CIS Controls® Implementation Group 1 (IG1): What It Means for Your Organization
CIS Controls® Implementation Group 1 (IG1) is the starting set of 56 Safeguards in the CIS Critical Security Controls®, version 8.1.
CIS Controls® Implementation Group 1 (IG1) is the starting set of 56 Safeguards in the CIS Critical Security Controls®, version 8.1.
The Center for Internet Security calls it “essential cyber hygiene,” the foundational set of cyber defense Safeguards every enterprise should apply to guard against the most common attacks. The CIS Controls are voluntary and free to use. In Texas, IG1 also matters for a specific reason: the SB 2610 cybersecurity safe harbor names it as part of the program requirements for businesses with at least 20 but fewer than 100 employees. ALCON DTS can help you assess against IG1, close the gaps and keep a record of the work.
The CIS Critical Security Controls® are, in CIS’s words, “a prescriptive, prioritized, and simplified set of best practices that you can use to strengthen your cybersecurity posture.” They are organized into 18 Controls, and each Control is broken into specific actions called Safeguards. There are 153 Safeguards in CIS Controls v8 and v8.1.
Not every organization needs to start with all 153. CIS sorts the Safeguards into three Implementation Groups (IGs), “based on the risk profile and resources an enterprise has available to them”:
CIS describes the typical IG1 enterprise as “small to medium-sized with limited IT and cybersecurity expertise,” with a limited tolerance for downtime. IG1 Safeguards “should be implementable with limited cybersecurity expertise and aimed to thwart general, non-targeted attacks.”
What changed in v8.1. CIS calls v8.1 “an iterative update to v8.” It updated alignment to other frameworks, revised asset classes and Safeguard descriptions, and added the “Govern” security function introduced in the NIST Cybersecurity Framework (CSF) 2.0. The IG pages list the same 56 IG1 Safeguards and 153 total Safeguards for v8 and v8.1.
It covers: the basics that stop common, non-targeted attacks. That means knowing your devices and software, protecting data, secure settings, accounts and access, patching, logging, email and browser protection, malware defense, backups, network basics, security training, service providers and incident response.
It is not:
No law requires most businesses to adopt the CIS Controls. IG1 becomes important in three common situations:
Quick check: does this apply to you?
If either is true, IG1 is very likely a good fit for you. Whether your program qualifies for the SB 2610 safe harbor is a legal question decided on the facts. Chapter 542 does not say how employees are counted. Confirm with your attorney.
IG1 has 56 Safeguards spread across 15 Controls. The table shows each Control, what it covers in plain terms and how many of its Safeguards are in IG1.
| CIS Control (v8.1) | What it covers | IG1 Safeguards |
|---|---|---|
| 1. Inventory and Control of Enterprise Assets | Know every device connected to your environment, on site, remote and in the cloud, and deal with unknown ones | 2 of 5 |
| 2. Inventory and Control of Software Assets | Know what software is installed, allow only authorized software, and find and remove the rest | 3 of 7 |
| 3. Data Protection | Identify, classify, securely handle, retain and dispose of data | 6 of 14 |
| 4. Secure Configuration of Enterprise Assets and Software | Set and maintain secure settings on devices and software | 7 of 12 |
| 5. Account Management | Manage user, administrator and service accounts | 4 of 6 |
| 6. Access Control Management | Create, assign, manage and revoke access and privileges | 5 of 8 |
| 7. Continuous Vulnerability Management | Track and fix vulnerabilities on all assets | 4 of 7 |
| 8. Audit Log Management | Collect, review and keep logs that help you detect and recover from an attack | 3 of 12 |
| 9. Email and Web Browser Protections | Protect against threats that arrive by email and the web | 2 of 7 |
| 10. Malware Defenses | Prevent or control malicious software | 3 of 7 |
| 11. Data Recovery | Keep recovery practices that can restore systems to a trusted state | 4 of 5 |
| 12. Network Infrastructure Management | Manage network devices so attackers cannot exploit weak services and access points | 1 of 8 |
| 13. Network Monitoring and Defense | Monitor and defend the network | 0 of 11 |
| 14. Security Awareness and Skills Training | Train your workforce to be security conscious and properly skilled | 8 of 9 |
