Nortel Networks Unified Security
Architecture – ‘Security in our DNA’
Nortel Networks, a global leader in secure data networking, offers proven solutions to satisfy end-to-end
network security requirements. “Security in our DNA” is a key principle of our enterprise strategy –
One Network. A World of choice.
By providing robust network security and working
with alliance partners, our Unified Security
Architecture delivers:
The components businesses need to secure their
information and resources. The help organisations
need to implement a simple single security policy
As more flexible ways of working (telecommuting,
for example) become increasingly widespread,
businesses gain additional entry points and
therefore become more vulnerable to security
breaches. Organisations should not have to
compromise on productivity because of fears over
information security. Unified Security Architecture
allows companies to embrace new ways of working
while retaining the security they need.
Key Components of Security
Nortel Networks has identified 6 components
of security that businesses need to address in
today’s market.
Authentication, intrusion detection and risk
assessment - Integration with third-party systems
provides verification of users and acceptable
utilization.
Protecting confidential data in transit (encryption) -
Virtual private networks and virtual local area
networks protect data through encryption,
tunneling, segmentation, dynamic routing
and more.
Perimeter defence – certified stateful
firewalls protect a network or its nodes against
unauthorised users.
High availability and redundancy of the security
system – Load-balancing, hardware/software
redundancy and failover mechanisms provide
premium uptime and recovery time.
Managing performance demands of security
balancing schemes enable activation of a full
complement of security measures without
performance penalty.
Audit trails – Detailed records of all user and
administrator activity and system events can
identify and deflect potential security issues.
Unified Security Architecture lets organisations
standardise on single platforms for authentication,
encryption, and perimeter defence knowing that
their choice will be supported on the network
infrastructure.
