://learn.cisecurity.org/CIS-Controls-v8-nist-sp-800-53-mapping - **CMCv2**: https://learn.cisecurity.org/CIS-Controls-v8-Mapping-to-CMMC

Since the /var directory may contain world-writable files and directories, there is a risk of resource exhaustion. It will essentially have the whole disk available to fill up and impact the system as a whole. In addition, other operations on the system could fill up the disk unrelated to /var and cause unintended behavior across the system as the disk is full. See man auditd.conf for details. - Fine grained control over the mount: Configuring /var as its own file system allows an administrator to set additional mount options such as noexec/nosuid/nodev. These options limits an attackers ability to create exploits on the system. Other options allow for specific behavior. See man mount for exact details regarding filesystem-independent and filesystem-specific options. - Protection from exploitation: An example of exploiting /var may be an attacker establishing a hard-link to a system setuid program and wait for it to be updated.

Since the /var/tmp directory may contain world-writable files and directories, there is a risk of resource exhaustion. It will essentially have the whole disk available to fill up and impact the system as a whole. In addition, other operations on the system could fill up the disk unrelated to /var/tmp and cause potential disruption to daemons as the disk is full. - Fine grained control over the mount: Configuring /var/tmp as its own file system allows an administrator to set additional mount options such as noexec/nosuid/nodev. These options limits an attackers ability to create exploits on the system. Other options allow for specific behavior. See man mount for exact details regarding filesystem-independent and filesystem-specific options. - Protection from exploitation: An example of exploiting /var/tmp may be an attacker establishing a hard-link to a system setuid program and wait for it to be updated. Once the program was updated, the hard-link would be broken and the attacker would have his own copy of the program. If the program happened to have a security vulnerability, the attacker could continue to exploit the known flaw.","remediation":"For new installations, during installation create a custom partition setup and specify a separate partition for /var/tmp.

It will essentially have the whole disk available to fill up and impact the system as a whole. In addition, other operations on the system could fill up the disk unrelated to /var/log/audit and cause auditd to trigger it's space_left_action as the disk is full. See man auditd.conf for details. - Fine grained control over the mount: Configuring /var/log/audit as its own file system allows an administrator to set additional mount options such as noexec/nosuid/nodev. These options limit an attacker's ability to create exploits on the system. Other options allow for specific behavior. See man mount for exact details regarding filesystem-independent and filesystem-specific options. - Protection of audit data: As /var/log/audit contains audit logs, care should be taken to ensure the security and integrity of the data and mount point. ``` - **Remediation**: :green_circle: - **Impact**: :black_circle: - **Compliance**: :red_circle: - **CIS ID**: :green_circle: - **CSC**: :green_circle: - **ISO**: :red_circle: - **CMMC**: :black_circle: - **SOC**: :green_circle: - **NIST**: :green_circle: - **PCI**: :green_circle: - **MITRE**: :green_circle: ISO: No mapped iso value for CIS 8.3 - **References**: :green_circle: - **Rules**: :green_circle:

Since the /home directory contains user generated data, there is a risk of resource exhaustion. It will essentially have the whole disk available to fill up and impact the system as a whole. In addition, other operations on the system could fill up the disk unrelated to /home and impact all local users. - Fine grained control over the mount: Configuring /home as its own file system allows an administrator to set additional mount options such as noexec/nosuid/nodev. These options limit an attacker's ability to create exploits on the system. In the case of /home options such as usrquota/grpquota may be considered to limit the impact that users can have on each other with regards to disk resource exhaustion. Other options allow for specific behavior. See man mount for exact details regarding filesystem-independent and filesystem-specific options. - Protection of user data: As /home contains user data, care should be taken to ensure the security and integrity of the data and mount point.","remediation":"For new installations, during installation create a custom partition setup and specify a separate partition for /home.

Testing results - Second review

During first review it was used an automated script to check compliance data. A bug was introduced and the pci_dss_3.2.1 value was not correctly validated. In this second review, it details every check that includes wrong pci_dss_3 values

1.1.2.1 :red_circle: **Expected**: `['1.2.1', '2.2.2', '2.2.5']` **Current**: ` ["1.1.6", "1.2.1", "2.2.2", "2.2.5"]`
1.1.2.2 :red_circle: **Expected**: `['1.2.1', '2.2.2', '2.2.5']` **Current**: ` ["1.1.6", "1.2.1", "2.2.2", "2.2.5"]`
1.1.8.1 :red_circle: **Expected**: `['1.2.1', '2.2.2', '2.2.5']` **Current**: ` ["1.1.6", "1.2.1", "2.2.2", "2.2.5"]`
1.2.2 :red_circle: **Expected**: None **Current**: `["6.2"]`

Testing results - Second review

As @jk-olaoluwa has noticed here pci_dss_3.2.1 values were correct. In the first review, I used v7 compliance mapping instead of v8 due to a misunderstood.

Note In this second review it was also included a detected error in the 28004 check compliance order as a result of this issue

1.1.3.1 :red_circle: - **Compliance**: Wrong compliance values order. NIST should be placed after the cis_csc_v7 value and before ISO.
1.1.5.1 :green_circle: - **Description**: :green_circle:
1.1.6.1 :green_circle: -**Rationale**: :green_circle:
1.1.8.1 :green_circle: - **References**: :green_circle:
1.2.2 :red_circle: - **Remediation**: Currently, it Is mandatory to include a`.` at the end of each section, even if it is a remediation command. If this is not expected, we should remove the `.` from all of the checks

1.1.3.1 🔴 - Solved 1.2.2 🔴 - We are going to let the semi-colon, there is no need for full stop.

Testing results - Third review

All checks seem to be correct. The compliance order will be fixed in the last RHEL 9 SCA Policy commit. For now, the wrong compliance order should not be considered a failure.

Closing conclusion 👍🏼

The requested changes have been applied and appear to be working correctly.

Good work to both of you 😄
