Security Analytics

Rajat Mohanty the Co-founder, Chairman and Chief Executive Officer for Paladion Networks discusses the importance of Security Analysis

How does the left and right brain theory apply to cyber security monitoring
I frequently get asked by clients whether they should invest in security analytics projects. Over a period of time, I have built up a conceptual framework to put security analytics in the context of overall security operations. Although there are many areas for applying analytics, including risk and compliance or vulnerability management, I will concentrate on threat management where I feel it has maximum applications.

At the broadest level, I try to picture it as a left brain/right brain metaphor. While there may not be strong scientific evidence, the popular notion is that the right brain is involved in identifying patterns, connecting dots and getting the bigger picture while the left half is used for logical, analytical, and deductive thinking. In security parlance, right brain analytics would be used for discovering new things such as abnormal patterns, outlying behaviors, unknown attacks or trying to complete the jigsaw puzzle of an attack campaign when parts of the attacks may be missing from alerts. Meanwhile, left brain analytics would be used to dig deeper once an alert is found to deduce how and when the attack happened, who attacked, and what damage was done.

You can break security analytics in threat management into discovery analytics –right brain and investigative analytics –left brain. These are the fundamental pillars in an active cyber security framework.

When it comes to discovery analytics, there are a plethora of products today which have established the capabilities to detect attacks. Every AV, Firewall, IDS/ IPS, SIEM, and anti-APT have security analytics for this. In addition, there are a variety of threat intelligence products and separate big data analytics, user behavior, and entity behavior analytics. Again, I have tried to create a conceptual framework for this concept.
One can break up the threat into 2 parameters- attack vector and threat actor (attackers) – and plot the four quadrants as known and unknown for actors and vector. Known actors would mean we know something about the attacker, for example, the typical TTPs in a known attack has obvious meaning.

The right half of the graph is all about rules- attacks are known and hence a rule can be created for security devices like IPS, WAF, DLP, SIEM or anti-malware products. Because the attacks are getting more complex and because there are stages to attacks, these rules can be more than just one signature. While purists may not deem such rule writing as analytics, nevertheless, modelling the correct rules is an important part of threat detection. Many of the existing products in this segment are building more and more complex rules when they say security analytics.

The segment quadrant is where the attacks are not known a-priori, but we have some knowledge of the attacker. There is an entire industry that has grown around external threat intelligence. In addition, large enterprises are building up threat intel from their own internal SOC data. Such threat intel can be applied to a variety of data sources including logs, flows, packets, URL access, machine configuration files, etc to generate alerts. Tactical threat intel gets applied directly while strategic threat intel gets modeled into attack trees.

The most classical application of analytics however is in the unknown-unknown quadrant. This is where the statistical and probabilistic models are used for finding outliers, patterns, abnormalities, and attack sequencing. Machine learning is getting widely used for this quadrant and the concept of big data is most relevant here since the underlying data is beyond logs, ingesting a wider variety of machines, networks, packets, and unstructured data.

However, the last quadrant is also the area where you could end up chasing the tools rather than the output. There are so many models, algorithms, and software packages that do machine learning, statistics, and probability calculation that often the discussion is more about the tools and platform capabilities rather than the use cases. Even if you are trying to find unknown-unknowns, it’s still important to pin down the use cases for them.

The Cyber Kill Chain – Determining when rules are needed
That brings us to my third conceptual model – using cyber kill chain to understand why we are building what we are building in security analytics. As the diagram shows, there are some areas of kill chain like exploit and recon and some parts of execute where rules are available in current products. These are represented by red dots. Several other areas like the deliver phase or the install phase are difficult to have rules and hence need analytical models, which are shown as black dots.

These detect waterhole attacks, unknown forms of beaconing, unknown malware installation, lateral spread in networks, data exfiltration without the data being labeled, etc, and are the areas that need analytics as well as rules to solve them. For other places where rules can solve, it is overkill to build analytics. (The red and black dots are only for illustrating the idea and not the exact measurement of what rules are available). So, one way to approach use cases would be to determine what threats you want to detect and whether any rules exist in any of the deployed products before taking up a security analytics project.

