Secure Networking

The network is not only the means for an organisation to communicate with its customers and business partners, and to transfer business critical data to and from applications. It is also the way for malicious users to reach the organisation’s critical assets, to compromise or steal data, or to sabotage performance and resources. Securing the network is critical in order to have a stable and reliable IT environment.

The security technologies range from denial of service protection, through to firewalls and intrusion prevention systems, to secure gateways and decryption analysis tools. However, a stable and reliable network needs more than security products. It also needs clever architecture and design, to meet the rapidly changing business demands, where automation, flexibility and agility are key words.

With next generation we mean that traditional solutions such as network based firewalls have evolved into much more capable solutions.

Increase employee productivity, drive customer revenue and boost business operations. Control and manage your network traffic, ensure peak network performance, always stay on. SecureLink delivers leading, easily scalable network solutions to help meet changing demands.

Denial-of-service attacks threaten to block business critical resources, hindering organisations to serve their customers and do business. To stop these attacks, solutions are required that combine cloud-based mitigation and on-premise protection.

Minimise your attack surface by implementing a segmented network design. Zero trust between segments, secure access, inspection of all traffic and advanced threat protection are some key elements in a modern network firewall design.

The days that traditional perimeter solutions, which typically consisted of a firewall, a forward proxy, a reverse proxy and a mail relay, are over.

It is very difficult to determine today what the actual perimeter is for a company, as we are moving to a more mobile world where everybody needs to have access from everywhere, from every device and where applications are running both on-premise and in the cloud.

According to us we need to distinguish two things, incoming security in order to protect access to resources and outgoing security whereby users and applications are protected from e.g. downloading malware or leaking data.

More and more SSL is used and makes the traditional Security Gateway blind to which data is coming in or going out of your infrastructure. This is something that needs more intention these days.

A next generation security gateway will be a combination of several solutions depending on the actual environment of a customer. What should be taken into consideration is:

  • Protection against zero-day attacks, Advanced Persistent Threats (APT’s) and malware
  • Data Loss Preventions Solutions
  • SSL decryption
  • Next generation hardware: higher throughput
  • Integrated Threat Prevention (IPS, URL, Anti-virus, Anti-malware, Content Scanning)
  • User recognition
  • Signature less detection (behavior and Machine learning based)
  • Virtual form factor to secure a virtualized server environment
  • Reporting and Management
  • Multi-level DDoS protection
  • Application identification
  • Identity and access management for a hybrid application landscape (also see Cloud Security)
  • Separate requirements for outbound and inbound security
  • Integration between different solutions (eg NAC and Security Gateway)
  • Threat Intelligence (threat feeds) for a completely integrated solution

Network boundaries are disappearing, the perimeter no longer provides a zone of trust. Attack surfaces must be met with a segmented network design: zero trust between segments, secure access, inspection of all traffic and advanced threat protection.

Hundreds or thousands of firewall rules and complex infrastructures managed by different teams make network security policy management a challenge. Nevertheless, it is critical for both security and compliance. SecureLink helps automate this, thereby reducing cost and time.

Businesses have traditionally been supported by IT. In today’s world, IT is transformed to actually being the business. With IT as the critical foundation, secure data center networking is a definitive requirement for modern organisations.
