How to Manage The Security of Network Services According to ISO 27001 Certification A.13.1.2 ?

ISO 27001 Certification , ISO 27001 Certification


Everyone realizes that information is put away in information systems (workstations, PCs, cell phones, and so forth.), yet to trade the data through a network is necessary.
A large portion of the information systems in this world are associated with a similar primary system – Internet – and, without this system, our general public would look really changed; indeed, the present society as we probably am aware it would not be possible.
Anyway, the Internet isn't the main system applicable for information security. Other, generally utilized systems are, for instance, neighborhood (LAN), portable correspondence systems, Internet of Things (IoT) systems, and so on. They are hosts to numerous administrations that should be secured also.
The A.13.1.2 control of Annex An of ISO 27001 Certification essentially was created for the security of system administrations, and the fundamental standard of this control is to distinguish security components, administration levels, and the board necessities identified with all network services.

Thus, the significant thing here is to deal with the security of the system administrations, including those situations where the administration is re-appropriated.

Security features of network services
All things considered, however what is a system administration? As per ISO/IEC 27002:2013, arrange administrations are fundamentally the arrangement of associations, private system administrations, firewalls, and Intrusion Detection Systems. ISO/IEC 27002:2013 likewise characterizes security highlights of the system administrations, which could be:

·       Network security innovation – This can be actualized through the isolation of systems, for instance arranging VLANs with switches/switches, or additionally if remote access is utilized, secure channels (scrambled) are vital for the entrance, and so on.

·   Configuring of specialized parameters – This can be executed through Virtual Private Networks (VPN), utilizing solid encryption calculations, and setting up a protected system for the confirmation (for instance, with electronic certificates).


·       Mechanisms to confine get to – This can be executed with firewalls, which can channel inner/outer associations, and furthermore can channel access to applications. Interruption Detection Systems can likewise be utilized here, referenced explicitly by the ISO 27002:2013 standard. Fundamentally, Intrusion Detection Systems (IDS) are gadgets that can be founded on equipment or programming, and they continually screen associations with distinguish potential interruptions to the system of the association. They can likewise assist firewalls with accepting or reject associations, contingent upon the characterized standards. Here note that an IDS is a detached framework, since it can just distinguish; in any case, there are likewise Intrusion Prevention Systems, known as IPS, which can avoid interruptions. The IPS are not indicated by the standard, however are valuable and can likewise support firewalls.

So, basically, if you want to manage the security of network services, you can use these types of hardware/software:

·         Routers/switches (for instance, for the execution of VLANs)
·        Firewalls or comparable edge security devices (for instance, for the foundation of VPNs, secure channels, and so on.)
·         IDS/IPS (for interruption recognition/interruption counteractive action)

Network services agreements in ISO 27001 Certification


At this point, we have identified the network services, but if we want to align with ISO 27001 Certification, we need to go one step further. This means that these network services should be included in network services agreements (or SLA, Service Level Agreements), being applicable to internal services provided in-house, and also to services provided from outside, by which I mean those that are outsourced.
So, for the development of a network service agreement, basically you need to consider what network services are established, how they are offered (from inside, or outside, resources, etc.), service levels (24×7, response and treatment of incidents, etc.), and other key components. If the network service is outsourced, it is also important to consider periodic meetings with the external company, and in these meetings it is important to review the SLAs (following the A.15.2 Supplier service delivery management control).

For the security instruments incorporated into the SLA, the determination could be founded on the consequences of the hazard appraisal (fundamentally, for the most astounding dangers, the most grounded security component will be important), utilizing the security controls from Annex An of ISO 27001 Certification), or notwithstanding utilizing the association's contacts with particular vested parties for explicit situations like government, military, and so on., where the execution of explicit guidelines could be required (after the A.6.1.4 Contact with specific vested parties).

Feel secure in your organization’s protection of network services

Keep in mind that all your information is put away in information systems, and they are associated by systems, and the trading of information is conceivable through system administrations (firewalls, IDS, IPS, VPNs, VLANs, and so on.). Thus, on the off chance that you need to have a sense of safety in your association, you should be cautious with the system, controlling the system administrations, distinguishing firewalls, IDS, IPS, VPNs, and so on., and incorporating them in system administrations understandings.
ISO 27001 Certification control A.13.1.2 is a decent asset on the expanding prerequisites for the security of systems. It is case-explicit, and that could be misused to the greatest – which means you can tailor security instruments to your very own prerequisites utilizing the innovation as of now set up. Your association will pick up results; at the same time, considerably more significantly – so will your clients and clients. What's more, they realize how to value having an accomplice in business who considers security to be a profoundly significant point.
