How secure is your network?
Are your remote workers connecting securely back into the network? Is your traffic encrypted between branch offices and how secure is your connection to the cloud?
Tighter regulation such as The General Data Protection Regulation (GDPR) has increased the burden of responsibility on all companies that process personal data. It requires data controllers and data processors (in effect, IT and network managers) to implement appropriate measures to protect personal data.
Effective security relies on multiple layers of defence at both the edge and core of the network, and along the network path. The challenge is that, as data travels over disparate systems and networks, the network perimeter no longer exists and security measures must adapt.
We’ve mapped out some of the common connections for a modern enterprise, showing why a holistic approach, with security at key vulnerability touchpoints, is an essential part of any IT security strategy.

Physical security is just as important as logical, although it can often be underestimated
Data centre virtualisation has created an environment where it’s now more complicated for data owners to assure themselves of protection - interexchange carriers, multiple cloud hosts, and least-cost-routing algorithms add to the touch points in data transportation where security risks can be higher. Meanwhile the move to edge computing will add more locations where security measures need to be applied.
Along with a secure connection, physical security is just as important as logical although it can often be underestimated. While traffic between Data centres ought to be on a private, dedicated and robust network, it’s also important to consider who can access your data, where it’s stored and its safety in case of emergency.
Data centres secure data in a variety of ways, including multi-factor ID verification, secured racks with supervised access, robust routing and well secured fire suppression systems are all key parts in keeping your data safe.

Maintaining perimeter security has become a major challenge and firewalls can be an unwitting security risk
Connecting to and communicating with customer sites over public internet presents a number of security risks. From Distributed Denial of Service (DDoS) attacks, which have massively increased in size and scale, to data tampering and threat exploitation, deploying a range of security measures is essential to protect both you and your customers.
A firewall is the front line of defense against cyberattacks, yet maintaining perimeter security has become a major challenge and firewalls themselves can become an unwitting security risk if not managed effectively. Enterprises can choose a dedicated firewall, on physical infrastructure, or a virtual one, delivering the benefits of security in a more cost-effective manner. Virtualisation of the firewall enables fast provisioning, unlimited scalability and eliminates your need to maintain a physical network firewall.
Alongside firewalls, Network Traffic Monitoring and profiling systems can help spot malicious traffic early, along with Intrusion Protection Systems (IPS) to keep risks at bay.

IPSec is not designed to support the modern cloud environment, where latency and bandwidth requirements are critical
Sharing data between offices can feel more secure than communicating with the wider world, but there are several security aspects that must be considered, regardless of whether sites are connected via public internet or over a private network.
IPSec has been a legacy method of providing network protection but is not designed to support the modern cloud environment where latency and bandwidth requirements are critical. Therefore, the best practice is encrypt the data-in-motion, not just between offices but also between sites and data centres.

Remote Working »
All VPNs are not the same, which is why it’s important to make sure that your VPN includes end-to-end security
The way we work is changing, and that means people are no longer working the traditional 9-5 and neither are they working from the office. Giving staff the option to work flexibly improves productivity and satisfaction, but can bring security risks unless it’s properly managed. Virtual Private Networks (VPNs) give remote workers access to internal networks and applications, regardless of location.
Remote VPN connectivity can be a point of entry for spyware, hacking, data theft or application abuse, and all VPNs are not the same, which is why it’s important to make sure that your VPN includes end-to-end security.
Intrusion Prevention Systems, firewalls and robust data encryption are just some of the ways to provide security for remote workers. Whether remote workers are connecting to an internal office network, the public cloud or the internet, connectivity should be through a trusted and private network to ensure data integrity and end-to-end security. Furthermore, to ensure security policies are enacted at all times, adequate measures have to be taken at a system and network level.

Identifying malicious traffic is the first step in managing a DDoS attack on your business
With more and more applications hosted on public clouds, your connection needs to be secure and to protect from external threats. DDoS attacks have impacted some of the biggest companies in the world and are increasing in scale and frequency – a report from Neustar found that attacks sized 100Gbps and higher increased by 967% in Q1 2019 compared to Q1 2018. The largest attack measured 587Gbps - more than 70% larger than the biggest attack in the same period in 2018.
Key to effective mitigation is the ability to identify and block attack traffic while allowing non-attack traffic to flow through to its intended destination. Whether it’s a high-volume flood attack designed to exhaust bandwidth capacity or a targeted attack looking to bring down a website, identifying malicious traffic is the first step in managing a DDoS attack on your business.
