• Guru: Serve Web Pages Safely Using A Reverse Proxy

  July 23, 2018 Alan Seiden

  If you are hosting a website or API from your IBM i server, but wish to reduce your worry about allowing access from the Internet, we often recommend a reverse proxy (or “gateway”) server. An industry-standard solution, a reverse proxy server acts as a layer of safety between your production server and your firewall. On IBM i, the IBM HTTP Server (powered by Apache) for i can act as a reverse proxy server, so there’s nothing additional to install.

  While there are several ways to set it up, one approach is to put the reverse proxy or gateway in a …

  IBM has issued patches to fix a serious security problem in the IBM Global Security Kit, or GSKit, a relatively obscure crypto package that implements SSL/TLS encryption algorithms across a variety of IBM products, including IBM i. An old flaw in the underlying RSA crypto algorithm that could let hackers decrypt data in a “side channel” attack has resurfaced under a new moniker: “ROBOT.”

  GSKit is an IBM toolkit that implements various encryption-related functions, including symmetric and asymmetric ciphers, random number generation, hashing algorithms, and encryption key management capabilities, for products that need over-the-wire encryption, including IBM i, Linux, and …

  Last month’s Technology Refreshes for IBM i 7.2 and 7.3 brought a number of enhancements to the operating system and the database. But one should not overlook the new stuff coming to IBM i Access Client Solutions (ACS), including changes to the 5250 emulator, extensions for database access, and security enhancements.

  ACS, in case you forgot, is the new go-to client interface that administrators, developers, engineers, and power users alike can use for handling a range of IBM i tasks. The Java-based product, which IBM unveiled back in August 2012, bundles a bunch of useful goodies into a single product, …

• Top Ten New IBM i RFEs

  May 22, 2017 Alex Woodie

  Should IBM open source its database drivers, or add support for .NET? Should it add the latest SSL ciphers to IBM i 7.1? These are some of the changes that it has received through its new Web-based requests for enhancement (RFE) program on its developerWorks site.

  The new RFE functionality is only a few months old, but it’s already attracting the attention of IBM i professionals who want IBM to change things about the stack. It’s also getting attention from other IBM i pros who get to vote on them.

  Here are the top ten RFEs so far, ranked by …
