A network security team can only fight what they can see, an organisation’s network security depends on their ability to rapidly detect and respond to emerging threats across their infrastructure, whether that is Tier 1 Operator, Enterprise or Cloud Provider. However, attack methods and strategies are constantly evolving, making threat detection an always-moving target. A good base to start from is understanding what type of threats may lurking in your network, these threats look very different depending on throughput of network traffic.

A Content Delivery Network or CDN is a system of distributed servers and nodes that delivers web content to a user, based on the geographical location of the user, the origin of the webpage and the content delivery service. The purpose of the CDN is to avoid bottle necks that would occur if every user tried to access content from one central location, the CDN replicates and redirects content so it is available to many users all at once. Ultimately improving user experience across multiple geographical locations (i.e. not just to those users who are physically closest to the server with the original content) and easing pressure on network infrastructure resources.

When protecting carrier scale infrastructure there are a number of good practices and steps to follow to ensure the continued safety and operability of your network. This includes ensuring your cyber security supply chain, which you are reliant on to protect your organisations infrastructure, thoroughly hardens their hardware and software against vulnerabilities.

Cybercriminals are increasingly using application layer Distributed Denial of Service (DDoS) to attack their victims. Unlike a Layer 3-4 DDoS attack that consumes network bandwidth, an application layer or L7 attack can be much smaller in traffic volume and can go unnoticed until too late. This type of attacks effectiveness lies in its ability to mimic genuine HTTP request traffic, usually going unnoticed until it too late. Application layer attacks of this nature are often part of a wider multi-vector DDoS that looks to disrupt different parts of a victim’s infrastructure.

Generally speaking, "East-West" (EW) traffic refers to server to server traffic within a datacentre and "North-South" (NS) to traffic that is routed either to or from anything outside the datacentre.  Depending on the function of a datacentre, EW traffic can be significantly higher than the NS (e.g in a computationally intensive environment), or NS may be the same as or greater than EW (if there are multiple access points) for a data I/O intensive application such as media streaming.

A UDP flood is a type of volume based DDoS (Distributed Denial of Service) attack, where large numbers of UDP (User Datagram Protocol) packets are sent to a target server, limiting its ability to carry out its functions. UDP traffic doesn’t require a three-way handshake to make a connection like TCP (Transmission Control Protocol), it runs with lower overhead and is ideal to carry data that doesn’t need to be checked and rechecked, such as VoIP. This means it is easier for attackers to generate large traffic volumes with tools like Low Orbit Ion Cannon (LOIC) and UDP Unicorn.

…they do not care about vulnerability scores.

The point being that attackers and attacks are constantly changing, often moving at a pace that cyber defenders cannot keep up with, because in order to remain profitable and/or notorious, criminals need to remain one step ahead. Value from illegal online activity can be measured in different ways but almost always it’s about direct financial gain derived from the sale of stolen private data or payments from ransomware.

I attended the Gartner Security and Risk Summit in London last week, where the keynote titled “Scaling Trust and Resilience — Cut the Noise and Enable Action”. The key message was that security professionals are drowning in data, making it difficult to see what is really happening, and to judge “What’s real, what’s important, what’s dangerous”.
