The 3 Components of Network Security Policy Management
NSPM is composed of several key elements:
- Policies that outline objectives and restrictions
- Procedures that outline step-by-step actions, standards to establish reasonable configurations and practices
- Other security-enhancing guidelines
These components combine to create a network security policy which is then implemented within the infrastructure to control network traffic. In total, an NSPM creates a framework that ensures consistency of policies and security across the network.
Why is Network Security Policy Management Important?
Here are three reasons why is network security policy management important:
#1: A Comprehensive Approach to Network Security
NSPM provides an effective network security blueprint which plays a critical role in preventing cyberattacks and greatly reduces risk to infrastructure. An organization’s cybersecurity strategy is composed of a variety of security policies, some of which may conflict.
NSPM thus defines a more formal approach to network security management, enabling security administrators to disentangle, coordinate, and standardize policies across organization and infrastructure boundaries.
#2: Enhanced Security and Vulnerability Management
A comprehensive NSPM plan further enhances organizational security by creating a structure to identify vulnerabilities and standardize the implementation of mitigation strategies.
It also supports effective incident response procedures by providing guidelines for handling security incidents – minimizing potential downtime and damage.
#3: Mitigating the Risks of Neglecting NSPM
Organizations that fail to implement NSPM, or who deploy an inadequate NSPM strategy, flirt with severe consequences:
- Financial losses
- Reputational damage
- Legal liabilities
Data breaches may further result in data loss, compromised intellectual property, and regulatory fines.
Creating and Implementing Security Policies
Clear, well-defined policies form the foundation of NSPM. They govern how the organization optimally handle risks and incidents.
- Risk Assessment: Every organization has its own unique threat profile and vulnerabilities. The first step in creating policies is to identify these potential threats, analyze their likelihood and impact, and prioritize areas that need attention.
- Policy Definition: Once the potential risks have been identified, the next step is to develop policies to mitigate them. Acceptable use, data handling and password requirements policies, along with incident response procedures, all require consideration.
- Policy Implementation: Upon defining the requirements of a policy and its scope, the next step is practical application of the policy, which commonly manifests as a rule or command within a network control point such as an individual firewall, virtual security gateway, or intrusion detection system. This makes the policy concrete and begins to shape user behavior and traffic on the network.
- Communication and Training: Security staff and line employees must both understand the policies developed, why they are important, and how to stay in regulatory compliance. Clear communication and training ensures that personnel know what the policies are and how they are enforced.
- Enforcement and Monitoring: Effective policy enforcement requires active monitoring of network usage and behavior, along with regular audits and reviews with stakeholders. These procedures help to identify policy oversights, make updates as needed, and strengthen the entire program.
Security policies must be regularly reviewed and updated to ensure they remain relevant.
Benefits of Network Security Policy Management
Organizations that define clear and coherent policies as part of a healthy NSPM plan benefit from these advantages:
- Enhanced Network Security Posture: NSPM sets forth clear guidelines for establishing network security best practices, reducing vulnerabilities and fortifying the organization against cyberattacks.
- Improved Compliance: The documentation of security controls created as part of NSPM implementation helps organizations better meet regulatory requirements.
- Reduced Risk of Data Breaches: NSPM minimizes the risk of unauthorized access to sensitive data by standardizing on security measures which include strict access controls and network security protocols.
- Streamlined Incident Response: The policies and procedures defined within NSPM support faster, more effective incident response plans, thus minimizing downtime and reducing risk.
- Increased Operational Efficiency: The automation encouraged by NSPM frees up IT resources to pursue other business projects and opportunities.
Examples of Network Security Policies
A variety of standard policies, covering different aspects of network security, are outlined below:
- Acceptable Use Policy (AUP): AUPs define the acceptable use of an organization’s network resources by employees, contractors and guests. It encompasses permissible activities, prohibited behaviors, and consequences for policy violations.
- Password Policy: Define rules for creating secure and complex passwords, including password length and character requirements, expiration intervals, and lockout policies.
- Data Encryption Policy: This policy specifies the encryption requirements for data both in transit and at rest, describing the types of data requiring encryption, the encryption algorithms to use, and key management practices.
- Wireless Network Security Policy: The NSPM should include security measures for wireless network access, covering areas such as access controls, encryption protocols, and SSID broadcasting.
- Remote Access Policy: Remote access of the organization’s network is governed by the NSPM. It covers acceptable remote access procedures, authentication protocols, network device requirements, and security monitoring practices.
These core policies are fundamental to a complete NSPM, and encourage organizations to establish a security-first attitude when building the network environment.
4 Types of Network Security Policy Management Tools
Effective management of network security policies across an organization can be challenging. A variety of tools may be utilized to reduce complexity and streamline adoption of NSPM.
- Security Information and Event Management (SIEM) Systems: SIEMs collect and analyze log data from various sources, parsing them to detect policy violations, misconfigurations, network vulnerabilities, and other risks. They generate alerts on identified problems for rapid remediation.
- Network Access Control (NAC) Solutions: NACs control network access based on device health, user identity, and security compliance. They enforce security configurations, and quarantine or block unauthorized personal devices from connecting to the network.
- Vulnerability Scanners: These tools automatically scan systems and networks for known vulnerabilities. Vulnerability scanners can help ensure weaknesses are quickly detected so that organizations can prioritize remediation of problems in the infrastructure.
- Policy Management Software: These tools provide a centralized location for creation, deployment, enforcement and audits of network security policies. They offer features like automated policy generation, reports, and integration with other security tools.
Leveraging these tools can substantially improve the effectiveness of NSPM.
