AS400 iSeries Security – Guaranteeing the Safety of your AS400 Assets

In the looming cyber security landscape, cyber-attacks are likely to cost companies a staggering $10.5 trillion per year, as per McKinsey & Company.

The resources that could be employed to expand business, empower innovation, and build a more promising future for businesses and customers alike will be pivoted toward mitigating cyber threats.

Cyber-attacks are becoming frequent, smart, sophisticated, more expensive, refined, and more threatening to businesses of all sizes and in this evolving era of cybercrime, relying on an age-old security system is like bringing a knife to a gunfight.

The need for robust cyber security measures is more pressing than ever.

So, what about your AS400 iSeries security?

As an IBM i user, do you wonder if you benefit from a special layer of protection that keeps your system safe?

Let’s explore.

How Secure Is AS400? Why It’s a Top Choice for Security, Even Today?

You may start to worry about your IBM iSeries security, which could be a nightmare. But things are not like that.

Just think about the day when you decided to opt for AS400, and you may get to know that your current strategy and procedure already have a solid foundation.

So, the good news is IBM iSeries applications are traditionally secured, making it an excellent platform for protecting business assets.

It has built-in-security components such as two-factor authentication, identity, and access management making it challenging for hackers to attempt an effortless breach.

This established resilient environment makes it a top choice among IT leaders, especially in the 21st century.

If your chosen solution is designed flexibly, you can add modern security features to the current AS400 security software.

AS400 iSeries security is a proven winner and allows a purpose-built application secured in standard web, mobile, and desktop methods. It is the next evolution of the services in such terms.

However, it would be an overstatement to claim that it is inherently secured and doesn’t require any additional security measures to protect it from modern cyber attackers.

As an IBM i user, you might be curious about assessing your system’s resilience against modern cyber-attacks, right?

Let’s understand it in the sense of an example:

AS400/iSeries Security needs users to log in to the application in each session. The security measures start at the time of login and authorization so managing user identity and registration is critical.

IBM security focuses on simplicity while providing specific authorization flows for desktop and mobile apps. Moreover, AS400 iSeries service providers offer out-of-the-box support. You can enable the registration of clients from the management support or even optionally open for public client registration.

From a security standpoint, the advantage is that each request only attracts a small amount of data that the specific microservice needs. So, in the case of any compromise, the petitioner does not get access to the entire system — and gets only the specific data as per the requests.

The record system remains in your IBM i system and becomes the central repository for all your authentication needs. So, the cyber villains would have to cross two levels of authentication.

The proficient AS400 iSeries security service partners offer SSO (Single Sign-On) on the gateway and relay tokens downstream to all other microservices. This is a critical difference from other solutions which allows the authentication to go through clients’ presently used system.

In terms of timing, execution is straightforward, and the service can go out of the box so that you will see minimum downtime to your existing system. In addition to this, there are several benefits that you will see. Such as-

  • Easy token management via client application registration
  • Safe user validation with integrated identity management
  • The ability to allocate access to services
  • Simple user interface

We hope that you have got the answer to your question ‘How secure is AS400?’

As we navigate through the need for robust IBM i security in place, the AS 400 platform, when paired with strategic planning and integration, stands as a reliable defense against cyber villains.

Now, with this example, you have realized the security capabilities of IBM and gained insight into how AS400 iSeries service providers impressively strengthen your iSeries security.

As you now have a deeper understanding of the iSeries security standards, the next important question arises- ”How often should leaders evaluate the security of your AS400 system?”

Let’s unravel.

How Often Should Leaders Audit and Assess their iSeries Security?

Before we dive into the details, let’s enlighten you about the benefits of AS400 Security Software assessment:

The benefits include:

  • Identifying breaches in real-time and in advance
  • Identifying potential vulnerabilities on your IBM i system
  • Check the status of the right controls and remote activity controls
  • Identifying and managing the number of high-level access users on your IBM i
  • Recommend effective solutions to overcome identified security shortcomings

Ironically, many leaders do not take IBM security seriously until they are affected by a significant security incident, highlighting the critical need for a strong security culture.

AS400 iSeries Security evaluation and improvement is usually a reactive process rather than an active one.

Most IBM i users have configured the security of their systems years ago, and now they will change it only if they need a new one or if any security issue arises.

Can you relate?

It’s recommended to perform IBM security audits at least once or twice a year.

You can also get it done on a monthly or quarterly basis. Different AS400 systems have different audit schedules, depending on the nature of the complexity.

For the best answer, consult a trusted AS400/iSeries Security service partner and they can provide tailored recommendations based on your unique system.

As you are well-versed in the significance of security assessment, we have exclusive insights into when decision-makers, like yourself, typically undertake AS400 Security Software assessments.      

When do Technology Leaders Usually Audit and Update their AS400 iSeries Security?

Here is a rough calendar of the times when business leaders using IBM i are most interested and least interested in auditing and updating their IBM AS400 iSeries security.

Let’s look at when the technology leaders like you, are most interested in IBM iSeries security audits and updates:

The security audits occur in the events of –

  • Audit security breaches
  • Major Security breaches
  • Arrival of customer auditors
  • Arrival of regulatory auditors
  • Industry safety rules or regulations affecting security
  • Incorporate last year’s safety points during this year’s audit

The times when leaders are less interested in IBM i / AS400 Security audits and updates:

  • When there is a busy company season
  • When there is summer and winter vacation
  • When there are no immediate safety requirements
  • When there is a problem in engaging with external security consultants
  • When there is a Holiday season such as Thanksgiving or the New Year

In most of these cases, IBM iSeries AS400 security update and evaluation is event-driven rather than active.

It’s ideal to bring in an IBM security consultant to analyse and discover the vulnerabilities that your system may have.

However, there are a few challenges associated with it:

  1. This process can be expensive and IT departments may not always have the right budget for it.
  2. Many security experts hold expertise in Windows server security, network equipment security, and routers. However, very few professionals hold relevant experience in analyzing and updating the intricacies of AS400/iSeries Security.

As a result, it’s relatively easier to find someone to review and evaluate your Windows and network security than to find someone to audit and evaluate your IBM iSeries security.

Now, as you aware of when IT leaders are keen on auditing AS400 iSeries security and when they aren’t, let’s understand how a technology partner can help enhance the security of AS400.
