Intranet security might not be the most thrilling topic, but it’s crucial in today’s digital landscape. With the average cost of a data breach in the US estimated at $9.48 million, safeguarding sensitive information is paramount.
Contrary to popular belief, internal networks, including intranets, are susceptible to cyber threats. This article explores the latest intranet security best practices, addressing both external and internal threats, and providing tips to develop a comprehensive security policy.
What Is Intranet Security?
Intranet security involves practices and technologies to address security threats and safeguard sensitive data within an organization’s private network.
External Threats to Intranet Security
Even closed, private networks face risks from hackers and malicious software. Firewalls act as a protective barrier between the intranet and the internet, filtering information and providing a crucial first line of defense against network security threats.
- Network Security Threats: Firewalls filter internet traffic based on pre-configured rules, offering protection against various online threats.
- Security Breaches: Effective email filters and security software can block suspicious traffic, preventing security breaches.
- Viruses: Regularly update anti-virus software to protect against evolving virus threats.
Insider Threats to Intranet Security
Internal security challenges often stem from employee errors or negligence, making it essential to address weak passwords, control access, and implement encryption.
- Weak Passwords: Enforce regular password changes and encourage strong, unique passwords to combat vulnerabilities.
- Access Control: Utilize file and page permissions to restrict access based on job roles, teams, or locations.
- Encryption: Employ SSL for encryption, protecting sensitive information from unauthorized access.
- Remote Access: Secure remote access by implementing SSL, VPN, and firewall software, along with additional measures like automatic time-outs.
5 Intranet Security Best Practices in 2023
Navigating the complexities of intranet security requires staying updated on technology, threats, and standards. Here are five best practices to enhance data security in your intranet:
- Develop a Comprehensive Security Policy: Set clear expectations for strong passwords, permissions, and remote work security. Ensure compliance with global standards like SOC2, GDPR, HIPPA, and ISO 27001.
- Secure Log-In Protocols: Implement single sign-on, active directory, or lightweight directory access protocols to strengthen authentication processes.
- Limit Access: Regularly review and update permissions to restrict access based on employees’ current roles.
- Secure Third-Party Software: Ensure API integrations offer secure endpoints to protect against external threats.
- Remote Working: Secure remote employees’ home networks with strong passwords, VPNs, and measures against unauthorized access.
Cloud-Hosted Solutions vs. Onsite Intranets
Modern intranet software is frequently cloud-hosted, providing organizations with a hands-off approach to security responsibilities. Cloud solutions come with secure SSL connections, undergo regular security audits, and leverage the expertise of dedicated providers. Ensuring the security of your intranet is vital for safeguarding sensitive data.
