1 Compliance 101: Basics for Security Professionals In today s regulatory environment, businesses can be subject to a number of industry standards and regulations, many of which include substantial penalties for non-compliance. These mandates affect corporate functions far beyond just Compliance, however IT Security in particular. Security professionals whether they re new to their role or have been around since VirusScan was the cutting-edge tool should have a basic understanding of how compliance impacts the organization, including the stakeholders, the standards and regulations to which the business is held, and what needs to be done to ensure continued compliance. Compliance is not voluntary and non-compliance can result in a mandatory business disruption or even stoppage until a compliant state is reestablished. Therefore, it behooves Security pros to understand their role, as well as other implications of compliance, and this eguide aims to help get them started. eguide Compliance 101: Basics for Security Professionals 1

2 Why Be Concerned About Compliance Compliance with industry standards and regulations has wide-reaching impacts, for both internal and external stakeholders. Organizations dedicate human and financial resources toward compliance for a number of reasons: to avoid liability at the Board and C-level to preserve their corporate reputation to keep their bottom line safe and shareholders happy to avoid the cost of compensating customers when sensitive data is stolen to avoid litigation costs; and to avoid the additional costs associated with increased scrutiny from regulators The consequences of not meeting compliance in the presence of a compromise or a compelling event can have a considerable negative impact on any business, so it s imperative to understand the causes of non-compliance along with the impacts associated with increased liability. eguide Compliance 101: Basics for Security Professionals 2

3 Compliance Questions to Consider Here are just a few of the questions to consider to help familiarize yourself with the compliance function. It s certainly not an exhaustive list but these items will help you start to understand the scope and impact of compliance on your organization. Is your organization held to any compliance regulations or standards? (The answer is almost certainly yes. ) Some examples include: Sarbanes-Oxley FISMA How does your organization validate and measure its compliance posture and risk to that posture? How does your organization control in-scope assets and collect compliance information? Does your organization use a third-party assessment entity? Who is that entity, and what do they provide to help meet compliance? eguide Compliance 101: Basics for Security Professionals 3

4 The Compliance Players Nearly every internal stakeholder in the organization is attached in some way to the corporate policy. The following list covers the primary players responsible for creating the core policies that establish the organization s compliance posture. Establishes the tone for risk appetite and risk management and consider risk and security strategy. Establishes the operational strategy for security and risk management in the organization. Sets strategic and tactical roles and responsibilities. Often responsible for approving or denying select IT policy and security budgets and spend. Develops the security policy, and conducts the risk assessments that base the process for vulnerability management, incident management, security awareness and training and Compliance management. Responsible and accountable to deliver the executive policy to the employees. Must ensure and prove compliance with IT policy. eguide Compliance 101: Basics for Security Professionals 4

5 The Convergence of Security and Compliance While it may not always be apparent, Security and Compliance are counterparts on a path to a shared goal: managing the organization s risk. In this regulatory world, virtually every organization is subject to industry standards and/or regulations, and compliance is becoming one of the greatest challenges faced by IT organizations. Now that observing regulatory compliance audit policies is becoming a requisite for every organization, IT spending, priorities, and policies must be put in place across organizational teams to address the challenge. On top of that operations and security teams have a long list of priorities and pressures to deal with. These days, sensitive enterprise data is always at risk of being compromised; therefore, it has also become a mandate to secure that information by establishing security processes that address the current threat. With these constraints and what seem to be conflicting priorities, it s no wonder that the convergence of security policies and compliance controls has not been seamless. There is hope, however, so let s dig in to explore why Security and Compliance are really counterparts on a shared path to the same business goal. eguide Compliance 101: Basics for Security Professionals 5

6 Regulations with a Big Bite Organizations need to ensure compliance with all standards and regulations applicable to their industry, keeping in mind that some mandates (e.g. Sarbanes-Oxley) are horizontal in nature. We re highlighting the following five standards and regulations because they have a big bite when it comes enforcement, penalties and remediation. They are also commonly associated with media headlines and the news is typically not good for any organization called out in such reports.

