What are the best practices of cybersecurity operations? This article will give us an overview. Read this article until the end.
Best Practices of Cybersecurity Operations
Cybersecurity operations are a human-intensive field that requires a high level of organizational maturity, planning, and staffing. The responsibility of cybersecurity operations is to direct the activities necessary to protect an organization from cyber-based threats.
These activities include:
- Identifying current cyber risks to the organization.
- Managing cyber risks through a combination of prevention, detection, and mitigation strategies.
- Identifying new cyber risks as they appear.
- Cybersecurity operations working closely with information security operations and incident response teams to manage detected threats.
- Defining an organization’s security policies and procedures
Cybersecurity Operation Goals
In order to fulfill the mission of cybersecurity operations, organizations must define specific goals or objectives that can be measured against known baselines that reflect acceptable risk levels. For example:
- Minimize the probability of threats occurring (prevention)
- Minimize the effect of threats (detection)
- Lessen the impact of threats (mitigation)
- Minimize the duration that threats affect service (recovery)
- Minimize cost associated with threat response activities (business continuity management)
- Reduce the loss associated with threat response activities (business impact analysis)
- Minimize reputational damage associated with threat response activities (crisis management)
- Minimize adverse impact on external stakeholders (information sharing)
- Maximize compliance with legal and regulatory requirements
- Ensure adherence to corporate policy goals Conduct risk assessments to support key organizational goals
- Conduct vulnerability assessments to inform prevention strategies
- Conduct penetration testing to support risk assessments
- Lead network monitoring for early warning against threats
Define Information Security Policies and Procedures Information
They should define acceptable practices for:
- handling sensitive data
- identify who has access
- define what levels of access are acceptable
- identify what should be monitored
- define information flow restrictions
- know what constitutes unauthorized or inappropriate actions
- define what constitutes legal action
- know how incidents will be handled
- define what should happen if compliance is not met
- establish dispute resolution processes
- establish incident response processes including incident reporting requirements
- know who is responsible for implementing these policies and procedures and who is responsible for monitoring compliance.
Identify Information Assets Information
It includes all hardware and software used by an organization in support of its mission or business functions. This includes everything from laptops used by employees when traveling to servers used by server farms supporting email services to routers supporting large Wide Area Networks.
Identify How Data Flows through Network
The flow of data through networks is controlled by routers that enable communication between computers and network resources such as printers or servers. Data is encrypted as it travels across public networks and is decrypted when it reaches its destination. Data travels through routers, switches, and wireless access points that provide physical connections to the network. The data must be decrypted and re-encrypted as it travels across public and private networks. Mapping data flow through the network will identify the types of encryption required, encryption keys used, and associated encryption algorithms.
Identify Security Controls Security
Identify Security Controls Security controls include security policies and procedures, security technical measures, security management processes, and security personnel. Security policies and procedures define acceptable practices for handling sensitive data. While, security technical measures include firewalls, intrusion detection systems, content filters, antivirus software, encryption software, authentication software, biometrics software, network segmentation to protect key assets from outside attack or damage to key assets from insider threat or accidental damage. Security management processes include incident response planning, incident reporting requirements, dispute resolution processes, risk assessment planning process.
