The security issues that cause the most trouble are often ordinary things left unmanaged: an old account, a missed patch, an overprivileged administrator, a weak backup process or a cloud setting nobody has reviewed in years. Good cybersecurity is the discipline of finding and fixing those gaps before they become an incident.
Cybersecurity is no longer a separate IT project. It is part of day-to-day business risk management.
Huff Data Systems helps businesses strengthen cybersecurity across endpoints, networks, Microsoft 365, identities, cloud services, backups and business processes.
What Business Cybersecurity Should Accomplish
A cybersecurity program should reduce the likelihood of an incident, improve the ability to detect suspicious activity and give the organization a workable plan for responding and recovering.
No security provider can guarantee that a business will never experience a cyberattack. Effective cybersecurity is based on layers of controls that reduce risk and limit the impact of an incident.
Core Cybersecurity Areas
A business cybersecurity program commonly includes:
- Asset inventory
- Software inventory
- Secure configurations
- Vulnerability and patch management
- Endpoint protection
- Managed detection and response
- Identity and access controls
- Multi-factor authentication
- Email security
- Network security
- DNS and web security
- Backup and recovery
- Security logging
- User awareness
- Incident response planning
- Vendor and third-party risk management
- Cybersecurity policies
- Compliance documentation
Identity Security
Attackers increasingly target user accounts because a valid account can provide access without exploiting a traditional software vulnerability.
Organizations should protect identities with strong authentication, multi-factor authentication, appropriate administrator separation, lifecycle management for users, conditional access where appropriate and monitoring for suspicious sign-ins.
Former employees and abandoned accounts should be disabled promptly.
Microsoft 365 Security
Microsoft 365 can contain email, files, Teams data, identities and business records.
Important security considerations include:
- Multi-factor authentication
- Administrative role management
- Conditional access where licensing and requirements support it
- Email authentication
- Anti-phishing protections
- External sharing controls
- Audit and security logging
- Device access
- Backup and retention requirements
- Application and OAuth permissions
- Security alert review
Endpoint Security
Business endpoints should be centrally managed and protected.
A mature endpoint strategy can include patch management, secure configuration, endpoint detection and response, disk encryption, application controls, local administrator restrictions and inventory management.
Network Security
Network security can include properly configured firewalls, segmentation, secure remote access, wireless security, DNS protection, intrusion prevention and controlled administrative access.
Organizations with operational technology, industrial systems or specialized devices may require additional segmentation and risk assessment.
Managed Detection and Response
Preventive controls are important, but organizations also need the ability to detect activity that bypasses prevention.
Managed detection and response combines security telemetry with investigation and response processes. The objective is to identify meaningful suspicious behavior and respond before an attacker can cause greater damage.
Backup and Ransomware Recovery
CISA recommends organizations maintain backups and take steps that reduce the impact and likelihood of ransomware.
A business should not assume that a successful backup job automatically equals recoverability. Recovery procedures should be documented and tested.
Important considerations include backup isolation, retention, administrative access, recovery priorities and restoration testing.
Cybersecurity Frameworks
The CIS Critical Security Controls are a prioritized set of safeguards organizations can use to build and improve a cybersecurity program.
CIS divides implementation into three Implementation Groups:
- IG1: foundational cyber hygiene
- IG2: additional safeguards for organizations with greater operational complexity and risk
- IG3: additional safeguards for organizations facing higher risk or sophisticated threats
The correct target depends on an organization's size, technology, data, threat profile, regulatory requirements and business risk.
Cybersecurity and Compliance
Compliance does not automatically mean an organization is secure, and cybersecurity does not automatically prove compliance.
However, a structured cybersecurity program can provide the technical and administrative foundation required by many regulations, contracts and insurance requirements.
Huff Data Systems can assist organizations with technical controls, documentation and cybersecurity planning. Legal interpretation should be performed by qualified legal counsel when required.
Incident Readiness
Before an incident occurs, businesses should identify:
- Who has authority to declare an incident
- Who contacts cyber insurance
- Who contacts legal counsel
- Who communicates with customers
- Which systems are most critical
- How compromised accounts are disabled
- How evidence will be preserved
- How systems will be restored
- Which vendors must be contacted
- How decisions will be documented
Common questions
Is antivirus enough?
No single security product is enough to protect a modern business. Effective cybersecurity requires multiple layers covering identities, endpoints, networks, email, cloud services, data, backups and people.
Does MFA stop all account attacks?
No. Multi-factor authentication is an important control, but organizations must also manage phishing, session theft, malicious applications, compromised devices, account recovery and administrative access.
What is a cybersecurity assessment?
A cybersecurity assessment reviews the current environment, identifies weaknesses and compares controls against a defined standard, risk model or organizational requirement.
How often should cybersecurity be reviewed?
Cybersecurity should be managed continuously. Formal risk assessments and program reviews should also be repeated periodically and when significant changes occur.
