Ensuring security in your IT transformation

James Wong, Managing Director, South Asia, A10 Networks | Jan. 30, 2015
With social networking, mobile devices and cloud computing solutions being used more pervasively, we will see a transformational change in how service providers and large organizations deploy and enable security in their revenue generating network infrastructure.

In addition, a robust security solution that can readily integrate with their existing IT infrastructure is required to protect against DDoS attacks. This can include a feature set for traffic management to ensure high availability and selective delivery of subscriber services. Together, these physical and virtual systems must be able to ensure that network operators can also expand their network capacity, mitigate threats, and exert greater content control.

Scaling security devices and encrypted communications is a critical requirement as the network grows in complexity and size. Service providers can build robust layer 7 safeguards by leveraging products that offer agile defense mechanisms against more subtle attacks such as Slowloris and Tor's Hammer to protect against seemingly legitimate traffic streams exploiting application vulnerabilities.

As more new devices are added to the network, they need to be integrated into the operator's security system to meet policy and compliance requirements. TechTarget reports that new appliances today are capable of performing policy-based networking actions in hardware such as the ability to implement security functions — like traffic management or cloud security policies - to protect the performance and availably of applications and ensure large customer-facing networks are free from disruption. ADCs and CGNS, for example, sit at the critical ingress to most networks and is a natural place to locate advanced security capabilities so threats can be stopped or mitigated before they can enter the network.

Other measures that enterprises and network operators can take to strengthen their network defense include adopting multiple complementary approaches to security enforcement at various points in the network, therefore removing single points of security failure; incorporating people and processes in network security planning; employing security policies, security awareness training and policy enforcement; and maintaining the integrity of the network, servers and clients by ensuring the operating system of every network device is protected against attack by disabling unused services.

As enterprise and service provider networks evolve, ensuring security will become a compulsory IT requirement - and not a 'nice-to-have'. Security breaches span access, infrastructure and applications across every industry. They can happen on both fixed and mobile networks and destroy your physical, intellectual and financial capital. Any downtime resulting from breaches on the network can have a devastating impact on your customer's experience, your brand reputation, and ultimately your revenue and sustainability of your business.
