DNS servers offline is an easy way for attackers
to keep thousands or millions of Internet
subscribers from accessing the Internet. If
attackers incapacitate an ISP’s DNS servers, they
can prevent the ISP’s subscribers from resolving
domain names, visiting websites, sending email
and using other vital Internet services. DNS
attacks have brought down service providers’
DNS services for hours, even days, and in
extreme cases have led to class-action lawsuits
by subscribers.
SSL-induced security blind spots
To prevent the continuous stream of malware
and intrusions in their networks, enterprises need
to inspect incoming and outgoing traffic for
threats. Unfortunately, attackers are increasingly
turning to encryption to evade detection. With
more and more applications supporting SSL – in
fact, over 40% of applications can use SSL or
change ports– SSL encryption represents not
just a chink in enterprises’ proverbial armour,
but an enormous crater that malicious actors
can exploit. While many firewalls, intrusion
prevention and threat prevention products can
decrypt SSL traffic, they can’t keep pace with
growing SSL encryption demands.
Brute force and weak authentication
Applications often use authentication to verify
the identity of users. With authentication,
application owners can restrict access to
authorised users and they can customise
content based on user identity. Unfortunately,
many application owners only enforce singlefactor, password-based authentication. With
weak single-factor authentication, application
owners are exposed to a host of threats, from
simple password guessing and stolen credentials
to highly automated brute force attacks from
password cracking tools.

International Data Corporation (IDC) has completed an indepth market sizing of the EMEA Big Data infrastructure market
focusing on servers, storage, and cloud resources used for Big
Data–related activities. These include value creation from
merging different data sources, various analytics, log files, and
metadata that help identify patterns and generate predictions.
IDC forecasts that Big Data–related server shipments will
increase from 6% of all servers shipped in EMEA in 2015 to
16% by 2019, and server values from $1 billion in 2015 to
$2.7 billion by 2019.
Big Data storage capacity share of new shipments is expected to
reach 20 exabytes by 2019, with a value of $2.7 billion.
According to our market sizing, 134,000 server units were shipped
for Big Data purposes in 2015, and 764 petabytes of storage
capacity deployed, with the majority being external storage.
While most current Big Data projects are starting off in
companies’ own data centres, analytics workloads are
increasingly being moved to the public cloud while sensitive
data needs to remain on-premises in many cases for
compliance reasons.
IDC expects the public cloud infrastructure share of Big Data
workloads to increase from 13% of server shipments in 2015
to 34% by 2019, and new storage capacity deployed on public
cloud infrastructure to increase from 25% of Big Data workloads
in 2015 to 55% by 2019. Most customers are expected to
deploy some form of hybrid solution.
