Taking a holistic view of your security profile is critical to success. Grouping together security best practices and technologies into six primary layers, where each layer overlaps with the others, provides multiple lines of defense. Should one security layer be compromised, there’s a good chance that another layer will thwart a would-be intruder. In part-2 of our 6-part webinar series on the essential layers of IBM i security we discuss intrusion prevention and detection technologies, grouping and protecting related resources within network segments and network traffic encryption.

5. Network Security
The networks to which an IBM i
is connected must be carefully
secured, and if any of these
networks are connected to the
internet, extra vigilance is
required as internet-connected
networks often see thousands
of access attempts each day
by bots, sniffers, and hackers.

8. Inside the Firewall
8
Protect the assets inside your offices and data centers
• Stay up-to-date on security patches
• Segment your network
• Careful use of DMZs
• Even internet network traffic should be encrypted
IBM i Implications:
• Stay current with IBM PTF packages
• Don’t forget insider threats
• Proper IBM i configuration

9. End Point Networks

10. End Point Networks
10
Your corporate network extends across multiple geographies,
all the way into the employee home networks and to the edge
devices
• Protect your critical servers and applications
• Virtual Private Network (VPN) access into your internal networks
• Desktop Virtualization further protects those assets
• Extend monitoring to the employee laptop and mobile devices
• Limit consumer-grade IoT connections
IBM i Implications:
• Consider remote users accessing IBM i resources
• What devices are being used to access IBM i

11. Internet and Cloud

12. IBM i Implications:
• IBM i in the Cloud
• Encrypt sensitive data in motion
• Consider web server and client/server applications
Internet and Cloud
12
Majority of businesses today utilize Cloud-based services and
many leverage the Internet as the corporate backbone
• All traffic over public networks must be encrypted
• Leverage secure web service protocols
• Invest in Virtual Private Clouds to protect your data
• Know your vendors

14. Threat Prevention
14
Secure access to and continuously monitor your network
• Start with strong inventory of all network-connected devices
• Map access management to business need, leverage SSO
• Strong authentication including MFA
• Keep on top of security vulnerabilities with continuous
scanning and patching
• Baseline good network behavior and track anomalies
• Maintain and practice your Incident Response Plan
IBM i Implications:
• IBM i is a high-value target
• Transaction, customer and financial data

15. Top Takeaways
• The corporate network today is global, uses the Internet
as its backbone and includes cloud-based services
• Strong security practices are needed to understand and
provide the appropriate access to end points
• It’s no longer just about the firewall
The Network is the Computer
