Networking security


Make your server secure. Find comprehensive information on how to implement and administer different security methods. This information focuses on securing your network connections, transactions, and interactions between other servers and clients.

IBM offers i5/OS cryptography solutions for customers who require a high level of security. A comprehensive cryptography solution is an important part of a successful security strategy. IBM offers a family of cryptographic hardware options for protecting data and for securing transaction processing, as well as a set of cryptographic services APIs that customers can use to customize their programs.

Digital Certificate Manager
Digital Certificate Manager allows you to manage digital certificates for your network and use Secure Sockets Layer (SSL) to enable secure communications for many applications.

Enterprise Identity Mapping
Enterprise Identity Mapping (EIM) for the System i platform is the i5/OS implementation of an IBM infrastructure that allows administrators and application developers to solve the problem of managing multiple user registries across their enterprise.

Intrusion detection
Intrusion detection involves gathering information about unauthorized access attempts and attacks coming in over the TCP/IP network. Security administrators can analyze the audit records that intrusion detection provides to secure the System i network from these types of attacks.

IP filtering and network address translation (NAT) act like a firewall to protect your internal network from intruders.

Network authentication service
Network authentication service allows the System i product and several System i services, such as iSeries eServer Access for Windows, to use a Kerberos ticket as an optional replacement for a user name and password for authentication.

Object signing and signature verification
Find information about i5/OS object signing and signature verification security capabilities that you can use to ensure the integrity of objects. Learn how to use one of several i5/OS methods for creating digital signatures on objects to identify the source of the object and provide a means for detecting changes to the object. Also learn how to enhance system security by verifying digital signatures on objects, including operating system objects, to determine whether there have been changes to the contents of the object since it was signed.

Secure Sockets Layer
This topic describes how to use SSL on your system.

Single sign-on
If you are looking for a way to eliminate the number of passwords that your users must use and that your administrators must manage, then implementing a single sign-on environment may be the answer you need.

System i and Internet Security
Accessing the Internet from your local area network (LAN) requires you to reassess your security requirements.

Virtual Private Networking
A virtual private network (VPN) allows your company to securely extend its private intranet over the existing framework of a public network, such as the Internet. With VPN, your company can control network traffic while providing important security features such as authentication and data privacy.