| 15. Service Provider Management | Evaluate service providers who hold sensitive data or run critical platforms | 1 of 7 |
| 16. Application Software Security | Manage the security of software you build, host or acquire | 0 of 14 |
| 17. Incident Response Management | Prepare to detect and respond quickly to an attack | 3 of 9 |
| 18. Penetration Testing | Test your defenses by simulating an attacker | 0 of 5 |
| Total | 56 of 153 |
A practical path looks like this:
Texas Business and Commerce Code Sec. 542.004(a)(4) scales the program by employee count:
| Employees | What Sec. 542.004(a)(4) says | Where IG1 fits |
|---|---|---|
| Fewer than 20 | “simplified requirements, including password policies and appropriate employee cybersecurity training” | IG1 is not named for this tier. IG1’s account, access and training Safeguards can support the password and training elements |
| At least 20 but fewer than 100 | “moderate requirements, including the requirements of the Center for Internet Security Controls Implementation Group 1” | IG1 is named here |
| At least 100 but fewer than 250 | “compliance with the requirements of Subsection (b)” | IG1 is not named. Subsection (b) means conforming to one or more listed frameworks (the CIS Critical Security Controls are one, Sec. 542.004(b)(1)(E)), plus HIPAA, GLBA Title V, FISMA or HITECH if you are subject to them, and PCI DSS if it applies to you (Sec. 542.004(b)(2) and (3)) |
For every tier, the statute also says the program must contain administrative, technical and physical safeguards, “conform to an industry-recognized cybersecurity framework as described by Subsection (b),” and be designed to protect sensitive information (Sec. 542.004(a)(1) to (3)). The framework list in Subsection (b) includes “the Center for Internet Security Critical Security Controls for Effective Cyber Defense.” Talk with your attorney about how these parts of the statute work together for your organization.
You keep the compliance decisions. We run the controls. You decide which framework to follow and how much risk to accept. ALCON DTS can help you assess against IG1, run many of the Safeguards on the systems we manage and keep the evidence in one place.
| IG1 area | What ALCON DTS provides |
|---|---|
| Framework assessment and documentation | Compliance tracking against your chosen framework, with documented policies, procedures and an organized evidence file |
| Controls 1, 2 and 4: inventory and secure configuration | Device management, managed patching and updates, and automated documentation of systems and configurations |
| Control 3: data protection | Device encryption and protection on the systems we manage. Data inventory, classification and retention decisions stay with you |
| Controls 5 and 6: accounts and access | Identity and access with multifactor authentication and tight administrator rights; joiner, mover and leaver changes handled promptly; guest and vendor access kept under control |
| Control 7: vulnerability management | Managed patching and updates |
| Control 8: audit logs | Centralized logging and security monitoring through our Security Monitoring (SIEM) service, so you know what is logged |
| Control 9: email and web | Email security and filtering, plus email domain authentication |
| Control 10: malware defenses | Endpoint detection and response, application control and managed administrator rights |
| Control 11: data recovery | Tested backup and recovery |
| Control 12: network basics | Managed firewalls, switching and secure wireless networks |
| Control 14: training | Security awareness training with completion records |
| Control 15: service providers | A review of vendor access, with guest and vendor access kept under control |
| Control 17: incident response | Monitoring backed by our expert team. When an alert fires, the ALCON DTS expert team works the issue with you until it is back under control. |
The exact controls in your environment depend on your ALCON DTS plan and any project work, and we will show you which are in place today and which would close a gap. Some IG1 Safeguards, such as your data retention decisions and your incident response roles, are yours to own. ALCON DTS does not certify organizations against the CIS Controls, and whether the SB 2610 safe harbor applies to a claim is a legal question.
Want to know where you stand against IG1? We will compare your current controls with the 56 IG1 Safeguards and show you what would close the gaps.