12 The Fundamentals of Compliance Controls IT security and compliance professionals must ensure continuous compliance with industry standards and regulations, or face undesirable consequences such as fines and brand damage. A compliant state is built on 5 fundamental core controls, which are common across all major regulations and standards. 1. Identify, classify & scope critical business processes 2. Monitor and prevent change 3. Measure, identify and analyze risk 4. Detect and prevent malware 5. Actively enforce policy We ll explore each of these at a high level on the following pages, including a comparison of traditional methods vs. a positive security approach. eguide Compliance 101: Basics for Security Professionals 12

13 IDENTIFY, CLASSIFY & SCOPE CRITICAL BUSINESS PROCESSES A foundational security control associated with nearly every standard and regulation speaks to inventorying/ identifying/classifying (or insert other applicable verb here) critical data. However it s labeled, this essential control requires the organization to pinpoint where the critical data resides so it can be safeguarded, with auditable proof. Traditional Approach Positive Security Approach Manual process of identifying and classifying files Cumbersome and static, relies on scan-based technologies Real-time sensor provides visibility into what s running at any point in time Continuous monitoring and recording of all endpoint activity, providing details about processes, including where/how they originated and if they created child processes eguide Compliance 101: Basics for Security Professionals 13

14 MONITOR AND PREVENT CHANGE The next common control covers file integrity and is typically called File Integrity Monitoring or FIM. This essentially requires organizations to ensure that unauthorized changes to critical files, such as operating system and core application files, do not occur. Such a change or attempted change is an indicator of compromise and, therefore, must be taken seriously. Traditional Approach Positive Security Approach Identify and analyze all changes after they ve occurred, potentially resulting in significant administrative burden No easy way to filter authorized changes vs. unauthorized changes, producing a lot of noise for the security team Introduce control (i.e. File Integrity Control), using policy to prevent unauthorized changes from occurring and eliminating the need to do post-event analysis Filter out all irrelevant changes and focus only on changes that are important to security and compliance eguide Compliance 101: Basics for Security Professionals 14

15 MEASURE, IDENTIFY AND ANALYZE RISK Most standards and regulations require organizations to identify and analyze the compliance risk caused by the introduction of vulnerabilities into the enterprise. This helps organizations understand the impact that these vulnerabilities have on their compliance posture. Traditional Approach Reactive, manual vulnerability classification & remediation, subject to human error Relies on sources such as news groups and other occasionally-updated feeds Positive Security Approach Proactive, automated vulnerability and threat identification based on real-time intelligence Dynamic updating, using cloud-delivered threat and reputation intelligence from dozens of sources Desktops & Laptops Windows & Macs Virtual/Physical Servers Fixed-Function Real-time Updates No Scanning! No Polling! Console { Real-time and Recorded Data Big Data Analytics Open APIs Threat Indicators Visibility: Instant Intelligence All File Modifications All Registry Modifications Copy of Every Executed Binary Threat Intelligence Reputation Attack Classification Detection: Identify Threats All File Executions All Network Connections All Cross-Process Events Cloud-delivered Advanced Threat Indicators (signature-less) Cloud-delivered Attack Attribution Cloud-delivered Reputation eguide Compliance 101: Basics for Security Professionals 15

16 DETECT AND PREVENT MALWARE Compliance standards and regulations call for the detection and prevention of malware, as the introduction of such files can clearly lead to security and compliance concerns. Regardless of the compliance standard, this requirement is almost universally written identifying anti-virus technologies as the means to ensure compliance. Traditional Approach Positive Security Approach Based on negative, blacklisting type approach Essentially impossible to keep up with the list of known bad file hashes, which changes by the minute Scanning requires heavy use of processing resources Blocks any untrusted processes from executing Does not require updating and maintaining a list of known bad hashes Lightweight sensor uses minimal processing power and does not require constant scanning or frequent endpoint updates eguide Compliance 101: Basics for Security Professionals 16

17 ACTIVELY ENFORCE POLICY A final common control aims to ensure that the security and compliance policies are pushed out to the entire organization and that each of the stakeholders understands his/her roles and responsibilities under that policy. Traditional Approach Positive Security Approach No audit trail of policy acceptance and testing Often ad-hoc, with no method to enforce compliance Results in increased compliance costs if third party organization is hired Full audit trail of policy awareness Policies are pushed out automatically, with auditable evidence of consumption Can be managed in-house, minimizing compliance costs eguide Compliance 101: Basics for Security Professionals 17
