SSP vs POAM: Understanding Key Cybersecurity Differences


Updated on:

my main goal is to ensure that my clients are protected against the ever-evolving threat of cyber attacks. One common question I get asked is what is the difference between SSP and POAM and which is better? It’s essential to understand these two key cybersecurity concepts to improve your organization’s overall security posture. In this article, I’ll give you everything you need to know about SSP and POAM and why they matter so much in cybersecurity. So fasten your cybersecurity seatbelts, and let’s dive in!

What is the difference between an SSP and a POAM?

An SSP and a POAM are both critical components of maintaining a secure system, but they serve different purposes. An SSP, or System Security Plan, is a living and working document that outlines how your system is secured and protected. On the other hand, a POA&M, or Plan of Action and Milestones, is a document that identifies any vulnerabilities or weaknesses in your system and outlines a plan to address them. It serves as a roadmap to track your progress towards resolving those issues.

Here are some key differences between an SSP and a POA&M:

  • An SSP is a proactive document that outlines your system’s security posture, while a POA&M is reactive and identifies areas that need improvement.
  • An SSP is comprehensive and ongoing, including information about system design, configuration management, incident response procedures, and more, while a POA&M is specifically focused on identifying and resolving vulnerabilities.
  • An SSP is typically created by the system owner or administrator and updated regularly, while a POA&M is often the responsibility of the security team or compliance officer and is typically updated when vulnerabilities are identified or resolved.
  • An SSP is critical for ongoing compliance with regulatory and legal requirements, while a POA&M is a tool to help you meet those requirements by addressing identified vulnerabilities.
  • Ultimately, both an SSP and a POA&M are important components of a successful security program, and organizations should prioritize both to ensure the ongoing protection of their systems.

    ???? Pro Tips:

    1. Definition: You need to know what SSP and POAM stand for and their definitions. SSP is System Security Plan, which is a document that outlines the information system security policies and procedures. POAM is a Plan of Action and Milestones, which is a document that contains the specific tasks that the organization needs to do to reach compliance.

    2. Purpose: You need to understand the purpose of both SSP and POAM. The SSP is a proactive document that helps you establish best practices and security procedures that can prevent security incidents or cyber threats. POAM is a reactive document that establishes specific tasks to address weaknesses and deficiencies identified during the assessment.

    3. Compliance: Both SSP and POAM are essential documents for security compliance. SSP is required by most federal regulations and standards, such as FISMA, HIPAA, and NIST. POAM is a required document if your organization has identified deficiencies or vulnerabilities that require remediation.

    4. Audience: You need to know your audience when it comes to creating these documents. The SSP document is intended for the security team, managers, auditors, and other relevant stakeholders. POAM is primarily used by the IT team, system administrators, and security analysts responsible for implementing security controls and addressing vulnerabilities.

    5. Collaboration: To ensure that both documents are accurate and up to date, there should be a collaborative effort between the security team and IT team. The security team should be involved in the creation of the SSP document, and the IT team should update the POAM based on the security team’s recommendations.

    Understanding the SSP and POAM in Cybersecurity

    In the world of cybersecurity, it is essential to have an understanding of systems security plans (SSP) and plans of action and milestones (POAM). The former is designed to define and document how security measures are implemented and maintained for a given IT system, while the latter is intended to identify, prioritize, and track the successful completion of corrective actions regarding any identified deficiencies or weaknesses within the IT system.

    Defining a Complete SSP and Complete POA&M

    At their core, a complete SSP and a complete POA&M are two different things. An SSP is considered complete if it includes a detailed analysis of how an IT system operates, its architecture, possible vulnerabilities, and the measures in place to avoid and mitigate these risks. Meanwhile, a complete POA&M is an exhaustive list of deficiencies, or vulnerabilities identified within an IT system that require remediation.

    How the SSP is a Living and Working Document

    Unlike the POA&M, the SSP is a living and working document that should be updated continuously. This document provides an overview of the security posture of your IT system. The SSP must be dynamic, continuously updated, and revised as threats progress or vulnerabilities are identified, and new security measures are put in place. If you think of your SSP as a tree, the trunk is the core security policies and practices in place, the branches are the different systems in use, and the leaves would be the specific vulnerabilities that have been discovered and remediated.

    The Importance of adding Information to Your SSP

    A complete SSP includes a vast array of information from a system’s general introduction, categories of data stored or processes that are performed, security risks and vulnerabilities, how risk likelihoods were determined, security countermeasures, and how vulnerability remediation is to be performed. As new vulnerabilities emerge, it is essential to update the SSP to reflect the current security posture of the IT system.

    Benefits of an Empty POA&M

    An empty POA&M does not mean that there are no security risks or vulnerabilities within a given IT system. Instead, it signifies that all identified risks have been effectively mitigated or that no deficiencies have been detected. An empty POA&M suggests that an IT system has been thoroughly assessed, configured sustainably, and may enjoy some of the following benefits:

    • Efficient maintenance of existing security measures: an effort already put in place to avoid and mitigate identified security risks are still active and effective as intended.
    • Mitigated risks: Potential vulnerabilities that are likely to lead to catastrophic outcomes have been identified and mitigated already.
    • No new risks: When auditing your IT system, it is discovered that no new risks have emerged or carryover from existing risks have been remediated.

    Configuration of Office 365 and Other Systems for the POA&M

    When configuring Office 365 and other IT systems, the POA&M should be a primary focus as weaknesses in the system can arise swiftly. Configuration management is the process of tracking all assets and configurations within the IT environment to ensure consistency and best practices. By adopting this configuration management approach, weaknesses that were missed initially may be identified and fixed before causing any damage successfully.

    The Growth of an SSP Over Time

    As time passes, the SSP needs to grow to reflect the current status of the system and evolving risks. Although it may seem like an overwhelming task, it is essential to maintain an informed and timely summary of the security posture of your IT systems. Cybersecurity measures must be proactive rather than reactive, and the SSP should be viewed as an essential tool in achieving this goal. A regularly updated and maintained SSP is the cornerstone of effective cybersecurity.
