A cybersecurity framework is a group of documents that outline guidelines, security-related standards, and best practices to help organizations manage and protect their assets from cybersecurity threats. The goal of any InfoSec framework is to identify and remediate vulnerabilities to prepare your organization and minimize the potential risk of vulnerabilities.
example Cybersecurity framework include NIST Cybersecurity Framework, the ISO 27001 framework, the Cybersecurity Maturity Model (CMMC) developed by the US Department of Defense (DoD), and the Payment Card Industry Data Security Standard (PCI DSS). Legit Security has brought together many of these frameworks. best practice This dramatically reduces software supply chain risk.
Analysis of the Five Elements of the NIST Framework
The NIST Cybersecurity Framework (NIST CSF) is a set of guidelines developed by relevant stakeholders to improve cybersecurity risk management for critical infrastructure, protecting increasingly connected and complex systems. , endangers the security, economy and public safety of the United States. NIST’s core competencies align with his five NIST functions: identification, protection, detection, response, and recovery. These five security functions are becoming increasingly important for organizations in every sector and community. Dig deeper into each to identify the most important aspects of protecting your organization.
First feature of NIST CSF, Identifying assets that are critical to your organization and understanding their risks (aka NIST Asset Management)The main activities that take place during this phase are:
- Identify physical and software assets within the organization to establish the foundation of an asset management programwhich allows organizations to contextualize which assets are relevant Continue Elements of the IT security framework.
- business identification environment, organization supports, When how Its products are relevant to the standards required for: organization takes Department of of supply chain of Securing Deadly business assets.
- Identify the cybersecurity policy established within the organization to define the organizational governance program and whether it corresponds to the organizational governance program Legal and regulatory requirements for cybersecurity.
- as the foundation of the organization Risk donkeysMento, identification assets Vulnerability When threats to internal and external organizational resources; Includes establishing risk tolerance For defined threat models.
- Supply chain identification Risk management strategy, Includes priorities, constraints, risk tolerances and assumptions used to support risk decisions related to management supply chain risk.
The second function of the NIST CSF is to protect an organization’s critical assets from cybersecurity threats. This includes implementing safeguards such as security controls and protocols to protect critical services and prevent unauthorized access to sensitive information. As a continuation of NIST asset management, the key activities that should be performed during this phase are:
- setting protate Identity management and access Hacontrol As a basis for minimizing the exposure of confidential information within the organization. this is, Limit and contain the impact of cybersecurity incidents.
- Awareness and training program Empower staff within your organization in the meantime emphasize Difference from privilege non-privileged user.
- Confidentiality protectionInformation integrity, availability by establishing data security protection matching of the organization risk strategy, potentially derived from NIST impact level.
- under implementation Information protection process Procedures for maintaining information systems and asset protection.
A third feature of the NIST CSF is detection A cybersecurity incident that occurred. This includes implementing monitoring and detection systems that alert organizations to potential threats and enable them to respond quickly. The processes in place during this phase help determine the extent of proactive threat detection within your organization. The key processes that should be performed during this phase are:
- Creation procedures Me andinformationS.ec framework as foundation that Anomalies and Events Reliably was detected and that Organization understands the potential blast radius of each event.
- Validate the effectiveness of existing safeguards and implement new safeguards Features that help you monitor cybersecurity events To secure the organization is Protect, detect and respond in a timely manner.
- current rating process Ensure that the discovery process is maintained continuously Provide your organization with alerts and visibility when unusual events occur.
The fourth feature of the NIST CyberSecurity Framework is respond In the event of a cybersecurity incident. This includes having well-defined incident response and escalation plans to enable the organization to effectively respond to and recover from incidents. It also enables organizations to remediate quickly and effectively in the event of an attack, minimizing potential damage. It’s the third layer in the protection-detection-response triad and the motto that most, if not all, InfoSec frameworks require organizations to adhere to. Activities ideally performed at this stage include:
- guarantee it Be ready to execute a response planning process during and after an incident Mitigate and Investigate Possibilities incident damage Caused.
- m’s protocol isAnagof Communication with all stakeholders during and after the event in a suitable location, including Law Enforcement and External Stakeholders, if relevant.
- Formulation of analysis plans to be carried out to do so Verification of effective response Support recovery activities including forensic analysis and determination of incident impact.
The fifth and final function of the NIST CSF is focused on identifying activities that help restore resilience and recover from cybersecurity incidents. This includes implementing measures to restore normal operations and mitigate the impact of the incident on the organization. The efforts an organization makes to its recovery components have a direct impact on its ability to contain the impact of a cybersecurity incident and minimize potential damage. This capability, in addition to the Protect, Detect, and Respond triad, is one of NIST’s most important core competencies because it determines the scale of damage that a potential cybersecurity incident can inflict on an organization. The main activities that should be performed during this phase are:
- Guaranteee The recovery planning process implemented Have system restore procedures in place; Mitigate the consequences of cybersecurity incidents.
- Continuously learning and improving recovery strategies based on industry standards, Other cybersecurity incidents and ongoing review of current strategy.
- Planning for coordinating internal and external communications during and after recovery from a cyberattacksecurity incident.
Why the NIST Framework Matters
of initial Purpose of the NIST CSF It was to help protect America’s critical infrastructure. but we can see this more clearly framework is relevant for everyone Organizations that need to ensure security their operation Various cybercriminal environments.In the past, security is traditionally considered end of software development Lifecycle (SDLC).TToday’s increasingly hostile cybersecurity environments together jobsS‘ increased reliance on Digital service request that organization Also put extreme caution upon Security of the entire development environment before production and SDLC By adhering to IT security frameworks such as the NIST CSF. Like above-mentioned, P.corrupt, D.detect and When R.Supported operating models Pillars of this framework. it should It is the motto of an organization that wishes to protect itself From cyber security threats, Create a cybersecurity plan.
Adopt a NIST approach to keep your software supply chain secure
The InfoSec framework’s role is to help organizations protect their environments by providing a set of guidelines and safeguards for organizations to follow. NIST’s five functions—Protect, Identify, Detect, Respond, and Recover—are similar to other leading security frameworks, but are critical to helping minimize the impact of cybersecurity incidents on organizations of all sizes. contains many steps. In addition to these guidelines, Legit Security: 10 steps set This helps protect the software supply chain, an increasingly important component in securing an organization’s overall digital business model.
