Introduction

This page reports on the Availability and Continuity Plan for the GGUS and it is the result of the risks assessment conducted for this service: a series of risks and treats has been identified and analysed, along with the correspondent countermeasures currently in place. Whenever a countermeasure is not considered satisfactory for either avoiding or reducing the likelihood of the occurrence of a risk, or its impact, it is agreed with the service provider a new treatment for improving the availability and continuity of the service. The process is concluded with an availability and continuity test.

Performances

The performances reports in terms of Availability and Reliability are produced by ARGO on an almost real time basis and they are also collected every 6 months into the Documentation Database (last period July 2017 - December 2017.

In the OLA it was agreed the following performances targets, on a monthly basis:

  • Availability 99%
  • Reliability 99%

Over the past years, the GGUS helpdesk system hadn't particular Av/Co issues highlighted by the performances that need to be further investigated.

Risks assessment and management

For more details, please look at the google spreadsheet. We will report here a summary of the assessment.

Risks analysis

Risk id Risk description Affected components Established measures Risk level Expected duration of downtime / time for recovery Comment
1 Service unavailable / loss of data due to hardware failure Web GUI, Webservices, Databases fail save architecture, virtualisation solution, integration in on call service Medium up to 4 hours (half working day) the measures already in place are considered satisfactory and risk level is acceptable
2 Service unavailable / loss of data due to software failure Web GUI, Webservices, Databases fail save architecture, software in version control, integration in on call service Medium up to 4 hours (half working day) the measures already in place are considered satisfactory and risk level is acceptable
3 service unavailable / loss of data due to human error Web GUI, Webservices, Databases periodical training of on call service staff; system with very restricted access, only accessible by service owner and the team of the on call service Medium up to 4 hours (half working day) the measures already in place are considered satisfactory and risk level is acceptable
4 service unavailable for network failure (Network outage with causes external of the site) Web GUI, Webservices, Databases two independant network provider Low up to 4 hours (half working day) the measures already in place are considered satisfactory and risk level is acceptable
5 Unavailability of key technical and support staff (holidays period, sickness, ...) Web GUI, Webservices, Databases integration in 24/7 on call service Low 1 or more working day the measures already in place are considered satisfactory and risk level is acceptable
6 Major disruption in the data centre. Fire, flood or electric failure for example Web GUI, Webservices, Databases well organized computing center, power supply (USV), fire alarm system, tape backup at different location Medium 1 or more working day the measures already in place are considered satisfactory and risk level is acceptable
7 Major security incident. The system is compromised by external attackers and needs to be reinstalled and restored. Web GUI, Webservices, Databases server configuration according to best practices, most recent patch installation of OS, virus protection, firewall Medium 1 or more working day the measures already in place are considered satisfactory and risk level is acceptable
8 (D)DOS attack. The service is unavailable because of a coordinated DDOS. Web GUI, Webservices, Databases preconnected load balancer, fail to ban, firewall Medium 1 or more working day the measures already in place are considered satisfactory and risk level is acceptable

Outcome

The level of all the identified risks is acceptable and the countermeasures already adopted are considered satisfactory

Availability and Continuity test

The proposed A/C test will focus on a recovery scenario: the service has been disrupted and needs to be reinstalled from scratch. The time spent for restoring the service will be measured, using the last backup of the data stored in it (how much information would be lost?)(risks 1,2, and 6?)(how many other operational tool would be affected?).

Performing this test will be useful to spot any issue in the recovery procedures of the service.