I am trying to build a framework regarding left brain analytics, security investigative analytics, what analytics are needed following an alert or incident, or as Gartner says, “hypothesis driven analytics.” I will address this concept in a future post.

With their intuitive operability and superb build quality they are a fantastic set of three.

What’s more, the three lenses are of the same size (68mm diameter x 45mm), have the same filter diameter (49mm) and are almost the same weight (FE 50mm F2.5 G 174g, FE 40mm F2.5 G 173g and FE 24mm F2.8 G 162g) and internal focus so lens interchange is easy – even when using a gimbal. They feature the same stylish exterior design, but focal lengths are clearly marked for quick switches.

The FE 50mm F2.5 G, FE 40mm F2.5 G, and FE 24mm F2.8 G deliver the high image quality of a G Lens, whilst being compact and lightweight. The image quality is achieved by state-of-the-art optics using aspherical elements and ED (Extra-low Dispersion) glass elements, delivering high resolution and suppressing colour fringing. The aspherical elements ensure high-resolution performance in every corner of the image, even from the widest aperture with shallow depth of field. Enjoy shooting in high resolution using a compact design.

The stunning bokeh of the G lens is achieved with the optimisation of a circular aperture and is delivered at the widest point of each lens (FE 50mm F2.5 G F2.5 at 50mm, FE 40mm F2.5 G F2.5 at 40mm, and the FE 24mm F2.8 G F2.8 at 24mm). All three lenses were carefully designed for optimum mobility and are compact and lightweight enough to suit any location. Whether shooting with a full-frame or APS-C body for portraiture, landscape, snapshots or movies with a gimbal and more, the size and weight are balanced perfectly. Experience the benefits of interchanging lenses to suit any scene or subject.

As well as the 50mm angle of view is perfect for portraits and snap shooting stills or movies, the FE 50mm F2.5 G has a minimum focus distance of 0.35m (AF) / 0.31m (MF) and a maximum magnification of 0.18x (AF) / 0.21x (MF), meaning it’s ideal for a variety of scenes and objects. The FE 40mm F2.5 G 40mm angle of view is ideal for snap shooting stills or movies with a minimum focus distance of 0.28m (AF) / 0.25m (MF) and a maximum magnification of 0.20x (AF) / 0.23x (MF). Particularly for movie shooting, 40mm is the preferred angle of view as it corresponds to the natural field of vision and for stills, 40mm allows subjects to stand out against backgrounds.

With a wide 24mm angle of view, the FE 24mm F2.8 G lens is perfect in situations where the background is included, such as gimbal or selfie shooting with a grip attached. And with a minimum focus distance of 0.24m (AF) / 0.18m (MF) and maximum magnification of 0.13x (AF) / 0.19x (MF), you can also shoot close-ups with a blurred background.

Despite their compact size, the lenses feature a focus hold button, focus mode switch, aperture ring, and Aperture click switch for ideal operability. The focus hold button is customisable from the camera menu and can be assigned a function that the user prefers. The aperture ring provides a more intuitive and direct feel, compared to operating the aperture from the camera body when shooting either stills or movies.

The aperture also provides switchable click stops that can be turned off for movie shooting using the aperture click switch. Furthermore, with Linear Response MF, the focus ring responds precisely and linearly when focusing manually so control feels immediate and intuitive, directly reflecting the intent of the photographer and allowing delicate focus adjustments.

The aluminium exterior and engraved Sony logo ensure a premium, sophisticated finish as well as increased strength and durability. Conveniently, the diameter of the filter threads on the hood and the lens barrel are equal (49mm), allowing the same cap and filter to be attached to both the hood and the lens barrel. The lenses are also designed to be dust and moisture resistant to ensure usability in any outdoor environment.

The FE 50mm F2.5 G, FE 40mm F2.5 G, and FE 24mm F2.8 G feature two linear motors to deliver fast, precise autofocus (AF) with excellent tracking performance which is maintained despite instantaneous changes in subject motion – making the lens ideal snapping moving subjects. The AF is also quiet, so works for both still and movie shooting.

The FE 50mm F2.5 G, FE 40mm F2.5 G, and FE 24mm F2.8 G will be available in selected countries in the Asia Pacific from April 2021.
