2. Analysis of Internet
Infrastructure Security
2.1 Panel Discussion and Interview Results
On 10 June 2016, as part of the AIS in Gaborone, ISOC and the AUC held a discussion panel on
“Internet Infrastructure Security in Africa”. Interviews were also conducted with selected experts.
The panel discussion and the interviews focused on the following five major topics:
•
What Constitutes Internet Infrastructure and What are Critical Assets
Internet connectivity is identified as the most important function of Internet infrastructure.
The physical assets that make Internet connectivity possible include network devices such
as routers, switches, firewalls, Intrusion Detection Systems, proxy servers, and IXPs. Various
virtual, intangible or abstract components are also needed for the Internet to function, such
as addressing, routing, application protocols and services, security protocols, and the Domain
Name System (DNS).
•
The Security Threat Landscape in Africa
At a fundamental level, the nature of cyber threats in Africa is largely similar to elsewhere
in the world. However, intermittent connectivity is a serious problem, which distinguishes
Africa from much of the rest of the world. Intermittent connectivity is a result of a number
of factors such as insufficient resources in terms of bandwidth, the cost of Internet
connectivity, frequent power outages and blackouts, a lack of effective maintenance and
scheduled patching, a lack of trained workers, natural factors (such as inclement weather),
and human factors (fraud, sabotage, theft, fuel shortage, etc.). Intermittent connectivity limits
the capability of stakeholders to collaborate to prepare for, or to respond to, an attack.

Components of Internet Infrastructure that are Easy Targets of Cyberattacks
Many commercial and industrial systems have embedded software that is out-of-date and/
or unpatched, and are, therefore, especially vulnerable. For example, many financial systems
and public sector networks are dependent on machines running software which is no longer
supported by its developers, and for which security upgrades are no longer available. The
mobile industry also raises similar concerns. In some instances, mobile devices are being sold
with out-of-date or unpatched software. Alongside out-of-date or unsupported software,
an inability or unwillingness to upgrade or patch servers and applications on a regular basis
makes systems vulnerable to attack.
Physical attacks on the infrastructure also pose a threat. The attacks could be intentional
and motivated by financial reasons, political activism, or even terrorism. Physical damage
to infrastructure may also be unintentional, due to factors such as a lack of proper and
regular maintenance on the part of the operators, or negligence due to poor operational and
management practices.
Fiber cuts were cited as an example of physical attacks. It may be difficult to totally avoid this
problem, but solutions to identify and locate cuts would help mitigate the impact. Information
sharing among operators is critical in this regard.
